Ich bin der Musikant mit Taschenrechner in der Hand
... Und wenn ich diese Taste drück
Spielt er ein kleines Musikstück
Not so long ago, a creative guy hacked his slippers and some hand rakes or similar robust hand tools to build a light footed air drum kit with Arduino.
His initial project, part of a technology course, a three piece drum kit with four sounds, three accelerometers, a light sensor and USB ports, was later recreated and somehow improved by other makers.
Here comes the original demo with Killing In The Name (Rage Against The Machine). Sony Music Entertainement does not want you to enjoy the demo on this site, you'll have to watch it on YouTube.
