Very nice layout! My background too is in electronics. Is this your own circuit design or a reconfiguration/improvement on S&T Geo? Are you writing your own code? I built a custom Enigma based on S&T Geotronics instructables Open Enigma.

100% original design. Will look like an Open Enigma, but smaller, way smaller, uses 3.5mm audio patch cables for plugs. The project started by designing the plugboard and that determined the size of the main board. Here are the kind of things I design: hackaday.io/arduinoenigma |

hobbit601 I am curious about your machine, can you post pictures? It's always fun to see Enigma builds!

   Sure. Homemade PC boards, laser printed, transferred and etched. Nothing as elaborate as yours. It was actually my first attempt at making double sided home brew boards. Same circuitry as the S&T Geotronics Open Enigma/Instructables post. The top plate is a different configuration than the kit, in that it fits over the top of the PB key tops, so the entire assembly can be taken apart for service without having to remove the key tops. I had to add a filter capacitor and some decoupling caps to eliminate some noise and flicker on the 16 segment LEDs. Runs on a 9V battery. Added a protection diode in case of reverse polarity. The top plate and the Stekkerboard are both made from double sided copper clad board. The plug board is cosmetic. The Stekkerboard jumpers are routered hardwood, painted, with ground off nails as pins, and black shoe laces for the cloth covered cables. I also added cosmetic rotor thumb wheels adjacent to the 16 segment displays. All of the labels are home made. I yet have to built a wooden carry case. I am planning to build a second machine, full sized unit with working typewriter style keys, and working plug board as a summer project. I drew inspiration for this from a YouTube video of a "TEV" Enigma build, see www.youtube.com/watch?v=6VxZnlFm_iQ Check it out when you get a moment. |

That's a nice build! Do you have access to Ponoko? They can now cut 6mm plywood.
Here are some enigma builds. Check out the last one, it is very realistic, but has a 20 character limitation, maybe the stepping mechanism was not built.

alank2 here are some current pictures of the hardware. Electrically everything works. Work on the software continues. Going for full compatibility with Dan Palloks simulator except for the unlocked mode and maybe the maintenance wheels. http://instagr.am/p/B1cUf8SH923
