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.
The Theremin, by Robert Moog
This tube theremin article originally appeared in Radio and Television News in 1954. You might have trouble finding all the parts to build this theremin today, but the article is also an excellent source of technical information.
