The Digicomp was actually on my long-term list of things to make, but you beat me to it! :)
Many thanks also for making instructions. I'll definitely be making one of these...

Very simple and very clever I think, the planimeters are awesome object ! I plan to build some other, include polar and orthogonal for the exhibitions at fanabriques in june, 2013.

Nothing ! Juste a 40/8 gearing. The aim is only math : the green's theorem : http://en.wikipedia....n's_theorem The trick is that the angle between the begining and the final position is arround equal to the double integral because the cursor follow a tractrix which is arround equal to the derivative underneath the curve, and the double integral is the surface thanks to green's theorem.
Some readings :
ps : yes I will make instructions, it is very basic.
