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).
Absolutely right, but of course a straight rod does experience sliding resistance and so, even if we were to call it a buffer instead of an inverter, it would be of little use mechanically. So yes, you can simplify a lot with the relationship between logic level and direction, but as soon as you want to compose more complex functions from multiple mechanical logic gates like this, the inputs and outputs will have to follow the same convention. You can then only make it work by including inverters on the inputs or outputs, and I would see those mechanically as part of the logic gate.
@@arnoud-whizzbizz That would be a great idea. Do you have instructions on which parts to use? Thanks again for the video. Been looking for something like this!
@@Nagermax Don't have a complete list, but the seperate parts are quite easy to find on sites that sell the seperate parts. Only thing I made myself is the slider-bridge: www.printables.com/model/317251-slider-gatebridge-stone-for-fischertechnik
Haha, when fischertechnik introduced the ports in the 1970s, they did indeed use the IEC notation. But even during my own training, in the 1980s, these were still widely used. And actually I like them. As you can see, I now use IEC and DIN interchangeably. That is of course not good at all, but what matters to me is that it is understandable in retrospect 🤔

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.

clever
This is amazing!
Which Fischertechnik kit did you use?
None, only the basic elements. I do still think it would be a great idea for fischertechnik to make a kit like this. I can help :-)

Eeeeugh! IEC gates?? Horrible!

@@arnoud-whizzbizz I can't read them 😂
Edit: after seeing the mechanical gates I was able to understand them better
