<div>==Tutorial Per Instal·lar Riot==<br />
===Linux Mint===<br />
<br />
Primer he de saber quina versió de Linux Mint estic fent servir.<br />
Per aconseguir-ho cerco a Menú/Preferències/Informació del sistema<br />
<br />
En el meu cas és: Linux Mint 18.2<br />
<br />
Després vaig a veure en quina versió d'Ubuntu està basada. Ho puc veure a:<br />
<br />
https://en.wikipedia.org/wiki/Linux_Mint_version_history<br />
<br />
En el meu cas la versió 18.2, és la que du de nom en codi "Sonya" i està basada en ubuntu 16.04 de nom en codi "Xenial Xerus".<br />
<br />
Ara ja puc seguir el tutorial web:<br />
<br />
https://linuxconfig.org/install-riot-matrix-chat-client-on-debian-and-ubuntu<br />
<br />
Al fitxer /etc/apt/sources.list amb permisos de superusuari escric la següent linea:<br />
<br />
deb https://riot.im/packages/debian xenial main<br />
<br />
(ull: escric xenial perquè la meva distribució està basada en xenial, canvia xenial per la teva que has cercat com explica més amunt)<br />
<br />
<br />
Tot seguit em descarrego la clau GPG per a fer servir el repositori amb:<br />
<br />
$ wget https://riot.im/packages/keys/riot.asc<br />
<br />
I la instal·lo amb:<br />
<br />
$ sudo apt-key add riot.asc<br />
<br />
<br />
Ja està tot llest perr a la instal·lació:<br />
<br />
$ sudo apt update<br />
<br />
$ sudo apt install riot-web<br />
<br />
<br />
Si tot ha anat bé trobarem la icona de riot al menu/internet/ cliquem dues vegades i ja està, ens apareix la pàgina inicial de riot.<br />
<br />
===Debian===<br />
<br />
Primer m'assabento de quina versió de debian tinc instal·lada. Ho puc mirar al fitxer /etc/apt/sources.list amb l'ordre:<br />
<br />
$ cat /etc/apt/sources.list<br />
<br />
<br />
En el meu cas és Jessie.<br />
<br />
<br />
Modifico el fitxer /etc/apt/sources.list afegint la linea:<br />
<br />
deb https://riot.im/packages/debian jessie main<br />
<br />
<br />
Tot seguit em descarrego la clau GPG per a fer servir el repositori amb:<br />
<br />
$ wget https://riot.im/packages/keys/riot.asc<br />
<br />
<br />
I la instal·lo amb:<br />
<br />
$ sudo apt-key add riot.asc<br />
<br />
<br />
Ja està tot llest perr a la instal·lació:<br />
<br />
$ sudo apt update<br />
<br />
$ sudo apt install riot-web<br />
<br />
<br />
Si tot ha anat bé trobarem la icona de riot al menu/internet/ cliquem dues vegades i ja està, ens apareix la pàgina inicial de riot.<br />
<br />
===Ubuntu===<br />
<br />
El procés d'instal·lació és el mateix que al Linux Mint si bé és més fàcil mirar la distribució que tenim, només hem de mirar-ho al fitxer /etc/apt/sources.list<br />
<br />
I tot seguit l'editem com s'explica al tutorial per a Linux MInt.<br />
<br />
La resta de passes han de ser les mateixes.<br />
<br />
===Android===<br />
Ens podem descarregar l'app "riot" des del repositori F-Droid.<br />
<br />
Si no tenim el repositori instal·lat ens el podem instal·lar obrint la pàgina web de l'F-Droid:<br />
<br />
https://f-droid.org/<br />
<br />
i clicant allà on diu "DOWNLOAD" des d'un navegador del nostre smartphone Android.<br />
<br />
Una vegada ens hem instal·lat F-Droid. Actualitzem el repositori i cerquem i instal·lem riot seguint les instruccions de l'aplicació.<br />
<br />
==Registrar-se a Riot==<br />
<br />
Una volta hem arrencar l'aplicació a la part superior esquerra ens apareixen la opció registrar-se, cliquem i s'ens obre una finestra que ens demana mail, telefon, pais del telefon, nom d'usuari i contrasenya. Sembla que només el nom d'usuari i la contrasenya és obligat. Tanmateix si li poses el mail i el telefon els teus amics et podran trobar per ells i també pel teu nom d'usuari.<br />
<br />
Jo li he posat el nom la contrasenya i el mail, quan he clicat a registrar m'ha enviat un mail en el qual he de clicar en l'enllaç que em diu i ja estic registrat.<br />
<br />
<br />
==Accedir a la sala de Calafou==<br />
<br />
Has rebre un mail d'algú que ja hi sigui aconvidant-te.<br />
Quan rebis el mail trobaràs un enllaç per activar el grup. Clica'l. Se t'obrirà al navegador la interfície de riot, logueget a la interficie i llavors torna a clicar l'enllaç del mail. Et demanarà si vols activar el grup cliques que si i ja el tens. Marque'l com a preferit i ja està a disfrutar.<br />
<br />
==Crear una nova sala==<br />
<br />
Les noves sales es creen a partir del menú contextual sota el llistat de persones i sales i del icona "+".<br />
A la pàgina de paràmetres de la sala es pot:<br />
<br />
* decidir si la sala és pública o privada. Fer-la pública permet a persones accedir-les com a invitades sense que siguin membres.<br />
* decidir si la sala es xifrada o no<br />
* donar una direcció a la sala de tipus #MI_SALA:matrix.org (necessari per poder afegir-la a una comunitat)<br />
* gestionar els drets del membres.<br />
<br />
Per les sales on es volen donar els drets d'admin a tots els membres per defecte, anar les preferencies de la sala, triar la pestanya rols i permisos i posar que el rol per defecte de membre nous és admin.<br />
Aquesta operació és reversible en qualsevol moment. Si es torna a l'opció per defecte (restricted), els membres de la sala tornant a tenir el rol que tenien abans del canvi. Si hi ha membres que van rebre rols d'admin de forma individual, aquests mantindren els seus rols d'admin de forma indiferent al canvi de l'opció per defecte de nous membres.<br />
<br />
'''En resum per poder mantindre el control sobre el rols dels membres i poder banejar:<br />
* no donar rol d'admin a membres de forma individual<br />
* fer servir l'opció d'admin per defecte a nou membres<br />
* si es vol banejar un membre, tornar a posar restricted com a rol per defecte, banejar, i tornar a posar admin com a rol per defecte'''<br />
<br />
==La comunitat de Calafou==<br />
<br />
La comunitat de Calafou permet centralitzar totes les sales actives en relació a les activitats de Calafou.<br />
<br />
En Riot les persones s'identifiquen amb "@", les sales amb "#" i les comunitats amb "+".<br />
<br />
La direcció de la comunitat de calafou és +calafou:matrix.org.<br />
<br />
S'hi pot accedir si la comunitat és pública o per invitació.<br />
<br />
El icona corresponent és el de tres perfils de persones. Clicant aquest icona es llista totes les comunitats de les quals formem part.<br />
Clicant a l'avatar de la comunitat, es filtren les persones a les que formen part de la comunitat.<br />
Clicant el icona "#" apareix el llistat de sales de la comunitat.<br />
<br />
(versió caducada - a més, només els admins poden afegir persones o sales en una comunidad, i només hi ha una persona admin - el ro és intransferrible)<br />
Per afegir una nova sala a la comunitat:<br />
* assegurar-se que la sala té una direcció (veure crear una nova sala)<br />
* fer clic al icona "#" per llistar les sales<br />
* fer clic a afegir una sala<br />
* introduir la direcció de la sala</div>Geotyrhttp://wiki.calafou.org//index.php?title=Per_a_madrines_i_amadrinades&diff=3914Per a madrines i amadrinades2020-07-06T10:27:27Z<p>Geotyr: /* Serveis */ canvi de omnius a essu i afegir nextcloud</p>

<div>==La Madrina==<br />
<br />
Les funcions de les madrines són<br />
* facilitar la integració, l'arribada i la comunicació<br />
* ser el canal receptor de les crítiques en cas que no hi hagi comunicació directa<br />
* acompanyar a la persona en cas de conflicte, de manca de participació, de veus crítiques<br />
* acompanyar per les propostes i peticions, acompanyar per triar els seus espais, ajudar a crear els vincles socials o de projectes<br />
* estar al cas de les decisions sobre la persona amadrinada<br />
* ajustar el vincle entre la persona i calafou,<br />
* referent amb qui parlar<br />

==Organigrama==<br />
<br />
[[File:CF gob.png|400px]]<br />
<br />
L’assemblea és l'òrgan principal de decisions.<br />
<br />
Poden ser monogràfiques sobre un tema específic, de gestió o emocional. El calendari d’assemblees es decideix cada 4 mesos a l’assemblea d’objectius quadrimestrals.<br />
<br />
Les àrees de gestió permeten repartir les gestions per temàtica. Cada àrea defineix els seus objectius i calendari i s’encarrega de crear i de participar als grups de treball conseqüents.<br />
<br />
Els grups de treball es formen per respondre a tasques i objectius concrets. Són els espais d’execució o d’acció.<br />
<br />
El regim intern és el paraigua legal de la cooperativa i està en curs de validació.<br />

L’assemblea és l'òrgan principal de decisions.<br />
<br />
Poden ser monogràfiques sobre un tema especific, de gestió o emocional. El calendari d’assemblees es decideix cada 4 mesos a l’assemblea d’objectius quadrimestrals.<br />
<br />
Les àrees de gestió permeten repartir les gestions per temàtica. Cada àrea defineix els seus objectius i calendari i s’encarrega de crear i de participar als grups de treball conseqüents.<br />
<br />
Els grups de treball es formen per respondre a tasques i objectius concrets. Són els espais d’execució o d’acció.<br />

Les àrees de gestió permeten repartir les gestions per temàtica. Cada àrea defineix els seus objectius i calendari i s’encarrega de crear i de participar als grups de treball conseqüents.<br />
<br />
Els grups de treball es formen per respondre a tasques i objectius concrets. Són els espais d’execució o d’acció.<br />

<hr />
<div>==Tutorial Per Instal·lar Riot==<br />
===Linux Mint===<br />
<br />
Primer he de saber quina versió de Linux Mint estic fent servir.<br />
Per aconseguir-ho cerco a Menú/Preferències/Informació del sistema<br />
<br />
En el meu cas és: Linux Mint 18.2<br />
<br />
Després vaig a veure en quina versió d'Ubuntu està basada. Ho puc veure a:<br />
<br />
https://en.wikipedia.org/wiki/Linux_Mint_version_history<br />
<br />
En el meu cas la versió 18.2, és la que du de nom en codi "Sonya" i està basada en ubuntu 16.04 de nom en codi "Xenial Xerus".<br />
<br />
Ara ja puc seguir el tutorial web:<br />
<br />
https://linuxconfig.org/install-riot-matrix-chat-client-on-debian-and-ubuntu<br />
<br />
Al fitxer /etc/apt/sources.list amb permisos de superusuari escric la següent linea:<br />
<br />
deb https://riot.im/packages/debian xenial main<br />
<br />
(ull: escric xenial perquè la meva distribució està basada en xenial, canvia xenial per la teva que has cercat com explica més amunt)<br />
<br />
<br />
Tot seguit em descarrego la clau GPG per a fer servir el repositori amb:<br />
<br />
$ wget https://riot.im/packages/keys/riot.asc<br />
<br />
I la instal·lo amb:<br />
<br />
$ sudo apt-key add riot.asc<br />
<br />
<br />
Ja està tot llest perr a la instal·lació:<br />
<br />
$ sudo apt update<br />
<br />
$ sudo apt install riot-web<br />
<br />
<br />
Si tot ha anat bé trobarem la icona de riot al menu/internet/ cliquem dues vegades i ja està, ens apareix la pàgina inicial de riot.<br />
<br />
===Debian===<br />
<br />
Primer m'assabento de quina versió de debian tinc instal·lada. Ho puc mirar al fitxer /etc/apt/sources.list amb l'ordre:<br />
<br />
$ cat /etc/apt/sources.list<br />
<br />
<br />
En el meu cas és Jessie.<br />
<br />
<br />
Modifico el fitxer /etc/apt/sources.list afegint la linea:<br />
<br />
deb https://riot.im/packages/debian jessie main<br />
<br />
<br />
Tot seguit em descarrego la clau GPG per a fer servir el repositori amb:<br />
<br />
$ wget https://riot.im/packages/keys/riot.asc<br />
<br />
<br />
I la instal·lo amb:<br />
<br />
$ sudo apt-key add riot.asc<br />
<br />
<br />
Ja està tot llest perr a la instal·lació:<br />
<br />
$ sudo apt update<br />
<br />
$ sudo apt install riot-web<br />
<br />
<br />
Si tot ha anat bé trobarem la icona de riot al menu/internet/ cliquem dues vegades i ja està, ens apareix la pàgina inicial de riot.<br />
<br />
===Ubuntu===<br />
<br />
El procés d'instal·lació és el mateix que al Linux Mint si bé és més fàcil mirar la distribució que tenim, només hem de mirar-ho al fitxer /etc/apt/sources.list<br />
<br />
I tot seguit l'editem com s'explica al tutorial per a Linux MInt.<br />
<br />
La resta de passes han de ser les mateixes.<br />
<br />
===Android===<br />
Ens podem descarregar l'app "riot" des del repositori F-Droid.<br />
<br />
Si no tenim el repositori instal·lat ens el podem instal·lar obrint la pàgina web de l'F-Droid:<br />
<br />
https://f-droid.org/<br />
<br />
i clicant allà on diu "DOWNLOAD" des d'un navegador del nostre smartphone Android.<br />
<br />
Una vegada ens hem instal·lat F-Droid. Actualitzem el repositori i cerquem i instal·lem riot seguint les instruccions de l'aplicació.<br />
<br />
==Registrar-se a Riot==<br />
<br />
Una volta hem arrencar l'aplicació a la part superior esquerra ens apareixen la opció registrar-se, cliquem i s'ens obre una finestra que ens demana mail, telefon, pais del telefon, nom d'usuari i contrasenya. Sembla que només el nom d'usuari i la contrasenya és obligat. Tanmateix si li poses el mail i el telefon els teus amics et podran trobar per ells i també pel teu nom d'usuari.<br />
<br />
Jo li he posat el nom la contrasenya i el mail, quan he clicat a registrar m'ha enviat un mail en el qual he de clicar en l'enllaç que em diu i ja estic registrat.<br />
<br />
<br />
==Accedir a la sala de Calafou==<br />
<br />
Has rebre un mail d'algú que ja hi sigui aconvidant-te.<br />
Quan rebis el mail trobaràs un enllaç per activar el grup. Clica'l. Se t'obrirà al navegador la interfície de riot, logueget a la interficie i llavors torna a clicar l'enllaç del mail. Et demanarà si vols activar el grup cliques que si i ja el tens. Marque'l com a preferit i ja està a disfrutar.<br />
<br />
==Crear una nova sala==<br />
<br />
Les noves sales es creen a partir del menú contextual sota el llistat de persones i sales i del icona "+".<br />
A la pàgina de paràmetres de la sala es pot:<br />
<br />
* decidir si la sala és pública o privada. Fer-la pública permet a persones accedir-les com a invitades sense que siguin membres.<br />
* decidir si la sala es xifrada o no<br />
* donar una direcció a la sala de tipus #MI_SALA:matrix.org (necessari per poder afegir-la a una comunitat)<br />
* gestionar els drets del membres.<br />
<br />
Per les sales on es volen donar els drets d'admin a tots els membres per defecte, anar les preferencies de la sala, triar la pestanya rols i permisos i posar que el rol per defecte de membre nous és admin.<br />
Aquesta operació és reversible en qualsevol moment. Si es torna a l'opció per defecte (restricted), els membres de la sala tornant a tenir el rol que tenien abans del canvi. Si hi ha membres que van rebre rols d'admin de forma individual, aquests mantindren els seus rols d'admin de forma indiferent al canvi de l'opció per defecte de nous membres.<br />
<br />
'''En resum per poder mantindre el control sobre el rols dels membres i poder banejar:<br />
* no donar rol d'admin a membres de forma individual<br />
* fer servir l'opció d'admin per defecte a nou membres<br />
* si es vol banejar un membre, tornar a posar restricted com a rol per defecte, banejar, i tornar a posar admin com a rol per defecte'''<br />
<br />
==La comunitat de Calafou==<br />
<br />
La comunitat de Calafou permet centralitzar totes les sales actives en relació a les activitats de Calafou.<br />
<br />
En Riot les persones s'identifiquen amb "@", les sales amb "#" i les comunitats amb "+".<br />
<br />
La direcció de la comunitat de calafou és +calafou:matrix.org.<br />
<br />
S'hi pot accedir si la comunitat és pública o per invitació.<br />
<br />

<div>Bookscanning in Calafou:<br />
<br />
* We made an event called Hack the Biblio: Let's make Digital Public Libraries in 2014 as a collaboration with memoryoftheworld, when Voja Antonic donated a bookscanner to Calafou: https://calafou.org/en/content/hack-biblio-construir-bibliotecas-publicas https://calafou.org/en/content/voja-antonic-calafou<br />
* We scan out of print books published by Virus: http://www.viruseditorial.net/<br />

<br />
= Building a "New Standard Scanner" =<br />
<br />
We built this: https://forum.diybookscanner.org/viewtopic.php?f=1&t=333 during the Kunlabora event in Calafou: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative A more reproducible and portable and simple scanner.<br />
<br />
In theory for the simple scanner it should be possible to get all the ingredients from a hardware shop ("ferreteria"). We got most of the materials from Bauhaus in Barcelona (Zona Franca). Our experience was that most of the screws, nuts and bolts are easy to substitute with others that have more or less the same dimensions.<br />
<br />

