A quick noobish question: I want to make up my own DC power cables (male to male 2.1mm), but have no idea where to buy the cable itself, or even what I would call it to search for it. I'm in the UK (and looking for it to be cheap!)
It's nothing fancy, just the usual twin black wires, with one wire having some kind of polarity marking on it. Given that it is part of pretty much every AC to low voltage DC power supply ever made I thought it would be easy to find, but I've failed miserably.
Can anyone help?
