Hand Cranking

Project Number: 2

Description: Build the circuit shown by placing all the parts with a black 1 next to them on the clear base grid first. Then, assemble parts marked with a 2, and finally the parts with a 3. Be sure to place the parts with their (+) side oriented as shown. Place the wind fan on the motor (M4) shaft. Turn the handle on the hand crank (HC) in both directions to make things happen. Warning: The hand crank is sturdy but not indestructible. If you push hard on it or crank it really fast, you may break it.

Snappy: The hand crank uses magnetism to change the mechanical energy of the spinning shaft into electricity.
