Where's ground?

[mahuti]

I'm sure one of you guys can help. Forgive me for being dense, but I've searched and I can't find the answer. Take a look at the attached picture. I ripped this piece off of the spinwheel in my mouse and want to wire it to my optipac.

One question. Where do I wire the ground?

[SirPeale]

Show a picture of the PCB, and likely we can show you your ground.

If not, you can attach ground to the ground wire coming off the mouse cable.

[mahuti]

What you see is what you get. I want to wire this directly into an optipac.

That piece. Not the whole mouse board.

[SirPeale]

I don't believe you can.  You need more than just the optic sensor to talk to the machine.

Someone prove me wrong.

[mahuti]

You don't need anything else. It works just like any of the other optic sensors.

[SirPoonga]

Ground is usually obvious because everything connects to it and usually uses a black wire.

What you will need, for a tball Iam assuming, witht he optipac is get tball optics (from bob roberts is the best place) and wire teh 4 wires to the optipac.
