An Enigma cypher machine in a pocket watch, with Arduino and an OLED display!
Exciting to read in Hackaday about YouTuber asciimation building an Arduino-based Enigma code machine (vintage World War II). The Germans used large typewriter style machines to encode and decode messages for broadcast. The system was broken by the Allies through a great amount of work and money.
The amazing thing is it fitting inside a pocket watch form factor. How much would the Allies have wanted for one of these 75 years ago?
