I Made A Water Computer And It Actually Works

Computers add numbers together using logic gates built out of transistors. But they don't have to be! They can be built out of greedy cup siphons instead! I used specially designed siphones to works as XOR and AND gates and chained them together so they add 4 digit binary numbers.

I love how an overflow error literally results in an overflow of water.
-
Man, seeing the siphons finally pass over the threshold, and start dumping out their contents... is so satisfying
-
Oh, I've never actually understood how logic gates work with binary addition before. I "learned" it in school, but never understood. This is such a clear explanation. Thank you!

In middle school I forgot about finishing my science fair project, and seeing it was due on that day, I rushed to make an analog water computer to determine the weather. If you go outside and it is raining, then it is rain today. It was a very simple design.

I think this would work a lot better with mercury; it’s not as sticky.
-
It's weird seeing my same minecraft Redstone circuits made from water and actually understanding what's going on
-
A memory leak 😂 I've watched a lot of your puns Matt bit I've never laughed this hard!
-
13:45 this one scene just did more for me to understand computers and why they work, visually, than any other video on the internet. I get it now.

"I have a water computer" "Cool, do you mean water-cooled?" "No"

You've got a memory leak 😂

This is so cool. My uncle, Bill Horton, did a ton of early research on fluidics and the fields use in computing, he would have loved to see this and how accessible it is to people.
-
"Wet Inside" LOL, this made my day
-
The real question is: "Can it run Doom?"
-
"have you tried turning it off and on again?" "Yeah standby" tips the computer upside down
-
I'm more of a practical learner so while I understood the purpose of logic gates and what they do in theory, I now have a better understanding of HOW they work. This was perfect for me, thank you.
-
This is some really nice work! I actually used the logic gates from this to make my own computer and it ran flawlessly, I don’t know how to thank you enough for this. This also got me into addition calculations of computers as it’s mesmerizing to watch as something works with another thing to get a result

Btw. I think there is a way to turn this into a digital number once again: Once all individual "buckets" have settled, you could put the fluid from each bucket onto a lever scale and put them at the corresponding distance to the center such that their pull on the lever corresponds to their number. So meaning: 8 _ _ _ 4 _ 2 1 | _ _ _ "measure" (maybe with a spring and a ruler). The number 8 corresponds to the fluid in the bucket which has the bit for 8 for example.
