C. Dux is a 38-key split wireless keyboard inspired by rae-dux and Architeuthis Dux (A. Dux).
Note: I did not consider designing a case as I use the keyboard with nacked PCB. So it's better to use leadless PCB and solder. I find SAC305 solder (with 380-degree solder iron) is a little harder to use compared to Tin-Lead 63/37 solder (with 280-degree solder iron), but not too much.
The keyboard layout and PCB is generated using Ergogen v4. Traces are added manually in KiCAD 8. I learned how to use Ergogen form FlatFootFox's Let's Design A Keyboard With Ergogen v4 series articles, highly recommended!
Refer to my zmk-config repo. I do local build, github workflow is not tested.
Some combos are inspired by Glove80 TailorKey. (I own one Moergo's Glove80. It's a great keyboard. I started using home-row mod with Glove80.)
Here's v2.0 PCB gerbers file. You can download the file and place order from JLC. I made a few fixes for problems found after I got the PCB from JLC, so it's not exactly the same file I've used but should work without problems.
For non-key footprints (power/reset switches, etc.), my workflow is:
As I suffer from RSI, I choose the 20g pink Choc v1 switches (which is the lightest switches I know). For keycaps, I find the 3D printed saddle variant of KLP-Lame-Keycaps quite pleasant to use. The keycap curve makes it easy to press the up & down rows, and helps a lot to position fingers on the home row.
I got the idea of mouting keyboard on desk and let hands go twards the ground from Ben Vallack's video The Perfect TENTING SOLUTION For Split Keyboards. Check out Ben Vallack's channel if you are interested in ergonomic keyboards.
This is the most comfortable way for me to use a keyboard. This position helps a lot to relieve my RSI and I can work all day long without much pain in my forearm.
This is my first attempt to build a keyboard. The rotary encoder is difficult to reach which is the biggest mistake I made.
The keycap used in this version is Chosfox's CFX keycap. (Search for "哈狐 Chosfox" on Taobao if you live in China.) This keycap is not as smootch as Moergo's MCC keycap, but it's still quite good and is much cheaper. But as I like the curved keywell of Glove80, I switched to KLP Lame keycaps later.
I'm quite comfortable with C. Dux v2 and I'm not planning to build an improved version soon. But I do plan to build a third keyboard for backup.
Here are a few things that I'd like to change:
