@ crowclaw

Thanks. Are these the voltages across the coils? Your scope is great.

Here is another idea for those who want to experiment with. My  JT biffilar wound toroid has an equal number of primary and secondary turns. In this case 22. The collector has a diode output... anode to collector. Now take another diode from the primary feedback winding, cathode connection but this time you are capturing the negative pulses. You now  not only have positive spikes but also nice negative ones!! Your output is between the anode of one diode and the cathode of the other almost doubling the output of the circuit!! The output of this configuration can be seen in my attached scope shot. The unloaded output measured between the positive and negative peeks is well over 120v ( X10 probes) Remember this is a floating output only so don't common  ground the outputs to the JT common ground. Usual warning applies when working with high voltages... please be careful.

Yes, what kind of scope output to PC like this?

here i thought i was the only NUTZ one lol ... 


hehe

ok 

like to report   the SMITTERMITTE LIGHTS!  WORK GREAT!

burn em out over night !


some one need high teck nano quartz coated ORGANIC pest control GROTH ENHANCEMENT devices ??


i have a few diffrent ones to choose from ... 

: )

W

here is a good question for you to ask   

because im shooting saclar  vortexes down ward   from above   will that add to the BIG WHEELS IN THE BACK YARD AND REINFORCE IT ? 

hummm

im gonna call the last unit GROW RING SKYL;AR THINGIES! ...

It's a module which works through a PC  and combines the functions of a scope/spectrum analyser/ multimeter etc.
