Build second ergo keyboard

Introduction

After six months of using the Tractyl ManuForm keyboard and identifying its shortcomings, I decided to build another one. This time, I wanted a wireless keyboard with a 5x3 layout. I chose the Corne V3 Wireless as the base and paired it with the Logitech Ergo M575 mouse.

Challenges with My Tractyl ManuForm

The Tractyl ManuForm had several drawbacks:

Features of My New Build

The new keyboard meets my primary requirements:

  1. Wireless connectivity
  2. 5x3 layout

I also made some adjustments based on my previous experience: - Removed the dedicated CMD and ALT keys. - Added a "home row" remap for the DF and JK keys with long presses.

Build Process

To simplify things, I purchased a kit from AliExpress that included everything needed except the switches. I reused some Cherry MX switches from my previous build.

After some quick research and printing the case, I ended up with a sleek, minimalist keyboard that exceeded my expectations. For the firmware, I chose ZMK. After using it for a while, I realized I didn't need dedicated CMD and ALT keys. Instead, I remapped the DF and JK keys to serve this purpose upon long presses.
