![]() ![]() ![]() This had the side effect that a letter would never encrypt to itself, a property exploited by the people who broke the enigma code. The reflector was its principal weakness, it made encrypting and decrypting easy, for the same wheel position, if A was encrypted to G, pressing G decrypted it back to A. The lamp stayed lit for as long as the key was pressed, once the key was released, pressing the same key again would move the rotors and another lamp would light. This current is sent back through the rotors by a reflector and then it lights up a lamp in the lamp field representing the encrypted letter. The main parts are the keyboard, which moves the rotors, then applies a current through the rotors. The enigma machine was an electro-mechanical encryption device used around World War II. It can even be powered away from a computer by using a 9V battery and a barrel jack plug. ![]() Sure, a phone app is more practical, but this is a physical device can be interacted with, taken places, shown around and be a conversation piece. Once the touch screen shield has been mated to the arduino, it sort of resembles the actual machine. Wouldn't it be something to have an Enigma simulator running in an arduino with a touchscreen. VIRTUAL ENIGMA SIMULATOR ANDROIDI found an excellent Enigma simulator for the Android platform and this got me thinking. ![]()
