Prelude This is my Cosmos Dactyl Split Keyboard. There are many like it, but this one is mine. My keyboard is my best friend. It is my life. I must master it as I must master my life. My keyboard, without me, is useless. Without my keyboard, I am useless. Introduction This is a build log of sorts which runs through details of building a hand-wired Cosmos Split Keyboard. I don’t go through every detail but try and cover some tips and things of note.
