Just wire your LEDs in pairs back to back with a series current limiter.
QuoteJust wire your LEDs in pairs back to back with a series current limiter. I think you mean to wire them anti-parallel. But LEDs will mostly fail at a reverse voltage above 5 V!Chuck, I hope the magnets are properly oriented, you can get them in (at least) two orientations.Nick
Hi Chuck, the magnets you are using and this is just a question. When you purchased the magnets, did they specify that the north and south poles were end to end or front to back? Don
We both know the reverse bias voltage on one diode of the pair can never exceed the forward bias voltage of the other.
I received my magnets from KJMagnetics and installed 8 of them on my armature. I've done a bit of testing and results are a bit disappointing, but I think I will be able to get it where I want it. I've installed 8 magnets and have 200 turns of #27 wire on one pole of the stator. Turning the armature at somewhere around 1500 RPM's and feeding the output through a full wave rectifier gives me .25 volts. Multiplied by 8 would give me 2 volts. That's probably enough to light an LED but if I add another 8 magnets, I'm thinking I'll get 4 volts and if I add 16 magnets I should get 6 volts. Since the #27 wire is rated at .287 amps, I'm guessing an incandescent lamp is out of the question.Chuck
