The main difficulty with sending power down a tether is to do with the desire for a long, thin tether. You want a tether long enough to be useful, so usually many tens of meters, plus you want it thin enough to be flexible. First, let's look at length. The longer the tether, the bigger the voltage ...

Sorry if this sounds like a newb question, but how are you using the RS485 module in this setup? Does it translate control data?

Have you received the enclosure from Blue Robotics? How do you think the value of a premade enclosure compares to a homemade one?

I’m in the brainstorming/early planning stage of designing a freshwater ROV. I’ve noticed several people power their system with a car or golf cart battery. I like this idea because I’d like my ROV to stay underwater for long periods, and from what I’ve read on-board batteries tend to deplete faster...

Oops, I meant to post this in the Introduction threads. Sorry about that. If any admins come by could you relocate this? Thanks!

Only thing is, with no significant experience on the water or in the industry, it’s a big leap to go from l...
