Retired

This used to be our MPD server in Space 2. We now have SlabPi.

Summary

Ubuntu 14.04
Default user slabbetje, with our known password
Fujitsu Siemens Amilo Pi 2515 mainboard
2Gb RAM
Hand-patched power button on micro-fine wires

Touchscreen

Putting this in /etc/X11/xorg.conf.d/99-calibration.conf used to work:

Section "InputClass"
	Identifier	"calibration"
	MatchProduct	"eGalax Inc. USB TouchController"
	Option	"Calibration"	"1890 223 1835 263"
EndSection

Stuff running

Lightdm greeter autologin

Slab will do autologin as user slabbetje. It uses the session chosen at the last manual login. Possible sessions are defined in /usr/share/xsessions. See below for possibilities. The trick to change the default is:

move the active .desktop file away
restart lightdm
go to slab and change the session on the touchscreen
log in on the touchscreen
world domination

The last chosen session will be default from now on.

Pong

A mini pong game built in python and blessings. Will attempt to display time, but throws an error every now and then due to rounding and then cycles around resetting itself. In xterm something is really borken ;). Needs some love... See /usr/share/xsessions/pong.desktop

Lights application

Chromium is autostarted in kiosk mode with a web interface for the space lights.

Gmpc

Mpd client for controlling the music. See /usr/share/xsessions/gmpc.desktop

Ubuntu / Unity

Default Ubuntu Unity stuff. See /usr/share/xsessions/ubuntu.desktop

MPD

This board runs MPD and is connected to the Nexia PM which in turn is hooked up to the amplifier and speakers.

Festival

Starting

In order to allow the !speak function of Nurdbot (which lives on tankstation) to connect to this machine, festival can be started in server mode as user slabbetje:

./start_festival.sh &

It should start after a reboot using slabbetje's crontab:

@reboot /home/slabbetje/start_festival.sh &

Access control

Basic ACL is managed in /etc/festival.scm.

Sound on next button click

The next button lying around in the space will trigger a sound. For this a script Zarya made is started with this line in slabbetjes crontab:
@reboot /home/slabbetje/next_button.py &

Doorbell

Analog to next button, line in crontab:
@reboot /home/slabbetje/doorbell.py &

Volume

Volume of mpd can be set independently of system volume (using NURDbot or mpd client). Volume of festival, doorbell and next button sound is the same as system volume and can be set using alsamixer. At the moment system volume is 100%.
