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
Can we all take a minute to appreciate how well made that spot welder looks, despite the obvious home made nature of it. Maybe future video show how it's made! Edit: Do i have the most upvotes? P.S. I love tomatoes
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'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
Your spot welding technique is actually used in some pretty advanced aerospace applications. The centaur upper stage rocket is a "balloon" of ultra-thin stainless steel sheet metal (around 0.020") that's joined and sealed with tens of thousands of spot welds. It's so thin that it has to be pressurized or it'll collapse under its own weight, but it's the highest performing upper stage rocket in terms of mass fraction
you should make a turbojet engine or 3. i know you could manage based on your videos. quite fun, although the ones ive made were horribly out of balance. turns out micrograms are enough to blow up 1/4 in steel if you go above 90k rpm.
I think a video about you learning to weld better, so that your jet engines can fully shine inhouse would be awesome! The process of your learning and tips you pick up along the way would be amazing to see!
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.
@@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.
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.
I am a sheet metal worker and have used spot welders millions of times but never seen one made from pliers... my man ur a genius! with that said I have always been interested in attempting to build a model sized hybrid solid rocket engine / jet engine. I think this would be an awesome project for you to take on.
I think you should build a test stand ! It would allow you to actually put numbers on your engines. And depending on what you measure it could help you troubleshoot the engines. Interesting videos, keep it up !
Your dedication to your art of engineering goes above and beyond. When you want something, you learn about it and then learn how to do it. I know engineers who are not happy to teach beyond their grasp. Great work my friend!
Great Video! My suggestion is to build a testing rig for all your engines and see which one has the best thrust to weight ratio! Could be like a tournament between the types of engines.
I don't wear gloves either, LOL! Thank you. You inspire and educate this 32-year-old Music-Man tremendously. I wish I had come across your page waaaayyy sooner. Only advice I can give to you. 💯❤ DO NOT EVER STOP DOING WHAT YOU DO, BECAUSE WE NEED MORE PEOPLE LIKE YOU, SO THANK YOU!!!🏁
hi Integza, quick welding tip when you weld you want to heat up the area where you want the join to be. try putting the blowtorch a bit closer and then apply the material you can also then reheat the surface. This avoids potentially harmful dripping and discolouration of the metal. But so far you're doing great soo keep it up!
Video idea: I would love to see that pulse jet in flight! I don't know anything about 3d printing... but I think making a plane for the jet would be amazing to see!!
The pulse jet needs a lot more fuel, try turning the propane tank upside down to inject the liquid propane instead. Another thing you can do is to look into Lockwood pulse jet designs, they are said to be easier to start and also simpler in design.
I think it would be interesting to make some sort of engine powered directly by the output gases from water electrolysis. There are a lot of videos on how to do electrolysis but not much on what to do with it.
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?
I’m so envious at people who understand how the math side of these things work, I’m studying electro mechanical engineering next year and I’m bricking it for the algebra side of things. No matter the questions I ask chatgpt or the RUclips videos I watch, or the book I read, it just doesn’t sink in. It’s like I’m trying to speak Japanese without knowing how to.
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/
You should make a hall effect thruster by using a magnetic field to limit the electrons' axial motion and then use them to ionize propellant, efficiently accelerate the ions to produce thrust, and neutralize the ions in the plume.
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 have 2 ideas that you could try: 1st. Use BrownGas(HHO), it will be more powerful because it's already mixed with oxygen and it's has a quicker ignition time and fire propagation times. Instead of pure hydrogen, BrownGas is easier to make(12V 7A electrolysis) and more safer, because you can control the production debit by a potentiometer =)) 2nd.Also, to be sure that the jet engine has a proper cooling, why don't you make some fins on the body of the engine? You can use a simple fan or some water that is flowing over the body, in that way, you will solve the problem with "thermal isolation". The fins can be some metal strips welded on the body, you don't have to make it look fancy =))))
@@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 =))))
00:45 The vibrating water tube looks like an awesome engine idea. Simpler than a stirling. Just apply tidal engine to it. A floating magnet and a coil and it's done.
