I wonder if there would be some way to attatch the potentiometer to a mouse in place of the mouse wheel/optical sensors on a mouse. It's still a mouse hack of sorts, but you wouldn't have to take the potentiometer out.

: : : If you describe the spinners a little better, I could probably help you come up with something.

: : It's simple really. Just a spinner knob connected to a 10k ohms potentiometer. The pot has two leads coming off of it. And it's a free spinning pot; no stops.

: : : If the spinner is just mounted directly to a potentiometer, then it wouldn't work to just attach it to a mouse wheel.

: : This is why I'm looking to build some sort of a circuit, rather than attempt to attach it to a mouse.

: : : You would definitely need to gear down the spin in order to get it to act like a real spinner (I could give you sizez of gears, etc, if you need them.)

: : : The way I look at it, your best bet is to try attaching the spinner to a horizontal mouse wheel inside a mouse (Tear a cheap one apart) and mount the board in a way that the wheel can still go through the sensors.
: : : If this ends up being acceptable, let me know, but my gut tells me that a direct spin on that mouse wheel would make it move too fast (Unless you have a mouse that have drivers which allow you to turn down the sensitivity).

: : Hmmm... if I don't come up with something, I guess I have no choice but to try this. I wanted to avoid having to remove the pot and try something a bit different than a mouse hack. Oh well........
