I Built an Arduino 7 Times Bigger (And It Actually Works!)
I built an Arduino Uno that's 7 times bigger than the original—and it's not just for show. This giant board is fully functional!
Inside is a real Arduino Nano, with every single pin on the outside connected to the real board inside. You can program it, upload code, and connect components just like a normal Arduino—except now everyone in the room can actually see what's happening.
In this video, I walk you through the entire build process:
Designing and 3D printing all the components at 7X scale
Creating a three-layer PCB structure to hide the wiring
Making functional giant pin headers, LEDs, and a reset button
Wiring 32 pins from the giant board to the real Arduino inside
Building giant LEDs and resistors to match the scale
Testing everything with real Arduino code
This project makes for an incredible teaching tool for classrooms, makerspaces, or anyone learning electronics. No more squinting at tiny components—this Arduino is visible from across the room!
