@@spacegamer6906 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).

Building a space worthy craft is easier than a deep water craft, it’s getting the craft where it belongs that makes space travel so much harder than submarine travel.
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.' :)
@@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,
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.
@@alkaupadhyay7650 Sure th-cam.com/channels/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!
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
I was just going to mention that. I remember having AM and FM radio control gear back in the 90s and 00s for cars and airplanes. While obviously not as stable a signal as 2.4GHz, an AM system would likely work quite well underwater! 👍🏻
I suppose with that solution it would work even better if the the antenna from he steering unit would be submersed too? It would eliminate the signal losses when transferring from air to water? Don't real submarines have any specific antenna configuration to communicate with the external world? If they have such methods, they most probably will about never be allowed to use it when doing their sneaky business.
@@tuttebelleke US and Russian military submarines can receive when submerged, other nations need to surface to communicate. A careful scan of the surrounding sea is needed before surfacing and they use high frequency tight beams aimed at satellites. The ultra-low frequencies used to transmit to submerged submarines have wavelengths measured in kilometres, so the transmissions come from aircraft trailing cables several kilometres in length as antennae. It is possible to build ground stations close to shore, but they are easy targets because of the huge and fragile antennae so aircraft are used instead.
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!
If he gets an RC flight controller for quadcopters, it could easily be programmed to do both 1 and 2 automatically with the same controls he is using in the video. It can be set to have the left control stick left/right activate the opposite side thrusters, and the right stick left/right can have it turn the rotational pairs go automatically. He is already on 2.4 GHz too, so as an ecosystem it would make sense. I was already coming here to suggest brushless motors/propellers but his associate in the video already suggested it. These extra things don't cost him anything but money as well, since he has so much ballast in there already since it's huge.
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.
Or he could keep perhaps keep both sets of pumps for extra flexibility, that way you get the flexibility to use both sets of thrusters just to turn or translate if you want to also.
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!
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.
Damn man, am an engineer and i rarely get impressed by TH-cam's DIY projects, but almost all your projects impresses me, like in this the way you modified the servo is simply genius!
We have no idea how he knows how to do this, or how he planned it. He claims he made it up as he was going, but that seems completely improbable to me.
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
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.
It's a slippery slope. I also thought "I could make this if I had a soldering iron". Later I bought one. Then I thought "I could make this if I had a rotary tool". Ended up buying one as well. These days my go to excuse is "I could build this if I had the parts and materials". I refuse to buy electronic components and sheets of brass so that I don't lose that one. I'd rather blame the lack of resources than accept the lack of skill.
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.
make the float for the antenna more buoyant than the sub has weight with full ballast tanks under water. that way it can't pull the float down and you don't need some complicated emergency system
"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
Excellent build! I'd love V2 to have more speed (rear prop?) and an element of hydrofoil control. The water pumps looked quite weak and I'm not sure you could maintain control in moving water like the sea. My instinct is that significant forwards motion combined with hydrofoils should allow you to quickly change depth by moderate amounts without actually changing the boyancy syringes.
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 ;)
Most recent rc transmitter have a failsafe option which can set a servo to a desired position if signal is lost. In his case he could set it to empty the ballast.
@@Runescapeluvr4 27MHz should work well. I would recommend checking if that band is legal to operate in your country as it varies depending on where and what you're using it for.
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.
