for RC underwater stuff i think having a rescue line on it at all times seems like a good idea.

its a shame this is a limited project, I'd have liked to see this project develop a lot more, It's an awesome concept.

i think part of the issues have to do with inherent features of the lake bottom - as a low-energy environment with almost no current, the sediment will consist almost entirely of silt, clay, and fine-grained biologically-generated material. this has the effect of: 1. making it harder to drive as you'll tend to stir it up and sink in, and 2. meaning that any sediment stirred up will take a long time to settle out, so driving will inevitably make it very cloudy.

btw that smell of lake sediment is often due to methane bacteria :)

This was a great project! I have two suggestions.

1. Use a compass to get an idea of the direction you are pointing.
2. Strap a "safety balloon" with a co2 cartridge to it and inflate the balloon if you get stuck. If you do it right, it will stay upright and lift the top of the tracks above the water so that you can use the tracks to "paddle" back to shore.

This is a great concept ! Once again your crazy contraption is amazing ! My suggestion for “version two” would be to have a larger surface barge and a small additional spring loaded cable with an electric winch to lift the underwater rover in case it gets stuck or fouled in the weeds.

Hey Daniel ! For the video signals you definitly should use coaxial cables. It will have a "shield" functionality and will prevent the video from being jammed by the other signals such as power or ESCs. As it's low speed signal you don't care about impedance and can use both 50 or 75ohm cable. There are some really thin ones available. All you have to do is solder the signal on the inner line and GND on the shield on both sides (rover and barge). Hope it helps !

Also you can have a bobber on a shorter tether as deapth gage, so it gets pulled under before the main tether, then you know when to turn back

I really want to try this with one of those spider robots underwater

[andreparmen]

As far as day to day environments go there really isn't a more destructive one then the marine one. its ability to silently destroy has to be admired in the endless ways it attacks systems haha.

Keep up the work man, you make me wish I never stopped building and experimenting with theses things.

01:22, you can make PLA waterproof if you put it in aceton vapor, the walls melt down and create a glossy plastic finish which seals all the layers together like a molded plastic.

[unusualfabrication]

absolutely LOVE underwater stuff! would love to see more things like underwater crawlers and ROV's!

[FullCircleTravis]

If you need to waterproof, there is a product made by Lawson called LPA III. It's basically lanolin and parafin wax in a acetone solvent. When you spray it on electrical boards it waterproofs them. I've tested this for underwater operation. It's better than potting because it allows for heat dissipation and can be removed with a solvent safe for electrical boards. You could seal 3d prints with it as well.

This is INSANE, daniel! Wish you and your community here a merry XMAS! 🎄🎄🎄🎄🎄

sonar works better then radio waves when trying to transmit data underwater, if you ever want to be tether-less i suggest looking into it

In the future for small amounts of moisture, you can buy silica gel cat litter for extremely cheap compared to the packets made for drying.
Drop a few granules inside the “dry zone” and you’ll be good. I keep 3D filament in a big Tupperware tub with the silica litter sprinkled on the bottom because I live in FL and it’s swampy as hell, but the filament stays crazy dry! The stuff works incredibly well for how much you use. Literally a few granules would keep a housing like your camera dry.

It’s useful stuff, you can use it for a ton of things you probably wouldn’t think about until you have it.

[helicopter]

Maybe add a little winch for the cable on the sub? That way it could use the top boat to pull itself up and let itself down at a suitable place?

[isaacm]

0:43 So it's just you sir! Any video that you made was excellent and catch the attention easily. I bet that even a video about that RC in the snow would make any person like.

Have a great day, don't overwork yourself, sir!

[Project-Air]

So much better than my tethered submarine 🤣

[shayes.x]

Awesome prototype! It would be really neat if the barge was RC as well, with a winch that could raise and lower the rover to help recover it or place it in specific areas

4:28 the bubbles reforming after every turn was pretty cool XD
