Thanks, I see on your first one a double frequency, there is a pulse for the "on" and one for the "off", on your second scope shot, there appears to be the same pulse frequency, but it it double-width ?



it is not double width....that is how it looks when you have it aligned perfectly......the first scope shot i showed i used becuase it put out 20 volts more then the second scope shot.

for the record

connecting your bifilar to the cell like this will DO ABSOLUTELY NOTHING.

PLEASE FEEL FREE TO TRY.

john i connceted it the way dankie swears his life on: H to F and had G as my ouput.....so my outputs were G and E just to prove dankie's wrong.....PLEASE JOHN when you get a chance try this unconnect the Gto H connection and connect H to F and use G as the output.....this is the way dankie is saying it should be connected......they cancel each other out and it is no longer an RLC circuit but an RC circuit.....the vic coil does absolutely nothing and becomes a dead weight.....for it to act as an inductor it needs a magnetic field.....please do this at some point to prove once and for all that those images are mis drawn and that the text is correct......dankie refuses to believe me and i would love to have another voice who has actually tried both ways.....the iamges you always referr to are incorrect......read, read, read.

John , Kinesis .

Plz replace your cell with an ampmeter with both my connection and your connection and compare , put it on xtra sensitive .

Also , plz put scope leads on my connection with cell as per this drawing and sweep your frequencies  . Make sure you put leads on same distance from cell , resistance must be equal on both sides.

dankie im sorry...i connected it to a laod and everything.....nothing happens.....since there is no magnetic field no current no power nothing.

seriously i am sorry it's a shame you won't let this go.

really though it does not work.

the way john wound it works FLAWLESSLY.

once again im sorry.....but that's just the way it is.

you could always purchase one from john and try it yourself.

Forgive me for asking again...

I drew a picture to help show what I am thinking...

"A" shows a pulse for each "high" and "low"
"B" shows a wide pulse for a pair of "high and low"

What I am able to see in your first scope shot is similar to "A"
What I am able to see in your second scope shot is similar to "B"

are you hitting the positive primary with variable analog pulse 1-12 volts from a regulated dc supply?   that also has a variable gate? then are you gating the negative ground with 10 khz or up matching the same width of analog pulse with matching gate?
