Re: Scanning underwater

Sounds like a good plan. K.I.S! :D
I bet a potted IP camera would give great results.
I've stuck a go-pro on the end of a long rod before now, and the results are amazing, even in cloudy water because you can get up close to your subject.

Re: Scanning underwater

HC-SR04 work well in air and are dirt cheap! I use these a lot for range-finding up to about 4M with resolution of a few mm. Fitted to a servo they make a very cool sweeping sonar for robotics (reducing the need for several devices). This does NOT give a view of the swept area, the device must stop,...

Re: New comer

WOW! I assume that they are electric subs? What thickness hull do you have for 3000', is it double skinned? Does it have a separate capsule for the crew or is it a one-piece craft? Sorry about all the questions! How do you manage buoyancy? For my uROV, to conserve thruster power, I was thinking that...

Re: Using a Load Cell as a Depth Sensor

Did you get your depth gauge working? This looks like an interesting place to start for a uROV project, so I've been looking at the devices suggested above. G1/4 Pressure Transducer Sensor 0-10MPa for Oil Fuel Diesel Gas Water Air 10Mpk equates to about 1000M of depth, and the output voltage ranges ...

Hello there!

A quick hello and a little about me. I have a 'hankering' to build a uROV or possibly a surface 'mapper' (gps/depth). The problems fascinate me. I live in the UK near the Severn estuary, so with raging tides and seawater like soup, (you can't see your feet at ankle depth), I'll probably look toward ...

Re: Depth Gage for the electronically challenged

You could use some string if you really don't want to go down the electronic path :lol: You might want to look at Arduino, WeMos etc. They are very cheap and powerful. Personally I'd recommend Assembler, but the Arduino IDE is very quick to pick up - lots of samples and tutorials. Well worth the inv...

Re: Starting 3D CAD? Give Autodesk 123D Design a try!

One of the nice things about 360 is the ease of sharing work between a group. Collaboration is really easy. It also easy to import hardware drawings from mcMaster-Carr, nuts, bolts, pipes, etc. nearly everything in the catalogue has a CAD file. This frees you up from the mundane stuff. For a free ap...
