Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Is it possible to make a trackball with a 1000 Hz polling rate?
Not sure what issue you're referring to. Making a 1000Hz trackball? Yes, of course it's possible. I've made several. Any decent sensor (e.g. PMW3360) and microcontroller will do.
-
Any plans for a symmetrical trackball?
One example: https://github.com/jfedor2/rp2040-pmw3360

Tips for diy trackball?
It might be helpful to use jfedor's PMW3360 + RP2040 PCB - it has a Raspberry Pi RP2040 chip on it as well as a PMW3360 mouse sensor. Then they also designed some smaller PCBs for mouse switches.

Maybe I was wrong about the thumb positions
Quite a lot of work seems to have been done to allow PixArt PMW3360 (or similar) .. https://github.com/jfedor2/rp2040-pmw3360 … https://www.printables.com/model/131450-trackball-15

Don’t Talk To Me Or My Son Ever Again
Guy on the right is a Trackball 7 by u/jfedor. I had the RP2040+PMW3360 pcbs printed out and added Kailh GM 8.0 switches in there. The billiard ball is an Amarith Black cue ball (not an 8-Ball) I got off of ebay. Due to a parts shortage it's actually missing a few SMD parts that I'm having a hard time tracking down.

Custom Trackball Design
It's worth asking /u/jfedor if he has used the nice!nano in his builds. I know his dual-trackball build uses a Raspberry Pi Pico.

I have successfully crossed BB-8 with a pokeball
I've been into spheres lately and I've made this trackball. It doesn't sit on a desk, you have to hold it in your hand. It only has one button, but it totally works. The ball is 57.2mm and it sits on 2.5mm zirconium oxide bearing balls. 3D models, electronics and code.

Another DIY trackball
If anyone's curious I put the 3D models here and the files for the PCB and code are on GitHub.

Moonlander + Ploopy Nano : anyone else out there?
I did a similar thing with the aball. My extremely barebones version of it was small enough to fit between the thumb cluster and palm rest, so I was able to keep my right thumb keys and not lose any stability. I used that setup for a few months until I eventually built myself a Charybdis Nano.
- Can someone please explain to me how to understand and find these capacitors?

My last project of the year
Qmk trackball based on aball project, but with left and right mouse buttons and 3d printed case.

What is the ideal trackball for an ergo split keyboard?
Brickbots' aball also would look nice to a Lily58, specially if you try to make the cases match.
-
Can anyone help?
Yeah, I’m making myself one of these at the moment, all trackball with no frills, which I would have suggested but no buttons. Where are you based? Do you have someone who could help you build something like either of these? I’m in the UK in London and could happily make some of the parts for you but if you have someone local they might be able to make whatever modifications would make it work best for you.

Build a trackball
Along the same line there's also the aball.

Does anyone else stagger the right side angle so you can have your mouse closer?
I use the aball. I built the most minimal implementation of it possible: https://imgur.com/a/HiJgRkw

Kyria + KAT Cyberspace + Ploopy Nano
That makes sense. Would it be any easier to try to convert something like an aball that uses a pro micro style controller? Could you just drop in a nice!nano?
-
Where do I start!!!!!!
If you find a good split without a pointing device and you have q 3D-printer, the aball is for you.
