A quick demo of the new firmware for the midi theremin designed by the BuildBrighton hackerspace. See http://www.buildbrighton.com/wiki/Theremin for details.
Uses ultrasonic sensors hooked up to an arduino microcontroller. The arduino outputs MIDI which is then fed in to Ableton Live with an Operator synth set up.
At the moment you'll need a computer and a MIDI interface. All this thing does is send MIDI signals. You could also plug it into any MIDI sound source (e.g. a keyboard or sound module).
There's no reason why you couldn't add an oscillator circuit and hack the software a bit to make it into a proper sound source though.