<br />
== Budget ==<br />
<br />
Kunlabora event was four days of collaborative construction. More or less six persons worked on building the scanner. This is the receipts that we spent, because we had 500 EUR budget for the raw materials from the participation fee of the event. <br />
<br />
Receipts:<br />
<br />
25 2x plexiglass [J] @ Expocryl, Igualada<br />
18 2x SD cards @ Life Informatica, Barcelona<br />
50 2x magic want camera stand @ FotoK, Barcelona<br />

108.8 Nuts/bolts/etc. @ Bauhaus, Zona Franca, Barcelona<br />
10 2x USB cable male/female @ Worten San Antoni, Barcelona<br />
5 2x mini USB (USB-B) cable @ Tienda Cables, Barcelona<br />
178 2x Canon IXUS 175 compact digital camera @ Amazon.es<br />
60 4x Wooden beams (listones) @ Fustes Fargas, Barcelona<br />
============================================<br />
497<br />
<br />
Donations:<br />
<br />
70 Raspberry Pi 3 (Model B), 2x SD cards, 5V charger, rulers [M] @ Barcelona<br />
<br />
We also used nuts and bolts, etc. found in the workshop of Calafou (in Catalunya, near Barcelona). The conclusion is that it should be possible to build this scanner from about 5-600 EUR anywhere in (Western) Europe. We did not use all the materials we bought and if we would do it again then we tried to use real wood instead of FDM, because the latter proved very fragile. However, this could make the platen more heavy, and it is already quite heavy.<br />

<b>Things to take in consideration from the building experience</b><br />
<br />
* the MDF pieces are fragile and gave us problems when introducing screws<br />
* we considered varnishing the wood pieces to limit humidity impact<br />
* the plexiglas we bought generates many reflections<br />
* passing from inches to cm was uncomfortable<br />
* the position and height of the light should be tested before being fixed<br />
* the upper part of the light stand should be easier to mount and unmount for transportation<br />
* the wood used for the platen should be without texture or painted with mate dark paint<br />
* the gooseneck (Manfrotto) option for the camera stand is not a good option: it is very easy to put the camera in the way of the cradle; the calibration process is difficult because the cameras can move in the three axis; they are springy and difficult to set in an exact position<br />
<br />
== Cameras ==<br />
<br />
The bookscanner is basically a glorified camera stand that allows us to take good pictures of book pages. So the cameras are an important part of the bookscanner. Summary of research about cameras for book scanners:<br />
<br />
Basically there are three categories of cameras that can be used for book scanners (from cheapest to most expensive).<br />
<br />
1. Remote control support<br />
<br />
The cheapest option is any camera with remote trigger support, so we can take pictures without pushing the button on the camera. This is important because when you press the button the camera position may be disadjusted to the physical pressure.<br />
<br />
2. CHDK firmware<br />
<br />
Middle category is CHDK firmware compatibles. CHDK is a third party open source firmware that allows the customisation of cameras. CHDK firmware is for Canon Powershot cameras, which are the cheaper compact digital camera product line. We have 200 euros in the budget for cameras, so we went with this option.<br />
<br />
3. Magic Lantern support<br />
<br />
Magic Lantern is a third party open source firmware that is more advanced. However, it only works with Canon DLSR cameras (these are the cameras that have a reflex mirror to look at the shot through a small hole before you take the picture, and they usually have big lenses). The scanner we have now uses Canon 1100D, which are the cheapest type suported by Magic Lantern, but they still cost a few hundred euros.<br />
<br />
4. Connecting to a monitor<br />
<br />
It is very useful to be able to connect the cameras to a monitor during the calibration process. The cameras we bought use the same output for connecting to a remote control and to a monitor making it not practical at all using a monitor. Furthermore, connection with usb to a computer monitor was not an option, we had to look for RC connectors or adapters.<br />
<br />
5. Webcams<br />
<br />
Another option would be to use two high resolution webcams directly connected to a laptop to trigger taking pictures and monitor their quality.<br />
<br />
== Building process ==<br />
<br />
=== Base / Base ===<br />
<br />
[[File:02 BASE 035.JPG|500px|none|left]]<br />
[[File:02 BASE 043.JPG|500px|none|left]]<br />
[[File:02 BASE 040.JPG|500px|none|left]]<br />
We cut the wood beams to have 2 pieces of 56x4cm and 2 of 31.5x4cm<br />
<br />
[[File:02 BASE 044.JPG|500px|none|left]]<br />
[[File:02 BASE 041.JPG|500px|none|left]]<br />
we measured with precision tools and marked the position of the drawer sliders on the 54x4cm wood beams <br />
<br />
[[File:02 BASE 045.JPG|500px|none|left]]<br />
we drilled holes on the marked position<br />
<br />
[[File:02 BASE 049.JPG|500px|none|left]]<br />
[[File:02 BASE 050.JPG|500px|none|left]]<br />
[[File:02 BASE 051.JPG|500px|none|left]]<br />
and then we fixed the sliders<br />
<br />
[[File:02 BASE 033.JPG|500px|none|left]]<br />
We used the thicker MDF material to cut a 37x29cm sheet<br />
<br />
[[File:02 BASE 056.JPG|500px|none|left]]<br />
The last parts were fixing the other part of the sliders to the MDF sheet and attaching the different part of the base with screws<br />
<br />
<br />
=== Cradle / Cuna ===<br />
The cradle is a V-shaped book holder partly fixed to the base<br />
[[File:07 GEN 036.JPG|500px|none|left]]<br />
We cut two MDF (thin) sheets for the book holder<br />
<br />
[[File:03 CRADDLE 037.JPG|500px|none|left]]<br />
[[File:03 CRADDLE 046.JPG|500px|none|left]]<br />
And 4 small triangles to maintain the book holder on the base with a 90 degree angle between both sheets<br />
[[File:03 CRADDLE 057.JPG|500px|none|left]]<br />
We measured were to position the triangles<br />
[[File:03 CRADDLE 071.JPG|500px|none|left]]<br />
Drilled the MDF sheet on the base<br />
[[File:03 CRADDLE 058.JPG|500px|none|left]]<br />
And fixed the MDF small triangles<br />
<br />
[[File:03 CRADDLE 059.JPG|500px|none|left]]<br />
We drilled the MDF sheet of the Craddle<br />
[[File:03 CRADDLE 061.JPG|500px|none|left]]<br />
And fixed it to the triangles<br />
<br />
NOT DOCUMENTED WITH PICTURES<br />
[[File:05 COLUMN 066.JPG|500px|none|left]]<br />
The 2 other triangles were fixed to the other MDF sheet without being fixed to the base.<br />
The distance between the triangles is of 19.5cm.<br />
We cut a 19.5x19.5cm MDF square that we attached to the other side of the base.<br />
The drilled the 2 triangles in order to introduce a threaded rod.<br />
The threaded rod is used to tighten the triangles against the square fixed on the base. <br />

= Raspberry Pi for the bookscanner =<br />
<br />
At the moment we use an electromechanical button documented on the CHDK website that works well but does not do much more than triggering the two cameras to shoot at the same time: http://chdk.wikia.com/wiki/USB_Remote<br />
<br />
There are many more possibilities of how to optimise the bookscanning process. Many ideas start with connecting the cameras to a small computer such as the Raspberry Pi. We made some experiments and tests with this setup, which is documented below:<br />
<br />
It runs [https://www.raspbian.org/ Raspbian].<br />
<br />
== CHDKPTP ==<br />
<br />
In /home/pi/chdkptp there are precompiled binaries of [https://app.assembla.com/spaces/chdkptp/wiki CHDKPTP] downloaded from [https://app.assembla.com/spaces/chdkptp/documents here].<br />
<br />
CHDKPTP is used for remote control of camera running CHDK firmware.<br />
<br />
Our setup has two modes of work:<br />
* mechanical "button" which triggers both camera capturing its photo based on this tutorial: http://chdk.wikia.com/wiki/USB_Remote<br />
* (in progress) Raspberry Pi mode where an bookscanner operator uses Raspberry Pi to capture photos, preview photos in real time and transfer them already renamed for the next step in Scantailor.<br />
<br />
When camera is connected this line will list info about the camera e.g.:<br />
<nowiki>sudo ./chdkptp.sh -elist</nowiki><br />
and for one of the camera this is what is listed then:<br />
<nowiki>-1:Canon IXUS 175 b=001 d=030 v=0x4a9 p=0x32c1 s=8B20D62641B041BAA3E1D597D560D110</nowiki><br />
<br />
An example of capturing a picture from commandline (once in /home/pi/chdkptp/):<br />
<nowiki>sudo ./chdkptp.sh -e"connect -d=030" -erec -eshoot</nowiki><br />
Above line connects to the camera sitting on -d=021, puts it into rec mode (if not already) and capture the photo saving it to SD card already in camera. If one wants to bypass the SD card altogether it should replace -eshoot with -eremoteshoot. In that case ./chdkptp.sh will save photos into the directory from where it was called.<br />
<br />
Note: check the SD card is locked.<br />
<br />
== ZeroTier ==<br />
<br />
It is added to 565799d8f6ebf1a8 public network of [https://zerotier.com ZeroTier] with this command:<br />
<nowiki>sudo zerotier-cli join 565799d8f6ebf1a8</nowiki><br />
and it got static IP address (in 565799d8f6ebf1a8 network):<br />
<nowiki>192.168.192.171/24</nowiki><br />
<br />
In /home/pi/.ssh/authorized_keys public keys of maxigas and marcell are added.<br />
<br />
= Ideas for building Voja's scanner =<br />
<br />
Our first idea was to reproduce Voja's scanner but we had to realise that we are not Voja and the scanner is very beautiful and unique engineering and consequently it is hard to reproduce. <br />
<br />
Here are two links to the public documentation of our scanner, built by Voja Antonic:<br />
<br />
https://www.memoryoftheworld.org/blog/2012/10/28/our-beloved-bookscanner-2/<br />
<br />
https://hackaday.io/project/5604-diy-book-scanner<br />
<br />
The electronics is not really documented (which means that it is hard to reproduce) and it is built from basic parts (which means that it takes a lot of time to put it together). So we brainstorm about an Arduino-based solution instead. Arduino is a general-purpose programmable microcontroller that has already built-in many of the functions/parts we need. The idea is that this makes it easier for us to build the scanner and for others to reproduce it. We also have more experience working with Arduino than with only basic electronic components. <br />
<br />
We will also try to use cheaper cameras in order to bring down the budget.<br />

* We made an event called Hack the Biblio: Let's make Digital Public Libraries in 2014 as a collaboration with memoryoftheworld, when Voja Antonic donated a bookscanner to Calafou: https://calafou.org/en/content/hack-biblio-construir-bibliotecas-publicas https://calafou.org/en/content/voja-antonic-calafou<br />

= Building a "New Standard Scanner" =<br />
<br />
We built this: https://forum.diybookscanner.org/viewtopic.php?f=1&t=333 during the Kunlabora event in Calafou: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative A more reproducible and portable and simple scanner.<br />
<br />
In theory for the simple scanner it should be possible to get all the ingredients from a hardware shop ("ferreteria"). We got most of the materials from Bauhaus in Barcelona (Zona Franca). Our experience was that most of the screws, nuts and bolts are easy to substitute with others that have more or less the same dimensions.<br />
<br />
[[File:bookscanner_pseudoready2.jpg|600px]] <br />
<br />
== Budget ==<br />
<br />
Kunlabora event was four days of collaborative construction. More or less six persons worked on building the scanner. This is the receipts that we spent, because we had 500 EUR budget for the raw materials from the participation fee of the event. <br />
<br />
Receipts:<br />
<br />
25 2x plexiglass [J] @ Expocryl, Igualada<br />
18 2x SD cards @ Life Informatica, Barcelona<br />
50 2x magic want camera stand @ FotoK, Barcelona<br />

<br />
We also used nuts and bolts, etc. found in the workshop of Calafou (in Catalunya, near Barcelona). The conclusion is that it should be possible to build this scanner from about 5-600 EUR anywhere in (Western) Europe. We did not use all the materials we bought and if we would do it again then we tried to use real wood instead of FDM, because the latter proved very fragile. However, this could make the platen more heavy, and it is already quite heavy.<br />

<b>Things to take in consideration from the building experience</b><br />
<br />
* the MDF pieces are fragile and gave us problems when introducing screws<br />
* we considered varnishing the wood pieces to limit humidity impact<br />
* the plexiglas we bought generates many reflections<br />
* passing from inches to cm was uncomfortable<br />
* the position and height of the light should be tested before being fixed<br />
* the upper part of the light stand should be easier to mount and unmount for transportation<br />
* the wood used for the platen should be without texture or painted with mate dark paint<br />
* the gooseneck (Manfrotto) option for the camera stand is not a good option: it is very easy to put the camera in the way of the cradle; the calibration process is difficult because the cameras can move in the three axis; they are springy and difficult to set in an exact position<br />
<br />
== Cameras ==<br />
<br />
The bookscanner is basically a glorified camera stand that allows us to take good pictures of book pages. So the cameras are an important part of the bookscanner. Summary of research about cameras for book scanners:<br />
<br />
Basically there are three categories of cameras that can be used for book scanners (from cheapest to most expensive).<br />
<br />
1. Remote control support<br />
<br />
The cheapest option is any camera with remote trigger support, so we can take pictures without pushing the button on the camera. This is important because when you press the button the camera position may be disadjusted to the physical pressure.<br />
<br />
2. CHDK firmware<br />
<br />
Middle category is CHDK firmware compatibles. CHDK is a third party open source firmware that allows the customisation of cameras. CHDK firmware is for Canon Powershot cameras, which are the cheaper compact digital camera product line. We have 200 euros in the budget for cameras, so we went with this option.<br />
<br />
3. Magic Lantern support<br />
<br />
Magic Lantern is a third party open source firmware that is more advanced. However, it only works with Canon DLSR cameras (these are the cameras that have a reflex mirror to look at the shot through a small hole before you take the picture, and they usually have big lenses). The scanner we have now uses Canon 1100D, which are the cheapest type suported by Magic Lantern, but they still cost a few hundred euros.<br />
<br />
4. Connecting to a monitor<br />
<br />
It is very useful to be able to connect the cameras to a monitor during the calibration process. The cameras we bought use the same output for connecting to a remote control and to a monitor making it not practical at all using a monitor. Furthermore, connection with usb to a computer monitor was not an option, we had to look for RC connectors or adapters.<br />
<br />
== Building process ==<br />
<br />
=== Base / Base ===<br />
<br />
[[File:02 BASE 035.JPG|500px|none|left]]<br />
[[File:02 BASE 043.JPG|500px|none|left]]<br />
[[File:02 BASE 040.JPG|500px|none|left]]<br />
We cut the wood beams to have 2 pieces of 56x4cm and 2 of 31.5x4cm<br />
<br />
[[File:02 BASE 044.JPG|500px|none|left]]<br />
[[File:02 BASE 041.JPG|500px|none|left]]<br />
we measured with precision tools and marked the position of the drawer sliders on the 54x4cm wood beams <br />
<br />
[[File:02 BASE 045.JPG|500px|none|left]]<br />
we drilled holes on the marked position<br />
<br />
[[File:02 BASE 049.JPG|500px|none|left]]<br />
[[File:02 BASE 050.JPG|500px|none|left]]<br />
[[File:02 BASE 051.JPG|500px|none|left]]<br />
and then we fixed the sliders<br />
<br />
[[File:02 BASE 033.JPG|500px|none|left]]<br />
We used the thicker MDF material to cut a 37x29cm sheet<br />
<br />
[[File:02 BASE 056.JPG|500px|none|left]]<br />
The last parts were fixing the other part of the sliders to the MDF sheet and attaching the different part of the base with screws<br />
<br />
<br />
=== Cradle / Cuna ===<br />
The cradle is a V-shaped book holder partly fixed to the base<br />
[[File:07 GEN 036.JPG|500px|none|left]]<br />
We cut two MDF (thin) sheets for the book holder<br />
<br />
[[File:03 CRADDLE 037.JPG|500px|none|left]]<br />
[[File:03 CRADDLE 046.JPG|500px|none|left]]<br />
And 4 small triangles to maintain the book holder on the base with a 90 degree angle between both sheets<br />
[[File:03 CRADDLE 057.JPG|500px|none|left]]<br />
We measured were to position the triangles<br />
[[File:03 CRADDLE 071.JPG|500px|none|left]]<br />
Drilled the MDF sheet on the base<br />
[[File:03 CRADDLE 058.JPG|500px|none|left]]<br />
And fixed the MDF small triangles<br />
<br />
[[File:03 CRADDLE 059.JPG|500px|none|left]]<br />
We drilled the MDF sheet of the Craddle<br />
[[File:03 CRADDLE 061.JPG|500px|none|left]]<br />
And fixed it to the triangles<br />
<br />
NOT DOCUMENTED WITH PICTURES<br />
[[File:05 COLUMN 066.JPG|500px|none|left]]<br />
The 2 other triangles were fixed to the other MDF sheet without being fixed to the base.<br />
The distance between the triangles is of 19.5cm.<br />
We cut a 19.5x19.5cm MDF square that we attached to the other side of the base.<br />
The drilled the 2 triangles in order to introduce a threaded rod.<br />
The threaded rod is used to tighten the triangles against the square fixed on the base. <br />

