Re: Small coil project

I see dozens of posts of this type over time. Some "what ifs"
ask about safety, others ask "what if I do such and such". The safety
what-ifs are a good thing to ask about if you have little knowledge
and/or work experience with electricity, and you can bet your bottom
dollar all your questions have been asked and answered previously
with details contained in excellent FAQs in the list archives.
But the second type of what-if can be usefully dealt with by
experiment. Trying things is exactly how you learn, especially when
things don't go as planned or hoped. A recipe from someone else is
great if all you want to do is build a coil that works OK (not a
particularly satisfying approach for me I must admit) but if you wish
to learn, try. Post the results if you wish. Let us all learn from
your experience. If results are disappointing, make an effort to
figure out why. If they are top notch, let us know about it and make
a name for yourself.
