Joule Thief 101

[tinman]

As far as just about all of the content in your two postings goes, you can sure lay the poseur BS on thick when you want to.  It's like watching a bad actor in an amateur theater production.

P.S.:  The only feelings are frustration because of the willful ignorance.

That just shows how linear and insulated your thought patterns are.

And how un-definitive your question was.

You have made a claim that you understand how a Joule Thief works at very low voltages.  I am calling BS on you.  Tell me, what determines the operating frequency at very low voltages?

Once again-another question that cannot be answered without further information--like i asked for before,and you refused to give.
Transistor type
core type,size,grade
wire size,turn ratio
supply voltage that can be delivered without drop
LED type and specifications-->including internal resistance lol.
The list go's on MH

EMJ did not fall for your trick's,and i gave you the answer your question deserved--it's that simple.

What else do you get when you supply a DC voltage to a coil of wire MH ?-other than dissipated heat,and a magnetic field that dose not vary in time. Perhap's it's time you answered some of your own question's.

Says the man that refuses to even have a go at decoding Mag's low voltage scope shot,and who laugh's at those who say LED's have an internal resistance that can effect the operating parameters of such a circuit. You dont even have a go at answering the question about the LED's internal resistance i asked you-even though i gave a graph for you to go by.

And you call me ignorant  .
It is funny that you want everyone to answer your question's,but you dodge all those ask of you.

I didn't even ask a question about the voltage source and the coil that I made reference to about EMJ.  Work on your logical thought processes.

The last time you tried to back out of doing some circuit analysis I told you that you didn't need specific component values or if you wanted, just plug in your own values.  You didn't say anything and you ran away.

You are trying to pull off the same stunt this time.  It's obvious that you have no clue how the Joule Thief operates at very low voltages and why you would even claim that you do is almost unbelievable.  You are not fooling anybody - you clearly do not understand the operating mode of the Joule Thief at low voltages.  You are just being a clown.

There were no tricks with respect to EMJ.  He could not answer a question about the operation of a circuit that consisted of a voltage source and a single coil.  He threw everything he could at it and just about had a meltdown.  He was a fraud preaching about coils when he didn't even understand how one worked.  With respect to the Joule Thief at low voltages you are clearly in the same boat.  You are bluffing when you ask for component specifics, it's a farce and you can't admit that you don't know how a Joule Thief works at low voltages.  Why should anybody take you seriously when you spout this kind of nonsense?

Yes I refused to have a go at decoding the low voltage scope shot because I am not interested and it would take a lot of work on a bench probing the circuit and going back to reviewing how a transistor works at low voltages to figure out how the circuit actually operates.  But you the faker claim you understand how it works and when you are asked how the operating frequency is determined you choke and say you can't do anything without component values and it's all ridiculous bluff - you don't have the slightest clue how the Joule Thief operates at low voltages.  How can you actually make such a ridiculous dishonest bluff in front of your peers?  You are a walking three-dollar bill.

The question about the LED's "internal resistance" is a complete farce considering how you know I have been around for years.  It's a complete farce since a few postings before that in the thread I made a comment about the various ways to look at an LED in terms of resistance.  It's just you being a poseur and a pretentious clown.  You should be embarrassed by your ridiculous nonsensical behaviour.

Says the man that has no idea him self-->but still can argue that my presented operation is wrong . That is truly laughable MH

Oh dear.
Tell us all here how the internal combustion engine works MH,and what RPM it will be capable of achieving. Im not going to give you any specifications about the parts used in that engine,nor will i tell you if it is a gasoline engine,or a diesel engine. Im also not going to tell you whether it is a piston engine ,or of a rotary design-->but i expect you to be able to tell us what will determine the RPM of the engine --much like you asking me what will determine the frequency of a JT circuit without any component specifications.

I see once again,you have failed to answer your own question.
Tell us all MH, what is the result when applying a DC voltage to a coil.
As that is all the information you gave EMJ,then i expect you to answer your own question with your given information.

With respect to the Joule Thief at low voltages you are clearly in the same boat.  You are bluffing when you ask for component specifics, it's a farce and you can't admit that you don't know how a Joule Thief works at low voltages.  Why should anybody take you seriously when you spout this kind of nonsense?

Here is a fact MH. I have done a lot of work on low voltage oscillators,and i do know how the transistor is working when the supply voltage is lower than the required voltage to switch on the transistor. This can vary with different types of circuits. You on the other hand,admit to not knowing how it work's,and yet believe you have the right to pass judgement on others theories.
I DONT KNOW HOW IT WORK'S-BUT IT DOSNT WORK LIKE THAT.
  See how silly you have made your self look MH

I didn't even ask a question about the voltage source and the coil that I made reference to about EMJ.  Work on your logical thought processes

A clear admittance to not giving enough information to make a correct analysis.
You do this quite often,while insisting that others give accurate and correct information about there experiments--like dots on coils of well know circuit's--> saying one schematic is different from another because it has a 10k VR--although you have no idea as to what resistance value the VR is set at.

These are fact's about you MH,and they have all been displayed on this thread.
You are a true example of a hypocrite --expect everything from others,and yet not even willing to answer your own questions.

I once had respect for you,but that has all faded away now that i have seen your true colors.
