A Mechanical Calculator in LEGO
Ғылым және технология
Hi, here are 3 linkages you can use to actually calculate things. It's probably not accurate enough to use it in real life, but it's definitely a neat mechanical principle.
Enjoy watching,

I don't really know who to give credit to since I don't really know who invented the mechanisms originally, but @thang010146 was a really helpful resource for the project.
The Lego builds are my own design, of course.

For people interested to know more about these sorts of mechanisms, this old military training video is fabulous: kzread.info/dash/bejne/pWWdj8ancaufiZc.html
Division by zero is undefined i.e. it breaks the machine 😉

For multiplication you're better off using addition with a logarithmic scale (so you'd need two stickers of logarithmic scales, and because of how that works that means you can use it for any power of 10 you want. If you hook up the addition output to a 2:1 movement reducer then you can even make the inputs and outputs line up exactly)

You're right, if you don't need a linear scale, you can multiply a lot easier.
Another great video, never thought of doing this! (nice refrence in the thumbnail too)
For the 1st adder, it almost looks like you made a slide rule out of Lego!
Another great build!
So the multiplication device is literally changing the slope of a linear equation? Input 2 adjusts the height of each step while input 1 decides how many steps to walk up that slope?
Sickkkk great work!
teacher said no calculators so i brung thes
Bro really said 🧱🧮🔨💥
There exist tiles that have numbers on them. You should get some of these. I'm not sure any of these do any calculation themselves, and are merely sliderules, tools used to help humans commit calculations.

Well a calculator is just fancy electronic stuff too, that converts button presses to 7-segment-output. So it's also just a tool, the one who has to read the output is still human like in the Lego Machine.
5:56 hmm didn't know 1x2 is 1
5:55 actually 2x1 = 2
Should there not be some conversion with trigonometrics? is the scale really linear?

It is linear, because I don't directly change the angle, but the slope
Cool! Did you desing this yourself?

@@DarkShard5728 Even ignoring the fact that I was not asking you (I understand you tried to help)... really, if I'm asking: "How to make gear ratio in *some way*", that means that I know how to make a big-to-tiny gear ratio and I'm asking for the alternative. And really, how often do you see the gear ratio with 4 gears and the size comparison like 10 to 1? It's obvious that the simple "big gears and tiny gears" is not what I need. Also, why do you call me dumbass? If you want to help, then get some knowledge, ask me for precising my question, and then answer. (PS. And that's OBVIOUS, that I'm not English , so asking for precising is really not a bad idea). (PPS. Yeah, this comment is getting long, but I need to say: why a total noob in mechanics would go here and ask, how to make a gear ratio with big and small gears? If he knows what's the gear ratio, then it's obvious that he knows that the bigger gear gets, the faster the tinier gear will spin. I have the harder, not simpliest questions, I was looking in KZread and no one really made the video about what I need, so if really I would have that simple question, I wouldn't need to comment, just use Mr. Google). (PPPS. Not really sure if I'm writing clearly, because I'm Polish not English, so I POLITELY apologize if something is unclear). (EDIT: Oh he deleted his comment, nevermind :D)

Linear motion can be multiplied/reduced using a sliding mechanism like the one shown in the video, but for rotary motion you need gears or belts.

I mean the question is what you need. If you want to calculate big numbers, you can build a big scale (for example with number tiles), if not you can build a small one. You definitely don't have to change the numbers, I just wanted to show how it works with small and big humbers...
