  • 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! 😃

    • A realistic 3d printed submarine body would be cool for this

    • #thank you so much #srsachinsr

    • @Iron Clay Ummm, I don't think that's really on our agenda, but thanks for your faith in us ;-)

    • Loved your design, but I really think power needs to be local, rather than tethered.

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

    • @Nathanael Malm Russians when they see the video:COPY THAT BLYAT!

    • @Dito Alfrido I can see an application for that to fishing, like under an icy lake

    • Don't show that video to Russia

    • @LFM so a torpedo XD

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

    • @Nisco Racing He should develope nuclear power too in case to intercept enemy invasion from intercontinental.

    • @Jane Doe Now we need missiles too.

    • If he is going for faster propellers, he needs to minimize cavitation noise. You know, in case of enemy submarines in the area.

    • @Ramdom player201 the buoyancy balance can be adjusted using the syringes on each end.

    • I think the steel pellets are used to make it easier to adjust the weight distribution to keep the submarine level etc

  • You should make an emergency surface system, where if the Internal pressure reaches X, the syringes start to quickly empty.

    • @TAPS147 iirc a barometer measures air pressure

    • or measure water pressure

    • @Rey Arias I belive a barometer? Perhaps and electric one

    • How would you measure pressure? Unless there’s a circuit board for it?

    • wow.. good idea man.

  • "Without calculation"? That was hilarious. This project required an amazing level of deep insight as well as an enormous breadth of comprehension of physics, electronics, and mechanics. I learned a lot from this great video. Thank you for your insane curiosity and passion for experimentation. :D

    • @Anonymous user anyone? Nahh.

    • Nah dude, it's not an amazing level, anyone can reach this level in a few youtube tutorials. If you aren't just trying to cleverly flatter him, give it a try. Find some cool idea that you'd like to make real and slowly learn what you need. It will be a lot of fun

    • Haha yea I had a good laugh at that as well. I don't know how accurately he calculated it in the end but approximating it with a simple cylinder should really give close enough results to achieve that neutral buoyancy roughly :)

    • agree

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

    • Walmart?

    • 3d print

    • Yea, he had done the job well👍

    • lol. you're here. now you better compete with them, wanted to see your invention too.

    • bro its magick he use magick

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

  • this man is like: "if you want something done right, do it yourself" and I took that personally

  • This guy is a genius. Absolutely impressive and stunning work.

  • Could you make a diy Sivetz fluid bed coffee roaster? They are simple in theory, but crazy expensive.

  • Matt in 2047: "DIY moonbase with life support"

    • For a moment and at quick glance i thought you typed Matthew 20: 47 😅🤣😊

    • CG5 look alike

    • Nah that comes out in 2028. I know this because I watched his diy Time Machine in 2052.

    • 2100 DIY planet😂

    • DIY GUN

  • OK this is such a cool project!

  • One thing you will have to contend with is, that once you begin to descend the water pressure will compress the shell causing the internal pressure to increase causing the buoyancy to over react. The sub will descend faster as the water pressure continues to increase. As you showed in the first part of this video, increased internal pressure causes decent.This causes a runaway feed back. Using dive planes will lesson this effect but still you will have to continually correct your neutral buoyancy. You could use an ARDUINO to sense internal pressure and automatically compensate.

    • That is true, but the effect is much less than pronounced than with a human diver, as the shell is on this sub relatively hard and and will not compress much over the working range of this sub. Human divers have lungs and (usually) BCDs which both have a "soft" shell and so are easily compressible and provide much more positive feedback when you dive.

    • @Terry Pold Good point and he already said he will do improvements so I hope he will add some sort of Arduino solution like you're mentioning. I don't think it would be overly-complicated and especially not for DIY perks, he can probably figure that out easily.

    • @Teh Blacksmith that's assuming the sub is close enough to reach the float without swimming out to retrieve it. And, of course, the float is not a tether it is just a fine wire used as an antenna. It might not pull the sub up. Then again it might. Who knows. I was saying this because I noticed when it did submerge it seemed to start slowly and then went down quickly. I'm looking forward further attempts. I expect he will be encountering the same requirement as real sub designs. I'm sure he can solve them one at a time.

    • It's pretty much accounted for considering that it has a float, if the sub does become uncontrollable for whatever reason he could just pull it up himself

    • Maybe add a leveling system with that Arduino that can run the plungers for level ascent/descent. 1 knob for that, the other for selectable front/rear tilt.

  • Very cool project there! I have two suggestions for future model(s): 1. Instead of adding steel pellets to add weight, would it not be awesome to add more batteries? 2. Also, it would be a next level submarine if you could change to a frequency that can propagate under water so you can eliminate the floater and make the submarine 100% self-contained.

