Just explained the setup to a friend and he said that it was not working like I think? He is an EE and was in the Air Force for 30 years. He basically said the JT is simply a transformer and that a DC - DC converter is far more efficient then a JT when converting to DC?

Not sure about all that but I do trust him. He also said that I was not really charging the battery's at all? And that the voltage was empty?

Can anyone explain that?

Thanks!

sounds like a knee jerk reaction. you can test the 'empty' voltage and see how 'empty' it is.

What is empty voltage ?

It  looks to me like your friend is very well educated .
It looks to me like your  friend   learned  all he knows  without questioning it much.
To me  it is clear that the  curriculum  of even our  best  collages  has been  tweaked by people  that  have a vested interest in  keeping people   hooked  on  their  power .
The  "quirks " that we could  use to get OU  are   simply not   discussed in  any detail .....they are not studied .
How to get around these quirks is  taught in great detail

It is  good to trust  your friend ...........but just because he has a good education   does not mean he has the real facts .

Trust what is on your workbench .
If you can power  something  with   a battery you recharge  with  your system  ........who cares if the  voltage is " empty "   

Keep  up  the good work

A JT is just an easy to build DC-DC converter that puts out high frequency pulses at high voltage. Battery voltage is not a good indicator of energy stored in battery. You should talk to your friend more.

That is how I set it up Monday and yes it works fine Great Job!!! Do you mind if I add that to my design?

Thanks!

Please do!

Just a question , How long dose a uncharged battery last , yes i know its still undetermined , lol , the battery may even get better with time , well you tell us !

We may not be making OU but we use every little bit of juice , from a minimal 1.5 God those are good batteries , or less Ha HA .We are finding new ways of using it every day , a AA battery can easily be replaced by many little energy source solar, wind , home made battery , air system , you name it !

This is not just about excess energy but the ability to use new means of power !

@all

A little circuit i just found , i did post it a while back , it has nothink to do with the tpu but its a more in the basic jt mod kind of thing , but now its used for making a blinker but if it is set in resonance mode may be the way to go .

I also have a really interesting info , i was looking for a way to fine tune the mk type 4x4 , so i made a dummy toroid . A second toroid , but connected first , so battery + 2 coil on one toroid reverse polarity reverse wind , not sure if the reverse wind make a big difference , connected to the mk 4x4 coil in series so the dummy is first then the regular jt , ok so far i found a way to either bring down the voltage from the mk secondary in a big way or keep ot about the same , i am sure there there is more to learn about this , but more interesting is that a secondary can also be made around the dummy , the exciting news is that this load dose not affect the mk secondary voltage so i can charge caps load without lowering the voltage from the secondary on the mk on the 4x4 if you load a coil all the coil will still have the same load voltage , so you need to compensate but on the dummy its kinda nice more power to send back to battery , or cap humm.
