My previous blog posts talked about diode-free keyboard designs using topology, and specifically using a partial Tutte-Coxeter graph for keyboards with 30~42 keys. As hinted at, I spent June making my own no-diode topology-based 36-key ergonomic keyboard PCB design using the Open Source tools Ergogen and KiCad. This is designed as an alternative PCB to fit the existing Gamma Omega keyboard's 3D printed case design (case design or modification can be a future project).
