This time I decided to build it just with the stuff I have laying around (luckily, I have a lot of stuff laying around :)).
Device is based on the Raspberry Pi Zero W Soc. It contains one main 3.5" SPI TFT screen and additional 1" OLED screen. Additionally, it has BT keyboard, pi camera and MLX90640 thermal camera. The casing is 3D printed on Prusa Mini. It has a motor and a linkage system which enables it to (semi) automatically switch between just the display mode and full terminal (display+keyboard) mode.
