Yes
Yes
OR make it from TOMATOES.
😊😊😊😊😊
that would be cool
Sounds like interesting idea
Clearly just needs more power. Soda stream canister rocket next pls! 😍
Hi me first
I like your style Angus!
Sounds like a myth buster episode
@@integza you were losing a lot of power using the rubberband. the way it is bouncing around and not sticking to the axil. also recommend making the exhaust of the little vehicle point to the rear so you can use the rest of the power loss to help propel the car.
Is a regulator or gears would also reduce the waste.
Hey, some suggestions, use a small gear coming off the wankle's axle and a larger gear on the wheel's axel would be a better transfer of power. Also the exhaust from the motor could be redirected to help push the RC car. Also, reducing the the diameter of the pipe before the CO2 goes into the motor will let the motor run longer and put less stress on it
Yes, you are a man of energy conservation as well, I'm seeing a lot of wasted energy in this video. I mean yeah great work but it's not performing at its most potential.
+Wankel engine leaks
It is honestly cringe having this machinery , and end up not doing these optimizations
Also there are things called pressure regulators, purely mechanical, probably would be the easiest way of limiting the gas flow😁
Ooh maybe integza could try to make a pressure regulator himself, its basically just a spring that presses against the incoming gas - and a screw that squeezes the spring more firmly against the oncoming flow, thus making it adjustable - OH or he could try something whacky but fun and make a governor, used in steam engines - as a person who works with modern automation ive always been fascinated by governors
Video idea . You should design a wankel rotary engine powered tomato smasher. Tomatoes are disgusting 😉
this would be a super funny video would love to see 🤣🤣
i also hate tomatoes so smashing them would be awesome!!!!!!
this is great!! 👍👍 have fun with that 3d printer!
unfortunately a rotary probably wouldn't have the torque for that, nevermind a reverse rotary powered by air
@@THESLlCK I agree, however, I would like to see some sort of tomato smasher even if it can't be wankel powered!
As a paintballer, I have an expansion chamber on my gun to give the co2 room to defrost and a needle valve regulator to control the pressure. So that I don't dump all my gas in one shot.
Agreed, should stop the engine destroying itself every 5 minutes aswell
That's what I've been thinking the whole time- he needs a way to control the flow rather than just dumping it all out at once. Expansion chamber and regulator set up is a must, and a gear-reduction unit for the actual drive from the engine to the wheels.
This project has great potential, just needs a bit more development...
Maybe a spool valve with a LPR to regulate/expand the CO2 to a gas. Add a point to the rotor to trigger the solenoid at the correct time. Maybe even some logic with the deadtime of the solenoid and everything like a ECU would handle.
I think the CO 2 cartridge you are using is enough power. What I think you need after the valve is a pressure regulator. The pressure regulator will allow you to throttle the engine, And allow you to preserve psi while cruising but alow For higher psi out put, for climbing hills.
integza: "I'm not made of gold!"
also integza: "I will give out a free 3D printer every video!"
Well decent 3d printers have become very affordable.
@@theq4602 ye but still, he could easily reuse any expensive parts he buys
And may I add, at a much lower cost than constantly giving away even the cheapest of 3d printers
He gets the printers from sponserships
If he does get them from sponsorships that does make sense
Also using an expansion chamber to let the liquid form to a gas fully before being expelled will help a lot with efficiency. Having the cartridge pointing downwards as you have it empties all of the liquid before it has a chance to turn into a usable gas
i am the 69th liked person!!!!!
I work on twostrokes and was about to say this
Or orient the cartridge with the outlet up.
You’ve got to turn the cartridge spout side up so that you get gas out instead of pressurized liquid CO2
Ding ding ding
Actually pressurized liquid can be better... maybe?... Just think about water rockets. They are more powerful than compressed air rockets.
@@potatosalad68 Sadly not. This works for rockets since increasing the mass of the exhaust gives more thrust, but here we don't care about the thrust produced by the exhaust and we're basically wasting liquid gas that would otherwise decompress still in the cartridge and give more power.
