Bike Phone Charger
I thought of making this a while back then I saw the bike contest so I decided to finally make it. When you bike the wheel spins the motor which creates energy to charge a phone.
Supplies
Tape
Electrical tape
Motor with a wheel
Some wood scraps to position the motor
The inside of a phone car charger
Attach the Motor Wires to the Phone Charger
Make sure the ground (black) wire is touch the outside metal part and the power (red) wire is touching the small part in the middle.
