So here’s my version of this mod, but in black with blue lights to coordinate with my rig and desk:
the iceweel mouse mod
This was a beige OEM Logitech optical mouse, I paid about $12 for it. The red LED was switched for a Blue Nichia with no loss of tracking. The additional LED lighting the wheel is a Nichia as well. The shell is vinyl dyed black. The extra LED is powered by +5V taken from a point right next to where the cable mates to the circuit board. I removed a small filter cap and installed my LED+resistor in its place.
here’s the best place to grab +5V inside this mouse
Note: the top pic is slightly photoshopped to compensate for the typical gamma of a PC monitor. On my monitor at home the original pic looks nice, but most monitor’s gamma is messed up, so I lightened the midtones in this pic a little bit.
