Homebuilt ROVs Forum

I ended up tweaking the grub screws on the adapter more yesterday and it seems to be ok now. I think because the shaft has a small section cut flat, during operation the adaptermust have moved/twisted a bit so that it was at an angle. It took a lot of fiddling but the shaft is straight again now. Go...

I'm using some cheap Cat6 and noticed that the outer jacket is pretty flimsy and thin looking. Fairly sure that at some point I'll end up needing to replace it due to floods etc. When I do I think I'll make a poin t of trying to find something that has a thicker outer jacket, if possible.

I really am a beginner in electronics, despite somehow managing to get a working ROV built! The guide I followed suggested using a Car jump-starter battery, that runs on 12v dc, as it would be "safe" to use in a pool situation. Being the complete beginner that I am, I'm wondering what this...

Thanks, the wifi is just for being able to see what the rov camera sees, as well as camera control. By this I mean start/stop recording functions, changing from video to still images, telling the camera to take a photo in still photo mode etc. Actual control of the rov is via the 3 motor switches. C...

Annoyingly, GoPro has just announced the 3+ model, which has improved WiFi capabiltities. Decided to try and swap my 3 edition for the 3+, to see if it's improved the signal at all!

Yeah, the gopro has a mic built in. Not sure how useful the sound is underwater, at the least I guess I could hear the vertical thruster slowly getting more wobble over the course of the dive. You don't get sound on the live preview app though...

Second trip out. The vertical motor seems to have developed some bad vibrations during the course of the dive:

So my ROV has been out for 2 test dives so far. First trip was pretty much ok. Yesterday however, over the course of the hour it was out, the vertical thruster (johnson 750gph pump) developed a lot of vibration. Looking at the prop,shaft etc, when I turn it slowly it's angled slightly now. Only a fe...

Hello all from Bournemouth, Dorset, UK Where to start...(sorry, it's a long introduction...I somehow managed to build an ROV before discovering this place!) I've had an interest in photography and experimenting with gadgetry from a very young age. I've spent the last 10 (almost 10 anyway) years at B...
