I'm currently working on a scratch built trackball setup to fit my narrow and shallow CP. Been wondering if I'm wasting my time with encoders vs just using an optical mouse. This makes me question even more.
The trackball could be resting on 3 bearings with an optical mouse underneath instead of fiddling with rollers and PITA to mount industrial encoders from the parts bin.
Here's my mouse hack spinner from way back.
The knob is a caster wheel with a cabinet door pull pushed into the center.
It had a really good feel. The wheel had some weight to it.
