An Enigma-E in the Museum at Bletchley Park

The Enigma-E is a modern electronic replica of the German key machine Enigma from World War II .

Layout and function

Completely assembled circuit board

The Enigma-E is a kit ( kit DIY ) delivered, for example, on the shop of the Museum of Bletchley Park or over the Crypto Museum is available, and except for the bare printed circuit board (PCB) components required all for assembly - with the exception of a Housing - contains. The kit is supplemented by an approximately 60-page manual which, in addition to a circuit diagram , explains the assembly and operation of the Enigma-E, provides historical background information and some real Enigma radio messages .

The electronic Enigma is significantly smaller (about 230 mm × 195 mm × 55 mm) than the mechanical original (340 mm × 280 mm × 150 mm) and contains light-emitting diode displays instead of the original light bulbs . The mechanically rotatable roller set is also being replaced by integrated circuits (ICs) and the typewriter keyboard by modern push-button switches . Functionally, however, it corresponds very closely to the model. It is able to emulate the Enigma-I used by the army and air force of the Wehrmacht as well as the two models of the Kriegsmarine , Enigma-M3 and Enigma-M4 .

UhrBox-E

As a supplement to the Enigma-E, the Enigma clock is available as a separate kit, called UhrBox-E . In addition to the bare printed circuit board (PCB), this kit also contains all components required for assembly - again with the exception of a housing.
