Joule Thief

[Dave45]

I have built both pnp and npn, actually Iv built many combinations in the last few days.
The pnp runs the led brighter, Iv used many different cores as well, toroid, split core from a flyback, small transformers.
No self runner yet, maybe tomorrow.

Only charges one side of the cap!

I thought I'd heard pretty much every claim about an electronic circuit imaginable, but that is the first time I've ever heard anyone claim that.

I invite Dave to perform a demonstration showing that only one side of a capacitor is charged, by any means. Certainly one can tie one side of a capacitor to Earth ground, and then charge up the capacitor. WRT ground, the side connected to the Earth will of course read zero voltage. Does this mean it isn't charged? Or does it merely mean you are using the wrong reference, because of your flawed understanding of charge and electrical current?

Dave is civil and Dave is doing experiments to test his ideas.  I think that deserves civility back.

I think that ridiculous claims made without support deserve whatever response they might engender. But perhaps you can tell me how asking for a demonstration of a claim is somehow "uncivil". Dave has shown his great propensity to misinterpret his "experiments" in the light of his own preconceived notions, which do not jibe with conventional understanding, and which are leading him astray. This has been pointed out to him, civilly and uncivilly, several times before and anyone can look back in the thread to see how he responds.
An experiment is done to test an hypothesis. A demonstration is done to illustrate a point. We are seeing demonstrations, not experiments, from Dave, and he is interpreting them according to his notions, not according to what the data reveal.

I make no claims as fact,, just my view.
The battery charges the cap but when the oscillator kicks in the bemf from the collapsing magnetic field charges the pos side of the cap and also depletes the neg side.
I am testing and will post results.
I dont really care if Im right or wrong, I want to find the answer.
