Open Theremin - Open Source Hardware Project

Open.Theremin.RC

The Open.Theremin.RC is a simple and basic theremin circuit with one pitch antenna. The oscillators are built arround a Resistor (R) and capacity (C). The circuit will run on a 9V battery and produce a triangular output signal. The circuit is good to explore the basic theremin principle of heterodyne oscillators. For a more complete theremin with pitch and volume control see the new Open.Theremin V3.
