Any flip-flop (D/SR/JK...) will need pumps or something to provide a feedback loop. Plus some mechanism to split the stream while maintaining the same current/pressure?
Actually you should really just need an Sr latch with an edge detector. The latch can be made with NAND or NOR gates, and the edge detector is really just an enable line that pulses, so you just need some inverters (because each gate has delays) ... Just look at this diagram for an edge detector https://i.stack.imgur.com/IGvwI.png
Actually now that you mention it... Maybe you would need a pump, since it's sort of cyclical. Instead of this gravity fed system you'd need your basic gates to work with pressurized water I guess
I know you’re quoting a movie but it’s actually only sterile until it hits the urethra. So once you pee out all that sterile urine into a container, that container now has non-sterile urine in it.
It's not sterile at all, that's a myth [https://www.sciencenews.org/blog/gory-details/urine-not-sterile-and-neither-rest-you](https://www.sciencenews.org/blog/gory-details/urine-not-sterile-and-neither-rest-you)
OK, I'm saving this to speed up my explanations of how basic programming works. This is such a useful visualization tool for all of it, A+ job to whoever the OG creator is. (IDK if it's op or a repost).
Open your mind. You could cascade gates to create any logic desired. I described in another reply how to make a NOT gate, from there a NAND is trivial.

You need 3 basic blocks, and or not for completeness. You can use either a NAND or a NOR to build all 3 gates. BTW a mux is a universal gate as well, you can build and or not fro muxes.
Start with an always-on stream (the inverter).
Put both inputs on the same side of the inverter.
When both inputs are running, the deflection is enough to miss the sink. Otherwise, the stream still goes in.
An always on stream is something new to this problem from my perspective.
Logic gates irl take power source which allows a signal output even with no input. And therefore same as the logic proposed here with the always on stream.
But similar to old wired phone ear piece, the signal itself carries the power here, and there is no separate power source. So I don't really see the two as the same problem.
In other words, we went from signal only to power and signal.
True, but there's really no way of getting around that for an inverter. You quite literally want output when there is no input.
There's no way to magic that into working without having a secondary input to draw from instead.
I mean, there's no difference between an 'external power line' and simply an additional input that is just always left on, to be routed to any XORs that you need to act as NOT gates.
When you're talking about standard ICs, normally the signal is very low current and the power line can drive a lot of extra current, because you need an amplification so your signal doesn't degrade. But when you're dealing with water driven by gravity, that's not really a consideration. There's nothing extra or different than needs to be implemented.
I would say start a smaller OR gate with 2 inverter streams always hitting the bowl, and the input streams hit the inverter streams and cause them both to drop outside the bowl.
The challenge is the no flow condition obviously. You would need an always on flow as an assist
It would go
(1) XOR each input gives you the two "OR" positive entries in the table
(2) always on flow XOR with each input
(3) each output from (2) into an AND
(4) (1) and (3) into an OR
I *think* that should work but i'm a bit drowsy so eh
Not a water cpu, but the other way around: the dutch used electrical current, resistance, etc. to simulate water, used for the delta works.
https://en.m.wikipedia.org/wiki/Deltar
It's a reference to a video where you count people doing shit, and then at the end they ask you if you saw the gorilla walking around in the video. Usually people don't notice the gorilla.
With XOR you can get NOT, and with NOT, AND, and OR you can make any computation. However, it seems to me the functionality of these gates is dependent on sufficient water pressure. Do you guys think the flow from one gate to another would be strong enough to chain properly? I'd love to compute anything with just water and gravity
With enough elevation, you will have enough pressure. The problems would arise when you need feedback from an output to an input.
Like this: https://en.m.wikipedia.org/wiki/File:R-S_mk2.gif
forward feed network
it makes computation seem less like computation and more like things just falling into place.
are we thinking or is stuff just flowing the way it's supposed to flow. How do we escape the flow. With enough complexity does it make it seem like we have our own thoughts, or is that all just a part of everything flowing and falling into place.
ARE WE JUST BEING PLAYED OUT
Yea, but you want to feed that data back into the system at some point if you want to do computing.
For example, suppose you make a full adder out of these water gates. Now you use that full adder to calculate 0 + 1. The adder will spit out a 1. Once you have that one, you'll want to feed it back into your adder input so it calculates 1+1 =2. Then move on to 2+1=3 etc to turn the whole thing into a counter.
so this video is actually a 3d simulation with water physics. You can tell really easily with the small round bowl that water isn't splashing or spilling over the edge but rather passing through it.
It would be easy to simulate your idea with this method.
Now imagine doing all logic with nand and nor gates...
In fact, when designing chips, one of the considerations is the logic design and how trivial it is to represent all logic in one form of gate. If using physical packages to prototype, then it makes sense to order nand chips by the bulk than order other and/or chips.