= Raspberry Pi for the bookscanner =<br />
<br />
At the moment we use an electromechanical button documented on the CHDK website that works well but does not do much more than triggering the two cameras to shoot at the same time: http://chdk.wikia.com/wiki/USB_Remote<br />
<br />
There are many more possibilities of how to optimise the bookscanning process. Many ideas start with connecting the cameras to a small computer such as the Raspberry Pi. We made some experiments and tests with this setup, which is documented below:<br />
<br />
It runs [https://www.raspbian.org/ Raspbian].<br />
<br />
== CHDKPTP ==<br />
<br />
In /home/pi/chdkptp there are precompiled binaries of [https://app.assembla.com/spaces/chdkptp/wiki CHDKPTP] downloaded from [https://app.assembla.com/spaces/chdkptp/documents here].<br />
<br />
CHDKPTP is used for remote control of camera running CHDK firmware.<br />
<br />
Our setup has two modes of work:<br />
* mechanical "button" which triggers both camera capturing its photo based on this tutorial: http://chdk.wikia.com/wiki/USB_Remote<br />
* (in progress) Raspberry Pi mode where an bookscanner operator uses Raspberry Pi to capture photos, preview photos in real time and transfer them already renamed for the next step in Scantailor.<br />
<br />
When camera is connected this line will list info about the camera e.g.:<br />
<nowiki>sudo ./chdkptp.sh -elist</nowiki><br />
and for one of the camera this is what is listed then:<br />
<nowiki>-1:Canon IXUS 175 b=001 d=030 v=0x4a9 p=0x32c1 s=8B20D62641B041BAA3E1D597D560D110</nowiki><br />
<br />
An example of capturing a picture from commandline (once in /home/pi/chdkptp/):<br />
<nowiki>sudo ./chdkptp.sh -e"connect -d=030" -erec -eshoot</nowiki><br />
Above line connects to the camera sitting on -d=021, puts it into rec mode (if not already) and capture the photo saving it to SD card already in camera. If one wants to bypass the SD card altogether it should replace -eshoot with -eremoteshoot. In that case ./chdkptp.sh will save photos into the directory from where it was called.<br />
<br />
Note: check the SD card is locked.<br />
<br />
== ZeroTier ==<br />
<br />
It is added to 565799d8f6ebf1a8 public network of [https://zerotier.com ZeroTier] with this command:<br />
<nowiki>sudo zerotier-cli join 565799d8f6ebf1a8</nowiki><br />
and it got static IP address (in 565799d8f6ebf1a8 network):<br />
<nowiki>192.168.192.171/24</nowiki><br />
<br />
In /home/pi/.ssh/authorized_keys public keys of maxigas and marcell are added.<br />
<br />
= Ideas for building Voja's scanner =<br />
<br />
Our first idea was to reproduce Voja's scanner but we had to realise that we are not Voja and the scanner is very beautiful and unique engineering and consequently it is hard to reproduce. <br />
<br />
Here are two links to the public documentation of our scanner, built by Voja Antonic:<br />
<br />
https://www.memoryoftheworld.org/blog/2012/10/28/our-beloved-bookscanner-2/<br />
<br />
https://hackaday.io/project/5604-diy-book-scanner<br />
<br />
The electronics is not really documented (which means that it is hard to reproduce) and it is built from basic parts (which means that it takes a lot of time to put it together). So we brainstorm about an Arduino-based solution instead. Arduino is a general-purpose programmable microcontroller that has already built-in many of the functions/parts we need. The idea is that this makes it easier for us to build the scanner and for others to reproduce it. We also have more experience working with Arduino than with only basic electronic components. <br />
<br />
We will also try to use cheaper cameras in order to bring down the budget.<br />

<div>Bookscanning in Calafou:<br />
<br />
* We made an event called Hack the Biblio: Let's make Digital Public Libraries in 2014 as a collaboration with memoryoftheworld, when Voja Antonic donated a bookscanner to Calafou: https://calafou.org/en/content/hack-biblio-construir-bibliotecas-publicas https://calafou.org/en/content/voja-antonic-calafou<br />
* We scan out of print books published by Virus: http://www.viruseditorial.net/<br />

<br />
This page is documenting the design and construction of bookscanners. For the tutorial that explains "How to use the bookscanner", go to http://wiki.calafou.org/index.php/Bookscanning<br />
<br />
= Building a "New Standard Scanner" =<br />
<br />
We built this: https://forum.diybookscanner.org/viewtopic.php?f=1&t=333 during the Kunlabora event in Calafou: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative A more reproducible and portable and simple scanner.<br />
<br />
In theory for the simple scanner it should be possible to get all the ingredients from a hardware shop ("ferreteria"). We got most of the materials from Bauhaus in Barcelona (Zona Franca). Our experience was that most of the screws, nuts and bolts are easy to substitute with others that have more or less the same dimensions.<br />
<br />
[[File:bookscanner_pseudoready2.jpg|600px]] <br />
<br />
== Budget ==<br />
<br />
Kunlabora event was four days of collaborative construction. More or less six persons worked on building the scanner. This is the receipts that we spent, because we had 500 EUR budget for the raw materials from the participation fee of the event. <br />
<br />
Receipts:<br />
<br />
25 2x plexiglass [J] @ Expocryl, Igualada<br />
18 2x SD cards @ Life Informatica, Barcelona<br />
50 2x magic want camera stand @ FotoK, Barcelona<br />
42.2 Nuts/bolts/etc. @ Bauhaus, Zona Franca, Barcelona<br />
108.8 Nuts/bolts/etc. @ Bauhaus, Zona Franca, Barcelona<br />
10 2x USB cable male/female @ Worten San Antoni, Barcelona<br />
5 2x mini USB (USB-B) cable @ Tienda Cables, Barcelona<br />
178 2x Canon IXUS 175 compact digital camera @ Amazon.es<br />
60 4x Wooden beams (listones) @ Fustes Fargas, Barcelona<br />
============================================<br />
497<br />
<br />
Donations:<br />
<br />
70 Raspberry Pi 3 (Model B), 2x SD cards, 5V charger, rulers [M] @ Barcelona<br />
<br />
We also used nuts and bolts, etc. found in the workshop of Calafou (in Catalunya, near Barcelona). The conclusion is that it should be possible to build this scanner from about 5-600 EUR anywhere in (Western) Europe. We did not use all the materials we bought and if we would do it again then we tried to use real wood instead of FDM, because the latter proved very fragile. However, this could make the platen more heavy, and it is already quite heavy.<br />

<br />
== Cameras ==<br />
<br />
The bookscanner is basically a glorified camera stand that allows us to take good pictures of book pages. So the cameras are an important part of the bookscanner. Summary of research about cameras for book scanners:<br />
<br />
Basically there are three categories of cameras that can be used for book scanners (from cheapest to most expensive).<br />
<br />
1. Remote control support<br />
<br />
The cheapest option is any camera with remote trigger support, so we can take pictures without pushing the button on the camera. This is important because when you press the button the camera position may be disadjusted to the physical pressure.<br />
<br />
2. CHDK firmware<br />
<br />
Middle category is CHDK firmware compatibles. CHDK is a third party open source firmware that allows the customisation of cameras. CHDK firmware is for Canon Powershot cameras, which are the cheaper compact digital camera product line. We have 200 euros in the budget for cameras, so we went with this option.<br />
<br />
3. Magic Lantern support<br />
<br />
Magic Lantern is a third party open source firmware that is more advanced. However, it only works with Canon DLSR cameras (these are the cameras that have a reflex mirror to look at the shot through a small hole before you take the picture, and they usually have big lenses). The scanner we have now uses Canon 1100D, which are the cheapest type suported by Magic Lantern, but they still cost a few hundred euros.<br />
<br />
4. Connecting to a monitor<br />
<br />
It is very useful to be able to connect the cameras to a monitor during the calibration process. The cameras we bought use the same output for connecting to a remote control and to a monitor making it not practical at all using a monitor. Furthermore, connection with usb to a computer monitor was not an option, we had to look for RC connectors or adapters.<br />

[[File:02 BASE 043.JPG|500px|none|left]]<br />
[[File:02 BASE 040.JPG|500px|none|left]]<br />
We cut the wood beams to have 2 pieces of 56x4cm and 2 of 31.5x4cm<br />
<br />
[[File:02 BASE 044.JPG|500px|none|left]]<br />
[[File:02 BASE 041.JPG|500px|none|left]]<br />
we measured with precision tools and marked the position of the drawer sliders on the 54x4cm wood beams <br />
<br />
[[File:02 BASE 045.JPG|500px|none|left]]<br />
we drilled holes on the marked position<br />

and then we fixed the sliders<br />
<br />
[[File:02 BASE 033.JPG|500px|none|left]]<br />
We used the thicker MDF material to cut a 37x29cm sheet<br />
<br />
[[File:02 BASE 056.JPG|500px|none|left]]<br />
The last parts were fixing the other part of the sliders to the MDF sheet and attaching the different part of the base with screws<br />
<br />
<br />
=== Cradle / Cuna ===<br />
The cradle is a V-shaped book holder partly fixed to the base<br />
[[File:07 GEN 036.JPG|500px|none|left]]<br />
We cut two MDF (thin) sheets for the book holder<br />
<br />
[[File:03 CRADDLE 037.JPG|500px|none|left]]<br />
[[File:03 CRADDLE 046.JPG|500px|none|left]]<br />
And 4 small triangles to maintain the book holder on the base with a 90 degree angle between both sheets<br />
[[File:03 CRADDLE 057.JPG|500px|none|left]]<br />
We measured were to position the triangles<br />
[[File:03 CRADDLE 071.JPG|500px|none|left]]<br />
Drilled the MDF sheet on the base<br />
[[File:03 CRADDLE 058.JPG|500px|none|left]]<br />
And fixed the MDF small triangles<br />
<br />
[[File:03 CRADDLE 059.JPG|500px|none|left]]<br />
We drilled the MDF sheet of the Craddle<br />
[[File:03 CRADDLE 061.JPG|500px|none|left]]<br />
And fixed it to the triangles<br />
<br />
NOT DOCUMENTED WITH PICTURES<br />
[[File:05 COLUMN 066.JPG|500px|none|left]]<br />
The 2 other triangles were fixed to the other MDF sheet without being fixed to the base.<br />
The distance between the triangles is of 19.5cm.<br />
We cut a 19.5x19.5cm MDF square that we attached to the other side of the base.<br />
The drilled the 2 triangles in order to introduce a threaded rod.<br />
The threaded rod is used to tighten the triangles against the square fixed on the base. <br />

= Raspberry Pi for the bookscanner =<br />
<br />
At the moment we use an electromechanical button documented on the CHDK website that works well but does not do much more than triggering the two cameras to shoot at the same time: http://chdk.wikia.com/wiki/USB_Remote<br />
<br />
There are many more possibilities of how to optimise the bookscanning process. Many ideas start with connecting the cameras to a small computer such as the Raspberry Pi. We made some experiments and tests with this setup, which is documented below:<br />
<br />
It runs [https://www.raspbian.org/ Raspbian].<br />
<br />
== CHDKPTP ==<br />
<br />
In /home/pi/chdkptp there are precompiled binaries of [https://app.assembla.com/spaces/chdkptp/wiki CHDKPTP] downloaded from [https://app.assembla.com/spaces/chdkptp/documents here].<br />
<br />
CHDKPTP is used for remote control of camera running CHDK firmware.<br />
<br />
Our setup has two modes of work:<br />
* mechanical "button" which triggers both camera capturing its photo based on this tutorial: http://chdk.wikia.com/wiki/USB_Remote<br />
* (in progress) Raspberry Pi mode where an bookscanner operator uses Raspberry Pi to capture photos, preview photos in real time and transfer them already renamed for the next step in Scantailor.<br />
<br />
When camera is connected this line will list info about the camera e.g.:<br />
<nowiki>sudo ./chdkptp.sh -elist</nowiki><br />
and for one of the camera this is what is listed then:<br />
<nowiki>-1:Canon IXUS 175 b=001 d=030 v=0x4a9 p=0x32c1 s=8B20D62641B041BAA3E1D597D560D110</nowiki><br />
<br />
An example of capturing a picture from commandline (once in /home/pi/chdkptp/):<br />
<nowiki>sudo ./chdkptp.sh -e"connect -d=030" -erec -eshoot</nowiki><br />
Above line connects to the camera sitting on -d=021, puts it into rec mode (if not already) and capture the photo saving it to SD card already in camera. If one wants to bypass the SD card altogether it should replace -eshoot with -eremoteshoot. In that case ./chdkptp.sh will save photos into the directory from where it was called.<br />
<br />
Note: check the SD card is locked.<br />
<br />
== ZeroTier ==<br />
<br />
It is added to 565799d8f6ebf1a8 public network of [https://zerotier.com ZeroTier] with this command:<br />
<nowiki>sudo zerotier-cli join 565799d8f6ebf1a8</nowiki><br />
and it got static IP address (in 565799d8f6ebf1a8 network):<br />
<nowiki>192.168.192.171/24</nowiki><br />
<br />
In /home/pi/.ssh/authorized_keys public keys of maxigas and marcell are added.<br />
<br />
= Ideas for building Voja's scanner =<br />
<br />
Our first idea was to reproduce Voja's scanner but we had to realise that we are not Voja and the scanner is very beautiful and unique engineering and consequently it is hard to reproduce. <br />
<br />
Here are two links to the public documentation of our scanner, built by Voja Antonic:<br />
<br />
https://www.memoryoftheworld.org/blog/2012/10/28/our-beloved-bookscanner-2/<br />
<br />
https://hackaday.io/project/5604-diy-book-scanner<br />
<br />
The electronics is not really documented (which means that it is hard to reproduce) and it is built from basic parts (which means that it takes a lot of time to put it together). So we brainstorm about an Arduino-based solution instead. Arduino is a general-purpose programmable microcontroller that has already built-in many of the functions/parts we need. The idea is that this makes it easier for us to build the scanner and for others to reproduce it. We also have more experience working with Arduino than with only basic electronic components. <br />
<br />
We will also try to use cheaper cameras in order to bring down the budget.<br />

<div>Bookscanning in Calafou:<br />
<br />
* We made an event called Hack the Biblio: Let's make Digital Public Libraries in 2014 as a collaboration with memoryoftheworld, when Voja Antonic donated a bookscanner to Calafou: https://calafou.org/en/content/hack-biblio-construir-bibliotecas-publicas https://calafou.org/en/content/voja-antonic-calafou<br />
* We scan out of print books published by Virus: http://www.viruseditorial.net/<br />
* <span style='width:32em;font-size:18px;font-weight:light;font-family:Courier,Sans;display:block;padding:4px;background:#DAA520;color:black;'>marron_scanner 😎 </span> was built in 2018 during the Kunlabora event for supporting other collectives that want to scan: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative<br />
<br />
This page is documenting the design and construction of bookscanners. For the tutorial that explains "How to use the bookscanner", go to http://wiki.calafou.org/index.php/Bookscanning<br />
<br />
= Building a "New Standard Scanner" =<br />
<br />
We built this: https://forum.diybookscanner.org/viewtopic.php?f=1&t=333 during the Kunlabora event in Calafou: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative A more reproducible and portable and simple scanner.<br />
<br />
In theory for the simple scanner it should be possible to get all the ingredients from a hardware shop ("ferreteria"). We got most of the materials from Bauhaus in Barcelona (Zona Franca). Our experience was that most of the screws, nuts and bolts are easy to substitute with others that have more or less the same dimensions.<br />
<br />
[[File:bookscanner_pseudoready2.jpg|600px]] <br />
<br />
== Budget ==<br />
<br />
Kunlabora event was four days of collaborative construction. More or less six persons worked on building the scanner. This is the receipts that we spent, because we had 500 EUR budget for the raw materials from the participation fee of the event. <br />
<br />
Receipts:<br />
<br />
25 2x plexiglass [J] @ Expocryl, Igualada<br />
18 2x SD cards @ Life Informatica, Barcelona<br />
50 2x magic want camera stand @ FotoK, Barcelona<br />

5 2x mini USB (USB-B) cable @ Tienda Cables, Barcelona<br />
178 2x Canon IXUS 175 compact digital camera @ Amazon.es<br />
60 4x Wooden beams (listones) @ Fustes Fargas, Barcelona<br />

497<br />
<br />
Donations:<br />
<br />
70 Raspberry Pi 3 (Model B), 2x SD cards, 5V charger, rulers [M] @ Barcelona<br />
<br />
We also used nuts and bolts, etc. found in the workshop of Calafou (in Catalunya, near Barcelona). The conclusion is that it should be possible to build this scanner from about 5-600 EUR anywhere in (Western) Europe. We did not use all the materials we bought and if we would do it again then we tried to use real wood instead of FDM, because the latter proved very fragile. However, this could make the platen more heavy, and it is already quite heavy.<br />

CHDKPTP is used for remote control of camera running CHDK firmware.<br />
<br />
Our setup has two modes of work:<br />
* mechanical "button" which triggers both camera capturing its photo based on this tutorial: http://chdk.wikia.com/wiki/USB_Remote<br />
* (in progress) Raspberry Pi mode where an bookscanner operator uses Raspberry Pi to capture photos, preview photos in real time and transfer them already renamed for the next step in Scantailor.<br />
<br />
When camera is connected this line will list info about the camera e.g.:<br />
<nowiki>sudo ./chdkptp.sh -elist</nowiki><br />
and for one of the camera this is what is listed then:<br />
<nowiki>-1:Canon IXUS 175 b=001 d=030 v=0x4a9 p=0x32c1 s=8B20D62641B041BAA3E1D597D560D110</nowiki><br />
<br />
An example of capturing a picture from commandline (once in /home/pi/chdkptp/):<br />
<nowiki>sudo ./chdkptp.sh -e"connect -d=030" -erec -eshoot</nowiki><br />
Above line connects to the camera sitting on -d=021, puts it into rec mode (if not already) and capture the photo saving it to SD card already in camera. If one wants to bypass the SD card altogether it should replace -eshoot with -eremoteshoot. In that case ./chdkptp.sh will save photos into the directory from where it was called.<br />
<br />
Note: check the SD card is locked.<br />
<br />
== ZeroTier ==<br />
<br />
It is added to 565799d8f6ebf1a8 public network of [https://zerotier.com ZeroTier] with this command:<br />
<nowiki>sudo zerotier-cli join 565799d8f6ebf1a8</nowiki><br />
and it got static IP address (in 565799d8f6ebf1a8 network):<br />
<nowiki>192.168.192.171/24</nowiki><br />
<br />
In /home/pi/.ssh/authorized_keys public keys of maxigas and marcell are added.<br />

