I'm enrolled in the course and building the drone. It is an incredibly good course, and not only does it cover everything you need to know about building this drone in great detail, it also goes over thoroughly the other techniques used in the industry and what the other drones are doing. Truly if you want to build any kind of home-built ROV at all, you should take this course

@justingort1 Жыл бұрын

@@conorstewart2214 yes and no. After a certain point you have to worry about the voltage used. This needs to increase with length. Let's say every meter the voltage drops 1V as an example. Using a 5V signal can already give problems at 3m as the voltage would reach the logic voltage threshold. This can lead to false signals or even no signals. If they would go past the voltage of the ethernet adapter they would need a Amp in-between the laptop and the cord and the cord and the sub. This sub side is needed to prevent voltages high then the support voltage to enter the pi in this case

Keep up the great work guys! As a professional ROV Pilot/Tech, its great to see this type of stuff getting people interested in subsea exploration. The ability to build a cheap ROV that can hit depths beyond 30 meters will open up so many opportunities for KZfaq creators who could never afford a seabotix or blueROV before. I’ll definitely be building one of these as soon as I get home again.

Amazing project. A tip from an experienced professional in this subject: epoxy resin seems amazing at waterproofing, but as the time passes it starts absorbing water and eventually will "sweat" water inside. We use the same glue used in fish aquarium (we call it silicone in my language, not sure in English) to this purpose, applying vacuum and releasing it before curing will make the glue fill gaps with excellence, and it'll last more than epoxy. We use it in the electrical connectors of our robots.

Beautiful design. For the end cap you could have soldered the wires to a connector/connectors and then used the epoxy to seal the end cap, solder joins and hold the connector. One less set of solder joins to deal with. By adding guides for the connector to the end cap 3d print you could have "standardized" the connector positions and would so always know where the connections would be. Hope the idea could be helpful to you or anyone trying the project out.

@hamesparde9888 Жыл бұрын

For the wires I think you should have made thin 3d printed wires spacers and then used two or three of them along with some solid core wires with no insulation and then soldered the wires for the outside so that the insulation went a little into the epoxy. For the inside you could have a connector partly in the epoxy. This way there would be more epoxy touching the wires direct and the spacers would make sure the wires don't touch. I think just one solder point isn't the best. But if it works it works. Also I wasn't really surprised that water got in. In fact I'm surprised it didn't happen with less depth. Anyway it's a very very nice looking build. Good work!

I love the design. I'm working on my own, but I'm using ballast for levelling/lifting/diving. It's also going to be about 1/4 the size. But I would never have thought that water could leak in THROUGH the wires! So this video has been a great help!

@hyperFixationStudios Жыл бұрын

This is really cool! It would be interesting to see its ability to handle open ocean conditions! An underwater drone has been on my todo list for a while, my only question is if it's already tethered why not tether power in to the drone? It'd remove the need for batteries onboard.

@CPSdrone Жыл бұрын

Thanks a lot! So the longer tether we use is 100 meters (330 feet) long. The wires in there are 26awg. So the total resistance of each wire is at least 10 ohms (20 ohms for the wire going into the drone and back). And that's too much for our 6A power requirement if using 60 volts. Also, 60V in the water can be dangerous to wet skin. Batteries are just cheap and effective. We will maybe try doing that with a bigger ROV we plan building for wreck inspections, so we'll see

@Simon_Rafferty Жыл бұрын

Although I've not built a submarine, I have made a few waterproof electronics enclosures using a similar method. However, for the through connections, I've used long DIP headers which poke through the epoxy with enough sticking out both sides that a regular DuPont style connector can push on to the inside & outside. This gives a tidy and fully waterproof connector. Each pin will handle about 5A, so some of them need to be doubled up for higher currents. It's simple - but it really works.

@ddegn Жыл бұрын

Were you able to test under deep water? I'd worry the metal pins and the epoxy would expand and contract the same amounts and water would seep past the pins when the pressure is really high.

@Simon_Rafferty Жыл бұрын

@@ddegn That is a consideration. We used EP42HT-3AO Epoxy which has a coefficient of thermal expansion similar to common metals such as steel or brass (the pins were Brass), with good bonding characteristics. If you just use any old glue you happen to have - yes, you are likely to have issues. The trsting was to IP69K (Automotive) - so wide temperature ranges. I don't remember the equivalent depth it was pressure tested to. This was only for a test rig. The final product used USCAR IP69K rated connectors.

And I would add one of the bright beacon led lights, that are used for model aircraft and drones, to the top of the sub for that case so you can see where it floats. And as an idea. I would change the ethernet cable to a fiber optic data cable.

@chomp7927 Жыл бұрын

fiber would require media converters on both ends and jack the price up a lot, plus if/when you kink it, it's done, and after pulling cable for 15+ years in the army, ethernet is stronger pull wise then any cheap fiber you would get, and by the time you get stronger fiber you might as well just buy a real drone with the costs lol Hell you could probably work some sort of charging mechanic and a POE injector in for cheaper then fiber would be Everything else sounds fine though
