@ Hazens1:

Very nice work there.  That is a lot of light!





I have to read the Tesla links.  This is great.

Nop disregard that one , if its not for you , but the other ones are still worth reading.

too later, i red the 3 of them.
that is why i said, one of them is not usefull.

why do you say ancients great philosophers knew better ?
modern sciences are based on their works, and theirs works were based on what they observed in nature.
atoms, when first said existed, was the smallest possible thing in the universe, but today we know better.

Tesla was a genie, no daought about that.
but he was not playing with magic things, unlike what most peoples here seem to think.
he was able to think of the outcome of his experiments even before doing them.
the reason he still was doing them was to prove it to himself.
but to do that, you must understand with what you are playing with, you must know all or at least most of the rules.


you don't trust the news but you trust unknown men/women who wrote unverifiable things just because he/she wrote it in an occult/obscure way.  
nature does not work on believes, it work on rules.
sometime there are special cases, sometime there are none, but the rules will always be there.

might be better to take this private if we are to argue about what is truth.



about the circuit here:
http://www.overunity.com/index.php?topic=6123.msg174236#msg174236

the 1k resistor is in the way.
it is protecting the transistor from heavy currents, but it is also limiting the inrush currents effect.



@all
in series the total resistance limit the currents passing in each led, no matter if your supply can provide you more.
in parallel you are not limiting the currents passing in the leds.

but, in both cases, be carefull that the voltage is not way higher then what the leds can tolerate.

If my theory of base resistance vs frequency is correct, then reducing the number of turns on the base coil should allow the current in the collector coil to get to a larger level before the transistor is turned off. This is because the amount of current induced in the base coil is a function of the number of turns - more turns equals more current, less turns equals less current. Since the voltage produced across the collector coil is a function of the current flowing through it when the transistor is turned off, then allowing the current to increase to a larger level before turning the transistor off should create a larger voltage across the collector coil when the magnetic field collapses. This in turn should produce more power in the pickup coil. Therefore, by changing the number of turns on your base coil from 7 to 2 you should produce more output power from the pickup coil in your 7-7-70-70 circuit. This might be helpful if you try to light a fluorescent tube.

NOTE - you do not have to remove your 7 turn base coil, just add a 2 turn coil and use that for the base coil.


previously posted theory re-posted so you know what I am talking about:


THEORY OF JOULE THIEF FREQUENCY VS BASE RESISTOR VALUE

Increasing the base resistor value reduces the base current. This current flows through the base coil. When the resistor value is high the current is very small. When the base resistor value is low the base current is larger.

When the transistor turns on the current increases slowly in the collector coil (as a result of the inductance of the coil). The changing current in the collector coil induces a current in the base coil that opposes the base current that is already flowing there due to the base resistor. The larger the current change in the collector coil is, the larger the opposing induced current in the base coil will be.

When the transistor turns on the collector coil current builds up very slowly. But at some point the increasing current in the collector coil will be large enough that the opposing induced current in the base  coil will be large enough to cancel the current due to the base resistor and then the transistor will turn off. If the base resistor value is small, then the base current will be large and it will take longer for the opposing base coil current to increases to a large enough value to be big enough to cancel the base current flowing due to the resistor. Thus it takes longer for the transistor to be turned back off when the base current is large (small base resistor value) than when the base current is small (large base resistor value).

The frequency is just how often the transistor is turned on and off. With a small base resistor value (large base current) this happens less often during each second due to the longer time it takes the transistor to be turned back off. Thus increasing base resistor value increases frequency and decreasing base resistor value decreases frequency.

So frequency depends on the base resistor value and the collector coil inductance.

Nature is magic.Like i said truth is inside the man, your truth is not better then mine or mine better then yours.
Modern man always assume what is and what can be, until proven wrong .

But the occult doesn't mean magic in any way , it only means hidden, and believe me there are some crazy people
ruling over us , with some really crazy values and practices , how can you see a prison without bars, prison for the mind.

Human history as tough is only partial truth.

We can't even get how important plato and his revelation are yet, even with this modern technology we have now.

And my views on relevance of the occult tesla book, is still undetermined , since i did not even have time to read the said book. That being said , i can't say if anything is more truthful then anything else. I can said that if a man can think its a mater of time before he can realize his tough, aren't we living in a star trek technology world.

My point is unexplained can be conceived as magic , and man has a long history of taking advantage of others less knowledgeable man.

My message is to keep a open mind , and a pure heart !

I know many time , i said things that seems crazy , and go overboard on ideological  views , because i feel there is no time have a closed mind.

I would love it if everyone could know the real nature of man and gods , anything you see on this earth are based on the flower of life , and i believe that man is here to learn to love ( having no ego to cloud there judgment or actions) only then dose the real truth will be reveled step by step. But every soul will see it in a way that is best for them.

In the end all i am saying we no longer have the luxury to think that we know more or have the most evolved technology
then Pre-Diluvian Civilizations , we are only starting to see what the oldest human text mean. And lest face it most technologies we use everyday was invented to make war , from there conception to execution , in a war there are many fronts , there is even a war being fought in every one mind , these days internet is under assault and its mater of time before they stop it.

I would really like to show you stuff , that will make think and maybe you will see what i mean .But  I your are willing .

Also free energy and perpetual is old stuff , it works  . check magnetic current page 22 for details.

But sometimes truth is so simple , the modern man likes complicating stuff , and this is a weakness.

I don't pretend knowing everything , because i know nothing more then i think i do.

But like a said no harm here or argument , i would just love people to keep a opened mind.

Any of you that read this , please find your own answer to life big questions.

The real genius of Tesla was his intentions , he never made anything to make money of the back of others , he did all those great things for us free of charge.

This is on of the reason he was hidden , from the common man. And said to be crazy.

Yes i know i am crazy , but that is not all i am .
