and lacks even a number row, relying heavily upon the fn key. There is
no PCB in this design, requiring [[http://deskthority.net/workshop-f7/brownfox-step-by-step-t6050.html][a manual matrix wiring approach]].

as daunting as it could be. It also allows for quicker iteration on
design changes since alterations only require cutting a new case.
