NEW MOVIE Slim Version 5 turn 16 layer http://www.youtube.com/watch?v=U9BMTAlL0dU

Lighting leds on the satellite coil , and the 2 volt bulb on the secondary .

8 turn secondary about 10 v rectified dc .

The picture is from an 6 volts bulb .

i bet a spark gap will work well for a ark resistor !   

i designed the spark ark  quartz light ...  /  regulator   

and i also pulled apart a heater for the reostat !

it will not work on low volt ....   bet it works awesome for my high volt ...

since i cleaned the termanals  it is running as a usual bedini   chargeing no problem but 10 times slower than the high resistance mod / spark gap ..

: )

im chargeing at 13.5 there bouts volts! 

ist


im useing a 35vdc 17 000 uf cap

its probally safest to run it the way i have it ...  as who knows if a battery will explode or not ...   

atleast how it is it is regulated and chargeing as a battery should charge !

Here's another JTC with an independent oscillation tank circuit.  Seems you can control the oscillations with the capacitance and the inductance.  Unfortunately, the inductances need to be close to one another ( measures not proximity ).

Still working towards a single transistor, single inductor design.  Trying to reduce the number of components in the boost.

Blue is an either / or path for the capacitor.

I am pretty sure your inductors are coupling. To check, try reversing one of them. If they are not coupled then that should not matter. If they are, you should be able to reduce the inductance of the upper inductor by moving it physically closer to the lower inductor.

I tired to reverse the inductor, I also turned it 90 degrees, there was no operational differences, it seems to be decoupled.
