![]() ![]() Their project is instead modeled on the original Enigma M4 cipher machine, and aside from a bit of artistic license, we think they nailed the visual style. They drew their inspiration from a hilarious build we saw a few years ago that hacked a children’s toy into an Enigma machine. This open-source Enigma replica by the folks at is simply stunning. Of course if you build one and start wearing it into the office we won’t judge.įiled under: Arduino Hacks, clock hacks, wearable hacks They learn about ciphers, embedded programming, and mechanical design and crafting (this is a hand-sewn leather wristband). This seems perfect for kids that are proving to have an interest in engineering. We’re pretty impressed by the functionality of interface considering it’s hardware simplicity. But that’s hardly avoidable when you’re not committing to a full keyboard. ![]() Quite a bit of button presses are used to set up each of the three encoder wheels. ![]() The device is demonstrated after the break. The user interface consists of an OLED display at 128×64 resolution, three buttons, with a charging port to the right and on/off switch on the left. We’ve seen Arduino Enigma Machines in the past so it’s not surprising to see it again here. With the speckled gray/black case and the Enigma badge branding has done a fine job of mimicking the original feel.ĭriving the machine is an Arduino Pro Mini. This Enigma Machine wristwatch is not only functional, but the appearance is modelled after that of the original machine. The Enigma machine is of course the cipher process used by the Germans during World War II. This one sets a definition for usefulness. ![]() We don’t find smartwatches to be supremely usable yet. It is also worth mentioning that should your travels ever take you to Buckinghamshire you can visit the Bletchley Park Museum and neighboring National Museum of Computing, to get the Enigma and Colossus story from the source. One was built into a wristwatch, another into a hacked child’s toy, but the closest in aim to ’s offering is this rather attractive replica also driven by an Arduino. We’ve featured a few Enigma machines on Hackaday over the years. The machine as it stands is a fully working prototype, the plan is that a final machine will resemble the original as closely as possible.Īll the code used in the project can be found on GitHub, along with ’s Arduino library for the Holtek HT16K33 keyboard/display chip used to handle those tasks. It supports all the different variations of rotors from the original in software, has a physical plugboard, and a serial port over USB through which all machine functions can be controlled. ’s meinEnigma is an electronic Enigma driven by an Arduino Nano, with rotary encoders to represent the Enigma rotors and multi-segment alphanumeric displays standing in for the lighted letters in the original. This has not stopped our community building Enigma replicas, and the latest one to come to our attention here at Hackaday shows some promise. If you want to handle one you will have to either have an outrageous amount of money, work for a museum, or maybe for the GCHQ archivist. Our grandparents’ generation saw to that through the chaos and bombing of the fight across Europe. Sadly for the Enigma enthusiast though, real machines are now few and far between. Without it we would not have had Colossus, the first programmable digital electronic computer, and subsequent technological developments might have taken a slower pace towards what we take for granted today. The World War II German Enigma encoding machine is something of an icon in engineering circles not just for its mechanical ingenuity but for the work of the wartime staff at Bletchley Park in decoding its messages. ![]()
