Create and print dynamic mazes using a Raspberry Pi and a thermal printer

Mattias Jahnke (aka YouTube’s Engineerish) has built this lovely project from a thermal printer and a Raspberry Pi. Enclosed in a hand-modified box (gotta love a bit of Dremelling!), the Pi creates mazes using a technique known as recursive backtracking and then sends them to the printer for printing. A button controls when this all happens and, I think you’ll agree, the results are terrific for keeping young-ish ones entertained! 🙂 The source code is available here and you can view Mattias’ video below.
