The Enigma-E is an electronic analogue for the M3 and M4 Naval Enigma machines. It’s a remarkable project developed by Paul Reuvers and Marc Simons of Crypto Museum. For you money you get a beautifully constructed PCB, all the components and a superb manual that walks you through the construction process. Seriously, it’s been a long time since if had such pleasure following a long set of instructions. The kit comes as just the naked PCB and components but you can buy boxes as well (as I did) to give it that real Enigma feel. Power is via an external supply or 9V battery.
Construction took me a couple of weeks, here and there, and was reasonably straightforward, the only heart-stopping moment being the separation of the plugboard and main board (went well, phew). A few mods to the box later and I had my own Enigma machine, which I intend to use on tours around Bletchley Park. For an added bonus, the Enigma E comes with a simple RS232 interface. From this you can receive the stream of encyphered text from the Enigma-E. The final photo shows a successful hook-up to my MacBook. This gave me an idea but that’s another post. 🙂
I thought anyone considering buying one of these may like to see how construction goes, so here’s a photo library of the build.
