Bay Bus help

[Kulchenko]

Someone can tell me one links to a home made baybus?

And if someone understand about resistors what resistor should i use to pass 220v to a 2v led?

www.fanbus.com has alot of info on the baybuses.

Are you passing 220V straight to the LED, or is the psu toning it down to 12V? That'd be a lot of resistance for 220V

My fan is 220v volts not 12v... thats the problem. I don´t know what resistor to use

I just want to make sure, but are you powering it with 220 volts? But anyways the formula for resistance on the led is

(source voltage - forward voltage) / amps to run led

so

(220 - 2 ) / .02 (common amp for leds) = 10900

Correct me anyone if I am wrong
