HolyKeebs just announced their new keyboards with integrated trackpoints: holykeebs.com/pages/trackpoint . Something they do that is really cool is build them into the microcontroller itself, so if your board has the microcontroller in a convenient place, you can add the trackpoint straight to an existing device (already sell it for pimoroni trackballs, trackpoint in Q3). I have a Corne from him with the pimoroni, and I enjoy it, but the pimoroni is not a full mouse replacement for me.

I think the 2.4ghz is going to be the most rare feature. I found essentially one Etsy seller (https://www.ebay.com/sch/i.html?sid=vooooodooooo&_pgn=1&isRefine=true&_trksid=p2349624.m3561.l49496) and then the dygma. I think since Bluetooth in integrated in to microcontrollers, this becomes the simpler solution.

This is a nice clean layout! I appreciate that it isn’t trying to be tricky, but just lay everything out simply. The only part I’m not really getting is the equals sign relative to things like plus and times? Seems like typing equations, and things like += or *= kinda awkward? Beautiful all the same.

I notice all the 1.5u choc caps are out. I assume there is no way to make those for the giveaway?

Dactyl Manuform is always in style! Beautiful build!

So this one offers no prebuilt, but I forgot that the Ximi is dual trackball. Maybe you can get someone to build one? https://fingerpunch.xyz/product/ximi/

Not sure about your timeline, but the Naha Create is currently on Kickstarter, and I think might satisfy all these requirements: https://www.kickstarter.com/projects/naya-create/naya-create

In general, I’m not sure how easy it is to have multiple pointing devices? For the example you give of a coarse and fine pointing, the most common solution is to have keys that switch between coarse and fine pointing on a single trackball. I’m not sure if QMK can support two pointing devices at once (without significant customization).

For single pointing devices, I’d check https://bastardkb.com/ . They are also very slick devices, but can get pricy.

I have a pimoroni trackball that I use for a variety of things which might feel good on some knobs too. I think that text cursor will likely feel pretty good, particularly if your encoder ticks while twisting. Then you could make one tick equal one arrow key press, and you dial in precise cursor location.
