Project #679
Machine Gun
Paperclip Vibrator
Use the circuit from project #677, remove the connection between points
A & B and make a connection between points B & C (using a spacer on
point B). The sound and vibration are different now. Compare the
vibration height and frequency to project #677. Now remove the connection between points B & C and make a
connection between points D & E. The sound and vibration are different
now. Compare the vibration height and frequency to projects #677 and
#678.
