# smallwave

![PCB Preview](https://raw.githubusercontent.com/RosenNX6/smallwave/main/gallery/main-top.png)

The smallwave is a 34 key wireless split keyboard with a e-paper style display.
This design ultimately comes from the popular [Sweep](https://github.com/davidphilipbarr/Sweep) layout but was built by modifying the [Urchin](https://github.com/duckyb/uchin) design and inspired by many aspects of the [Flipper](https://github.com/benvallack/the-flipper) and Corne layout.

## Design Software
#### KiCad
PCB design, part locations, copper traces, and pads. This was a steep learning curve for me but the software was incredible once I got the hang of it.
#### AutoCAD
PCB shape (edge cuts). This can be done in KiCad but I am inexperienced with the software and felt much more comfortable drawing prototype shapes in a software I am more familiar with.
#### Inkscape
Used for making the PCB art through the use of SVG files. 
#### Github
Used for programming the keyboard in the ZMK language directly in the web browser. How cool is that? More on this below.

## Firmware
The smallwave utilizes the ZMK programming language. To view, download, or edit the zmk programming used for this project, visit the [zmk-config-smallwave repository](https://github.com/rosennx6/zmk-config-smallwave).

## Inspiration/Credits
This build was inspired by the Ferris Sweep, Ben Vallack's Flipper, and Duccio's Urchin. I started this project with zero knowledge of keyboards, PCBs, or programming but, along with browsing [r/ErgoMechKeyboards](https://www.reddit.com/r/ErgoMechKeyboards/) the videos below were very helpful for me in getting started.