@@DeuxisWasTaken Oh, I meant it for the modified rocket car version, when he unplugged the wankel motor.
Also a pressure regulator or at least a decompression/expension chamber would go a long way for the wankel motor I think
It looks like there was so much slipping between the crank pulley and the drive pulley 99% of the energy never made it to the wheels. Yes, reduction gearing would help, but so would belt tension.
Add an idler pulley to increase the drive efficiency of transfer energy, also combine it with a stiffer rubber band
Or make a chain and gears instead of a pulley which relies on friction
Build a helicopter blade system with variable angle of attack mechanism
I don't understand half of what that means but it sounds cool
@@zen6591 he asks integza to build a propeller with a rod which changes the pitch of the blades when pushed/pulled
You mean a swash plate helicopter pitch control
That sounds like normal helicopter collective
@@benaguilar1787 tbf, has anyone on youtube made a thorough explanation vid with a diy conventional helicopter?
Also, seal the engine a bit better, and use a pressure regulator so you don’t waste so much CO2 making it more efficient (and not detonating the gears in the engine)
With a pressure regulator you’ll be able to run the larger CO2 canisters without worrying about the pressure blowing up the engine
And it can limit the torque to a usable level.
Rather than just spinning the pulley on the engine.
a better wheel and belt could be in order as the wheels and belt where slipping a lot.
Maybe increase the size of the pulley for the wheels as well
@@FicusThreeSixty a balancing weight for the rotor wouldn't go amis either, that would help the bouncing belt and wheel a lot.
When the valve open and the contraption flew out… Jarvis set the power at 2% moment 🤣
I appreciate when youtubers genuinely want to support their sponsors and don't pretend to play raid all day.
You need a pressure regulator so you can have a constant pressure to the engine.
Also to keep the CO2 from coming out too fast which clogs it with liquid CO2
Yes, exactly! That was what i was screaming at the screen while watching this. Most of the fuel is lost just getting the car rolling. A pressure regulator and a gear box with a high and low gear sets would have worked great here. Low gear and low pressure to get the car moving, then shift to high gear while it's moving and open the valve for some happy fun times!
Or a govener that is able to keep the engine at constand RPM
and better transfer from the Wankel to the wheels.
3DPrintedLife designed a pressure regulator that you can use.
Aside from needing a regulator to lower the output pressure, you also need to make sure that the neck of the cartridge is facing upwards. The cartridges are filled with liquid CO2, so you are expelling the liquid and not the gas. Turning them upright will give you more thrust and better control.
And maybe heat up the cartridge? Releasing the CO2 may cool down the cartridge so much that the CO2 remains liquid at ambient pressure? Or maybe not, these cartridges are fairly small ...
@@michaelseitz8938 the faster the gas is released, the colder the cartridge becomes, and the lower the internal pressure becomes. However, that is not entirely what causes a pressure drop. It takes time for the liquid to turn into gas, which is usually the most significant reason for the pressure drop. When you use a regulator, you extend the length of time that it takes for the cylinder to evacuate, which in turn gives the liquid more time to turn into a gas. Heating the cylinder will help the reaction somewhat, but typically not by enough to make a difference. If you're looking for a 5-10% difference, then heating the cartridge might be what you need. Good thought though!
yes "inetzga" can't seem to understand the wasted energy of liquid co2 coming out of the exhaust port
he even knows liquid propane makes more flames than gas if he flips the bottle so why is he no noticing the same flaw in reverse with the co2 cartridges?