Oh nice I love this effect. It can also work in reverse allowing you to use a specific sized tube and its matching frequency of sound to create a heat pump. I'd love to see you try that out btw.
Hi Integza, love the material and ideas. Keep them coming! Apologies if you’ve done this already but I would love to see a practical demonstration of a rocket motor idea I was once told about. Essentially, it’s an integral hybrid fuel motor. The solid fuel component is a hydrocarbon. Typically heavy oil mixed with an epoxy resin. During preparation, this mixture is held in a cylinder, turning on a centrifugal turntable, turning at a modest but, appreciable r.p.m. The oxidiser component can be liquid oxygen or nitrous oxide and is injected from the bottom into to the liquid phase as it spins in its mould. The oxidiser often helps to activate the epoxy. Another initiator may also help. The end result is a honeycomb of oxidiser bubbles within a solid fuel matrix. The purpose of the spin is to form a density gradient of bubbles with more at the centre and fewer at the outside. This is supposed to aid initiation, and also to permit thinner walls in the reaction chamber is the solid fuel mass remains a structural component until the end of the burn them, I reducing rocket mass. I’ve only ever heard this talk of and have never seen it done. The strikes me as an excellent practical experiment for your channel.
Make a multi-stage rocket solid or liquid fuel, for the solid rockets adding aluminium powder to the resin should make if more efficient such as in solid rocket fuel
Integza, you should be given a medal or acknowledgement from NASA for single handedly inspiring a generation of Rocket Scientists to go out and change the world!
A suggestion for a future video: My pc fan recently broke down so I bought a new one, more powerful but also stupid loud. Since you're pretty good at building ionic thrusters, try building an ionic pc fan. I know it won't fit in the case, but at least it should be able to plug in the motherboard. I know you can do it!
A huge improvement to the 3d printed plastic version would be to fill the "walls" with water! Just imagine putting a bigger cylinder over it and filling the gap with water. Did you ever throw a water filled PET water bottle into fire? It doesnt melt, because the water cools the plastic better than the fire heats it. Same should work here too! I dare you to try it in a future video!
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.
Its been so cool watching you over the years making more and more complex rockets and other cool stuff! I would love to see if you could make some sort of RC car or boat with your engines. Keep up making awesome videos!
Integza thank you for delivering such top noch content. Jet engines have always been one of my favourite topics and like you i am also truly fascinated by the pulsejet due to its thrust to weight ratio, lightweight design but maybe most importantly the sheer simplicity of its design. "Where normal people only see some random pipes, i see a potential jet engine." Now for the main part: I have a suggestion for an experiment that you could try out with a pulsejet. I just happened to remember one of the Mythbusters episode where they tested out sewer explosions that caused manhole covers to be launched up in to the air due to ignition of built up methane gas. Now the most interesting part of this experiment is what happened when they loaded the "sewer system" with different types of debris that caused the explosion to accelerate at an extremely rapid pace compared to the "clean" sewer system (in the small scale sewer test that they performed i believe they tried filling it with metal springs/ coils of different sizes that would simulate objects that may somehow end up in the sewers like ex. bicycles, wheels, wooden planks and other random types of debris/objects). This made me wonder if this effect somehow could be exploited to increase the performance of a pulsejet by for example placing a metal coil(s)/ wire inside the combustion chamber or perhaps by partially or fully lining the combustion chamber with some kind of steel mesh. I think it would be really cool to see some experimentation using this effect/ principle and if you are able to make it work reliably maybe you could build a test rig and compare the performance of different fuel types like Propane(used as a referance fuel), Ethane, Methane, Hydrogen ++ and maybe even try some types of liquid fuel like different alcohols, heck maby even some Nitromethane. Just be careful when using liquid fuel as it can be hard to manage it in a pulsejet and can easily drip out of the pulsejet and set the ground/ surrounding on fire (In my teen years i once set my parents wooden terrace on fire while trying to start a pulsejet using a 50/50 mixture of alkylate petrol and nitromethanol(25% nitromethane IIRC), luckily for me my ADHD brain had developed enough sense in regard to safety to have the gardenhose laying ready in case this were to happen). As an additional note: Different fuels may operate optimally at different pulse frequencies, this probably also depends on related factors such as fuel pressure and injector design/ placement. To a degree you might be able to make a quickly tuneable adjustment system to the pulsejet by adding a telescopic section to the tailpipe as this can alter the "resonance/pulse" frequency it operates at (IRRC there is someone who have tried this and have a video(s) about it here on youtube). Best of luck with your future projects and experiments
