| Run LED's off of +5V on Opti-wiz? |

Excellent. I have one panel which will only have two, so I figured that would probably work. But the other panel I intend to do 4 buttons (2 LED each) in this configuration. http://led.linear1.org/led.wiz?VS=5&VF=1.9&ID=20&N=8 My concern was that it would interfere with the Opti-wiz operation. Thanks for the info. |

My thoughts on this one are as long as you don't pull more current through the USB / PS/2 port than it it is able to deliver, you should be fine. With non-powered USB ports, this is up to 500 ma (before any devices are factored in.) So I don't see any problems with 2, 4 or 8 LED's being powered from the 5v line on the interface, unless you have an LED-Wiz on the same port with a bunch of LEDs being powered by it. As mentioned before, make sure you use the correct resistors for your LEDs or else LEDs = junk :) RandyT |
