Fastest 12,000 RPM Lego Vacuum Engine | World record!!!

[@nk54woibu40]

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.

[@rctv9974]

Silicone lubricant is far better for lego

[@LucasDynamics]

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...

[@jonathanroell8342]

What about graphite from a pencil? I’ve seen other people use it as a lubricant before

[@LucasDynamics]

@@jonathanroell8342 Good idea! Thanks!

[@lord_scrubington]

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

[@SpeedyySlugz]

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

[@LucasDynamics]

Yeah, without it, it would be definitely faster!

[@ccoder4953]

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.

[@Google_Corporation]

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.

[@Ghorda9]

@@LucasDynamics just use an IR laser to detect the revolutions.

[@taylorquimby4004]

​@@Ghorda9Bingo! I was thinking a hall effect but your idea would be 🤏 that much more accurate. 😁👍

[@Ranstone]

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?

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

[@joshmarchant604]

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.

[@YolandaPlayne]

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.

[@LucasDynamics]

​@@YolandaPlayneYeah correct!

[@AHSEN.]

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

It's a three stroke rotor engine First stroke: vacuum goes from the vacuum cleaner into the rotor chamber and the rotor starts to rotate Second stroke: vacuum in the rotor turns into air Third stroke: the rotary engine spits out air from its chamber and so on in a cycle BUT if we install a spark plug, then the 3-stroke engine will become a 4-stroke (at first glance) and the spark plug simply will not ignite the vacuum mixture
