Use me as a dislike button, I hate how YouTube has removed the criticism feature

[gabrielferreira-puep]

interesting timing from the youtube algorithm

[evandiliberto]

The RC test flight style sea shanty was a highlight of the day, thank you

[SteveRogers]

This is the third DIY submarine video I’ve seen today, but it’s easily the best. Not only is it the most practical cost wise, it’s also the most functional.

[sherizaahd]

Ah, the faux shanty! "Tested minimally" is my favorite!

[shemp]

The best part of microcenter is that you can check on a item and walk out with it in hand. A bonus is NEVER WORRY about receipt as they keep records. And have tested this. Great store.

I worked with one ROV when I was a professionnal diver. The ROV was slightly positive and a motor on top would make it go down or boyant (or neutral). If the ROV failed and was out of electricity, it
would come up to the surface because of its positive boyancy. It worked very well .

I made a similar ROV about 5 years ago using regular RC airplane parts. You can use a flight controller for stabilized autonomous operation, SBUS, etc. I used a modified scuba regulator, one of those small spare air tanks, and a pressure relief valve to make an automatic pressurization system which enabled the ROV to go 329 feet deep without any problems. The possibilities are endless. The one drawback is that you will need a thin antenna wire attached to the ROV with a small surface float and antenna so that it can use GPS for autonomous navigation, video, and PWM/SBUS signals. What is really cool is that one can send regular radio signals for a short distance underwater, allowing you to use a camera without penetrating the hull of the ROV with the camera wire. This only works for a very short distance. If you want longer distances, you have to use low frequencies which will immediately draw the attention of Federal authorities which strictly control such frequencies for military submarines.

You can fly underwater with an ROV just as you can fly in the air with a quad or plane. In fact, it is actually better because there are few if any restrictions so far. But, I have to caution everyone that the government is aware of just how dangerous such technology can be in the wrong hands.

Hey Peter, I noticed some flickering in the video feed when you were toggling the controller switches. That is probably due to the way you wired the signals to the relays. The ethernet cable has 4 differential pairs. Because the video ground isn't isolated there is crosstalk that will increase with the cable length when ever the switch state changes. This is due to an induced magnetic field along the wire from the current to switch the relay. There will be a voltage spike in nearby wires. If the wire gets long enough the voltage spike may damage the video camera or display circuit. A better circuit that would take advantage of the differential pairs and isolate the video lines is possible. It is still analogue and cheap. You need double pole double throw switches and four diodes per relay. Each switch uses a coupled wire pair in the ethernet cable, leaving one pair for the video. If you are interested I can figure out how to send you a schematic.

That ended as abruptly as Oceangates Titan once you mentioned the titanic 😂

@PeterSripol I work on long distance ROV tunnel inspections in GPS-Denied environments. You are right on track with your PVC made vessel, but if you used some Fiber cable you can have two way communication the whole time along with more sensors, INS/DVL depth sensors and whatnot. We mainly inspect penstocks (giant tunnels) of hydro electric dams.
Anywho, cool video and ur on the right track, that is how an underwater ROV should look, like an ugly box with thrusters and as much room for different equipment as possible like Sonar and underwater LiDAR in high vis water

Just as I'm finishing up my DIY Sub build, Peter drops this! 😮 Guess it's too late to copy these sick sub building skills now 😖😛

Shout outs from Thailand - researching Underwater ROVS is one of the things that helped my beat my 2010 doldrums (and by doldrums I mean mid life crisis depression, natch) - and got me into electronics and robot stuff after years of VFX, aka CPUs and Computer screens. Always love your approach and your ability to take massive amounts of planned chaos and send it home. Thanks for this reminder - reminds me of some foundational times, and finding new passions. Cheers, man - keep it up

[morkovija]

Gotta love when Peter uploads. Improved the day right here!

[GavinGruys]

We had a program in middle school that was exactly this. It was a ROV championship between the schools in town. It was honestly really cool

[mrfrivolusfr]

the wellerman adaptation had me freaking out just listened to that song recently

[PunakiviAddikti]

A tether is pretty much always required to pilot these ROVs. Something interesting to try would be to use a buoy with antenna and a tether cable going down. That way it would be half-wireless.

I lost my favorite leatherman kayaking in my local lake over the summer. I was toying around with the idea of building one of these to recover it. Now I have no excuse not to! Great video, thanks!

[RepeatedFailure]

This will help so many people who suffer from chronic boating accidents!👀 Thanks Peter!

PS, I dig the rctestflight-ish shanty

[kylerguyler]

everythinhg about this is 10/10. idea, project, editing, dog, music, all of it. literally grinned ear to ear many times throughout this. love your shit man, keep it up
