Most of us can do simple math in our heads, but some people just can’t seem to add two numbers between 0 and 3 without using paper, like [Aliaksei Zholner] does with his fluidic adder circuit built completely of paper. There’s some good detail in [Aliaksei]’s translated post on the “Only Paper” forum, a Russian site devoted to incredibly detailed models created entirely from paper. [Aliaksei] starts with the basic building blocks of logic circuits, the AND and OR gates. Outputs are determined by the position of double-headed pistons in chambers, with output states indicated by pistons that raise a …read more http://pje.fyi/PM22fH

I was thinking about the analogy between electricity and hydraulics where current & voltage in a cable are compared to the cross-sectional area & pressure in a hose and it got me thinking. "Did anyone ever try to build logic gates with water?" And they sure did!
