Bletchley Park, the "home of the codebreakers" -- where Alan Turing and co cracked the Nazi Enigma machine -- sells "Pocket Enigma Machines" made from a clever cardboard disc inserted into a CD jewel case. It comes with a very good booklet explaining the basics of ciphering and deciphering with Enigma, and with a bunch of fun Enigma-related activities. Proceeds go to the nonprofit that runs the excellent Bletchley Park museum.
The instructions supplied explain how Pocket Enigma works and take the user step-by-step through the process of coding and decoding. Worked examples and carefully annotated figures illustrate how the Key and Message Setting are used, and there is a trouble-shooting table to help with common errors.
For young readers there is also a simplified way of using it called Junior Pocket Enigma making it suitable for all ages who can read and write their own messages.

Wireless headphones aren’t a mind-bending thing anymore now that Apple made them the standard thing-to-be-outraged-over-in-the-new-iPhone fare, thereby killing the cool factor. But let’s be reasonable here. Wires really are a pain when you’re running, trying to get off the bus, or even just standing up from your desk. Wireless headphones make sense, they just don’t […]
Python is such a commonly used general-purpose programming language and features such (comparatively) simple syntax, that most veteran programmers consider it an excellent foundation for aspiring programmers. The Python 3 Bootcamp Bundle packs over 30 hours of training into nine courses to build that foundation for you.If you’ve never had any introduction to code at […]
