Homebuilt ROVs Forum

Thank you for the suggestions, and the wiring diagram. The concept of using single pole relays is an intriguing one, however I shall need to look at that wiring diagram more closely to see if it is a suitable one, not being able to read them fluently it shall take me a while but it might be somethin...

I've submitted a support query to RapidOnline, since they have a group of technicians who answer questions relating to products, to see if it is possible to switch a 24V DC relay with 12V. http://www.rapidonline.com/Electronic-Components/DPDT-10a-Power-Relay-24v-Dc-60-1673 I'm looking at definitions...

RapidOnline offer some very good shipping rates, orders under 1kg but over £25 are free and other 1kg is £9.00, meaning you could order 10kg worth of stuff and it all will only cost £9.00 shipping. I have found another PVC manufacturer online which is also cheaper, so I've managed to bring my cost d...

Thanks for the continued help scubersteve,

I shall look and see if I can find some, although nightmares of the last ROVs are coming into mind at the moment. This, finding PVC pipe online (no store shall stock anything suitable on the island I live on), and the budget where the main issues.

Even if it says:

Min. switching load: 1V DC, 10mA

I'm struggling to find some otherwise, at a reasonable price including shipping that is.

It's looking very good, an impressive setup to say the least!

Don't worry about the mess, all great inventions and ideas come from a cluttered corner of room.

Ok, Here is the complete parts list, including cost. It is a bit above my original budget (approx £50 ($77)) however with the late arrival of some birthday cards I think it shall be OK. I still am going to look for some areas which I can price cut, however as I say, it is feasible. Some of the items...

Thanks for the reply, So does this mean if I am going to draw about 10 Amps per motor I need a 12 Amp relay? Can this relay be rated for a higher voltage, for example: http://www.rapidonline.com/Electronic-Components/DPDT-10a-Power-Relay-110v-Ac-60-1675 which are 10 Amp 24V DC? And for the switches,...

The project is looking good so far!

What is that monitor you're using? Is it from a car reversing camera set?

Whilst attempting to find some cheap mineral oil which I could use to fill my electronic and camera enclosures, I happened to come accross this bottle of Johnson's Baby Oil on Amazon.
