Marble Maze- part 2- Marble and Ballbearing Detector

The Marble and Ballbearing detector makes lights flash when a marble goes by on the track. I made it out of a small windchime, string, 26 AWG wire, copper plated steel wire, a screw, and some hot glue. Some of the wire is from an old printer cable. When any type of marble goes by on the track, the marble knocks the chime into the wire. The chime dings when the marble hits it, then the circuit is completed and LEDs blink. They don't stay on long because the chime quickly swings back.
