Joule Thief 101

Brad:

Please go ahead and explain how a standard Joule Thief works and explain how lowering the value of the base resistor as the battery voltage drops will make the LED brighter.

Oh no you dont MH-->get it right.
I clearly said !maintain same brightness!--not make the LED brighter.

I will answer your question in 4 to 8 weeks,in the hope that it gives you enough time to use your own smart's,and work it out for your self.

Now--have you any thoughts on what the magnetic force is yet?

Yes, that's actually what I meant.  If the LED is going to dim as the battery voltage drops, then "making the LED brighter" will indeed maintain the same brightness.

Now we are talking real electronics, and I am asking you to back up your statement with a proper explanation discussing the electronics of the Joule Thief.  This is not the time for games, this is your claim - you stated this, and you need to explain how and why lowering the base resistance in a standard Joule Thief will maintain the brightness of the LED as the battery voltage drops.

I am not interested in talking about the "magnetic force," I want to hear you back up your claim and prove that you are supposedly correct by discussing how the Joule Thief operates and how lowering the base resistance will do what you claim it will do.

Nonsense, I am asking Brad to back up his own claims about the Joule Thief.  That's is the subject matter of this thread.  Stop your ridiculous BS.  You are fully aware that I understand electronics quite well, stop the nonsense.

[MileHigh]

Will you stop this foolishness right now?  This is the third or fourth time you have done it, and it's enough.

Brad:

We are discussing the Joule Thief and your claim about the variable base resistor.  I am asking you to back up your statement with a proper explanation discussing the electronics of the Joule Thief and how it operates.  This is your claim - you stated this, and you need to explain how and why lowering the base resistance in a standard Joule Thief will maintain the brightness of the LED as the battery voltage drops.

I want to read your argument and see you make a solid technical case by discussing how the Joule Thief operates and how lowering the base resistance will do what you claim it will do.