Another issue with trying to achieve neutral buoyancy before submerging is that the conditions of the water will greatly affect how much needs to be displaced to be considered "neutral". Things like temperature, salinity (salt content), and pressure will limit just how deep that submarine can go and how well it performs. In particular the sub's inability to regulate the pressure of the air inside its ballast tank will make it so either there's a maximum depth to which it can descend; or if it _can_ go deep enough, it'll result in the ambient water pressure being so great it compresses the air inside more and more as it sinks to the sea bed like a rock. The latter would be a somewhat greater issue for DIY Perks' submarine as it relies exclusively on the pressurised ballast tanks for buoyancy where ProjectAir's vessel will be able to counteract somewhat by using the propellers and fins to orient itself vertically and push itself back up. Submarines are complicated, yo.
@@notean That would complicate things a bit though. A simpler solution would be to add additional servo to control the two syringes separately, and being able to ballast forward and aft independently. Though suspect a combo of channels on the remote and/or space / weight restrictions might rule that out.
@@TheZirMc IMO it would make things more complicated as you must constantly compute pressure of tank1, tank2, depth and desired angle . It is possible to with computer controller but not simple. You must constantly fiddle with 2 motors to get balance. In my way you can set/freeze depth and set/freeze angle separately.
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.
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.”
@@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.
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!
It was cool to see this actually work in the end. The only thing I ever managed to build from your channel was a wireless Bluetooth speaker but I want you to know that your content is deeply inspiring. Please keep making beautiful and awesome stuff.
"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
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 :)
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
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!"
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.
Still after 2 entire years I am still waiting on the revision of this project. Hoping we see it some day soon. I'd like to see what big improvements can be made after all this time
I tried something similar last summer, but i used an ikea plastic box and a peristaltic pump to fill a small tank inside. It seemed perfect because it was fully sealed and easy to drill ports in it, but as soon as it was unerwater it would be deformed by pressure and lose more buoyancy than it should... And so i learned why submarines aren't rectangular and made of thin plastic.
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.
4kg of batteries is a lot of batteries lol. Would have to add anothe half meter to do that. But that half meter would add more bouancy so more batteries would be needed again. And so on and so forth. The thing would be 5 meters long.
This is pretty neat. I would probably remove some of the steel ballast and add some more batteries instead for extended runtime as there are quite a lot of devices in there. Also 'low power' should probably trigger the ballast tanks to purge while it still can.
absolutely amazing! The moment the submarine went down and up, went forward en backwards, I genuinly was as excited as you were. Thanks so much for this DIY Perk.
As always, this is brilliant engineering. Just a quick comment -- couldn't it be reformatted as three parallel tubes to be more compact? Two ballast tubes and a control/camera/thrust tube in between them?
Additional cross-sectional area dramatically impacts a submarine's performance moving through the water. While it would make the arrangement more compact, it would dramatically impede forward motion by doing so. It's a good thought, though! Never stop questioning what's possible, as it's the only way we can develop.
"buoyancy relies on the weight of the object being less or equal to the weight of the water it displaces" why couldn't my teachers all through highschool and college explain it like that? Literally INSTANTLY understood exactly how it works after being slightly confused by the concept my whole life.
my physics professor last semester explained it by giving us formulas and then throwing word problems at us and having us figure it out, worst professor i've ever had
@@stevep250 I was lucky, I got a cool teacher who was both good at teaching and also funny. I did quite a good bit of learning thanks to how he explained stuff like that in ways that made sense for my stupid 18 year old brain.
You had some odd teachers. That’s the easiest way to explain it. Then you throw the Archimedes principle in and you’re basically done. I’ve never heard it explained NOT like this.
1:20 Most subs actually remain at neutral buoyancy all the time when under water and instead use dive planes to 'fly' the sub underwater. Only going to negative buoyancy for a crash dive and positive for surfacing.
3 ปีที่แล้ว +2
