Joule Thief

[gadgetmall]

I have a suggestion for your earth battery to run the jt . Try different electrolytic capacitor values across your EB wires . Seems 2200 uf comes to mind low esr  . this will give your eb a boost .

Gadget,

Nice to you see you.
You don't know me, but suffice it to say that I am a fan.

You said,
                    Basically, I would like to know your opinion.
        How important are these two phenomena to you circuit designs?

                        1. Resonance.

                        2. High Ferromagnetic Permeability. (a high concentration of rotatable magnetic dipoles in the core)

I have deduced that these are vitally important to making an Impressive Joule Thief.
Do you agree ?

Well i have all but lost most of my mind and energy but if i remember correctly member jeanna went thru the whole permeability verse power . People here have made good Jt's with nails , air core , low perm ,ferrite radio rods toilet paper rolls(mk1)  . hard to say but i personally find i can get the toroids which are expensive and high permeability to put some serious power out . They are easier to work with and also  the bigger ones are easier to wind . I look at it like a bell the bigger  the louder . Resonance in my opinion is my key to producing the maximium output while lowering the input . picture a block of wood and strike it . Thump! now the same for a piece of metal . Ding! I know i don't make any sense at all and i shouldn't be typing on these meds i have to take including maranol . . Its just been a few good days for me in a long time to sit on a keyboard or even be up during the day before my daughter gets home from school . I would say without stepping on anyone's toes that i prefer High permeability than low and resonance is everything and one of the reasons i used tanks in the older circuits . . I have some really big high perm 7 and 9 inch toroid s and they can produce ten times the power of the one i showed with much less wire and tank components other that wire  .I miss Alex . I dont know if you know Groundloop but he much Smarter than i could ever be and i almost bet he knows the answer . He one heck of a tecky and i am grateful i had the pleasure of him actually helping me on one of My projects . I was the guy who had stuff and hooked it up any and every-way i could till something good happens:) This included even parts placement even has an effect as well as magnets on a Jt I even experimented with germanium can transistors and cut the tops off and filled them with Barium powder and cooked them to make a better transistor bad mistake and i was right there smellin the smoke from em so in a lot of ways i just aint right but i try and you know what it works and some of those transistors produce there own power and lower the bias as low at 0.200 volts to make them oscillate
. Good to meet you sir have a wonderful Christmas and what ever endeavors you do i am sure you will succeed .

Gadget,

Thanks for your prompt response.

You said,

i prefer High permeability than low .
I have some really big high perm 7 and 9 inch toroid s
and they can produce ten times the power of the one i showed with much less wire

That is what I would expect.
Why?... because the rotating magnetic dipoles
                                            powered by unpaired infinite electron spin
                                                              contained within any Ferromagnetic Substance contribute to the energy output.
         --> see diagram below <---

Could you please articulate what you think about the phenomenon of resonance?

Thanks for the well wishes... same to you but more. ;o)

The problem that i was facing is that i thought my JT is not working but actually it does work. It work with 1.5V battery but when i connect JT with my earth battery, it cant work.

The situation is like this:
1.5V battery with JT can light up 5led <-- this is to proved my JT worked

My earth battery(around 12V, 0.3mA) without JT can light up 5led(low intenstiy)

when i connect my Earth battery with JT can only light up 1LED(damn low intensity). When i try with 5LED, nothin happen.

May i know why?? It seem like when i connect earth battery to JT, the voltage drop. But it still work on normal battery.

I agree with Gadgetmalls  answer
A capacitor is your answer.

To explain a little more........ your  earth battery has a pretty good output.......but that output is continuous.
It is enough to light a few LEDs
A JT works a little different ........it is pulses.
The JT may take less power overall ..........but when it turns on......it turns on hard.......the transistor conducts alot for a very brief time.
It is that brief high power pulse that is giving you problems
A capacitor  across the battery will allow the earth battery to continuously charge the capacitor........ the capacitor  will then provide a flow of energy with enough depth to handle  the high current  pulses


gary.

i Almost cracked a smile . OMG i almost forgot him and now...

Unfortunately to avoid controversy the secret will be buried with me  but it's not ou its conversion of energy from one kind to the other  . And also all the info is in this thread to build one .there are no hidden parts and was wound to meet the resonance of the transistor with the Torroid which is high perm .There are no caps but there is two components that are simple . I as others found that Current in is decreased as the draw from secondaries increases so i have one winding that is dead shorted , Its a secondary that is a coil of wire connected together and the other component is a tiny magnet on the opposite side of the toroid and transistor .Magnets act funny on a torroid i found and they actually detune a circuit from resonance so my thinking was detune it with the magnet and retune it with the wire length not using any tank circuit but the wire it self . The whole thing was then dunked in Rubber latex . The black tape holds the fragile secondary wires to my female plug  to keep them from breaking . The Components are outside for access . I built this maybe 15 months ago ?  You all keep on building them bigger and better and have  a MERRY Happy Christmas .

thanks...... I will see if I can make something similar.
I guess I agree with  your view of what the magnet does........I have played with them a little........I did not find any extra power because of them........mostly I noticed that the JT started up at a higher voltage with magnets attached........
