DIY trackball
I did something like that. Check out my repo https://github.com/Ocelot08/gojiball/

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?

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.
What are some alternatives?
When comparing gojiball and rp2040-pmw3360 you can also consider the following projects:
aball - A Ball - Buttonless trackball for all
ploopy-nano - A very small trackball-only mouse. Mechanical files, PCBs, and firmware all included.
pmw3360-breakout - Breakout board for PMW3360 optical mouse sensor
trackbowl-mk2 - The ball is the trackball
trackball - A trackball mouse. Mechanical files, PCBs, and firmware all included.
trackball_module - 34mm trackball module with ADNS-5050 sensor. This module can be implemented with existing DIY keyboards via wiring.