Yea a maneuverable sub will have planes for control, a more scientific exploration sub will have thrusters that can doe the same thing to maintain station keeping. Buoyancy alone and on a small scale is not that stable. But yea you do need to get the boyancy rigth, even the biggest subs are "trimmed" as its called for nutrual buoyancy but maneuvers are done with planes or thrusters. I think some pods for station keeping should help. Also I think one can reduce the pumps by half, no need two have 8 pumps, 4 for pushing it sideways and 4 for rotating it, a mixer could be used to mix the signals to make it do both with only 4 pumps. Also that can be reduced to 2 if one uses a prop in a duct instead that can run in reverse. Im impressed by the subs but if he wants to improve on it and make it more stable and simple this could be one way to do it.
awesome! Arm Chair Upgrade Ideas: 1) add some floats to the cable to help keep it slightly buoyant/ very buoyant just above the sub. This may help keep the cable above the sub and prevent it from wrapping around any of the jets. Also maybe consider testing the strength of the cable you are using/how strong it is attached to the sub. It's probably fine, but adding an independent cable with it's own structural attachment point might open the door to you being able to do some really fun stuff. 2) Take a page from James and add dome higher def cameras to you rig. I'm sure you can make a whole video just about that and salvage some cameras from cell phones or something lol. 3) I think you need to add sonar.
I saw that the current setup is very sensitive to the setting of the syringes. This is quite logical, as the overall density of your submarine should be exactly that of the surrounding water to stay at a constant depth. What you could do is program a PID (or PD) controller and a pressure sensor somewhere on the body of your submarine. Then you can use your controller to set a depth (by setting a pressure). This will increase the ease of use of your submarine. (However, it will also add some complexity and weight to your submarine. As you need to add so much weight, it will probably not be that much of a problem.)
Honestly, he's one of my favorite TH-camr.. his honesty with all the fault done during the project not only shows his humble attitude, but also helps viewers to learn along the way. Keep the cool attitude, Matt. And most importantly, with crazier projects next. Always will watch out for u.. ciao.
This so appealed to the kid in me. Back in the day, I would have killed to have something like this to go exploring the ponds and streams where I lived. I especially liked that it was all stuff you could get from local suppliers with little modification. Thanks for sharing this.
My kids must NOT see that video, they would harass me until I make a DIY submarine. This is an awesome project, your creativity and problem solving ability are both impressive! 👏👏
Fascinating! Makes me wish I hadn't given up my R/C flying 10 years ago. Subs would be a good transition for people with aging eyes who can no longer see distances as well as they used to. Question: Once your technology has been proven, might it be possible to troll a smaller floating antenna tether rather like the way real submarines do for satellite comms, air inlet and diesel exhaust? As long as the antenna floats close to the surface the sub should receive signals without difficulty. That would allow the sub to travel further from shore without it being held back by all the wires. A small GPS module could then be added to help the sub find its way home automatically in the event of low battery, loss of signal or limited internal failure.
You could ditch all tethers and use sonar. You just need a long antenna. Like how Air Force 1 communicates with subs that are fully submerged. They just use a 2 mile long antenna.
Love this channel and both designs! ProjectAir's design takes great advantage of not having people aboard with amazing diving speed and underwater navigation while DIY's design is more stable and well suited for under water observation
Ever since playing Subnautica, I Crave exploring the deep unknowns. Even just cruising about underwater (Cyclops anyone? Sea Moth?). Amazing as always! Man, this also gave me an idea to make a simple mini battery powered propulsion device to get my fishing line with bate out into the ocean without swimming, or drones or anything.
How do you even come up with these designs? Its one thing to have ideas and a completely different to implement them. You not only come up with awesome ideas, you have the knowledge and skills to give life to them too. You have it all planned out. What materials to use, where and how to connect everything, what would work and what wont. So much planning and such a keen eye to details. That too in such short time and to make time to shoot and edit a high quality video of it. A superhuman achievement. Awesome work as always.
Oh, finally someone built such things, When I was 10 (now I am 50), I drew several design very similar to this. However I didn't have those tools to build this. thanks , great job. I will follow your design to build one, after I have money to buy the 3d printer

