In an Explo workshop last year, we attached the audio output of a radio (I
think) to a small motor. Then
we attached a stick to the motor. The stick vibrated. Bite on the vibrating
stick and our mouths turned into speakers. I am using 1.5 V motors and I
need advice on what to use for my audio output. The signal
from my CD player is too weak to power the motor.
Thanks, Jeff Friedman
