- I hope you enjoyed the video!
It was quite hard pushing it to its limit, but it was worth it!
*At 5:08 I meant "break" and at 5:45 "vibrates"... I really don't know how this happened 🥲
- A tyre of a car going at 50 kmh or 30 mph spins like 26 times slower than this engine...
- The first version: • Testing a 8,100 rpm Le...
- The way I measured all the results is quite useful but not totally accurate... So it can sometimes deviate by a few rotations...
- If you didn't really understood how I calculated the speed:
It's quite simple...
I know that when the orange thing does one rotation, the propeller has completed 576. Then I stop the time measuring how long it takes the orange thing to do one rotation (the propeller 576). Then I divide 576 by the measured time, so I know how many rotations it does in one second. Finally I multiply it by 60 to get to rpm's (rotations per minute).

For you future projects i would recommend using WD40 for a lubricant, as water (in most cases) will slow you down due to it wanting to stick to itself and as well as the rotating parts. However, i understand if you don't like the idea of oily residue on your legos.
Silicone lubricant is far better for lego
I did it first with water and noticed how much it spread on my table, so I decided to stay with it... Maybe next time I'll try it...
What about graphite from a pencil? I’ve seen other people use it as a lubricant before
@@jonathanroell8342 Good idea! Thanks!
wd40 isn;t really the best lube tbh, its only marginally better than water and is very short term
something like bike chain lube would probably work best here
Oh hey, that was my record!! I guess I’ll have to go back to the drawing board and give it another go! Congratulations and nice build!!
I know bro, now it's mine...😏 I would like to see a second version of your model!
Bro we need a series of back and forth faster and faster! It’d give you more motivation

@@Marder_IFV we met before?
Use a rpm reading thing. The gears used to measure the rpm put a lot of drag on the system. You can hear there is a big difference with the rpm with and without
Yeah, without it, it would be definitely faster!
There's another way you can estimate speed - sound. Record the audio with it spinning at a known speed. Put the audio in a audio program (like Audacity) and have it do a spectrogram. You should see a strong peak at the known speed. That corresponds to the speed (albeit in revolutions per second instead of minute) or a multiple of it. Then take the gears off and repeat. You should see that peak move, so now you can recalculate and get the speed.
Worm gears are famously inefficient. Like 50% efficient. If he needs to record speed but needs a reduced output, use spur gears, as they're typically 99-99.9% efficient. I've had extremely low power systems with 300:1 spur gear reductions run totally fine, but one worm gear, regardless of the ratio, will kill the same motor.
@@LucasDynamics just use an IR laser to detect the revolutions.
@@Ghorda9Bingo! I was thinking a hall effect but your idea would be 🤏 that much more accurate. 😁👍
*At 5:08 I meant "break" and at 5:45 "vibrates"... I really don't know how this happened 🥲
it may vibrate due to imbalance, like one moving part is slightly heavier or lighter than others
might just be the air moving real fast
might be friction between parts
also powd graphite is a lubricant, literally just pencil lead but crushed up
@@JustTheRat01 he means he doesn't know how he made that mistake
@@DAVISTHEDUDE_ my bad i was just tryna help
Oh, I get it, it seems that you're getting light lag. You're at a point the RPM becomes its own gravity, causing the weaker side to break. That's just a theory.

4:10 ..... That crack sound was amazing
😅
Remember, tightening the gap in the top only decreases power, as the rotating fins are pushing against the suction there.
You mean the first version?
But generally, where do they rotate against the vacuum?
@@LucasDynamics That threw me for a loop for a minute lol.
Thats like resticting the exhaust

When you are so much into legos that durability of the parts becomes and issue. Btw this was really cool. Gz man

