This is Part 3 of my ongoing efforts to create an underwater remotely operated vehicle.
If you haven’t already, check out Underwater ROV Project (Part 1) and Underwater ROV Project (Part 2).

Welcome to part 3 of the Underwater ROV Project. The saga continues! Like many journeys there are ups and downs, and things usually take longer than expected — but that’s ok.

So where are we, and how far have we come? Let’s take a look at where we left off from Part 2:

After Part 2, we had the chassis looking more complete (thrusters attached, a hole drilled for the CAT5 tether), and the electronics stack in a functional state where we could connect to the onboard computer (Raspberry Pi Zero) and run fully off of onboard power. It’s starting to look more like a sub!
