Yes that sounds right.

I am trying to use an air core where you used a big toroid.,......it is going to take  a little more wire.
This kind of coil seems  similar to  my LM coils in many ways.......If I remember right the LMs took about 8 wraps bifilar

anyway......time will tell if it is going to work.

I have been working on other things most of the day.,,,,,,, testing time is coming up soon

After a few hours of  playing around with  my air core coil I have decided  it is just not going to get me where I want  to go.
My best results were 15 ft  for base and 35 ft for emiter.
The power was low enough it is just not worth the effort .... I can get better results with many other means.

@ All,    I know this is a little off topic here but if I had a solar panel producing very low volts
            at high Amps 10+,  would  normal thin insulated wire work ?

I believe it would.  But, check other opinions here as well.

  Thanks,  just one more question... I will be getting a small digital panelmeter that measures 0-20v,
                 Now if I have a solar panel that puts out 3v at 8-20 Amps, would the meter be alright with
                 Amps like that ?

Hi folks, I posted this at other site also but no response. I picked up a few various ferrite toroids and I was wondering what jeanna or lidmotor or anyone else used to cover the toroids to protect the magnet wire. As shown in my pic, i used masking tape since it's fairly thin. Reason i ask is, because i unwound a small toroid yesterday and found that the insulation was scraped off at every point where the wire made the sharp turns on the toroid. I plan to use a 30 gauge secondary on the one shown with masking tape and try something with those larger bead type cores, going to try and light a fluorescent, though might not happen with such small cores. Anyway, thanks for all the experiments you've shared jeanna and lidmotor and all the others.

peace love light