= Ideas for building Voja's scanner =<br />
<br />
Our first idea was to reproduce Voja's scanner but we had to realise that we are not Voja and the scanner is very beautiful and unique engineering and consequently it is hard to reproduce. <br />
<br />
Here are two links to the public documentation of our scanner, built by Voja Antonic:<br />
<br />
https://www.memoryoftheworld.org/blog/2012/10/28/our-beloved-bookscanner-2/<br />
<br />
https://hackaday.io/project/5604-diy-book-scanner<br />
<br />
The electronics is not really documented (which means that it is hard to reproduce) and it is built from basic parts (which means that it takes a lot of time to put it together). So we brainstorm about an Arduino-based solution instead. Arduino is a general-purpose programmable microcontroller that has already built-in many of the functions/parts we need. The idea is that this makes it easier for us to build the scanner and for others to reproduce it. We also have more experience working with Arduino than with only basic electronic components. <br />
<br />
We will also try to use cheaper cameras in order to bring down the budget.<br />

<div>Bookscanning in Calafou:<br />
<br />
* We made an event called Hack the Biblio: Let's make Digital Public Libraries in 2014 as a collaboration with memoryoftheworld, when Voja Antonic donated a bookscanner to Calafou: https://calafou.org/en/content/hack-biblio-construir-bibliotecas-publicas https://calafou.org/en/content/voja-antonic-calafou<br />
* We scan out of print books published by Virus: http://www.viruseditorial.net/<br />
* We built a book scanner in 2018 during the Kunlabora event for supporting other collectives that want to scan: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative<br />
<br />
This page is documenting the design and construction of bookscanners. For the tutorial that explains "How to use the bookscanner", go to http://wiki.calafou.org/index.php/Bookscanning<br />
<br />
= Building a "New Standard Scanner" =<br />
<br />
We built this: https://forum.diybookscanner.org/viewtopic.php?f=1&t=333 during the Kunlabora event in Calafou: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative A more reproducible and portable and simple scanner.<br />
<br />
In theory for the simple scanner it should be possible to get all the ingredients from a hardware shop ("ferreteria"). We got most of the materials from Bauhaus in Barcelona (Zona Franca). Our experience was that most of the screws, nuts and bolts are easy to substitute with others that have more or less the same dimensions.<br />
<br />
[[File:bookscanner_pseudoready2.jpg|600px]] <br />
<br />
== Budget ==<br />
<br />
Kunlabora event was four days of collaborative construction. More or less six persons worked on building the scanner. This is the receipts that we spent, because we had 500 EUR budget for the raw materials from the participation fee of the event. <br />
<br />
Receipts:<br />
<br />
25 2x plexiglass [J] @ Expocryl, Igualada<br />
18 2x SD cards @ Life Informatica, Barcelona<br />
50 2x magic want camera stand @ FotoK, Barcelona<br />

108.8 Nuts/bolts/etc. @ Bauhaus, Zona Franca, Barcelona<br />
10 2x USB cable male/female @ Worten San Antoni, Barcelona<br />
5 2x mini USB (USB-B) cable @ Tienda Cables, Barcelona<br />
178 2x Canon IXUS 175 compact digital camera @ Amazon.es<br />
60 4x Wooden beams (listones) @ Fustes Fargas, Barcelona<br />
============================================<br />
497<br />
<br />
Donations:<br />
<br />
70 Raspberry Pi 3 (Model B), 2x SD cards, 5V charger, rulers [M] @ Barcelona<br />
<br />
We also used nuts and bolts, etc. found in the workshop of Calafou (in Catalunya, near Barcelona). The conclusion is that it should be possible to build this scanner from about 5-600 EUR anywhere in (Western) Europe. We did not use all the materials we bought and if we would do it again then we tried to use real wood instead of FDM, because the latter proved very fragile. However, this could make the platen more heavy, and it is already quite heavy.<br />

<b>Things to take in consideration from the building experience</b><br />
<br />
* the MDF pieces are fragile and gave us problems when introducing screws<br />
* we considered varnishing the wood pieces to limit humidity impact<br />
* the plexiglas we bought generates many reflections<br />
* passing from inches to cm was uncomfortable<br />
* the position and height of the light should be tested before being fixed<br />
* the upper part of the light stand should be easier to mount and unmount for transportation<br />
* the wood used for the platen should be without texture or painted with mate dark paint<br />
* the gooseneck (Manfrotto) option for the camera stand is not a good option: it is very easy to put the camera in the way of the cradle; the calibration process is difficult because the cameras can move in the three axis; they are springy and difficult to set in an exact position<br />
<br />
== Cameras ==<br />
<br />
The bookscanner is basically a glorified camera stand that allows us to take good pictures of book pages. So the cameras are an important part of the bookscanner. Summary of research about cameras for book scanners:<br />
<br />
Basically there are three categories of cameras that can be used for book scanners (from cheapest to most expensive).<br />
<br />
1. Remote control support<br />
<br />
The cheapest option is any camera with remote trigger support, so we can take pictures without pushing the button on the camera. This is important because when you press the button the camera position may be disadjusted to the physical pressure.<br />
<br />
2. CHDK firmware<br />
<br />
Middle category is CHDK firmware compatibles. CHDK is a third party open source firmware that allows the customisation of cameras. CHDK firmware is for Canon Powershot cameras, which are the cheaper compact digital camera product line. We have 200 euros in the budget for cameras, so we went with this option.<br />
<br />
3. Magic Lantern support<br />
<br />
Magic Lantern is a third party open source firmware that is more advanced. However, it only works with Canon DLSR cameras (these are the cameras that have a reflex mirror to look at the shot through a small hole before you take the picture, and they usually have big lenses). The scanner we have now uses Canon 1100D, which are the cheapest type suported by Magic Lantern, but they still cost a few hundred euros.<br />
<br />
4. Connecting to a monitor<br />
<br />
It is very useful to be able to connect the cameras to a monitor during the calibration process. The cameras we bought use the same output for connecting to a remote control and to a monitor making it not practical at all using a monitor. Furthermore, connection with usb to a computer monitor was not an option, we had to look for RC connectors or adapters.<br />

[[File:02 BASE 043.JPG|500px|none|left]]<br />
[[File:02 BASE 040.JPG|500px|none|left]]<br />
We cut the wood beams to have 2 pieces of 56x4cm and 2 of 31.5x4cm<br />
<br />
[[File:02 BASE 044.JPG|500px|none|left]]<br />
[[File:02 BASE 041.JPG|500px|none|left]]<br />
we measured with precision tools and marked the position of the drawer sliders on the 54x4cm wood beams <br />
<br />
[[File:02 BASE 045.JPG|500px|none|left]]<br />
we drilled holes on the marked position<br />

and then we fixed the sliders<br />

We used the thicker MDF material to cut a 37x29cm sheet<br />
<br />
[[File:02 BASE 056.JPG|500px|none|left]]<br />
The last parts were fixing the other part of the sliders to the MDF sheet and attaching the different part of the base with screws<br />

= Raspberry Pi for the bookscanner =<br />
<br />
At the moment we use an electromechanical button documented on the CHDK website that works well but does not do much more than triggering the two cameras to shoot at the same time: http://chdk.wikia.com/wiki/USB_Remote<br />
<br />
There are many more possibilities of how to optimise the bookscanning process. Many ideas start with connecting the cameras to a small computer such as the Raspberry Pi. We made some experiments and tests with this setup, which is documented below:<br />
<br />
It runs [https://www.raspbian.org/ Raspbian].<br />
<br />
== CHDKPTP ==<br />
<br />
In /home/pi/chdkptp there are precompiled binaries of [https://app.assembla.com/spaces/chdkptp/wiki CHDKPTP] downloaded from [https://app.assembla.com/spaces/chdkptp/documents here].<br />
<br />
CHDKPTP is used for remote control of camera running CHDK firmware.<br />
<br />
Our setup has two modes of work:<br />
* mechanical "button" which triggers both camera capturing its photo based on this tutorial: http://chdk.wikia.com/wiki/USB_Remote<br />
* (in progress) Raspberry Pi mode where an bookscanner operator uses Raspberry Pi to capture photos, preview photos in real time and transfer them already renamed for the next step in Scantailor.<br />
<br />
When camera is connected this line will list info about the camera e.g.:<br />
<nowiki>sudo ./chdkptp.sh -elist</nowiki><br />
and for one of the camera this is what is listed then:<br />
<nowiki>-1:Canon IXUS 175 b=001 d=030 v=0x4a9 p=0x32c1 s=8B20D62641B041BAA3E1D597D560D110</nowiki><br />
<br />
An example of capturing a picture from commandline (once in /home/pi/chdkptp/):<br />
<nowiki>sudo ./chdkptp.sh -e"connect -d=030" -erec -eshoot</nowiki><br />
Above line connects to the camera sitting on -d=021, puts it into rec mode (if not already) and capture the photo saving it to SD card already in camera. If one wants to bypass the SD card altogether it should replace -eshoot with -eremoteshoot. In that case ./chdkptp.sh will save photos into the directory from where it was called.<br />
<br />
Note: check the SD card is locked.<br />

<div>Bookscanning in Calafou:<br />
<br />
* We made an event called Hack the Biblio: Let's make Digital Public Libraries in 2014 as a collaboration with memoryoftheworld, when Voja Antonic donated a bookscanner to Calafou: https://calafou.org/en/content/hack-biblio-construir-bibliotecas-publicas https://calafou.org/en/content/voja-antonic-calafou<br />
* We scan out of print books published by Virus: http://www.viruseditorial.net/<br />
* We built a book scanner in 2018 during the Kunlabora event for supporting other collectives that want to scan: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative<br />
<br />
This page is documenting the design and construction of bookscanners. For the tutorial that explains "How to use the bookscanner", go to http://wiki.calafou.org/index.php/Bookscanning<br />
<br />
= Building a "New Standard Scanner" =<br />
<br />
We built this: https://forum.diybookscanner.org/viewtopic.php?f=1&t=333 during the Kunlabora event in Calafou: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative A more reproducible and portable and simple scanner.<br />
<br />
In theory for the simple scanner it should be possible to get all the ingredients from a hardware shop ("ferreteria"). We got most of the materials from Bauhaus in Barcelona (Zona Franca). Our experience was that most of the screws, nuts and bolts are easy to substitute with others that have more or less the same dimensions.<br />
<br />

<br />
== Budget ==<br />
<br />
Kunlabora event was four days of collaborative construction. More or less six persons worked on building the scanner. This is the receipts that we spent, because we had 500 EUR budget for the raw materials from the participation fee of the event. <br />
<br />
Receipts:<br />
<br />
25 2x plexiglass [J] @ Expocryl, Igualada<br />
18 2x SD cards @ Life Informatica, Barcelona<br />
50 2x magic want camera stand @ FotoK, Barcelona<br />

<br />
Donations:<br />
<br />
70 Raspberry Pi 3 (Model B), 2x SD cards, 5V charger, rulers [M] @ Barcelona<br />
<br />
We also used nuts and bolts, etc. found in the workshop of Calafou (in Catalunya, near Barcelona). The conclusion is that it should be possible to build this scanner from about 5-600 EUR anywhere in (Western) Europe. We did not use all the materials we bought and if we would do it again then we tried to use real wood instead of FDM, because the latter proved very fragile. However, this could make the platen more heavy, and it is already quite heavy.<br />

<b>Things to take in consideration from the building experience</b><br />
<br />
* the MDF pieces are fragile and gave us problems when introducing screws<br />
* we considered varnishing the wood pieces to limit humidity impact<br />
* the plexiglas we bought generates many reflections<br />
* passing from inches to cm was uncomfortable<br />
* the position and height of the light should be tested before being fixed<br />
* the upper part of the light stand should be easier to mount and unmount for transportation<br />
* the wood used for the platen should be without texture or painted with mate dark paint<br />
* the gooseneck (Manfrotto) option for the camera stand is not a good option: it is very easy to put the camera in the way of the cradle; the calibration process is difficult because the cameras can move in the three axis; they are springy and difficult to set in an exact position<br />
<br />
== Cameras ==<br />
<br />
The bookscanner is basically a glorified camera stand that allows us to take good pictures of book pages. So the cameras are an important part of the bookscanner. Summary of research about cameras for book scanners:<br />
<br />
Basically there are three categories of cameras that can be used for book scanners (from cheapest to most expensive).<br />
<br />
1. Remote control support<br />
<br />
The cheapest option is any camera with remote trigger support, so we can take pictures without pushing the button on the camera. This is important because when you press the button the camera position may be disadjusted to the physical pressure.<br />
<br />
2. CHDK firmware<br />
<br />
Middle category is CHDK firmware compatibles. CHDK is a third party open source firmware that allows the customisation of cameras. CHDK firmware is for Canon Powershot cameras, which are the cheaper compact digital camera product line. We have 200 euros in the budget for cameras, so we went with this option.<br />
<br />
3. Magic Lantern support<br />
<br />
Magic Lantern is a third party open source firmware that is more advanced. However, it only works with Canon DLSR cameras (these are the cameras that have a reflex mirror to look at the shot through a small hole before you take the picture, and they usually have big lenses). The scanner we have now uses Canon 1100D, which are the cheapest type suported by Magic Lantern, but they still cost a few hundred euros.<br />
<br />
4. Connecting to a monitor<br />
<br />
It is very useful to be able to connect the cameras to a monitor during the calibration process. The cameras we bought use the same output for connecting to a remote control and to a monitor making it not practical at all using a monitor. Furthermore, connection with usb to a computer monitor was not an option, we had to look for RC connectors or adapters.<br />

[[File:02 BASE 043.JPG|500px|none|left]]<br />
[[File:02 BASE 040.JPG|500px|none|left]]<br />
We cut the wood beams to have 2 pieces of 56x4cm and 2 of 31.5x4cm<br />
<br />
[[File:02 BASE 041.JPG|500px|none|left]]<br />
[[File:02 BASE 044.JPG|500px|none|left]]<br />
we measured with precision tools and marked the position of the drawer sliders on the 54x4cm wood beams <br />
<br />
[[File:02 BASE 045.JPG|500px|none|left]]<br />
we drilled holes on the marked position<br />

and then we fixed the sliders<br />
<br />
[[File:02 BASE 033.JPG|500px|none|left]]<br />
We used the thicker MDF material to cut a 37x29cm sheet<br />
<br />
[[File:02 BASE 056.JPG|500px|none|left]]<br />
The last parts were fixing the other part of the sliders to the MDF sheet and attaching the different part of the base with screws<br />

= Raspberry Pi for the bookscanner =<br />
<br />
At the moment we use an electromechanical button documented on the CHDK website that works well but does not do much more than triggering the two cameras to shoot at the same time: http://chdk.wikia.com/wiki/USB_Remote<br />
<br />
There are many more possibilities of how to optimise the bookscanning process. Many ideas start with connecting the cameras to a small computer such as the Raspberry Pi. We made some experiments and tests with this setup, which is documented below:<br />
<br />
It runs [https://www.raspbian.org/ Raspbian].<br />
<br />
== CHDKPTP ==<br />
<br />
In /home/pi/chdkptp there are precompiled binaries of [https://app.assembla.com/spaces/chdkptp/wiki CHDKPTP] downloaded from [https://app.assembla.com/spaces/chdkptp/documents here].<br />
<br />
CHDKPTP is used for remote control of camera running CHDK firmware.<br />
<br />
Our setup has two modes of work:<br />
* mechanical "button" which triggers both camera capturing its photo based on this tutorial: http://chdk.wikia.com/wiki/USB_Remote<br />
* (in progress) Raspberry Pi mode where an bookscanner operator uses Raspberry Pi to capture photos, preview photos in real time and transfer them already renamed for the next step in Scantailor.<br />
<br />
When camera is connected this line will list info about the camera e.g.:<br />
<nowiki>sudo ./chdkptp.sh -elist</nowiki><br />
and for one of the camera this is what is listed then:<br />
<nowiki>-1:Canon IXUS 175 b=001 d=030 v=0x4a9 p=0x32c1 s=8B20D62641B041BAA3E1D597D560D110</nowiki><br />
<br />
An example of capturing a picture from commandline (once in /home/pi/chdkptp/):<br />
<nowiki>sudo ./chdkptp.sh -e"connect -d=030" -erec -eshoot</nowiki><br />
Above line connects to the camera sitting on -d=021, puts it into rec mode (if not already) and capture the photo saving it to SD card already in camera. If one wants to bypass the SD card altogether it should replace -eshoot with -eremoteshoot. In that case ./chdkptp.sh will save photos into the directory from where it was called.<br />
<br />
Note: check the SD card is locked.<br />
<br />
== ZeroTier ==<br />
<br />
It is added to 565799d8f6ebf1a8 public network of [https://zerotier.com ZeroTier] with this command:<br />
<nowiki>sudo zerotier-cli join 565799d8f6ebf1a8</nowiki><br />
and it got static IP address (in 565799d8f6ebf1a8 network):<br />
<nowiki>192.168.192.171/24</nowiki><br />
<br />
In /home/pi/.ssh/authorized_keys public keys of maxigas and marcell are added.<br />
<br />
= Ideas for building Voja's scanner =<br />
<br />
Our first idea was to reproduce Voja's scanner but we had to realise that we are not Voja and the scanner is very beautiful and unique engineering and consequently it is hard to reproduce. <br />
<br />
Here are two links to the public documentation of our scanner, built by Voja Antonic:<br />
<br />
https://www.memoryoftheworld.org/blog/2012/10/28/our-beloved-bookscanner-2/<br />
<br />
https://hackaday.io/project/5604-diy-book-scanner<br />
<br />
The electronics is not really documented (which means that it is hard to reproduce) and it is built from basic parts (which means that it takes a lot of time to put it together). So we brainstorm about an Arduino-based solution instead. Arduino is a general-purpose programmable microcontroller that has already built-in many of the functions/parts we need. The idea is that this makes it easier for us to build the scanner and for others to reproduce it. We also have more experience working with Arduino than with only basic electronic components. <br />
<br />
We will also try to use cheaper cameras in order to bring down the budget.<br />

