We were excited to learn of [Omer Yosha]’s AirPiano, but being the persnickety nerds we are, we think its more like a theremin than a piano. The device lets users play 24 different notes with a wave of the hand over the AirPiano. The “keys” are arranged in a matrix of three tiers with eight notes per tier; if the user sustains his or her hand over the AirPiano, the corresponding note is sustained.

It’s construction is relatively simple: an Arduino, several infrared sensors, and LEDs corresponding to the notes make up the device. It doesn’t have any built-in audio hardware at all, so it’s most basic use is as a MIDI controller. Still, it is essentially an unspecified input device, so it could theoretically be used for other purposes. For us, it’s fun to just watch the AirPiano in action.
