A three rotor Enigma machine wrist watch
This is one of the most satisfying projects I have done I think. Mainly because this is a real device and something so historically important. It is a fully functioning Enigma machine you can wear on your wrist. This is a three rotor Enigma machine as used by German Wermacht in WW2 for encoding messages.Way cooler than any Android Wrist or iPhone Mini watch.
