When [daniely101] wished a cut up keyboard, he determined to construct his personal. It wound up costing $25 to create a wi-fi board with no customized PCB required. Every half has its personal microcontroller, and the entire thing connects through Bluetooth. Whereas we don’t thoughts making a PCB, we are able to respect that you could possibly change your thoughts simply with this wiring scheme.
The 3D printed case holds the keys, after which it’s only a matter of rigorously soldering the keys to the microcontrollers. After all, all sides additionally has to have its personal battery. The ZMK firmware is cut up in half, one half for all sides of the keyboard. The nRF52840 CPUs have loads of wi-fi connectivity. The keys are set in rows and columns, so the quantity of soldering again to the controller is manageable.
Whereas we applaud the wi-fi design, it does appear odd that you must cost each halves and switch them on and off individually. However that’s the good factor a couple of design like this — you could possibly modify the design to not have a cut up. Or, you could possibly enable one versatile wire pair to run throughout for energy. After all, you could possibly modify the format, together with including or deleting keys.
You may contemplate including a pointing gadget. At the very least you don’t have to drag out a noticed.
