@@Project-Air The simplest way to eliminate water slosh upsetting the balance is to fill the water bottle with sponge. It will absorb the water and what does pool in the bottom won't be able to move fore and aft.

This is so cool. Was thinking a lot about building an FPV sub. And I run into same problems with water and data transfer in my head. I would try and just expose antenna to the air on a really small and light floater using very thin wire. Tangling could be a problem in that case, so I thought about some sort of antenna wire tension/retraction system. Not sure if there are antenna wire length-related problems, tho. Also, 3rd motor oriented to up/down axis and with some pitch control would give it much more maneuverability and control in tight spaces. And could compensate for most of the boyuancy problems.
The collab I didn't realize I needed in my life! Awesome content between the two of you. I love how the two of you approach the challenge so differently.
To see how a simple design can succeed is amazing. Thanks. And you can prevent the water tilting your bottle by prefilling the bottle with cotton wool. Wishing you great success with future plans and your channel.
Great video! Add a 'trailing floating wire antenna" for the RC TX/RX. Make it buoyant and long and some portion of it will float on the surface, even when at depth. (BTW, That's what real submarines do)
@@nou5440 I've seen some experimentation for ultrasonic used for communications so I'm definitely curious if that would work reliably in their small creeks/ponds
Great work! Really interested to see if you find any success with the low frequency stuff. I've heard you can "potentially" get up to 30-40m in fresh water for basic controls with the right conditions at 27/40mhz. Video transmission may prove to be much more difficult or perhaps simply limited by bandwidth and/or physics, but I'd love to see your results regardless! (btw there's no link to Matt/DIY Perks video in the description as of writing this comment)
Ive Watched lots of these kind of vids But I've never seen someone so entertaining the sad thing is not that many people watch him as he deserves Respect to this man keep up the good work 💪
Very cool project! I love the underwater cameras because the of the shelf ones are so expensive. A bottom scouring drone finding buried treasures seems appealing to me. Nice work as always.
If you want it to go deeper tan a meter or two, it will need to be tethered. Or you could use something using sound as a transmission medium, but I don't think a lot of people managed to do that... Great job
Immediately after watching Matt's video I came to your channel, didn't see any thing related😞, since then I've been expecting yours. This is very nice, expecting a 2nd part.
I love this video would love to see you improve for deeper dives and more controllability. Would love more details on the build also so I could build myself at home.
The trick to low frequency data transmission ( for the video ) is that you have to broadcast the data over a spectrum of frequencies because the max data rate will always be frequency/2. So basically you end up transmitting 1/10th of the data on each frequency, but you transmit on 10 different LF frequencies and recombine the signal at the receiver. I don't know for sure, but I think that the Navy uses a lot LF transmissions for underwater coms.
Humm... I didn't thought about the sloshing water, I did for the cable, it was huge. Some notes. For water sloshing, have you considered using foam or a more dense than air material that can be fixed? I also thought about peristaltic pump and a bladder for better buoyancy control, for Diy perk's sub, turns out I wasn't analyzing his project correctly again. On communications, a thin USB cable could be a decent tender. However I would consider just a long antenna cable attach to a buoy. My thought being, just use a long wire, however it has problems with impedance, so just a long coaxial cable sound safe to me. If only submarines weren't expensive, a relay fleet sound like fun headache.
I like the idea of the floating antenna. Indeed coax cable will be needed. But for sure: waterproofing a cable will be a challenge. Even in military size subs they still have a challenge in communication
Doesn't at all surprise me that Matt's solution was completely over-engineered. But, then, that's why I love his channel. Your solution, whilst definitely simpler, was still great.
I think the problem with using a water bottle as a ballast is that the submarine design isn't always going to be level, unlike DIY Perks' design which doesn't pitch forward or back. With yours, once you pitch forward or back, the water will go to the furthest point in the direction your pitched in, making it really difficult to pitch the other way. We could see that when you tilted your sub down, it never levelled out again. This wasn't a problem with DIY Perks, as his submarine was designed to be symmetrical, meaning it's CoM is in the middle constantly. If it was to tilt in a direction though, it'd probably be able to recover, as his has two dynamically weighted ballasts, meaning it could go back to the surface and level out, or make one side lighter than the other to level out and then equalize the weight once level.
