Joule Thief

[jeanna]

Who Told you that ? Your wrong . @ volts will knock you on your ass at 650 amps with Moist hands . I know i felt it . Amperage is the killer here not voltage ..

The reason people die from this powerful electricity is because it confuses the heart signal.

If you touch one of these high (volts or high amps) supercaps with both hands the powerful pulse can go across your heart and confuse the signal. If you keep one hand behind your back so you are not tempted to use it, you will not die.

You could be burned, however.
If the thing when it shorts can melt a thick wire, it could burn your fingers as they touch the leads and short them across your skin.

Here is an amazing story from my childhood:

My father was a doctor who spent years reconstructing a man's arm after a high tension accident.
The man who knew what he was doing because he worked on those wires, slipped and instinctively grabbed a wire. 
The muscles in his arm were activated, because it is electrical charge in the body that normally activates the muscles, and his hand grabbed the wire and would not let go until the entire hand was charred and some fingers were gone ...(I was little and don't know all the details)

My father eventually managed to give the man a human claw by lengthening tendons and borrowing and connecting muscles from elsewhere. I remember hearing that the man had to use a muscle that normally does one thing to do something else. His brain had to re-learn this.

As you can guess I was fascinated by this.

So, be careful.

After writing this  it occured to me that I could   keep  the battery  from having to  both charge and discharge  each cycle by placing a LARGE  cap across the battery .
In theory  I should be able to  remove the battery at any time .......but  I can
;t
With the cap across the battery  I can  run the JT several times faster .
I think what is limiting me now is the power of each pulse .
I think  I am  doing this the  hard way .
If I was driving    a  large load ........like  a few dozen  LEDs  I would have large pulses to  run through my  coils .
I am using  the coils  themselves as my load right now .
It might actually be easier to get it to charge  while  running a real load .

Gary,

Put a load on that JT and you will have it. I have found that when I have a heavy load on the circuit is when I get the best charging.

And the biggest voltage spikes I checked this with my scope as well. I can tune the JT with a pot and get it charging every time now.

Oh, thank you, A;trez.
I appreciate that.
What is an LHR meter?

I am thinking about starting a new joule thief thread specifically on using the joule thief to produce AC then continue to use it as AC.

Most of the wonderful folks here are looking in other directions and I would like to concentrate on AC. Maybe others who also want to look at this as a producer of AC will join.

It does not mean I will leave this thread anymore than I left either localjoe's or Bill's earth battery threads, just a better concentration.

Someone a hundred posts ago said we just didn't know how ac circuits work. I believe this is true. I didn't make note of the link that person provided, so I will go back to studying what the master... Tesla had to say.

For today or maybe this week:

My plan is to wind some secondaries in a slightly  different way. I am thinking of winding one in the way MK1 does, but with a smaller number of turns and adding another one made in a similar way to the same toroid.

I am really not happy with the high flux toroids I bought and although they have more room, they may just take so much wire for primary turns there is again no more room left for a big secondary to produce over 270 volts.

The sun is blazing again today. I need to water my plants 4 or 5 times a day, so I better go do that now!

I am sorry LCR meter I was half asleep when I wrote that lol. I would love to have a thread dedicated to AC I will post for sure. That is a great idea!

@all

Today I got a copy of Free Energy Generation 20 Bedini-Bearden years and I must say its a great book. Off topic I know just wanted to post that bit of info

-Altrez

Yes it is . i have my copy all nice and shiny too . you learn a lot in it . ! 50 bucks is hight but it was worth it . I proceeded to make a self runner with that info .

@ Pirate . Dr Stiffler Is to scientific plus this is not a super cap this is the newest technology Ultra BOOSTCAP . Different makup altogether than a super cap But you know about that guy you can't argue with him cause he will go away and pout and then come back and make a long speech about how uneducated and stupid we are so .. As far as his Sec its an unshielded Hf Transmitter and I am Building one cause i like unshielded Hv RF  . Same stuff Cb's put out on the antenna . you can light  a hundred tube florescents with only one end  on a CB or  HAM  antenna My goal there is to run it off a Jt 1 volter instead of 12 volts and Put a Dish to beam the Rf  o a remote location , 12 feet away . . . 
And as far as the Maxwell Ultracaps being Different in that they are more powerfull and are considered Lithium Battery Replacments . You can hook up as many as you like in series or parallel . Here a Quote from Maxwell :Maxwell Technologies, Inc.’s BOOSTCAP® ultracapacitors in series or parallel.1 They are no different than the principles one would use to interconnect any high-current energy storage cell, and should be familiar to anyone who has interconnected batteries.


SO there you go . One More Think . Thes caps can be OVERCHARGED just like any other cap . A cap will not stop at its rated Voltage . For instance if we have a Jt put out 20 volts dc we can fill a 100 volt cap up . They don't just stop at the input voltage and yes adding a diode in these will slow down the charge rate and you will notice they don't charge up like they do without a diode .   But As Jim said  to Pirate its agood idea to keep this in the house and put a diode on it to keep the Eb current low rather than at 650 amps or whatever.

Gadget

Wow that shows how much I know. I was sure that a cap would not charge higher then its input voltage? So you are saying that any cap will keep charging from a low volt source until its full?

So I can take my 1.2 volt battery and charge a 330v cap? I have never got that to work?


Edit:

Well if I can take a 1.2volt JT and charge lets say that Maxwell cap to 2.7 and its full 650F is that not OU? I just tried on a fugi cap and it stops at what the source voltage is.  I must be doing something wrong?
