Mouse

it would be kind of neat to port this for an existing open-source mouse like [1] or [2]. 1: https://ploopy.co/mouse/ 2: https://github.com/biomurph/Mouse

I'm a trackball user, so thats what i tend to catch. the principles are pretty similar. Just turned over. https://www.youtube.com/watch?v=BEN1XgCNqqc

For the mouse example (specifically), you could solve that by making (say) an OSS mouse: https://github.com/biomurph/Mouse But creating your own case for it. It'd likely be fairly time consuming, and need lots of iterations. But once done, you'd be able to re-use the design pretty much forever. :)

I'm the hacker behind the Open Source Mouse Repo. I still have some ADNS2620 sensors in my stash (yes, that was a typo that is now fixed). Look into the readme and see that there is a company called PixArt that seems to be the only source for some of these parts. I did get a bite (mouse bite?) from their rep at the time of the OSHWA Summit 2 years ago, but they went crickets. This project could get resurrected if there is a replacement sensor chip. I kind of like the Arduino Leonardo + ADNS sensor, and not interested in just a breakout of an 'all in one' mouse sensor. If yer interested in getting a full kit or an ADNS sensor, please comment on the github issue tab https://github.com/biomurph/Mouse/issues/7
