3D Printed CO2 Rockets with ONBOARD CAMERA!
Вставка
- Опубліковано 17 січ 2018
- In this video I attempt to install mini spy cameras inside of my homemade 3D printed CO2 rockets. These rockets snugly hold 12 gram CO2 cartridges that are normally used in airsoft and paintball guns. I also end up putting the cameras inside of some model rockets! If you haven't seen my previous video on these CO2 rockets make sure you go and watch that as well! The printed used in this video was the Creality CR-10.

Three ideas:
1: Shorter launch tube with larger diameter. Fins with larger diameter then the rocket, and the rocket stabilized in the tube like a SABOT style projectile. Se wikipedia.
2: More fins. A high number of small fins should increase the effective area causing drag. Having 12 fins should equal having 4 fins with 3 times the area, but the rocket body will be making a hole in the air, so the drag increase would be much less. More like 1,5 to 2 times that of having 4 fins.
3: To increase flight time/height; heat the CO2 cartridge to about 40 degrees before launch. Can be done by storing the rockets in a heating blanket before launch.
Please replay to the comment for more ideas.
a larger tube will lower the pressure inside,I think,the rocket needs to travel a longer distance in the tube,just like a rifle......
But the friction of the tube will also slow down the rocket. If you look at real concepts for rocket launches it is only at the start there is any real advantage to have it in a tube, and if the rocket is stable in construction (i.e. placement of center gravity and center pressure is correct) it doesn't need the tube to stabilize. This can bee seen in any full size rocket as well as in something as simple as water rockets.
One option could even be to fill the bottom of the tube with water to make a better seal against the rocket to increase the pressure right after the start. This has been proposed for many rocket systems like the Space X BFR, and is actively in use with submarine launches.
Another option can be to have a small water tank that the CO2 cartridge is connected to, so that for the first half meter of flight it is actually propelling it self on a stream of water. this would greatly increase the acceleration in the start, but would also make bursting the CO2 seal hard...
Another way to increase the area of the fins without making the rocket have a larger diameter would be to encapsulate them with a ring, like a duct on a propeller. This could connect to all four fins, and could even have a "ribbed" structure to pull even more air into it. All without increasing the total diameter of the rocket.
watch the vid of Richard hammond here on YT on propulsion threw a tube with an air compressor,the tighter the projectile in the tube the longer it goes when fired.
it's on RH connections with the building of the A3880.
I think the pvc pipe wobbling back a forth also has something to do with the rockets not flying straight :)
Its way late to comment, but its doesn't fly straight because its not balanced. If it was spin stabilized (rotate about the Z axis in flight) it would fly true
that wat i though so still looking at the wind and the weight it also a bit disadvantage as moving up to air the wind speed is increasing so that we dont have enough edge which can cut through it !!!!!!!!!!!!!!!!!!!!
(lets hope you got it)
me too i saw the guy's hand move forward a little when the black rocket end was in but the head was out
testtestjimmy if it was spin stabilized it would be useless for video
Tary1233 maybe a brass or metal pipe could do better
when you want a legit excuse to buy tiny cameras

From all that *sweet sweet* revenge of course >:D
The stability could be improved by stiffening you launch tube. As it is the rocket causes the barrel to whip around and will flick it off to the side. Three dowels taped around the perimeter would probably do the trick though more would be better.
Do you sell dowels for a living? I would use one.
@@no-name420 Walmart has them for cheap. Just make sure they are straight. Some are warped a bit.
very cool! I just got my pen cam in the mail. Not sure why I ordered it but this project gives me some ideas!

Space engineers: micro
Thank you for completing a satisfying video, despite all the setbacks!
Awesome!! Love that you are working the trial-and-error process and making improvements each time. For a more stable launch, try cutting 50cm off the launch tube. It appears that the PVC tube bends during launch causing friction to the rocket and an unstable trajectory upon launch? A shorter tube may correct that. Try different lengths. Keep up the great work, and I can't wait to see what you come up with next!!
Really nice work, man! And congratulations to the winners! Specially to Creating Creations! :D
MC's Creations Thanks:)
FYI spring loaded fins would work or a smaller rocket with a discarding sabot either of these would allow the rockets to fly straight. Also you should make a video about redesigning these rockets as torpedoes that would be awesome.
