Creators! Feel free to tip me off about your keyboard related projects to bring them to 120K readers.

This split cyberdeck was designed and shared by legion.ultimedia.

A dual screen Cyberdeck with split keyboard that is foldable for ease of transport – legion.ultimedia.

The screens are 13.3" 2560x1440, the system is a UDOO Bolt (Ryzen 1605b, 8GB RAM, 256GB NVMe SSD) and the power supply is a USB-C PD enabled power bank (20V@3A out wtih 26Ah capacity).

The system can be charged over USB-C PD as well while running.

With regards to the keyboard, two Pi Picos (one for each half) read the key matrices. Both are connected to each other via serial UART and one is connected to USB.

Switches are Gateron blues and the keyboard "cases" are filled with some silicone to soften the sound of the keys.

The trackball is an old PS2 optical mouse where the author soldered the buttons and wheel on the opposite side of the PCB; using a steel ball suspended over the optical sensor as the trackball. The Arduino on board the UDOO Bolt reads it using the PS2 protocol.
