I know this is mainly a keyboard related forum, but I am in need of a new mouse and would like something to go along with my ergo keyboards. I have known about the Ploopy for sometime which is an opensource trackball.
I am not a trackball user but I Iike that it is operated with the index and middle fingers instead of just the thumb also the Microsoft Traball Explorer which has a similar layout is getting great reviews despite being severly outdated. The Ploopy is also an opensource project and there are QMK builds available.
Having said all that there are a few downsides to the Ploopy. The bearings are apparentley quite loud, upgrading the firmware requieres an ISP progprmmer or similar, cases are 3d printed. But it looks cool, is opensource and has a design which could help combat RSI and carpel tunnel syndrom.
Any chanche of something like this becoming the next Kaleidoscope powered project?
