The raspberry pie makes a great pandora unit.  Duct tape it to the back of a battery-powered speaker with the 3.5 plug connected and it becomes a rocking portable boombox….make sure you have a long ethernet cord though!  Here’s how assuming root@:

We first want to push the audio out to the 3.5 jack:

[code]root@raspberrypi:~# amixer cset numid=3 1[/code]

then install pianobar:

[code]root@raspberrypi:~# apt-get install pianobar[/code]

Pianobar controls are located here.
