Back to Basics

@Yucca,
Remove the 50ohm and fire a 2nd pulse at a certain delay much shorter than your freq obviously.
Yes thats right! No resistance. You will see very little amperage due to cancellation before conduction. This has been done by a number of us here. Why you can even use a short, straight piece of wire! This creates the shock wave. The pulsing protocol is faster than the copper conduction or current dispersion into the conductor. Houston, we have wave! On this USB based system it crashes the controller app on the pc. Going to wireless USB hub to allevitate this.
That is why the JDO controller and SSR boards have been so important, although not neccesary if you have the right, expensive equipment.

Can anyone beat a Full house?! There are still more cards in the deck to be dealt.

Thanks for the info GK, appreciate it!

I will try and make a second delayed pulse derived from the signal of the first. Then I can change the freq and change the delay seperately.

Unbelievable that your'e producing enough hash to crash your USB interface from these VERY short pulses! Sounds like you have excess energy radiating ready to be mopped up somehow. The only time I've seen my usb keyboard and mouse go down was with a 10W spark fired aircoil.

I think I can cover freq generation and delay stage, are there any particular SSR switches you can recommend for the job?

@Yucca,
Depending on your setup, check the current draw for low milliamps. If you are using a digimeter and see it display 1 or -1 then things have started to build. Just let it go to see if you get a scope full of hash or Mghz signal, or your Pc hangs.
Try this also: If your signal line is not shielded then take about 6" 26awg and wrap 20 twenty turns(arbitrary) around the clock/pulse signal line and lay a portion of it parallel to the same line. We can guarantee coupling in both directions. Put a scope on the clock line and watch it. If you have an analog scope or isolated probes then good. You'll last a little while longer. 8-) You should see the signal become unclean at the event. Might be too fast for your scope. The clock line antenna can act as an injected drift or signal build. This could or could not serve as a firewall. This could depend on signal eclipsing, total mass, diameter of all the wiring. The results can vary. I should state this. We are using submarines to explore space! Hope this makes sense.
Also, I have no Iron in the build but the 15" loop is quite the transmitter. My thinking is you can use a smaller circumference with iron and larger circumference with no iron.
I know my builds get complicated and I need to simplify a little. Without correct shielding or test approaches then the event can happen at any time in any capable build. The results can be short term most of the time.
In case it hasn't become aware to anyone. I have been chasing the event continuously over time. What I realize is this event whether short or long term is inescapable. Most of my builds have gotten this thing. My thinking is this is the thing to capture. I just wanted to see how many different situations I could setup to hammer on this issue. I saw that the event was and maybe is illusive to some. Alot of our coils in inventory have potential. If we had the tools for that side of the energy fence we could make better progress. Gotta knock the mystery out of this.

Back to the stun gun topic:
The stungun produces this effect though it is quite long and wild. My thinking here is by sending this shockwave through long circular inductors to charge caps we can effectively create an aperture for an energy sucking attenna. This has been mentioned by others before.

If you get a headache then stop. The negative effects can last for months.

@GK, Thanks for the info. Submarine hulls make the most robust spacecraft. For now I will hold off on stungun, for fear of frying my bench.

Tonight I just played with Ottos wire and coil test. I had quite interesting results:

12V auto bulb, switching 6V using IRF730.

CH1 1 is output from FET driver.

CH2 is the FET drain where the coil and the wire meet.

CH2 was very chaotic with runs of order in it. To try and see order I set trigger to CH2 and turned it up to show only the highest magnitude spikes, then I tweaked duration and period until I was able to increase trigger more, this way I found optimum.

As I tweaked pulse duration and period I was able to observe the spike grow until I saw max when the spike was half way between gate pulses. It was very twitchy to find optimum pulling the period just slightly dropped the amplitude lots.

Without tweaking trigger I would not have been able to tune because as I say the spike levels and makeup fluctuate wildly. Even when tuned for max if you just trigger off the gate signal the drain signal is crazy.

Around the optimum point my PSU digimeters went nuts and a small USB player a couple of meters away intermitently lost USB interface. At optimum the bulb increased slightly in brightness. The FET was barely warm. I'll be playing more with this.
