New Jewel Thief "Resonate LCR Circuit" Much less energy draw....

[sirmikey1]

Just a note, a heads up...
Davro Video, at 1:45 or so, he is creating SEC receivers which are also "repeaters", have their own trigger coils.  I think this is a real biggie, unlimited current and current magnification.

I noticed that the trigger coil version of this circuit includes an optional resistor at the base of the NPN transistor.

Has anyone got any recommendations for the value of the resistor VS the potential for voltage going through that path to the base?

How would I measure it without discontinuing the operation of the circuit.  ( having trouble determining this easily )

Jadaro,

  You can use a variable 4meg pot or a string of resistors that you can jump around, to find highest voltage/resonance.  Gets hot if you dont. 

  Works well for KV with some coils, and not so well with others.  I added one NPN and get 1350v.   Might try Lidmotor's MPSA06 darlington NPN if needed.

Regards,
Mikey

The circuit itself is a sort of Darlington setup.

I am referring to the placing a resistor at the base of the NPN transistor.

I believe that the CE resistance of the PNP transistor would be around 1 or 2k when the base is about 3M.  This essentially cuts the path current down significantly through there already going to the base of the NPN.

The only wastes that I notice are in the current drains from base to emitter on either.

@ jonnydavro

Thanks for A your results. It is amazing that you can light the LEDs wirelessly so far away from the transmitter.

A new drawing is attached. I would like to replicate some of your experiments, but I do not have any large space to work in and I am afraid the high voltage fields may damage things like the TV and computer. Have you had any problems of that sort?

Hi Guys

New to this forum and just attempting some of the new JT variants.  Has anyone had success with a simplified 'SEC' type version such as was posted by Xee (but JohnnyDav design) however with really low voltage/amp draw rather than 5 volt input?
I'm looking for something that will run on the smell of an ozone vapor :-)

Thanks for your help