@@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,
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.

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
+1 When I saw the flysky come out, I was expecting a loss of craft at some point :)
lower frequency have better range under water so it would be best to use the lower frequency possible
I was just going to mention that. I remember having AM and FM radio control gear back in the 90s and 00s for cars and airplanes. While obviously not as stable a signal as 2.4GHz, an AM system would likely work quite well underwater! 👍🏻
I suppose with that solution it would work even better if the the antenna from he steering unit would be submersed too? It would eliminate the signal losses when transferring from air to water? Don't real submarines have any specific antenna configuration to communicate with the external world? If they have such methods, they most probably will about never be allowed to use it when doing their sneaky business.
@@tuttebelleke US and Russian military submarines can receive when submerged, other nations need to surface to communicate. A careful scan of the surrounding sea is needed before surfacing and they use high frequency tight beams aimed at satellites. The ultra-low frequencies used to transmit to submerged submarines have wavelengths measured in kilometres, so the transmissions come from aircraft trailing cables several kilometres in length as antennae. It is possible to build ground stations close to shore, but they are easy targets because of the huge and fragile antennae so aircraft are used instead.

Using... you guessed it; brass!
ha ha ha ha good one :D
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!
Underrated comment, u could make a lily pad nuke!
(Sorry I spend too much time in the r/Kurzegesagt subreddit XD)
If he gets an RC flight controller for quadcopters, it could easily be programmed to do both 1 and 2 automatically with the same controls he is using in the video. It can be set to have the left control stick left/right activate the opposite side thrusters, and the right stick left/right can have it turn the rotational pairs go automatically. He is already on 2.4 GHz too, so as an ecosystem it would make sense. I was already coming here to suggest brushless motors/propellers but his associate in the video already suggested it. These extra things don't cost him anything but money as well, since he has so much ballast in there already since it's huge.
Now you're ready to go visit the Titanic.

Yes
I think the steel pellets are used to make it easier to adjust the weight distribution to keep the submarine level etc
@@ramdom_player201 the buoyancy balance can be adjusted using the syringes on each end.
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.
Or he could keep perhaps keep both sets of pumps for extra flexibility, that way you get the flexibility to use both sets of thrusters just to turn or translate if you want to also.
I second this. Was just about to suggest the same, although my vocabulary wouldn't be as sophisticated 😅
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!
11:00 you don't need separate thrusters for rotation and translation, this can easily be achieved through channel mixing in your radio.

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.

Excellent build! I'd love V2 to have more speed (rear prop?) and an element of hydrofoil control. The water pumps looked quite weak and I'm not sure you could maintain control in moving water like the sea. My instinct is that significant forwards motion combined with hydrofoils should allow you to quickly change depth by moderate amounts without actually changing the boyancy syringes.
Yeah, the prop would be way more power efficient and faster than a thruster motor.
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
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 ;)
Do you think a 27mhz radio would work better?
Most recent rc transmitter have a failsafe option which can set a servo to a desired position if signal is lost.
In his case he could set it to empty the ballast.
i have a feeling that would make it much more challenging to get the live video feet at a good resolution
@@Runescapeluvr4 27MHz should work well. I would recommend checking if that band is legal to operate in your country as it varies depending on where and what you're using it for.
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.
Another issue with trying to achieve neutral buoyancy before submerging is that the conditions of the water will greatly affect how much needs to be displaced to be considered "neutral". Things like temperature, salinity (salt content), and pressure will limit just how deep that submarine can go and how well it performs. In particular the sub's inability to regulate the pressure of the air inside its ballast tank will make it so either there's a maximum depth to which it can descend; or if it _can_ go deep enough, it'll result in the ambient water pressure being so great it compresses the air inside more and more as it sinks to the sea bed like a rock. The latter would be a somewhat greater issue for DIY Perks' submarine as it relies exclusively on the pressurised ballast tanks for buoyancy where ProjectAir's vessel will be able to counteract somewhat by using the propellers and fins to orient itself vertically and push itself back up.
Submarines are complicated, yo.
Better solution would be single buoyancy tank and move-able ballast section which will auto-balance vessel as it goes.
@@notean That would complicate things a bit though. A simpler solution would be to add additional servo to control the two syringes separately, and being able to ballast forward and aft independently. Though suspect a combo of channels on the remote and/or space / weight restrictions might rule that out.
@@TheZirMc IMO it would make things more complicated as you must constantly compute pressure of tank1, tank2, depth and desired angle . It is possible to with computer controller but not simple. You must constantly fiddle with 2 motors to get balance. In my way you can set/freeze depth and set/freeze angle separately.

I tried something similar last summer, but i used an ikea plastic box and a peristaltic pump to fill a small tank inside. It seemed perfect because it was fully sealed and easy to drill ports in it, but as soon as it was unerwater it would be deformed by pressure and lose more buoyancy than it should...

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.
...und once the battery level is drained the submarine gets back to its floating home base (like an electric lawnmower) for recharging.
@@a.nickol6559batteries don’t change weight when discharged, is that what you meant?
4kg of batteries is a lot of batteries lol. Would have to add anothe half meter to do that.
But that half meter would add more bouancy so more batteries would be needed again. And so on and so forth. The thing would be 5 meters long.
@@nicholasfaber9695It’s talking about adding a sensor so when the battery’s reach like 5% the submarine will go all the way up to be recharged.
This is pretty neat.
I would probably remove some of the steel ballast and add some more batteries instead for extended runtime as there are quite a lot of devices in there.
Also 'low power' should probably trigger the ballast tanks to purge while it still can.
oh boy... this video about to get a surprising new wave
absolutely amazing! The moment the submarine went down and up, went forward en backwards, I genuinly was as excited as you were. Thanks so much for this DIY Perk.
As always, this is brilliant engineering. Just a quick comment -- couldn't it be reformatted as three parallel tubes to be more compact? Two ballast tubes and a control/camera/thrust tube in between them?
Additional cross-sectional area dramatically impacts a submarine's performance moving through the water. While it would make the arrangement more compact, it would dramatically impede forward motion by doing so. It's a good thought, though! Never stop questioning what's possible, as it's the only way we can develop.
Not to mention that the two ballast syringes in series will give pitch control if operated separately
Isn`t that the standard configuration on RC subs?
I`d check, but I can`t be bothered, hehe.

