Homebuilt ROVs Forum

FIRST OF ALL, HAPPY CAPSLOCK DAY AND HAPPY TAU DAY. secondly, I was on #arduino (irc.freenode.net) and they helped me with this issue. Basically the arduino only communicates with a computer via serial (Note that USB != serial). On the arduino there is a USB to TTL serial chip which routes the commu...

how would that help?

So you are planning to have the arduino control the thruster's using motor controllers, as opposed to relays, if I am looking at this correctly. Do you have to worry about loss of signal with the arduino over longer distances, or is this not an issue? What camera will you be using? Looks very nice ...

you can use adapters, that can transmit the usb data over a cat 5 ethernet cable, up to 150 feet, I've using one at the moment that's 30m, 90 feet. Adapters are something like $15 off ebay Regards Martin Not finding what your finding because all I'm finding is ethernet to USB (aka what you'd use to...

lets all gather on #ROV on freenpde =D

the usb would just be for data, no power. power would be supplied by a SLA battery or a 12AWG wire. I want to do somehting with higher res than RCA, but i might have to settle if there no other feasible option.

I meant away from the forum. like on freenode or something.

Originally my plan was to run 2 USB connections over a 50' cat5e Ethernet cable (1 for control, 1 for webcam). Problem is I tryed it and it doesn't work. So now I need ideas on how to get webcam and control data to and from the ROV. I was thinking of using Ethernet and a switch in the ROV, but for t...
