Title: Finger + plus thumb control wired trackball?
Post by: 0100010 on Thu, 01 November 2012, 20:16:24

Does anyone make a decent wired trackball that can be used with both fingers and thumb control (ala Trackman Marble FX), but that also has a scrollwheel?

This sounds fancy. I want one.

I'm thinking about buying an arcade trackball and re-mounting it so that the sides and top of the ball are finger accessible.  The only part that may be a little difficult is a scroll wheel - but if I use the control board from a 2 button mouse with a scroll wheel, and just wire the opto-mechanical outputs from the trackball to to the mouse control board and re-mount the scroll wheel to my liking; may end up with something useable.

Although in the back of my mind I still think I should just buy a current trackball like the Slimblade and just live with it....

I think that someone on here has modded a scrollwheel onto the marble.

Well, just ordered a PS2 trackball, which is a poor mans version of an arcade trackball (HAPP or Betson/Imperial).  It was only $15 bucks and the internal design seemed fairly conducive to be modified into what I'm wanting.
