Wow - very high quality video. I hope my ROV turns out as well as yours has.

All that scrap metal down there must be worth a few £ now

Not sure about the rest of your wiring but it looks like the relay is connected to one of the 10 Open collector outputs - this means that the Velleman K8023 will sink current down one of these 10 outputs not supply it. So the relay must be connected to a +ve voltage and the other side of the relay c...

In my ROV which is still in development I have used a similar converter, seems to work OK and produces reasonable video. An advantage is very low cost and the software provided is simple but works. The only downside was the overall picture size, it was limited by the software to a smaller window tha...

Excellent Video, your ROV is very agile but also very stable which makes the video look good.
Surprising lack of fauna in the water despite the water being very clear. What depth did you go down to? Are there any fish there?

The Makibox was one of the printers I considered late last year when they were 'fire selling' them. But eventually bought a DaVinci 3d printer. This has a whole new set of problems! I changed the heated bed glass which on the original was just a window pane cut to size to a borosilicate piece and us...

@perso - I hope that the linear bearings resolve the issues with the Makibox, it is very frustrating when things don't work straight out of the box! Regarding Glueing ABS - some makers with 3D printers use an acetone slurry, which I think is acetone mixed with bits of ABS. ABS dissolves in acetone s...

That's a really nice manipulator - thanks or sharing it. I have been playing with Onshape, the free version. That also looks very good! At this time I use OpenScad for 3D Printing and Freecad for modelling. Onshape looks like it may do all those things but will need some practice to become proficien...

Getting a 3D printer has been great to further my ROV development! So I hope your arrives soon, it is a tremendous boost to get things prototyped quickly and see how the parts fit. The parts can be made very cheaply - if one forgets the cost of the printer

Thanks Steve for making this available - there is a lot of very useful information in there!

Hi Diving flashlights are a good idea. They are ready made, so need no special tools - lathes etc. and may also be lower cost compared to making one's own. I am making my own lights as I could not figure out how to switch the flash lights on and off and also dim them when the ROV is diving. Some div...
