Joule Thief

HI . remove the red and black wire . not needed . also you cut the correct diode but you need to jump it with a piece of wire . this along with the  the trigger transformer ( the one in front of the diode )can be removed . then one more thing is a resistor that is between the trigger transformer and a silver Hv capacitor . this is where you put a variable resistor in place of that resistor . you should light a cfl easy if you do these modifications to that aaa fugi . The CFL tube must be removed from the screwin electronics if you are using a spiral cfl . Or use a florescent tube and the connections are where the high voltage capacitor were . this is your output . it is HOT so be careful and dont kill yourself

Thanks so much for such a detail explanation.  So i have draw out all modification that i need to make. But i still cant understand some parts.

Jumper wire, i connect the jumper wire from diode leg i cut to where?

Did i get the correct trigger transformer that u have mention?

And i need to replace resistor between silver cap and transformer with variable resistor. Can i know which type of variable resistor u refer to? I google it and find quite lot of range of variable resistor

i removed the 4.7m resistor. Should i put it back?

and finally, at which point should i connect the output to cfl?

Thanks

Charging capacitors is not that easy at first to try and understand... so don't worry.
Lets look at it this way, your JT outputs a certain voltage and current delivery capability. Lets say its a constant slow drip... drip...drip, if you place an egg cup under the drip it will take X time to fill up. As long as the drip is constant it will take the same amount of time to fill... OK. if you tip the egg cup, the contents will spill out and empty quite quickly. Look upon your egg cup then as a small capacitor of small value. Next repeat the same experiment but instead of your egg cup use a larger vessel say a large bowl. The drip remains at the same fill rate as before, but now the bowl takes a lot longer to fill up, like wise if you allow it to empty at the same rate as the egg cup it takes a lot longer to empty due to its volume (capacity) of water, but you also have a greater volume of water to use and do more work with. All capacitors charge and discharge at a rate determined by what is known as the time constant measured in seconds = the product of the circuits resistance (ohm's) and the circuit capacitance (farads)
t =RC. I hope my simple analogy goes towards a better understanding. Note of course we are dealing with a JT circuit and have to understand that the JT produces spikes of pulsed DC and as Bill has discovered additional pulsed energy which has further increase the voltage charge on his EB cap's. If you are not familiar with Ohm's Law or time constant RC circuits, take a little time to search the web I'm sure you will appreciate a better understanding and will help you move forward in this fascinating thread.  Merv

Thanks for advise ya!! I start to get what u try to convey here.. Seem like more and more thing to learn ya..  google right now to get more info on it

Hi, i actually have try according to link u provided. But problem is i still cant light it up. There no output at all.. Would u mine to post up your circuit? thanks
