Title: power for LED's???
Post by: REBIRTH on December 06, 2002, 01:44:01 am

I'm sure a simple question - I'm just not seeing it.  I have an IPAC (no LED harness) and Opti-Pac.  I have a translucent trackball for which I want to hook up a couple of LED's to illuminate.  They apparently need a 5V source, which I know the IPAC/OptiPAC uses as power as well... Using them, or something else, where can I get a constant 5V source to light the two LED's?

Thanks!!!!!!!!

Your computer power source has +5V (red wire), just make sure you have a resistor before the LED.  This has been discussed a few times http://www.arcadecontrols.org/yabbse/index.php?board=1;action=display;threadid=663;start=0 (http://www.arcadecontrols.org/yabbse/index.php?board=1;action=display;threadid=663;start=0)

Perfect, thanks!  I did search before I posted, but obviously I didn't search too well.

Thanks again! :o

You might try picking up one of the led clusters available here.  Should provide tons of light and come with an adapter for attaching to computer 12v power supply:

The Opti-pac has terminals labeled 5v and ground.
I just used these and added a current limiting resistor
it works great and illuminated the trackball perfectly.
