In this episode I made a torpedo! Initially I had planned to make a rubber band powered one but it seems that I miss-calculated the power requirements and finally ended up doing a brushless motor powered one. If you think I should do another iteration of this one please leave your thoughts in the comments below.

My Grandad worked on torpedoes for the Royal Navy in World War 2 - they had a nasty habit of coming back too! 💥😬
Yes! And they weren't that effective either. Thanks!
@@ivanmirandawastaken That was mainly the US torpedoes. They had some serious fuse issues.
@@martindinner3621 I would have gone with a basic contact fuse as a backup.....or at least a long spike going in from the nose to a firing pin lol....took the navy years to figure out how to get them to work.
@@nzkshatriya6298 The US submariners would have loved to have that option! The torps they were issued were designed to detonate as they passed under the keel of the target vessel. Very effective...when it works!
@@martindinner3621 There was an impact fuse - which had problems as well.
Right when he said it is rubber band powered, I heard Joerg Sprave's laugh
Let me show you its features!
Rubberband-powered torpedo:
JoergSprave: Let me show it's features, hahahahah!
Vedrit Mathias
Dudeeeeee Joerg is a legend
Beat me to it.
Ok if Joerg made a rubber band powered torpedo we should all be scared.
Vedrit Mathias they should do colab
Hahaha, of jeorg had a rubber band powered torpedo, I wouldn't recommend standing Infront of it....
Undercover footage of the Spanish navies new torpedo test!
Nice work
😂 thanks!
A for effort, F for result. XD
An r/c 'torpedo' that is actually controllable with a camera in the nose would be a great project though...
Submarine?
@@ivanmirandawastaken yes please! I would love to see you're design of a 3D printed rc sub. I've been doing just static printed subs for pool use with my nephew and i'm quite impressed with how well it floats and handles the water
@@ivanmirandawastaken Yeah an Rc Sub would be amazing, with depth control and everything "Saludos desde Canarias por cierto"
@@UndercastEsmeganitrospeed best bet for buoyancy control is probably variable displacement. Think giant syringe, actuated by a beefy linear actuator.
A for effort F for result is basically his whole channel in a nutshell. Amazing projects, many many hours spent on them but maybe with a couple of hours of research before starting would save him days of work and maybe increase the success rate :)
How we should have fought the war with kayaks and torpedoes
Oh Ivan, you and your enthusiastic positivity are just too adorable! 😍
It's multi purpose. By removing the cap, it can also be used as a depth charge.

Thanks for all the likes!
Lol

if the torpedo is anything to go by,
i dont think the us needs to worry :-)
Build an atomic bomb out of 3D-printed atoms.
Johannes C o’oh thanks for all the likes’
Just over 400, yep, that’s a lot. So many. I’m amazed. I am NOT being sarcastic
You need a contra-rotating screw to balance the torque. :)
I felt like 'this guy's English sound very Spanish', and then: "damn! that's my city! San Sebastián!" lol haha! awesome!
I've been having Ivan withdrawals. I clicked like before even watching the video.
So much this!!!! 🤣
@@welbot You can't not like an Ivan Miranda video. 😉
@@BV3D haha indeed! Especially ones where he loses his glasses in the ocean 🤣
Hilarious! I was cracking up when the first test sank as soon as it came out the launching tube 😂
Thanks for sharing your mistakes as well as your successes!
It was hilarious, in the footage you can almost hear my friend laughing underwater
@@ivanmirandawastaken laughs in underwater
This can be greatly improved by changing to a lower "kv" (lower rpm) motor.
Decide how fast you want it to go and then match the "pitch speed" of the screw to be a bit above the desired speed.
Pitch speed is rpm times the distance the prop moved forwards during one revolution.
What you have now is a prop that tries to create a vacuum around its blades (cavitating) and that makes it very inefficient.
Bigger diameter will also help since you want pushing power not high speed (water resistance will quickly overcome the force of the motor so going fast will take a lot of power)
What I have is a prop eating air like crazy not cavitating. I wish the prop was spinning at cavitating speeds, that'd mean serious speeds but with this huge prop and that tiny motor that ain't gonna happen.
@@ivanmirandawastaken Can you calculate the displaced volume from your cad design?
Then if you can match the total weight to the weight of the displaced water (or slightly less) you end up with a fully submerged torpedo.
Or you can cheat and add waterproof servo's with fins to create a dynamically dicing submarine in torpedo shape.
I'm convinced Ivan has just about as much prototyping experience as anybody else on earth.
The enemies of Ivan have nothing to be worried about, except for being tickled by soda bubbles.
Ivan, the best thing about your videos is how you laugh off any lack of success (I won’t call them failures) and jump right back in and try again. You are truly an inspiration.
Gotta feeling that the FBI is closing in on your coordinates.
