A Modern But Classic Enigma Machine

Hacking has always brought more good to the world than not hacking. The successful efforts of the Allies during World War II in deciphering the Enigma machine output still reminds us of that. Today, the machine is a classic example of cryptography and bare-metal computing.

We have covered quite a few DIY Enigma machines in the past, yet 14 years old [Andy] really impressed us with his high school science fair project, a scratch built, retro-modern Enigma machine.

As close as you can get: Andy’s modern enigma machine (left) next to an original from the Worldwar II (right, image source)

With its wooden enclosure, keyboard, interchangeable rotors, and plugboard, his build resembles an original Worldwar II enigma machine down to the letter. However, when looking closer, you’ll find that the rotors are implemented as electronic modules that plug into D-Sub sockets on the machine. Also, there is a 16 segment display that displays the rotor position as well as an LCD screen that lets you comfortably read the plain- and ciphertext. On the inside, you’ll find an Arduino Mega along with 1,800 other parts and 500 wires, and of course, this modern version has a backspace key.

It took [Andy] over 9 months to put all this together, and he now finds himself among the winners of the State Science & Engineering Fair (SSEF), who will be sent to Intel as representatives of their states. Given his experience in field-capable computing, we’re sure [Andy] can help Intel reconquering mobile. Enjoy the video!

Thanks to [Arduino Enigma] for the tip!
