One of my favorite custom LEGO kits of all time is Chris McVeigh’s Mac, but German programmer Jannis Hermanns has gone one step farther by building a tiny Apple Macintosh classic case from LEGO around a Rasperry Pi Zero with an e-paper display and Wi-Fi running Docker.
Jannis says in his blog post that he designed the case in LEGO Digital Designer, ordered the bricks (upon which he performed some rather shocking customizations to fit the display), and inserted the electronics he’d programmed himself.
The whole thing — LEGO, e-paper display, Rasperry Pi, power supply, and Apple stickers — cost barely over $100, and Jannis provides detailed instructions on his website if you want to build your own.