Ups
Next project , sponsor by FBI
I don't think the FBI operates internationally
Yezh, that would be CIA.
@@tomf3150 Central Intelligence Agency of america (CIA is america only mate)
every time I hear someone say "spacer" I end up hearing Ivan saying "spacer!".
My kids totally fell in love with that exact beach/bay. We will have to return. Your friends are amazing! Love the looks of the torpedo ... and it seems quite peaceful, too! ;) Cheers and thanks as always! JM
That was harder than expected. It took a couple of generations to get the torpedo to work.
Oh Ivan you are such good value - I haven't laughed as much for some time!
Do you plan to take this around and show it off? A torpedo tour... a "tourpedo" if you will. 😏
You never disappoint
@@ivanmirandawastaken Thanks! I've been missing you and JAYTEE, you know.... Will JATOG be starting up again soon?
This dude's skills are just astounding. Great Work!
I've always found it really enjoyable how half the time the entire build process is more exciting than the field test.
All this planning and work. Doesn't work. Then you Iterate and try again. Creating is fun. Definitely more fun when it works but still :D
So much of effort man, I have been following you from past 2 years
That was brilliant I kept laughing out loud. Ivan can do no wrong!
Thank you Ivan, you make me smile and laugh a lot. All the parts you print, come out looking so good.
Where did you get the files please? could you send it to me?
Eres un máquina macho, llevo unos meses iniciado en la impresión 3d y trabajo en una oficina técnica haciendo planos y tu imaginación y sabiduría marcan mi camino !
Gracias !
Thank you for impaling our creativity 💟💟💟
That excitement of his makes me happy
What is going on with the video at 5:17? Some weird artifacting.
So Ivan has now officially graduated into the evil mad scientist category since he's now developing weapons!
Pirates will love this design. Sink the ship and plunder!
This video has inspired me to make a mini torpedo that I can drop from my rc airplane. Quick suggestion though, I think torpedo would work better if it had completely neutral buoyancy so it doesn't sink or float, also if it launches from the underside of the kayak so it has water to use to push it out behind it. Also I might have sanded it down using something like 180 grit since 3D prints tend to be not very hydrodynamic so that 180 grit would give it a nice smooth finish. Awesome video though keep it up.
When a war breaks out, I hope you'll be on our side.
“Look who has a torpedo on his table!” 😂
While this is a great project, I think this would get Kayaking banned in California.... :(
You mean it isn't yet?
Nobody:
The guy's enthusiasm: ^^^^^
It is my life goal to launch an explosive torpedo with guidance from an RC ship... mind you I'm talking VERY small "explosive" but yeah hideously dangerous. Hence why it isn't done yet... :P this is nearly as rad.
Burst disk FTW.
Just be careful
...well now you know your next project: an rc submarine with go pro, to search the glasses....
No joke, you are bonkers and my kids love you as do I. Keep it up.
Yay! Thanks!!
The large lateral holes cut in its sides are allowing a great deal of water into the body of your design and creating drag..... If the holes must remain for legal purposes, I suggest covering with transparent tape. ... Or make the whole thing from a translated plastic and the holes will be unnecessary.... Great video altogether. Amazing ingenuity.. Love the comedic commentary...
It needs to be a high pressure gas such as hydrogen
10:25 At that rate an aircraft carrier can dodge that torpedo 😂
I think an aircraft carrier could avoid it even by letting itself drift away on the current.
2nd iteration would be to make the torp heavier to counter the buoyancy of the plastic shell to a certain depth. This ensure the propeller is fully submerged. Add fins to stabilise(have a look at japanese torps from WWII). Use compressed air to drive the propeller.
Great idea.. thanks for giving me a great idea for a project... 🤘🌞😁
Me mola tu torpedo!!! Enhorabuena por el artículo en El Mundo!!!
Gracias!
I like the enthusiasm! Good luck!
Damn i like this dudes energy 👌
Laughed a ton. Good job!
Hay que risa con el torpedo. Gracias por hacérmelo pasar tan bien viendo el vídeo.
Kaboom! Great video. Nice build. Mahalo for sharing. : )
A very fun video! Thanks for the view! This idea could be tweaked to perfection with just a little more engineering. Gear boxed low speed high angle prop, and some buoyancy trim. Torpedo needs to run completely submerged all the time. Prop housing needs to be eliminated and add free water larger diameter trolling motor prop. All in all this was a very interesting video! Excellent build as a proof of concept DIY torpedo project!!!! Well done! I hope you tweek itto perfection!!!!
Can I just get a clip of 11:32 playing on repeat forever 😂
5:25 i can’t be the only one seeing his face glitch wtf
Ivan, how can you find your glasses without glasses?
Hopefully you have glasses back! As always nice video!
Lost them forever😂😂
You should post how long all the stuff took to 3D print.