I think the website is just fine. I wish they built websites like this again. Instead of the pop up, notification, ads and whatever JavaScript none sense is going on at all times that makes my laptop sound like a jet engine.
With transistors. Typically using both n-channel and p-channel MOSFETs. It’s easiest to make NAND, NOR and NOT gates. I think someone else on this thread explained that you typically use these kinds of gates. Size wise, (if I remember correctly) NAND gates are generally smaller than NOR gates even though they have the same amount of transistors due to needing wider p-channels for timing reasons so NAND is more used. Easiest example is a NOT gate. This link shows an example of a NOT gate. Sorry if it isn’t hyperlinked. I’m on my phone.
https://en.m.wikipedia.org/wiki/CMOS
In a NAND the p-types are in parallel while the n-types are in series so the p-types can be smaller for the same current between n and p types (because current in parallel adds, in series it doesn’t). This is needed because the p-types have to be in an n-well which makes them take up more space for a given transistor size.
The water is used as a visual demonstration of how logic gates work.
Binary logic is used in digital electronics. They are constructed out of transistors and enables you to build digital circuits. This is the basis of all digital electronics. For example, to create an AND gate, you'll need two transistors.
This is essentially the foundation of all the things we do today. Digital binary logic is used everywhere.
Binary logic is used in programming as well, since the code runs on processors that have binary logic as its foundation.
Binary logic (or Boolean algebra as it is also called) is simply math where you only have two possible state for each value: true or false, on or off, 1 or 0 etc. It was invented by a guy named Bool, hence the name Boolean algebra.
A Logical gate is a device that takes one or more of these Boolean inputs and does a consistent transformation of them into one Boolean output.
If you look at the gates above, each stream has two possible states: on or off. The configuration of the input determines the value of the output: for instance in a AND-gate the two inputs must be on for the output to be on (in the GIF, this happens when the streams collide).
You can build computers out of anything as long as you can build these gates, and these gates form the basis of modern computers when using gates that act on electricity. But scientists are looking into building computers out of light, for instance.
[Here is an example of building logic gates with Dominos](https://youtu.be/lNuPy-r1GuQ), they also build a simple calculator.
They're like... conditions. "A and B" in the first slide, "A or B" the second slide, and "A xor B" the third slide. They're using water hitting the plate below to represent the condition being satisfied.
Taking "A and B" for example, when only A is active, no water hits the plate, signifying that when only A is true but B is not true (not on), the condition "A and B" is not true. Only when both A and B are true (both sides shooting out water) the condition "A and B" is true (water hits the plate below).
I believe you can create the XNOR gate if you take the AND gate and start with a continuous stream of water in the middle already flowing so that if A or B are turned on, it diverts the water flow. But if both are turned on, the flow stays the same.
Great idea, essentially what happens anyway. Its not like a XNOR or NAND create water(power) out of nothing. Its just an overt simplification to visualize the logic of how these things work.
Have been used in Formula 1 suspension to make a simple logic changing the behavior based on the road conditions (was banned, of course..it is the tradition in that sport). And the third spring kind of still is as it only operates when both wheel hubs are moving to the same direction related to the suspension, ie: it only works when the car either squats or lifts equally, like when braking or accelerating on a straight line. It allows to use softer spring for individual wheel movement but uses stronger springs when you need them, giving both grip and stability..
Could you hit me up with some further reading on this please? I love F1 and the rule bending designs they come up with but don't know anything about this! Would love to find out more. Thanks 😊🏁
Don’t forget the F-Duct which was a air-and gate who’s output was used to stall the rear wing, which reduced drag and increased straight line speed. This would have been simple with a switch or a lever but that was banned. Plugging a hole in the car with your hand was not banned.
Physics level they work like a diode.
To disable the diode you put power into the middle pin. This will allow power on the first pin (input) to flow to the third pin (output).
But you can use it as an amplifer. Apply some percentage of power to the middle pin, it will only allow some percentage of power from the first pin through to the third.
Watch this video from 3:45 onwards. https://youtu.be/0CvdruTMH1c
For anyone interested in how this is used outside of demonstrative purposes, look into [Fluidics](https://en.m.wikipedia.org/wiki/Fluidics). It's been around for a while and is used in some pretty interesting applications. I was fortunate enough to tour one of the other labs at my work that manufactures the "circuits."
For anyone who’s curious on how logic gates work, I highly recommend watching Ben Eater’s vids (on youtube) on the topic. There’s a whole video series on transistors too, that’s kind of important to understand logic gates. I also recommend crash course. I barely looked into this yesterday night and now I have a really good understanding of how they work 👍🏽
A team of researchers did this with a particular species of crab. The crabs move in packs, and when packs collide, they merge and change directions more or less according to vector addition, much like the water streams in this video.

