More interior detail added to #VirtualBombe this week. The rear door now looks more complete and I've added the dials inside which control (and display) the rotor and carry mechanism positions. Will I ever finish? I keep finding new parts to add in! :) @tnmoc @bletchleypark

The Bombe had up to 8 drum types available, colour-coded to show the different wiring of the real #Enigma rotors: I red; II maroon; III green; IV yellow; V brown; VI cobalt (blue); VII jet (black); VIII silver. We'll need to choose from all of them to put on #VirtualBombe. #tnmoc #bletchleypark

The final set of controls are now in place on #VirtualBombe. The switches on the right of the Bombe control which of the 3 chains (the rows of drums) are active, which step and which terminal has the current injected. #tnmoc #bletchleypark

This week, I've been finding out about the "letterbox" display which is situated on the right-hand side of the Turing-Welchman Bombe. For a stop, it shows a possible steckerbrett position (the plugboard cables on the front of Enigma). #VirtualBombe #tnmoc #bletchleypark

The basic wiring layout on the rear of #VirtualBombe is now complete and labelled. I've also been working on enabling the bridges which connect together the input & output of two "Letchworth Enigmas" (1 set of 3 drums which make up an Enigma). #tnmoc #bletchleypark

We'll leave messing with the drums on #VirtualBombe & play with the wiring! The "menu" was wired on the rear of the machine using double ended 26-wire connectors. If you've seen Virtual Enigma, you may recognise my wire physics in action! #tnmoc #bletchleypark #threejs

The Bombe couldn't step the middle row of drums quick enough to keep sensing so for every 3 revolutions of the top drums, the 2nd set would only carry twice. I've been working on duplicating this on #VirtualBombe - details in the video. #tnmoc #bletchleypark #bombe

I've been working hard learning how the Turing-Welchman Bombe does it's thing & coding it into #VirtualBombe.
Finally got some results this morning so let's pop some rotors on and have a quick demo of how it's looking so far. Hope you like it! #tnmoc #bletchleypark #ww2 #cipher

Merry Christmas all! Here's a first early render of a possible #VirtualBombe! Would you like to have your own Bombe and learn how to crack #Enigma messages? yep - me too! Keep following & I'll see what I can do to make that happen.