I’ve been trying to get into 3D printing for a while yet can’t bc of price and your videos are really amazing to show what it can do. Also an idea for a next video could be trying to practically/semi-practically apply a jet you’ve made for something like a model plane or rocket
Fun Fact: the V-1's pulse jet created a steady 45Hz drone (smack dab between an F1 note and F#1 note on a midi keyboard for reference) that earned it the name "Buzz Bomb" by the british
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
Try optimizing the jam jar pulse jet engine (using something else than the jar), to get the longest run time and put it on a small boat or car and see how far it goes
Somewhere in the fields of thermodynamics, frequency modulation, and high energy sources lies the fundamentals to space travel. I've felt this in my bones since I was young. Something to do with the controlled resonance of metallic/ceramic materials and the resulting vibration interacting with the surrounding medium is fascinating to me.
yah, pressure mediation is also a key to everything. I think ufo's use implosive tech rather than explosive tech. Instead of kinetic expanding force and negative charge a craft that follows the principle of positive charge is the golden ticket. Think about an electron making its way to capacitance to a capacitor what is the force moving to capacitance? Dielectric acceleration
I would love to see a return to some old projects now that you can get certain metal parts 3D printed. Just being able to see what potential some of your old designs would have I think would be awesome.
Anyone else think it’d be a cool idea for Integza to put one of his engines in an RC plane or rocket? I’d pay good money to see him play Kerbal Space Program IRL.
You should try to design a 3d printed shaped explosive charge. A rocket is a controlled explosion, but so is a shaped charge. Would be awesome to see if it would be possible blow a hole through like 2 inches (5cm) of solid metal using 3d printing
@@Acrophobia2 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
Amazing video as always 💪. My suggestion would be to create a super conductive platform and then make a track of magnets on a loop and finally on top of the super conductive platform put an engine. It would be interesting to know how many RPM it could reach. Pd: sorry if I make any mistake making this comment but I'm not a native English speaker 😅
brother i bought a diesel heater for 130 bucks and i have been learning so much about them, the crazy thing is on the inside its similar to jet engine in someways like the burner and combustion chamber but it uses an electric motor to pull in air to the chamber anyway i think you should check them out or just buy the burner part and modify to an engine if possible.
Possible future video/implementation you could build a small thrust measuring setup, guided on air pressured rails (atmospheric railway), so the future jet engines can move with minimal traction. More air pressure could also support the weight of the whole system. The thrust could be measured by the sled pushing against an precision scale. This way you could directly record it for the your videos It would be really interesting to see and compare the thrust from different engines
The homemade spot welder is what impressed the heck out of me. I'm going to make one for myself. The engine is cool, too. Edit: Aw, heck. I thought that the spot welder was homemade. Oh, well. Cool spot welder adaptation.
Video idea: you should make a magnetohydrodynamic thruster powered boat. Or just try to make a well optimized MHD thruster that could be eventually used to power something. It seems like very few have attemped to make something like this on youtube and i would love to see you put your own spin on it. (Yes I liked my own comment)
i think you should consider making a jet engine using household materials -mostly- stage by stage and making it more complex every next engine. it would be awesome to people trying to get familiar with the working principle and the limits of the materials!
Hi, Integza! I follow each of your videos with great interest and appreciate the way you explain scientific and technical concepts. I have an idea for a future video: could you explore and explain the principles and applications of ion propulsion technology? It would be fascinating to see how this type of propulsion works and how it could be used in space exploration. Thank you and keep up the great work!
I think you should try liquid cooling for your engines. It sure takes a longer time to make, but the benefits could extend burn time to multiple minutes if not more. Maybe "weld" a long metal tube in a spiral pattern around the burn chamber, attach a pump and a coolant reservoir, make the pump move the liquid through the pipes into either a large coolant reservoir that would act as a heat bank or a radiator from a moped or pc or something. It sure would make an interesting video. You could also try adding some heatsinks to your engines to radiate just enough heat to stop the engine from melting. Remember to use thermal adhesive, thermal pads or thermal paste between any cooling element and the surface.
