Joule Thief

[jeanna]

More interesting stuff.

Earlier today, xee2 suggested to me that I should take windings off my secondary/pickup coil to see when...

Also, MK1 suggested hat I should turn the led round if it goes out when I add the 2-y/pickup coil.

So, I made a breadboard with a joule thief with 11 turns as yesterday.

I understand from MK1 that testing with a voltmeter isn't going to show me much, so, instead of looking for when the secondary coil produces 4 volts as xee suggested, I stuck a led into the other side of the breadboard, and sanded the ends of some mag wire.

AFTER ONE TURN of the mag wire around the toroid, the second light went on when I touched the leads.

(the first light went off also so, I turned it.)  And now, after only one turn I have both lights lit. I am going to push this a little. I will do the bridge thing later... this is way too much fun and my AAA is not fatiguing . HA

@Amigo

I saw your posting on led and power supply for neon, thank but honestly did not want to read it , since i am the type of person that needs to experiment and make my own idea , and having a new point of view , i think that slowly learning and allowing people to make mistake , will yield different result , and mistakes that would not be done by well trained and knowledgeable people do.

And by taking it step by step bring unity from chaos .

Discoveries are made by mistake so lets make some.

@ Jeanna:

Great work!!!  Nice job figuring it out.  I am having big trouble keeping up with this topic.  I guess I am about 4 pages behind now but I have hours of paperwork to do from today's activities so, there is no telling how much further behind I will be.  I want to get up to date with my work and then when my other stuff comes in, I might have some time to experiment.

I owe a lot of you a lot of responses and I WILL get to them.  I just really appreciate everyone's attitude on here and all of the help given to others (like me) that need it is also greatly appreciated.  Great things can happen this way.

   But Pirate, I thought all PI's had secretarys to do all the paper work for them.

That is why I flunked out of being an office worker. I was made a file clerk and that
lasted about a month and I told them to shove it. Got to get my hands into things
that work and move.
