meinEnigma – electronic enigma replica

The meinEnigma is an electronic enigma replica DIY kit aimed at being as close to the original as economically possible.

The short version is that it is a kit with PCB and parts for sale starting at $300USD (see the shop for details). This will give you a kit that after being assembled is an electronic enigma replica that has the size and function close to the real enigma but without a box to put it in.
The kit comes with almost everything needed, only thing missing is things like soldering tools, screwdriver and pliers.
All documentation comes in paper and electronic format (=no download from internet required), and the firmware is already installed.
The documentation describes step by step with pictures how to assemble the parts.

Highlights of the functions:

  • Full emulation of several enigma models like M3(army,Air force), M4(Submarine), more are planned like Norway(post war), Swiss and so on.
  • Physical size and position of rotors, lamps, keys and plugboard within a few millimeters of original (=as far as information can be found)
  • Ring setting, stepping, double stepping (including the exception when starting at a notch), plugboard all implemented as original.
  • Sound effects from original enigma
  • Possible to save up to 14 user configuration plus current config saved whenever turned off
  • Emergency reset-to-factory-defaults red button – to wipe your settings when someone try to peek on it.
  • Configurable by physically move around things (rotate wheels, connect cables) as well as over usb (serial) port.
  • Can encrypt/decrypt from physical keyboard as well as serial port.
  • Encrypted/decrypted character shown on lampboard and serial port.
  • Can send encrypted code in morsecode
  • Designed for modding, several small features that makes it easy to put it in a real case and do other modifications to it.
  • Kit includes schematics
  • Source code for the firmware is licensed under GPL3 and available on github
  • When not used it can be set to show time
  • More to come
