Active mechanical logic gates

[Thomas Puettmann]

Hello,

not yet a calculator, but hopefully on the way towards it:

The project aims to mimic electronic digital logic purely mechanically (except for a motor, which could be substituted by a windmill or a steam engine).

My idea is that the educational value is that you can see, hear, and feel everything that is going on (in particular, the amplification) unlike in electronics where ICs are black boxes.

More complicated flipflops and a minimized full adder are on the way.

One of my goals is a small 4-bit RPN calculator (most probably just with + and -).

The project is of course completely open and purely educational.
