(I used this information to create this model)

 

instructions:

  1. Thread an end of the copper wire into the bottom of the flashlight.

 

  1. Wind the wire over the spool, but every several layers add a layer of tape or paper so as to keep the stability between the layers

 

  1. After you finished winding it, solder a able to one end of the copper wire, so it can be plugged into a breadboard

 

  1. Place the magnet inside the tube, and use the caps to glue the tube shut. Make sure it is a strong seal.

 

  1. Build a circuit on the breadboard as seen in the photo.

 

  1. If you filled out everything correctly, after you shake the flashlight for 30 seconds and turn the circuit on with the switch, the LED will glow or several seconds.

 

Note: this circuit is designed to be on while you're shaking, and the capacitor is only there if fill in the spaces between the magnet passing through the coil.

 

Other note: if you have any questions or comments, please leave a comment and I will reply. also, pictures for the steps are bellow:
