I've built a prototype of a headless music playback object, with the help of Raspberry PI and Arduino.
The casing is based on vintage radio designs. It uses the rPi to collect and store predefined playlists and lets the user "tune" in to different radio channels based on music genres via the I/O of the Arduino.
This is my first project working with a rPI and it's proven to be a great learning experience.