@@michaelseitz8938 nope 90% of performance issues is just the fact he has the pop side down rather than up while in a gravity field with a critical gas canister
flip it and he'd get more stable and longer running 800psi flow with less issue caused by rapid loss of liquid co2 mass
sure mild warming if he intends on using 800psi for very long might be needed in smaller cans but at about the 88-90g cans the depressurization of his projects at max flow won't be enough to chill anything bigger than a 16g can enough to lose performance
plus he seemingly can get lots of propane which is a nice source of a stable phase change 150psi source so he could use propane bottles to run "pneumatic" engines on the go with much cheaper valves plus the flames from the exhaust ignited by "integzabot" would be a nice cosmetic touch
Video Idea: It will be interesting to print and made a hairdryer with a self sustain engine
If there was some sort of gearing that could make the valve open when rpms are low and close when high, you could make it so the engine keeps the co2 coming out just enough to run the vehicle. Thus the engine would modulate throttle for best efficiency.
I think that even just changing the thin rubber band for something like a gt2 belt would massively improve the performance. And also if you would use some kind of pressure regulation, spreading the CO2 discharge over a longer period of time (just a small hole the gas has to go through could be enough), it would also help
I second the pressure regulation. The co2 cartridge is super high pressure and most of that is going to waste out the exhaust. Using something simple like a capillary tube (I think) could help regulate the pressure leaving the cartridge, meaning that the engine can convert more of the pressure to rotation.
i agree. He should 3d print a belt using bendy filament and make a belt pulley system. The engine has a lot of power bu the power is being lost due to the rubber band slipping out
It just needs a receiver of 2x the size of the bottle
Good idea's the max pressure without leaks should be tested, this is than the max regulated pressure
Yes, it looks like the rubber band belt is slipping.
idea: reduce vibrations on the engine by having a second "layer" where the triangle rotor is out of phase with the main one
That’s called a two rotor engine, it’s what most rotary cars use for that same purpose. More power too :)
The vibrations are caused by the slipping rubber
Next next video: I 3d printed my own 4 rotor RX7
A 2 rotor engine with the rotors at 180 degrees from each other.
Wait… what? Every production RX-7 I know of was a twin-rotor. There were three-rotor engines built for the Eunos Cosmo… and I suppose now with a bit more Googling, it seems like a few people have done a motor swap to put three-rotor engines into some RX-7s.
But in this specific scenario, I don’t really see how using more rotors would solve any problems. Integza wasn’t facing any issues with vibrations really, but rather faced issues with the fact that the wankel rotor-by design-rotates three times as fast as the drive shaft. Multiple rotors help in increasing available horsepower/torque to the drive shaft at more and more offset intervals, but this often comes at the cost of much more complicated eccentric shaft designs (in order to enable assembly), while the rotational design itself already reduces vibrations significantly just from not being a reciprocating action.
Adding more rotors to a compressed-air wankel probably also wouldn’t really make any sense, as it would just increase the static volume of the system and thus decrease the pressure of the system as a whole leading to less power… and as mentioned, still doesn’t solve the design principle that a Wankel rotor rotates at a speed 3 times that of the drive shaft.
Dude I found this channel last night and in less than 24 hrs I’ve learned more about stuff I’ve wanted to try than any other channel 👍
Love that your engine even blows up like the real thing
You're using co2 wrong.
Instead of feeding liquid gas that expands inside you have to let it expand before feeding velocity based engine. You may try redoing it with proper atomization onto heat radiator to speed up evaporation, or use it with more traditional piston engine which performance should be good on lower rpm with proper dozing.
For the evaporation on liquid co2 i know there was airsoft gbb with very small gas useage that used cylindrical mesh which dispensed aerosolized liquid co2 inside small metal chamber before feeding. There was practically no visible fog coming out of it with preserved bb velocity compared to other types, and significantly reduced gas useage.
You can basically apply similar rule to combustion engine... trying to add too much fuel will choke it and supress it's performance, or even cease it's operation.
Basically do not try to hit highest rpm in first try, but make it work, then improve. I really want to see it explo...
Eghem... work.
