In my last blog entry, I talked about theremins. I've known about them for a while, and I've always found them fascinating, but I've never actually taken the plunge and bought one, despite being being tempted on many occasions (they're not that expensive).
At the same time, I've known about Arduinos for a long time, and I've always wanted an excuse to buy one, but I've never actually taken the plunge and bought one. As I'm fond of saying, an Arduino is a solution in search of a problem, and I just never found the right problem for one.
That is, until I found this website: http://www.gaudi.ch/OpenTheremin/
