Secondary Electrical Makings

Age: 13 – 18 Years

Task

Embark on an electrifying mission to transform a 3D puzzle into a brilliant illuminated model! On competition day, participants receive a kit with all materials, including LEDs, wires, switches, a soldering iron, batteries, and a circuit board.

The challenge: construct a working circuit that lights up your model — creatively, neatly, and efficiently — within the given time.
