I've built a model wind turbine (1' radius) that is actually generating some (not much!) electricity. AFAICT, it makes 6-10VDC (depending on wind speed) and about 10mA (doesn't seem to depend on wind speed). Generator (alternator, I guess) is a stepper feeding into a couple of bridge rectifiers and caps. Right now, all it does is light a LED.
I'd like to have it charge a nicad battery and run a LED from that at night (like a solar garden light).
Is it making enough power to be worth adding a battery and some sort of charge controller? Or should I just be content with a "proof of concept".
TIA,
Chris