"buoyancy relies on the weight of the object being less or equal to the weight of the water it displaces" why couldn't my teachers all through highschool and college explain it like that? Literally INSTANTLY understood exactly how it works after being slightly confused by the concept my whole life.

This can be used for small scale ecological projects to monitor aquatic flora and fauna in a non-invasive manner! Excellent job!
I would honestly love a full video of just feed from the submarine. This was so fun!
1:20 Most subs actually remain at neutral buoyancy all the time when under water and instead use dive planes to 'fly' the sub underwater. Only going to negative buoyancy for a crash dive and positive for surfacing.
Yea a maneuverable sub will have planes for control, a more scientific exploration sub will have thrusters that can doe the same thing to maintain station keeping.
Buoyancy alone and on a small scale is not that stable.
But yea you do need to get the boyancy rigth, even the biggest subs are "trimmed" as its called for nutrual buoyancy but maneuvers are done with planes or thrusters.
I think some pods for station keeping should help.
Also I think one can reduce the pumps by half, no need two have 8 pumps, 4 for pushing it sideways and 4 for rotating it, a mixer could be used to mix the signals to make it do both with only 4 pumps.
Also that can be reduced to 2 if one uses a prop in a duct instead that can run in reverse.
Im impressed by the subs but if he wants to improve on it and make it more stable and simple this could be one way to do it.
This dude just sets better and better standards, it's amazing how good his projects are.
You should make an emergency surface system, where if the Internal pressure reaches X, the syringes start to quickly empty.

Arm Chair Upgrade Ideas:
1) add some floats to the cable to help keep it slightly buoyant/ very buoyant just above the sub. This may help keep the cable above the sub and prevent it from wrapping around any of the jets. Also maybe consider testing the strength of the cable you are using/how strong it is attached to the sub. It's probably fine, but adding an independent cable with it's own structural attachment point might open the door to you being able to do some really fun stuff.
2) Take a page from James and add dome higher def cameras to you rig. I'm sure you can make a whole video just about that and salvage some cameras from cell phones or something lol.
3) I think you need to add sonar.
I saw that the current setup is very sensitive to the setting of the syringes. This is quite logical, as the overall density of your submarine should be exactly that of the surrounding water to stay at a constant depth. What you could do is program a PID (or PD) controller and a pressure sensor somewhere on the body of your submarine. Then you can use your controller to set a depth (by setting a pressure). This will increase the ease of use of your submarine.
(However, it will also add some complexity and weight to your submarine. As you need to add so much weight, it will probably not be that much of a problem.)
Honestly, he's one of my favorite TH-camr.. his honesty with all the fault done during the project not only shows his humble attitude, but also helps viewers to learn along the way. Keep the cool attitude, Matt. And most importantly, with crazier projects next. Always will watch out for u.. ciao.

and I took that personally
Fascinating! Makes me wish I hadn't given up my R/C flying 10 years ago. Subs would be a good transition for people with aging eyes who can no longer see distances as well as they used to. Question: Once your technology has been proven, might it be possible to troll a smaller floating antenna tether rather like the way real submarines do for satellite comms, air inlet and diesel exhaust? As long as the antenna floats close to the surface the sub should receive signals without difficulty. That would allow the sub to travel further from shore without it being held back by all the wires. A small GPS module could then be added to help the sub find its way home automatically in the event of low battery, loss of signal or limited internal failure.
You need to try fpv and freestyle drones.
I've considered designing a ultrasonic-based controller where you place a transmitter on the water surface and a transceiver on the sub.
You could ditch all tethers and use sonar. You just need a long antenna. Like how Air Force 1 communicates with subs that are fully submerged. They just use a 2 mile long antenna.
