Description

I've always wanted to make my own mechanical keyboard, so decided to take on the idea. I was inspired by the gherkin 30% keyboard. https://www.40percent.club/2016/11/gherkin.html and all the other great designs over at https://www.reddit.com/r/olkb/

DIY 3D printable 40% ortholinear keyboard.

Originally made using kbfirmware.com, but has since been ported over to full QMK, and now with VIAL GUI Configurator support.

I mostly made this just to see if a could since I had all the parts on hand. Next I'd like to make a split tented keyboard similar to the orthodex, but with the Cirque capacitive trackpads added.

But for now I'm happy with this design.

Firmware, Freecad project, and stl's attached.

Initial layout generated in http://www.keyboard-layout-editor.com
Data from KLE used to generate plate svg in https://kbplate.ai03.com and imported to FreeCAD.
Plate and housing made in FreeCAD.
Used the QMK Source/Environment to generate a new QMK firmware
Then used that to port it to VIAL to work with the VIAL GUI Configurator.
- Extract attached zipfile just goes in the VIAL keyboard folder in their source to generate new firmware or use as an example for your own.

Firmware ported to VIAL branch of QMK
Ticktok • 07/27/2024 at 02:50 • 0 comments

Ported firmware to VIAL branch of QMK, which has a GUI configurator.
Had to first port it to actual QMK source since I originally had just used kbfirmware which is no longer maintained. Then port that to VIAL.
Here's a screenshot of the configurator.
internals and the current key layers.

just wanted to make post including some of the pictures as well as the current key layout.

Here's the wiring.

This is the pro micro and wiring as well as the hardware reset switch I wired in.

and then screenshots from kbfirmware.com of the current state of the key layers.
