A Mechanical Calculator in LEGO

- 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,
2in1
--------------------------------------------------------------
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:

Division by zero is undefined i.e. it breaks the machine 😉
Litterally
Why? Zero by zero divides quite easy :)))
@@DanielLenskiy Yeah, but in this case you can move the output freely, which means the result of 0/0 isn't defined
Imagine going to school and whipping out these things
Imagine using the multiplication calculator and 1 of the 2 adders in order to simulate a simple neural network
Plus there is another better way to add. Use a system similar to those to input phone numbers on old telephones
yes 2x1=1
The teacher:wtf
@@MrYeast-rq5ox wtf its 2 not 1
5:56
Teacher: how many is 2x1
2in1 Bricking is 1
Should've used my calculator :)
@@in1But real answer is 2 not 1 go edit your Multiplication machiner Now!
If you used this in school you will got C-
Step 1:
Get a technic pin
Step 2:
Build a 4 bit adder
Step 3:
Build an ALU
Step 4:
Build a laptop
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.
Bouta be the coolest kid in elementary school when you rock up with this
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?
Another great video, never thought of doing this! (nice refrence in the thumbnail too)
Another great build!
Sickkkk great work!
For the 1st adder, it almost looks like you made a slide rule out of Lego!
teacher said no calculators so i brung thes
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
5:56 hmm didn't know 1x2 is 1
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.
Bro really said 🧱🧮🔨💥
5:55 actually 2x1 = 2
Day 4 of asking for a 7 segment display.
Cool! Did you desing this yourself?
I don't exactly know who designed the linkages, but the implementation in Lego is designed by me
How do you know the logic to build the things?
The linkages are not designed by me (you can find them on TH-cam), what I do is trying to build them in Lego
how to make things move without using motor like when it touches a wall or idk :)
Also, another question: Is it possible to make something like gear ratio (speed change)
without gears? That's also important for me.
The only valid alternative would be a belt (rubber band + wheel), everything else doesn't hav a ratio
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.
👍👍👍
Wow
Could you please make a video about how to make super fast gear ratio without many gears?
big gears and tiny gears
@@DarkShard5728 Man,
did you even read what I wrote?
"...without many gears"
I don't have many gears, I have 2 medium sized and many small.
I need fast gear ratio for my clock, and I don't really know how to make it without
"big gears and tiny gears".
I'm asking for REALLY FAST GEAR RATIO WITHOUT MANY GEARS.
@@adamgarbaczewski hey uh dumbass
size =/= quantity. many means a large quantity. and how am i supposed to know what gears you have? also, im pretty sure the only way to make a high gear ratio is literally just big and small gears, so go buy some if you need a high gear ratio
@@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 TH-cam 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)
Also, I don't need any mean, bad answers, I want polite help.
Since when did 2x1=1? It's 2
6:01 2x1=1 really???
5.56 2x1=1 WTH
2x1=2 bruh
What about algebra
2 x 1 = 1 ???
Can you Divided by Zero, I want see what be happened 7:07
5:58
2 × 1 = 1???
5:55 - ," 2 x 1 = 1 "
Yep, I copypasted the text around and forgot to change the result
Are you french ?
Because your pseudo is in french
Probably YT auto translate
Hi hihihihihijihihhiihi
Imagine making it for cheating
у меня нет деталей
2х1=1????🤦
Я перший👑👑👑👑👑👑👑
Seriously?
5:57 - 2*1=1?
How can you even write this without noticing? You should be careful when revising your work...
:) Yeah, I was extremely tired when editing the video
@@in1 that's only a typo, you made a great job of designing / building the mechanism 🤩
Pls stop
@@kino_61 Indeed the concept is still cool. With softer and more reliable mouvements you could make a nice calculator.
Not very nice responding like that :/
5:57 2 * 1 = 1 ...
2 * 1 = 2
you can't just change what the numbers are on screen .. thats not how this works
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...
