Building a DIY submarine 

We need a submarine re-visit please, Matt. I was grinning like a school kid the entire video. It's just too awesome.

I'm enormously impressed with your ability to find parts that fit together with minimal modification.

I think the CEO of OceanGate believed in the DIY submarine a bit too heavily.

Those ocean gate engineers should pay close attention

Has a more complicated controller for a homemade toy than ocean gate had for a craft holding 5 people

Had so much fun working on this challenge! Can’t wait for our next collab and to release my video showing my ROV finally working perfectly! 😃

Matt in 2047: "DIY moonbase with life support"

I bet this is way more resistant that Ocean Gate sub

This aged well

So many youtubers underestimate the power of them explaining what they are doing as they do it. I made it 15mins in without thinking about it and rewinded multiple times to really comprehend what you were saying before being pleasantly surprised this was a 30min video. Big fan of everything you do and especially a fan of your knowledge and ability to explain and articulate. Definitely smashed that sub button.

It's hilarious how this is being recommended to me now

DIY Perks will soon show us how to create a spaceship, DIY STYLE!

Algorithm got that dark sense of humour with the recommendations.

I think a guy watched this video and is now trapped down with the titanic

Stuck in bed rest, fighting a fever but after watching this, I just wanna get up and build something. People like you make life worth living.

I remember thinking "I could make this if I had a soldering iron." Now he's making a submarine.

OceanGate Inc furiously taking notes as we speak.

Hey you. Yes you. I know you're looking for THOSE comments.

Can't wait till 2031 when you start making guides on how to build DIY Nuclear Reactors.

Between yours, James and Peter's recent subs I think I need to finally get off my ass and make one to take off the coast. They look like such a challenging and rewarding project.

Now you're ready to go visit the Titanic.

Yt algorithm knows what it’s doing 💀

Those billionaires should have watched your video before launching for the titanic

The plunger solution is brilliant but the whole project is outstanding

Okay you can't convince me he isn't speedrunning his way to evil genius

RU-vid is shady man... recommending this now😂

having this recommended to watch just when the Titan submarine has gone missing, i wonder if they watched this when building theirs

ngl, DIY Perks are one of those few youtubers who actually do what they put on their thumbnail and makes that so perfect that i could actually be sold to costumers.

"I was a bit worried that it looked too much like a bomb..." "Next up, I will be filling up the clear plastic casing with four kilos of sharp metal pellets!" :D

Some billionaires should have watched this

Hits different June 2023 💀

This looks like a spaceship. The part with the linear resistor is brilliant, an absolute 200 IQ move!

The yellow submarine was more of like the "exploring" type of submarine used by researcher vessels. Whilst the one you made is a full fledge nuclear attack submarine haha

RU-vid really recommends me this the day after the Titan imploded?😅😅

RU-vid real funny recommending this now 💀💀💀

Is there some submarine build fad going on that I don't know about? Always love the clever engineering of this channel.

DIY perks: "I think it migth be too buoyant" England: "Oh dear!" 19:51

The timing of this video being recommended is impeccable

Why is this suddenly showing up on my RU-vid feed?? 😳

This is a long way since reusing laptop parts for other applications, the creativity in this channel is just absolutely awesome

Refined Design: I would say remove the steal pellets, and replace them with more batteries and for sure more powerful thruster engines :)

RU-vid algorhythm playing a sick joke right now

Honestly shocked we didn’t hear something like: “Now this first section here is for the ℙ𝕆𝕎𝔼ℝ ℂ𝕆ℝ𝔼. I’ll be using a small molten salt nuclear reactor that I’ve cobbled together from some leftover bits lying around the garage, but you could also get away with lithium batteries if you don’t have the supplies available.”

I know what comments you’re looking for. Admit it.

