Lightsaber Theremin

Synthesizer DIY guru Look Mum No Computer shows us his latest creation... a Lightsaber theremin! We're using the word "theremin" very lightly here, of course. It's more of a unique gestural instrument that looks like a lot of fun to play!

The project uses an accelerometer to map changes in rotation to pitch CV. A button on the Lightsaber toy serves as an on/off volume switch. Jump ahead to 3:25 in the video to see a performance with two of the instruments. Don't want to use it as a theremin? A position indicator on the side allows it to double as a sort of Lev-el.

Wildly swinging Lightsabers on stage... what could go wrong?
