You should make an Integza Nerf Gun. Powered by rockets or something and probably illegal in many parts of the world.

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

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 RU-vid 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.

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.

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

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!

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.

I have been wanting to get into 3d printing for a while, this channel has inspired a new hobby lol

I think you should try a peroxide rocket thruster! The thrust can be quite amazing! Edit. I mean using itself as thrust by decomposing with catalyst. You can get very high pressure whith it! Edit2. It is a different mechanism!

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!!

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

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.

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 !

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.

Man, I was literally just watching the latest video from Stuff Made Here, and he bought a super powerful and cool water jet cutter. It would be really awesome if you could do a collaboration! Love both of you guys, you both really inspire me in my engineering career 💪

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!

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.

would you be able to do a homemade telescope?

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.

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

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.

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 =))))

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!!!🏁

You should try out a arcjet engine! I haven't seen a proper one on youtube and it woud be awesome!!!

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.

Wish I had a science teacher back in my day that held my attention the way you do🤔. Great job brother

I would like you to reattempt the first jet engine you ever tried to create with all the knowledge you have learned over the years

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

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.

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!

Theme for a future video: build a microwave electrothermal thruster (MET). Basically, use the magnetron from a microwave oven to heat water vapor within a resonant cavity into a plasma, then accelerate the plasma using an electric field and eject it through a nozzle. This is one of the newer technologies being used for space tugs.

10:02 imedeatly thought about an aztec death whistle when i heard this

You should try using electrolysis to make a hydrogen thruster! Love your content.

Amazing. The part with the fireplace silicon and carbon mesh was very clever, even if it wasn't the final solution.

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.

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!

you should make an cannon that shoots tomatoes using hydrogen explosion pressure 😃

this is also one of the things that causes the guns to have such a loud sound it's not the bullet breaking the sound barrier it's actually the hot gases hitting the amblant temperature that causes that loud cracking banging noise

I love your enthusiasm. Just a small correction, the V1 rocket of WW2 was propelled by steam from a chemical reaction.

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!

Build a ram jet or turbo jet engine and compare the amount of thrust to the pulse jet engine..

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.

An idea for a video: Build a 3D printed sterling Engine and try to extract the most power possible from it

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!

Please build the " THUNDERSTORM GENERATOR " for internal combustion engines using water as anatomic fuel invented by Malcolm Bendall

he pathologically turns every engineering project into an arts and crafts project

10:05 screaming like Murph in home alone😂

When it’s does in a lab it’s called science but when it’s done in a garage it’s called a felony

Measuring the thrust on a bunch of your old engines would be cool to see.

A fun theme would be taking this really awesome engineering and fabrication for a super complicated Rube Goldberg to make like tea

That spot welding is amazing I bet you could make a turbojet with that. Also you could use brass pipes to make a radiator

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

You should make an MHD thruster

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.

Another thing you can do is to print the parts in plastic and then metalize them by electric arc spray. Then you remove the plastic by melting it like the old lost wax method for moles.

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.

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

I suddenly became obsessed with the science of propulsion now💀💀💀

for your next attempt at it, you could try to pre-cool the fuel before sending it into the line (the way you have it wrapped around it like that) to help the material not overheat. My concern would be the fuel line itself could fail and cause a dangerous situation while giving an added advantage of keeping the 3d printed metal from possibly failing as well. since it requires a temp difference though you may have to split the line before it wraps around it so that way you could wrap both sides before rejoining it at the injection point. this way you can cool both sides while still getting the temp difference.

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.

Here's an idea for ya! I think 3D-Printing a pulse jet rocket and mounting it on a flywheel/Alternator assembly might just grab the attention of StyroPyro, AND ElectroBOOM both! I think a colab with all three of yall would be amazing.

Great! There's a fascination to making big stuff tiny and working like the big ones! Would have loved to see the thrust it produces.

6:50 Who else is just sitting here & waiting for the stuff at the wall to start melting?.... :/ Really smart to start a "flame thrower" inside.

Theme for next video: 3d printed airplane with Turbojet engine which could actually fly.

