I built this after borrowing a Preonic and slowly reducing the keymap to a 34 key layout. Touch typing actually feels good on it compared to row staggered boards.
I’m looking now to what I will do next, I’m still stoked with it after four months usage. As an excuse to try more designs I will probably build a 34 key dactyl manuform for home.
It’s based on miryoku with some keys shuffled around, but basically home row mods and layer switches. Holding F and J enables symbol layers on the opposite hand, hold S for a numeric layer, hold D for navigation etc.
It does need some work for a handful of awkward cases, but the basic idea is solid and typing/programming works well.
