A must-have accessory for all the Cumberbitches in your life:
A three rotor Enigma machine I built. Being inspired after visiting Bletchley Park I decided to learn how the Bombe machine works and code my own version. First though I needed to fully understand Enigma. The best way to understand something is to build it so I made my own Enigma machine and housed it in a wrist watch. This is how it works.
