David Philip Barr's 34-key diodless split Demeter has been around for two years now, but it was missing from kbd.news.

It's an open-source low-profile Choc-spaced split keyboard – either wired or wireless.

Another 34 Key Keyboard with no diodes. […] There is a wired version for promicro type controllers and a bluetooth-first version for nice!nano type controllers – David Barr.

Thanks to yyoungs for bringing this project to my attention.

Specs

• 34 keys (5x3+2)
