home made trackball on Instructables

Guy made a really cheap trackball out of an optical mouse on instructables.  Might be useful to someone who is on a budget.

Not a lot of detail on this one, but gives you the idea.

obviously the guy was making a trackball and not a keyboard...

it seems he doesn't need such thing as a keyboard...

As I recall, someone here made a 360 steering wheel using a similar technique.  They had a steering wheel on a shaft and inserted it in a hole in the front of the cab.  The shaft slipped over top of an inverted mouse (a ball mouse IIRC).  When the wheel was turned, it would register as left/right movement on the mouse.  I suppose an optical would work better for that.

Another way this could be done is by finding a ball mouse, decasing it, and using a larger ball in place of the small one that came with it (pool ball?).  It wouldn't be quite as nice as an arcade grade trackball, but it should work pretty well.