= Building a "New Standard Scanner" =<br />
<br />
We built this: https://forum.diybookscanner.org/viewtopic.php?f=1&t=333 during the Kunlabora event in Calafou: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative A more reproducible and portable and simple scanner.<br />
<br />
In theory for the simple scanner it should be possible to get all the ingredients from a hardware shop ("ferreteria"). We got most of the materials from Bauhaus in Barcelona (Zona Franca). Our experience was that most of the screws, nuts and bolts are easy to substitute with others that have more or less the same dimensions.<br />

<b>Things to take in consideration from the building experience</b><br />
<br />
* the MDF pieces are fragile and gave us problems when introducing screws<br />
* we considered varnishing the wood pieces to limit humidity impact<br />
* the plexiglas we bought generates many reflections<br />
* passing from inches to cm was uncomfortable<br />
* the position and height of the light should be tested before being fixed<br />
* the upper part of the light stand should be easier to mount and unmount for transportation<br />
* the wood used for the platen should be without texture or painted with mate dark paint<br />
* the gooseneck (Manfrotto) option for the camera stand is not a good option: it is very easy to put the camera in the way of the cradle; the calibration process is difficult because the cameras can move in the three axis; they are springy and difficult to set in an exact position<br />
<br />
== Cameras ==<br />
<br />
The bookscanner is basically a glorified camera stand that allows us to take good pictures of book pages. So the cameras are an important part of the bookscanner. Summary of research about cameras for book scanners:<br />
<br />
Basically there are three categories of cameras that can be used for book scanners (from cheapest to most expensive).<br />
<br />
1. Remote control support<br />
<br />
The cheapest option is any camera with remote trigger support, so we can take pictures without pushing the button on the camera. This is important because when you press the button the camera position may be disadjusted to the physical pressure.<br />
<br />
2. CHDK firmware<br />
<br />
Middle category is CHDK firmware compatibles. CHDK is a third party open source firmware that allows the customisation of cameras. CHDK firmware is for Canon Powershot cameras, which are the cheaper compact digital camera product line. We have 200 euros in the budget for cameras, so we went with this option.<br />
<br />
3. Magic Lantern support<br />
<br />
Magic Lantern is a third party open source firmware that is more advanced. However, it only works with Canon DLSR cameras (these are the cameras that have a reflex mirror to look at the shot through a small hole before you take the picture, and they usually have big lenses). The scanner we have now uses Canon 1100D, which are the cheapest type suported by Magic Lantern, but they still cost a few hundred euros.<br />
<br />
4. Connecting to a monitor<br />
<br />
It is very useful to be able to connect the cameras to a monitor during the calibration process. The cameras we bought use the same output for connecting to a remote control and to a monitor making it not practical at all using a monitor. Furthermore, connection with usb to a computer monitor was not an option, we had to look for RC connectors or adapters.<br />

= Raspberry Pi for the bookscanner =<br />
<br />
At the moment we use an electromechanical button documented on the CHDK website that works well but does not do much more than triggering the two cameras to shoot at the same time: http://chdk.wikia.com/wiki/USB_Remote<br />
<br />
There are many more possibilities of how to optimise the bookscanning process. Many ideas start with connecting the cameras to a small computer such as the Raspberry Pi. We made some experiments and tests with this setup, which is documented below:<br />
<br />
It runs [https://www.raspbian.org/ Raspbian].<br />
<br />
== CHDKPTP ==<br />
<br />
In /home/pi/chdkptp there are precompiled binaries of [https://app.assembla.com/spaces/chdkptp/wiki CHDKPTP] downloaded from [https://app.assembla.com/spaces/chdkptp/documents here].<br />
<br />
CHDKPTP is used for remote control of camera running CHDK firmware.<br />
<br />
Our setup has two modes of work:<br />
* mechanical "button" which triggers both camera capturing its photo based on this tutorial: http://chdk.wikia.com/wiki/USB_Remote<br />
* (in progress) Raspberry Pi mode where an bookscanner operator uses Raspberry Pi to capture photos, preview photos in real time and transfer them already renamed for the next step in Scantailor.<br />
<br />
When camera is connected this line will list info about the camera e.g.:<br />
<nowiki>sudo ./chdkptp.sh -elist</nowiki><br />
and for one of the camera this is what is listed then:<br />
<nowiki>-1:Canon IXUS 175 b=001 d=030 v=0x4a9 p=0x32c1 s=8B20D62641B041BAA3E1D597D560D110</nowiki><br />
<br />
An example of capturing a picture from commandline (once in /home/pi/chdkptp/):<br />
<nowiki>sudo ./chdkptp.sh -e"connect -d=030" -erec -eshoot</nowiki><br />
Above line connects to the camera sitting on -d=021, puts it into rec mode (if not already) and capture the photo saving it to SD card already in camera. If one wants to bypass the SD card altogether it should replace -eshoot with -eremoteshoot. In that case ./chdkptp.sh will save photos into the directory from where it was called.<br />
<br />
Note: check the SD card is locked.<br />
<br />
== ZeroTier ==<br />
<br />
It is added to 565799d8f6ebf1a8 public network of [https://zerotier.com ZeroTier] with this command:<br />
<nowiki>sudo zerotier-cli join 565799d8f6ebf1a8</nowiki><br />
and it got static IP address (in 565799d8f6ebf1a8 network):<br />
<nowiki>192.168.192.171/24</nowiki><br />
<br />
In /home/pi/.ssh/authorized_keys public keys of maxigas and marcell are added.<br />
<br />
= Ideas for building Voja's scanner =<br />
<br />
Our first idea was to reproduce Voja's scanner but we had to realise that we are not Voja and the scanner is very beautiful and unique engineering and consequently it is hard to reproduce. <br />
<br />
Here are two links to the public documentation of our scanner, built by Voja Antonic:<br />
<br />
https://www.memoryoftheworld.org/blog/2012/10/28/our-beloved-bookscanner-2/<br />
<br />
https://hackaday.io/project/5604-diy-book-scanner<br />
<br />
The electronics is not really documented (which means that it is hard to reproduce) and it is built from basic parts (which means that it takes a lot of time to put it together). So we brainstorm about an Arduino-based solution instead. Arduino is a general-purpose programmable microcontroller that has already built-in many of the functions/parts we need. The idea is that this makes it easier for us to build the scanner and for others to reproduce it. We also have more experience working with Arduino than with only basic electronic components. <br />
<br />
We will also try to use cheaper cameras in order to bring down the budget.<br />

<div>Bookscanning in Calafou:<br />
<br />
* We made an event called Hack the Biblio: Let's make Digital Public Libraries in 2014 as a collaboration with memoryoftheworld, when Voja Antonic donated a bookscanner to Calafou: https://calafou.org/en/content/hack-biblio-construir-bibliotecas-publicas https://calafou.org/en/content/voja-antonic-calafou<br />
* We scan out of print books published by Virus: http://www.viruseditorial.net/<br />
* We built a book scanner in 2018 during the Kunlabora event for supporting other collectives that want to scan: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative<br />
<br />
This page is documenting the design and construction of bookscanners. For the tutorial that explains "How to use the bookscanner", go to http://wiki.calafou.org/index.php/Bookscanning<br />
<br />
= Building a "New Standard Scanner" =<br />
<br />
We built this: https://forum.diybookscanner.org/viewtopic.php?f=1&t=333 during the Kunlabora event in Calafou: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative A more reproducible and portable and simple scanner.<br />
<br />
In theory for the simple scanner it should be possible to get all the ingredients from a hardware shop ("ferreteria"). We got most of the materials from Bauhaus in Barcelona (Zona Franca). Our experience was that most of the screws, nuts and bolts are easy to substitute with others that have more or less the same dimensions.<br />
<br />
[[File:bookscanner_pseudoready2.jpg|600px]] <br />
<br />
== Budget ==<br />
<br />
Kunlabora event was four days of collaborative construction. More or less six persons worked on building the scanner. This is the receipts that we spent, because we had 500 EUR budget for the raw materials from the participation fee of the event. <br />
<br />
Receipts:<br />
<br />
25 2x plexiglass [J] @ Expocryl, Igualada<br />
18 2x SD cards @ Life Informatica, Barcelona<br />
50 2x magic want camera stand @ FotoK, Barcelona<br />
42.2 Nuts/bolts/etc. @ Bauhaus, Zona Franca, Barcelona<br />
108.8 Nuts/bolts/etc. @ Bauhaus, Zona Franca, Barcelona<br />
10 2x USB cable male/female @ Worten San Antoni, Barcelona<br />
5 2x mini USB (USB-B) cable @ Tienda Cables, Barcelona<br />
178 2x Canon IXUS 175 compact digital camera @ Amazon.es<br />
60 4x Wooden beams (listones) @ Fustes Fargas, Barcelona<br />
============================================<br />
497<br />
<br />
Donations:<br />
<br />
70 Raspberry Pi 3 (Model B), 2x SD cards, 5V charger, rulers [M] @ Barcelona<br />
<br />
We also used nuts and bolts, etc. found in the workshop of Calafou (in Catalunya, near Barcelona). The conclusion is that it should be possible to build this scanner from about 5-600 EUR anywhere in (Western) Europe. We did not use all the materials we bought and if we would do it again then we tried to use real wood instead of FDM, because the latter proved very fragile. However, this could make the platen more heavy, and it is already quite heavy.<br />

== Cameras ==<br />
<br />
The bookscanner is basically a glorified camera stand that allows us to take good pictures of book pages. So the cameras are an important part of the bookscanner. Summary of research about cameras for book scanners:<br />
<br />
Basically there are three categories of cameras that can be used for book scanners (from cheapest to most expensive).<br />
<br />
1. Remote control support<br />
<br />
The cheapest option is any camera with remote trigger support, so we can take pictures without pushing the button on the camera. This is important because when you press the button the camera position may be disadjusted to the physical pressure.<br />
<br />
2. CHDK firmware<br />
<br />
Middle category is CHDK firmware compatibles. CHDK is a third party open source firmware that allows the customisation of cameras. CHDK firmware is for Canon Powershot cameras, which are the cheaper compact digital camera product line. We have 200 euros in the budget for cameras, so we went with this option.<br />
<br />
3. Magic Lantern support<br />
<br />
Magic Lantern is a third party open source firmware that is more advanced. However, it only works with Canon DLSR cameras (these are the cameras that have a reflex mirror to look at the shot through a small hole before you take the picture, and they usually have big lenses). The scanner we have now uses Canon 1100D, which are the cheapest type suported by Magic Lantern, but they still cost a few hundred euros.<br />
<br />
4. Connecting to a monitor<br />
<br />
It is very useful to be able to connect the cameras to a monitor during the calibration process. The cameras we bought use the same output for connecting to a remote control and to a monitor making it not practical at all using a monitor. Furthermore, connection with usb to a computer monitor was not an option, we had to look for RC connectors or adapters.<br />

= Raspberry Pi for the bookscanner =<br />
<br />
At the moment we use an electromechanical button documented on the CHDK website that works well but does not do much more than triggering the two cameras to shoot at the same time: http://chdk.wikia.com/wiki/USB_Remote<br />
<br />
There are many more possibilities of how to optimise the bookscanning process. Many ideas start with connecting the cameras to a small computer such as the Raspberry Pi. We made some experiments and tests with this setup, which is documented below:<br />
<br />
It runs [https://www.raspbian.org/ Raspbian].<br />
<br />
== CHDKPTP ==<br />
<br />
In /home/pi/chdkptp there are precompiled binaries of [https://app.assembla.com/spaces/chdkptp/wiki CHDKPTP] downloaded from [https://app.assembla.com/spaces/chdkptp/documents here].<br />
<br />
CHDKPTP is used for remote control of camera running CHDK firmware.<br />
<br />
Our setup has two modes of work:<br />
* mechanical "button" which triggers both camera capturing its photo based on this tutorial: http://chdk.wikia.com/wiki/USB_Remote<br />
* (in progress) Raspberry Pi mode where an bookscanner operator uses Raspberry Pi to capture photos, preview photos in real time and transfer them already renamed for the next step in Scantailor.<br />
<br />
When camera is connected this line will list info about the camera e.g.:<br />
<nowiki>sudo ./chdkptp.sh -elist</nowiki><br />
and for one of the camera this is what is listed then:<br />
<nowiki>-1:Canon IXUS 175 b=001 d=030 v=0x4a9 p=0x32c1 s=8B20D62641B041BAA3E1D597D560D110</nowiki><br />
<br />
An example of capturing a picture from commandline (once in /home/pi/chdkptp/):<br />
<nowiki>sudo ./chdkptp.sh -e"connect -d=030" -erec -eshoot</nowiki><br />
Above line connects to the camera sitting on -d=021, puts it into rec mode (if not already) and capture the photo saving it to SD card already in camera. If one wants to bypass the SD card altogether it should replace -eshoot with -eremoteshoot. In that case ./chdkptp.sh will save photos into the directory from where it was called.<br />
<br />
Note: check the SD card is locked.<br />
<br />
== ZeroTier ==<br />
<br />
It is added to 565799d8f6ebf1a8 public network of [https://zerotier.com ZeroTier] with this command:<br />
<nowiki>sudo zerotier-cli join 565799d8f6ebf1a8</nowiki><br />
and it got static IP address (in 565799d8f6ebf1a8 network):<br />
<nowiki>192.168.192.171/24</nowiki><br />
<br />
In /home/pi/.ssh/authorized_keys public keys of maxigas and marcell are added.<br />
<br />
= Ideas for building Voja's scanner =<br />
<br />
Our first idea was to reproduce Voja's scanner but we had to realise that we are not Voja and the scanner is very beautiful and unique engineering and consequently it is hard to reproduce. <br />
<br />
Here are two links to the public documentation of our scanner, built by Voja Antonic:<br />
<br />
https://www.memoryoftheworld.org/blog/2012/10/28/our-beloved-bookscanner-2/<br />
<br />
https://hackaday.io/project/5604-diy-book-scanner<br />
<br />
The electronics is not really documented (which means that it is hard to reproduce) and it is built from basic parts (which means that it takes a lot of time to put it together). So we brainstorm about an Arduino-based solution instead. Arduino is a general-purpose programmable microcontroller that has already built-in many of the functions/parts we need. The idea is that this makes it easier for us to build the scanner and for others to reproduce it. We also have more experience working with Arduino than with only basic electronic components. <br />
<br />
We will also try to use cheaper cameras in order to bring down the budget.<br />

<div>Bookscanning in Calafou:<br />
<br />
* We made an event called Hack the Biblio: Let's make Digital Public Libraries in 2014 as a collaboration with memoryoftheworld, when Voja Antonic donated a bookscanner to Calafou: https://calafou.org/en/content/hack-biblio-construir-bibliotecas-publicas https://calafou.org/en/content/voja-antonic-calafou<br />
* We scan out of print books published by Virus: http://www.viruseditorial.net/<br />
* We built a book scanner in 2018 during the Kunlabora event for supporting other collectives that want to scan: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative<br />
<br />
This page is documenting the design and construction of bookscanners. For the tutorial that explains "How to use the bookscanner", go to http://wiki.calafou.org/index.php/Bookscanning<br />
<br />
= Building a "New Standard Scanner" =<br />
<br />
We built this: https://forum.diybookscanner.org/viewtopic.php?f=1&t=333 during the Kunlabora event in Calafou: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative A more reproducible and portable and simple scanner.<br />
<br />
In theory for the simple scanner it should be possible to get all the ingredients from a hardware shop ("ferreteria"). We got most of the materials from Bauhaus in Barcelona (Zona Franca). Our experience was that most of the screws, nuts and bolts are easy to substitute with others that have more or less the same dimensions.<br />
<br />
[[File:bookscanner_pseudoready2.jpg|600px]] <br />
<br />
== Budget ==<br />
<br />
Kunlabora event was four days of collaborative construction. More or less six persons worked on building the scanner. This is the receipts that we spent, because we had 500 EUR budget for the raw materials from the participation fee of the event. <br />
<br />
Receipts:<br />
<br />
25 2x plexiglass [J] @ Expocryl, Igualada<br />
18 2x SD cards @ Life Informatica, Barcelona<br />
50 2x magic want camera stand @ FotoK, Barcelona<br />
42.2 Nuts/bolts/etc. @ Bauhaus, Zona Franca, Barcelona<br />
108.8 Nuts/bolts/etc. @ Bauhaus, Zona Franca, Barcelona<br />
10 2x USB cable male/female @ Worten San Antoni, Barcelona<br />
5 2x mini USB (USB-B) cable @ Tienda Cables, Barcelona<br />
178 2x Canon IXUS 175 compact digital camera @ Amazon.es<br />
60 4x Wooden beams (listones) @ Fustes Fargas, Barcelona<br />
============================================<br />
497<br />
<br />
Donations:<br />
<br />
70 Raspberry Pi 3 (Model B), 2x SD cards, 5V charger, rulers [M] @ Barcelona<br />
<br />
We also used nuts and bolts, etc. found in the workshop of Calafou (in Catalunya, near Barcelona). The conclusion is that it should be possible to build this scanner from about 5-600 EUR anywhere in (Western) Europe. We did not use all the materials we bought and if we would do it again then we tried to use real wood instead of FDM, because the latter proved very fragile. However, this could make the platen more heavy, and it is already quite heavy.<br />

