I have loved learning about this machine and have poured many, many hours into creating this simulation. Do take a look and let me know what you think! If you have an Android phone, try clicking on the "Start AR" option, you may be able to have your very own SG-41 on your table!

Released today: Virtual Schlüsselgerät 41
This cipher machine, based on Hagelin C-38 but WAY more complex was set to replace Enigma.
Over a year of work & research & it's ready for you to try for yourself.

This wristwatch was used from 1974 onward by the German Federal Intelligence Service (BND). It contains a covert transmitter that can be used by an intelligence officer to signal a distress situation. cryptomuseum.com/covert/bugs…

As well as working on modelling & animating the complex paper feed mechanism, I've been having a play adding a few extra visuals. Some useful (hiding specific parts of the mechanism to see how it works) and some just eye candy!

This receiver from Watkins-Johnson played an important role in the Watergate Scandal (1972-1974) that eventually led to the resignation of US President Nixon in 1974. cryptomuseum.com/df/wj/rs111…

I broke more than fixed this week! I'd placed a few items in the machine out of line so last few bits didn't fit in. Had to check scan and correct placing. All fixed now! The question to answer today - "What happens if you run out of paper?" @bletchleypark @tnmoc @cryptomuseum

I've been learning about the SG-41, a mechanical pin-wheel cipher machine, developed as a replacement candidate for Enigma. This is complex, but I'm up for the challenge so ... introducing Virtual SG-41. Follow along as I try to work it out! @bletchleypark @tnmoc @cryptomuseum

Check out this power supply unit of 1965. It was used with the Fialka cipher machine (M-125) and proves that the Russians were well aware of TEMPEST and side-channel attacks. cryptomuseum.com/crypto/fial…

Last Friday, Crypto Museum received a most generous gift in the form of a KL-7 cipher machine, complete with all 12 rotors. It was donated by OVCISKLu -- the Society of Former Signals and CIS Officers of the Royal Dutch Air Force. MANY Thanks! cryptomuseum.com/news/index.…

Lots of work done this week on #VirtualM209, the casing is now almost completed. The ghosted part is a CT scan of a real machine by @dmdmuc (thanks @mgoeggerle). Don't know about you, but I'm really excited about this one, it's looking awesome! @tnmoc @bletchleypark @cryptomuseum

30 years ago, CIA and FBI used this type of equipment for wireless overhearing and recording of conversations and evidence gathering. Now fully functional again. cryptomuseum.com/df/aid/unit…
