When I was done watching this video I expected a channel with millions of subs and I was really suprised. This channel deserves more

It’s mindblowing how someone can accomplish this and not die

For all that is holy, if you're going with an open system, add manual weights you can disconnect 1 at a time for controlled emergency assents, and in the event of a full tip over from underwater currents, which can get surprisingly strong sometimes and they're basically invisible, you need to install enough supplemental air to breath during your assent to prevent getting the bends (or drown).. Just stick a divers chart inside next to your depth gauge so you can guesstimate your (safe*) climb rate. I presume you know this, but if you plan to go below 30ft, things can get life threatening (*from the nitrogen in your blood stream) *beacuse if you have to go back up too fast because you lack enough supplemental oxygen, you can still die. (I'd install 2 flags on the sides of the sub that read "Submarine In Distress" with perhaps some instructions on what you want them to do, with little LED strobes for visibility, and waterproof two of those keychain alarms so you're also heard, attach them to something that can allow them to float upright, and give them long tethers so you can manually pull a pin to release them to signal for help on the surface if you ever need to, this would provide a cheap and efficient means for rescuers locate you and even possibly pull your rig back up if the tethers strong enough, and then it'll double as a "WATCH OUT" signal whenever you're returning to the surface for boats. Cheers.. I'm about to go down this rabbit hole myself, but IDK about the open concept, then again I don't intend on going beyond maybe 100 feet (probably less).

First of all, congratulations on your maiden voyage, super cool and unique project you got there. But for the love of god, please don’t go out there alone. Most Scuba divers even without all the experimental things at work here, strongly prefer diving in buddy systems and that should be a nobrainer here as well.

I can't believe UKposts is only just now showing me this. Really cool! Slightly terrifying watching the water fill up like that internally though.

Seriously impressive, I'm looking forward to the future videos! Side note: It might be worth looking into some pony bottles for the two compartments as an emergency backup source of air to surface with.

Yikes! Yeah, seal the electronics with triple redundancy when it comes to the stuff that keeps you alive. Side project suggestion - find out how to remote pilot the sub for the dive/surfacing tests before live crew. Maybe an auto timer? Might not be a bad idea to set an auto timer to surface in case of getting accidentally knocked out somehow (outside hit, unexpected medical issue, etc.) and a backup 'air bags' to surface you in case that fails. Also, you and PeterSripol heading to Florida this month (or the next). One doing solar power above the water and one going below. Be careful not to bump into him from below!

Oh, boy. I wouldn't get into my own underwater diy projects without an emergency team that scoop me out when things go south.

Oh my god. From the thumbnail i thought it was a small rc vehicle. I was shocked that it's actually manned (and a two seater at that).

can i use this to go watch The titanic with 5 more people?, its for a friend

Watching him slowly going down and water rising in on him in a tight gap was giving me panic attack

Wow, you went out to test this thing with no backup help? OMG! This system works great but i dont wanna get wet and cold. But i understand why you went with this design :D

What in the heck do you have to do to get views on UKposts if this isn't it? This should have a million views minimum

You might want to consider pressure compensating your motors and electrical system. Mineral oil is non conductive. You fill the motors and any electrical boxes with mineral oil then run feeder hoses to a compensator diaphram. One side of the diaphram is closed and attached to the oil system while the other is open to the water. When you descend the water pressure pushes on the diaphram which pushes on the oil which is non compressable. This pressurizes the oil the same as the outside water so you only need o-rings and seals good enough to keep the oil and water separate and not to withstand pressure.

This is absolutely amazing. And great documentation of the project!

Underated Channel

incredible work!

I'm here because I went on hackaday looking for a breakdown of the recent sub, and came across a post about yours.

As someone toying with the idea of this pursuit, I really applaud your work. Nice job!

I searched for Stockton Rush and this video popped up on my feed 😂

Your knowledge is sublime 👌

Fascinating,great job.

3:24 I remember doing this in my bath, it was a amazing experiment. Keep it up! You made me get some inspiration!

Wow this is sooooo sick I am glad you never gave up on this dream!!

This is absolutely amazing dude

Wow! That's very impressive. I'd really like to know more about the CaOH setup that you were going to do for the scrubber. What did it look like and how much CaOH was there? I'd like to make a scrubber myself.

Very cool diy project! Can't wait to see some other dive videos.

You are crazy !! Brilliant work!

This is so sketchy but thanks for sharing your adventure with us.

Ive see all your videos..thats awesome..keep the great work..

Nice job and interesting concept with the semi-wet design. You should check out Hank Pronk and his sub. Might give you some ideas for V2!

holy shit I thought it would be a small rc one! massive props!

A diver i know watched this with me and they said that thing looks like a death trap. your a braver man then than them.

You have balls of steel sir.

This is amazing, looking forward for more videos about it

This video deserves much more views!

What does it have for safety features? Like "Get me up now!!!" or "Let me out!!!" type features :D

Cool mobl diving bell

so this dude made a 2 person seamoth :D nice work!

For an emergency system if the vehicle somewhat capsizes while bilging water, you could have a hose on a float that can be detachable to provide a secondary air intake valve that can float with it's own buoyancy system.

Well done - I applaud your ambition!

Very nice! Thank you!

Love the work! Huge motivation to start a somewhat similar project I've had in mind!! Please please lete know where you obtained the half dome/bubble windows?

Holy crap, Thats like $1,400 worth of resin. How was the fiber glass cost?

Damn man your kayak wet sub is cool, that's how I found your channel but this one is alot cooler to me, it's beautiful man! I totally get your reasons for wanting the smaller wet sub though, like you said, you can do a whole lot more and get to better spots. That being said, please also continue with this sub!..

