Giantkiller moves forward into Full Heterodyning.

[Feynman]

Hey guys, 

I got back from my trip early AM, and I noticed today Jon has started his 3D heterodyning graph (two frequencies).

I have no readings. That is just a schematic from the web. What interested me was the lack of internal spark gap.

I understand your excitement! If you can get three of such stun guns running in cycling manner, driven by a single 555 as Spherics suggested, you'll be a winner! Just don't vaporize your lab - 30kV at 8 amp is too much  in my opinion. You'll need to lower pulsing frequency drastically. Probably you'll also get objects flying around. If you ever get the response drawing of this stun gun discharge - in air or in coils please post it here.

If I put a reed switch across the terminals of 1 switch I could trigger the cycle with a magnet swipe!
I also am going to hook all 3 to 1 - 9v battery.

My dogs are scared to death. I got to put them somewhere else while testing.

@GK - the choke i made was .33 mig welding wire inside a cocktail straw with wax ,to adjust it. wraped 3/4 inch 3 or 4 layers radio shak 33Ã,  wire (red stuff). then the straw was cut off with a little to mount it with. the one that was real bad was the bifiller so the ends went fron top to bottom and the second one the same way to connect to the caps. when I look back I wished I'd isolated the bifillers (paralle ) in the same coil , this would let the flow go both ways and cancel the mag fields( not twisted , just warped oppisit directions real tight.  this is the idea that SM seem to relate to but in the way I interped it he may have had one balling wire and the wire warped the same way with a gap at the ends of the bail wire

Thought I'd go back in time and resurrect an old test:
I have a stun gun feeding a diode 1, cap 1, inductor primary loop to cap 2, diode 2, sparkgap, back to gun. The catch is one side is open,  the extended spark gap. The current trap is set.  I pull the trigger and fill up the caps. I released the trigger and waited 1 minute. The scope shot shows the spikes that appeared to show the ringing. The ringing lasted 3 minutes at an average of 49v pk-pk and a frequency of 2hz. Thats right 2 per second. The stun gun has 2 nine volts in parallel.

I couldn't pull the trigger anymore. It took down the router, froze the pc-s, scared the dogs(they'll probably break bond with me), and upset my wife's dog, who jumped in the shower with her.
You too can enjoy youself with miniture weapons of mass destruction. Maybe I should switch to FETs, eh? I could control the frequency better.

Forget the pix. this site is screwed.
