An ErgoDox-ish but asymmetric split keyboard by valpackett: ErgoNICE.
KBD.news Published January 15, 2023
ErgoNICE is an open-source 69-key column-staggered split mechanical keyboard by Val Packett. With a rotary knob, extra connectors, a 3D printed case with "floating key" (borderless) design, and Rusty firmware.
I made a custom split mechanical keyboard! Because it's me, this involved things like contributing to a PCB design tool and discovering a ridiculously optimized way to read a keyboard matrix – Val.
Project files were published almost a year ago, but the author just shared a blog post about the design process.
Some highlights: SMDA left half and through-hole right side, DIP package I/O expander, designed in Horizon EDA (rather than KiCad), etc.
