Because these scissors become loose after several logic gates, you need a component to amplify this signal, ideally using external power (otherwise the mechanism would become very stiff). I'd suggest possibly using a worm gear.

Would be nice to see a full 4/8 bit signed adder with Lego scissors. But because of the wigglines you would need a mechanism that would renew the strength, like a redstone repeater. Maybe with a rubber band?
@in1
@in1 11 месяцев назад
A repeater would unfortunately need some kind of power source, so it would need to be something like a lever connected to a servo motor. But of course that would get really expensive pretty quickly...
@bowfuz
@bowfuz 11 месяцев назад
That's true, things get all jammed up with enough depth. A rubber band wouldnt quite do the trick though, 2in1 is right about needing external power for some or all gates, and the neat thing with that is if it's done right, you could have it take so little input force / movement to get a much greater output force / movement, and thus, something like a delay line memory is possible, or a NOT gate feeding into itself, or any number of things!

@@Ailtir for a little bit probably, but resistance will still add up. It's much better to not have the gates bearing significant force and instead control how much power they draw from another source, with as little energy into the inputs as possible. Think of it like stepping on the gas. You aren't pushing the car forward, you're just controlling what the engine does. And if you had one car roped to the gas pedal of another, you could effectively slam the gas for the other car just by tapping the gas in yours.

@secondengineer9814
@secondengineer9814 11 месяцев назад
One thing that might be interesting to have is a repeater. Something that takes a high or low signal and digitizes it to be fully 1 or 0. I.e. If the output of the half adder is 75% when it should be 1, you could have a circuit that turns >70% signals into a 100% signal
@in1
@in1 11 месяцев назад
The problem is just that the force of the output is too small, so you can't really build something with rubber bands to amplify it (otherwise, you would have found aa way to create energy from nothing), but you need a motor
@MinerBat
@MinerBat 11 месяцев назад
this is like the time i made mechganical logic gates in kerbal space program lol. shame that resistance would add up if you connect too many logic gates and the elastic bouncy things (idk the english word) would not have anough force to pull things back after a certain point... would be cool to have solutions like logic gates controlling motors controlling more logic gates which would overcome those problems, but that would take a lot of motors... it would theoretically be possible to make a full computer i think! i hope to do that one day if i ever have enough money for that much lego

That would actually work! The only problem is that you create some kind of lever, so the output moves only half of the way, but by changing the output scissor you could fix that. I just settled on my design, because it was more reliable.

@steinlaus5605
@steinlaus5605 10 месяцев назад
Instead of working with sissors we could use axles. Or: two pushing against a beam, Not: one pushing against a joined beam retracting its other side, And: a joined beam must be pushed by both sides to slide upwards....
@steinlaus5605
@steinlaus5605 10 месяцев назад
Works but even then NOTs are long and AND seems very hard first... but its only an angle where you push on the sides. If no force is on the other side the input is the first one triggered and if not it cannot go back and push forward. Could be easier build an adder with that...

Very cool video!!! And very interesting new concept for mechanical computation! One drawback of this approach is the need for rubber bands or friction. This means that if you connect gates in series, the strength required to activate the inputs grows linearly with the depth of the circuit, which makes it unfeasible to build large circuits. The coolest technique I know of for mechanical logic is Konrad Zuse's idea of using plates (see his mechanical Z1 computer built in the 30s, which was super cool!), which does not have this problem, and is quite easy to replicate with Lego: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Rwx0WdOQ9yc.html

@nitt346
@nitt346 11 месяцев назад
There is an additional issue with rubber bands - that the force applied backwards through the system by one rubber band can counteract the usefulness of an earlier rubber band. For instance, consider you have a simple sequence with an OR gate, connected to a NOT gate, then the output is put into both inputs of a second OR gate, (i.e. =OR-NOT-=OR-). The rubber band in the second OR gate is pushing its inputs to be 0, which then pushes the output of the first OR gate to be 1 (due to the NOT), cancelling out the effect of the first OR gate's rubber band.
@nitt346
@nitt346 11 месяцев назад
In general, creating static mechanical logic gates seems to be pretty tough, because you have to introduce a natural asymmetry (the OR gate "wants" to be 0 in more cases than it "wants" to be 1), without adding forces within the system that could leak into other gates and unbalance each other. Great video!
@in1
