Wien-Bridge theremin

2002 by Arthur Harrison. 2002

This is a theremin with only a pitch control. It doesn't use any coils or hard to find integrated circuits. I think it's a good design in its class, worth trying, it might even be a good base to experiment further (like adding volume control). Arthur made some improvements in this Revision-1 diagram.
