Bike light generator
Ah, drats. I had hooked it up to a cheap dollar store circuit board with two LEDs. I spinned the axel with my finger and got near-full light. The motor was from a stereo system I took apart...I'm not sure what it was used for, but my guess is that it powered a mechanism that spun the interface open when the stereo was given power. I figured the bike would power more current than just my finger. I might try to experiment around with it until I find a more appropriate motor, but thanks for the confirmation!
I believe the motor you have is not a stepper motor, stepper motors have 4,5 or 6 wires, not 2. The DC motor will produce power, but not enough. The stepper motor I used will generate about 1 amp I think.
I have sourced a stepper motor but the calculated resistance is roughly 68 ohms with load. I'm very new to this thing, but my guess is that the resistance is way to high, correct?Here's the specs for the motor: http://www.nmbtc.com/motors/part-numbers/Brush-DC-12V/MXN13FB12F/4593
