Tech & DIY / 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.
A pitch only theremin schematic designed by noted theremingineur Thierry Frenkel. Designed to be built from readily available parts and to perform well. Perfect for the hobbyist, for science fair projects, or for anyone who wants to scratch build a working theremin!
This site shows you how to build a theremin using only parts available at your local Radio Shack!
These schematics / code / layouts are for the Skywave H1 Pitch-only “Theremin”. 16 of these were built and operated in the Royal Festival Hall (South-bank arts centre) for 10 days in 2010. Includes schematic, parts list, and circuit board patterns.
Phil Nelson has shared the 1955 schematic on his antique radio website.
Pierre has built a new tube theremin design based loosely on the RCA theremin. He has graciously shared his schematic and several sample sound clips with us!
Online version of the schematic for the popular DIY theremin kit from PAiA.
Robert George supplied this schematic for his Kustom theremin, originally based on the Moog Melodia theremin.

Hand-drawn by Bob Moog, these schematics will give you insight into Prof. Theremin's original design concepts. schematic page 1, schematic page 2. Also available are the technical notes Bob Moog wrote while working on her theremin. Adrian Bontenbal also provided some additional tech notes on this circuit with details that are hard to make out from Bob's schematic as well as some bonus circuits.
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.
Art Harrison shares his latest theremin designs with the world! Be sure to check this one out for clear directions and excellent technical description.

Theremin World member Adrian Bontenbal shared this article with us detailing how he built a transistor theremin inside a wooden wine box.
"Cool Jason. This is ROSS MARSHALL.Just uploaded my old theremin videos.Plus my new TUBE THEREMIN by John Polstra- who amazingly lives off on the Lope..."
"Anyone have an idea what a 91B would be worth these days ?"
"This seems like a most worthwhile project. I am curious as to why no one has expressed any enthusiasm so far. "
"Coil in resonance."
