Theremin
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.
Schematic
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

Fritzing
Actual construction resulted in difference between the fritzing layout and actual build.