Next video: "ICBM are Intercontinental Ballistic Missiles. They are basically very big missiles that can travel across continents to hit distant targets, usually with Nukes. Normally, they are viewed more as deterrents than actual weapons, because as soon as one of those is launched, all Nations that are also Nuclear Potencies will also launch theirs in what is called a MAD(mutually assured destruction) protocol. This would most likelly destroy all major cities in the world, cause a nuclear winter, and possibly end 80% of complex lifeforms in the planet." Today I will show you how to trigger a nuclear apocalypse with this DIY build!"

Love the project. Can't wait for version two! Three suggestions: 1.) Use a sensor to determine if the sub is level and then you can automatically adjust the two boyancy motors. There is a good chance going faster or going against currents will alter your level. This can easily be done with a cheap rc flight controller. It's overkill, but cheap and easy. Someone know of a dedicated sensor? 2.) Instead of having separate sets of thrusters to rotate and also "slide" left/right, just use one set of four. Engage 2 on one side to "slide" and engage one on each side (front/back) to rotate. 3.) I love Mr. Gadget's idea of a periscope. However, a traditional one would be very complicated. You already have a floating periscope platform where your receiver is located. Mount a second camera/video-tx with the ability to rotate and you can really take advantage of the long range that your rc set-up allows. Plus you can look around without having to surface. Disguise the whole floating part as a lilly pad and you have a true watery spy craft!

When you build your submarine by watching youtube videos. IYKYK #titan

Brilliant! What a marvelous first attempt! Would more batteries and larger thrusters be better as ballast? Let the additional mass work for its passage instead of 'deadheading.' :)

Imagine replacing the steel pellets with extra batteries. That would be a lot of power!

This picked the absolute perfect time to pop up in my recommended lmao

RU-vid is FOUL for recommending me this lmao 💀

Matt, don't forget about safety! If the sub goes too deep, it can pull its antenna under the water and you lose control. It is necessary to add an emergency system that will force the boat to surface if the signal is lost. For example, dump the ballast.

So many clever design choices, lovely build.

RU-vid Algorithm doing God’s work recommending this June 2023 🤣

This guy's creativity, problem-solving ability, knowledge and enthusiasm are outstanding. I enormously appreciate the effort he must put into making these videos and the sacrifice it implies in comparison to other youtubers who spit out new videos at least once a week. Thank you so much!

Please bring this back, I'd love to see an even more improved version of this, it's already so awesome. Hopefully a lake trip too, goddamn i didn't know i loved submarines until today!

OK this is such a cool project!

This submarine has more safety features than titan

Huh lots of submarine videos getting recommended to me for some reason.

I like the fact that the most convenient thing he had on hand to demonstrate something sinking was a small motor

An older AM transmitter and receiver has a better submerged range, or even a 36MH FM set, also the analogue servos are a great idea as they require less power the closer they get to their commanded position. Digital servos are always using power to 'hold' in commanded position - slightly different system. Great project, loved it

Sigh **clicks on newest comments**

This is what my middle school stem class submarine project wanted to be but never ended being

Next episode: DIY Yamato class battleship using only soldering and brass!

11:00 you don't need separate thrusters for rotation and translation, this can easily be achieved through channel mixing in your radio.

oh boy... this video about to get a surprising new wave

ocean gate should have hired you

When you replaced the variable resistors in the servos with sliding variable resistors, mind = blown. Greatest plot twist in non-fictional tv

Damn man, am an engineer and i rarely get impressed by RU-vid's DIY projects, but almost all your projects impresses me, like in this the way you modified the servo is simply genius!

Too soon, RU-vid algorithm

I love the fact that every project he starts and puts it to work he has so much joy that it works Pure joy Very rare these days

let me guess, your next projects is DIY GUIDED MISSILES with sugar rocket engine!!!! 😎👍

THIS WAS SO MUCH FUN. I didn't expect to enjoy a submarine build that much, but I did. Keep surprising us Matt.

Ocean Gates should hire this guy.

