"In a video published last month on his fledgling YouTube channel, UncleStem built what he described as a seven-times-bigger-than-the-original Arduino Uno - though it seems larger than 7x - out of 3D printed parts, three layers of plywood to mimic the PCB and hide his wiring work, and, instead of an Arduino Uno, an Arduino Nano secreted inside to do the actual computing work."
"a fun hobbyist challenge (who wouldn't want to have a fully functional giant Arduino to play with?), but also as a teaching tool, rather than a way to address one's failing eyesight from too much squinting at microcontrollers. "If you've ever tried teaching Arduino to a class, you know the struggle. Everyone's hunched over these tiny boards, trying to see where the pins are," the video voiceover explains. "With this? No problem. Hold it up, point to the pins, and boom - everyone gets it.""
A maker constructed a massively scaled Arduino Uno replica using 3D-printed components and three plywood layers that mimic a PCB and conceal wiring. An Arduino Nano is hidden inside to provide the actual computing functions while preserving a slimmer profile. Exterior components like the ATmega chip, resistors, capacitors, and power adapter are 3D-printed for appearance, while interactive elements remain functional: LEDs, a working reset button, and operational GPIO pins. LEDs sit in clear 3D-printed enclosures and the reset uses a large housing for a smaller switch. The build serves both as a hobbyist challenge and a visual teaching tool.
