I really like that you can see the balloon expand as it ascends--it really illustrated the instability of this depth control system, which scuba divers would likely be familiar with!

[@987654321tupac]

Yup. As you rise, pressure drops so you need to reduce the air volume in your buoyancy device (baloon in this case) to maintain neutral buoyancy. If you don't, your rise will accelerate as your positive bouyancy increases at an increasing speed and your sub shoots upwards (and could get the bends :-))

[@iantaggart3064]

Accurate. Getting to neutral buoyancy in SCUBA gear is a nightmare.

The thing is, submarines don't only use ballast tanks to control their submersions. They also have side fins for fine tuning. Also without automatic pressure controller it will be extremely difficult to keep steady depth. I still would give 10/10 for really cool project.

[@sando5943]

some subs only have side fins or wings and work like planes underwater, which would make a really cool lego build

[@johnineson]

@@sando5943 he's already done it, look at the previous attempts

[@AnttiBrax]

Side fins only work in motion. But the real difference is the displacement of the vessels. The margin of error is 1000000 times bigger (or around that ball park) on an actual sub so tiny changes have less effect.

[@ThePulmentinum]

Also this buoyancy system has the problem that its equilibrium is unstable: if it surfaces a little the water pressure lowers, the balloon expands and the submarine has more buoyancy, surfacing more. Opposite if it goes a little deeper, it wasn't to go even more deeper.

That idea with the balloon as the outer ballast basin is ingenious! With this you never run out of air supply in the hull!!!

[@ethanvalley1391]

You can add a ballast tank inside the submarine by replacing the balloon that pumps air in and out of the hull with a balloon inside the submarine that pumps water in and out of the balloon that's inside the submarine. This will allow you to; go deeper, be able to keep a stable depth, and not have to worry about the water pressure. (You may have to take out some lead pellets for more room) You could also put the go-pro (or some other camera) on the front of the submarine so that you can see where your going and explore the bottom. And if you're realy ambitious, you could add lego arms to allow you to grab items on the bottom. This submarine is very impressive and can be used to find things like; good fishing spots and valuable items on the bottom.

[@lego1591]

Only problem then would be signal strength. Didn't seem like he went too far and lost contact already. Would need a much stronger radio.

[@MadofaA]

@@elucid07 Yeah, of course youk’re right, but I was more refering to the submarine in the video. The reason he can’t control depth and get it to “hover” mid-water is the use of a compressible buoyancy tank (balloon).

[@nathanthof3652]

Super cool! Maybe you could try adding rotateable "wings" that generate lift? That way you could match the water density as closely as possible, or be slightly more dense, and go up by increasing speed/angle of the wings

[@pRahvi0]

The first thing I'd add would be an emergency surfacing system: A piece of (scrap) metal on the outside of the submarine bottom, held in place by a magnet or few inside the sub. There would be a motor (or better yet, a spring with a trigger) to retract the magnet from the proximity of the bottom to further inside, so that the piece of metal would drop off and the rest of the vehicle would surface even without the balloon. This mechanism would be triggered automatically after a certain time of no radio input (indicating lost connection) or if the outside pressure goes too high (indicating inability to surface by normal means i.e. the balloon).

[@aroraptor7550]

Or you could just make droppable weights

You need some compressed air in a seperate tank inside the sub. And another one. That one is filled with water at the Start. If you pump the water outsides, you can control the depth. And dont forget: your sub seems to be heavier, when it is slowly. So it will sink :)

[@stevevernon1978]

i still think that negative buoyancy at the start is a BAD idea. if you lose radio control, it STAYS DOWN. which is, as we see, BAD.

[@thanielsibula6189]

Unless the sub checks for radio contact at regular intervals. If it lose the signal, it can automatically start surfacing. And with that, the need for backup systems shows up. So an internal tank for water, that is blow over board with an internal tanks pressurized gas, and thus even with ballast, the sub should be positively boyant to begin with.

[@HTacianas]

@@Thomas_Bergel The concern with a safety line, as we saw in the video, as that since you can only pull on it in a single direction, it's very easy for it to get caught on debris. I'm definitely in agreement with starting with a slightly positive buoyancy in order to prevent accidents.

Brave to use an unprotected latex balloon right next to a propeller and go diving in a natural body of water full of rocks and sticks. If that balloon popped you'd never be able to surface. Looking forward to seeing what you come up with for the next Lego submarine.

[@harbingerofwarx995]

I don't think there's nearly enough pressure in the balloon to make it easy to pop. Wall thickness is determined by how stretched out the sides are, and a balloon only a couple inches inflated is going to be much stronger than a typical size of balloon. It will also have more deflection and less outward force when something touches it, which will absorb impacts. The propeller might even be stopped if it impacted the balloon as it can't support much torque.

[@clonkex]

I was more worried about how much further it inflated upon surfacing, as the water pressure decreased.

[@erikmeer]

Great to see your creativity at play! Depth control is indeed difficult to regulate because of the balloon: When the inflated balloon goes up in the water the pressure will reduce, balloon will become larger and therefore adding buoyancy. Same goes for going down, when the inflated balloon goes down in the water the pressure will increase, balloon will become smaller and therefore lowering the buoyancy. It is more an on/off kind of depth control. In Submarines they solved this issue by fixing the size of the buoyency control tank (steel tank) and adding water / removing water. Because of the fixed size of the buoyancy control tank they can have fixed depth control.

[@TheREALMcChimp]

See submarine 1.0-used a plastic syringe as ballast. This is more like what scuba divers do with BCDs and drysuits-in that case it works because the diver can react very quickly to changes in bouyancy by controlling their breathing, essentially using their lungs to trim the balloon.

Hey, you found my bike, 10:40 was wondering where i'd left the thing!

[@Pscribbled]

I’m surprised your radio controller worked for such depths. Very cool

Easily one of the coolest channel’s here on KZbin. One day we’re all gonna get in trouble using one of these lol

When you used "+" and "-" to show magnet polarity, at least 10 physics teachers died XD

i understood it but I didn't noticed what was wrong ... lol and i am studying for mechanical engineering....

[@jeremiahdavis7904]

Actually, its not uncommon to refer to magnets by +/- orientation, where N=+ and S= -

It's amazing!! Love how the fish got curious 😂

Amazing job there you've done
