Relay question (adding relay to Oscars LED driver board) - it works!
<< < (2/10) > >>
Chris:
Isn't this really a job for a transistor?
Samstag:
You should probably be using a relay AND a transistor.  Driving a relay from the keyboard lights will probably destroy the LED driver circuitry eventually.

Sorry to butt in on this thread but is it possible to have a relay do a push button action (short 2 pins) for a second then go back to normal when 12v is applied?

Like say i turned on a 12v device can a relay short the power button pins on my pc for 1 or 2 seconds then stop shorting them while the 12v stays on?
ShinAce:
No, not without inventing some kind of RC charging circuit to cause a delay. You're on your own for this one. And please stop jacking threads.

I second the transistor idea. Have the transistor amplify the current from the LED, and then use that to drive a relay. My guess is that the lamp is 10 watts or over, in which case I would not drive it directly from the transistor. That should keep you out of trouble.
