    Hi all, as i live on a remote island, i was thinking of making my own air core inductors.

    Any 1 here has ever done that ?

    Or mabe a new video to make for @123toid ?

    I probably won’t be able to do a video on it, but there’s some good websites like this that help with it. https://www.diyaudioandvideo.com/Calculator/AirCoreInductorDesigner/

    ^^Sites like that are good for getting you going quickly, but if you want a deeper understanding, go to a site like Elliot Sound Products (ESP) and look up inductor. Gives you the theory behind them and all the hand calcs (and Excel sheets) so it really sticks. I had his page up but my phone shut all my groups and wouldn’t restore them before the undo went away. (Poopy!) It’s easy enough to find.

    Also, there are some guitar YT channels that wind pickups that help with technique. Wills Easy Guitar, or whatever he’s changed to lately has some good tips.

    @tvor-ceasar I found some really helpful websites, including http://www.troelsgravesen.dk/ and https://daycounter.com/Articles/How-To-Measure-Inductance.phtml

     

    But I cant even source some inductance wire on this damn island, “not enough demands” is the reply i get. 

    Anyway i might need to order from mainland or even the US or china (closer) or india (even more closer)

    @jay974 Look up Magnet wire or Enameled wire. Most important spec you’ll need is the wire gauge so you can get the current capacity and cross-section for calculation. Maybe you can find some old motors or transformers to unwind.

    I started looking for old microwave oven transformers, I used to have fun with those for making jacob’s ladders or melting stuff…….and now I really need some they are impossible to find…..