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.
Dude, you rock! I took a welding class a few years ago and I’m super impressed by your home brew spot welder. If it helps weldingtipsandtricks is super helpful.
I like the pulse jets, but I think one with some kind of cooling and/or throttling (to control both temperature and thrust) would be the next logical step.
Great video as always, Integza! As a video idea, I'd love to see this kind of engine on something which actually moves, then you could get into aerodynamics and all the other systems which go along with building an aircraft. It could just be like the example from WWII which you gave. You could even collab with Tom Stanton, as he has so much experience!
I think this idea is really nice, and I do get the point of reducing weight, but what about a cooling system? You'll probably be able to run the engine for longer periods of time, and maybe use other materials in order to build it.
Absolutely mind-blowing work on this 3D printed pulse jet engine! For your next video, I'd love to see an in-depth exploration of the practical applications of this technology. How could this engine be adapted for real-world uses? Perhaps you could delve into its potential in aviation, drone propulsion, or even power generation. It would be fascinating to see you take this groundbreaking innovation a step further by demonstrating its versatility and usability in various fields. Keep pushing the boundaries of what's possible! 🚀🔥
Pulse Jets have limited applications based on several factors from my understanding. In transportation for instance you wouldn't see a pulse jet car because of how loud they are, it would be a terrible ride quality and public nuisance. I am not 100% sure about aviation but I believe they don't have enough power to weight, or it was fuel economy that made pulse jets less attractive then the current standards. They are amazing, and their simplicity is probably their strongest point, I've wanted to try making one since I saw Colin Furze do it!
The practical application of a pulse jet is limited to hobby RC aviation almost exclusively. There is virtually no alternative use case. This is exceptionally old, completely tapped out tech. Even kamikaze drones are better served by more reliable and more available electric and two-stroke motors. Their use by Fieseler is entirely due to a complete lack of any practical alternative power sources at the time. Today, if we want a V-1 style cruise missile, there are very cheap, widely available disposable turbine engines that will perform far better and more reliably, and won't enable acoustic detection and tracking.
You really owe it to yourself to learn to weld. It's pretty easy and it makes all sorts of things possible. Your home made spot welder is amazing. 3-D metal printing to braze on is mind blowing for and old guy like me. My dad had a rig that would spray molten metal back in the 1970s. Wire feed withe oxy- axcetylene. He actually still has it, last time it was used I tried making a branding iron for furniture. Forty years ago. He got is surplus and used it to metalize art. Sprayed bronze into plaster molds, then washed away the plaster. Neat engine.
When I was young, back in the 60's, a mate of mine worked for a company that used metal sprayers for relining cylinder bores on engines, and rebuilding the big end and main bearing journals on engine crankshafts. I remember he even used an aluminium sprayer to make a 2 stroke piston back to its original size when it wore down on the skirt.
I recall being told the sprayed bronze could be made porous and could hold oil. One of the applications in industry was sintered bushings.I think it might be obsolete by modern standards, but it's a neat machine.My father used it to build some doors that were the entrance to the Playboy club in Chicago. When the place was closed Michael Jordon (basketball) bought the doors. As far as I know they are still in his house.@@BobHUK
Small pulse jet model airplane engines that ran on sterno pellets were sold in the 50s i still have one but no fuel. I'll have to look around to see if i can find it.
I would love to see an episode of a homemade fusion reactor. Even if it isn't efficient. A homemade particle accelerator would be fun too. I may be asking for too much. Just an idea
I wonder if you would consider creating a basic laser tripwire security system? This could be a very viable and interesting project for a maker. Especially if the core functionality is kept simple to start, with room for optional expansions later on. The process of designing, troubleshooting, and refining the system would also make for engaging video content. Making a custom enclosure that neatly houses all the electronics and laser pointers would add a complexity level to the structural design and fabrication, and including the ability to add features like a webcam, motion tracking, or remote monitoring/control would ramp up the complexity quite a bit.
Have you ever tried to do the same but using a sterline engine concept? You could try to use various modern day nethods and liquids to keep it running to cycle

