Thanks Neil. I can solder and crimp!

Is there any kind of numpties wiring diagram for making one of these?
Thinking I may also need 12V in my control box for the motion controller. Would the PSU your talking about making be able to supply that as well. Or would I need a separate supply for that?

I have seen circuit breakers in other peoples boxes. Is the breaker in my consumer unit not sufficient?
I would also be running my kit on a normal 13Amp house ring. Does that still work?

Sorry to be a complete newb.
Thanks Neil
