This repository contains the ZMK firmware configuration and STL files for my wireless Dactyl 5x6 keyboard build.
The STL files are generated using https://ryanis.cool/cosmos/. You can access my configuration using this link.
The keymap defined in ./config/dactyl_56.keymap is outdated since I have shifted to using zmk-studio to be able to change the mapping without re-flashing.
Sadly, zmk-studio does not provide a way to export your config to a file for reproducability. This means I will loose my keymap when I re-flash the firmware. This is not exactly true as explained in this issue comment, but I am not aware if it is possible to backup the on board keymap as of writing this.

You can visit the following links if you want to learn more about the build process.
- The original dactyl project. This is great to learn more about the design of the dactyl style of keyboards. I highly recommend watching the talk.
- Dactyl Manuform build stream on YouTube by Kevin Eckert. This is where I got the idea of using copper tape for connecting the columns of the keyboard. The video series features a wired build but most of it applies to the wireless variant as well.
- This Reddit Post. It shares a few tips for "Looping" the diodes and using a mini breadboard for soldering the microcontroller header pins which I adopted.
- Dactyl Manuform Repo. The readme contains wiring diagrams that helped me during the actual build process.
- ZMK Docs is pretty much the only resource I used to configure the firmware. The project is very well documented.
