The portable, folding keyboard I designed named the btrfld (butterfold) after its older, non folding, sibling the btrfly.
The key matrices are huge pain to wire and solder. I really need to design some pcbs for it.
Its all open source, more pictures on the repo: https://github.com/SolidHal/btrfld
Heres its older sibling the btrfly.
I got into designing keyboards because of my minor wrist disability. One of my wrists can't turn flat, so typing on normal keyboards is quite painful.
After trying ergonomic keyboards like the ergodox, corne, etc, I decided I needed to design my own to match my needs.
These two are the most recent results of that. They are my favorite keyboard children.