Keep it up with the sub content. I have been working on the design for mine for awhile and love seeing it on UA-cam. All of the off the shelf subs are junk and really intended as toys.
I used to race sailboats around flags on lakes. To keep the flags in one place we built them with a concrete anchor (plastic jug with a handle filled with concrete), and tied a 10 feet (roughly 3 meters) of polypropylene rope (the yellow stuff) to the anchor. The flag was 10 feet of 4-inch PVC pipe sealed at the bottom but with a hole for an eye bolt. We tied 10 feet of polyester rope to the pipe. The pipe was partially filled with sand so it would bob in the water with the flag end up. Polyester rope sinks to keep from fouling boat propellers and rudders, and polypropylene rope floats (to keep from fouling on the bottom of the lake). The rope in the middle didn't matter as much. So if you wanted to make a floating marker tethered to your submarine, you could do something similar. Below 10 feet deep there's not much to see until you get to the bottom. Adjust your rope accordingly. Our lake was 130 feet deep near the dam, so we needed about 200 feet total for our purpose.
>Change your bottle with wide open cap, >Put your electronics inside that bottle, >Use air balloons and sand packets for correct buoyancy and leveling.
Hmm, as an alternative to completely filling the main bottle with water, fill it so it is neutral then weigh that water. Mix up some epoxy to that weight and put THAT in the water bottle (sitting level). Once the epoxy cures it won't be moving. Then you could probably use smaller syringes for trimming the buoyancy. You could also make a 1 or 2 meter long 4 wire tether going to a foam float with the antenna for the RC and FPV mounted on the float.
Great project! How about a simple floating pod with all the avionics (2.4GHz ok :) - then a long _thin_ umbilical down to the craft? This would be similar to the Nemo dive system - a 9m deep battery powered scuba system - only it uses an air pipe instead of the cable :-) The craft should easily pull the pod along.
Hey please do a part two. I know im kinda late writing this but hear me out. Ive got some ideas; - Put all the electronics inside fore a more hydrodynamic body because you will still be able to move center of gravity around and by sticking everything with velcro to a big sliging platform you will be able to make fine ajustments and still be abe to reach to it wheen troubleshooting. - Cut the cap of so you only have half of a metal bottle and 3d print a big lid mith hydrodynamic form. - And make the big cable smaller by using a ethernet cable and choose a light and flexible one. The batteries for the motors can be stored inside for more weight - The syringes should remain for balancing I hope you will read this and let me know what you think of these ideas Love your content
Aha! well it's good to see the companion video. I came in from the DIY Perks video. Great builds both. I'm amazed at how you waterproofed the RC gear, I've not seen that done before. Although DIY Perks' sub is a bit 'pro' in comparison, I really like your sub too because it looks a bit more within reach of my skills. Nice job, thanks for sharing.
This is Awsome. Just recently discovered your channel. Great vids over all. Impressive. Im really looking forward to the next video involving some kind of rocket engine
On board power with a very light tether (cat6) seems to work best. Add weights/foam nodes on the tether to make it neutrally buoyant. Another option that might be cool for control (not video) would be to play with a sonic pulsing transmitter/receiver set up and a light weight video cable. I think combining the two set ups would be ideal though. A light weight, neutrally buoyant control cable connected to a float which has radio on it so the cable would be for depth only. I love the VR helmet set up. I would add a heavy fishing line (In the U.S. we hall it 80 pound test) tether to the float for easy recovery. For power look into the tubular battery packs some cordless tools have. I wold also mount the two main motors on the fin controllers you originally had so you can change the pitch to look at something with out moving from where you are. I love the video and wish I could do things like this myself. Thank you.
Although Mats sub looks more sophisticated and closer the real submarines, your idea is simpler and cheaper to build ....which is amazing... plus, the size of your submarine is quite small.
Great project! I wonder if you could stuff the bottle full of bits of torn up sponge so the water won’t be able to slosh around and is just absorbed into the sponge.
I was waiting for this video after seeing the one over at DIY Perks, and well it does not disappoint. Hopefully you can get a better receiver/transmitter situation going on so you can really stretch the legs on this beauty.
If you fill the bottle with a granule material it might help with the sub's balance. The granules/particles will occupy the volume of the bottle but the spaces between them will be occupied by air making it stable to changes in pitch
