Joule Thief

[TheNOP]

This particular setup is running at around 2.5MHz...

how did you found that, you have a frequency counter ?

[jeanna]

OK,
I see.

Still, it is the second tier that has the smaller ratio. I don't remember what. I suppose I will need to know when I am trying to fine tune my circuit.

for now, I am still just doing primary information gathering about this novel circuit.

thank you,

i'm done with this forum. stephan removed a post of mine on his 'be a vegetarian' thread. absolutely unacceptable.

nice meeting all of you, this is the best group of people on the board right here.

if you understand RC circuit then you can reproduce gadgetmall results easily.
if not, you will need a lots of experimenting and a lots of logic to repete it.
and if you can't think logicaly, you might never be able to replicate it at all.

same thing goes with the cores
if you don't understand core's limitations and how to set the transistor's frequency you will get "bad" cores and not know how you can fix it.

theNOP,
Half of the people working on this thread do not have a great deal of experience or knowledge about these things.
We are here to learn, and to help each other.
We are also here to share our experimental ideas and results with each other.


Perhaps it is time for YOU to share some of your experimental results with us.
You make it clear that you have already tried and therefore you understand the things we are doing.
Since you have such great understanding I think it is time for you to take a turn and share your experimental reasons for saying the things you say.

For instance, what experiments did you design and perform that have taught you about toroids and their potentials.
What experiments have you made with RLC circuits.
Did you have any results?
What (exactly) did you find?

I am talking here about joule thief related circuits.
Have you made a joule thief circuit?
Does it light up your house at night?
Did you use a cap at the base?
what transistor do you find works best?
How many turns on each half of the primary jt winding do you prefer and why?

All taken from YOUR experiments, I mean.

Thank you,

jeanna

Wilby, you are a valuable contributor here...perhaps it was simply a mistake.

Please explore that possibility before leaving.
