David Sharples from the University of Pennsylvania needed a subject for his senior design project on his BSE degree. So, he decided he would build a musical instrument with a Raspberry Pi. The end result is the Joytone – a large pad of joysticks that play different sounds at different pitches. It’s truly an astounding project that is a thing of beauty. Read more on the Foundation’s blog or read the full account of the build over on David’s blog. There’s a video embedded below which gives you a feel for what the instrument can do.