And tomatoes are great!
you are extremely accusatory, i hope elementary school gets better
@@lord_toker I just pointed out the problem using strong introduction in first sentence. Due to not having english as primary language and writing without spell checker there may show up few typos. If whole thing seems accusatory it wasn't intended after first sentence ended, then i may have failed to write it in correct style, probably due to differences in comunication between different cultures and languages, while trying to keep my suggestion as short and informative as it's possible.
did not ask
@@lord_toker you just mad cuz this guy is smarter than you. maybe dont make fun of him for not speaking english well. so not only is he smarter than you, he probably knows more languages than you. you need to go back to kindergarten to figure out that people are more than twice as smart as you and that you need to actually live a life instead of making fun of someone for one mistake.
@@DeTNTonator Personally I found it all pretty interesting. Also what's the gbb airsoft gun/system called?
Always a good day when Integza uploads
Exactly
You´re right!
indeed.
I printed this motor up and ran it and I’d suggest using just a drop of air tool oil in it. Doing so made it run so much smoother than with just graphite alone. I supplied it with 125psi off my shop compressor and the bypass tube on the side blew out. If you can add a bit more thickness in that spot I think it would handle it. It also has a balance issue that could be remedied with a flywheel. I would lengthen the shaft and have it protrude both ends of the engine and put a balancing wheel on the back and a drive gear on the output. All in all its a pretty good start.
Integza you live in Portugal? Wow.... So Proud. I thought you were living in east Europe or Russia.
Very good to know that we have in Portugal guys that are ingenious making videos like yours.
You should try restricting the flow from the CO2 cartridge to see how far you can make it go!
You need to turn the CO2 cartridge right side up, so that the outlet is at the top of the cartridge. The reason you're getting "snow" is that the liquid CO2 in the cartridge is being allowed out the bottom, instead of requiring it to boil, and releasing gas out of the top. You will get MUCH longer run times, if you do this. Adding a regulator would help, too.
No completely correct, dry ice is sublimated from the drop in vapor pressure.
Though he can GREATLY increase the eff by adding heat on the secondary (ie loop) side of the pneumatic motor.
The expansion of gas by a heat exchanger can be seen in early steam engine designs.
Wonder if he's considered moving a liquid on the secondary side.
Gravity may help reduce the sublimation, yet it's decompressing too fast.
@@cheerdiver not quite accurate. The co2 is stored in the cartridge, under pressure, in liquid form. When the liquid is dumped out the bottom, it is no longer pressurized to the point that it can remain liquid. As the liquid instantly boils, the temperature drops low enough that SOME of the liquid solidifies, leaving "snow" of dry ice. This solid co2 doesn't contribute anything to the production of power. If the gas is taken off the top, then the solidification takes place inside the cartridge, and as heat is absorbed into the cartridge, the solid will sublimate, leading to continued gas production.
@@JohnDoe-fk6id not quite accurate. pee is stored in the balls.
@@riccardomarcenta Not sure what you're smoking, but it must be good.
@@JohnDoe-fk6id Could he be mocking you, b/c he's aware of Boyle's Law, and vapor, pressure, density, Tri-points?
At ambient temp, CO2 is a gas OR a solid. Liquid CO2 requires pressure, AND appropriate temp.
To raise the question, shows you want to learn. If you want to go to the moon, research Black Body in Space, or you're going to freeze to death.
Seeing you hold it in slow motion made me wonder just how much energy the engine throws away via vibration/ oscillation. That explains allot as to the wear and tear these things go through in cars. I'm sure the problem is mitigated by having multiple engines in line with staggered positions, but this makes me curious as to how well a modern Tesla turbine might compete with one of these.
