Joule Thief 101

Good on the wit, but your comment is still not true.

You are of course entitled to your opinions, just as I am entitled to ignore, disagree or agree with them.

Exactly Webby.

Soft iron may have a high value of stiffness,but a very low value in elasticity.

As i stated in one of my replies to MH-long ago,the makeup of the glass(crystal)will determine the value of elasticity,and it is that value of elasticity that will determine the resonant frequency of the wine glass. Even with keeping to the same size and shape of wine glass,we can raise or lower the resonant frequency of that wine glass by changing the value of elasticity in the glass-change the type of glass used.

Please go ahead and link to your quote about elasticity because I don't remember anything like that.  Feel free to link to your best answer also if you are claiming that you answered both questions successfully.

Well I have made thousands of postings filled with good solid information and in the earlier days I helped people understand their circuits all the time.

I Honestly feel your Big reveal will in no way change any builders resonance hunting technique,
not one Iota .

the builders mentioned many very simple methods they use for this purpose ,and honestly they make perfect sense .

from my perspective having had the privilege of several very good Mentors in this EE field and having witnessed many very good resonant hunting techniques by very experienced persons on threads at this forum and elsewhere.
,I feel your big reveal is a big let down for the builders .
and I strongly suspect your are fetching for any true reason for this fiasco  other than some Bragging right and a chance to belittle your foe and others here at the playground !

Honestly I can completely understand your ignorance on ICE science.. its quite understandable.
what I cannot understand is your willingness to open your mouth as an authority when you are completely clueless.
and this is very troubling.. considering where we are ..and the depth of what is touched upon here.

Regarding the question about which wave form was the correct one, I'll go out on a limb and say neither one, because I'm pretty sure you inverted CH2 (the current channel), and I did not see mention of this. Therefore the wave forms could not appear as they do with the probe orientation as depicted.

If CH2 was not inverted, the primary current would be lagging the secondary voltage.

How do you get an EMF across  the secondary before current flow through the primary?