Simple stability testing: With everything loaded (engine and payload) make a loop on a string and put it around the rocket body. Move the loop until the rocket will balance horizontally, then tape the loop so it can't move. No you can spin the rocket around in a circle on the string, if the nose cone stays forward you have a stable design, if not you need bigger fins or more weight towards the nose. It's what the rocket does while in the air that matters most.
You can actually learn an amazing amount about rocket/fluid mechanics through tests like these
Thanks for the keychain.
Loved this video, and the co2 rockets in general. I do notice in the slow mo's that you get a bit of whip in the end of the launch tube...have you considered using Schedule-80 pipe (the black stuff), it's meant for high pressure, therefore much more rigid that then schedule 40 (white). Just a thought, keep up the great videos
I love brief construction montages. Bring it on!
Way cool! We built Co2 dragsters in high school for a wood shop / science project. 100' of deep sea fishing line taunt between two points and supped up pinewood derby cars with eyelets on the bottom. Same idea and it was loads of fun for a bunch of seventh graders. We had a few mishaps at the starting line but I still remember it like it was yesterday. Seen the description in the video title and had to take a look. Thanks for the video. Great job!
I feel like your launch tube thing needs to be more vertical, more stable, more rigid, for vertical and more lubricated
I would recomened peter stripols javlen roocket series to figue out foldable fins
randomness yay - same idea. But I had suggested to take the RPG-7 propelled grenade and make a less deadly copy :-) Foldable fins rock
The feeling when you cant find your model rocket...
Ive been there with my mini quads, I have already lost 3 and I have somehow lost my model airplane which shouldnt be too hard to find but its just gone.
This video is definetly worth a sub, your content is great
I avoid the 'losing' feeling by just gluing fins onto my rocket engines, and if I'm feeling real crafty I toss a nose cone on the engine.
I love it, Empirical design. Fast make / test / improve. ❤❤
Put a whistle on them now
hmm remembers me of 1942 no no Germany bomb …
Launch Co2 rocketa on summer time. It flies much faster.
heating up cylinder a bit might help without melting plastic.
seems like winter the air would be dryer with less water humidity, and therefor have less resistence, so rocket should fly higher
@@SystemsPlanet
Dry summer day should be best. The temperature of the air and the plastics on the rocket matters since the CO2 container itself will rapidly become colder due to the decompression.
your project just reminded me of the movie "October Sky". Enjoyed a lot. Thanks
Neat stuff! Years ago (read, "pre-digital"), Estes marketed the Cineroc. It was fitted with a miniature movie film camera. All cool and stuff, but I don't recall seeing any flight films, so I don't know how well it worked. Really enjoyed this one, thanks!
A bit late in coming, but as an alternate design suggestion, try making a CO2 spigot mortar.
For anyone who hasn't heard of a spigot mortar, look up the British WWII PIAT (stands for Projector, Infantry, Anti-Tank). The projectile goes over the firing tube, not inside, so you don't have to create such a small payload.
Cutest dog!!
Impressed with your dedication. You kept trying which finally paid off!
This is awesome! All that hard work, but you still had fun and enjoyed it even though there were many failures. Keep strong! Have fun :)
Creative idea well executed
Thank you!
you could make triple spring loaded fins on a hinge to make the rockets fly, it can probably fit, considering you can easily 3d print a small mechanism.
But they would scrape on the barrel
Fred Frod if you make a spring loaded set of fins that have a weak spring in it, then it won’t be a big difference compared to what occurred now. Only thing you have to do is making a pin that will lock the fins in place when it is fully extended. That way it has almost no drag, but it can extend those wings to a bigger size
The rocket itself already "scrapes" on the barrel. The added drag would be minimal.
Nice vid I have never seen a experiment like this I have wanted to make a CO2 rockets but I don't have the stuff to make it but awesome vid.!!!!
when I was a kid we had a similar rocket with a camera and parachute already built in. That was probably one of the coolest toys I ever got to play with or, more accurately, watch my older brother play with.
You should try putting a sabot on the rocket and launching it from a larger diameter tube. That way your fins can be significantly larger than the outer diameter of the rocket.
I have never built a rocket before. Just designed black powder rifles. lol
this
Lots of good solutions or suggestions in the comments.
It’s funny how people are idiots and usually this only gets worse as you get more people involved…and yet in the YT comments sections, which often the pinnacle of human stupidity and mob mentality run amok, and yet… and yet…
Just completely remove the pvc pipe and use a slightly modified(like a 1 inch hole drilled into the base of the launch pad where you put the nail spring thing) version if the estes model rocket launch pad.
