Closest split PCB based design with a Kinesis Advantage thumb cluster, I know of, is the Ergodox Would need tenting to emulate the keywells. Lovingly design and print a case with tenting legs for it? 🤔

I built a second ErgoDox to keep at the office. This is my first set of MT3 caps and I LOVE them.
Should be in here somewhere: https://github.com/Ergodox-io/ErgoDox

Keyboard Latency
> Is ZSA's build known to have latency issues compared to QMK?
ZSA is using a patched QMK - they even let you download the exact source for each firmware build they make for you. At the time when I switched to vanilla QMK (that was already some years ago), ZSA were veeery far behind master; running the latest QMK release fixed a couple of issues for me (like hotplugging the halves), so I guess there could be other improvements? No idea really.
> Would a faster microprocessor help
In the MCU world, latency and clock speed can have a very linear relationship - until they suddenly don't. The microcontroller's job is very simple really: scan the key matrix at a certain frequency, perform key debouncing, compare the current state with the previous, and craft a USB HID packet with key press/release events.
So having twice the clock speed could theoretically let you scan twice as often, so it might let you cut the latency in half. Except we have those pesky physics getting in our way! For simplicity let's assume we don't have split halves (where there's an extra serial connection slowing things down); I'm no EE so I only grasp these concepts at the surface level, but signals take time to propagate, and long traces on the PCB (and cables too) have a tiny bit of their own capacitance. (Capacitors are like really fast, really tiny batteries - but they still take a tiny amount of time to charge and discharge, which does all sorts of interesting things to high-frequency signals.)
On top of that, the electrical connection that the pieces of metal are making inside the switch, are never perfect at the exact instant the switch is supposed to (de)register: a couple electrons might start jumping over the air even before contact is made, and the physical connection is subject to normal wear, amplifying the "edge case" effect over its lifetime - which all together means we have to actually spend a certain amount of time "looking" at the state of the switch, to let it settle and make sure we got it right.
We end up spending so much time letting physics do its job that in a trivial firmware, the MCU is actually spending a significant amount of time... just sleeping. Which means we were later able to cram all sorts of madness like individual RGB lightning or status displays, and never decreased the poll rate.
Where would these 40ms come from then? Well I wouldn't get near the problem without an oscilloscope, and unfortunately I don't have one.
> I'm just starting to get into custom keyboards.
Then I recommend studying the original ErgoDox firmware & build instructions! It's extremely straightforward compared to a beast like QMK, which actually uses a whole RTOS.

Hotkeys in ergodox?
Hi! Does anyone here have some experience playing age on an ergodox? I usually move the right part out of the way so that I can have more space for the mouse (it is actually great for things like FPS because the mouse hand is in a very natural position), but the default hotkeys force me to move my left hand across both sides, making it hard to actually hit the key without looking. I've been only using control groups 1-5 due to this, which is less than optimal.

Broke my 4th MS Sculpt in 6 years, so I finally made the switch to mechanical.
The closest open source keyboard you'll get next to the Moonlander is probably the ErgoDox that it's heavily inspired from.

Keeping with keywells, there's the split kinesis advantage boards: - Without palm rest: Dactyl CC - With palm rest: Ergo S-1

Best DIYable KA360-like board?
I need a split keyboard with concave key wells that also has an ergonomic palm/wrist rest like Kinesis Advantage boards have. I borrowed a friend's Kinesis Advantage 2 for a mont last year and it was fantastic - much more comfortable for me than the handful of dactyl and dactyl-manuform variants I've tried (although I wished I could have slightly adjusted the spacing between the two sides). I'm not very able to pay to try a KA360 or Glove80 at the moment, but I have a well-tuned 3D printer and a drawer of various key switches. I know that critical aspects of Kinesis' form factor are patented, but I'm wondering if anyone has suggestions for DIY boards that feel a bit more similar to the real thing. Extra points for boards with 36-ish keys (more keys is fine, too, though). Trackballs are nice, too, but not required - either way, I'll probably add a TrackPoint on the right side. I've had my eye on the Charybdis Nano, but I'm not convinced I'll actually find it comfortable. If anyone has used both the Charybdis and the Kinesis Advantage, subjective comparisons are appreciated. I'm also curious about what the Dactyl-CC, and if people who've tried it feel it lives up to it's description of being more Kinesis-like. Thanks!

Layout review: Roast my choices
I'm building a keyboard inspired by the dactyl-cc (and by the Kinesis Advantage 360 by proxy). Before I started out laying up stuff, I've been thinking on the general layout. All feedback is welcome!

Looking for an QMK compatible Ergo close to the Kinesis advantage II
Not sure it qualifies as easy to build, but if you are willing to jump in a bit the Dactyl-cc is designed to feel just like the KA2. That's my current daily driver. It's a 3d printed body, so you'll have to order prints and do some hand wiring. If that's more than you want to sign up for it's probably not a good fit, but I've really enjoyed it.