10/10 Content, well done.

Underrated.

What kind of fiberglass shell did you use

Very brave man. What if this overturned and you couldn't get out of the hatch? Could you try making a hovercraft next time? 😁

Brave of you to dive in the Indian River lol. Last time I went swimming in there I ended up with an infection so bad I was in the hospital for 3 days

really cool, make more videos about submarines

Great video 👍

Oceangate has been real quiet since this dropped

THANK YOU FOR INTRODUCING ME TO THE MUSIC OF SERGE PAVKIN

Live footage of the titan sub minutes after its first desent have just been released. This engineer speaks on the limitations and design behind it

Another good point would be that an ambient submarine also serves as it's own diver chamber for decompression purposes. Should someone dwell at depths beyond the recommended dwell times one simply moves to a shallower depth and lingers for the recommended time before going shallower.

Do you need to install a CO2 scrubber to keep your breathable air free from contamination?

Super cool project, one of the craziest home built projects on youtube but, I really hope you’ll put more of an emphasis on your own safety if you revisit this.

Oh gee, I wonder why YT was suggesting this video to me NOW of all times. XD

"one of a few dozen working homemade submarines in existence" and the ONLY one not being used to smuggle drugs

Okay this Video got my sub!! And You got some brilliantly simple fixes!! 💯💯💯💯💯

How long do you recon it could last underwater before breaking or running out of air?

Wowboy ! I'm speechless...

you should get a camera with a wide angle lens, such as an insta 360 or gopro, would make the interior shots alot better!!

Nice video

What do you do if you have air pressure failure while submerged? Having a mechanical failsafe, being able to drop a counter-weight might save you from Davy Jones Locker.

Hold up, is this the little yellow submarine sitting in front of El Ambia in Downtown Melbourne? I saw the thumbnail and recognized it instantly.

You are talented

Seems exceptionally hazardous unless you have a way to blow the sub apart with squibs or automated surfacing equipment activated with a Deadman switch or a buddy to rescue you or a hole big enough to escape through or scuba gear inside to use for air in case a hole develops on top. Good luck.

Im suprised you dont have more folloers youll gwt there Keep the videos coming

True its like a Air Bell long ago that gave it's wearer air underwater even though it was open

great video

So, depth control via pressure is inherently unstable, right? As you go up, the air expands making you go up faster and faster. Likewise, as you go down, the air compresses, so you drop faster and faster. So, without some other system to stabilize, I think you basically can't stay neutral passively. (Closed submarines can close their ballast tanks, so I think they have less of a problem remaining roughly neutral as their depth changes.) Am I misremembering/misunderstanding? And assuming I'm not misremembering, doesn't that make this super hard to operate safely? In particular I'm not sure how you would do a controlled ascent while avoiding the bends.

I would love to build my own but I have no desire for it to be a deep water sub. I'd be perfectly satisfied with maybe 100ft

I love the batman tailfins

Ok, the picture of submarine The Kursk, made is even more scary to watch. Plus, I really hate the sea. But just because the sea isn't really my thing. I still you have a lot of talent to build this contraption; emphasis 'Trap' in that word.

Very interesting your submarine. I would have some many curiosities about some design features and reasons of your selection for A instead of B, and so on … May I suggest you post some more content, even your brainstorming and “working in progress” would be a pleasure to know about.

Yeah... but why? This has all the disadvantages of scuba gear, with a lot less mobility, visibility and safety. Impressive effort non the less. I think your dive kayak is a better idea. Though still not sure if it beats simply diving from a kayak.

How does pumping out the water eliminate the need for purge air. Seems to me that any water pumped out would be instantly replaced by more water coming in from below

Hey man, awesome stuff! Dont get me wrong this is an absolutely brilliant project, but to me it seems more like scuba diving with a scooter. Its just way more cool! Also: How do you deal with the CO2?

For what it is worth. The ambient submarine has much to provide that otherwise would go unnoticed. With sophisticated passive listening sonar capabilities it can offer a better understanding of the surface contact populous and intent that is more than simple divers can achieve. I too am pursuing an ambient submarine. My main reasons are easy egress should things go South and simple deployment and retrieval. A heavy r&d on listening and tracking sonar is a must. There is no better way to avoid collisions than to know where everyone is before you go shallow!

This would be a great channel worth subscribing if you actually did your follow up videos. 6 months and 1 year I can't find one for this video or the kayak sub one either. 😪 I was really interested how these worked out.

Impressive

Another area of interest is of course a periscope. I am using a seal rated to 300psi to ensure no air losses while training this scope.

Quick question, how do you calculate where to put stiffeners?

Not sure if you look at your comments but I'm also in Florida and am preparing to build my own submarine and was looking for clarity on registering it as a vessel

Brilliant.

Awesome

No way in hell would I trust anything I built myself to keep me alive underwater

awesome

Since subs are a hot topic you should send this unmanned send it till failure

Class!

What a legend

This channel needs more sub (I am sure this joke has been done already but hey)

What Cad software are you using? 2:31 that was caused by something else.

You might as well scuba dive. The point of a sub is to stay at 1atm. A wet sub is cool. I've been certified since 1980. I live in the Great lakes. I've done 100's of dives. I like your sub it's good for older people who will never dive. One thing , pay attention to your dive tabe! It just seems your asking for trouble. If it rolls over the party is over.

Hey buddy can we go see the Britannic?

❤

I really want to build something like this.

Any updates on the sub?