P.s. 3d print a little tube to align the rocket with the launch pad.
I'm currently learning the art of 3D printing! So far, that's been a learning experience!
Nice work. Something I couldn't quite finish 40 yrs ago. Fuel was a problem then. Had to manufacture it from matchstick heads. Greetings from New Zealand 🇳🇿
Powdered zinc and sulfer we used to fire them in a homemade bazooka..used those Estes ignitor
Add folding fins to it, Like rocket grenades or anti tank rocket launcher head's have.
Launch tube is too long a wobbly. Stabilize the tube and set the launch like a mortar shell design fins so the fold around the fuselage. Once rocket eject from tube fins will fold out with help from rubber bands, tensioned bamboo, springs, or even air drag shape. Liked the ideas.
Awesome guys, love the style, looks such good fun
Take this as a compliment my friend, coming from a black man I must say in all my years it will never cease to amaze me the White , Anglo , Icelandic, Germanic, Celtic and related blood are the only ones who “invent”, “teach”, show tutorials, help others with ideas that further advance civilization as we know it. I am ashamed of my people as the videos they produce are selfishly based IE want to be rappers, dancers, entertainers, they want to make millions but they do not want to work for it or use their minds. Rapping and dancing and making world star videos laughing at drowning victims are not what I would consider conducive to the growth of the civilized world. Thank you for this very interesting video and continue using the gift God has blessed your people with, YOUR MIND!
I understand. Thanks, I get a lot of grief from liberals.. my apology
Could use something like a sabot for the fins and use a thicker tube
you rockets are really cool but now you need to build a sturdy launch pad and a more accurate pin for your puncture.
I love that you don't give up!
That is so cool.
I can think of a couple of fixes that would require varying levels of effort. The easiest way would be to not print the fins, and simply glue fletching to the side of the rocket then wrap it in wax paper to reduce the friction. Once the rocket exits the tube the fins will unfurl and the paper will just float off to the side. The other concept is to do away with the launch tube altogether, and design a launch mount with more standard model rocket features.
Cant you try making he fins spiral a little bit so its more accurate? Ofcourse thats not good with camera but it sure makes a beautiful launch :)
Came here to suggest that. NASA flies sounding rockets ("Super Loki") that spin to give them more stability.
But spin when you are trying to take video is generally a bad thing. Yes the rocket would be more stable in flight but the video would just be spinning round and round.
Very good. I like the CO2 cartidges. I did a series of youtubes back in 2012 that parallels your exploration rather closely. I used a compressed air cannon and like you added a camera and experimented with parachutes. When I stopped I was close to a design that would go straight up then fall backwards on it's tail so the video wouldn't flip upside down. During descent, the tail provided enough drag that I didn't need the parachute after all.
I really love your never give up attitude
Still better than anything North Korea has at the moment lol
Fordman 1991 incorrect but if it brings some people comfort then sure.
Nope. They actually launched a rocket that probably went further than any amateur builds.
/r/wooosh
The North Koreans might surprise you on their tech and ability to send a heavy missle. While your comment was funny,....way off the mark.
@@mihirpatil8843 their rockets are decently advanced but definitely not as good as any structured country like the USA.
All you need to do is increase the amount of drag on the bottom of the rocket. Try making a tower instead of using a tube, you can still use your current device to launch it just make it shorter with slots for the fins. If you have questions reply and I can help.
that phill bot the only issue I'd see with that is that the expanding gasses create pressure, which in turn gives the rocket thrust. But, like a bullet, this only works in a chamber like the tube. If he had a way to provide more propulsion than I think the slotted launcher would be a great idea
I think you're on the right track with the drag at the back. Perhaps extending the straight body of the rocket down over the aft taper a little to form a kind of skirt.
Hopefully YT won't mangle this ASCII-art...

Should let you keep diameter the same while adding some aerodynamic drag and allowing for the existing fins to stay.
The open slot in the bottom for the trigger negates that.
my science teacher while explaining jet propulsion did an experiment with a 38gm CO2 cartridge tied to a taught tensile wire stretched the length of the science lab, we ended up with a CO2 capsule with 30 feet of wire attached bouncing off walls and ceilings for two minutes as 30 kids lay under the lab tables hiding as they didn't want their arms and legs cut off or head decapitating, he did say he had never done this indoors before ! it was winter, maybe should have waited six months,
I launched many model rockets as a kid. The simpler the rocket the better and more stable they go. You could also go with multiple stage rockets. There used to be a model rocket called an egg launcher. It had a three engine cluster. Three size C-6-7 engines. The difficulty was getting all three engines fire at the same time. You could also buy a kit with an assortment of tubing, nose cones, balsa wood to create your own designs.
