I had 3 goals when making this keyboard.
I wanted a split keyboard, but I didn't want to have to relearn how to type.
The thumb clusters on the ergodox or the layout of the keyboardio would have a learning curve that would require some muscle memory and it would be frustrating if I had to work on a laptop or someone else's keyboard.
I wanted a keyboard that could be split and used individually. An Fn key on the thumb cluster could mirror the other half, so anyone with use of one hand could type relatively normally.
- I wanted to be able to find keycaps semi easily.
The full keyboard has 70 keys, and can be filled with 1u keys from a 104 key set caps.
The numpad/arrow/function keys of a full keycap set can be used on the thumb keys and modifiers of this keyboard.
I liked the overall design of the ergodox, but I didn't like the thumb cluster,
and I liked the keyboardio, but I didn't like the layout of the outer and inner most columns.
A normal keyboard is not symmetrical, so the layout on the keyboardio couldn't be standard.
For my specific layout I designed the layout on the outer most columns to be as close to a normal keyboard as I could
The left most column being esc, tab, Fn(to mimic the poker2 I was familiar with) shift and ctrl
The right most column being, backspace, ], enter, Fn(the firmware I used needed 2 Fn buttons, one for each half) and ctrl
I put the shift key to the left of the Fn key.
At this point, if all the thumb cluster was, was 8 spacebars, anyone could type on it normally with nearly 0 experience and nearly 0 learning curve.
The firmware I used was Soarer's Controller, A link can be found on this page.
I uploaded the 2 firmware files I used for my layout. splitkey-LEFT.sc and splitkey-RIGHT.sc
I recommend some rubber feet, the plastic alone will slide around on a desk.
Depending on the material used for printing, you may need to scale up the files slightly.
Some of my Gateron switches would fit in the slots, but would be so tight wouldn't reset.
Also I printed with clear abs, and it shows some signs of cracks around some of the switches.