Integza, for the wheels, possible stronger rubber bands, or a tensioner pulley, and possible switch the drive to a rear wheel setup. (You could switch your intake and exhaust port connections around)
Having a slow controlled valve, releasing the pressure gradually and having longer operational time would be great, also if you also point the wankel exhaust behind the car it’d improve the efficiency because that pressure from top adds huge pressure on chasis and unnecessary friction.
he also could print a few more chamber getting more power (making a bigger car, adding a trailor for additional weight??),and the fuel would be spread instead of going only to rpm. Also on other channels I saw that it makes the motor more calm, because vibrations compensate each other. Also I think from turbo freaks to add an expansion chamber (actually it is not liquid CO2, but solid), could be usefull to get more use from the fuel
@@ricardojahns4348 another great idea 👍🏻👍🏻
Friction is part of it, but additionally it looks like there's so much flex in the axle/chassis that the periodic jet from the engine is causing it to bounce and lose traction and the rubber band is too flexible for the amount of energy being transferred, so a ton of the energy is getting lost to wheels spinning in the air, rubber band flex, etc. I definitely think a slower, more controlled gas release would go a long way to solving the issues. It would give it a longer operational time, but it would also help bring the forces down to tolerances that the materials involved could actually handle.
Toothed belts to prevent drivetrain slip, tighter tolerances in the rotor and better seals on the apices of the rotor would greatly increases the torque and decreases blow-by in the engine. Add in some lubricant to fully seal the engine and he may have something a bit better for the application.
Not only that, but it looked like the belt going from the engine to the axel was slipping a lot, so printing a toothed belt or a chain would prevent that from happening as well
Show the tomatoes who’s in charge by making a 3D printed biogas generator, powered by tomatoes
I imagine straw from the previous season's tomato plants is reasonably priced...
The tomato lord will be begging for his men back
Be sure to add fart noises as the final insult while you burn their corpses!!!!
Wow great idea!!! 💡
If you used a gearbox or a chain drive you could get a lot more power. The rubber band is slipping off the axle. 3D printed gearbox would be a neat addition to this.
Definitely needs some structural stability, some silicon sealant in any seams of the engine, maybe also add a mini regulator for the valve too so you can control its output force.
It obviously is just proof of concept but I feel like it’s such a beautiful and crazy design that should have a true representation of its ability. Even if it has a lot of vibration that mostly cannot be controlled, and a shape that is otherwise not that efficient on its own.
"When you can't buy, you do DIY."
Smort.
You called it DIY I call that jugaad 😅😜
We all learned this from greatscott
Smort like a certain shark.
Video idea: So as you have a lot of empty cardridges now... Maybe it is time to make molds and cast something using steel from cardridges?
I think it's safe to say..............that jump made Bo and Luke Duke quite envoius!! Do it 'gain there cletus!!
for the throttle you can regulate the air that comes out of the exhaust, by doing it that way you always have full power but the engine spins slower.
I would love to see some kind of pressure buffer that would allow the pressure in the canister to be used more gradually rather than in one big burst.
When you're driving a car, you don't dump the whole gas tank in the engine, you pump it in little by little.
🍅🍅🍅Video idea: Tomatoes contain a small amount of sulfur. You should crush loads of tomatoes and extract the sulfer, with the sulfur create your very own solid rocket fuel so you can make an tomato "powered" rocket.🍅🍅🍅
That would be an intrusting idea, but I'm not entirely sure Integza could do it. Cody from Cody's lab probably could do it though.
Or make coal with the tomatoes
Brilliant
For the diy valve you could have used a rc car servo but you managed to diy a servo itself so even more impressive!
Very cool idea. As a further project, I personally would try to install the engine in a rear engine layout and do so flat on its "face". You would conical gears to transfer the power to the wheels (which may be not a good idea considering the engine goes from 0 to full power in milliseconds), but it would theoretically be an improvement over the belt, and by not having the vehicle wobble up and down due to the rotor, the traction would be much better.
Video idea: 3D printed energy storages (mechanical batteries) - like winding springs, flywheels or pressure tanks.
Flywheels! Please, yes, Flywheels! 🐝⚙
Video Idea: You should make a 3D printed rocket with 3D printed rocket engines and a parachute so when the rocket lands you can swap the engines and send it off again, you could also use a tomato as a pilot!
I think Tom Stanton did something like that. But I'd like to see Integza's version...
