How the Arithmometer Works

The Arithmometer invented by Thomas de Colmar was the first mass produced and marketed mechanical calculator. This video describes in detail how the Arithmometer works.

So ingenious and intricate... Reading about it just doesn't do it justice.

The Curta calculator looks like a direct descendant of the Arithmometer. The Curta seems to take all the Leibniz wheels and replace it with one common wheel to make a much more compact machine. Watch the Curta video by MechanicalComputing.

It is amazing to see how people solved these problems before the advent of electronics.

very instructional and well done video! I've been reading a lot about the Arithmometer and I hope soon to post a video with a lego replica.

Amazing video! I really appreciate the work you put into these videos. Can you do one on the more advanced machines like Madas 20? How about a cash register?

Fascinating stuff. What are you using for the visualizations? Do you know of anyone trying to 3D print a working example, even of just a single cylinder?

What software do you use to generate these models?
