That's pretty smart. I think your bottom right gate should be a NOT instead of a XOR though. I'm used to seeing gates that only have 2 inputs, so I'm not sure how a XOR gate with 3 inputs is supposed to react. Again, good job. 10/10 for posting something smart.

I dont understand how to do it. The description and instruction you gave me didnt really help a lot either. So can someone explain to me how to use it? But still, i think it is interesting and smart.

you could just say Inverter for the last one 10/10

Quick, somebody make a full adder!

It seems a bit fragile, and with not more than 10 gates, it gets laggy.

Nice, although they are a bit fragile like conun said.

sorry, thats right. but i hope it is just a problem of the simulation. i expect that the advantages will come out in real life as far as bigger possible circuits are mentioned.

i want to repeat, that the spring free construction MAYBE doesnt need so high input forces - espacially at a bigger amount of gates in series. that was the reason, why i designed them.

however, thank you for the feedback, doesnt matter if good or negative.
