Converting a Happ trackball to USB

Using a $0.99 generic USB mouse (model ms009s-blk)

This page shows the process I used to connect a 3" Happ trackball to a PC via USB. This would work with other optical arcade controls such as other trackballs, wheels, spinners, etc.

Please note that this will likely damage your computer and/or trackball optic board(s) if you do this wrong. I AM NOT RESPONSIBLE FOR ANY DAMAGES OR LOSSES IF YOU DECIDE TO FOLLOW THESE STEPS.
