"Gizmos: Enigma-E Electronic Enigma Machine," review by William Jacobs. Discover, May 2004.

The original World War Two code-breaking Enigma machines had replaceable rotating wheels that encoders and decoders reconfigured to create and decipher messages. Some of the vintage machines are on display at Bletchley Park in England. Dutch electrical engineers Marc Simons and Paul Reuvers have designed a digital, electronic version that can be purchased and assembled. Jacobs briefly describes the product and informs readers where it can be purchased.