Use mouse traps for the spring pop out fins
North Korea missile testing
I use too fly model rockets when I was a kid, I use to test them for stabilization by tying a string around the CG point ans then spinning around
Wow! something I wanted to try for a while.
Some apple farmer is gunna be so confused.
try the cam on front of the rocket
The young Sheldon has grown and has become a rocket scientist. Who would think that! I´m glad!
I recommend using a sharpened drill bit to make the puncturing nail. Super durable and stays sharp longer than the nail.
You should make the fins riffled so it has a steady spin in order to fly straight high and stable
you want it to spin less. you won't get good videos if it's spinning a lot.
who gives a fuck about videos, if you can't even get your rocket stabilized?
Fins are designed to mage the rocket spin, not to get rid of the spin. Spin is a good thing for rockets and projectiles, that's why you have rifled barrel guns. Also that shitty camera won't make any good footage ever, there is no point of fucking up the whole rocket for it
Actually, fins are designed to stop it from spinning and to move its center of pressure behind its center of mass(especially with unguided rockets)
Fins create drag. Spin created by fins creates more drag.
@@MrDoboz the point of the video is too get good footage dickhead
Just got recommended this vid. You want good footage you should just drop the rocket idea and make a nice, slow hot air balloon with a 3d printed "basket" or do what everybody else does and use a drone. If you are going to stick with the rocket idea you need much larger fins and then design a different launcher. I did tons of this stuff when I was kid, usually through boy scouts. Ironically for your project the best flying rockets usually have the tail fins all ever so slightly pointed in one direction so the rocket flies with a spin like a bullet/football. Also consider a flasher and launching near dusk so you can find it afterwards.
The Co2 rockets launching reminds me of how a cruise missile looks when they first launch. They too, are a bit unstable until they get going. I used to really enjoy launching model rockets, but like you discovered, they’re easy to lose or even more frustrating to find them dangling in a tree and out of reach! Thanks for your efforts.
Michael Patterson hi
I am impressed.
Cut three slots in the pvc tube so longer fins could work
Alpha_wolf 1987 you wouldn't have as much pressure to the rocket
You wouldn't have much of a launch
So for the fins, why not have 4 fins that are spring loaded? When placing the rocket in the tube, manually press the fins in, and slide into the tube. Then, when it gets pierced and exits the tube, as soon as it exits, the fins will spring out and have more stable flight?
SilentAirGunner but it might slow it down
great footage on the black brant III
This hard work deserves at least 10M views
Put a Parachute on it
Simply cut lines in the tube and add bigger fins to fit between the lines :P
Mr. unitato the pvc would become too flimsy because it is so thin and long, the fins would catch against the inconsistent gradient of the cuts, the gradient being caused by warping in the pvc
P.A.N. what about a square tube?
I think a square tube with the fins aligned in the corners and a sabot would work well
Interesting idea thanks!
Use pen camera, USB is much lower quality, maybe try to make wings wider than rocket, like this air go next to them so they don't do anything... i think :)
Take some more rugged pipe and cut holes for wings to it, i noticed that on slow motion pipe is pretty soft and it bent on start.
Oh and mount cam on top, not on side, it will rotate much slower and image won't be so blurred
The USB cam is on a flexible cable ...you could poke it out the side and point it down to get a cool shot. Just print a nacelle on both sides to balance drag.
Cool projects!
I bought that same box set and lost in on the first launch as well. Lucky I bought two. Lost the second on first launch also. Now I’m on my fifth home made rocket. Like paper towel tubes and cardboard. You gave me some ideas including a camera. I bought some big D12-5 engines I’m currently construction a rocket for. Wish me luck.
when you have all the technology and none of the knowledge needed to build a rocket...
Please don't drill in objects you're holding in your hands. Younger viewers might get inspired.
Write your phone number on your rockets, that way, if it gets away from you, you might a phone call when someone else finds it.
lhl2500 So he can get sued for broken winshields and Windows?
Bruh...
Well, if he broke something, wouldn't it be right to actually pay for damages?
Don't give your 10yo a drill...
you didnt have a drill when you were 10?
Great attention to detail and explanation of everything! I love your video style!
