Joule Thief 101

[MileHigh]

Are you claiming that it will NOT?
Ye who owns not a Joule Thief?

The claim from Brad is that it WILL.
Let Brad back up his own claim.

What I mean is-lets not waste time on the VR , and how we can increase the current flowing to the base of the transistor, as we decrease the base resistance ,which switches the transistor on harder and longer, resulting in a pulse width increase, thus maintaining a magnetic field of the same value as the battery voltage drops, which in turn would maintain the current flowing through the LED to be around the same value, resulting in the same light output from the LED--as the battery voltage drops. Even though that is just a quick and brief explanation, lets not worry about that, nore the fact that the ! So called! sweet spot could also be maintained as the battery voltage drops by decreasing the base resistance. Lets not worry about any of that--lets do a MH on this one, and give everyone here time to throw away all they have learned, and wait 4 to 8 weeks for my theory of everythig-where I take a 20 minute googlegasm, and present world changing determinations--this is the MH way.

So, you have given your answer.

- the transistor will not switch on "harder," it is already ON.
- the transistor will not stay switched on longer, you are making a totally blind and completely wrong assumption based on your false belief that the transistor has been switched on "harder" and "'harder' equals 'stay on longer.'"
- since the transistor will not switch on longer, there will not be any "maintaining a magnetic field of the same value as the battery voltage drops."

So, you are showing the world that you don't understand how a Joule Thief works.  You are showing the world how you made a blind "Doh!" assumption that lowering the base resistance would increase the brightness of the LED.

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.

My ass, you clearly don't know what you are talking about.

Ha ha, why does that comment make me think about a Dr. Demento novelty song?

Still an Idiot, no wonder no one takes you seriously!
