Joule Thief

Hi everybody,
I posted this next door. I thought I would share it here too.:

I was looking around for help with inductors today and found 2 calculation sites.

I like the first one better, but they are both probably great.

http://www.66pacific.com/calculators/coil_calc.aspx
and

http://www.daycounter.com/Calculators/

The progression looks good on the 66pacific site.
If you start with your coil you get the henries then you plunk that result into the next one.

have a look,

jeanna

edit.
That is a great analogy, Bill.
I really like that.
It makes the point very nicely that you can do something entirely unheard of using the elements you have had at your disposal all along!

Thank you.  I remember reading in one of my Tesla books that once, Mark Twain (Samuel Clemons) went to Tesla's lab, which he did often, and it was very late at night.  Twain described what he saw in great detail.  He said Tesla went into the dark lab and switched on a small device and suddenly, the entire lab was lit up as bright as day.  He described evacuated tubes positioned all over the lab that were lit up very brightly giving the illusion of daylight.  To me, this sounds a lot like floro tubes being driven by high voltage and yes, high freq.  He went on to say that no wires were attached to these tubes and Tesla even picked up a tube, and walked about the lab with it and it remained very bright no matter where he walked.

This is why I believe that our higher and higher volts matter on the JT experiments.  I really believe we will be able to do even more amazing things at higher volts and higher freqs.

I also wanted to add that Free said his tube was about 30% of full brightness, I too would (and may have) described my one and two 48" tubes lit from the Fuji as about 30%.  I think this is a good estimate made from the hip.  Maybe a little more, maybe a little less but this is close in my opinion.
