Rae-dux by andrewjrae
The rae-dux is a 36-key (diodeless!), wireless keyboard inspired by the Architeuthis Dux. This project used to use the samoklava workflow, however the auto-router had troubles with the splay, currently I just use the image generating parts of the samoklava workflow.

Piantor by beekeeb
The keyboard name Piantor (Pi-antor) is the portmanteau of "Pico" and "Cantor". As the name suggested, it has the same strong column stagger layout as the Cantor Keyboard created by u/diepala and is powered by Rasyberry Pi Pico or other compatible RP2040 boards (e.g. WeAct RP2040).
Features
* RP2040 MCU: Low cost yet powerful microcontroller. You can enable a lot of features and layers without worrying about the firmware size limit. Rasyberry Pi Pico is reliable and easy to source too.
* Breakable pinky column: Easily convert the PCB from a 42-key to 36-key layout
* Hotswap (Kailh Choc v1 Hotswap Sockets) or soldered-in low profile choc switches: Experiment with different key switches with the hotswap sockets, or solder the key switches for a more stable build.
* Cantor layout - Ergonomic strong column staggering for short pinkies.
* Diodeless - A more robust build with fewer things to solder or break.

Avalanche by vlkv
The Avalanche keyboard is an ergonomic split keyboard with 4x6 (or 3x6 if you break off the 'digits' row) column staggered keys, 5 thumb keys, 1 additional key for the pinky (break off-able too) and 2 additional keys for the index finger (64 keys total).

Draculad by MangoIV
QMK-powered 34-36 key split keyboard
Features
* 36 keys, two of them can be replaced by rotary encoders making it support 34-36 keys and 2-4 encoders.

* One SSD1306 OLED per side
* Support for the pimoroni trackball
powered by QMK-firmware (Firmware has been merged and can be found on the QMK master)
* Aggressive pinky stagger similar to the Kyria but with a slightly alternative thumb cluster to raise comfort for large hands
* Support for MX and Kailh choc v1 switches
* Files for fr4 plate and acrylic bottom plate as well as OLED window

Nijuni by krikun98
The Nijuni (formerly known as the RT-22) is a 44-key split keyboard inspired by the Jian (stagger, pinky and controller footprint) and the Jorne (thumb cluster and wiring).
It was originally conceived by DwarZ, however, V0.1 had a screw placement issue that restricted it to Kailh BOX-style switches. V0.2 is trouble-free, and prototypes have already been tested.
Features
* Wireless focus - battery footprint, power switches and no LEDs in sight
* Uses Jorne firmware - so QMK and ZMK support
* MX or Alps soldered or MX hotswap support in a single reversible PCB
* 6 column version also available for 100x150 PCB promos.

giraffe36 by sboysel
A 36 key split keyboard with "long-necked" thumb clusters. Wired, powered by Raspberry Pi Picos, diodeless. Inspirations include Ferris Sweep / sweep36, draculad, samoklava, piantor.
Goals
* Simplicity
* Declarative design (ergogen and specifically, my fork)
* 5x3+3 wired split
* Soldered MX to build plateless
* Diodeless
* Lowered thumb cluster comfortable to my hands
* To learn PCB design!

Ferricy by icyphox
Ferricy is a slightly modified version of the Ferris Sweep, sporting a more industrial look with sharper edges.
Features
* Ferricy MX based on the Sweep MX Bling.
* Ferricy Choc based on the Sweep Half-Swept.
* Tenting puck support has been removed (I have no use for it).
* Squared-off edges (plates modified accordingly).
* Larger holes in the PCB for M2 standoffs to pass through.
* The stupid Rust crab is gone.
