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.
Big Briar Etherwave Mute Switch
Ever wanted to get rid of the "pop" when you turn on your Etherwave? Arthur Harrison has developed a mute-switch for the Etherwave that will do just that. It also adds a "mute status" light which doubles as a power-on light. Here's the schematic. Don't forget to browse the rest of Art's great site!
