Theremin Schematics
Here's a list of various types of theremin schematics. You'll find tube theremins, transistor theremins, optical theremins, beginner, and advanced projects. If you're not sure where to start, we suggest reading through our theremin construction forum to get an idea of which schematic might be best for you.
Note, we've moved schematics and technical information for RCA theremins and the Keppinger theremins to their own pages.

This is a demo of Forrest Mims, III’s Audible Light Meter. This photo-theremin design was originally published in Optoelectronic Projects Vol 1, published by Radio Shack in 1976.
LEGO Optical Theremin
Build an optical theremin out of LEGOs! Step by step instructions, schematics, and a demonstration video are provided.
Build Squaremin as a form of theremin
An optical theremin using IR sensors to control pitch and octave (instead of pitch and volume).
