    Hi again.

    I, have tested both programs, the exe one in my sister computer(she use windows, and i only Linux ), and the web based one (with iceweasel(it's a fork of firefox for Debian) and it's run ok because it's run on server and we only need a web browser who support htm )

    I have started with a small app for calculating, this is the first version of it, it's only a command line, and it could be compiled in any machine and in any operating system (you only need a C compiler to do it).
    This version only work for a square ends coils, for the measurements of the coil you need to count the insulation tape for protect the magnets (if you use any), i have include only two types of wire AWG #42 and AWG # 43 (i get the diameter and the ohm/km from this web site http://europa.spaceports.com/~fishba...e/wiredata.htm and plus to the wire diameter the insulation of it)
    Who it's work:
    After you put the core, the impedance wanted, and select the wire, the program calculate the length of one turn and multiplicate it with the number of turns per layer, if the length per layer is less than the wire length need for the wanted impedance repeat it, in each repeat it increase the core's measurements and reduce the wire length (new wire length = wire length - length of the layer), and increase the number of turn by the turns per layer.
    When the length of the layer is great than the wire length, it divides the wire length by the turn length to get the turns to left and increase the number of turns by it to get the total of turns we need.

    I think this app have a lot of bugs, but i think it's a good starting point, to get a nice winding calculator, in the next version i will add more wire types and write a gui for it in Qt3 to allow to run in win, macosx and any *nix who have the Qt3 libraries.

    Use it with any warranty and at your own risk.

    If you have any commentary, let me know

    Thanks and see you later.

    PD.
    I put two images and the program with the source.
    Image of the measurements of a coil


    The "program" in action


    The two jpg of the measurement and the program, and the source code and the program compiled under linux x86 http://webs.ono.com/meropx/winder/winder.tar.gz you could open with "tar -xzvf winder.tar.gz" or with winrar for example.
    Yes i know, i need to improve a lot my C and English skills
