Based on nezumi's Amber PCB and konomu's one-handed layout, key-yack put some real effort into designing an ergo board and keymap for single-handed usage.
I started with layout similar to the 3x5+3 Amber keyboard I've been using. When early prototyping with Zebra, I found that the same layout was not as comfortable in low profile without tenting and some tweaks had to be done. Namely, I moved the thumb block a bit closer to the main block and to the side. Key spacing is MX horizontally (19mm), and minimum Choc spacing vertically (17mm). I tried the minimum choc spacing in both directions initially but found it very error prone; I was hitting the neighboring keys all the time – key-yack.
No github repo as of writing this but some ideas, tips and train of thought in the original post.
