In the February 1996 issue of "Electronic Musician", an article by Robert Moog, titled "Build the EM Theremin" was published. Below are the details, images and a sound file for the THEREMIN I built from that article.

Bill of Materials

Divide and Conquer

I divided the implementation of the electronics into 6 sub circuits.

• Power Supply
• Pitch Antenna Circuit
• Volume Antenna Circuit
• Variable Pitch Oscillator - Fixed Pitch Oscillator - Pitch Tuning
• Volume Oscillator - Volume Tuning
• Detector - Voltage Controlled Amplifier - VCA Processor
