Happ Trackball mouse hack help

Thanks man! I actually already have that page bookmarked lol. They do help! I also read you can supply the 5v/ground using a Y splitter. I have a multi meter around somewhere.  Some guides mentioned removing  opto-transistors and IR emitter. Is this really necessary? Or is it just for saving power?

pbj:

You remove them to expose solder points and eliminate interference.

Hunk_4TH:

I gotcha. About to give it a quick test.

Hunk_4TH:

No luck with 5v/ground via the Y splitter. Gonna have to find out where it is on the mouse board I guess.

severdhed:

on my mouse hacks, i've never pulled power or ground from the mouse..i've always just taken it directly from the pc power supply (red and black wires) and it has worked well.
