Homebuilt ROVs Forum

the Ardiuno usb port and the camera are both connected to a usb hub, which will go to a usb to RS232 converter, with the serial cable going to the surface.

How far does your rs232 go? I was trying to figure out a way to get my usb camera to surface too

I don't know anything about those OSD's, but you might be able to program it through Processing. I know for the full color LCD screens you can use Processing, very similar to Arduino, it MIGHT be the same for the OSD. But I am by no means knowledgeable about them

Thanks! That should work perfectly then.

Next, I really want to get it on screen (OSD) but despite having the hardware and apparently the software to do it..............

Will you be using a display like THIS (not necessarily touchscreen though) or display on your computer

Haha that's alright. But technically I could have the Arduino topside just connected to my computer with Serial.print() statements of what it's receiving from the Arduino on the ROV right?

Thanks a lot! THIS is what I mean by USB to cat5 converter. I still am not completely clear on this though. This looks like serial between two Arduinos, I need serial between my Arduino on the ROV and my computer. Can I use this setup with two Arduinos, one up top and one onboard, and connect the Ar...

So USB has a limit of 15 feet. I connected it to a cat5 converter(only USB 1.1 speed, didn't want to pay for the 2.0 speed) for my Arduino. The 1.1 has a max distance of 130 feet, and the 2.0 has a max distance of 330 feet. Has anyone discovered a way to get a larger distance with a different connec...

Okay so we have all thought about putting a GPS on an ROV, but there are many complications; really the only way for a GPS to work would be to tow the GPS directly above the ROV. Instead of relying on the GPS alone, would it be possible to use an IMU? Take an initial GPS reading when we are above th...

Wow impressive ROV!!
And thanks a lot these should be perfect for mine!

Are these connections underwater at the Rov umbilical / termination... Or above water, or somewhere else..? If its under water then what depth (Roughly feet, metres, miles...!) Are you going? Yes, these connections are underwater, basically a few inches to a foot down the line from the motors. The ...

I need some hefty connectors that can handle 12V at 15A, preferably threaded like the ones you can find on the back of a TV for cable. Has anyone used anything like this? Or are my power requirements way too high to use connectors?