Terran 1 intensifies
@@scottbruner9987 Yeah Integza version would be cool, as Tom's rocket didn't get very high I think it would go way higher and faster if Integza did it.
@@alt8791 Terran 1s' multi-million reorientation mechanism has nothing on a nylon parachute.
You can keep the engine sideways so that the exhaust pressure could produce some thrust force by pushing co2 backside
Some grip upgrades to belt and wheels will make a perfect rotary beast.
New video idea:
New specialization for integza: build a brushed electric dc motor! It's easy, just coils and brushes! You could 3D print some parts and use tin cans and aluminum foil for others!
Otherwise you could build a Campini jet engine, which has a compressor driven by a endothermic motor, like the wankel engine!
Video idea!! 👆🏼
Hahahaha :D
You've got your CO2 cartridge upside-down - so the liquid escapes it which drasticly decreases the effectiveness of the affair! Try to reverse it)
In the slow mo you can see the rubber band is jumping so you will need a less stretchy band to give it more power and more distance
the only youtuber i watch the sponsored ads of fkin love you integza
You should add some kind of manually operated regulator to keep a steady pressure - should put less wear on the engine, and give you more run time (even though it limits the top speed)
Also a stiffer frame (supporting the end of the output shaft) would mean better power transmission
Could have just said the degree of limitation upon the valve opening should work as a regulator without having to take the money for a real regulator. Correct me if im wrong but a valve half open releases half the air flow as compared to a fully opened valve.
@@benjaminsteakley you're kinda right but pressure is increased at the outlet of the half open valve. However overall flow is decreased, which is the fix this needs to run more than 3 seconds
(Video Idea) You've 3d printed engines, rockets, impellers, Turbochargers... The list goes on. Isn't the next step to 3d print a gun (and then use it to shoot tomatoes)? You could try to create Nikola Tesla's 'death ray', called Teleforce, but that would be a bit ambitious... Instead, it could be a BB gun, powered by springs, CO2 cartridges or even compressed air stored in a similar way to your Tesla Turbine boat video (just in containers that can hold more pressure). Alternatively, it could be a coil gun or you could try and harness the explosions that happened with the vortex rocket engine v3.
To the best of my knowledge, no one has ever made a working teleforce - ambitious is an understatement. But at least the tomatoes wouldn't see it coming!
there's a hell of a lot of slip in that rubber band you can see on the high speed. needs gears or a chain and sprocket system for more efficient power transfer.
You actually can 3D print a whole drone, as it's potentially a cheaper (and quick) solution compared to buying the skeletal frame and casing for the DIY quadcopter to name one - some are ridiculously expensive. So 3D printer is obviously the answer for certain quadcopter builds. Not to mention the advantage of optimizing the center of gravity related to the weight of the avionics put onto the drone frame, ensuring it do its job well in the sky without falling straight down.
video idea: use a tomato as battery with a lime battery kit and make a car powered by a tomato .Tip: Use capacitors to manage the in rush current of the motor
Ahhhhhhhhh😭😭😭😭😭😭😭😭 I lost the giveaway
Video Idea: Try to make a 3D Printed Chainsaw that can DESTROY AT LEAST 3 Tomatoes. Maybe with the "Wankel Rotary Engine" and some Co2 or Compressed air.
I have one of those CO2 bicycle pump things that has a lever that you press to inflate the tire. It also screws down to the valve stem. That might make this kind of remote activation thing easier.
I think maybe using a proportional RC car setup to be able to open and close the valve slowly, could be very interesting!
Turbo fan engine for the next video !
4:18 My inner tomato lord said that device would fly straight for Integza, he was very pleased!
Don't know why I've never seen this channel till this week. Subscribed a mad genius with a portrait of tesla on the wall, love it !!!
You need to seal that case up a little better, and add a spring tensioner. Awesome build!
Video Suggestion: Since you've already built a lot of rocket engines, how about you finally 3d print a rocket? Also launch it with tomatoes on board.
