Joule Thief

[resonanceman]

I just thought  I  would   post some stuff about my latest non toroid JT

It is made from a transformer  I found  in an old monitor .
I have no idea what this  transformer is  designed to do .

The  picture  is of the bottom of the  transfomer.
I drew lines  between  the pins   that   conduct

The  high voltage is a around  260V    It lights up  my  90 LED array  bright enough that   it  makes me  worry about it burning out in a few minutes .   It also sings . With  normal  wall power the array is silent  .   it  sings pretty loud with this  transformer ......even at  less than  max  intensity .
It  also seems to  interfere with my wireless mouse  a little .


The  feedback   charges  a bridge /Cap  to 26 V   
Iff  hooked  directly to my Jesus charger  the LED array almost goes out .
Placing  a  cap  in  series  with the the  Jesus  charger   limits the  current for  feedback
I have not found the  exact cap  yet .    1uF   is not  quite enoiugh  2uF  draws to much .
I am  pretty  sure that  with the right  cap   this  thing  should   self charge .

i have another video im gonna edit ...  this will demo a darn kool effect you all will find intresting...

i used a coil pictured on ou here in the video ...  if i remeber correctly sparks  rymed out the idea .. im not sure yet ... tho

fact is it dont matter ..well worth what you willl learn if we can apply it .... it would be great!!

i used a freq genny on the coil to 180khz...  and then i touched the one lead then touched the other .. out put grew a lot ...



ist!


HERE IS THE VIDEO I MADE ...

I bet you're right.
The right cap. I need to go to RS and pick up their mixed cap set. I always thought they were too small value, but for what I was doing yesterday the 100pF did the job. Next will be some supers. I have the slow super caps but I want to try some fast big caps, like 1 or 2 uF or mF or even F. Whatever it takes, I am going there.
How do you raise 30mV which fluctuates at 2.2Mhz to something useful. Something that will run gadgetmall's air conditioner?
A tank running off these fluctuations with inductors in stages, maybe.

hmm

But I digress,

What is the B+ in your drawing? Base with resistor attached?


@Gadgetmall,
Dig a hole 4' x 4' for a water tank and cover it.
Slip into it a roll of hose or main-waterline- tubing. Run the tubing from one side of the window through the water to the other side of the window. Blow a fan into a funnel so it forces the air in or maybe suck the air through. It will be very much cooled as it passes through the cold water in the tank and cool off your room for the cost of materials and running the fan.

Can you point me to any places better than/ or in addition to  Barrys coilgun site or crystal radio (which is sometimes off) to get instructions on how to use inductors and to match them with capacitors?

thanks,

jeanna

Way to go man!!  Very nice work.  I am glad you stuck with it...see...your persistence paid off.  That is a very nice looking Tesla coil and now, it is lighting an led.

Excellent!

Thank you @pirate !

there is a formula used to get the value you want. I dont have it now, I dont remember if it is parallel or in series.
The truth is that when you enter a value you want, the formula gives you almost the exact 2 capacitors values you must mix to get the value you wanted.
In that way you can use a value starting from 1.10uf for example and keep increasing the value till you get the 2 capacitors values that will make your jt selcharge.

The pvc battery holder is made with 2 neo ring magnets with wires red and black attached, then passed through a small hole on the pvc.
Put the battery inside with one holder terminal already in its place and then include the other, it will adhere to the battery and it wont loose contact if the neo ring is properly tied with the wire.

Maybe I won't give up on it yet, but when I turn the power supply off....no more voltage.

Yes! Do not despair. If you get tire, make a cup of coffe or a cold drink, take a walk and the idea will come to you.

It could take a while but the idea will come.
