Dave Sharples and David Glanzman from the University of Pennsylvania have developed the Joytone – a musical instrument which uses a Raspberry Pi and an Arduino, together with 57 thumb sticks. It’s an amazing project which I’ve covered before. Now Russell Barnes has conducted an interview with the pair and published it on his latest podcast. Again, if you haven’t been following the Raspi.today podcasts, you should definitely head on over there!
