I have already dabbled somewhat in mechanical keyboards. My first DIY build was a handwired split ortholinear. I am currently deciding whether to build another split keyboard or make something a little more portable. In the mean time I have been gather parts and mocking up designs.
I managed to salvage around 90 switches from an old mechanical keyboard
After using an ortholinear for some time I am convinced to keep using ergonomic layouts.
This wonderfully designed 3d printed split on thingiverse with an awesome star wars vibe to it.

I do miss having a numpad and after using layers don't really miss function keys so these are the two main designs for now.