  • I genuinely might try and build this, I've *always* wanted an RC submarine with live cameras! And if you swapped ballast for batteries it could have INSANE endurance!

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

    • @motorbiker46 know this is an old post but just wanted to tell you to keep at it. I hated soldering when I first started because it was difficult to do cleanly and get good connections. But only through trial and error you learn what works for you and what doesn’t, now I love to solder and I even started doing work for a local jewelry store repairing different things. Not a career by any means but pays $20 a job and some take me only a few minutes.

    • @Reclaimer Leviathan True, that is something I keep running into. And it will be even worse once I finally get a welder and start learning with it. From what I've learned so far, old rusted metal that is easier to find just laying around is a major pain to work with.

    • @motorbiker46 Yeah, but how much of the lack of skill is due to inexperience thanks to a lack of materials? If you had the materials/space to work/time, you'd eventually build the skill. You can't build the skill with theory alone, and if you're learning, learning by doing is the fastest way to do it.

    • #thank you so much #srsachinsr

  • I love this! I saw a few suggestions about adding pressure sensors to monitor internal and external water pressure. That would be pretty cool, but I expect that you are not going to exceed the length of your tether, so maybe a submersion sensor on the tether float to activate the "emergency surface". Of course, that tether won't do you much good if the float can't hold up the sub... I would also suggest a compass that you can see on your heads-up-display. That way you can keep track of your boat's direction of travel and know where your torpedoes went after you shoot your buddy's little ROV. Really nice job (from a former US Navy Submariner - RM2/SS).

  • Having worked with UUVs and making creative upgrades to them, I'm glad that ours was a commercial one because buoyancy was a pain to figure out... We just had to slide weights fore and aft based on temps. This is amazing to see though and now I want to make my own to get back into that life

  • I think I had fun just watching this video as it's full of informational content. The next upgrade in my opinion should be more thought. maybe the sub will have powerful thruster engines and a long arial antenna like the one we see on old cars so that even if the sub goes down you could still have a signal. Anyway with your ideas and execution this project is a win

  • This an amazing design and super neat modifications to servo motors, you make it sound so easy!

  • So many clever design choices, lovely build.

    • @asdf I mean the last sentence is pretty damn sharp. Except that you could have said i saw something similar/a similar model was made before

    • @Alka Upadhyay Sure ilaward.info/long/VWgzB82P4xCq95byMwky-w.html btw i never said that DIY perks are bad. OFC they need to get their ideas from somewhere - and they did a great building!

    • Well there is a similar project on ILaward from few years ago.. Nearly the same design. So thus one here is simply stolen to make money through ads ^^

  • I love how you were like a kid in a candy store trying out your final design. :D

  • Love this mans videos. Has a real knack for this. He’s well spoken, clear and concise, straight to the point, well knowledged. You can tell he really enjoys what he does. And the best part? He does sponsorships with company’s that provide fun and exciting educational experiences for our future generations

  • What an amazing project, to go from a concept to a near spot on build first time round is pretty incredible, then to iron out so that a 2nd test is near perfect. But I totally agree with one comment about using more batteries to give you the 4Kg of ballast needed to give neutral buoyancy would be a good mod. I nearly purchased a flying drone but I can now see an underwater drone is by far as interesting as any flying model and I cannot think of any regulations to break with one of these. Star rating it has to be tops 5 stars!!

  • This is so cool, I think I might try to build it myself, as I lost one of my RC warships in a pond as it tragically sank in 2019, and it is an enclosed pond meaning the wreck will still be there, and it could be really fun to go on a sort of rescuescavenging operation to check out the wreck and other stuff that could be there

    • @Cameron Evans thank you!!! I’ll try my best to build it and will keep you updated on the progress!! :)

    • You should build it! Definitely keep me updated on here and lettme know if you find your long lost ship!

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

    • #thank you so much #srsachinsr

    • And other people are watching island boyz trying to rap

    • Wait I was halfway through, and I didn't even realize that it's 27 minutes, wow!

    • so true...

  • this man never seizes to amaze me. Your work has given me inspiration to try stuff like this on my own and see what I can create.

  • Just another idea when you go to revisit this project, there are 2 axis camera gimbal mounts for RC. You can also get a clear acrylic or poly dome for the front of the sub if you go with a different propulsion method giving you a camera that can change frontal viewing angle. I love that you built the power into the sub and didn't decide to feed power externally, this cuts down on cable gage outside the submarine since its not transmitting power reducing drag. I don't know if it would work, but if you wanted a cheap cable cluster between the submarine and Bouey, maybe strip an ethernet cable on both sides? If you try it and it works, you can theoretically buy a 1000 foot box of the stuff and now you got yourself a whole new class of submersible if you scale up the power some and capacity alot for ocean diving.

