Joule Thief 101

[hoptoad]

Go ahead and answer the simple questions about a resonating wine glass and show us your smarts.

I've never said I could or would answer your questions, or even rise to the challenge of trying.
But I have asked you to answer your own questions. However I'm quite content to wait for your answers in 'X' many weeks.
Your response to ramset indicates you seem to be incapable of simple yes or no answers to questions that only require a simple yes or no
for an answer, so I'm predicting your explanation will be a word salad. It will be a nice surprise if you prove me wrong.

Yes but part and parcel of that is "Have you ever built a resonant device?" is a useless loaded question.  Have I ever had any reason to build a resonant device?  The answer to that is no.  Do I know about resonance and how to stop it on a PCB signal trace?  The answer to that is yes.

It's just too easy to plant a loaded question and gloat over it.  The real purpose for this is to learn about resonance and how to see it in our daily lives and describe it and understand how it works instead of it being a near-meaningless buzz word where many people don't even understand what it means.

Hypothetical example:  Bill Alek has a magical regenerative battery charger that is supposed to be able to make an ultra cheap electric bicycle from China that he wants to resell run indefinitely.  He claims that it is all based on resonance being used in his magic regenerative charge controller.  Bill Alek is interviewed on a trade show floor by a young university student and the university student asks Bill Alek to start off by explaining what resonance is by explaining how a wine glass resonates and how the resonant frequency of the wine glass is determined.  Bill Alek is stuck and he doesn't know what to say and asks the student to stop recording.

I did something like seven or eight courses in electronics more than 30 years ago.  I make no apologies for not remembering what I did in each of my electronics labs so I gave the best answer that I could.

Sure Brad, "charge flows into magnetic centers."  That's a new one for the "Bizarro World Book of Brad's Electronics."  LED's running off of "core halves."  You were challenged on these crazy statements and made no attempt to explain yourself or offer any insight.  All that you could say is that you were right.  Another total fail and another case of don't go to the EEVBlog unless you want to be eaten alive.

You want to prove that you have learned something about real electronics over the past six years?

This:

So let us know precisely why a Joule Thief needs a variable base resistor.

If you ignore that one more time and can't back up your own statements with a comprehensible and rational explanation that is rooted in real electronics, then that makes you a fraud.  The assumption in this case would be that you can't answer it and refuse to state that fact.  Thus making you ignorant about a lot of basic electronics and also a fraud.  On the other hand if you answer it properly or simply admit that you can't answer it, then you are real and all is good.

I just find the fake three-dollar-bill aspect to you to simply be too much sometimes.  Rest assured though that this is just a side-show to see if anything comes of the "Resonant Joule Thief."  I won't be interested if you disassemble a dish washer motor to do more "Brad's Electronics."

Yawn.

Sure Brad, "charge flows into magnetic centers."  That's a new one for the "Bizarro World Book of Brad's Electronics."

So a man that dose not know what the magnetic force is,is also an expert on what it is not
Much the same as a person that dose not know what a car is,but is an expert at driving one lol.

If you ignore that one more time and can't back up your own statements with a comprehensible and rational explanation that is rooted in real electronics, then that makes you a fraud.

Oh so you are the decision maker around here now?.
And now,if some one dose not answer your questions on demand,then they are a fraud lol.
Get over yourself MH--you are nothing of a sort--in fact,you are falling further behind with every post you make.
It's not that i cant answer it MH,it's just that i choose not to simply because you demand me too lol.
So no--no answer for you MH.

I won't be interested if you disassemble a dish washer motor to do more "Brad's Electronics."

Motor no longer needed.

LED's running off of "core halves."  You were challenged on these crazy statements and made no attempt to explain yourself or offer any insight.  All that you could say is that you were right.

Only crazy to you MH,as you just cant follow simple instructions.
In fact,you only need a laminated core,and either a ground or hot connection. The LED can be lit from either the insulated core(laminated steel),and the ground side,or the core and the positive side. Or as i said,you can have two core halves (insulated from each other)within the conductive coil,and when that coil is pulsed,the two core halves will develop an opposite charge,and you can lite an LED when placed across those two core halves.
Like Webby said--dont you know a capacitor when you see one--dont you understand how the two halves are charged with an opposite polarity?.

Hence the question MH
-->What is the magnetic force?

 

Another total fail and another case of don't go to the EEVBlog unless you want to be eaten alive.

Dose current flow through a capacitor MH?.

So, you are exposed as a fraud and a BSer.  You can't answer the question about the supposed need for a variable base resistance for a Joule Thief and refuse to state that fact.  It was all just a bunch of BS and you haven't a clue about the basic electronics required to answer the question properly.  So the only solution for your original BS is to BS again.

Your can't back up your own statement, "Do you need an answer to understand the need for a variable base resistor MH?-or will your batteries simply remain at the rated voltage of 1.5 volt's?. That was a bit of a silly statement by your self MH."

The whole thing was just a bunch of BS and you thought that you were "smart" by saying you needed a variable base resistor.  You have been exposed as a fraud that makes BS statements to give people the impression that you know what you are talking about when in many cases you don't and it's just bluffing.  Who is making the silly statement now?

For the "charge flows into magnetic centers" we are back in Brad's world of random stream-of-consciousness, thoughts ricocheting all around like a bowl of agitated spaghetti, and extremely deficient communication skills and flat-out laziness to try to describe something properly.  It's like watching a Brad clip with a 10 minute introduction where he goes over 40 alligator clip connections to "give you the schematic."

So that's the ticket, you need to buy the "Super Brad Secret Decoder Ring" for this one because the regular secret decoder ring is not strong enough and simply can't unscramble the words and turn them into a coherent set of statements.