hi Integza, quick welding tip when you weld you want to heat up the area where you want the join to be. try putting the blowtorch a bit closer and then apply the material you can also then reheat the surface. This avoids potentially harmful dripping and discolouration of the metal. But so far you're doing great soo keep it up!

Video idea: I would love to see that pulse jet in flight! I don't know anything about 3d printing... but I think making a plane for the jet would be amazing to see!!
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 pulse jet needs a lot more fuel, try turning the propane tank upside down to inject the liquid propane instead. Another thing you can do is to look into Lockwood pulse jet designs, they are said to be easier to start and also simpler in design.
I think it would be interesting to make some sort of engine powered directly by the output gases from water electrolysis. There are a lot of videos on how to do electrolysis but not much on what to do with it.
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 so envious at people who understand how the math side of these things work, I’m studying electro mechanical engineering next year and I’m bricking it for the algebra side of things. No matter the questions I ask chatgpt or the RUclips videos I watch, or the book I read, it just doesn’t sink in. It’s like I’m trying to speak Japanese without knowing how to.
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 ...":

You should make a hall effect thruster by using a magnetic field to limit the electrons' axial motion and then use them to ionize propellant, efficiently accelerate the ions to produce thrust, and neutralize the ions in the plume.
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…
You should try using electrolysis to make a hydrogen thruster! Love your content.
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!
That would not work. Even 3000 watts in a commercial HHO generator produces a tiny flame.
The world needs a lot more people like you
I have 2 ideas that you could try:
1st. Use BrownGas(HHO), it will be more powerful because it's already mixed with oxygen and it's has a quicker ignition time and fire propagation times. Instead of pure hydrogen, BrownGas is easier to make(12V 7A electrolysis) and more safer, because you can control the production debit by a potentiometer =))
2nd.Also, to be sure that the jet engine has a proper cooling, why don't you make some fins on the body of the engine? You can use a simple fan or some water that is flowing over the body, in that way, you will solve the problem with "thermal isolation". The fins can be some metal strips welded on the body, you don't have to make it look fancy =))))
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

