This is the first version of a board based on a “Pocket Theremin” published in a Popular Science article. I’ve tested the board and it is functional. You will need to attach two variable resistors in the indicated locations. The variable resistors can be anything–playdough, photoresistors, saltwater, conventional variable resistors, etc. May want to use larger capacitors than the indicated 0.01uF–I went as high as 0.4uF. Bigger capacitors=lower frequency. Be creative!