  • Matt in 2090: let’s build a DIY interstellar spacecraft, with ultra sonic rocket engines, and oxygenation systems.

    • @D P lol

    • Matt in 2140: DIY clones. Immortality has been achieved, Matt self replicates. 2168: The Matts have decided to become sovereign, Matt breaks away from humanity colonising the Moons of Jupiter. 2479: Earth is under threat of destruction from a rogue planet. 2480: DIY planet buster, The Matts have returned to protect Earth. The planet buster destroys the rogue planet and all humanity rejoices. The Matts return to their home world.

  • Love this content makes me want to keep building stuff out of parts

  • 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.”

    • @Seraphina I am aware of it. But I prefer the made for TV movie where the kid builds a bomb starring John Lithgow

    • @Rund ums Fliegen the next video is mini torpedos and a periscope with a small directional camera

    • @IRMacGuyver This makes me wonder if you heard the story of teenager that actually did that and literally tried to build a small reactor. If not suffice to say they succeeded in contaminating the local neighbourhood. Probably not surprising considering that forcing a nuclear reaction of some kind isn't that difficult engineering a system to isolate, shield and get power out of it is harder.

    • 🤣

    • Diy nuclear submarine. That would be a neat story at parties

  • You Sir are quite impressive! This was a beautiful and complicated project that you made look easy. I subscribed!

  • I'm so impressed with this 👏🏻 amazing work and hope to see this used again in deeper water. Great video 📹 👍🏻

  • I am just in the awe about how much engineering went into this and your dedication. Your channel is a Gem in ILaward.

  • Wow, really well thought out design ! That was so cool when your submarine started to descend in a controlled manner. Enjoyed listening to you explain your design choices.

  • 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.

  • Imagine being so good at engineering you don’t need to make calculations

  • You're always able to inspire the engineer in me! It was too exciting when it went down into the water. Thanks for the awesome content!

  • I absolutely can't wait until there's a version 2! This was awesome!

  • Cool stuff ✨ I am studying electronic control, I had never understood so clearly what a servo motor is! I realy enjoy listening to your videos. The effort on them is remarcable. greetings from Mexico

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

    • all videos are exelent.Treasure in youtube.Knolage,nice voice,systematic in all aspects...Genious!

  • The thing I particularly like about this is your thrusters. They are so minimally invasive that they don't disturb the wildlife. Meaning you actually get to see some stuff rather than it all running scared from a big choppy prop.

  • Amazing as always, though I got to ask. How many of your projects do you actually really use, on even a weekly or monthly basis?

  • You are both masters of design and implementation. True tinkers. This production was so enjoyable to watch thanks 🎅 Xmas 21

  • Wow such an amazing project. I love the details in your idea and engineering. I would suggest printing a mesh for the water inlet as stuff can go inside and clog.

  • It was so good to see how excited you are, especially from 22:50, you were excited like a little kid with it's toy, and that's why I love DIY, it is really a good hobby. And of course, this is a beautiful and complex project, congratulations for the success!

  • thoughts on adding a secondary backup system to the buoyancy control where if the primary system loses power, the secondary system kicks on to flush the onboard watertanks causing it to rise?

    • I'd suppose it isn't really necessary when it's tethered to a buoy on the surface. But it's totally a real concern if he's able to do away with the tether.

  • The submarine feels as though if it could be used from afar you could explore the ocean from your bedroom. (could you perhaps make a game station from a broken laptop by adding a GPU through the mini PCIe, and adding an external wifi card? There can also be an external USB hub, and costs could be down by fixing a faulty GPU or buying a used one. It could be a cheap way to game thanks. )

  • For real, I think I was just as excited and amazed when I saw the thing go down! As always, your videos deserve more than just a single like button. I'd literally spam that thumbs up button for all your vids if it's possible. Cheers!

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

    • DIY Guide: That everyone can do with their thing's at home

    • Actually "Building a space rocket DIY style" will be this channel's 2021 Christmas special :D

    • Can't wait 😊

    • "I had to get this video out so I didn't do the necessary calculations, let's just see how this goes!"

  • Awesome build, I love this design concept! Can't wait to see more tests and refinements on this project! Cheers and happy holidays :)

  • Is there an indoor pool that you can play around in? Warmer water and a much more controlled environment would be great for testing :)

  • This was so much fun to watch. Many, many years ago now there was a discussion amongst local Makerspaces of making a drone that could travel between all of them. It would be an interesting challenge considering the various terrain, distances, and legal considerations. Given that two of our Makerspaces are near the water, I had suggested doing a land and sea drone, so that idea has been playing around in the back of my mind to make some sort of submersible drone for quite a while now. This may become a Spring 2022 project for when the outdoors is not quite so frigid.

  • Beautiful usage of the variable linear resistor on the servo, I learned something new, hats off to you sir. I wish I could know how you wired that resistor though.