The vibrating water tube looks like an awesome engine idea. Simpler than a stirling. Just apply tidal engine to it. A floating magnet and a coil and it's done.
Oh nice I love this effect. It can also work in reverse allowing you to use a specific sized tube and its matching frequency of sound to create a heat pump. I'd love to see you try that out btw.
Hi Integza, love the material and ideas. Keep them coming! Apologies if you’ve done this already but I would love to see a practical demonstration of a rocket motor idea I was once told about. Essentially, it’s an integral hybrid fuel motor. The solid fuel component is a hydrocarbon. Typically heavy oil mixed with an epoxy resin. During preparation, this mixture is held in a cylinder, turning on a centrifugal turntable, turning at a modest but, appreciable r.p.m. The oxidiser component can be liquid oxygen or nitrous oxide and is injected from the bottom into to the liquid phase as it spins in its mould. The oxidiser often helps to activate the epoxy. Another initiator may also help. The end result is a honeycomb of oxidiser bubbles within a solid fuel matrix. The purpose of the spin is to form a density gradient of bubbles with more at the centre and fewer at the outside. This is supposed to aid initiation, and also to permit thinner walls in the reaction chamber is the solid fuel mass remains a structural component until the end of the burn them, I reducing rocket mass. I’ve only ever heard this talk of and have never seen it done. The strikes me as an excellent practical experiment for your channel.
Make a multi-stage rocket solid or liquid fuel, for the solid rockets adding aluminium powder to the resin should make if more efficient such as in solid rocket fuel
I like this idea
Hi Integza, great to see you wearing hearing protection at 7:00 . However a small detail, it needs to be covering the ears for the full effect.
Integza, you should be given a medal or acknowledgement from NASA for single handedly inspiring a generation of Rocket Scientists to go out and change the world!
A suggestion for a future video: My pc fan recently broke down so I bought a new one, more powerful but also stupid loud. Since you're pretty good at building ionic thrusters, try building an ionic pc fan. I know it won't fit in the case, but at least it should be able to plug in the motherboard. I know you can do it!
That would be cool even if it isn't powered by the motherboard
A huge improvement to the 3d printed plastic version would be to fill the "walls" with water! Just imagine putting a bigger cylinder over it and filling the gap with water.
Did you ever throw a water filled PET water bottle into fire? It doesnt melt, because the water cools the plastic better than the fire heats it. Same should work here too! I dare you to try it in a future video!
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
Its been so cool watching you over the years making more and more complex rockets and other cool stuff! I would love to see if you could make some sort of RC car or boat with your engines. Keep up making awesome videos!
RC AIRPLANE!
Bro the work you put in your videos is legendary man good job 👍🏻
Hello @dbgodgaming653 congratulations
Measuring the thrust on a bunch of your old engines would be cool to see.
Integza thank you for delivering such top noch content. Jet engines have always been one of my favourite topics and like you i am also truly fascinated by the pulsejet due to its thrust to weight ratio, lightweight design but maybe most importantly the sheer simplicity of its design. "Where normal people only see some random pipes, i see a potential jet engine."
Now for the main part: I have a suggestion for an experiment that you could try out with a pulsejet. I just happened to remember one of the Mythbusters episode where they tested out sewer explosions that caused manhole covers to be launched up in to the air due to ignition of built up methane gas. Now the most interesting part of this experiment is what happened when they loaded the "sewer system" with different types of debris that caused the explosion to accelerate at an extremely rapid pace compared to the "clean" sewer system (in the small scale sewer test that they performed i believe they tried filling it with metal springs/ coils of different sizes that would simulate objects that may somehow end up in the sewers like ex. bicycles, wheels, wooden planks and other random types of debris/objects). This made me wonder if this effect somehow could be exploited to increase the performance of a pulsejet by for example placing a metal coil(s)/ wire inside the combustion chamber or perhaps by partially or fully lining the combustion chamber with some kind of steel mesh.
I think it would be really cool to see some experimentation using this effect/ principle and if you are able to make it work reliably maybe you could build a test rig and compare the performance of different fuel types like Propane(used as a referance fuel), Ethane, Methane, Hydrogen ++ and maybe even try some types of liquid fuel like different alcohols, heck maby even some Nitromethane. Just be careful when using liquid fuel as it can be hard to manage it in a pulsejet and can easily drip out of the pulsejet and set the ground/ surrounding on fire (In my teen years i once set my parents wooden terrace on fire while trying to start a pulsejet using a 50/50 mixture of alkylate petrol and nitromethanol(25% nitromethane IIRC), luckily for me my ADHD brain had developed enough sense in regard to safety to have the gardenhose laying ready in case this were to happen).
As an additional note: Different fuels may operate optimally at different pulse frequencies, this probably also depends on related factors such as fuel pressure and injector design/ placement. To a degree you might be able to make a quickly tuneable adjustment system to the pulsejet by adding a telescopic section to the tailpipe as this can alter the "resonance/pulse" frequency it operates at (IRRC there is someone who have tried this and have a video(s) about it here on youtube).
Best of luck with your future projects and experiments
I’ve been trying to get into 3D printing for a while yet can’t bc of price and your videos are really amazing to show what it can do. Also an idea for a next video could be trying to practically/semi-practically apply a jet you’ve made for something like a model plane or rocket
Fun Fact: the V-1's pulse jet created a steady 45Hz drone (smack dab between an F1 note and F#1 note on a midi keyboard for reference) that earned it the name "Buzz Bomb" by the british
And. . . Doodle bug.
would you be able to do a homemade telescope?
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

