Tri- color LED Mouse Makeover

Step 3 Install the TRI color LED with a 100 ohm resistor

This step may vary depending with the mod your are doing. I soldered a 100 OHM resistor inline with the + (the longer) lead on the 3 color led and since this is a USB mouse, connected the wires directly to the + and - connectors on the circuit board. I found that this peticular LED is sensitive to current requirments, to much resistance and all the colors won't light or cycle . Too little resistance an it will have a very short life !!. The measured voltage was aroung 5 vdc. Mount the LED in such a way that it will fit into the lens and give you the illumination effect you want.

I did something similar with one of those tri-colour LEDs from one of those solar LED garden lights with the plastic ornaments that look like butterflies, hummingbirds, or whatever else they have, and I am using it as a power indicator light on an old ATX power supply I'm planning on using to power a 70W total power amp I'm still working on (mostly the research and design stage right now) and I have it connected to the +5V PG (I think the colour of that wire is supposed to be grey, but the wires are old, and it's been in the light for quite some time, so it might supposed to be something other than grey, but that's what it looks to be now, anyways, it's the one where the motherboard tells the power supply that the voltage level is good) with a 330 +/- 5% ohm resistor on it, and it showed all colours no problem...then again, it was also designed to run from a solar-charged 600 mAh AA size NiCd battery...

also,wire the sw to green and any black
