Simple LEGO Technic Calculator
Вставка
- Опубліковано 2 жов 2024
- This model is a Simple LEGO Technic Calculator. It can perform additions, subtractions, and calculate the average of two numbers.
Please note that this model is just a proof-of-concept to realise an idea, and that this idea could be extended to create a more comprehensive calculator. This is not a finished model.
Larger numbers could be calculated if the gear racks were longer or a different scale was used on the labels.
This model was inspired by Alex Allmont's Lego analoge adders ( • LEGO analoge adders, v... ).
This model is not an official LEGO set.
This model is not for sale.
I do not have building instructions for this model.

You should scale it up to do 10 digits. Then if you connected another with a pair of 10:1 gear ratios you may be able to do up to 99. But if you add in the gear ratios you could make it stackable maybe. So you could just keep adding place values until the gears run into too much resistance. You would lose the average, but it would be amazing
Wow awesome. I'm blown away with how simple this is.
That's a clever design man!

Move over Texas Instruments
Teacher: Hey! no calculators
Me: i just play with lego
amazing :^0
A little weird, but an awesome consept and build!
This is the best ASMR ever
I'm barely able to make a vending machine out of lego
This is cool. Simple, but cool. Thumbs up.
need this for school. teacher wont know im cheating
For simple math?
I'd be worried if you needed to cheat to find 2+2
Pretty cool. It's so simple but surprisingly effective.
Great work!
OK, please make it now with multiplication and root, thank you.
isnt it just the same as a slide rule?
It's exactly a slide rule.
no, it's not, a slide rule allows you to multiply using logarithms. this "just" adds. but if he had an exponential scale on his cylinder, he would be multiplying the numbers on the left.
of course, but it works on the same principle.
Simple and genious.
I like it!
I think that's pretty smart for a small size and it can do lots
Simple as sht. Wow Great job.
I'm playing with minifigs while this dude is a genious
I'll never cease to be amazed by mechanical computers.
Way simpler than I initially thought (not a bad thing). Nice, clean design.
That’s pretty cool! LEGO is such a versatile medium in which creative minds can express themselves, thank you!
Cool! And very useful also, I always forget what 4+2 is :)
It's cool. But how about negative numbers?
+ForgottenMatter - This is just a prototype to get the idea out there. Of course the idea could be developed further to allow for bigger numbers or negative numbers and you can do this by changing the numbers shown on the the scales. Instead of going from 0 to +4, you could have them going from -2 to +2.
slfroden I can't wait to see the other prototypes you make of this! Do you know when the next legit calculator would be out?
+ForgottenMatter - I have some other ideas for more complex Lego calculators, but I am currently working on some other projects first.
that is simply amazing
That's a very cool construction! Was it hard to come up with it?
+Automatik - Please read the video description to see where I got the inspiration for this model.
I'll definitely give you credit for this, very ingenious design but the subtraction mode isn't really subtraction mode. It's just glorified addition.
Doctor Potassium still gets you the awnser
Subtraction in general = addition. 6 - 3 = 6 + -3 and 6 + 3 = 6 - -3
That's how computers do subtraction as well: they subtract using addition. However, computers use a special binary representation called "two's complement", which is what makes it possible to do subtraction using addition.
ALL subtraction is just glorified addition.
two's compliment also works in decimal. just subtract the value of every digit from 9, then add one (you also do this in binary) to the number you want to subtract, then add that to the number you want to subtract _from,_, then ignore the highest digit:
06 -> 94
15-6 = 15+94 = 109 -> 09
You're a legend
Make this 0-100! :D
+Rèfi Péter - The scales on the sliders can be changed to any number range that you like (including negative numbers).
slfroden 0-10? 😕
+Rèfi Péter - Yes, the scales could be changed to 0-10, or 0-100, or 0-1000000. This is just a proof-of-concept to prove an idea. You could take this idea and extend it further to include any numbers on the scales that you like.
What if you did subtraction that would result in a negative number?
+L J Cohen - With this calculator, the scales that I printed only represent a very small range, and it cannot handle negative numbers.
If you changed the scales used, and moved the zero points, then it would be able to handle negative numbers quite easily.
this is simply amazing!
Didn't make sense at first... but then it all _added_ up.
get out...
ugh
I should be pun-ished for that.
My puns however, are quite pun-ctual.
This is awesome dude, super clever! I love it!
Subbed!
+Brick Off, Eh! - Thanks 😊
No problem buddy, well deserved!
Extremely simple solution, I love it!
very cool!!!!!!!!!!!
So smart
WOW!Really amazing it is genius!
Genius!!!
so cool
Awesome!
Nice build.
Really good idea
You're kinda genius
Cool idea
What's with the average
Are the tires really necessary? Or are they just to make sure it doesn't slide?
+Okay no more redbull - The tires are just to make sure it didn't slide around when I was filming.
What happens if it is 1 - 4. Your calculator does not have any negatives.
+Tim Rinaldi - You can get negatives if you change the scales used.
Awesome. Can u build it with 10 digits?
+@brotschuh - DIY Experte - Yes, you can change the values on the scales to be any numbers that you like.
how long did it take to calculate and discovwr it ?*
+Danchan - Please read the video description to see where I got the inspiration for this model.
so kinda like a mechanical version of a slide rule? interesting..
Sort of like a slide rule, but without the logarithmic scale that makes a slide rule much more interesting.
Imma gonna design and 3d print one of these.
one one hand it's awesome you made such a neat little slide-rule out of lego, on the other hand it makes me sad how few people realize what it is.
Oliver Turner yeah, its cool but it isnt REVOLUTIONARY
So push one of them to for then the other will automatically move to 2 in substation mode
Wish I had this for my calc ap
Share instruction plaese!
I don't have a tutorial or instructions for this model, but if you study the video carefully and have the required Lego pieces you should be able to replicate this model fairly easily.
Awesome!
Simple!
"Simple"lmao that's awesome man!
Nice
Shouldn't you be curing cancer or something?
WOAH. DUDE.
Make a septet calculator that multiplies and divides
Genius
Awesome! This is better than my abacus!
What are the basics of making a lego calculator?
Hmm, that's an interesting question. Perhaps the basics are knowing some math/s, and knowing something about LEGO pieces and techniques.
What do you think the basics are?
very nice! how did oyu mak ethis!!!! can you make instructions?
+Joran Prins - Sorry, I will not be making any instructions for this model, but if you study the video carefully and have the required Lego pieces you should be able to replicate this model fairly easily.
So does it work like a slide rule?
+Epcot lp - If you changed the scales to be logarithmic then it would be more like a slide rule.
Genius!
BakenBaconGaming wat a smart guy
What piece is the wheel in the middle? I can't find it, its name, or its ID.
+Gavin Walker - The 'dial' in the middle is made up of 2 x Technic Wedge Belt Wheel (Pulley) (part 4185). I printed out a strip of paper with the numbers on it and used double sided tape to attach it.
are you planning to make a bigger version? something like +10 to -10?
+bokke vdbergh - To make it go from +10 to -10 would just be a matter of changing the scales that are used. I have no plans to remake this simple calculator, but I have been thinking about how to make a more complex calculator...
what if you choose 0 as the answear? there is only one way: 0+0 so it must not be moveabele but i think that it can move than so it is wrong. can you test it?
ps; i am german and i know that it is not right english what i have written XD
I hope you understand what I mean
+Kerim Ismail - When you want the answer to equal 0 with this design, then there is only one way: 0+0. Also, if you want the answer to equal 8, there is only one way: 4+4. In these situations, the sliders are at the end of their travel, and if you lock the answer to 0, the sliders cannot move at all. Unfortunately I cannot test it as I pulled this model apart many months ago.
Now do division
this is actually possible with logarithms because log A + log B = log AB and log A - log B = log A/B
Very nice !
you are a my new hero man
Do you have a tutorial?
+Da GeckoGaming - I do not have a tutorial or instructions for this model, but if you study the video carefully and have the required Lego pieces you should be able to replicate this model fairly easily.
It is just pulley? Very clever and simple, you deserve LIKE and SUBSCRIBE
+Jakub Pollák - Thanks.
There aren't any pulleys. The two inputs on the left use gear racks. They are joined by a 12-tooth gear, which is connected to another gear rack that moves the two indicators (middle and right).
two racks on left work as rope, and gear is like wheel, so it work as pulley

