Can you make pulse jet engine? (Valved version)

Pin this before it gets lost😂

I have been requesting the same video for years. Tesla turbine vacuum pump. NOBODY has measurements of the ultimate vacuum you can reach with them and it is one of the main use cases listed in the patent. PLEASE do this. If you can reach 1x10-6 it would advance the DIY semiconductor hobby by leaps and bounds.

@integza. Put a water cooling system on the tiny pulses get so that you can get the most trust out of it.let me know how it goes..or LIQUID NITROGEN COOLING RUN IT TIL THE WHEELS FALL OFF

Yep

Did u win

He already has

Wow so many likes thank you guys!

He already did

Nothing like some fine microwave repurposing.

It is cool but inexpensive, mini cordless spot welders, that are highly capable, are available over the internet, so I’m not sure why anyone would bother building their own, unless they maybe needed something highly specialized.

I think he made it 1 or 2 videos ago

I'm convinced that he will end up learning how to weld and 3d print and physics and get a PhD and whatnot - before he builds a working engine with homemade stuff

@@Yadobler I just wanna see him use a rocket to actually push/lift something

Even if he learned a very specific type of welding and for a specific material and just used that type of metal etc. That would be really easy on him then. All the speeds, feeds, amps, and instructions are already out there on the interwebs.

more like this video is about how to not weld better

@@TrashcanScienceStuff you have added something, yet taken away more. Typical mohamed mindlessness. I’ve seen pigs on a farm smarter than anyone I’ve ever met with that in their name.

plenty of learn to weld videos online I don't think the world needs another upload on someone learning welding

11:01 is his learning curve.

If you're aiming to launch normal darts (standard .50 cal) then there is nothing that hasn't been done i think the highest muzzle velocity is 400+fps for a "regular blaster" and backyard scientist and ididathing have broken the sound barrier with a dart.

So, 3d printed gun.

Its an full auto nerf gun using the exhaust of a pulsejet to propel its darts

@@barnabasrsnags4828 probably wouldn't beat Gatlingtommy's moab

This comment is a scam, anyways you'll probably get the 3D printer from integza

Integza: Tomatoes are disgusting. Also Integza: This Moroccan style tomato-based sauce is pretty good.

@@FLPhotoCatcher only because its the blood of his enemies

Hey it's the cryocooler guy

Tell. Me. More. That. Was. Cool.

He already built one, he used linear rails from a 3d printer to do so.

That's impossible when your jet engines last .5 seconds before melting.

​@@HideYaWife69eh, even a half second burn is enough to get TWR

haha true@@HideYaWife69

electrolysis consumes the materials used, uses a lot of power to generate relatively little amount of gas, and the mixture is more an explosive than a fuel; so I ask what's the "interesting" part of carrying water, batteries, to produce so little thrust with a happy explosiveness twist to it? It'd just be a gas-fired engine, HO or HHO gas, it's not "electrolysis powered", like why.

If you put a very fine screen vertically between your electrodes and make sure they always stay submerged, the gas bubbles won't flow thru it as they rise vertically. Then you have pure H2 and O2. This is much more useful as you can recombine them in a controlled manner, instead of a difficult to handle explosive mixture. Also the ideal voltage is about 1.5V for maximum efficiency. It shifts a bit based on pressure and temperature, but that is more complex than most hobbies are going to take into account. Using a higher voltage produces more gas, but heats up the water. So it is less efficient. The electrodes need to be as close together as you can make them while still having a separation screen. To lower the resistance and increase the current, which results in higher gas output. Also adding KOH to the water lowers the resistance dramatically and increases output.

@@dimitar4y No need to small brain everything in your life. The output gases don't need to go into an engine. It could just be a novel way to get the gases relatively safely. Like for example a mobile balloon filling machine that you charge at home, take to park and fill baggies or balloons with the hydrogen and cool. To make it more entertaining, could make them blow up in the air after a small delay. Now that's a new years special episode.

@dimitar4y For the fun of it. Why not? I never said it's useful. I personally know how inefficient it is. Why do people try to prove they "know more" than someone else in this ridiculous of a context. I find it interesting because I do. Why does there have to be a reason for finding a challenge interesting?

Where do you think he got all that hydrogen?

I'm not sure if the lenses or mirrors can be homemade and work well enough

The important question is what's your budget... If you just wanna see the moon and planets .. even saturns rings , you can make one for pretty cheap , I made one for about 25 usd

​@@zakirsheikh4209any link for that?

That would be pretty impossible without expensive technology

Booring.

good idea

yea

Imagine the potential of combining two powerful techniques: electroplating and 3D printing. By utilizing electroplating, But let's not stop there. Have you ever considered the synergy of two different engine types working together? Envision a Rotary (Wankel) Engine serving as the powerhouse to drive a pulse engine. Such a combination could unlock unprecedented efficiencies and capacities in the realm of engineering and innovation. Let's explore the possibilities!

I like this idea

you must see 3blue1brown series on basic algebra and calculus, is a masterpiece it should be mandatory in engineering classes

Keep at it. It's normal to be frustrated initially when trying to learn something new. Little by little things will fall into place, especially if you keep at it. Find a handful of approachable concepts, master these, and then slowly add new ones. If you dive in and expect to absorb everything at once, you will be lost. If you stick with it, you will get there.

