Mechanical Logic Gates

The logic AND and OR gates of digital electronics can be regarded as the tangible pioneers of Boolean algebra. After all, hardware programming on printed circuit boards with connections forms the basis of what can nowadays increasingly be solved in software.

I took a step back and played around with the logic functions of these gates using my favorite construction material. And it also turns out that mechanical equivalents of these gates can be used to demonstrate that the functionality of the AND and OR function is mathematically interchangeable.

This video was amazing, and very informative. Everything was very well explained and demonstrated.

Very nice video! The lever does not put energy into the gate. That is a noticable difference to the transistor in electronic gates.

If signals are not defined by their left or right position, but by the fact if they are "in" or "out" then some of these mechanisms get even simpler. Like the inverter could just be a straight rod? Pushed in on the input side (0) - pushed out the output (1). Pulled out on input side (1) - pulled in on output side (0).