HUGE TIP: Use graphite powder as a lubricant.
I will!
@@LucasDynamics😁✌️
@LucasDynamics Also using the gear reduction to measure is smart but remember it adds load to the system leeching power.
@@faraday9234Yeah I will use a laser measurement tool next time...
I think it would be faster if it didn’t have to spin the rpm calculator
Yeah, it would make quite a difference! But until I have such a laser measurement device, I have to use those gears...
Water isn't a lubricant, it's an abrasive...
You need oil. Plain oil, olive oil, motor oil, whatever oil. But an oil.
Or Graphite...
no fossil fuel based oil, it would destroy the plastic.
Lithium grease would work, right?
@@swealerYeah!
Ah yeah. Oil right into the vacuum. Genius.
That's absolutely amazing bro! That's cool as hell!
Glad you like it!
You built the Mazda 7vacuum7b! Congratulations 👏🏻👏🏻👏🏻👍🏻. Sounds so great in the beginning
Yes! Thank you!
Lol man of culture
For what this video was it was highly entertaining. Love it
Thanks man!
That's a really entertaining video! Looking forward to watching the limit pushed further.
Glad you enjoyed it!
i love how the first version sounds like an F1 car revving it's engine XD
😎
1:25 KABOOM!
👌😂
usually, we use oil rather than water because water has a much higher surface tension on top of being more reactive with our traditional metal engine components, generating rust which weakens the components on top of their existing wear and tear
a "dry" counterpart is graphite
I will use Graphite next time...
I just discovered your channel from this, love what you do!
Thanks man!
Man you're creative as hell, You Earned A New Sub 🤩😁
Thanks, man. Really appreciate it!
@@LucasDynamics Ayy, Man you deserve more
For a future version, perhaps you can get metal technic axles so they don't wear out quite as much? Also, someone below mentioned using an "rpm reading thing" for better speed due to decreased load on the shaft... if you do this, I also recommend using a wheel with a marking on it instead of the spinning tooth thingy, to minimize vibration. I look forward to this series of competing engines :P
Yeah! I will use a laser measurement tool next time…
Why does the newer model sound like a McLaren
I don't know 😅
Fun project ! I really enjoyed watching this !
Glad you enjoyed it!
Amazing stuff, really cool mechanism 👏
Thanks mate!
A bit of silicone spray lube (jig-a-loo or similar) will save a lot of wear on your moving parts and likely help get higher rpm than water.
I think the style of his experiment is that he didn't use anything complicated, even manually timing the RPM only took a few more Legos instead of digital tools.
@@YolandaPlayneYeah correct!

A lot of comments debating the best lubricant to use on your Legos, but nobody has mentioned sewing machine oil. I think that would be a good choice.
Good point, but I think Graphite powder is even better...
I built this and decided to blok compressed air through it from the other side, and it exploded at about 15,000 rpm but sounded great before it exploded
Nice!
Sounds better than most of the cars nowadays.
Yeah😅
*4-rotor intensifies*
Congratulations 🎉🎉I'm so glad and proud of you!😊
Thank you!
I've learned so much in just few minutes, lol thanks

Just like regular shrapnel but ™

3:49 sounds like the FNAF 1 jumpscare
👌
I love the fact that you put “asmr” in the description 😂
The simplicity is pleasing
Yeah😎
I can smell burnt axles from here😂
Yeah😅
I built it and it's sooo powerful❤❤ Thank you for that amazing creation
You're welcome!
Offsetting the rod by half a plate upwards or downwards could increase the efficiency, as it can't spin with an extra full plate underneath, but likely could with half of one. Just leave a 5 plate tall 2 stud wide hole in the side and fill it with the inverted axle hole with a plate on top and tile on bottom. Use a bracket to hold the axle holder outside.
That's quite complicated 😅
Congratulations, you just made a supercharger.
Yes I did
It sounds like it too
Actually rotor vacuum engine with Supercharger
4:50 sounds like a Murcielago
😎
I have never seen more potentially dangerous lego in my life.
It was!
Back then I managed to put in ball bearings on the shaft to ensure less friction and a greater longevity of the axle and components whenever I build remote controlled cars. Even the originally supplied 9V motors were stripped of their sleeve bearings and equipped with tiny ball bearings I pulled from dead 40mm PC cooler fans.
Made a similar vacuum turbine that had triple the blade length and double the width, with an air inlet the same length as the turbine. Spun not as fast but that thing made a crazy amount of torque!
I was sure i read "4,74m subscribers" sadly an k and not an m, which you deserve. Im 100% sure you there in a couple years :)
That would be cool, but I'm on my way...

So, lemme get this straight: this guy built the WORLD'S FASTEST vacuum engine with LEGOS?
Yeah I did😎
It's fastest LEGO vacuum engine NOT world's fastest vacuum engine
@@user-jt999That's what the title says...
@@LucasDynamics yea but the other guy thought that you built fastest engine with Legos
Nice Record! Congratulation!
Thanks!
sounded like an f1 car at the start
Yeah, it does!
YOO THATS A SUPERCHARGEEEEEEEEEEEEEEEEEEEEEEEEER
Yeaaaaaaaaaah!
I wanted to see it without the vacuum,but u still put a lot of hard work into it
just subscribed! :) Love this channel.
This may defeat the idea of your designs... but can you implement bearings?
Thank you for subscribing!
I tested a few similar things...
Obviously it doesn't make boost but this is basically a vacuum driven roots style supercharger
I don't even have any Lego, but I watch these every time they show up
Because Lego is cool😎
What you did here is genius, so nice to watch an engineer using just legos to entertain us
Thanks mate!

