These new devices let you create music by waving your hands in the air. The sensor sticks can detect the position and velocity of your hands as they move in front of them.
Airheads work as a standard MIDI controller, you can connect them to most synthesizers or even a drum machine, so you can play some serious air drums. (Assuming you don’t mind gesticulating wildly when you’re playing your tunes.)
Each Airheads controller uses an array of LEDs paired up with infrared sensors to work its auditory magic.Flickr Video
A starter kit (soldering and assembly required), including a single Airheads controller and all necessary parts and cables is available from MakerSHED for $99.95 (USD). You can check out more videos of Airheads in action over on Flickr.
