![]() ![]() ![]() ![]() I used a Tamiya 70145 narrow tire because it was what I had. 1/2" Aluminum Angle Stock - Both Home Depot and Lowes have this usually in the hardware section or order it from McMaster-Carr #88805K41, You'll need a piece roughly 6in long Small nuts and bolts - I used the screws from the printer and some other hardware I had, #10-32 machine screws and bolts would be good Small rubber wheel - This attaches to the stepper motor and rubs against the wheel as it spins. Mechanical: 1x Bike Reflector bracket - I took this off my bike when I put the lights on. Here's what they are: Electronics: 1x Stepper Motor - I got mine from a printer I got at goodwill for $3 8x Diodes - I used 1N914/4148 from Radio Shack #276-1122, the personal powerPlant used 1N4001, Radio Shack #276-1101 1x Adjustable Voltage Regulator - LM317T, Radio Shack #276-1778 1x Project Box w/PC Board - Radio Shack #270-283 2x Resistors - Radio Shack #271-003 You'll need the 150 Ohm and the 220 Ohm 1x Heatsink - Radio Shack #276-1363 1x Battery Connector - Radio Shack #23-445 18-20 gage solid wire Electrical tape You don't have to get everything from the Shack but I find its easier and roughly the same cost as say Jameco or Digi-Key once you pay shipping. Your going to need a few things if you want to build a bike generator. Thanks to instrutables member a schematic of the circuit is also available. By adding the generator I can power the lights while riding. I got this bike for its simplicity, single speed means I can just hop on and go, but replacing batteries gets expensive and complicates things to much. While this is respectable it still requires some attention. My lights are both 3V, two AA's in the head light and 2 AAA's in the tail light, and the box said the head light will work for 4 hours and the tail light for 20 hours in blinking mode. There are many instructables on bike lights too. This is the light I got, Planet Bike 1200, but there are many options for bike lights. I got the idea and a lot of the info for this project from another great instructable personal powerPlant I recently bought a bike to commute to work and around town and figured for safety's sake I'd get a light set. BikeGen can also be used to recharge you cell phone or Ipod I made this friction drive bike generator to power my head light and tail light. Check out my new instructable BikeGen for the new generator which recharges 2 AA batteries and powers the lights. The is my first attempt at a bike generator and I have made many improvements to the project. ![]()
