Have an optical mouse? Tired of the humdrum regular red color emanating from the bottom? This is a super easy hack to change the color of your mouse!
Step 1: Parts Needed
A mouse (optical, not analog with a rubber ball in the bottom)
An LED, must be very bright, and of the water clear casing type. 5mm is the most likely size. So far I have tested green and blue LED's. Blue seems to work best, but green works varying on its brightness and the surface of the mouse pad. It tends to work better if it is brighter, and if the mouse pad is a lighter color (I had good results with a white sheet of paper)
Others have had luck with a variety of other types, such as IR leds, as the light emitted from these cannot be seen with the naked eyed, creating an "invisible" look. Others have used UV, but with varying results as UV usually reflects only off of white (or very light) surfaces. Strangely enough, some have had luck with UV on black mousepads :)
Desoldering braid, wick, or solder sucker
Soldering iron, with solder
Optional: Helping hands. Not needed, but very, very helpful.
Step 2: Take Apart Your Mouse
Step 3: Locate the LED
After you take the PCB out of your mouse, you need to find the LED. Most likely it is in some sort of plastic casing. When you find it, make note of the pads it is connected to.
Step 4: Desolder!
Step 5: Add LED's
There are a couple mistakes I made in the video. First of all, I didnt completely re-assemble my mouse. Oops! It works fine anyway. Second, I totally tried to force my cable in the wrong direction. Another oops! Fixed that and i was able to put it all together.
