A Finished Babbage Difference Engine!

Sheldonista Beau V. sent in this link...of a fully built Babbage difference engine. So, so rad. I had no idea anyone had ever completed one.

You're right, this is very, very cool. I can only imagine how much this cost to make a reality. Brilliant!

Kind of curious about the guy that commissioned the engine.

http://en.wikipedia.org/wiki/Nathan_Myhrvold

The above is a link to the Wikipedia page on Nathan Myhrvold, who commissioned the building of his own Difference Engine No.2. The man in the above video is Doron Swade, who was head of the project to build the first engine for a museum in London. He's also written a book on the saga to do such. The link below is to a Youtube video of a panel where Swade and Myhrvold lecture on the engine at the Computer History Museum.

31 decimal digits? Kind of puts 64-bit computing into perspective.

In Response to remdog (#58452):

Not sure about K'nex, but there's one made from Lego here:
