Mod Help
« on: May 28, 2004, 02:46:14 PM »

I have a nifty little mod idea but I've run into a snag.  Without revealing the details or anything, I was hoping I could get some help.  

Basicly, I want a relay (I assume thats what it is) to act as switch when an LED lights.  On whent he LED is on, off when the LED is off.  Now, the only multimeter I have is older than I am and dead, so no info on the LED.  It's a 5mm and probably around 2-3.5 volts. As for the resistance, no clue.

Here's what I need to know:
A: What kind of relay (or whatever) do I need?
B: Will such unit be able to be used as a power switch for a computer(I'm sure it'l work, just wanna make sure there is no risk of crisping up my mobo)?
C: What would I need to make sure that the relay is a only on for a maximun of 2 seconds even if the LED is on?

A. 12V relay. You'll also need an optoisolator or a transistor to drive the relay.
B. Yes, but you can use an optoisolator instead.
C. Make a 555 circuit.
