With a MIDI device, Maayan Migdal has built a set of real-life air drums. Migdal cut the rake part off of a few garden rakes for the drum sticks, and added accelerometers and USB ports to each. The left stick takes care of the hi-hat, while the right stick has two separate modules that cover the snare and crash cymbals. From there, he went on to fix up some sandal-esque foot pedals, sticking a pair of sensors into his flip-flops — the left, an accelerometer to pick up the bass drum, and the right, a light sensor to pull in the hi-hat pedal.
