The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

DIY trackball prototype
And yeah, that's an Arduino Micro and I wrote the software, but it's pretty trivial at the moment, it just uses this PMW3360 library to read the sensor and the HID library to act as a mouse.

- Another monroewilliams Trackball!

Now comes the hard part - getting used to it

A portable trackball I wanted (ZMK powered, some buttons, fixed ball)
A core module just consists of nice!nano and a pmw3360 breakout board by jfedor2 (https://github.com/jfedor2/pmw3360-breakout) which is shown in the last picture. (By the way, jfedor2 has a lot of cool custom trackballs based on RPI which provide lots of ideas.) I'm planning to use this module to apply in various setting, and this was the first prototype to replace my Ploopy Nano.

Split keeb users, what trackball do you use and why?
Outside of the Ploopy, if you haven't checked out u/Jfedor's stuff I highly recommend it. They created an open source rp2040-PMW3360 pcb specifically for creating new kinds of trackballs. I have bunch coming on the way now (It's a little pricier due to the smd components) and the parts to make trackball 7 when I get here. It's bigger (uses a standard billiard ball) but it seems closer to the direction I'd like. /u/azat-dev on here posted a modified Kyria using Jfedor's 3360 breakout but I don't think they can post the files because it uses modified closed source code.

Custom Trackball Design
Personally I'd use one of Adafruit's nRF52 Feather boards with an optical sensor breakout like this (this one happens to be mine, but you can find others).

UK/EU trackball sensor breakout boards?
Here's a nice one if you want to order your own from JLPCB: https://github.com/jfedor2/pmw3360-breakout

DIY trackball prototype
You're absolutely right and in that spirit I've posted the STLs here and the sensor breakout here.
What are some alternatives?
When comparing PMW3360 and pmw3360-breakout you can also consider the following projects:
