@ Gilobob

So I can use a cheap solar phone/ipod charger or just hook it up to my PC. Just now I'm Charging a Big 12V 400A batt. With this JT i can charge all my batts that I got.

Thanks for reading the pages before posting. I think that hooking a JT to a PC is a bad idea. The JT sends large spikes back into the battery. The USB port is not made to handle this.

i think it is also a bad idea to call bad ships in the night!

of course i know  ... 

for your own safety i ask you stop calling them ! 

i hear they dont like lould whistels.. 

if you do not understand what im saying fine ...  it is because it is not you calling them

if you know what im saying...  then it is best you stop ..

As if to emphasise my argument on sensible moderation, IST compiles yet another unintelligible post of garbage:

And you folks have problems with my rebelling against this sort of insanity?  Why? What is wrong with you people?

I think the attached chart shows the effect of different permeability. The W material has a higher permeability than the J material. Z is a measure of inductance per turn. Notice that below 2.5 MHz the high permeability material produces more inductance per turn where as above 2.5 MHz the lower permeability material produces more inductance per turn. The material is selected which gives the most inductance per turn at the frequency of operation. For Joule thiefs, the frequency is in low KHz so the W material is better for JT.

EDIT: The J material will work in JT but it will take more turns than the W material to get the same output voltage.

im not being rude ... 

but honestly farra ... do you live in a box?   

have you not done any serches on the net ...

i think if you did a serch you would eat your words...

people think that what they are doing is a good thing calling things...  yet they are afriad!  fear is a form of control ...



as is love ...

i have come to the conculsion any core can be tuned to its max output ... then more coils can be added  i also find that when running at its natural running freq .. is a good place to start...  then seccond freq pulsing  syncing with earth will give EXTREAM RESULTS..

you are pulseing at its natural resonance ...  detirumaned by the wire length and the core resonance ... when you cut the pulse ... it returns A FLYBACK RESENANT MIRROR  of what was sent in .. IN  a much larger out put ...

hope this helps...
