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/

Details

Right now it's fully functional(I'm typing this on it right now), but I still need to add in the RGB LEDs as well as switch to the current version of QMK firmware instead of just relying on kbfirmware.com

The initial layout was designed on
- http://www.keyboard-layout-editor.com/
Then that layout was imported in to the plate and casing builder site and the svg of the keyplae was exported from there.
- http://builder.swillkb.com/
Then the svg was imported to freecad to create the plate and housing.
I then used @riskable's openscad "keycap playground" to make the keycaps.
- https://github.com/riskable/keycap_playground
and I used kbfirmware to define the keymap and generate the firmware(in attached files)
- https://kbfirmware.com

The next steps I need to wire up the neopixels for per/key rgb, and then setup my QMK build environment as there's some newer features that kbfirmware doesn't support.

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.
