Here'a a cool video of Babbage's Difference Engine in operation.

____ Ah, Gentlemen let me take you back to 1964 and SCCA (Sports Car Club of America) and road rallies. Any good winning team Navigator would have at least two stop watches, and a "Curta". These were small compact Difference Engines, made in Germany, most of the time the Navigators equipment cost more than the car s/he was riding in.

My high school maths teacher had one of those, he let me play with it once, truly a marvel of mechanical engineering, but not a Difference Engine.

The Curta was basically a 4-function calculator, the Difference Engine does polynomials, (using the method of differences - hence the name) and was intended to produce navigation tables for the navy, (i.e. calculate trig functions) a task far beyond the Curta's abilities.

btw - do a search for Curta on ebay - they've held their value well.

Excellent video, and a lovely piece of engineering.

Now, I don't know if this works as a real difference engine, but did anyone who followed TFD's link see the Meccano version ?

They were building this in a London museum a few years back adn you could watch them work. It was interesting to watch the finnished product work.
