Mitosis Anaphase, a handwired sandwich design based on the Mitosis keyboard.
https://www.reddit.com/r/MechanicalKeyboards/comments/8wip5j...
I type with the keyboard on my lap so a split design didn't work for me, hence creating this handwired contraption.
I use the Dvorak layout and have two alternate layers. In the number layer, the top row is punctuation, home row is numbers, and bottom row spilling into the thumb cluster is F keys). The other utility layer has mouse keys and media control.
Keyswitches: Box Navy
Caps: Polycarbonate DCS alphas R1-R3-R4, DSA R3 for the tall thumb caps, G20 for the low thumb caps.

From the project README
An excerpt from the repository, fetched Nov 12, 2026.
Read the project’s introduction
Quantum Mechanical Keyboard Firmware
This is a keyboard firmware based on the tmk_keyboard firmware with some useful features for Atmel AVR and ARM controllers, and more specifically, the OLKB product line, the ErgoDox EZ keyboard, and the Clueboard product line.
Documentation
See the official documentation on docs.qmk.fm
The docs are powered by VitePress. They are also viewable offline; see Previewing the Documentation for more details.
You can request changes by making a fork and opening a pull request.
Supported Keyboards
Planck
Preonic
ErgoDox EZ
Clueboard
Cluepad
Atreus
The project also includes community support for lots of other keyboards.
Maintainers
QMK is developed and maintained by Jack Humbert of OLKB with contributions from the community, and of course, Hasu. The OLKB product firmwares are maintained by Jack Humbert, the Ergodox EZ by ZSA Technology Labs, the Clueboard by Zach White, and the Atreus by Phil Hagelberg.
Official Website
qmk.fm is the official website of QMK, where you can find links to this page, the documentation, and the keyboards supported by QMK.

56 sourcesThey use special "upper" and "lower" layer keys to switch between mappings. There's a whole open source ecosystem around a project called QMK firmware, and convergent common keymaps for keyboards that use it.

In I Like Small Keyboards> the OS is inconsistent/unclear about what scan codes are required to do things.
Both that, and there's an internal list that allows only Apple's (plus a few makers' like Logitech and Keychron) keyboard to _send_ the modifier keycode. Others are simply ignored. Sorry enthusiasts, Apple don't want to favor you.
https://github.com/qmk/qmk_firmware/issues/2179
In I don't know Apple's endgame for the Fn/Globe key–or if Apple doesI had a beautiful vision when programming my keyboard. The style at the time was to write a massive array in C with the keycodes for the various layers. I put commented out box drawing characters between the lines to delineate where the keys are. I wanted to use the C Preprocessor to #define the thin vertical box drawing character as a comma, but somehow that was out of the range of acceptable characters. If I had that, then my source would be 1% more readable to me, the only person who's ever going to use it.
https://github.com/qmk/qmk_firmware/compare/master...perkee:...
I still use tons of box drawing characters in comments. I'm actually writing a little doodad to let me edit them fluidly then copy them into my block comments, because a truth table is easy to read!
Your comment also reminds me of the introduction of type parameters/gen

https://wiki.ai03.com/ is what a lot of people use. Though it's probably easier nowadays to use an RP2040-based ProMicro form factor daughterboard so you only need to handle key placement.

Disclaimer: I'm a QMK Maintainer.
In SofleKeyboard – A split keyboard based on Lily58, Crkbd and Helix keyboardsI do wonder how much of that can be accounted directly to the RP2040. Projects like QMK[0] have been using a technically quite similar codebase for making DIY keyboards for quite a while now.
At first glance I'm not really seeing anything in GP2040 which couldn't have been done with any other somewhat-modern MCU. The RP2040 has undoubtedly been the catalyst leading to GP2040's widespread adoption, but it seems the same could've happened with a Pro Micro instead.

In I like the RP2040You should try to use OSL instead of MO (or TT) as the layer key action: https://github.com/qmk/qmk_firmware/blob/master/docs/one_sho...
In 00Key a 75% KeyboardI only use keyboards running QMK or ZMK, so:
My Caps Lock key is a Control/Escape key (when tapped it behave like a Escape, when hold it's Control), and my left Control is a one shot layer switch key [1], which means I tap LCtrl once, and then press Caps Lock + 5 to get Ctrl+F5. Doable with single hand and more ergonomic as I have an unusually small hand.
[1] https://github.com/qmk/qmk_firmware/blob/master/docs/one_sho...
In 00Key a 75% KeyboardI agree that reduced finger movement is a crucial step in achieving typing efficiency. This is nicely solved by mod tap modifiers in QMK/ZMK[1] where key acts as a char when tapped and as a layer while pressed.

2 points · Open discussionQMK, one of the keyboard configuration tools referenced by the article, has the "quick tap term" feature that handles this:
> When the user holds a key after tapping it, the tapping function is repeated by default, rather than activating the hold function. This allows keeping the ability to auto-repeat the tapping function of a dual-role key.
ref. https://github.com/qmk/qmk_firmware/blob/master/docs/tap_hol...
I use both space and backspace (in the caps lock position) as dual-function keys and find it very usable when I occasionally want to repeat-tap them.

In QMK and KeyboardsThe downside to ZMK is no copyleft protection. So when you buy a keyboard that advertises "ZMK", you're getting a binary blob you can't customize or audit.
OTOH, QMK has successfully forced-open proprietary keyboards that were sold with QMK forks and then repeatedly, emmphatically refused to release the source. This includes the awesome non-Bluetooth 1000hz-rate Nordic Semiconductor wireless feature of the NuPhy Air keyboards!
https://github.com/qmk/qmk_firmware/pull/21949#issuecomment-...
Copyleft works. In spite of all its haters.
In QMK and KeyboardsQMK is getting easier with its data-driven configuration. I think everything needed for Keybird69 is just json.
But if you like Python, there’s KMK http://kmkfw.io/ which I expect would run very nicely on the RP2040-Tiny in Keybird69. The Pimoroni Keybow 2040 that I used to use was programmed with CircuitPython (Adafruit’s MicroPython fork) until I reflashed it with QMK https://github.com/qmk/qmk_firmware/pull/21481
In I Made a KeyboardThey’re just keys - you can remap the middle ones to be your enter, tab, backspace and escape. That’s basically what I do with my Planck layout. https://github.com/qmk/qmk_firmware/tree/master/keyboards/pl...
