Joule Thief

[TheNOP]

Energy is not what we have been taught  that it is
We need to  learn about it for ourselves .

please stop fooling with your mind.

be honest with yourself.

what did they teached you at school ?
what did you understood, retained, of it ?
could it be possible that you did not completly understood some parts of what they have teached you ?

do you really understand the laws pertaining to electricity and magnetism ?
what about those pertaining to physic and chimistry in general ?
how many of those were teached to you ?
did you specialised yourself in a specific field ?
ex: physic, chimistry, electronic, mecanic, etc..
if yes, did it helped you in any way or was it all bullsh** ?
do you really expect schools to teach you every things known to man in just a few years ?

if something has been tested to the point a law was devised, isn't it safe to assume that it does apply to what was tested ?


don't answere those questions to me.
answere then to yourself.

not quite true, it depend on what efficientcy he is talking about.
efficient at energy conversion or "efficient" in a way to say: you will have less problems at higher current with a DC - DC converter.

conventional DC - DC converters are far from having high conversion efficientcy, a bjt beat them at this.
but the same might not be true for jts with pickup coil(s).

he is right.
to charge a battery you actualy need to push charges(electrons imbalance) into it.

pulsing a battery will rise it voltage without adding much charges to it.

one thing i have learned about batteries is that:
you can have volts without apparent current and also can have current without apparent voltage.
when both are connected in series you will have an output that is not exactly what you would expect to measure.

the effect you are experiencing is due to the charges you put into the other battery, even if it is very little, and the properties of those chimical battery.
at relaxation time, a battery will regain a bit of it charge by itself.
this is due to the chimical reactions being slow to re-create electrons imbalance within the battery.

using batteries to test what you are testing is not a good idea, super cap would be better to test for OU.

i don't say that there is no usable effect with batteries.
but in a few weeks, if your system is not OU, you will notice that you will need to switch the batteries more and more often as the time pass.
with caps, you would see it way faster.

Thank you for the advice! Can you recommended some Super Caps that I can order online to test with?

I know this setup is not even close to OU no mater how much I would like it to be!! It is however far more efficient then what I have been seeing in my previous setups.

Thank you!

why not just shield them, or explore the helmholtz setup that someone (sorry, i forgot who it was) showed earlier?

I was messing with the notion, but ..shielding? ..is anything really shielded?

As for the helmhotlz idea, the principle is the same, the winding is 100% easier; I was attempting to remove the idea of using a toroid.

The operation is related directly to the spacing of the coils...as one might suspect.

i'm just saying, if a big jt put out enough rf to attract the fcc, it could be shielded to drop enough to where it wouldn't be a problem. i think.

was that you? sorry i forgot and was too lazy to go find it.

Gadgetmall is selling a very nice 650 Farad supercap on his site for about $60.00 or so.  I have ordered one.  He has the link to his site on the bottom of his posts so, if you want to look into it, just find any of his posts and you will see the link.

This may be too large a cap for your purposes but then again, maybe not.  If you got your device to charge this you could probably run the device for another week or more just from the supercap.
