I built an AirPi Wireless Speaker. It consists of a raspberry pi, small amp circuit, powered usb hub, wifi adapter, bookshelf speaker, and a usb battery.
You simply turn it on and wait for it to boot up then you can play music from your itunes or iphone using airplay. I also have mpd and mpc installed so that androids can play music on it too.
It took about two weeks to complete and the instructions on how to install are posted below.
How-To After the break.
These instructions are for a raspberry pi running debian, I used Occidentatlis 0.2 from adafruit.
sudo apt-get update
sudo apt-get upgrade
sudo amixer cset numid=3 1
sudo apt-get install git libao-dev libssl-dev libcrypt-openssl-rsa-perl libio-socket-inet6-perl libwww-perl avahi-utils libmodule-build-perl
sudo ./Build test
sudo ./Build install
sudo make install
./shairport.pl -a AirPi (to test)
sudo cp shairport.init.sample /etc/init.d/shairport
sudo nano /etc/init.d/shairportchange
change it to look like this:
DAEMON_ARGS-w $PIDFILE -a AirPi”
sudo chmod a+x shairport
sudo update-rc.d shairport defaults
sudo ./shairport start
