LEGO Computer Brick Functional OLED 3D Printing
Some of you may have this LEGO computer brick, but programmer James Brown wanted to make a functional version. So, he started out by 3D-printing the case before cramming an ARM-based microcontroller in there. The latter is what shows the screen animations and what appears to be lines of terminal code.

Despite how small the screen is, about half an inch across, it still has OLED technology. You won’t find a Raspberry Pi controlling everything, just a custom PCB that was printed specially for this project using a different ARM-based chip. Put simply, it’s designed to plug into a LEGO platform powered by a 9V battery. What you can use a Raspberry Pi computer board for is building a LimaTek Diskmaster floppy disk VCR.
