    Self-rechargeable battery

    Thanks for your replys. We are experimenting with a small motor (toy motor) and it seems to be generating enough current (25-30 ma, 4.5V) to energize our led circuit. We looked at the bicycle dynamo as an option but it takes too much torque to turn. Now we are looking for a way to store and...

    Self-rechargeable battery

    I'm working on a project which involves a circuit board (leds)in a small enclosure (3"Hx3"Wx2"Deep). This would be mounted close to a mechanically driven shaft with variable rpm's(0 to 500 rpm). My question is if it's possible to mount a motor on this shaft to generate enough...
