It is installed on omnious : http://radio.calafou

To install it, install dependencies :

/!\ for debian jessie, you must install postgresql-9.4 and not postgresql without -9.4 else the calendar does'nt show up /!\

PiBox

See documentation here : http://p-node.org/doc/index.php/V-2

For the moment (see troubleshouting), 2 script are launched by /etc/rc.local :

/home/pi/omnioussonification.sh 2> /home/pi/streamlog.txt >/dev/null &
/home/pi/airtimeplayer.sh 2> /home/pi/streamlog.txt >/dev/null &

omnioussonification.sh :

#!/bin/bash
while true;do
 AUDIODEV=hw:0,0 play -t ogg http://radio.calafou:8000/omniussonification.ogg.m3u
done

airtimeplayer.sh

#!/bin/bash
while true;do
 AUDIODEV=hw:1,0 play -t ogg http://radio.calafou:8000/airtime_128.m3u
done

Troubleshouting

Airtime

The main stream doesn't output sound

It happens sometimes, to repair it, you can send a master source with a streaming software and then disconnect it, the sound reappear ! ...

Airtime doesn't seems to play sound, show the media builder or eat new sounds

The 3 magic command to restart everything (you have to be logged in omnious :

sudo service airtime-media-monitor restart
sudo service airtime-liquidsoap restart
sudo service airtime-playout restart

also, see the logs in /var/log/airtime/

PiBox

For the moment (28.08.2016), this interface of pibox is not used because the python script call aplay which seems not to accept mountpoint without .ogg which is the case for the main airtime stream and I couldn't manage to modify it, so scripts are luanched instead by rc.local

Antenna

The tube on which I was planning to fix the antenna is about to fall !

So I used instead a solid metal piece fixed to the wall, but the antenna is only fixed in one point with plastic bracelets (colson) and 2 wires fixed to 2 solid metal points

I'm not sure it is really good on a long time perspective ...
