From the project
Home to my custom keyboard project "Yggdrasil"
This is the home of my first keyboard project that I dubbed Yggdrasil.
It's a 36% split keyboard that is tailored to be comfortable to my hand span. You can find the build guide here.
Here's what it looks like (minus plates)
And with 3d printed plates (and custom cables also done by me hehe :) )