I wonder if you could make design using some water that the co2 pushes out first to give it more thrust, I think. And maybe a small streamer on the end to help stabilize it.
I saw your video and tried some of my own rockets. I didn't think to capture footage, but I decided to use a shorter tube. MUCH shorter, but added extended fins to the rocket. The extended fins made it so I did not need the longer length of pipe. My total PVC pipe length is only 14". What I did at the top was cut channels 8" down into the pipe, like a cross [+] if looking down the pipe. The channels are about 1/4" wide. I made my rockets with fins that extended about 20mm from the body. The rocket stabilizes amazingly. I didn't do the camera mod, but did use about 1oz. of clay, as mock weight, and it worked quite well. I did a generic 35-degree angle on the fins, but I'm sure you can try any design, shape, or angle you feel is necessary. Only piece of recommendation is make sure you sand the channels in the PVC pipe, WELL, and maybe round the corners a little.
In Australia this is a firearm and you can go to jail for up to 14 years for making firearms. Our gun laws are just ridiculous.
Trudeau bans CO2 rockets ;)

if it hits a window or smthin or a person or idk then they will know who did it
Tokyodriftbabys
That wold be funny
That rocket had a parachute. It is unlikely that it would damage anything on landing. Even if they go ballistic, they are not capable of doing much damage. They just don't have the weight or energy to break glass. The only windows that would be at risk from a vertical launch would be windshields and they are extremely strong safety glass.
ah ok but it was just an idea
dstnlockwood
cool use of 3d printer
awesome video!!
If you want to add a parachute, you could just somehow attach it to the top of the rocket with some strings. Like that, when it's flying upwards, the parachute is being held down by the wind that is produced by the motion of the rocket. When it falls down though, the wind goes under the parachute and the rocket can get to the ground much more safely. I'm not 100% sure this'll work with a rocket as it might disturb the flight path, but we did a similar thing with a meteorological balloon, and it worked like a charm.
I admire your persistence. This is how America became great. Good work men. Failure is always an option....and a teacher.
Oh wow spinning so fast
Good for you for trying, trying again, and, trying once more!
EXCELLENT
Loved it!! Your a good kid...was funny....lol thumbs up brother.
A real life rocket scientist
Haven't touched my xyz printer in 3 years. Time to break it out again ! Great content
The last one is epic!
pop out fins sound amazing if you can do that. I would recommend making slits in the pvc along where the fins would go.
A couple of thoughts:
1)The Firing Pin. Have it secured in a bearing, much like a firearm does. The Hammer is spring loaded weight, not the firing pin. That way it strikes where it suppose to every time.
1a) Sharpen the tip of the nail with more insight. If the rocket fins deliver a rotation to the missile, cut the firing pin so that the escaping exhaust is channeled into a slight spiral towards the fin direction. However, any rotation won't make for a very good camera view, so bag the fin idea entirely, . .
2) And use the old fashion STICK method. Cut a thin groove along the launch tube for the balance stick to slide up when fired. The Stick shouldn't be heavy, for it only acts like a drag rudder. (Think "Bamboo". . ) If it were a hollow tube, it would be lighter and would work even better, being that it would act like a pseudo "fin" as well. . . But, it still needs to be long and ridged enough to stabilize the missile against the air flow to keep the pointy side up and the stinky side down..
Oh yeah. . . Reinforce the nose cone. In fact, make it a rounded blunt. Your rockets don't achieve super sonic speed, so in all reality, a pointed nose cone will induce more drag, where as the rounded aspect is the way air naturally flows traveling at a sub sonic speed. And always remember, the way it went up, will be same the way it comes back down. Pointy end first.
Problem solved?
I had this idea the other day, and I gotta say, great idea!
I still have a rocket kit that I bought back in the 80's that has a built-in film camera that takes a single shot after apogee when the nose cone is ejected for deploying the parachute. I used to get really cool pics of the area that I was launching from because the camera would be facing downward when the shutter was released. If you want to get some amazing footage with your setup, try installing your camera on an Estes rocket/glider or something similar. The rocket boost stage launches the vehicle, and then it glides down in an adjustable spiral. So you could video of the launch and then great video of the glide down.
Another cool video.
I enjoyed this. Great idea using co2. The pop out fins would be an interesting project. Thanks for sharing!
awsome bro try glueing on arrow fins or veins as they are bigger and also flexible so will go down the launch tube
For the co2 rocket extending fins, you could find small springs that may work in dollar store cap guns.