Digicomp but smaller and made of plastic
Lol "simple"
Felix Heinz it is simple...
nice :D
'simple'
I guess that gear ratio will be difficult to be precise the higher you go maybe. Odd number ratios may not work as lego does not manufacture odd teeth gears. Example: There are 40 teeth gears but not 39 teeth gears.
Amazing
Fantastic!!! Great job bro!! Un saluto dall Italia :)
Genius

SO COOL
cool
Cool.
how to make?
+Abdulhadhi lone - I do not have a tutorial or instructions for this model, but if you study the video carefully and have the required Lego pieces you should be able to replicate this model fairly easily.
slfroden K thx
Fiat thing; that Washington super awesome! But why did you have to hold stil the result? ( I'm not that god at english. hope you understant)
+Linus Vejlø - The position of the result changes depending on which type of calculation you are doing.
If you are doing addition, you control the two sliders, and the dial is free to rotate to give you the answer.
If you are doing subtraction, you control the top slider and the dial, and the bottom slider is free to move to give you the answer.
If you had made it longer ( make the number count higher will it still work? I guess that the average will work, but the adding and subtracting will need a bigger roller in the middle？
+GoldenChicken - You are correct. It could be made longer, but that would require different pieces (the gear racks that I used have a limited about of travel), and the roller in the middle would either need to be bigger (have more teeth), or be geared differently so that it turns the correct amount when moving the sliders. Each new gear that is added may also add backlash into the system, making it less precise.
smart
Dude that's awesome! You made math fun :D
Simple but very cool none the less.
Is there anything preventing you from adding together more numbers? I think it could go at least up to nine.
+jonas knochelmann - The scales on the sliders can be changed to any number range that you like (even negative numbers). But if there are too many numbers then it becomes less accurate.
Cool.
Holly crap, that is amazing
Nice ! I did not know the aler Channel, subscribing! Thank you !
