lalboard VS adelheid

Good eye! W.r.t the key placement, I was actually inspired by the lalboard, which is an open source version of the DataHand.

Drawing inspiration from the vertical actuations of JesusFreke's lalboard, the keys above and below the home row are positioned such that actuating them involves the continuation of a single motion (i.e. extending or curling the fingers) rather than two separate motions (extending then pressing down or curling then pressing down, as is the case with a conventional flat keyboard layout). Less muscle memory + shorter travel distance = quicker and more comfortable typing!

It also incorporates some novel features: * Drawing inspiration from the vertical actuations of JesusFreke's lalboard, the keys above and below the home row are positioned such that actuating them involves the continuation of a single motion (i.e. extending or curling the fingers) rather than two separate motions (extending then pressing down or curling then pressing down, as is the case with a conventional flat keyboard layout). Less muscle memory + shorter travel distance = quicker and more comfortable typing! * I've yeeted keys that I find exceed a certain (low) threshold of difficulty to press on a standard ortholinear layout. These include the (QWERTY) n and b keys, as well as all the keys outwards from the pinky column. * To make up for this lack of keys, the left side of this keyboard features a powerful thumb cluster with five keys (four of which are vertically actuated: one by the base of the thumb (actuated by curling the thumb inwards), two by the tip of the thumb (actuated by extending the thumb upwards), and another by the thumb knuckle (actuated by moving the thumb outwards)) that allow for fast level-shifting. * The right side incorporates a trackball mount with a mechanism (consisting of a switch mounted underneath the trackball) that allows the trackball itself to act as a "switch" that can be pressed down to both enable mouse movement and activate the mouse button layer. This means that you don't have to press any buttons to enter the mouse layer before using the trackball -- the action of pressing down the trackball (and thus activating the trackswitch) shifts into the mouse layer. I refer to this collective assembly as the "trackswitch". * Both the trackswitch and trackball sensor have fully parameterized mounts with mounting mechanisms that allow their distance from the trackball to be micro-adjustable. * Fully parameterized case mounts for the arduino micro and pro-micro MCUs.

Maybe build something like https://github.com/JesusFreke/lalboard

Have you ever looked are https://github.com/JesusFreke/lalboard ? Adopting thumb clusters from there might work.

On the hardware side you could use switches like in the lalboard which is modeled after the DataHand. All keys use a pair of magnets to provide the clickiness and key return force, and an IR LED and phototransistor for detecting a keypress. It would be a large change on the hardware side but good to be aware of as an option as this design is reminiscent of those two keyboards.

Not quite TKL, but the Adelheid is an open source Alice with arrow cluster and F-Row

I've recently decided to create another fork of Pizza_on_Pineapple's Adelheid keyboard to widen the layout for a few extra keys.  The result is this 115% Adelheid XT prototype which can support up to a whopping 125 keys - perfect for displaying the maximum amount of fancy keycaps you just blew $300 on, plus some nice artisans as well!  I've never used a Blackpill controller before, so this project was the perfect excuse for me to get familiar with it.  Since I had so many pins to work with, I went ahead and added an encoded and OLED screen as well.

Design is not mine, found it here https://github.com/floookay/adelheid (thanks to floookay!).

Some time ago I got a Majbritt and for some reasons the PCB wasn't working. Since it's hard to get a new PCB I used the PCB as a switch and stabilizer holder and handwired the keyboard instead. Details: Keycaps: EnjoyPBT BoW Switches: Lubed and filmed Koalas Stabs: A mix of Durocks V1 and C³Equalz lubed with Krytox 204g0 and Tribosys 3205 Controller: Elite-C V4 Other: Wrist rest: Adelheid

Adelheid

There's this open source one https://github.com/floookay/adelheid

The Adelheid by floookay is an Arisu-fork with function keys (repo). Built by u/Ok_Promotion_6175.

Custom build pulled from the open source Adelheid, Big shoutout to the creator.

ever checked out an open source build such as the Arisu or the Adelheid? Heres one that I've built: lightss on or off

I saw this open source keyboard, the Adelheid, on github and had to build it. I ended up having plenty of extra parts and would like some money back. The boards cost about $30 each, and the acrylic case was around $150 to get made. The PCBs do not come with the mini USB port soldered on, but I will include it in the package. Acrylic case will also come with standoffs and screws needed. All boards are flashable with QMK toolbox right away, and the key-combo to set it into DFU mode is both shifts + b.
