The Effiddy by Simon Schödler is a 50-key, column-staggered, wireless split keyboard. Inspired by the Totem, it features an additional row and less aggressive splay. Designed for Choc-spacing and 1350 Choc v1 or v2 switches.
Having had a stash of keyboard components sitting around in my office, I decided to have another go at a custom keyboard and follow up on my previous post about the shoedler54 with another wireless split, which is also solely designed declared in ergogen.xyz – Simon.
The design and name are inspired by the Kindlifresserbrunnen (Child-Eater Fountain) in Bern, Switzerland: an unsettling effigy (a physical representation of an idea or belief, often ritualistic or iconic in nature) that embodies folklore, symbolism, and cultural memory.
