has anyone tried winding one of these on a coil of wire as in one of teslas patents or just on ferrite rings it might prove interesting ?

Hi Martin,
Check this page out and all the posts since then.

Stprue and I and probably others uncounted have been doing this all this week. Your suggestion is almost right on time. 

thank you,

Are you making any of these yourself?

i made similar things along time ago and they were not well recieved i am interested in the batery charging aspect but follow the whole thread and many other things but have not done much since my son died what a waiste am somewhat ok with it now i am more into wind mills for low velocity wind power but what you are doing has off grid applications and am useing them even now but that is another story for another time.
my big interest is in how energy works for power reasons and that is not what you are all doing.
i have made these about ten years ago after reading an old radio handbook for ham radio. what you are doing has applications as to tesla's car and that interests me allot as does alexander frolovs work it really is all starting to look the same but hard to put into words done right you could run a car on a single battery from new york to albany or maybe allot farther.
will post some thoughts allong the way and when want to explore something new will then build it as always.

sincerely Martin

PS i asked the question because this may have significance to the biefield brown right angle capacitance of the lifter project and some of you are always looking for something new to try it can be viewed at the jln labs page as well as the tep.
must be getting old forgot why i suggested this and had to come back.

@ resonananceman,

Congratulations on your  Bedini.



Great work   

From  what  I have been seeing  it is not  quite that simple .

I  do  agree that  changing the  base resistor  will  limit  the voltage to the base ......but that is  just the start .

I had hoped  that  I could  just  connect  my   LM coils to  higher voltage and  have higher power out .
It  is not that simple .
The  problem seems to inductance .
Our coils  are  efficient at 1.5V
At higher  voltages  they do  not have enough inductance
I have a 2.5A "leak" through my  C coil 
I added  a pot for   compensating  for the higher voltage .....adjusting that pot  does not  change the leak much . 
Tomorow  I  will  try  to make a  higher inductance  coil

Can  you take some  resistance measurements   off  the coils  in your cattle  prod?
That  would help give me an idea where to start .

thanks

Hi gary,
Im not at home just now, Im elesewhere for the weekend.
I will let you know the resistance of the prods ASAIC  (as soon as I can)

Thanks all for the congrads.

@ stprue

Before you add the other side, could you check the output voltage using a diode and capacitor and then reverse the diode and see what the voltage is. My coils all give a very high voltage with the diode in one direction and a low voltage with the diode in the other direction.

Here are the results for my 2B-10C-80P coil. I would call your coil a 2B-10C-104P coil. They should be somewhat close.

Also, was your taransistor a 2N3005 or a 2N3055?

Sure I will do this later today! I would expect the same results as you but I will check!  The transistor was a 2N3055.
