Happ Trackball Help
(1/1)
chrisindfw:
I am thinking of buying a used 3" Happ trackball from a friend. How do I connect this to my computer? Do I need an Optipac or something similar?
Thanks

Your best bet is an OptiPac. Easy installation (take the wires, connect them to the board with screw-down terminals, plug in, GO!.

Optipac, or a mouse hack.
Do a search on this. Even I, with remedial soldering skills, was able to pull it off in about 1.5 hrs.
$5 PS2 mouse
$3 solder and molex connector for the Shack.
I could probably do one now in 30 minutes.

True you can do it cheaper, but my personal opinion is, go for the optipac. You're buying a solution you KNOW works, and you now have an interface for a spinner, or even 2 spinners, and one more trackball if you wanted to.
Note: If you get an optipac, and you don't have an Ipac, get the Optipac USB version. It draws its power from the USB port Otherwise you have to get +5 and gnd to the optipac another way.

Just fyi for the original poster, you can get +5 & gnd off your computer's power supply.
