Joule Thief

[osiris]

It is not an unusual occurrence... most capacitors will "appear to recover" a measurable charge after being discharged. What you need to demonstrate here is how long  your capacitor can power the LED's for _ compared to the time it takes to recover sufficient charge and energy for the process to continually repeat itself without interuption!!

humm  is that right ..  ?
i simply need to take as i have showen in the video ..  and fill a supercap with a jt insted of burning the leds .. 

simple eh! 

think ya can do it ? 

i have

regards 
osiris 

it is ovious that if it powers 4 leds .. it will run  almost any  joule thief  what ya think ?  i said i can DRAIN OUT THE CAP VIA LEDS AND IT REFILLS ITS SELF THEN I CAN REPETE   ok

so what if it takes 24 hours to gather enough free energy to fill the cap the first time ! so what .. after it is full  the rest is free

get it ? now if you want me to be a smart ass ... i can   

throw a solar on it to fill it the first time .. now it is really fast ! and cheep

Please help me check whether i label the transformer pin correctly.. I couldnt get my fuji work, so i remove all component out and connect using wires. But i try the pin transformer according to josepino diagram but couldnt get it right. Please help. Thanks!!

btw, Merry Christmas everyone. Have a nice day!!

Now some transformers come with the windings different.
Where suppose to be a 1 there is another number.

You have to check continuity and sketch a schematic of the transformer you are using.  Maybe you have to take out one from another fuji and learn from it by measuring.

Please try taking out the gds and the neon bulb and try a blown LED in its place as an antenna.

Hi Jesus,
I did what you suggested. I blew a led purposely for this experiment, and then connect it to the circuit. See the attached photos. No improvement. The load( a big LED) kept drawing down the battery. I tried with cap paralleled or seried with the blown led antenna, and nothing improved.
Any ideas besides everybody to help this to work out?
Thanks and happy holidays!
