@all

I am ashamed now and I want to apologize for my second failure. It seems that the whole thing was a lose connection. I will post no more.
I will not resist a third failure.

You are clearly  confused  about a few things here .

Edison  tried  over 2000  different  filaments  before  he tried tungsten .
Some  people  would say that he failed 2000 times before  he succeeded .
I do not see it that way .
Edison  would  not  have  succeeded   if  he had  given up  before  he tried tungsten .
Edison  didn't fail at all  because he did not  give up .
No one  fails  until they  give up .
No on is a failure until they  believe that they are less of a person  because something they tried did not work out .

If you need to a break  or need to move on that is fine
It is  OK  if your  circuit is not   perfect.

It  worked great for me  for  hours yesterday .....then something  changed   and  I could not  get it  charging again .
I so NOT see that as a failure .
There is  just  stuff going  on with your circuit  than  we yet  understand .
In any case ......... you have did  a great job.
Your circuit  has  lots of possibilitys  even if it never makes  it to   a full blown  self charger.

Wireless transmission of power with a properly tuned toroid is it possible? I have increased my charging voltage to 2.1 volts by some means and I am not sure exactly why but if I take a pickup coil and tune it like an antenna It will spike the voltage of any JT I have in the cluster?

P.S still on the same set of battery's.

any jt should do, even the basic ones.

my experience with batteries with voltage without amps is comming from that "charger".
it does also recharge rechargeable batteries, but it take days to fully charge them.
the volts is the first thing to reach 1.2 volts, usually within a few hours.
once the max voltage of the battery is reached, charging it in a conventionnal charger, if you are in a hurry, will work.

you can extend the battery's life this way, but there are limits.
the charges the battery will be able to hold, if it worked, will not be as if the batttery was new.

I agree that  charging  with   pulsing DC  is  different than  with aconventional  charger

I am not sure that it is  slower .
I keep my  power  low  when I recharge ........  I want to KNOW that I am not boiling off electrolyte .  I want to be able tp  leave it alone for a while and  now that it is not  doing  any damage  ..........

I agree that  there is a limit to   the life of  batterys .............but  I am  finding that with lead acid at least  the life can be many times what most people  get out of them .

Hello Gary, put an add in a paper asking people to let you have their preloved computer for $10 bucks, offer to pick it up for free.
Youll be surprised how many people ring up to get rid of their "junk".


I just came back from the junk man, scorred myself a small UPS and a power supply with a see through plastic fan, picked up a 125Gig HD, all for $5.00.

Another way to get hold of redundant PCs is to do a "flyer drop" in a well off subburb, tell em you refurbish computers and need parts from others to rebuild em.

Once word gets around that you are a computer man, people will actually give you their old PCs rather than turf them out.

Go and visit your local council tip, see the head honcho, tel him you need a secondhand PC, and offer a few bucks to get one.

I just walked into the local scrap fella and said, hi fellas, I looking for a computer, have you got any? Back came the answer, shure, go down this side of the building, take you pick, there was about 50 in the pile, all sizes and types.

hope this helps

Thanks for the advice

This is a must see !!

This is incredible, I will preform this experiment to see what type of voltage and current are being used and produced after my vacation 2 weeks man that's going to be a lot of reading!

This looks like what tesla was talking about with some of his coils!

Good find MK1
