DIY Theremin

Thursday, December 27th, 2012

Erdabyz want's to build a DIY Theremin. This is a musical instrument controlled without direct physical contact. The device has two antennas which in conjunction with the operators body (representing the capacitance) complete two LC oscillators. By moving your hands closer or farther from the antennas, pitch and volume of...

Simple optical theremin

Friday, May 4th, 2012

Here's a simple theremin-like device designed by Sacred and presented by Jameco. Unlike other theremins which vary the sound based on the user's proximity to stationary antennae, this project uses two phototransistors and a 555 timer. The theory of operation is the variation of the sound based upon the amount...

Serenading with Arduino

Wednesday, August 31st, 2011

If you want to add a geek angle to a romantic dinner, what better way than Arduino generated music? Michele Spagnuolo has coded this project for a simple, minimalistic piano-theremin generated by Arduino and Processing. The hardware consists of a SRF05 ultrasonic sensor with Echo connected to digital pin 2...

Mini theremin uses infrared proximity sensor

Thursday, July 7th, 2011

Chris writes:  It's a theremin that uses an IR proximity sensor to detect how far away a hand is, then plays a specific music note for that distance. It works quite well, checkout the demo video in the link. The purpose of this project is to build a simple but...
