I find it interesting that there was a time when everyone seemed to get overboard with thumb keys and that now things seem to settle at two per hand.

Given the thumbs limited movement, I came to a conclusion that 2 keys are comfortably reachable, but to reach the third thumb key, the thumb needs to get into a weird and uncomfortable position. That was my problem with the corne I had and I just stopped using the innermost thumb key because of that. Do you have a similar experience?

Have you tried or were inspired by The Voyager? My friend has a Moonlander and we were discussing that the Voyager might be the ideal for the setup we were looking for. https://www.zsa.io/voyager

I haven't tried and wasn't aware of the Voyager at the time I started this project. Looking at it now, I think I would come to the same issue of the switches being too close to each other.

My first split was a corne (I have a feeling that many people started with a corne here) and then I wanted a draculad[0], but it wasn't available for almost a year. These two keyboards had given the most of the inspiration for the YetiS.

I'm currently designing a board from actual traces of my finger movements on paper (I was mildly amused when I found that they are not symmetrical, like all human features) in combination with these: https://fkcaps.com/keycaps/hex . It's also my first attempt at using a MCU directly (kinda, MDB50Q). Probably not possible to make a product from my anthropometrics, but I could try average out a few hands.

The human is not perfectly symmetrical by a vertical line - same as our faces!

Do you have the project somewhere online to share - git, blog, reddit, etc.? I would like to have a follow up on your progress!

Thanks for the interest, it's on the back burner at the moment because I'm currently rage-coding a text editor :). Here's the repo regardless https://codeberg.org/jcdickinson/hexkbd

MacBook keyboards have a similar modifier layout to a Space Cadet in some ways: On your left hand, there’s {Cmd, Opt, Ctrl, Fn} in a row. Emacs on MacOS can use all four modifiers, e.g. mapping them to the historical {Ctrl, Meta, Super, Hyper} keys that were in the same place on a Space Cadet.

That is why I have those for keys I rarely use, such as 'esc' and 'del'. Relatively rare - as they are obviously used frequently enough but not really when typing.

And then I hit them with my middle finger instead, or rather smash them as it requires the whole hand to move slightly.

So in my case does not affect speed or comfort (not a frequent VIM user etc)

But if I only had two thumb buttons I would be ok.

Interesting to me you say this, as my main criticism of most ergo / split keyboards is they don't have enough keys on the thumb. I started with a Maltron [1] with 8 keys on the thumb and that seems a good arrangement to me.

My Mitosis layout has 8-button thumb clusters but only three on each hand are used frequently as thumb keys. On the other hand, they're set up in my layout so two on each side can be held simultaneously for shift+num layer.

The rest I just use for miscellaneous other uses, like pgup/pgdn and inverted-T arrow keys. It's not for use with the thumb, but it's just a handy place to put keys you'd have to move your hand for anyway.

Interesting. Back in the '80s, the ergonomic keyboard [0] designed as part of the Japanese TRON project was originally supposed to be produced in three different key pitches for differently sized hands, based on measurements of Japanese people [1]. Another aspect was that some key columns were splayed, being more apart further away. It has inspired many follow-ups in the DIY ergo-mech scene in more recent years. [0]…

Years ago a chip supplier suggested using their RTOS. We asked what it was called. They nearly shouted, "Industrial standard Micro Industrial The Real-time Operating system Nucleus, haven't you heard of it?" This would begin a year of Google translation of Japanese RTOS docs.

Neat keyboard. Also pretty cool how far the TRON project went and how many parts of computing it influenced.
