Cheap optical mouse was pretty much useless. Logitech M705 seems to work ok with a white trackball, but doesn't like the red one. That was just balancing the ball on top the mouse by hand, so nothing very fast. I found some smaller 10mm OD bearings in my parts pile. I could definitely make a tighter package with the smaller bearings, but am afraid they wouldn't spin as freely and would wear out a lot faster. Not going to pursue the optical route for now, but I'm wondering if scuffing up a cueball and dunking it in dye would result in a good enough pattern for the mouse to see. --- Quote from: PL1 on July 09, 2023, 01:39:06 pm ---Between those two options, always choose Opti-Wiz. - The one input type that the KADE interfaces never handled well enough is spinner/trackball. They had really bad backspin, even with medium resolution encoder wheels. --- End quote --- Thanks for that. I was already making provisions for KADE as it fit on the side of the housing better. I will switch over to the Opti-Wiz. |