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

  • Adding extra batteries would have helped with Buoyancy, as well as increased the operation time too.

  • Dude. I am always impressed with what you make, but this is on a whole new level. And you did this without initial calculations? Jesus, Matt. You are so talented, it's unfair. 23:03 maybe one of the most satisfying things I've seen on ILaward. Brilliant.

  • My dude, I'm literally geeking out at how ridiculously awesome this is! Instant sub, I genuinely hope to see more of this (and improvements) in future! Massive kudos dude!

  • Wow, Matt, I am really impressed with this project.m I can't wait for the revised attempt. You are one intelligent guy, sir. Thanks for sharing. Felix

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

    • @Dihan tesla is working on that. 🤣🤣

    • That was episode 124

    • David Hahn already went down that road. [Edit] I didn't end well for him.

    • Matt would probably go for DIY functional Tokamaks...

  • What's important is the feeling you get after a successful completion of a project, and it works exactly as planned. Great work Love your projects

  • Amazing project! Always love your DIY projects but this one exceeded my expectations immensely! Please keep coming up with projects like this!

  • It is really inspiring watching these impressive projects being implemented by you. Looking forward to the next submarine video)

  • Looks great! Be cautions with deeper waters, the higher pressure makes it harder for the motors to expel the water in the syringes.

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

    • @Seraphina thanks, didnt know that

    • @spacegamer In case the sub hits turbulent perturbations in the water that either messes with it's roll directly or even it's pitch (Operating either of the buoyancy controls in isolation will also cause roll as it lacks the counterrotating screw to balance the roll torque it produces).

    • @Wolf why would you need roll control?

    • no roll control tho

  • at 19:08 Are those swans mocking you or are they just wondering what you're trying to look at down there?! Great project. I'm a first year robotics engineering student, so I really appreciate the way you explain the build and the concepts.

  • Amazing project! Always love your DIY projects but this one exceeded my expectations immensely! Please keep coming up with projects like this!

  • Given all the awesomeness in this video I am going to declare my favourite part to be the underwater insect inspection: "That is an interesting piece of wildlife." Very David Attenborough ;) Extraordinarily impressed by your ingenuity, such a fantastic project!! :D Thanks for sharing your awesome with us :) /Lizz

  • This is so cool. I can't wait to see more.

  • 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.' :)

    • @Boromäus Helms right now, i assume it needs disassembly, wireless charger from a dead phone.. maybe?

    • ...great suggestion! any idea how the batteries are charged as they are sealed?

    • Cylindrical Lithium Titanate cells would be perfect for maxing out battery and battery weight

    • Yep, just means he can add just under an additional 4kgs which is quite a lot of room, but not in volume... or you can adjust the starting internal pressure to calibrate the ballast also.

    • ​@Helveteshit Having more power doesn't mean you HAVE to use it and break Mach 1, with the joysticks I imagine you could control the speed for a slow exploration cruise but it's nice to have the extra speed when it's time to get it back to shore. I agree with the lights though,

  • Very cool project. Expect a call from the MOD 😄 Imagine, “Just a couple of syringes, RC components and plumbers fittings ! … and we’ve been spending how much on our submersibles?”😡🤬

  • 23:01 moment of truth, all that hard work really paid off, you know what you are motivating me to do something like this.

  • You could do is to get a radio with some more advanced mixing funtions, so you don't need separate pumps for strafe and rotate.

  • Awesome build! Interesting how you went with a ballast tank, feel free to check out our most recent submarine build, we made ours neutrally buoyant.

  • "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

    • @Daniel Donate that's what i thought! The front and rear ends, right?

    • @Gabriel Athero It looks a lot like Boba Fett's seismic charge.

    • Can't forget the shrapnel. 😅

    • OMG, I thought he said BONG which reminded me of Harold and Kumar in "Escape from Guantanamo Bay!"

    • hahahahaha, this made me cry... so true!

  • "Including the history of soap." That made me laugh. While it's probably an even further trek, there's a certain Loch that might warrant exploration.

  • what about modding the floater. making it bigger and add a solar panel to it to feed the batteries constant power to keep it up to power and greatly lengthen the time to use it.

  • Such a great channel! Love the way you facilitate your tutorials and seeing the vast collection of topics, I would like any recommendations on good iron soldering kit for startups. Thanks

  • very impressive how you put all this together.. it would be cool to make an artificial alligator with this... it would probably be a very sellable product

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

    • Isaque M - LT HoriZonT that's when you attract the 9/11 crowd.

    • imagine adding torpedoes

    • @Pompey Monkey Only if they're made of brass. 😉

    • @Ted McFadden Make room for the ICBMs! ;)

    • On the other hand, having those pellets as a reference, a revised version could carry additional things. 🤷‍♂
