Mechanical calculator
Hi everybody,

I have built a mechanical calculator with continuous carry from standard parts of the fischertechnik construction set, see http://youtu.be/9a_us8rMczw

The Russian mathematician Chebychev (1812-1894) was the first who used an epicyclic gear train to obtain a continuous carry in his 1876 Arithmometer with 20 digits.

Maybe it is of interest to some of you.

Regards,

Thomas