Unfortunately that’s the teaching method at the uni I’m going to. Every day we learn a new piece of math equation. I had to postpone last year because it was all getting too much and I also had some health concerns but I kept on with it throughout. I understand some and others are like aaaaaaaagh. Derivatives and integrals are my main frustration but I’m hopefully going to get an appointment with the uni soon before I return in September to discuss some options.

@@daveysmith3944 One method that worked for me, is to print out on A4 sheets of paper, then post them up in your room using Blu Tack to avoid damaging the surface of the walls. On each sheet of paper print a set of derivatives and their solutions on one line for each derivative, and each sheet of paper should contain a set of related derivatives. Do the same with different sheets of A4 paper, with integrals and their solution;. For derivatives and integrals try to fit each one on a single line. This way your brain will subconsciously register them when you spend time in your room, and when you wake up each morning. Fitting each derivative and integral on a single line where feasible, helps the brain to better focus on each one. Buy a pocket sized notebook and hand write the same information on each page, as the A4 sheets, so when you're out and about, if you're waiting in traffic, or a bus or train and are bored, open the book at a random page and glance at one page then the other in a relaxed frame of mind, don't try to read and think about the derivatives and integrals. When looking at the A4 sheets in your room, don't try to read and think about the derivatives and integrals, just glance at them in a relaxed frame of mind also. In addition to derivatives and integrals, also print out A4 sheets and hand write in the pocket book, trigonometric and logarithmic mathematical relations. You may prefer to hand write on one page of the pocket book a set of derivatives and the facing page relevant trigonometric or logarithmic equations. If it helps, write the equations in terms of Electrical/Electronic/Mechanical parameters. To improve memory and brain function, another tactic that helped me was to take natural Lecithin supplements tablets: www.ncbi.nlm.nih.gov/pmc/articles/PMC4882550/ When I attended University, there wasn't easily accessible information available about taking wild fish oil supplements; had I known I would've also taken them at the time. Although I did start taking them after I graduated from University with my Electrical/Electronics Engineering degree: "... Ingestion of omega-3 fatty acids increases learning, memory, cognitive well-being, and blood flow in the brain. Omega-3 treatments are advantageous, well-tolerated, and risk-free ...": www.ncbi.nlm.nih.gov/pmc/articles/PMC9641984/

But hall thrusters only work in vacccum not in earths atmosphere

The atmospheric version of that is the ion thruster.

@@brktegebrehiwat5699 The atmosphere does not prevent them from working it just makes the thing they are pushing slow down too much

He could do it in a vacuum chamber…

THAT WOULD BE AWESOME

@@evy_leevy I would love to see thrust readings and all...but I would much rather see them actually flying! That would be so outstanding, imho!

Hey Integza, talk to RC Test Flight!

The tomatoes will become salad from hydrogen explosion

i just want to know why this man hates tomatoes 😂

I can't imagine farmer's reaction 🤣

he should use oxygen mixed with hydrogen

😮

he doesn't have explisive so I don't think it would be possible.

That is probably illegal😂

@@Pman353 Probably not, here in Sweden it’s illegal to even ignite a model rocket or a firework with more than 100 g of propellant. I don’t know what the laws are in other parts of the world, but obviously not as strict as in Sweden

@@hampusmollgard4954 it’s illegal in the US so I’m gonna assume it’s illegal in Portugal as well

That's illegal in the most of EU

That would be cool even if it isn't powered by the motherboard

Are you TRYING to get him assassinated by the C.I.A?

this vid has given me many ideas about using my sheetmetal expierence to build a rocket🚀

But isn’t there a risk that the engine might explode when he decides to ignite it, since there is already HHO in there?

It's a good idea, the browngas is too ez to made,lol

@@xmysef4920 nope, I test a thing like this( I made a torch for melting and welding), and I have 2 control systems: the power from the PSU and the gas valve + if it's backfire the HHO, it will burn just what you produce, not an entire tank full of gas at 4 PSI =))))

Good ides, i up this

daddy uwu

Until the water evaporates.

And explodes and throws super heated water and steam everywhere

Haha very very bad idea, as stated below there are 2 options 1. You make a vent and it eveporates 2. You don't make a vent and it explodes In both cases the water won't do much if anything, because it is spread thinner than in a bottle, and will heat up faster. A PET bottle will usually melt before it explodes, and the fire will make microscopic holes that relieve preassure.

add 2 ports intake and outlet and water cool it with a pump and radiator

@@kubik7203 that would make it way to heavy and complicated

​​@@Te.legra.m_me_Theintegza please let me know sir

It's a scam don't click it

​@@iBele.what

What​@@iBele.

I think he deleted the comment but there was a scammer under your comment

@@iBele. oh ok

Could you link a video which you used as a template?

@@Boz1211111 it's an original. If you're on Facebook, I shared a couple of videos in a group called Waste Oil Burners. That's the only place I've made it public though.

That's kind of what's happening with that coil of fuel line around the combustion chamber, but I agree, a dedicated water line would help get some life out of these little engines.

Just put a tube over the tube that makes up the engine and pump water through the gap between them, much simpler to produce and just requires a couple of large washer like plates to seal it each end and a small in and out hole for circulating coolant

why not having that modeled in the file and printed in metal, pipes around the engine for liquid nitrogen, i think a rocket engine is far more efficient at heat dissipation since the combustion occurs outside the engine body.

RC AIRPLANE!

EFI is making this relatively easy now days.