I'd love to see what I imagine to be hours and hours of planning, design, testing, and repeat to get to the designs that you've made videos on. This skill in itself is invaluable to aspiring creators/makers and all your videos completely skip over this step.

Anyone else notice a lot of engineering creators making submarines? They must know something we don't

I really like "unrollling" the servos into the syringe position control. That's great work, every part presented was more clever than the last. You can economize on your thrusters though! You currently have 4 translational and 4 rotation pumps. You should be able to use the transmitter's mixing control so that (for example) the left-right of the throttle stick runs opposite ends in opposing directions and the left-right of the right stick runs them together for translation. That will free up 4 pumps and 2 channels.

bruh!!!!!! WHY recommended now 💀💀💀💀💀💀

It is hilarious that this is being shown to me on the homepage 😂

The U.S. Navy has a project called SeaPerch that is a STEM outreach program for high schools. I suggest looking into it for some ideas. I remember reading the documentation, which was designed to help student overcome various obstacles using very cheap solutions. One thing I noticed that you may want to look into is the tethering cord. ROV tethers are neutrally buoyant. If I remember correctly, the solution they came up to that issue was to attach pieces of foam pipe insulation every foot or so to counter the weight of the line.

The hard part is to explain to other people that you're not building a nuclear reactor

WHY IS RU-vid RECOMMENDING THIS AFTER OCEANGATE 💀

People coming here in 2023🌚

this man went from literally designing a silent pc cooling system, to making submarines. hats off to you man.

Words can't explain how cool the creations he does are, honestly it's really opened my eyes to science and other stuff that at first didn't really appeal to me.

Of course I’m just now getting recommended this

im just here for oceangate comments.

The problem with your "competitors" sub may not just be the weight of the tether, also the fact that that he used water to achieve neutral bouancy. He will naturally have slack tanks / free surface effect, causing the weights to shift with every movement. Best option to achieve neutral buoancy is permanent (ie fixed) ballast that does not have room to move. It is possible to achieve this with water, though you need to reverse engineer the weight needed. Your idea to work from the center, with the battery pack probably being the heaviest, made it probably have naturally more of a neutral trim, though it seems that after adding the weights you have small trim issue, probably meaning you are just a few grams off in one end as it is floating quite well from the looks of it. Would love to see how it behaved in a bit deeper water though, it seems to be quite decent, though maybe a bit underpowered.

He’s right on his way towards “DIY Nuke- the Biggest Blast!”

I have been watching and even playing with simple submarine toys geared towards kids for much of my life but the first minute of your video did an amazing job helping me understand a basic law of submarine "how they work", before I knew enough to know i was missing something and NOW i know enough that what i was missing was what you explained in the intro of your video.... thank you so much!

Who’s here after the ocean gate titan incident-

You very clearly explain your every action and what you do in general. I've gotten a little smarter in the last 27 minutes!

Very cool build~ If you want to try a design without a tether you could use a radio operating at a much lower frequency that'll stand more of a chance piercing the water. As you pointed out 2.4GHz just gets absorbed too quickly for any useful depth. As a precaution you could have it surface on loss of contact by binding one of the channels to always transmit. When the receiver loses that signal have it surface so you don't lose it ;)

I would honestly love a full video of just feed from the submarine. This was so fun!

Stockton Rush behind the camera saying "Make sure you say Carbon fiber is good!" "Say it!!! say it!"

“I’m feeling neutral.” What a Matt thing to say.

I love how he explains the reasons behind selecting a particular component.

2023 has the plans for the sub been revised 😅 love your channel

This was epic! One of my dreams was to join the design school while I was in the US Navy. It was amazing to see you make an almost perfect first attempt at a real sub.

Your videos have a certain quality about them: they are pleasant to watch, relaxing and calming even, due to fluently but surely moving the viewer into a creative and positive mindset. They also emanate a contagious enthusiasm. Keep this on. :) This is your trade mark, your own creation you can be proud of and feel fulfillment about, Matt. :) Cheers!
