This DIY Enigma machine fits inside a pocket watch

The year is 1940. Through the use of arcane atomic technologies, the Axis have brought back modern technology from the year 2018. Their main prize? This amazing Enigma Pocket Watch. This tiny watch, created by a maker calling himself asciimation, uses an Arduino Pro Micro and a small OLED screen to recreate the Enigma machine in pure code.

Asciimation previously built an Enigma wristwatch and he is working on a 3D-printed Enigma machine. The Enigma was a seemingly unbreakable encoding machine used by the Germans during World War II and was about the size of a small briefcase. Stuffing all of the logic into a tiny watch case — of WWII vintage — is an amazing feat.

Luckily the aforementioned time travel device was never built and this wild little pocket watch never made it into enemy hands, but we can only imagine the havoc it would wreak if some Panzer captain somewhere had one of these on his belt. You can read all about the build on Asciimation’s site.
