Title: IPAC LED volts?
Post by: chrisindfw on May 31, 2005, 03:37:56 pm

Say you plug in the led harness... Cut the ends off. How many volts are coming out of the led wires?

QUestion, is it enough to power a 5v light?

5V - doubtful, I think the limit was a few milliAmps.

Any idea how I can turn on and off a 5v light via the computer... Or even using the ipac...

You can use GameCab's LED driver board. There are also plans/schematics out there for you to build your own. GameCab's board is only $13.

So I can create the oscar LED driver board.

Plug the IPAC inputs (num,scroll,caps)

Power it with 5v from ipac.

and when the computer turns on the caps lock, the caps LED will light?


The good thing is that this project has educated me so much on electronics, woodworking, and overall electronics :)

I believe so.

Yes for the Caps LED.  If You are wanting to power a 5V lamp from it, it might work, but I would recommend powering the OSCAR or Gamecab board directly from the PC power supply  rather than from the I-PAC.

You might be able to do it the original way, but I would double-check the loads and current requirements of the lamp before I wired it up.
