There's nothing micro about this super-sized Arduino Uno

Arduino boards power everything from robots to RGB lights, but they're a little on the small side. YouTuber UncleStem has his own solution: build a gigantic, yet fully functional one.

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. 

"I wanted to hide the Arduino inside the board layers, and the Nano's profile is much slimmer than UNO's," UncleStem, who asked us to refer to him by his channel name, told us in an email.

As for the motivation behind the project, UncleStem explains it not only as a fun hobbyist challenge ...
