    Post Inductors...

    Gudday,
    Just wondering if anyone knows how to wind the Inductors (chokes?) used in DC-DC PSU's like Sproggy's?? I could buy them, but I am intending to doubble up on a lot of the sections (ie to get twice the power) so it could get a bit expensive. Also, it is something that I can make so now I just want to know how to! Also, if I connect two systems (ie 2 * 5v reg) together am I going to have them competing with one another to supply the power (as suggested elsewhere for normal reg circuits)?
    Cheers in advance,
    Fabian

    Well, they aren't hard to wind. Just make sure to wind neatly and don't criss-cross windings...

    Here is how I wound an inductor for my -12v supply...i went to home depot and paid like a buck for a nylon bolt a nylon spacer, a nylon washer, and a nylon nut. I put all that together and then I had a perfect form to wind inductors on. I got on the internet and found a little Java program that would let you input the value you needed and the diameter and width...then it would tell you how many turns....I dont remember the URL just do a search.
