Joule Thief

[resonanceman]

Thank you @resonanceman !
How it has been going?

I will build a new toroid coil and start from step one.

Jesus

Jesus I am glad that you are   giving it another try .

I think I am going to  spend most of my free time today making a new coil


I REALLY want to  finsh  my  Jesus charger .........but   when I  tried   just  putting it on  a circuit  board  it didn;t  work for me either ..........so I am  going   to  add one piece  at a time to the  board .

Right now ....I am waiting on my charger  JT
I need to verify that I can  get   a full charge from the same  exact setup  by only  adjusting the  pulse  ( keeping it   around 1 flash per second )

When I am expermenting   I  hook  everything together with alligator  clip leads .........I will need  some of them  when  I  work on my Jesus charger .
Right now they are all tied  up  with my self  charging JT.

What I am seeing with my self  charging  JT is that to charge the same battery  the JT must be running very slow ....... the battery being a chemical process  can not  charge and discharge at the same time ......so  you have to give it enough time to do one then the  other .
I don't  have the  equipment to find exact numbers  but   a ballpark  number is  2 flashes a second may be about max for  charging and discharging the same  battery at least that is about where it seems to  die out for me .


That seems to be the reason that  I can't  just   leave   my  charger JT alone  and  let it run ........as  it charges the   frequency  rises .......and eventually it stops  charging .

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 .

You don't need to worry about shock danger when working with low
voltages like 2 volts.  I doesn't matter how many amps you have.
You could stick your tongue across that super cap when it is fully charged
and you would just feel a tingle on your tongue.
Even 12 volts is safe to handle.  You can touch the 2 terminals of a 12 volt
battery with your fingers without feeling anything as long as your
fingers aren't wet.

As for keeping the voltage down to run a Fuji circuit I would recommend a voltage regulator circuit.
You need a 1.5 volt zener diode and a transistor to make one.
Lots of voltage regulator schematics on the internet.

Who Told you that ? Your wrong . 2 volts will knock you on your ass at 650 amps with Moist hands or just normal sweat . I know i felt it . Amperage is the killer here not voltage .. . Yea as long as you have high resistance you might not feel it with Completely dry hands but most people have a low resistance !

I will get that information for you this weekend jeanna.

Oh, thank you, A;trez.
I appreciate that.

I will also get some readings with my LHR meter for the coils.

What is an LHR meter?

Hows things going on your end?

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 would not want to see you get hurt so I think you need to do some research before you use a 650 F capacitor. If charged to 2 volts it can deliver a million amps for a millisecond if it has low internal resistance. If you do not think a million amps can do much damage in a millisecond I think you will soon be educated.

I agree totaly . . Abbarue said he would put the two volt cap in his mouth . Abbarue i guess you would like to be cremated 2 volts can kill you dude at high amperage . You will get the crap shocked out of you with a car 12 volt battery .. Just wet you hands and spark the wire on it . you will see . Do you agree Xee ?

BTW it was NOP that said 1 farad = one amp  not me . He seems to know it all about the math so i was just going by his words that 650 farads is 650 amps . I have to agree that there is more than 9 amps in that cap a lot more . It will defiantly release over 600 amps in one second if shorted or held with your lips   .