= Raspberry Pi for the bookscanner =<br />
<br />
At the moment we use an electromechanical button documented on the CHDK website that works well but does not do much more than triggering the two cameras to shoot at the same time: http://chdk.wikia.com/wiki/USB_Remote<br />
<br />
There are many more possibilities of how to optimise the bookscanning process. Many ideas start with connecting the cameras to a small computer such as the Raspberry Pi. We made some experiments and tests with this setup, which is documented below:<br />
<br />
It runs [https://www.raspbian.org/ Raspbian].<br />
<br />
== CHDKPTP ==<br />
<br />
In /home/pi/chdkptp there are precompiled binaries of [https://app.assembla.com/spaces/chdkptp/wiki CHDKPTP] downloaded from [https://app.assembla.com/spaces/chdkptp/documents here].<br />
<br />
CHDKPTP is used for remote control of camera running CHDK firmware.<br />
<br />
Our setup has two modes of work:<br />
* mechanical "button" which triggers both camera capturing its photo based on this tutorial: http://chdk.wikia.com/wiki/USB_Remote<br />
* (in progress) Raspberry Pi mode where an bookscanner operator uses Raspberry Pi to capture photos, preview photos in real time and transfer them already renamed for the next step in Scantailor.<br />
<br />
When camera is connected this line will list info about the camera e.g.:<br />
<nowiki>sudo ./chdkptp.sh -elist</nowiki><br />
and for one of the camera this is what is listed then:<br />
<nowiki>-1:Canon IXUS 175 b=001 d=030 v=0x4a9 p=0x32c1 s=8B20D62641B041BAA3E1D597D560D110</nowiki><br />
<br />
An example of capturing a picture from commandline (once in /home/pi/chdkptp/):<br />
<nowiki>sudo ./chdkptp.sh -e"connect -d=030" -erec -eshoot</nowiki><br />
Above line connects to the camera sitting on -d=021, puts it into rec mode (if not already) and capture the photo saving it to SD card already in camera. If one wants to bypass the SD card altogether it should replace -eshoot with -eremoteshoot. In that case ./chdkptp.sh will save photos into the directory from where it was called.<br />
<br />
Note: check the SD card is locked.<br />
<br />
== ZeroTier ==<br />
<br />
It is added to 565799d8f6ebf1a8 public network of [https://zerotier.com ZeroTier] with this command:<br />
<nowiki>sudo zerotier-cli join 565799d8f6ebf1a8</nowiki><br />
and it got static IP address (in 565799d8f6ebf1a8 network):<br />
<nowiki>192.168.192.171/24</nowiki><br />
<br />
In /home/pi/.ssh/authorized_keys public keys of maxigas and marcell are added.<br />

= Ideas for building Voja's scanner =<br />
<br />
Our first idea was to reproduce Voja's scanner but we had to realise that we are not Voja and the scanner is very beautiful and unique engineering and consequently it is hard to reproduce. <br />
<br />
Here are two links to the public documentation of our scanner, built by Voja Antonic:<br />
<br />
https://www.memoryoftheworld.org/blog/2012/10/28/our-beloved-bookscanner-2/<br />
<br />
https://hackaday.io/project/5604-diy-book-scanner<br />
<br />
The electronics is not really documented (which means that it is hard to reproduce) and it is built from basic parts (which means that it takes a lot of time to put it together). So we brainstorm about an Arduino-based solution instead. Arduino is a general-purpose programmable microcontroller that has already built-in many of the functions/parts we need. The idea is that this makes it easier for us to build the scanner and for others to reproduce it. We also have more experience working with Arduino than with only basic electronic components. <br />
<br />
We will also try to use cheaper cameras in order to bring down the budget.<br />

<div>Bookscanning in Calafou:<br />
<br />
* We made an event called Hack the Biblio: Let's make Digital Public Libraries in 2014 as a collaboration with memoryoftheworld, when Voja Antonic donated a bookscanner to Calafou: https://calafou.org/en/content/hack-biblio-construir-bibliotecas-publicas https://calafou.org/en/content/voja-antonic-calafou<br />
* We scan out of print books published by Virus: http://www.viruseditorial.net/<br />
* We built a book scanner in 2018 during the Kunlabora event for supporting other collectives that want to scan: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative<br />
<br />
This page is documenting the design and construction of bookscanners. For the tutorial that explains "How to use the bookscanner", go to http://wiki.calafou.org/index.php/Bookscanning<br />
<br />
= Building a "New Standard Scanner" =<br />
<br />
We built this: https://forum.diybookscanner.org/viewtopic.php?f=1&t=333 during the Kunlabora event in Calafou: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative A more reproducible and portable and simple scanner.<br />
<br />
In theory for the simple scanner it should be possible to get all the ingredients from a hardware shop ("ferreteria"). We got most of the materials from Bauhaus in Barcelona (Zona Franca). Our experience was that most of the screws, nuts and bolts are easy to substitute with others that have more or less the same dimensions.<br />
<br />
[[File:bookscanner_pseudoready2.jpg|600px]] <br />
<br />
== Budget ==<br />
<br />
Kunlabora event was four days of collaborative construction. More or less six persons worked on building the scanner. This is the receipts that we spent, because we had 500 EUR budget for the raw materials from the participation fee of the event. <br />
<br />
Receipts:<br />
<br />
25 2x plexiglass [J] @ Expocryl, Igualada<br />
18 2x SD cards @ Life Informatica, Barcelona<br />
50 2x magic want camera stand @ FotoK, Barcelona<br />
42.2 Nuts/bolts/etc. @ Bauhaus, Zona Franca, Barcelona<br />
108.8 Nuts/bolts/etc. @ Bauhaus, Zona Franca, Barcelona<br />
10 2x USB cable male/female @ Worten San Antoni, Barcelona<br />
5 2x mini USB (USB-B) cable @ Tienda Cables, Barcelona<br />
178 2x Canon IXUS 175 compact digital camera @ Amazon.es<br />
60 4x Wooden beams (listones) @ Fustes Fargas, Barcelona<br />
============================================<br />
497<br />
<br />
Donations:<br />
<br />
70 Raspberry Pi 3 (Model B), 2x SD cards, 5V charger, rulers [M] @ Barcelona<br />
<br />
We also used nuts and bolts, etc. found in the workshop of Calafou (in Catalunya, near Barcelona). The conclusion is that it should be possible to build this scanner from about 5-600 EUR anywhere in (Western) Europe. We did not use all the materials we bought and if we would do it again then we tried to use real wood instead of FDM, because the latter proved very fragile. However, this could make the platen more heavy, and it is already quite heavy.<br />

<br />
<b>Things to take in consideration from the building experience</b><br />
<br />
* the MDF pieces are fragile and gave us problems when introducing screws<br />
* we considered varnishing the wood pieces to limit humidity impact<br />
* the plexiglas we bought generates many reflections<br />
* passing from inches to cm was uncomfortable<br />
* the position and height of the light should be tested before being fixed<br />
* the upper part of the light stand should be easier to mount and unmount for transportation<br />
* the wood used for the platen should be without texture or painted with mate dark paint<br />
* the gooseneck option for the camera stand is not a good option: it is very easy to put the camera in the way of the cradle; the calibration process is difficult because the cameras can move in the three axis; they are springy and difficult to set in an exact position<br />
<br />
== Cameras ==<br />
<br />
The bookscanner is basically a glorified camera stand that allows us to take good pictures of book pages. So the cameras are an important part of the bookscanner. Summary of research about cameras for book scanners:<br />
<br />
Basically there are three categories of cameras that can be used for book scanners (from cheapest to most expensive).<br />
<br />
1. Remote control support<br />
<br />
The cheapest option is any camera with remote trigger support, so we can take pictures without pushing the button on the camera. This is important because when you press the button the camera position may be disadjusted to the physical pressure.<br />
<br />
2. CHDK firmware<br />
<br />
Middle category is CHDK firmware compatibles. CHDK is a third party open source firmware that allows the customisation of cameras. CHDK firmware is for Canon Powershot cameras, which are the cheaper compact digital camera product line. We have 200 euros in the budget for cameras, so we went with this option.<br />
<br />
3. Magic Lantern support<br />
<br />
Magic Lantern is a third party open source firmware that is more advanced. However, it only works with Canon DLSR cameras (these are the cameras that have a reflex mirror to look at the shot through a small hole before you take the picture, and they usually have big lenses). The scanner we have now uses Canon 1100D, which are the cheapest type suported by Magic Lantern, but they still cost a few hundred euros.<br />

= Building a "New Standard Scanner" =<br />
<br />
We built this: https://forum.diybookscanner.org/viewtopic.php?f=1&t=333 during the Kunlabora event in Calafou: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative A more reproducible and portable and simple scanner.<br />
<br />
In theory for the simple scanner it should be possible to get all the ingredients from a hardware shop ("ferreteria"). We got most of the materials from Bauhaus in Barcelona (Zona Franca). Our experience was that most of the screws, nuts and bolts are easy to substitute with others that have more or less the same dimensions.<br />
<br />

<br />
== Budget ==<br />
<br />
Kunlabora event was four days of collaborative construction. More or less six persons worked on building the scanner. This is the receipts that we spent, because we had 500 EUR budget for the raw materials from the participation fee of the event. <br />
<br />
Receipts:<br />
<br />
25 2x plexiglass [J] @ Expocryl, Igualada<br />
18 2x SD cards @ Life Informatica, Barcelona<br />
50 2x magic want camera stand @ FotoK, Barcelona<br />

10 2x USB cable male/female @ Worten San Antoni, Barcelona<br />
5 2x mini USB (USB-B) cable @ Tienda Cables, Barcelona<br />
178 2x Canon IXUS 175 compact digital camera @ Amazon.es<br />

<br />
Donations:<br />
<br />
70 Raspberry Pi 3 (Model B), 2x SD cards, 5V charger, rulers [M] @ Barcelona<br />
<br />
We also used nuts and bolts, etc. found in the workshop of Calafou (in Catalunya, near Barcelona). The conclusion is that it should be possible to build this scanner from about 5-600 EUR anywhere in (Western) Europe. We did not use all the materials we bought and if we would do it again then we tried to use real wood instead of FDM, because the latter proved very fragile. However, this could make the platen more heavy, and it is already quite heavy.<br />

<b>Things to take in consideration from the building experience</b><br />
<br />
* the MDF pieces are fragile and gave us problems when introducing screws<br />
* we considered varnishing the wood pieces to limit humidity impact<br />
* the plexiglas we bought generates many reflections<br />
* passing from inches to cm was uncomfortable<br />
* the position and height of the light should be tested before being fixed<br />
* the upper part of the light stand should be easier to mount and unmount for transportation<br />
* the wood used for the platen should be without texture or painted with mate dark paint <br />

== Cameras ==<br />
<br />
The bookscanner is basically a glorified camera stand that allows us to take good pictures of book pages. So the cameras are an important part of the bookscanner. Summary of research about cameras for book scanners:<br />
<br />
Basically there are three categories of cameras that can be used for book scanners (from cheapest to most expensive).<br />
<br />
1. Remote control support<br />
<br />
The cheapest option is any camera with remote trigger support, so we can take pictures without pushing the button on the camera. This is important because when you press the button the camera position may be disadjusted to the physical pressure.<br />
<br />
2. CHDK firmware<br />
<br />
Middle category is CHDK firmware compatibles. CHDK is a third party open source firmware that allows the customisation of cameras. CHDK firmware is for Canon Powershot cameras, which are the cheaper compact digital camera product line. We have 200 euros in the budget for cameras, so we went with this option.<br />
<br />
3. Magic Lantern support<br />
<br />
Magic Lantern is a third party open source firmware that is more advanced. However, it only works with Canon DLSR cameras (these are the cameras that have a reflex mirror to look at the shot through a small hole before you take the picture, and they usually have big lenses). The scanner we have now uses Canon 1100D, which are the cheapest type suported by Magic Lantern, but they still cost a few hundred euros.<br />

= Raspberry Pi for the bookscanner =<br />
<br />
At the moment we use an electromechanical button documented on the CHDK website that works well but does not do much more than triggering the two cameras to shoot at the same time: http://chdk.wikia.com/wiki/USB_Remote<br />
<br />
There are many more possibilities of how to optimise the bookscanning process. Many ideas start with connecting the cameras to a small computer such as the Raspberry Pi. We made some experiments and tests with this setup, which is documented below:<br />
<br />
It runs [https://www.raspbian.org/ Raspbian].<br />
<br />
== CHDKPTP ==<br />
<br />
In /home/pi/chdkptp there are precompiled binaries of [https://app.assembla.com/spaces/chdkptp/wiki CHDKPTP] downloaded from [https://app.assembla.com/spaces/chdkptp/documents here].<br />
<br />
CHDKPTP is used for remote control of camera running CHDK firmware.<br />
<br />
Our setup has two modes of work:<br />
* mechanical "button" which triggers both camera capturing its photo based on this tutorial: http://chdk.wikia.com/wiki/USB_Remote<br />
* (in progress) Raspberry Pi mode where an bookscanner operator uses Raspberry Pi to capture photos, preview photos in real time and transfer them already renamed for the next step in Scantailor.<br />
<br />
When camera is connected this line will list info about the camera e.g.:<br />
<nowiki>sudo ./chdkptp.sh -elist</nowiki><br />
and for one of the camera this is what is listed then:<br />
<nowiki>-1:Canon IXUS 175 b=001 d=030 v=0x4a9 p=0x32c1 s=8B20D62641B041BAA3E1D597D560D110</nowiki><br />
<br />
An example of capturing a picture from commandline (once in /home/pi/chdkptp/):<br />
<nowiki>sudo ./chdkptp.sh -e"connect -d=030" -erec -eshoot</nowiki><br />
Above line connects to the camera sitting on -d=021, puts it into rec mode (if not already) and capture the photo saving it to SD card already in camera. If one wants to bypass the SD card altogether it should replace -eshoot with -eremoteshoot. In that case ./chdkptp.sh will save photos into the directory from where it was called.<br />
<br />
Note: check the SD card is locked.<br />
<br />
== ZeroTier ==<br />
<br />
It is added to 565799d8f6ebf1a8 public network of [https://zerotier.com ZeroTier] with this command:<br />
<nowiki>sudo zerotier-cli join 565799d8f6ebf1a8</nowiki><br />
and it got static IP address (in 565799d8f6ebf1a8 network):<br />
<nowiki>192.168.192.171/24</nowiki><br />
<br />
In /home/pi/.ssh/authorized_keys public keys of maxigas and marcell are added.<br />
<br />
= Ideas for building Voja's scanner =<br />
<br />
Our first idea was to reproduce Voja's scanner but we had to realise that we are not Voja and the scanner is very beautiful and unique engineering and consequently it is hard to reproduce. <br />
<br />
Here are two links to the public documentation of our scanner, built by Voja Antonic:<br />
<br />
https://www.memoryoftheworld.org/blog/2012/10/28/our-beloved-bookscanner-2/<br />
<br />
https://hackaday.io/project/5604-diy-book-scanner<br />
<br />
The electronics is not really documented (which means that it is hard to reproduce) and it is built from basic parts (which means that it takes a lot of time to put it together). So we brainstorm about an Arduino-based solution instead. Arduino is a general-purpose programmable microcontroller that has already built-in many of the functions/parts we need. The idea is that this makes it easier for us to build the scanner and for others to reproduce it. We also have more experience working with Arduino than with only basic electronic components. <br />
<br />
We will also try to use cheaper cameras in order to bring down the budget.<br />

<hr />
<div>Bookscanning in Calafou:<br />
<br />
* We made an event called Hack the Biblio: Let's make Digital Public Libraries in 2014 as a collaboration with memoryoftheworld, when Voja Antonic donated a bookscanner to Calafou: https://calafou.org/en/content/hack-biblio-construir-bibliotecas-publicas https://calafou.org/en/content/voja-antonic-calafou<br />
* We scan out of print books published by Virus: http://www.viruseditorial.net/<br />
* We built a book scanner in 2018 during the Kunlabora event for supporting other collectives that want to scan: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative<br />

<br />
There are many more possibilities of how to optimise the bookscanning process. Many ideas start with connecting the cameras to a small computer such as the Raspberry Pi. We made some experiments and tests with this setup, which is documented below:<br />
<br />
It runs [https://www.raspbian.org/ Raspbian].<br />
<br />
== CHDKPTP ==<br />
<br />
In /home/pi/chdkptp there are precompiled binaries of [https://app.assembla.com/spaces/chdkptp/wiki CHDKPTP] downloaded from [https://app.assembla.com/spaces/chdkptp/documents here].<br />
<br />
CHDKPTP is used for remote control of camera running CHDK firmware.<br />
<br />
Our setup has two modes of work:<br />
* mechanical "button" which triggers both camera capturing its photo based on this tutorial: http://chdk.wikia.com/wiki/USB_Remote<br />
* (in progress) Raspberry Pi mode where an bookscanner operator uses Raspberry Pi to capture photos, preview photos in real time and transfer them already renamed for the next step in Scantailor.<br />
<br />
When camera is connected this line will list info about the camera e.g.:<br />
<nowiki>sudo ./chdkptp.sh -elist</nowiki><br />
and for one of the camera this is what is listed then:<br />
<nowiki>-1:Canon IXUS 175 b=001 d=030 v=0x4a9 p=0x32c1 s=8B20D62641B041BAA3E1D597D560D110</nowiki><br />
<br />
An example of capturing a picture from commandline (once in /home/pi/chdkptp/):<br />
<nowiki>sudo ./chdkptp.sh -e"connect -d=030" -erec -eshoot</nowiki><br />
Above line connects to the camera sitting on -d=021, puts it into rec mode (if not already) and capture the photo saving it to SD card already in camera. If one wants to bypass the SD card altogether it should replace -eshoot with -eremoteshoot. In that case ./chdkptp.sh will save photos into the directory from where it was called.<br />
<br />
Note: check the SD card is locked.<br />

