I loved the project!! I also like how “messy” the room is, reminded me of my room (1) when I was working from home years ago.
I haven’t read the whole thing but I will, however, I did go through the technical details, some notes:
> This model didn’t have a long enough range on the analog sticks
I see you are using Radiomaster tx16s, pro tip: You can use ELRS 2W model on BOTH transmitter and the receiver, don’t use the typical receiver unit, use another transmitter and flash it as a receiver, and you would have 2W on both sides, preferably 900mhz not 2.4ghz, and you would’ve hundreds of kilometers of range and strong obstacles penetration.
For the camera and the tether, technically you can get rid of the tether and use wireless comms, but probably what you did is the best for bucks solution.
Overall, looks great!

- jonah 2y agoI took the comment[1] on the analog sticks to be referring to the game controller pictured directly above: https://suanto.com/assets/2024/03/the-ROV-controller.jpg https://suanto.com/assets/2024/03/the-ROV-controller.jpg I'm guessing that the range of resistance values over the full swept range of the sticks was small, and so getting precise enough values/smooth enough change out of it wasn't possible. (Assuming these things basically have X and Y potentiometers for each stick.) [1] https://suanto.com/2024/06/06/the-time-I-built-an-ROV-06/ https://suanto.com/2024/06/06/the-time-I-built-an-ROV-06/
- bigiain 2y ago> I'm guessing that the range of resistance values over the full swept range of the sticks was small My assumption was they meant the distance of movement on those small joysticks was too small, so the precision problem wasn't measuring the resistance, but in accurately moving the sticks to the right place to get the desired control input when they only have tiny amounts of travel.
