Joule Thief

[Artic_Knight]

is that a 555 timer setup on the led rope lights?  the joule thief is not a curcuit you see in electronics usually but a 555 setup would be the same essentially. well, the draw is a bit higher from what i gather but still better than no controller at all!

i do not recall if i got a link from this site to the torroids i seen or not, there are however some uniquely wound torroids one such i believe was called the morbious. this one used a plastic toy doghnut and nails, the nails held the wire in place because the way the coil was wound was over the outer edge into the torroid at a angle wich ran the wire nearly straight through the center circle. there was another where they actually braided wire around the torroid. if i happen to see them again i will post links.

different windings definately can have an effect on the performance.

on a side note with this frequency talk what is it you hope or think will happen with the resonate frequencies? i forsee several options, one you find the resonate frequency to shatter the torroid. two you find one that might cause the frequency to continuously climb, three and one that i would love to see, you find the frequency that generates a ever growing voltage spike reguardless of input. i would relate that to a rogue wave in the fact that waves keep combining until they become one big wave. and sadly, as partially pointed out before i dont think your going to be able to tap a resonate frequency as electricity directly and get any benifit. i could see if you found the right frequency for a electric motor that continiously increases spede until self destruction and perhaps use that as a physical generator type output.

im currious though what do you expect or think will happen with the "right" frequency?

@ jeanna

No. watts = amps x volts = 0.137 x 1.5 = 0.2055 watts = 206 mW
In one hour the energy used will be = watts X hours = 0.205 Watt-hours = 205 mW-hr.

@xee,

Huh?

V x A = W
that is of course what I was using to get this formula calculation.

but 1.5V??

How about 367V x 0.137A = 50.28 W

I wonder how long this will run?
Would you care to use the experimental approach and time it?

@ jeanna
when you got the best results with the smaller and larger windings you had the smaller attached to the base of the transistor right?

@AK,

I will quickly answer what I think you are asking but read on.
I got higher volts when the fewer turns were at the base.


That is the interesting question.
What makes it better?
Is the higher frequency that Tesla said he needed to start with the thing I need to push up?
He was using a spark gap where we get to use a switching transistor, so we don't need to bother with all those details about the sparks and keeping things clean or at the right angle. He had a lot to overcome just to get the high frequency he was looking for.

He said he used a generator to produce the juice for the sparks which he made according a machine that Herz had used. I don't know about that machine but, I trust he did.

So, his plan was to drive the frequency really high and then put it into a transformer with  hundreds of turns of very fine wire. This put the voltage up. I can see that the frequency lowered as he got the voltage up. My guess is that he had to drive the frequency high in the first step so there was room for it to come down as he made the voltage rise.

That is where I am.

I was wondering if I could calculate this in a reproducible manner and therefore have a 'tag' for want of a better tern, to identify its usefulness. (I am trying to avoid words like potential and power here because they have already been taken.)

So you might see there is no easy answer here about which is better.

thank you,

A typical AA battert has 1000 mA-hr at 1.5 volts = 1500 mW-hr
therefore, AA battery should light fluorescent bulb for 1500/205 = 7.3 hours

Or you could just divide 1000 ma-hr by 137 ma = 7.3 hours since the voltage is always the same.

it is a bit more complicated then this.
don't forget that the voltage will drop over time.
the delivered watts is not constant during the discharge of the battery.

the battery rating is given in amp/hour and your 137 mA, if it is a measurement values, is in amp/second

probably not.

one of the function of that chip is to switch from charging the battery and lightning the leds.

whithout knowing the voltage feeding the led, it is hard to tell if it is also incorporating a dc to dc converter(jt like voltage converter) or not.
i doubt it does.
the leds are probably low voltage, low current type.

...

good questions.

what is the "right" frequency related too and how does it help you with what you are trying to achive.
what will you use the resonnance for.

personaly, the right frequency, for the jt, is the one providing me the most energy transfer with the materials i am using.

and i use resonnance to get frequencies i want/need or to filter them.

E=MC^ conversion is not what i am looking for with the jt.
i don't think 1 frequency alone can provide such conversions.

and just wild speculation.
even multiple frequencies won't do, at least not at the energies levels concentration that are normally occuring in nature.