= Ideas for building Voja's scanner =<br />
<br />
Our first idea was to reproduce Voja's scanner but we had to realise that we are not Voja and the scanner is very beautiful and unique engineering and consequently it is hard to reproduce. <br />
<br />
Here are two links to the public documentation of our scanner, built by Voja Antonic:<br />
<br />
https://www.memoryoftheworld.org/blog/2012/10/28/our-beloved-bookscanner-2/<br />
<br />
https://hackaday.io/project/5604-diy-book-scanner<br />
<br />
The electronics is not really documented (which means that it is hard to reproduce) and it is built from basic parts (which means that it takes a lot of time to put it together). So we brainstorm about an Arduino-based solution instead. Arduino is a general-purpose programmable microcontroller that has already built-in many of the functions/parts we need. The idea is that this makes it easier for us to build the scanner and for others to reproduce it. We also have more experience working with Arduino than with only basic electronic components. <br />
<br />
We will also try to use cheaper cameras in order to bring down the budget.<br />

<div>Bookscanning in Calafou:<br />
<br />
* We made an event called Hack the Biblio: Let's make Digital Public Libraries in 2014 as a collaboration with memoryoftheworld, when Voja Antonic donated a bookscanner to Calafou: https://calafou.org/en/content/hack-biblio-construir-bibliotecas-publicas https://calafou.org/en/content/voja-antonic-calafou<br />
* We scan out of print books published by Virus: http://www.viruseditorial.net/<br />
* We built a book scanner in 2018 during the Kunlabora event for supporting other collectives that want to scan: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative<br />
<br />
This page is documenting the design and construction of bookscanners. For the tutorial that explains "How to use the bookscanner", go to http://wiki.calafou.org/index.php/Bookscanning<br />
<br />
= Building a "New Standard Scanner" =<br />
<br />
We built this: https://forum.diybookscanner.org/viewtopic.php?f=1&t=333 during the Kunlabora event in Calafou: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative A more reproducible and portable and simple scanner.<br />
<br />
In theory for the simple scanner it should be possible to get all the ingredients from a hardware shop ("ferreteria"). We got most of the materials from Bauhaus in Barcelona (Zona Franca). Our experience was that most of the screws, nuts and bolts are easy to substitute with others that have more or less the same dimensions.<br />
<br />
[[File:bookscanner_pseudoready2.jpg|600px]] <br />
<br />
== Budget ==<br />
<br />
Kunlabora event was four days of collaborative construction. More or less six persons worked on building the scanner. This is the receipts that we spent, because we had 500 EUR budget for the raw materials from the participation fee of the event. <br />
<br />
Receipts:<br />
<br />
25 2x plexiglass [J] @ Expocryl, Igualada<br />
18 2x SD cards @ Life Informatica, Barcelona<br />
50 2x magic want camera stand @ FotoK, Barcelona<br />
42.2 Nuts/bolts/etc. @ Bauhaus, Zona Franca, Barcelona<br />
108.8 Nuts/bolts/etc. @ Bauhaus, Zona Franca, Barcelona<br />
10 2x USB cable male/female @ Worten San Antoni, Barcelona<br />
5 2x mini USB (USB-B) cable @ Tienda Cables, Barcelona<br />
178 2x Canon IXUS 175 compact digital camera @ Amazon.es<br />
60 4x Wooden beams (listones) @ Fustes Fargas, Barcelona<br />

497<br />
<br />
Donations:<br />
<br />
70 Raspberry Pi 3 (Model B), 2x SD cards, 5V charger, rulers [M] @ Barcelona<br />
<br />
We also used nuts and bolts, etc. found in the workshop of Calafou (in Catalunya, near Barcelona). The conclusion is that it should be possible to build this scanner from about 5-600 EUR anywhere in (Western) Europe. We did not use all the materials we bought and if we would do it again then we tried to use real wood instead of FDM, because the latter proved very fragile. However, this could make the platen more heavy, and it is already quite heavy.<br />

== Cameras ==<br />
<br />
The bookscanner is basically a glorified camera stand that allows us to take good pictures of book pages. So the cameras are an important part of the bookscanner. Summary of research about cameras for book scanners:<br />
<br />
Basically there are three categories of cameras that can be used for book scanners (from cheapest to most expensive).<br />
<br />
1. Remote control support<br />
<br />
The cheapest option is any camera with remote trigger support, so we can take pictures without pushing the button on the camera. This is important because when you press the button the camera position may be disadjusted to the physical pressure.<br />
<br />
2. CHDK firmware<br />
<br />
Middle category is CHDK firmware compatibles. CHDK is a third party open source firmware that allows the customisation of cameras. CHDK firmware is for Canon Powershot cameras, which are the cheaper compact digital camera product line. We have 200 euros in the budget for cameras, so we went with this option.<br />
<br />
3. Magic Lantern support<br />
<br />
Magic Lantern is a third party open source firmware that is more advanced. However, it only works with Canon DLSR cameras (these are the cameras that have a reflex mirror to look at the shot through a small hole before you take the picture, and they usually have big lenses). The scanner we have now uses Canon 1100D, which are the cheapest type suported by Magic Lantern, but they still cost a few hundred euros.<br />

= Ideas for building Voja's scanner =<br />
<br />
Our first idea was to reproduce Voja's scanner but we had to realise that we are not Voja and the scanner is very beautiful and unique engineering and consequently it is hard to reproduce. <br />
<br />
Here are two links to the public documentation of our scanner, built by Voja Antonic:<br />
<br />
https://www.memoryoftheworld.org/blog/2012/10/28/our-beloved-bookscanner-2/<br />
<br />
https://hackaday.io/project/5604-diy-book-scanner<br />
<br />
The electronics is not really documented (which means that it is hard to reproduce) and it is built from basic parts (which means that it takes a lot of time to put it together). So we brainstorm about an Arduino-based solution instead. Arduino is a general-purpose programmable microcontroller that has already built-in many of the functions/parts we need. The idea is that this makes it easier for us to build the scanner and for others to reproduce it. We also have more experience working with Arduino than with only basic electronic components. <br />
<br />
We will also try to use cheaper cameras in order to bring down the budget.<br />

<hr />
<div>There are many ways to scan, this is the current state of the art in Calafou. We use only free software and the documentation is for Debian GNU/Linux, but it should work with some small modifications on any UNIX based system running the bash shell. There are some parts where proprietary software such as ABBYY FineReader can be more effective. However, this workflow produces near perfect books in PDF format that we are very happy with. One thing we could definitely improve is the size of the final PDF file, which is quite big (can be more than 100 megabytes).<br />
<br />
= Scanning =<br />
<br />
'''The amount of work in the postproduction phase depends on how good quality images you can make in the scanning phase!'''<br />
<br />
# Setting up the cameras (calibration): the most important part.<br />
<br />
* open the book in the middle (at a central page with normal text on both sides)<br />
* '''camera should look directly on the middle of the page, parallel to the cradle, at 45 degrees compared to horizontal'''<br />
* all the page should be in the image, but it is not a problem if more things outside of the book are visible<br />
* check if the pages fold/curve; if so, place something underneath to straighten it (like a sponge, or another book…)<br />
* camera settings: fully automatic, perhaps with manual focus<br />
* back up and empty the SD cards in the cameras<br />
* most subtle mistake: one camera sees letters bigger than the other camera (this can be a difference in the zoom level or the distance between camera and page)<br />
* use a post-it or similar to mark the exact position of the book in relation to the lower edge of the cradle, to ensure it remains in the same position throughout the scanning<br />
<br />
<ol start="2" style="list-style-type: decimal;"><br />
<li>Push the big button on the scanner to scan.</li></ol><br />
<br />
* maybe you have to put your finger to the side of the plexiglass which is closer to you when it is “down”, because the plexiglass is not always exactly the same angle as the book pages<br />
<br />
<ol start="3" style="list-style-type: decimal;"><br />
<li>Download the images from the SD cards and put the scanner to sleep.</li></ol><br />
<br />
* from the camera on the left, copy the images to a folder called “odd”<br />
* from the camera on the right, copy the images to a folder called “even”<br />
* upload the two folders now to to <code>ftp://omnius.calafou/HackTheBiblio/scanning/$bookname--$yourname/</code> folder<br />
* remember to delete the pictures from the SD cards and put them back to the cameras, and maybe put the camera batteries to charge<br />
<br />
'''Additional information using the Marron scanner'''<br />
<br />
* Check before starting that the SD card are locked: the external trigger that controls the cameras requires the SD cards to be locked. If they are not locked, the pictures are not saved when using the external trigger.<br />
* Camera settings: we use two IXUS 175 set to automatic with menu/lamp setting set to "off" to avoid the use of the red light<br />
* While taking pictures, if you need to check the last picture taken: long press the green play button to enter slideshow mode, long press the green play button to go back to picture mode (half pressure on the camera trigger also works)<br />
* If you decide to use the zoom of the camera (not the digital zoom), be careful not to turn off the camera or you will loose your zoom setting<br />
<br />
= Dependencies =<br />
<br />
Using an up-to-date Debian operating system, you can install the following programs for the postproduction steps:<br />
<br />
* scantailor<br />
* gprename<br />
* pdftk<br />
* tesseract-ocr<br />
* tesseract-ocr-eng<br />
* tesseract-ocr-spa<br />
* calibre<br />
<br />
You can install all these programs with the following invocation from the command line (also called the terminal):<br />
<br />
<pre>sudo apt install scantailor gprename pdftk tesseract-ocr /<br />
tesseract-ocr-eng tesseract-ocr-spa calibre</pre><br />
<br />
= Postproduction =<br />
<br />
You start with two folders such as <code>odd</code> and <code>even</code> with files like IMG_1234.JPG. It is not good to talk about <code>right</code> and <code>left</code> because it can be very confusing: are you talking about the image from the right camera that takes pictures of the left page of the book, or the image of the left page of the book that is from the right camera? On the other hand, <code>odd</code> (1, 3, 5, …) and <code>even</code> (2, 4, 6, …) are good words for describing what is on the image without ambiguity!<br />
<br />
The basic workflow is like this:<br />
<br />
<ol start="0" style="list-style-type: decimal;"><br />
<li> [process] → [program] → [output]</li><br />
<li> Merge pictures from the two cameras → gprename → 1.jpg, 2.jpg, …</li><br />
<li> Edit the pictures to adjust contents → scantailor → 1.tif, 2.tif, …</li><br />
<li> Character recognition → tesseract → 1.pdf, 2.pdf, …</li><br />
<li> Create the pdf file → pdftk → book.pdf</li><br />
<li> Create the ebook → calibre → book.epub</li><br />
<li> Disseminate → libgen.org → http://libgen.org/book/index.php?md5=B6916395FDE00D91DB4F52DCB8F069BF</li><br />
<li>etc.</li></ol><br />
<br />
There are some bash oneliners which can be useful (on Debian based systems):<br />
<br />
<ol style="list-style-type: decimal;"><br />
<li><p> <code>gprename</code> <br />
* enter <code>gprename</code> using a Terminal<br />
* go to the Directory with the odd files<br />
* select all files<br />
* go to the numerical tab<br />
* set starting number to 1 and increment by 2<br />
* set the naming pattern<br />
<br />
[[File:Gprename.png|gprename window for renaming files]]<br />
<br />
* repeat the operation for even files<br />
* merge the two folders<br />
* <code>FIXME</code> we can probably write a script to rename the files properly…</p></li><br />
<li><p> <code> scantailor </code></p><br />
<br />
<br />
<br />
<br />
<p>You can rotate the images appropriately (which is called “fix orientation” in scantailor) in the left/right folders before you import them. This is faster than in <code>scantailor</code> I think. However, you can also make the same operation in <code>scantailor</code> in a more user friendly way.</p><br />
<pre> sudo apt-get install imagemagick<br />
cd odd<br />
mogrify -verbose -rotate 270 *<br />
cd ../even<br />
mogrify -verbose -rotate 90 *</pre></li><br />
<li><p>Does Optical Character Recognition (OCR) on all images in folder:</p><br />
<pre> time for i in *tif; do b=$(basename $i .tif); tesseract -l spa &quot;$i&quot; &quot;$b&quot; pdf; done</pre></li><br />
<li><p>Merges all the pdf files in folder into one single file:</p><br />
<pre> pdftk *pdf cat output book.pdf</pre></li><br />
<li><p>Exports the pdf metadata to a text file, to edit:</p><br />

<div>There are many ways to scan, this is the current state of the art in Calafou. We use only free software and the documentation is for Debian GNU/Linux, but it should work with some small modifications on any UNIX based system running the bash shell. There are some parts where proprietary software such as ABBYY FineReader can be more effective. However, this workflow produces near perfect books in PDF format that we are very happy with. One thing we could definitely improve is the size of the final PDF file, which is quite big (can be more than 100 megabytes).<br />
<br />
= Scanning =<br />
<br />
'''The amount of work in the postproduction phase depends on how good quality images you can make in the scanning phase!'''<br />
<br />
# Setting up the cameras (calibration): the most important part.<br />
<br />
* open the book in the middle (at a central page with normal text on both sides)<br />
* '''camera should look directly on the middle of the page, parallel to the cradle, at 45 degrees compared to horizontal'''<br />
* all the page should be in the image, but it is not a problem if more things outside of the book are visible<br />
* check if the pages fold/curve; if so, place something underneath to straighten it (like a sponge, or another book…)<br />
* camera settings: fully automatic, perhaps with manual focus<br />
* back up and empty the SD cards in the cameras<br />
* most subtle mistake: one camera sees letters bigger than the other camera (this can be a difference in the zoom level or the distance between camera and page)<br />
* use a post-it or similar to mark the exact position of the book in relation to the lower edge of the cradle, to ensure it remains in the same position throughout the scanning<br />
<br />
<ol start="2" style="list-style-type: decimal;"><br />
<li>Push the big button on the scanner to scan.</li></ol><br />
<br />
* maybe you have to put your finger to the side of the plexiglass which is closer to you when it is “down”, because the plexiglass is not always exactly the same angle as the book pages<br />
<br />
<ol start="3" style="list-style-type: decimal;"><br />
<li>Download the images from the SD cards and put the scanner to sleep.</li></ol><br />
<br />
* from the camera on the left, copy the images to a folder called “odd”<br />
* from the camera on the right, copy the images to a folder called “even”<br />
* upload the two folders now to to <code>ftp://omnius.calafou/HackTheBiblio/scanning/$bookname--$yourname/</code> folder<br />
* remember to delete the pictures from the SD cards and put them back to the cameras, and maybe put the camera batteries to charge<br />
<br />
'''Additional information using the Marron scanner'''<br />
<br />
* Check before starting that the SD card are locked: the external trigger that controls the cameras requires the SD cards to be locked. If they are not locked, the pictures are not saved when using the external trigger.<br />
* Camera settings: we use two IXUS 175 set to automatic with menu/lamp setting set to "off" to avoid the use of the red light<br />
* While taking pictures, if you need to check the last picture taken: long press the green play button to enter slideshow mode, long press the green play button to go back to picture mode (half pressure on the camera trigger also works)<br />
* If you decide to use the zoom of the camera (not the digital zoom), be careful not to turn off the camera or you will loose your zoom setting<br />
<br />

<br />
Using an up-to-date Debian operating system, you can install the following programs for the postproduction steps:<br />
<br />
* scantailor<br />
* gprename<br />
* pdftk<br />
* tesseract-ocr<br />
* tesseract-ocr-eng<br />
* tesseract-ocr-spa<br />
* calibre<br />
<br />
You can install all these programs with the following invocation from the command line (also called the terminal):<br />
<br />
<pre>sudo apt install scantailor gprename pdftk tesseract-ocr /<br />
tesseract-ocr-eng tesseract-ocr-spa calibre</pre><br />
<br />
= Postproduction =<br />
<br />
You start with two folders such as <code>odd</code> and <code>even</code> with files like IMG_1234.JPG. It is not good to talk about <code>right</code> and <code>left</code> because it can be very confusing: are you talking about the image from the right camera that takes pictures of the left page of the book, or the image of the left page of the book that is from the right camera? On the other hand, <code>odd</code> (1, 3, 5, …) and <code>even</code> (2, 4, 6, …) are good words for describing what is on the image without ambiguity!<br />
<br />
The basic workflow is like this:<br />
<br />
<ol start="0" style="list-style-type: decimal;"><br />
<li> [process] → [program] → [output]</li><br />
<li> Merge pictures from the two cameras → gprename → 1.jpg, 2.jpg, …</li><br />
<li> Edit the pictures to adjust contents → scantailor → 1.tif, 2.tif, …</li><br />
<li> Character recognition → tesseract → 1.pdf, 2.pdf, …</li><br />
<li> Create the pdf file → pdftk → book.pdf</li><br />
<li> Create the ebook → calibre → book.epub</li><br />
<li> Disseminate → libgen.org → http://libgen.org/book/index.php?md5=B6916395FDE00D91DB4F52DCB8F069BF</li><br />
<li>etc.</li></ol><br />
<br />
There are some bash oneliners which can be useful (on Debian based systems):<br />
<br />
<ol style="list-style-type: decimal;"><br />
<li><p> gprename<br />
* enter gprename using a Terminal<br />
* go to the Directory with the odd files<br />
* select all files<br />
* go to the numerical tab<br />
* set starting number to 1 and increment by 2<br />
* set the naming pattern<br />
[[File:Gprename.jpg|frameless|gprename window for renaming pictures]]<br />
<br />
<code>FIXME</code> we can probably write a script to rename the files properly… but for now, in <code>gprename</code> select the “numberical” tab, start = 1 for odd pages and 2 for even pages, always step = 2.</p></li><br />
<li><p>You can rotate the images appropriately (which is called “fix orientation” in scantailor) in the left/right folders before you import them. This is faster than in <code>scantailor</code> I think. However, you can also make the same operation in <code>scantailor</code> in a more user friendly way.</p><br />
<pre> sudo apt-get install imagemagick<br />
cd odd<br />
mogrify -verbose -rotate 270 *<br />
cd ../even<br />
mogrify -verbose -rotate 90 *</pre></li><br />
<li><p>Does Optical Character Recognition (OCR) on all images in folder:</p><br />
<pre> time for i in *tif; do b=$(basename $i .tif); tesseract -l spa &quot;$i&quot; &quot;$b&quot; pdf; done</pre></li><br />
<li><p>Merges all the pdf files in folder into one single file:</p><br />
<pre> pdftk *pdf cat output book.pdf</pre></li><br />
<li><p>Exports the pdf metadata to a text file, to edit:</p><br />

