If you’re a big fan of internet radio, UK Tech Reviews has a guide for building your own little internet radio device using a Raspberry Pi and a touchscreen. The end result here is a nice, self-contained system that includes a simple interface for playing different stations with the touchscreen.
All you really need to do is get the touch screen working, then install the radio stations you’re interested in. When it’s all complete, you get a super easy to use device that you can leave plugged into your stereo. Head over to UK Tech Review for the full guide.