Build a Campini engine! It's a jet engine with the compressor driven by a piston motor! You could try it with w Wankel motor!
You could do so much more with this. You are dumping liquid co2 into the engine. You could probably run 2 motors with that much flow. Also if you used your metal 3d printing you could make a conductive pipe with fins to maximize the change of liquid to gass. The connection between the motor and wheels looms to be slipping, and as you mentioned better contact from wheels to ground would help a tone as well. I would bet you could get it to go more than 3 times faster and farther.
I love this channel! I hope to give some good idea(s) for one of your future projects.
The fact that your head was popped up over the table and the rocket car still almost took your head off, proves you need safety squints 🤣
Video idea: Power that Wankel-engine with something flammable so it looks even cooler so it shoots flames ;)
Then the engine has to be 3d printed in ceramic resin, otherwise the engine melt, but since ceramic is quite heavy, it can made from metal.

You should set this engine up with gear ratios. Also your rubber band was slipping too from the high RPM. I really wanna see a more realistic model car with this specific engine set up, it seems to have so much promise, and looks like such a fun project, as there are so many applications for a motor of any kind, and this one seems extra fun since you can see inside of it!

You should’ve shot the exhaust from the engine horizontally behind the car so that the escaping exhaust also pushes it forward. It was shooting upward which was pushing the car harder to the ground.
Amazing video as always I always love your videos
Theme for a video: make a pulsating rocket engine and maybe put it on a small metal car?
For someone that hates tomato’s you buy an awful lot of them!
Amazing, love your channel, gonna get myself a resin printer (hopefully mars2pro or the mars4k) soon (when my wife allows it) and then I am gonna try my luck on the Wankel-gear-transmitted-big-rubber-wheeled-CO2-RC-car
I love your style
This is my Mazda RX-7's favorite episode of yours, Integza! 😁
video idea: keep using the cardridges, but make a turbo behind to create even more power!
Video Idea: You should redesign the rotary engine you have there and make a multi-rotor engine! Much more challenging and much more power!
I think the car could work with some slight upgrades. Set the gas canister upright and add an expansion chamber so you dont have liquid/solid co2 in the engine. Fix the leaks. And fix the drive belt (rubberband) slipping.
Dude makes hundreds of rockets, with every engine imaginable, for literally YEARS.... but somehow never learned to anchor the engine in a static test.
Absolutely unbelievable, I literally fell off my chair laughing at this.
Video idea: Make a pc watercooler that pumps water with the Wankelmotor!
Please do some metal 3D printing projects! There are FDM filaments you can print that are 80% steel and 20% plastic. You can put it in a kiln and the plastic burns away, and it sinters into fully metal parts. Check out Ultrafuse stainless steel 316L for example.
To make a shot at your thruster engine idea from previous videos try using nitrous as fuel they make 20g nitrous cartridges which could easily be balanced with a compressed air cartridge!
Maybe what you're missing is a pressure reducing regulator for the CO2 bulb outlet?
Then you could set a lower output pressure, that won't hammer your engine to death and also give you a longer run-time.
You should try to incorporate some 3D printed compliant mechanisms in your next project!
video suggestion: you should make a air-powered phone charger with some kind of air-powered generator.
Video Idea: Come up with a relatively inexpensive to make Air Conditioner that's 3D Printed. It's hot here and I don't like being hot.
Your video's are amazing and a lot of fun.
Thank you!
Next time, do it with:
- drag tires (can be bought for pretty cheap for RC cars)
- chain/belt instead of rubber band (so much slipping lol) like they use on motorcycles
or just tie the axle to the engine's rotor... I think that'll break whatever plastic you'll use, but might try it :D
Video idea: 3D print a press for crushing tomatoes, and use a transmision powered with the Wankel engine. Using that high RPM you could create a good torque.
Video idea: Scale up the engine and try to print the rotary engine out of the ceramic resin to run it with fuel.
