To quote MH from other thread.

The internal resistance value of the battery can be calculated on the fly MH--while the JT circuit is operating.
I wonder if you actually know how to do this?
My bet is-like always,you wait for some one else to give the answer,and then you say--oh yes,that is how it is done.
So not this time MH-this time you will have to work that out for your self.
We could just do the internal resistance test of the battery,while it is not in use in the circuit,but i wanted to be more accurate,and know what it was during use in the JT circuit.

And now you are back in full-blown stupid-ass trash talk mode. Look at you! Your brain is frying.

QuoteMy bet is-like always,you wait for some one else to give the answer,and then you say--oh yes,that is how it is done.

That is complete and total BS because your brain is frying and you will say any stupid negative thing about me, even if you have to shamelessly lie like a jackass.

Kiss my butt! O hapless one!

Then just state the two procedures and stop the ridiculous soap opera drama, for crying out loud.

I am going to give you a little reality check Brad.

I argued the first circuit was "more efficient" because it looked like it offered a longer run time by going down to a lower battery voltage and therefore could extract more energy from a dead battery. That is the basic Joule Thief premise.

Then you discussed the first circuit and the second circuit with respect to looses due to the internal impedance of the battery. Your argument was that since in the second circuit some of the time the battery was OFF and not supplying any current, that there would be less internal battery impedance losses. I proved to you that that notion is false if you assume the exactly the same power draw for both circuits. In fact, it turns out the first circuit will be more efficient using that efficiency parameter which is the opposite of what you thought.

I have no idea where you want to go with this. I proved that your assumption for the second circuit was wrong in terms of internal energy lost in the battery. If you can't understand what I said or how I arrived at that conclusion, then have a good brain fry, bring along some marshmallows.

Beyond that, the issue of most light per unit of input power is interesting. I already indicated in my first long posting that TK responded to that it's a quite complicated matter with many parameters to consider. I am not really that interested in getting into a long discussion about it.

Brad:

QuoteAnd so that is the difference between bench workers and pen pushers MH--the bench man will go searching as to why the two efficiency differences between PSU and battery exist,and will find that reason,while you(the pen pusher) will just keep on wallowing in your own self pity,and continue to peddle rubbish-like you are here and now.

For stooping to that low a level of trash talk, go foof yourself you semi-literate jackass. I can assure you like I said before, I can spin circles around you on a bench and its been 25 year now. As of a few months ago, you didn't even understand how a Joule Thief works, you did not understand how resonance works, and you did not understand how an inductor works. You could barely punch your way out of a wet paper bag. Look at what you posted to RMS seven months ago. You tried to make two points to him, and on both of your points you fell flat on your face, wrong and wrong again. That's really impressive "six years under your belt" bench work noggin shining there Brad.

Your bullshit pitch that I am lost and you are the one with all the answers when it comes to a Joule Thief is a joke. It's just you being steaming mad. This is your cue to mention a JFET fool.

QuoteSo i stand by my answer-->you cannot place an ideal voltage across an ideal inductor.
If you did(theoretically),the current would rise instantly to an infinite value.

But you were saying just last week that no current would flow because of the CEMF!

Time to crack another egg and put it on that piping hot skillet.

Foof?

I am not sure how dioxygen difluoride fits into it,but anyway

But i see it did not take long for those profanities to make an appearance MH

But if it makes you feel better,then you go right ahead,as us Aussies can take a whole lot more than you can give--were all convicts remember lol

QuoteI can assure like I said before, I can spin circles around you on a bench and its been 25 year now.

But alas -cannot prove it--even when some one else well gifted in the art of EE was going to do all the bench work for you.

QuoteAs of a few months ago, you didn't even understand how a Joule Thief works, you did not understand how resonance works, and you did not understand how an inductor works.

It would seem that you have made that assumption based on your own misunderstandings,and lack of knowledge. Kick back a while,you might just learn something

QuoteYou could barely punch your way out of a wet paper bag

.

I think i could manage that MH

QuoteYour bullshit pitch that I am lost and you are the one with all the answers when it comes to a Joule Thief is a joke. It's just you being steaming mad. This is your cue to mention a JFET fool.

Why would you think i am mad MH?
And i was not going to mention anything about you not knowing what a J/FET was.

Hang in there MH--we'll learn ya something soon enough-->hows that for some spot on English

But anyway,if you cant keep up,just do the best you can

Everything you just posted was completely FAKE Brad and you are not fooling anybody.

When push comes to shove you degenerate into this weak little fake character and I have no problem being completely real. It must feel miserable inside having to put up this fake front when you know that most people know that you are faking it. Go build a Joule Thief, it will be good therapy for you.
