Enigma machines are fascinating devices, especially for young Makers looking to explore the world of electronics. Awhile back we featured a similar project from Italy, and we’re once again amazed by the work of 14-year-old Andy Eggebraaten, who built a retro-modern gadget of his own. The project, which was for his high school’s science fair, took nine months to complete.

These electro-mechanical rotor cipher machines were developed  in the early 20th century to protect commercial, diplomatic and military communication, used especially by German military intelligence during World War II.

In the video below, Andy opens the machine to show its inner workings: the unit runs on Arduino Mega along with 1,800 other parts and 500 color-coded wires. We can see that he evolved the rotors into electronic modules that plug into D-Sub sockets, and the interface is made using a 16-segment display showing the rotor position as well as an LCD screen to read the plain- and the encoded text.

Arduino was conceived as an open source microcontroller for artists, designers, and others who aren't necessarily techie/programmer types. Of course, all sorts of makers have flocked to this technology because of its versatility. But in spite of its relative ease of use, there's still a barrier to entry for new users. Like kids. For that reason, BirdBrain Technologies' Hummingbird looks promising. They call it "pre-Arduino."
