I thought there must be something out there already but it's a difficult thing to 'google' for without a name or use-case. Never towed (or had the desire to tow) a caravan so wouldn't have thought of searching for caravany things.

I bought a programmable 12v relay to power a dash cam and USB sockets while protect the battery. Works without problem.

I'm glad I never managed to find the time to design a circuit now.

That's one of the great things about China ... If you can imagine it, you can guarantee someone in China is already making it!

That's right. China produces huge range of hobby electronics. Whatever you need is there. Hard part is thinking of what it's called and listed under!

My problem is like the original Laser one.
I start meandering through the Chinese suppliers on fleebay and start to find something to do with what they are offering.
I have a hobby drawer full of started but never finally finished projects that hopefully I'll find time to complete.
Though sometimes, only rarely mind, a new "I want it now" job comes up from SWMBO and she thinks I'm clever 'cos I click my fingers and say something like "I have the ideal thingy for that". She is very good, never pokes around in that magic drawer.
Then again, I guess the total spend in that hidy hole is only about £20.I can't believe the stupidly low prices they charge and usually post free. I've only ever had one non delivery item that cost me £0.76 and the supplier wanted to send another one, but they were so nice I said don't bother I'll find something else to buy from you. Under a pound is always worth a punt. Their profit margins must be pretty low.
