Joule Thief

[guruji]

Hi Jeanna very interesting video of Project Camelot. I'm a novice in electronics but I want to ask about the outer casing of a capacitor;is that connected with the negative pole too cause I build the Jeanna light but this time it's not lighting my leds don't know why?
Still searching.
Pony try to replicate yourself before critisizing. Try build a bedini motor first as I did then move to more complex ones. Then comment on things but be practical.
Thanks Gadgetmall; Jeanna;Pirate;IST and all who's contributing to this.

         here is one of My liitle table Night lights i use and built several weeks ago . It uses one 4.7farad Dynacap .no batteries . i place it under a table lamp for 5 minutes and it produces light for over 27 hours .Funny thing that one light is lit when the supercap is full but as it approaches 1.8 down to .2 volts the transistor(germanium)fires the other two .5watt leds.Strange ?

Hi Gadget,
So, does it follow that I should get 5 hours from a 1F cap?
What is a dynacap?
I have the phillips 1F 5.5v computer memory cap.

I already had my hour of sun for the week and it is a very cool thought that 5 minutes under a table lamp will get this going for so long.
3 leds?

I have the jtc I made for the EB that has the germanium transistor.
I am assuming this will work?

ooo cool of it does.


So, I have a 2" square solar panel I got from you. I just hook up the leads pos to pos so it fills the cap? or is it pos to neg?
Then when the light is off it lights up.
Do you use a switch?

thanks,

jeanna

I am having trouble with your question/statement.
The outer case of a capacitor??

I am also wondering if the leds are all on the secondary-pickup or if some are still in the basicjtl  (I call it the 'thief') position?

great work ..

please watch this video i used only a 2n2222a transistor it has 60 outputs..

it is a tuned unit on the jt side .. not on the output side .. this coil was sent to new york some time ago ...

It is not worth wasting your time on them.  I seriously doubt that they would understand how to build even a simple JT circuit so I am done with any more efforts to try to educate them.  They will go away eventually, and they will have learned nothing, and that is a shame, but we can't change that.

Wow Bill. Those are serious allegations. I can assure you that understanding how to build a JT is well within the grasp of most folks here, including the ones you believe need educating. I think you can do a little better than that and give some credit where credit is due.

I give credit to all those that have made a JT and learned from it. However, it does not make me any less credible simply because I do not build one myself. Please do not think that the JT is an undiscovered circuit or device. It has existed in several forms for decades. Granted, you and other folks here may have discovered this novel version of it recently, but it is an old established technology (I'll try to find some old patents or design documentation).

The novelty of this variation of this common circuit, is it is small and purposely extracts untapped energy from nearly-spent batteries. There is no magic relating to the spikes that it produces. It does not charge another battery or capacitor (bcap or otherwise) for free. What it DOES DO (and I've stated this already, and it is clearly spelled out in the document I recently posted) is transfer the energy between a source and a load in a more efficient manner than is possible with a straight piece of wire alone.

I learned about this circuit myself almost 25 years ago. I do not need to build one to know that it works, and since I've explained how it works a few times now, it should be somewhat obvious that I already know that also.

i know better than to doubt you  however the answers that were revieled to me .. 

go way beond the jt ... 

thats just MY  tool to wake you up .. 

ist!
