The puzzle box project was based on my idea of a mysterious cyphered cube that by solving the codes on each side the box the top lid finally opens. The prototype was a working one. We used a small motor and a battery, led lights and Arduino to make it work. We used specially laser-cut plywood and metal. It is a combination of mechanical and digital decyphering. The team was composed of 2 engineers, a designer and a project coordinator. Thanks to my teammates Franz Lazerte and Mihael Plut for making this a successful project, and the whole Fab Lab team Igor Asonov and others.
