    I have an AC to 12V DC adapter that has the ferrite cylinder on the end and a barrel plug. Its the kind of wire that has as positive core that is insulated and then the negative wires are around the outside of the positive core's insulation and then the whole thing is insulated, kind of like this:


    but the negative goes all the way around. Anyway, is there any simple way to turn that into having the positive and negative as 2 separate wires? I know there's an adapter you can purchase but I already cut the barrel plug off. Stupidly.

    Any help/advice would be VERY much appreciated. Thank you!

    you just cut back the outer insulation and unwrap the braid then twist it together.

    Then you strip a little of the inner conductor.

    Bingo -- 2 things to connect.

    You can slip some insulation over the braid if you desire.