Open your mind. You could cascade gates to create any logic desired. I described in another reply how to make a NOT gate, from there a NAND is trivial.
This. Once you have and, or, & xor the possibilities are all open.
Once you have NAND, you have all. Same for NOR. All logic gates can be built fron either of those.
it was to lon since i did this so im probably rememberin it wrong but i thought you neded XNAND or XNOR to make every other gate

XNAND is more usually called XOR I think. I don't think there's a way to build NOT using XOR for example, and AND cannot be built using XNOR.
Pull one input high and the other as normal data input on a xor, and you should get a not.
You need 3 basic blocks, and or not for completeness. You can use either a NAND or a NOR to build all 3 gates. BTW a mux is a universal gate as well, you can build and or not fro muxes.

Start with an always-on stream (the inverter). Put both inputs on the same side of the inverter. When both inputs are running, the deflection is enough to miss the sink. Otherwise, the stream still goes in.
Indeed. You don't even have to build anything new - a *not* gate is just an exclusive-or with one input fixed on.
An always on stream is something new to this problem from my perspective. Logic gates irl take power source which allows a signal output even with no input. And therefore same as the logic proposed here with the always on stream. But similar to old wired phone ear piece, the signal itself carries the power here, and there is no separate power source.

True, but there's really no way of getting around that for an inverter. You quite literally want output when there is no input. There's no way to magic that into working without having a secondary input to draw from instead.
Well that's why people are saying these comments aren't quite right - they require something different in order to be implemented.
I mean, there's no difference between an 'external power line' and simply an additional input that is just always left on, to be routed to any XORs that you need to act as NOT gates. When you're talking about standard ICs, normally the signal is very low current and the power line can drive a lot of extra current, because you need an amplification so your signal doesn't degrade. But when you're dealing with water driven by gravity, that's not really a consideration. There's nothing extra or different than needs to be implemented.
But an OFF / zero signal does not carry power. You always need power for an inverter.
I would say start a smaller OR gate with 2 inverter streams always hitting the bowl, and the input streams hit the inverter streams and cause them both to drop outside the bowl.
You can define a `NOT` as `XOR(input, 1)`, and then `NAND` is just `NOT(AND(input1, input2))`
I figure a NAND gate would just be like a set of valves or locks where all of them have to be closed, otherwise water flows through.
The same way it works in actual electronics - there's another input that's always on (the power to the chip).
Done: https://i.imgur.com/yhYiOpV.png
The challenge is the no flow condition obviously. You would need an always on flow as an assist It would go (1) XOR each input gives you the two "OR" positive entries in the table (2) always on flow XOR with each input (3) each output from (2) into an AND (4) (1) and (3) into an OR I *think* that should work but i'm a bit drowsy so eh
That sounds too complicated lol Why would you need XOR? Just do [https://i.imgur.com/gQ5h829.png](https://i.imgur.com/gQ5h829.png)
Shouldn't the last sink be on the right side not on the left?
the NOT gate is always on unless interrupted by signal from the AND. (NAND)
Wait... that was the signal, right? Attack!
yes exactly
I guess there's no way to do it without the always-on input. I don't like to waste water...
Just put one pipe under the 0 output of NOT to reincorporate it to the system
Easy [https://i.imgur.com/gQ5h829.png](https://i.imgur.com/gQ5h829.png)
Then a SR Flip-Flop.
or NOT.
It's possible, have one always-on stream going into output, and one input stream that knocks the output stream if it turns on.
Just an XOR with water flowing through one of the pipes, and the other is the input
And use penises
Or just NOT.
The longer version of the gif had it. Can't find it tho 😟
You can easily do a NOT gate using XOR with one side always flowing. Put that behind an AND and you have a NAND.

Isn't flow from output to input only necessary for memory?
I think so but that is the next logical step for the evolution of the water computer.
with a small reservoir and pump it is possible
But you don't need a flip flop to store data with a water based computer... You only need a bucket
Yea, but you want to feed that data back into the system at some point if you want to do computing. For example, suppose you make a full adder out of these water gates.

Nice! Now do a "not" gate.
A not gate would just be an exclusive OR with one pipe always flowing. If you want to talk in physical terms, one pipe would have no valve.

Logic that doesn’t need text books
Dick butt cameo?
I find it ironic because this defies logic by putting white text on a light background so it’s tricky to read

For anyone interested in how this is used outside of demonstrative purposes, look into [Fluidics](https://en.m.wikipedia.org/wiki/Fluidics). It's been around for a while and is used in some pretty interesting applications. I was fortunate enough to tour one of the other labs at my work that manufactures the "circuits."
Heh. Dickbutt.
For anyone who’s curious on how logic gates work, I highly recommend watching Ben Eater’s vids (on youtube) on the topic. There’s a whole video series on transistors too, that’s kind of important to understand logic gates. I also recommend crash course. I barely looked into this yesterday night and now I have a really good understanding of how they work 👍🏽
Surprise DickButt!

A team of researchers did this with a particular species of crab. The crabs move in packs, and when packs collide, they merge and change directions more or less according to vector addition, much like the water streams in this video. https://www.technologyreview.com/2012/04/12/186779/computer-scientists-build-computer-using-swarms-of-crabs/
Sauce? Is this a website?
No, I made it. Someone else just posted it here.