Years per project... his wife Still looking for him....
A lot! The front big piece around 12 hours with a .8 nozzle
@@ivanmirandawastaken Dang! Larger nozzle makes sense.
@@DanSteigerwald He also need time to design this , video editing etc .... a lot of work for every video.... Ivan you are a Hero.... a lot of creativity
My favorite part is everytime the end haha im done xDDD
Awesome! Though It’s probably a good thing you don’t have easy access to explosives 🧨:D
*Rubber powered torpedo* JoergeSprave would approve.
Great job! Looks like It will probably work better when completely submerged a few inches under the waterline. I'd try to add even more ballast. Could also help if the launch tube would be completely submerged when launching.
At the beginning I thought: rubberband? You are a powermotorguy. Thanks god you realized that. You're a powerful man so you need powerful motors. Motors and screwdriverhammers for Ivan.
Really fantastic videos, as always!!!
You always make the most interesting things Ivan.😁

I love his name Ivan and the insane laughing.
I missed you!
I missed ya'll too!
@@ivanmirandawastaken Be glad it wasn't a real torpedo - my Grandad told me the ones he worked on during the war sometimes came back! 😱
Love this build
Thanks!
Ahah there is very nice friends u have if you were one of my friend i think this type of situation could be reciprocal xDD i remember have tested my handmade e-bicycle at these hours lol
Morning people ftw!!
Great work!!! Do you have any tips for a student that wants to learn how to design and make stuff like you? I really want to, and would love if you could tell me the best ways to train or practice. Thanks
I'd start by making, try and fail. The internet can show you the rest.
You made me laugh again like never !! Thank you for your madness you are so inspiring :)
Ps: did you find you glasses finally ?
Nope. In the sea forever
Great video again
Real torpedos have two counter rotating propellors to avoid the torpedo counter spinning.
That was bonkers, I liked it.
As always... I LOVE IT!!!!
Using a chemical reaction like sour salt and baking soda because when water is added it fizzes up
The torpedo wouldnt sink
The dual powder method would fix that but
If that wasn't what you were "shooting for" then it was awesome
That was hilarious!
Ivan Miranda: the one man navy (with help from his friend). I hope you found your glasses
Nope. There's now a smart looking cod somewhere in the ocean.
@@ivanmirandawastaken oh, hope you can get a new pair soon in that case
Should have used the giant rubber band as a resistance launcher to get the torpedo moving then let the motor maintain speed
Ok for launching out of the tube a plate with a heavy spring, with the tube out of the water or fully submerged. To get your torpedo to move quicker ou need it to have neutral bouyancie, so it runs about a foot or Two below the surface. I hope you revisit this project one da would enjoy seeing the Mark II.
After 100 years, u will be a legend...😁
Add Mentos candy to Coke & it explodes very much. if you have have the coke with the hole in the cap with foil & a second chamber with 2 or 3 Mentos candy's & another hole with foil when the Coke chamber has a minor explosion into the Mentos chamber the explosion will be increased greatly as it fly's out the front of the Mentos chamber.
Torpedoes normally are launched by compressed air so you could put a rubber skirt in the launcher that goes around the torpedo & for a huge amount of air into the back section which would blow the torpedo out & it really needs a bigger propeller to go faster. But anyways well done for a first try.
Common Ivan, even the Russians have figured it out. How hard can be 😅
You need ballast under the torpedo. And you need a efficient propeller with rudder control.
Efficient propeller like your jet boat system.
3:18 Was hoping he was going to say RDX.
I know this is an old video, but the reason it is turning is because of the torque of the motor. You can counteract this by a second motor going the other way, or an easier way to do it is just have fins on the output of the propeller in the opposite direction. When tom Stanton made his hovercraft he had a similar problem
You sound like my Italian cooking instructor
.. good job I like the the quick release hit with the paddle then it sank .. in stiches .must say you gave me a great thought in building an I.O.M rc sailing hull..also a torpedo with sails now theres a thought cheers
You invented a "Turn-pedo". Sorry you lost your glasses, I bought spares the other day. Great effort mate. Cheers, JAYTEE
The enemy is quaking in their boots, they have refused to launch their battleships in fear of Ivan sinking them.
your child-esque glee pleases me. Now let's talk chemistry to make this torpedo more awesome 😉
Nice work and back to the drawing board... good luck
For me "Torpedo Launcher - Mark 1" would be a good name; but, for you it should be "Torpedo Launcher - Ivan 1"
Funny
2:16 five yr old me trying to put the block in the circle
Thanks for showing all the obstacles!
What's that red handled tool you use to clean out the holes before inserting fitted parts?
Nice job! You crack me up, funny!!!
Como se nota que eres de España😁👍 saludos desde Cataluña! Soy nuevo sub.