Try optimizing the jam jar pulse jet engine (using something else than the jar), to get the longest run time and put it on a small boat or car and see how far it goes
1:43 As a twelve year old kid, I made one of these in the kitchen. The lid blew off and spread burning fuel everywhere.😂
Somewhere in the fields of thermodynamics, frequency modulation, and high energy sources lies the fundamentals to space travel. I've felt this in my bones since I was young. Something to do with the controlled resonance of metallic/ceramic materials and the resulting vibration interacting with the surrounding medium is fascinating to me.
yah, pressure mediation is also a key to everything.
I think ufo's use implosive tech rather than explosive tech. Instead of kinetic expanding force and negative charge a craft that follows the principle of positive charge is the golden ticket.
Think about an electron making its way to capacitance to a capacitor what is the force moving to capacitance? Dielectric acceleration
I would love to see a return to some old projects now that you can get certain metal parts 3D printed. Just being able to see what potential some of your old designs would have I think would be awesome.
10:02 imedeatly thought about an aztec death whistle when i heard this

Anyone else think it’d be a cool idea for Integza to put one of his engines in an RC plane or rocket? I’d pay good money to see him play Kerbal Space Program IRL.
you do a great service to the aerospace community. Keep it up!!
You should try to design a 3d printed shaped explosive charge.
A rocket is a controlled explosion, but so is a shaped charge. Would be awesome to see if it would be possible blow a hole through like 2 inches (5cm) of solid metal using 3d printing

That is probably illegal😂
@@Acrophobia2 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

Hello @blackIce504 congratulations
Theme for next video: 3d printed airplane with Turbojet engine which could actually fly.
@Te.legra.m_me_Theintegza please let me know sir
Possible future video/implementation
you could build a small thrust measuring setup, guided on air pressured rails (atmospheric railway), so the future jet engines can move with minimal traction. More air pressure could also support the weight of the whole system. The thrust could be measured by the sled pushing against an precision scale. This way you could directly record it for the your videos
It would be really interesting to see and compare the thrust from different engines
That little pulse engine is brilliant! I’d love to see it fitted to a tether car and see how it goes compared to the little nitro two stroke engines.

Hello @bobjeaniejoey congratulations
Video idea: you should make a magnetohydrodynamic thruster powered boat. Or just try to make a well optimized MHD thruster that could be eventually used to power something.
It seems like very few have attemped to make something like this on youtube and i would love to see you put your own spin on it.
(Yes I liked my own comment)
Magnetohydrodynamic drives suck... you need passive amounts of power

Is it just me, that it actually sounded like an aztec whistle. Anyway it was a cool project Integza, i hope yo see more about jet engines.
i think you should consider making a jet engine using household materials -mostly- stage by stage and making it more complex every next engine. it would be awesome to people trying to get familiar with the working principle and the limits of the materials!

Build a ram jet or turbo jet engine and compare the amount of thrust to the pulse jet engine..
0:10 Nope, Integza, that is a crack pipe… 🌡️ 🔥😂
I think you should try liquid cooling for your engines. It sure takes a longer time to make, but the benefits could extend burn time to multiple minutes if not more. Maybe "weld" a long metal tube in a spiral pattern around the burn chamber, attach a pump and a coolant reservoir, make the pump move the liquid through the pipes into either a large coolant reservoir that would act as a heat bank or a radiator from a moped or pc or something. It sure would make an interesting video. You could also try adding some heatsinks to your engines to radiate just enough heat to stop the engine from melting. Remember to use thermal adhesive, thermal pads or thermal paste between any cooling element and the surface.
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.
Correct me if I'm wrong, but doesn't the fuel line allow the high temperatures to decompose the propane into better fuel types
Dude, you rock! I took a welding class a few years ago and I’m super impressed by your home brew spot welder. If it helps weldingtipsandtricks is super helpful.
I like the pulse jets, but I think one with some kind of cooling and/or throttling (to control both temperature and thrust) would be the next logical step.
EFI is making this relatively easy now days.
Theres a rocket man doing go carts etc with propane....
Put the truster on a helium balloon, also again a very good video keep it up!

