Making a custom trackball's easier than I expected! In great part thanks to the folks making arduino libraries for the parts, of course!
Still not 100% sure on a final design, but the electronics work!
Ball's on BTU bearings for no stiction, sensor's a PMW3389, and going with an analog axis for the scroll wheel which works surprisingly well after tuning a pressure curve.
