I finally made it: an XOR mechanism that requires exactly one of two keys to be inserted at a time. I call it the 🗝️ #keyguardian.
This is very useful for example to track where important small things go: Want to take the car keys? You have to insert your name tag to unlock it.
My first mechanical project with #SolveSpace and it was great!

@nobodyinperson you fool! If you make a physical XOR mechanism, that's dangerously close to making a logic gate. What if someone prints 12 million of these and builds adders and ALUs and memory and now it's running doom!

@JordiGH @nobodyinperson nope! that's merely the most common way.
If you can built logic gates (only certain ones: you need and/or and a not, or a combined NAND/NOR), you can then build a computer out them.
Those logic gates can be made out of anything though. Electron tubes, gears, falling marbles, crabs, etc...

@foone @nobodyinperson I thought to run Doom we needed to first flatten a rock and then run lightning through it.
