Jeanna:

Very well done!  I hope everyone here watches your video series.  This will help many to learn about these circuits.

Thank you, Bill.

And now...

part 3 finally:

In this part 3, I started with a fresh breadboard and added pieces. This way you can follow what I am describing better.
I put the scope on the 2 secondaries and showed the output with different lights and resistors.
And, I showed the first problem I encountered.

This is over 8 minutes long, so be warned... I need to let them buffer when they are 8 minutes long!

I hope you enjoy it.

I have been trying to reply to your message and the system does not allow replies.

I saw your explanation and what happens at the end is what has been happening to my joule thief too.

The first component you placed on the breadboard, I could not catch what it is. Remember I can understand the written language more than the spoken language.

It helps a lot to understand your work !

This is so strange. The same thing is happening with protonmom. Yet, others can reply. Oh well, I am glad you replied here.

I will be making part 4 today. In that, I will show where I have placed the inductors. It is the inductors which keep all the lights on at the same time.
Then you can read some of the posts here and maybe they will make more sense.

The first component you placed on the breadboard,

This is a 1k potentiometer. I called it a 'pot'.
In this circuit it is made to be 246 ohms.
Then I added a 2N3904 with the flat part facing the camera.
Then a led
then the 'xtree' toroid.

[I know better than to call it a pot. I try to make my posts with normal english so non-english speaking persons can translate them, if necessary.
Please accept my apologies.]

I ordered an LC meter and until it arrives, I will not change this circuit.
but, I will make another video to show the solutions I have found, and do more datalogging, but no more with this circuit until then.

Thank you for asking,

jeanna

Thank you @jeanna !
You dont need to apologize.
