(ongoing work …)
The main idea is to host a Raspberry Pi 4, a real mechanical keyboard and a small screen into a cheap rugged pelicase clone. Powered by a simple USB PowerBank. As I don’t have 3D Printer, for now I’m using cardboard to organise the screen and the Raspberry Pi 4. The Screen and the Pi are connected together using a ribbon and 2 HDMI connectors (to take less space than a cable). For now I’m using the Royal Kludge Rk61 Keyboard : Bluetooth and USB with RGB backlighting.
On this photo I added some adfruit feather boards and the KeyBow, and all is powered by an USB PowerBank.
