<< Hey, if you hook those blue leds up, what voltage do those need???
I hooked mine to the regular connector where the small ones used to be on, but that doesn't seem to have enough voltage.. the lights don't light up constantly (not a HDD connector) but flicker... go on and off... >>
If I remember correctly, typically, w/ 5V supllied to LED, use a 220ohm to 1Kohm resistor. Depending on how bright you want it. Some LEDs cannot handle that much current. Some can handle more. Just gotta read the specs and run the calculations.
Am I right? Its been a while since I worked with LEDs.
