Coils, what's that?
Dino - firstly, be practical. Please do not expect to perform magic if you do not have some necessary test equipment. Over and above a basic multimeter, it is a very good idea (that's putting it mildly) to have an inductance tester. An LCR meter is very convenient, and a cheap frequency counter is also a good idea.
I purchased a combination meter from an Ebay store last week, (a long overdue investment). It's a Mastech MS8222, that I got for a reasonable price. My new meter is NOT fancy, but it measures "L-C-R", and even frequency to 20kHz. It has reasonable accuracy and resolution specifications. It seems to be adequate.
If you don't already have LCR and frequency measurements covered, then you should look into it. I know that I am "lucky" by being in Ebay's backyard, but I think that you can probably find international sales.
Find a free download called CoilCalc. It is pretty cool. There are other coil calculators. Qiaozhi posted one I think he created. There are many free coil calculators that can be found on the internet. You just have to look! (Use Google.) Also, find some wire specification charts so that you can convert wire guage to diameter, and to help calculate ohms per unit length of wire. There are many free coil calculators, and many MANY wire guage conversion /specification charts. Nobody can do the work for you. You must remember that "coil calculators" are only as good as the data you feed them. Also, remember that the calculation results will probably be based on assumptions that are, more than likely, counter to your intended goemetry! X, Y, and Z (length, width, and height) dimensions must be FUDGED. For instance: is your coil shaped more like a donut or a tube? Or is it planar? And, boy howdy they are different. THINK about how the data you are entering will be interpreted by the computer. You can also use a pencil and paper and research the coil formulas!! (Just kidding, don't do that.) No, I'm not kidding. Oh boy, my brain is getting soggy so I'll wrap this up.
Oh, yes, don't neglect to read over the previous thirty or so pages of this thread - and other related threads - for some good ideas.
Good luck!
