Joule Thief

[innovation_station]

im just peeking in ... lol

but

i remember STEVEN MARKS.... saying something like ...   

i use a full wave silicon rectifier on the INPUT!  FIRST....  hummm
 

Y?

cuz he takes the ac off the small coil ....    rectifies it to dulsed dc and powers the big coil with it 

ist!


i got a picture up here SOME WHERE ....   from WAY BACK IN LORDS OF THE RING THRED ....  ..

I LOVE BRINGING BACK MEROMERIES.... 

same same ...   

well then ya kno ... ya get the ist magic feedback coil going on ... 

and well im at it lol you need the teteheedron ..  and inner circle   the outter will be there and free for use...

sheesh    ufo next??!!??


i add this pic ...  to visialize ...  not nessarly as showen ...

@ nievesoliveras

I think the idea of a diagram is great. This should help a lot. But, the diodes as shown in your diagram block both DC and AC from going through the circuit. They are equivalent to an open circuit.

This is just one part of this @mk1's circuit posted by me with @mk1's and @jeanna's comments here:

After we get clear this two coils we will go to the other two, then to the two used for the Joule thief. I do hope that you understand.

A graphic explanation of my first question. It seems that the other one is misunderstood.

The question is on the graphic.

...
Just save this graphic as .bmp and change it on paint with your ideas. Then save it on paint as .jpg and post it. I will do the same with your answer till we get it understandable for everyone.

Jesus

Perfect.

Thank you, Jesus.

AND your first 2 questions clarified my problems really well.

I will put the results together and post it sometime today... unless I find problems I haven't noticed yet.

@xee2,
I am not sure any more that I am putting the probe clip in the right position.

I read a couple of how-to web sites today on scopes and the red clip is pictured staying on the plug of the electrical output. No mention is made of the black clip except it can just hang there. (of course, I don't have a red clip. I assume this is because my scope is battery powered.) I assume the use of the black clip is, as you pointed out, to be used as the other probe against which the tip probe is measuring the wave.

The question remains, however, is there a place, using this drawing, please, of where the clip should be attached. I want it to be on the ac side of this circuit. I do not want to re-introduce any connection of the basic battery circuit back into my measurements.

thank you,

(anybody else want to help if xee2 isn't around?)

Jesus,

The problem I have with the use of clockwise and ccw is that if the viewer moves to the opposite side the direction changes. If you could greatly magnify the drawing, or better yet use a magnification of the MK2 as I did yesterday. I changed the names adding more names, because it only confuses us to have any names repeated but for different parts.

At the bottom of the MK2 is a clear drawing of the coils and their directions.

Anyone who has made one will be able to immediately know what the lines mean and the questions about the directions becomes very clear.

I think we should assume that someone has one to look at for reference.

A washer with string wrapped around it is enough to make a difference in following the questions.

I might put up a drawing that can be used for changes along with yours. for now, maybe

thank you so much for stepping forward.