Video idea: Alot of people watching don't have acces to the kind of amazing tech you have so I thought it would be amazing to see a video of you making something without any 3D printers and CNC machines. Like many engineers like Tesla would have had to prototype.

3D print a Nixi tube clock housing that allows for the tubes but also a Tesla coil on either end so you get a cool electric field above the tubes. Always wanted to build one.

You should strap that jet engine to an RC plane! I'm working on one myself (electric). That homemade spot welder looks awesome! I would really like to make one myself. I also like how he says every time, “Remember, tomatoes are disgusting!” I love your videos! I can't wait for the next one!

I made a waste oil heater for my garage that functions like a pulse jet. It resonates at 48hz, so it's a little more like the hum of a subwoofer. It's gotten me through a few winters so far and can run steadily on as little as 24 ounces per hour.

A video on the rotating detonation engine, the most powerful type of rocket, with comparison to a normal one and a jet engine in flight will be your best video Love your videos

Somebody give this man a large cnc shop already!

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

Hey Joel! You should make an Electrostatic Piston Engine. Allow me to explain. Basically, if you have two metal plates charged at the same polarity, they will repel. If they have different and opposite polarities, they will attract. What if you made the Piston of your engine negatively charged, and there were plates on the bottom and top of the whole cylinder which would switch polarity? You could repel and attract the piston in a reciprocating motion, thus causing a crank to move, and rotary motion.

10:02 - That 1 guy in a game on the mic

Could you put a pulse jet engine on a RC jet? To see if you could create enough thrust for it to fly? I feel like that would be very cool.

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

if you put it into a small water tank you can create steam for additional thrust. It is going to raise the efficiency very much.

you were my inspiration to sturt studying mechanical engeneering

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)

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

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.

A few unrelated questions: i) Have you ever read those tiny little instructions that came on soldering paste cans? Is a good way to start improving welding skills. ii) Why always the combustion chamber is done in metal when it smelt with high temperature? You could try plaster like in videos for making homemade iron-melting ovens. iii) Have you ever tried barbequed tomatoes? with cheese on top they are great

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 😅

As always great video! Love seeing your takes on these integral engine designs. Perhaps you could try and combine the designs of your best engines to make a super engine? Kind of like the SR-71 turbo-ramjet.

Major Payne elived his PTSD as a train just from the sound of the last one alone.

Your neighbors must hate you....but remember, we love the crazy stuff you do!

Chemistry background here...For the question on why propane burns better than butane...this is my take. E=1/2 mV2. Ambient thermal energy being the same for both (same E), but different masses, their velocity has to be different. Propane would always be travelling faster which then probably means mass transfer limit rate of burning is higher than butane.

you should make somthing with a 3D printed roman steam engine (Aeolipile). i belive that this will be interesting to try getting the engine working without it meltin gbut also being light weight enough to spin at high speeds.

I would have liked to see how well a ceramic printed pulse jet engine performed.

Video idea: Put a Ducted Fan (Edf) on top of a foam board boat and try to get as fast as possible.

Integza will build a spaceship when he finaly gets his own metal printer

Imagine what could be done when integza gets a metal 3d printer! 💪🤘😤

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.

Actual rocket combustion chambers have air/oxy entry ports all around the outside of fuel/oxy entry area. It keeps the outer shell cooler w a buffer of cooler oxy while fuel burns mostly inbetween the center fuel stream and oxy layer where it mixes.

Dude, the amount of amazing stuff you build, with the jankiest materials available is impressive. You need a real shop with real tools so you can use metal. If you had the tools to work with metal, you would be unstoppable.

BUILD A PULSE JET QUAD UFO!!! Single or quad engine, would love to see if it can float. Thanks, buddy!!!

Video idea: use one of your rocket engines and put it in an actual rocket, but with a tomato underneath the rocket as it launches.

Fill your tubes with water, cap them with wax and freeze the tubes, the ice acts as a mandrel allowing a tight radius without crushing it .

Theres a rocket man doing go carts etc with propane....
