A World War Two codebreaking machine has been reconstructed after a seven-year project so it can run in public for the first time.

The Heath Robinson has been restored at The National Museum of Computing in Milton Keynes by a team of six.

The machine was an early attempt to automate code-cracking and, due to its complexity, was named after the illustrator W Heath Robinson.

Phil Hayes, of the museum, said the work was “quite an achievement”.

He said it was completed using a hand-drawn circuit diagram along with replica circuits based on 1940s technology.
