Step 1:Get your parts!
OK, so the parts list is pretty basic.
- 1 Bike that you are willing to do some stuff to (every thing is reversible)
- 1 Small gear that will fit into your chain
- 1 Small piece of wood
- 1 Smallish DC motor
- 1 Cell phone
- 1 Cell phone charger that you are willing to destroy
- 1 Solder
- A crap load of duct tape
- Hot glue
- Assorted washers, nuts, and bolts
Tools:
- Soldering Iron
- Socket wrench
- Hot glue gun
- Coke and Dr. Pepper
- Good music to listen to
- A friend to help you out
Step 2:Mounting the Gear onto the motor
OK, now you need to mount your gear onto the motor. Our axle was little too small to fit into the gear, so we wrapped it in some duct tape. We then used a copious amount of hot glue and some washers to hold it in place.
Step 3:Mounting the Gear and Motor onto the bike
Gee, we sure are doing a lot of mounting today! OK, this part is easy, you just need to put the motor setup on the bike in a way that the chain will catch on the gear and spin the motor. Its easy to do this with some hot glue, zip ties, and duct tape.
Step 4:The Wires!
OK, now for the electronics, just cut the head off of your charger and strip the wires off of it, and then solder them to the motor. You may have to use some resistors depending on the voltage that your cell phone takes. You can also wrap the finished product in some colored tape to match the bike like we did!
Step 5:Connect the cell phone and ride off into the sunset!
OK! You are done! Just put your chain on the gear and ride off into the sunset! Thanks for reading!
