Hi ther!
So, i just watched the movie The Imitation Game, and as a electronic hobbyies, i said to my self "why not build a awsome mechanical codebreaker?!"
Example of a code breaker: Bombe - Wikipedia, the free encyclopedia
So my questions to the experts is:
How does a "mecanincal" codebreaker work?
How does the motors/electro magnets in a codebreaker work?
Enyone know of eny blueprints? 
How did they controll the codebreaker, as they didnt have eny prossesing power to controll it i think.
Thanks for eny help! ;D
