As you can see, this is long:

But we got an email from a (unrelated) user saying it's good, so I've put it in the SCP (https://news.ycombinator.com/item?id=26998308).

ROV = remotely operated vehicle btw

TFA is nothing short of amazing and absolutely deserves attention.

The author (and his brother) built (from scratch!) a side-scan sonar remote controlled boat and an ROV (a remote controlled submersible) with a camera and a light, and with this they found TWO missing persons' cars under water. Real products of these sorts would have cost enormous amounts of money, but they built their own for the cost of parts and labor (sure, lots of labor). They did this on a lark.

You can buy similar off the shelf, the way these diy projects go it may have been cheaper in the long run, but more power to him. It can be hard to drop 5 grand on a kitted out submarine when you think you might be able to do it for 2k in parts in your own labor, but in my experience that 2k in parts starts to creep up as you accidentally destroy things, determine that the things you bought and can't return won't quite work, etc.

There is a guy that has been using one of the off the shelf ones in the lakes around seattle (https://www.youtube.com/@rctestflight/videos), he's also built a bunch of other rc stuff including a few autonomous boats that he takes into the lakes as well as the sound.

Yeah, this was a good read and definitely the kind of material I come to HN to read.

Thanks for giving it a second chance. I read all of it, and it was very interesting indeed

In the video in part8, at 0:30s there's something that could be a hand. I hope it wasn't a hand. There's no comment in the text of what it might be.

Would be great to be able to read all of these as a single article! (I'm intrigued, but I'm not saving 13 blog posts to my read-it-later app. Even stitched together, it wouldn't be the longest in my list by a long shot.)

I agree and sometimes email authors to ask if they would compile (or should I say link?) a multipart article into a single piece before we put it into the second-chance pool. But even I was afraid of how long this one would turn out to be.

For articles like these, I use shiori; it's a webclipper that saves html to an sqlite database. Then you can concatenate them with a single sql statement. If the final product is particularly long, then I use calibre convert the result to an epub to read on my phone and/or ereader.

It's just one article, with 13 pages. There are page-turn buttons, like in a book. You can do it. Bookmark the first page.
