The Theremuino is an infra-red theremin. It uses an Arduino microcontroller programmed with a modified version of the Audiuno grain synth.
The performance Theremuino has an infra-red sensor for pitch, and controls for grain delays, speed and volume. It has two modes - polite and rude - which respectively sound melodic and rhythmic/noisy. It's built into an Electro-Harmonix guitar effects pedal box.
I built two simplified Theremuinos for inclusion in the Circus Kinetica bar for Secret Garden Party 2010, with the controls mounted in an old number plate.
