Rock trigger sequencer
 
attach a shaft to motor and a wheel to the other end of the shaft (think of an amusement park carosel). Attach rocks to strings and hang them from edge of wheel, evenly spaced. Turn on motor and now the rocks are in motion. Fasten a mic (cheap and crappy) to a small plastic flap. Place the flap where the rocks just nick it as they spin. Now connect the mic to some simple trigger generating circuit. Now you have a very primitive trigger sequencer. You can create different rythms if you tie some rocks so they don't hit the flap.
