The Richmond Area Gear Expo (RAGE!) was an eclectic mix of luthiers, guitar pedal makers, and talented musicians. I had a table with some noise instruments (Von Braun VIII and X, reporting for duty) and my ring mod guitar. I was invited by Natalie Quick, who works at Fan Guitar and Ukulele, a great store… Continue Reading →
Last weekend, I went to my first Maker Faire! Maker Faires, known as “The Greatest Show and Tell on Earth”, are events hosted or sponsored by Make Magazine where Makers gather to show off what they are working on. There are generally a small number of “Flagship Maker Faires” (hosted in San Francisco, Detroit, and… Continue Reading →
The Challenger II is a an optical theremin named after the Space Shuttle Challenger. I built the Challenger II in 2008 along with the Challenger I, which was a similar optical theremin. Challenger I was given away to a local musician shortly after being built. The Challenger II uses a 555 IC oscillator circuit. Pitch… Continue Reading →
The Vostok I is a 555 oscillator circuit with a pair of touch-sensitive antennae that control the frequency of the oscillator. The entire contact theremin is housed in the lower half of a cigar box. The only user control aside from the antennae is the power switch located on the control panel. This small instrument… Continue Reading →

The optic sensor also doubles as an oscillator, and the output is hardwired into a stereo amplifier, which is fed into the 3 speakers… Continue Reading →
