Creators! Feel free to tip me off about your keyboard related projects to bring them to 140K readers.
Evalyn Emmerich aka SolidHal shared the files of her Btrfld v2 (pronounced "butter-fold"). The originally handwired keyboard comes with a set of PCBs now.
Now with PCBs! No more awful hours of handwiring! – SolidusHal.
Featured in KBD#76, the Btrfld (v1) was the "foldable, portable sibling of the btrfly" – another handwired monoblock keyboard by the same author.
Despite the new PCBs, Evalyn still doesn't recommend the btrfld for a first build, especially because of the folding mechanism:
Getting the steel rods cut, ensuring the ribbon cables are the right length, and soldering the flipped smd diodes are some unique challenges that assembling something like a corne or dactyl variant doesn't have.
Features
- 5 key dactyl-manuform-mini thumb cluster
- flat, tented qwerty keys
- 6 extra mappable keys
- bluetooth (optional)
- folds flat for portability
