GoPro Shot from a CANNON 

Nice work, boys! Keep it up! #GoPro

cool idea... now phase 2, make it whistle and the deploy a parachute at max altitude. ;~D

Your barrel is not smooth , therefore it will never land in the same place as before because it is unpredictable , you guys should print out a rifled barrel and it will shoot faster and more accurate.Well done guys! :)

Loved it! And yes, please give us more geekery and applied science. And Fun!

Somebody I know built a T-shirt cannon exactly like this for a science club project. He had big problems with the tank and the valve leaking air. I see you've solved those problems quite nicely. This is the best one I've seen. Great job!

Great! This was fun... I have a project coming up involving an air cannon as well... :)

Soooo cool! I loved the waltz :) Good job on the product development, looks awesome!

Wow can't believe this is your first video, awesome content already.

This is so cool I love this so much keep it up can't wait for more 😉

I love the fins!

you guys are awesome and so creative

Awesome. I have a WWII helmet too. Oh, and nice catch!

Great video and channel. Grettings from Argentina!

You guys deserve way more subs

y'all are going places

love this channel

Supreme athletic abilities like real engineers.

Great job guys! keep up the good work! greetings from italy!

That was sick

That was aaaawsssoommeee!

been here since the beginning, and can't wait to see what is to come!

Gizmodo brought me here, Awesome video!

Coolio guys keep on going, Good luck.

I was here before 1 mil subs. proud to say that.

WELL DONE , THOSE MEN !

why do you guys only have 23.013 subs??? you deserve at least a mil

well now I know I can launch my gopro hero4 session from a cannon and it wont break haha

these people are amazing

ooooooor you can put a gopro on a quadopter drone ! hahaha that was fun to see the world moving this way

Nicely done! And thanks for the MM love! ;)

cool stuff

que buen video chicos buen trabajo

Great videos so far guys. Looking forward to more. My only suggestion is to normalize your sound volume. At times your dialog got quiet.

AWESOME

this is cool

now that was cool. Can't wait till you guy's make a stable version and try to launch higher. :D

Wow..that was cool!! :)

i think this has potential

Super legal e divertido, parabéns!

Nice cannon. You could use it for baseball practicing catching pop flies.

when I saw the headline my first thought was more money than brains. clearly it's a toss up. well done gentlemen!

holy hell, if only there was raw footage without the music, that whirring sound is amazing.

you 2 deserve more subs!

thrilling shots :)

Does one of you play paintball? A set of Flex's is a pretty nice mask to just have kicking around haha

yalls is crazy smart

Maths are different with air and that projectile shape Also nice litter

What voltage do you apply to the valve? Can it work on 12Vdc, or is it 24vdc ?

Great!! Very fun... ;)

Protip: If you don't have access to a 3D printer to create the projectile, tennis ball canisters will fit perfectly inside the PVC barrel.

nice video

nice!

did you factor the speed of wind into the projectile motion equation

They should strap a Superman action figure on it and have a GoPro that would be really cool too! It also would be cool if they have his arms move when the thing would spiral

I'd be interested to see that footage with some heavy image stabilization

nice canon bro #gopro

U guys live in Oakland ?

Good job guys! (don't quit your day jobs just yet though)

Now attach a parachute that opens when its falling so the camera films the ground (cheap drone?)

nice

NEEEEEERDS! (I mean that in a good way)

Pls make a video of How you Guys made that canon

I know the song in this video might be available under who-knows-what kind of dubious license agreement, but all I can think of is DigitalRevTV now since I heard that background song first over that channel.

3:26 omg, he almost destroys his race laws

Why did the camera spin?

To reduce the spinning, would adding some weight in the bottom side of the camera housing help? Maybe then if shot from a 45 degree angle the spinning in the flght path could be minimized. Naaahh nevermind bad idea. It will still spin around...

How did the fins deploy? Spring loaded it aerodynamic effects?

Hi David and Ryan! Here's an idea: 3D print the projectile with glow in the dark filament and instead of a GoPro you could fill the space with a 0 G trigger mechanism that shoots several flashes embedded around the projectile. If you film it at night with long exposure camera setting, it would be an awesome way to actually see how different shooting angles change the trajectory of the projectiles as well as its maximum height. :D

With a few modifications, you can make a potato gun. Instead of air, you can use hair spray (the chamber would probably have to be a lot smaller) and add a piezo-electric trigger.

Very Neat - Wish You could Tweak the Fins , so it wouldn't Spin or Spin very slowly .. Still 2 Thumbs Up ! Especially the Catch & Musical Timing . . . Ha Haa Nice . .

Haha fun!!

they should create this helicopter projectile thing they can shot out the cannon to reduce the impact to the ground and also make a nice Birdseye view

can you do a vid on your cannon

A flamethrower that actually shoots out air and the air can even blow a person off his/her feet

Is the sound while the GoPro is going though the air real or fx?

Surely the equations ignored air resistance?

Can you provide the 3d printer files?

Nice. Should have gone with 60fps though.

Fucking Amazing

Can you guys go more into depth on the mathematics at 1:21?

the air cannon is easy... I want to your print data for the camera shell..

very cool the camera needs a para shoot lol

I only kinda miss the whole movie from the caught attempt, feels like you cut the most important part!

Such important work for mankind. Your ability to use the bicycle pump and shoot that into the air is almost at genius level. Most parents brag their children became doctors, lawyers, surgeons or ceo's of great companies. Your parents can brag that you've discoved a way to shoot something in the air and then catch it. Sort of like your grandparents did with small plastic army men and parachutes when they were kids. Your success rates you right up there with: elected officials, telemarketing, use car salesmen or even becoming youtube aficionados with a cult following over 500 likes! Please Please tell me your parents personally funded your education and no tax dollars were used.

Hola

parachute in tge projectile would have been more cool

3:47, play at 0:25x

all those complex calculations and you kept missing the spot where it landed exactly?

This is your 160th comment on this video

flux off haha

That made me feel dizzy

rc canonn

Now fire a metal shell from a military cannon...

First video

It's a mortar. Stop that spin, or post-process to cancel it out.

the goal of the attempts wasn’t clear and the whythis is awesome at the start of the video is non existent

Intro

Fix your bottom left text, it says "eclectical" engineering. It should say, "Electrical", other than that great video!

eCLECtical Engineering, not eLECtical Engineering. Mark rober sent me