Imagine if one of those lego inside it comes loose. It will get sucked up by the vacum and dissappear in to the oblivion😂
Nah, I would rescue it from the dust bag...
The start sounds like adults speaking in Charlie Brown movie
😅
For your future motors, I would recommend using wall pieces instead of bricks (or even having the wall pieces inside and the bricks outside for stability). This could result in less air escaping from the walls and lead to higher rotations.
Yeah good idea!
it sounds amazing! it would be awesome if you could get them hooked up in a way where it would have 4 of these like a 4 cylinder engine i wonder what that would sound like
With four vacuum engines?
@@LucasDynamics yes four of those connected with a single intake and a driveshaft so we can see how much power it's outputting or something like a combustion engine in a car? idk maybe it's a dumb idea but it might work
Actually the word record is 14000 rpm.
(By: Owen Vansanten)
I've seen lego vacuum piston engine. But lego vacuum rotary engine? Now that's something I wanna see.
I know, me too!
@@LucasDynamics Now I wanna hear it brap 🤣
This is a turbine though. Wouldn't make any sense to do a wenkel engine in Lego since there's no combustion going on.
@@wiegraf9009 I know, it's just how the air flows inside the engine that reminded me of a rotary engine. Aswell as the sound it makes, sounds like a 4-rotor.
@@dosh8276 yeah for sure!
you could also try accelerating the incoming air via a tube adapter that tapers into the intake (exhaust? idk, where you put the vacuum). make it as smooth as possible to achieve less turbulence, that might not end up doing much but could squeeze more efficiency out of it
Thanks for the ideas!
It's also possible to make use of the venturi effect, whereby a fluid accelerates when it passes through a narrower space!
love the video and also i’ve tried it before in the gaps between the corner of the rotor put some play doh to fill the gaps in created better suction
If you allow play dough, you might as well machine the chamber out of a solid block of plastic or, even better, aluminium.
Lego means lego, not lego plus play dough.
Yeah, I wanted it to be just out of Lego...
2:38 the vacum sound like its saying *ss
😎
@@LucasDynamics ?
im not sure how efficient a little vaccum powered engine on a gokart would be but i love that it sounds like an f1 and i wanna make one now
👌
I COME FOR the Lego sounds
😅
I've seen vacuum cleaner attachments that use a similar concept to drive rollers/brushes.
Had what looked like a radial fan attached to the brush via a belt.
If LEGO/Technics has something that looks like a radial fan, try that too.
I will!
What person did you beat?
Just look for one of the top comments...

No it sounds like a supercharger
Nah more like a tuned rotary engine@@hanselleonard7633
Can you add a multi-speed gearbox next one? I can imagine how cool it would sound!
Nice!!
Incorporate some ceramic ball bearing into that thing... it'll REALLY rip, then :)
edit: and the gear reduction timing mechanism really slows it down too, I bet

This is incredible!
Thanks man!
How does a fuckin lego engine sound better than most actual ones, fuck man. what a world we live in. btw nice build
😅
Going by general usage it's not an engine because it isn't converting chemical energy into mechanical energy. It's actually a turbine (turning linear mechanical energy in the air into rotational mechanical energy). Under some definitions you could call it a motor or a mechanism as well.
@@wiegraf9009But generally an engine is everything that converts power into rotary motion...
@@LucasDynamicsThere is no agreed upon universal definition of engine. If you look in dictionaries or encyclopedias you will get conflicting definitions. The point I was making is that IN GENERAL USE OF THE TERM an engine converts chemical energy into mechanical energy. If you look at specific technical definitions you will get conflicting ideas of what makes an engine an engine. In its first use the term referred to anything that was a product of ingenuity but we don't use the term that way anymore.
@@wiegraf9009 Yeah, turbine or motor are also correct...👍
Cool engine
Thanks bro!
Very cool, but what if you were to use _two_ vacuums?
I could try it, but that will definitely destroy the axles…
@@LucasDynamics Try using a steel axle.
@@zennzibl but he's building a vaccuum engine not an air blowing engine
@@zennzibl He doesn't care about your explanation...
He wants to make an fast lego engine with a vacuum on one side and atmospheric pressure on the other. That's the challenge. Meaning all you get is 1 bar of pressure difference. So the only way to get more speed is to optimize the build...
Of course you can get more power by blowing, but then there is no challenge. just put a jet engine on the other side and done... but that's not the point, facepalm..
I do care about his explanation! Because it's totally right what he says...
Sir said the right gear ratio for me to know I do not understand. Onky thing I would at the convention that year, "hunh, impressive."
