WAYDAGO!!
very nice. Don't you love it?

How many volts did you end up with on that fatso winding?
And, did you leave it on to see how long you can use it?
I think one of the telling parts of our designs is not just how long it will last using one AA battery but, what the dead battery state is?
That means you must be there the moment the light goes out to check the dead voltage level of the battery.
(the reason for this is that the transistor will continue to drain the battery even though the light is off.)

Please share this info, because we all need it.

Thank you.

Hi jadaro,
The part you are forgetting here is that each transistor will drain the battery a little more and the C-E junction is a very expensive place to put your light.

There is not really a tertiary winding because the primary is actually just a center tapped single primary although it is written out as a 2 wire thing and can be made to seem that way.

What you are calling tertiary is really just a secondary.

The cost of using this is about the same and sometimes LESS than just using the transistor for the fraction of the time it is on.

OK, so I am really frugal, but in this ou endeavor, that kind of frugalness may make the difference.

thank you,

thank you both

jarado2600 ...  you bring up good points ...  as i beleave ...  there is more to be discovered ...

like 2 switches 1 line ...... 

but aside that for now

GREATWORK  GURUJI!!

sure is bright ..

there many aproches to the same result..

my aproch is diffrent than everyones in my opinion..  i dont want true perfect resonance like a tank like tesla don smith .......  all of em .. 
and this is where being cheep DONT PAY ...

ill tell ya why ...  infact ..  1 of TESLAS experiences .. he was tuneing and noticed the thunderstorms .. / solar storms?  flares to be exact !  compleatly destroyed his toys 

wakie... 

so assume you make the perfect most efficient device .. you  now have the most perfect thing .. so

when you go to scale this up because you will want to do so ... the first hint of geo magnetic distrubances .. poof there it goes ... 

i like my designs ...  i like to use some power ...  and get some more back ... im not at all concerened with how many watts my units consume ...

I do agree.
I also find it then purposely go off resonance, because I want more resilience.

This gives me a great chance to say what my approach is.

I am looking for the ways to start with a simple pulse and to manipulate and amplify the results to a level where we can use it.
So, frugalness comes in here not as a philosophical method, but because it is necessary for me to limit my input to a series of pulses, because I am wanting to find a way for just those pulses to create useful energy.

If I add too much more I may miss a way to use a very limited supply.

I hope this is not too confusing, but I thought it would be a good moment to mention this.
Thank you for the opportunity,

jeanna

sounds like you need a chord that will cause rotation ....
