Now you can find a lot of compact laptops with screens up to 7 inches. But enthusiast Paul Klinger
"Son" Lenovo ThinkPad
During the creation of a ThinkTiny with 0.96-inchPaul's display was inspired by the Lenovo ThinkPad notebook design. Although this is not a fully-fledged computer, only the trackpad works in it, it can be used to play simple games like Snake, Tetris and Lunar Lander.
The device case is printed on a 3D printer, inIt has an integrated 128 × 64 OLED display, an ATtiny1614 microcontroller and a 300 mAh battery that can be charged via Micro USB. Despite the fact that the parts were already quite small, Klinger still made some changes to fit everything. For example, the OLED display board was too large, so I had to cut off the top.
On the GitHub page, step-by-step instructions for creating a laptop are even published, so anyone can assemble such a crumb.