<li><p>Imports the metadata of report.txt back to the PDF:</p><br />

Using an up-to-date Debian operating system, you can install the following programs for the postproduction steps:<br />
<br />
* scantailor<br />
* gprename or KRename<br />
* pdftk<br />
* tesseract-ocr<br />
* tesseract-ocr-eng<br />
* tesseract-ocr-spa<br />
* calibre<br />
<br />
You can install all these programs with the following invocation from the command line (also called the terminal):<br />
<br />
<pre>sudo apt install scantailor KRename gprename pdftk tesseract-ocr /<br />
tesseract-ocr-eng tesseract-ocr-spa calibre</pre><br />
<br />

<br />
You start with two folders such as <code>odd</code> and <code>even</code> with files like IMG_1234.JPG. It is not good to talk about <code>right</code> and <code>left</code> because it can be very confusing: are you talking about the image from the right camera that takes pictures of the left page of the book, or the image of the left page of the book that is from the right camera? On the other hand, <code>odd</code> (1, 3, 5, …) and <code>even</code> (2, 4, 6, …) are good words for describing what is on the image without ambiguity!<br />
<br />
The basic workflow is like this:<br />
<br />
<ol start="0" style="list-style-type: decimal;"><br />
<li> [process] → [program] → [output]</li><br />
<li> Merge pictures from the two cameras → gprename → 1.jpg, 2.jpg, …</li><br />
<li> Edit the pictures to adjust contents → scantailor → 1.tif, 2.tif, …</li><br />
<li> Character recognition → tesseract → 1.pdf, 2.pdf, …</li><br />
<li> Create the pdef file → pdftk → book.pdf</li><br />
<li> Create the ebook → calibre → book.epub</li><br />
<li> Disseminate → libgen.org → http://libgen.org/book/index.php?md5=B6916395FDE00D91DB4F52DCB8F069BF</li><br />
<li>etc.</li></ol><br />
<br />
There are some bash oneliners which can be useful (on Debian based systems):<br />
<br />
<ol style="list-style-type: decimal;"><br />
<li><p><code>FIXME</code> we can probably write a script to rename the files properly… but for now, in <code>gprename</code> select the “numberical” tab, start = 1 for odd pages and 2 for even pages, always step = 2.</p></li><br />
<li><p>You can rotate the images appropriately (which is called “fix orientation” in scantailor) in the left/right folders before you import them. This is faster than in <code>scantailor</code> I think. However, you can also make the same operation in <code>scantailor</code> in a more user friendly way.</p><br />

<div>There are many ways to scan, this is the current state of the art in Calafou. We use only free software and the documentation is for Debian GNU/Linux, but it should work with some small modifications on any UNIX based system running the bash shell. There are some parts where proprietary software such as ABBYY FineReader can be more effective. However, this workflow produces near perfect books in PDF format that we are very happy with. One thing we could definitely improve is the size of the final PDF file, which is quite big (can be more than 100 megabytes).<br />

On the other hand, <code>odd</code> (1, 3, 5, …) and <code>even</code> (2, 4, 6, …) are good words for describing what is on the image without ambiguity!<br />
<br />
The basic workflow is like this:<br />
<br />
<ol start="0" style="list-style-type: decimal;"><br />
<li>[program] → [output]</li><br />
<li>gprename → 1.jpg, 2.jpg, …</li><br />
<li>scantailor → 1.tif, 2.tif, …</li><br />
<li>tesseract → 1.pdf, 2.pdf, …</li><br />
<li>pdftk → book.pdf</li><br />
<li>calibre → book.epub</li><br />
<li>libgen.org → http://libgen.org/book/index.php?md5=B6916395FDE00D91DB4F52DCB8F069BF</li><br />
<li>etc.</li></ol><br />
<br />
There are some bash oneliners which can be useful (on Debian based systems):<br />
<br />
<ol style="list-style-type: decimal;"><br />
<li><p><code>FIXME</code> we can probably write a script to rename the files properly… but for now, in <code>gprename</code> select the “numberical” tab, start = 1 for odd pages and 2 for even pages, always step = 2.</p></li><br />
<li><p>You can rotate the images appropriately (which is called “fix orientation” in scantailor) in the left/right folders before you import them. This is faster than in <code>scantailor</code> I think. However, you can also make the same operation in <code>scantailor</code> in a more user friendly way.</p><br />

<div>==Tutorial Per Instal·lar Riot==<br />
===Linux Mint===<br />
<br />
Primer he de saber quina versió de Linux Mint estic fent servir.<br />
Per aconseguir-ho cerco a Menú/Preferències/Informació del sistema<br />
<br />
En el meu cas és: Linux Mint 18.2<br />
<br />
Després vaig a veure en quina versió d'Ubuntu està basada. Ho puc veure a:<br />
<br />
https://en.wikipedia.org/wiki/Linux_Mint_version_history<br />
<br />
En el meu cas la versió 18.2, és la que du de nom en codi "Sonya" i està basada en ubuntu 16.04 de nom en codi "Xenial Xerus".<br />
<br />
Ara ja puc seguir el tutorial web:<br />
<br />
https://linuxconfig.org/install-riot-matrix-chat-client-on-debian-and-ubuntu<br />
<br />
Al fitxer /etc/apt/sources.list amb permisos de superusuari escric la següent linea:<br />
<br />
deb https://riot.im/packages/debian xenial main<br />
<br />
(ull: escric xenial perquè la meva distribució està basada en xenial, canvia xenial per la teva que has cercat com explica més amunt)<br />
<br />
<br />
Tot seguit em descarrego la clau GPG per a fer servir el repositori amb:<br />
<br />
$ wget https://riot.im/packages/keys/riot.asc<br />
<br />
I la instal·lo amb:<br />
<br />
$ sudo apt-key add riot.asc<br />
<br />
<br />
Ja està tot llest perr a la instal·lació:<br />
<br />
$ sudo apt update<br />
<br />
$ sudo apt install riot-web<br />
<br />
<br />
Si tot ha anat bé trobarem la icona de riot al menu/internet/ cliquem dues vegades i ja està, ens apareix la pàgina inicial de riot.<br />
<br />
===Debian===<br />
<br />
Primer m'assabento de quina versió de debian tinc instal·lada. Ho puc mirar al fitxer /etc/apt/sources.list amb l'ordre:<br />
<br />
$ cat /etc/apt/sources.list<br />
<br />
<br />
En el meu cas és Jessie.<br />
<br />
<br />
Modifico el fitxer /etc/apt/sources.list afegint la linea:<br />
<br />
deb https://riot.im/packages/debian jessie main<br />
<br />
<br />
Tot seguit em descarrego la clau GPG per a fer servir el repositori amb:<br />
<br />
$ wget https://riot.im/packages/keys/riot.asc<br />
<br />
<br />
I la instal·lo amb:<br />
<br />
$ sudo apt-key add riot.asc<br />
<br />
<br />
Ja està tot llest perr a la instal·lació:<br />
<br />
$ sudo apt update<br />
<br />
$ sudo apt install riot-web<br />
<br />
<br />
Si tot ha anat bé trobarem la icona de riot al menu/internet/ cliquem dues vegades i ja està, ens apareix la pàgina inicial de riot.<br />
<br />
===Ubuntu===<br />
<br />
El procés d'instal·lació és el mateix que al Linux Mint si bé és més fàcil mirar la distribució que tenim, només hem de mirar-ho al fitxer /etc/apt/sources.list<br />
<br />
I tot seguit l'editem com s'explica al tutorial per a Linux MInt.<br />
<br />
La resta de passes han de ser les mateixes.<br />
<br />
===Android===<br />
Ens podem descarregar l'app "riot" des del repositori F-Droid.<br />
<br />
Si no tenim el repositori instal·lat ens el podem instal·lar obrint la pàgina web de l'F-Droid:<br />
<br />
https://f-droid.org/<br />
<br />
i clicant allà on diu "DOWNLOAD" des d'un navegador del nostre smartphone Android.<br />
<br />
Una vegada ens hem instal·lat F-Droid. Actualitzem el repositori i cerquem i instal·lem riot seguint les instruccions de l'aplicació.<br />
<br />
==Registrar-se a Riot==<br />
<br />
Una volta hem arrencar l'aplicació a la part superior esquerra ens apareixen la opció registrar-se, cliquem i s'ens obre una finestra que ens demana mail, telefon, pais del telefon, nom d'usuari i contrasenya. Sembla que només el nom d'usuari i la contrasenya és obligat. Tanmateix si li poses el mail i el telefon els teus amics et podran trobar per ells i també pel teu nom d'usuari.<br />
<br />
Jo li he posat el nom la contrasenya i el mail, quan he clicat a registrar m'ha enviat un mail en el qual he de clicar en l'enllaç que em diu i ja estic registrat.<br />
<br />
<br />
==Accedir a la sala de Calafou==<br />
<br />
Has rebre un mail d'algú que ja hi sigui aconvidant-te.<br />
Quan rebis el mail trobaràs un enllaç per activar el grup. Clica'l. Se t'obrirà al navegador la interfície de riot, logueget a la interficie i llavors torna a clicar l'enllaç del mail. Et demanarà si vols activar el grup cliques que si i ja el tens. Marque'l com a preferit i ja està a disfrutar.<br />
<br />
==Crear una nova sala==<br />
<br />
Les noves sales es creen a partir del menú contextual sota el llistat de persones i sales i del icona "+".<br />
A la pàgina de paràmetres de la sala es pot:<br />
- decidir si la sala és pública o privada. Fer-la pública permet a persones accedir-les com a invitades sense que siguin membres.<br />
- decidir si la sala es xifrada o no<br />
- donar una direcció a la sala de tipus #MI_SALA:matrix.org (necessari per poder afegir-la a una comunitat)<br />
- gestionar els drets del membres. Per les sales privades es pot posar que els membres nous s'on admin per defecte per no haver de donar drets d'admin a cada membre nou.<br />
<br />
==La comunitat de Calafou==<br />
<br />
La comunitat de Calafou permet centralitzar totes les sales actives en relació a les activitats de Calafou.<br />
<br />
En Riot les persones s'identifiquen amb "@", les sales amb "#" i les comunitats amb "+".<br />
<br />
La direcció de la comunitat de calafou és +calafou:matrix.org.<br />
<br />
S'hi pot accedir si la comunitat és pública o per invitació.<br />
<br />
El icona corresponent és el de tres perfils de persones. Clicant aquest icona es llista totes les comunitats de les quals formem part.<br />
Clicant a l'avatar de la comunitat, es filtren les persones a les que formen part de la comunitat.<br />
Clicant el icona "#" apareix el llistat de sales de la comunitat.<br />
<br />
Per afegir una nova sala a la comunitat:<br />
- assegurar-se que la sala té una direcció (veure crear una nova sala)<br />
- fer clic al icona "#" per llistar les sales<br />
- fer clic a afegir una sala<br />
- introduir la direcció de la sala</div>Geotyrhttp://wiki.calafou.org//index.php?title=Bookscanner&diff=3105Bookscanner2018-10-14T10:23:07Z<p>Geotyr: Correct the command line for the tesseract</p>

<div>Kunlabora bookscanner building in progress right now! :) We are building this: https://forum.diybookscanner.org/viewtopic.php?f=1&t=333<br />
<br />
= Building a scanner =<br />
<br />
Here are two links to the public documentation of our scanner, built by Voja Antonic:<br />
<br />
https://www.memoryoftheworld.org/blog/2012/10/28/our-beloved-bookscanner-2/<br />
<br />
https://hackaday.io/project/5604-diy-book-scanner<br />
<br />
We are trying to build something similar during the Kunlabora event in Calafou: https://calafou.org/en/content/kunlabora-ephimeral-projects-kooperative<br />
<br />
We decided to build a more reproducible and portable and simple scanner: https://forum.diybookscanner.org/viewtopic.php?f=1&t=333<br />
<br />
In theory for the simple scanner it should be possible to get all the ingredients from a hardware shop ("ferreteria"). We got most of the materials from Bauhaus in Barcelona (Zona Franca). TODO: list of materials, sources and prices.<br />
<br />
== Ideas for the building Voja's scanner ==<br />
<br />
The electronics is not really documented (which means that it is hard to reproduce) and it is built from basic parts (which means that it takes a lot of time to put it together. So we try to use an Arduino-based solution instead. Arduino is a general-purpose programmable microcontroller that has already built-in many of the functions/parts we need. The idea is that this makes it easier for us to build the scanner and for others to reproduce it. We also have more experience working with Arduino than with only basic electronic components. <br />
<br />
We will also try to use cheaper cameras in order to bring down the budget.<br />
<br />

== Cameras ==<br />
<br />
Summary of research about cameras for book scanners:<br />
<br />
Basically there are three categories of cameras that can be used for book scanners (from cheapest to most expensive).<br />
<br />
1. Remote control support<br />
<br />
The cheapest option is any camera with remote trigger support, so we can take pictures without pushing the button on the camera. This is important because when you press the button the camera position may be disadjusted to the physical pressure.<br />
<br />
2. CHDK firmware<br />
<br />
Middle category is CHDK firmware compatibles. CHDK is a third party open source firmware that allows the customisation of cameras. CHDK firmware is for Canon Powershot cameras, which are the cheaper compact digital camera product line. We have 200 euros in the budget for cameras, so we went with this option.<br />
<br />
3. Magic Lantern support<br />
<br />
Magic Lantern is a third party open source firmware that is more advanced. However, it only works with Canon DLSR cameras (these are the cameras that have a reflex mirror to look at the shot through a small hole before you take the picture, and they usually have big lenses). The scanner we have now uses Canon 1100D, which are the cheapest type suported by Magic Lantern, but they still cost a few hundred euros.<br />

= Scanning =<br />
<br />
'''The amount of work in the postproduction phase depends on how good quality images you can make in the scanning phase!'''<br />
<br />
# Setting up the cameras: the most important part.<br />
<br />
Caveats:<br />
<br />
* camera should look at right angle on the page<br />
* all the page should be in the image<br />
* camera settings: full automatic, perhaps with manual focus<br />
* back up and empty the SD cards in the cameras<br />
* most subtle mistake: one camera sees letters bigger than the other camera<br />
<br />
<ol start="2" style="list-style-type: decimal;"><br />
<li>Push the big button on the scanner to scan.</li></ol><br />
<br />
* maybe you have to put your finger to the side of the plexiglass which is closer to you when it is “down”, because the plexiglass is not always exactly the same angle as the book pages<br />
<br />
<ol start="3" style="list-style-type: decimal;"><br />
<li>Download the images from the SD cards and put the scanner to sleep.</li></ol><br />
<br />
* from the camera on the left, copy the images to a folder called “odd”<br />
* from the camera on the right, copy the images to a folder called “even”<br />
* upload the two folders now to to ftp://seldon.calafou/HackTheBiblio/scanning/<math>bookname--</math>yourname/ folder<br />
* remember to delete the pictures from the SD cards and put them back to the cameras, and maybe put the camera batteries to charge<br />
<br />
= Dependencies =<br />
<br />
There are many ways to scan, this is the current state of the art in Calafou.<br />
<br />
Using an up-to-date Debian operating system, you can install the following programs for the postproduction steps:<br />
<br />
* scantailor<br />
* gprename<br />
* pdftk<br />
* tesseract-ocr<br />
* tesseract-ocr-eng<br />
* tesseract-ocr-spa<br />
* calibre<br />
<br />
You can install all these programs with the following invocation:<br />
<br />
<pre>sudo apt install scantailor gprename pdftk tesseract-ocr /<br />
tesseract-ocr-eng tesseract-ocr-spa calibre</pre><br />
= Postproduction =<br />
<br />
You start with two folders with files like IMG_1234.JPG<br />
<br />
The basic workflow is like this:<br />
<br />
<ol start="0" style="list-style-type: decimal;"><br />
<li>[program] ➔ [output]</li><br />
<li>gprename ➔ 1.jpg, 2.jpg, …</li><br />
<li>scantailor ➔ 1.tif, 2.tif, …</li><br />
<li>tesseract ➔ 1.pdf, 2.pdf, …</li><br />
<li>pdftk ➔ book.pdf</li><br />
<li>calibre ➔ book.epub</li><br />
<li>libgen.org ➔ http://libgen.org/book/index.php?md5=B6916395FDE00D91DB4F52DCB8F069BF</li><br />
<li>etc.</li></ol><br />
<br />
There are some bash oneliners which can be useful (on Debian based systems):<br />
<br />
<ol style="list-style-type: decimal;"><br />
<li><p><code>FIXME</code> we can probably write a script to rename the files properly… but for now, in gprename select the “numberical” tab, start = 1 for right-pages and 2 for left-pages, always step = 2.</p></li><br />
