Homebuilt ROVs Forum

Hi Dave, Using bike inner tubes to get the neutral buoyancy is a good idea IF you can adjust the amount of air you have inside during your dive. The air will compress as you get deeper. For example, if you start with 1 liter air ind the tube at surface then the volume will be compressed to 1/2 liter...

Really nice! What camera did you use, did you get some good under water footage?

I had the same problem. Now I'm rebuilding my rov with two vertical thrusters. One right and one left propeller.

Thanks for your info Steve,

I´ll looking forward to see how good it performs.

It was really awesome, they had both ROVs and a Submersible. Got to go down to 1000 m depth in the sub, it was of course a great experience. The engine...

I did a harbor dive and on the small monitor I use it looked ok. But on a bigger screen you can see that it is out of focus. GoPro has fixed focus that works well behind a flat port. I have tried to correct the focus with different lenses. +10 diopter and more gives focus in a very short distance. I...
