Sound Activated Toy : This circuit makes a flower bop to the beat of music. The flower stem contains a crooked wire which
is spun by the motor. The circuit is a microphone driven peak-detecting one-shot and works very well. The microphone is in a sponge mount to insulate it from the vibration of the running
motor. Similar circuits are used to drive rock'n coke cans (added 6/06)