Great video as always, Integza! As a video idea, I'd love to see this kind of engine on something which actually moves, then you could get into aerodynamics and all the other systems which go along with building an aircraft. It could just be like the example from WWII which you gave. You could even collab with Tom Stanton, as he has so much experience!

I think this idea is really nice, and I do get the point of reducing weight, but what about a cooling system? You'll probably be able to run the engine for longer periods of time, and maybe use other materials in order to build it.
u could make an aeroplane with a homemade jet engine
i have a very interesting idea for you... build a rocket dyno: something with springs and markers to show how much thrust you actually produce
Absolutely mind-blowing work on this 3D printed pulse jet engine! For your next video, I'd love to see an in-depth exploration of the practical applications of this technology. How could this engine be adapted for real-world uses? Perhaps you could delve into its potential in aviation, drone propulsion, or even power generation. It would be fascinating to see you take this groundbreaking innovation a step further by demonstrating its versatility and usability in various fields. Keep pushing the boundaries of what's possible! 🚀🔥
Pulse Jets have limited applications based on several factors from my understanding. In transportation for instance you wouldn't see a pulse jet car because of how loud they are, it would be a terrible ride quality and public nuisance. I am not 100% sure about aviation but I believe they don't have enough power to weight, or it was fuel economy that made pulse jets less attractive then the current standards.
They are amazing, and their simplicity is probably their strongest point, I've wanted to try making one since I saw Colin Furze do it!
The practical application of a pulse jet is limited to hobby RC aviation almost exclusively. There is virtually no alternative use case. This is exceptionally old, completely tapped out tech. Even kamikaze drones are better served by more reliable and more available electric and two-stroke motors. Their use by Fieseler is entirely due to a complete lack of any practical alternative power sources at the time. Today, if we want a V-1 style cruise missile, there are very cheap, widely available disposable turbine engines that will perform far better and more reliably, and won't enable acoustic detection and tracking.
A practical application for pulse jets? Try asking the Germans
can you make a jet engine hovercraft that can float both land and water

You really owe it to yourself to learn to weld. It's pretty easy and it makes all sorts of things possible. Your home made spot welder is amazing. 3-D metal printing to braze on is mind blowing for and old guy like me. My dad had a rig that would spray molten metal back in the 1970s. Wire feed withe oxy- axcetylene. He actually still has it, last time it was used I tried making a branding iron for furniture. Forty years ago. He got is surplus and used it to metalize art. Sprayed bronze into plaster molds, then washed away the plaster. Neat engine.
When I was young, back in the 60's, a mate of mine worked for a company that used metal sprayers for relining cylinder bores on engines, and rebuilding the big end and main bearing journals on engine crankshafts. I remember he even used an aluminium sprayer to make a 2 stroke piston back to its original size when it wore down on the skirt.
I recall being told the sprayed bronze could be made porous and could hold oil. One of the applications in industry was sintered bushings.I think it might be obsolete by modern standards, but it's a neat machine.My father used it to build some doors that were the entrance to the Playboy club in Chicago. When the place was closed Michael Jordon (basketball) bought the doors. As far as I know they are still in his house.@@BobHUK

I would love to see an episode of a homemade fusion reactor. Even if it isn't efficient. A homemade particle accelerator would be fun too. I may be asking for too much. Just an idea
I wonder if you would consider creating a basic laser tripwire security system? This could be a very viable and interesting project for a maker. Especially if the core functionality is kept simple to start, with room for optional expansions later on. The process of designing, troubleshooting, and refining the system would also make for engaging video content. Making a custom enclosure that neatly houses all the electronics and laser pointers would add a complexity level to the structural design and fabrication, and including the ability to add features like a webcam, motion tracking, or remote monitoring/control would ramp up the complexity quite a bit.
Sounds like you need to post!!
I would love to see a jet-tipped rotor blade using several of those little pulse-jets! I imagine it would sound terrifying!! 😂
