i made me a jt train one jt run a jt running a jt..
i know you guys done this before.. but i wanted to try it..

Great work


I might have missed something  but I do not remember anyone doing more than 2 JTs in a row.

I am courious about  if  this  could tie in with what I am playing with at the momright ent.
Single wire connections.

Right now I have a JT with each leg of the secondary connected to  a good sized bedini type bifilar coil.  ( 2 bedini type coils )
I connected the ends of one  of the windings together   and  connected one leg of the JT secondary to each of these  .
The  idea is to make  one winding of the bifilar  coil act like a capacitor.
The theory is that  a capacitors charge " shakes " the  area surounding the cap but this shaking is not  part of " normal " teachings.
I am  harvesting this vibration .......
I think.
OK .........getting back to the circuit.........each  wire of the 2 bedini  coil secondarys are connected to diode bridges..........4 ends  so 2 bridges. 
The  output of both bridges is connected to a couple of  supercaps in series........ 1 LED is  connected across the  supercaps........ the circuit is  running  holding a steady 2.73V

I hope I have explained  this clear enough.......
I was wondering  if  your JT string could be set up with one wire between them ..........I am guessing it would take  bigger coils.

Here is a quick drawing of my circuit.
sense  each of the wires of the extra coils secondaries are connected to the bridges it looks like circuit is  pretty normal........but each of the wires can be used alone. .....each additional wire connected to the bridges  adds to the power.

The schematic shows one leg of each coil going to each bridge.........connecting  both legs of one coil to one bridge  lowers the voltage slightly....... .02V

Hi Gary, why are the two primary windings of each output coils shorted out!! I think you need to amend your drawing. Ive also notice your LED is wrongly shown... the anode connect to the +ve point, not the cathode!! The last point depending on how much voltage and current is available you could well damaged your LED without a series resistor to limit the current... remember you no longer have spikes, just smooth DC voltage!! Kind Regards. Merv

Thanks for pointing out I had the diode backwards.
As for what you call the shorted windings........that was the point of the whole drawing.

I tried to explain what I was doing on reply #14258
I did the schematic  just to make sure that things were clear.

Vaporizer
Here is the schematic  of the circuit  you were interested in as close as I can remember.

I do not remember exactly how many of the  coils went to each light........so I drew it  with just one light.

The flyback and feedback still apply
All the flyback is connected in series with the load.
3 of the secondarys  are connected for feedback.......one for flyback.
All feedback is connected  in parallel with the Jesus charger...... I am not sure that the cap  across the bridge in the Jesus charger is required ........but it is what I used at the time.

A high impedance load is required for this circuit to work properly.
