What is it?

This is an electronic replica of the Enigma crypto machine used during WWII by the Germans to encrypt all the military communications. It is intended to be as close to the real one as economically possible.

Why did you make it?

To have a real enigma cost way to much and a simulator on the computer just isn't the same. Here is an electronic version that is the same size, works the same (messages encrypted/decrypted on meinEnigma can be exchanged with real enigmas and simulator software) but for a fraction of the price.

What makes it special?

It does exist a few electronic replicas but what stands out with meinEnigma is:

• Same size as original, a original lampfilm works on meinEnigma size-wise
• Has real rotors that works close to the way the real enigma rotors works
• To configure it you turn the rotors, not pressing some buttons
• Does morse code
• Does TTS (text to speech, say the letters out loud)
• Real plugboard that works like the original
• Serial interface that can be used to configure it and encrypt/decrypt messages
• Based on standard off the shelf components like arduino nano and rotary encoders. The only custom parts are the PCB boards, the rotors and some parts that holds it all together.
• When not in use it has a built in clock so it can be setup to show the time
• Done with modding in mind
• All sourcecode available on github
• Schematics included

NOTE: This is a kit that need to be soldered together. It is the hybrid version and that means it contains 3 SMD (surface mount) components that need to be soldered on, the rest is all through hole. It comes with documentation on how to assemble it and how to use it. More info about the kit can be found here
