Nitipak Samsen’s coin-flipping machines

This video shows nine different coin-flipping machines designed and built by Nitipak Samsen of the Design Interactions program at the Royal College of Art. His aim is to build a machine that can predictably flip a coin to land either heads up or tails up.

It’s not easy to control the fate of a flipped coin. Samsen has identified 31 factors that influence the outcome, but believes it is possible to nail them down.

I’m impressed by the wide variety of prototypes he built, as well as his stick-to-it-iveness.
