@ All:

I am still working on the diagrams topic but, i want to call your attention to a post made by Spark's that I think we need to revisit.  If you go to that topic and look it is one of the last posts I put up.  He speaks about high voltage and amps, and lack of amps, and how, if we get the volts up high enough and dump into a cap, the amps will be there as well.  I know I missed it the first time around and it is very good reading.  I don't normally copy posts for that topic but in this case, I made an exception.

i have sayed the same thing a while back, remember the time frame posts.
and if you look at IST signature, you get it in each one of the posts he make...

NOP:

I don't doubt that.  Just remember, I am only up to page 220 on my other topic, it is very slow going because I have to convert every posted photo (for some unknown reason) and then upload it.  So, if you said it prior to page 220 then I am sorry I missed it.  If you said it after page 220, then I am sorry I didn't see it when you posted it.  I was just trying to give a shot in the arm to some of the folks that may be thinking volts are nothing.  I already know you and IST don't think that way, as well as many others on here.  I hope you understand.  Thanks.

Ah, echo?

and that echo, is that like a bunch of pulses
...

btw, how many turns does the JT base for that have again, and
how many the pickup?

@Koen,

I am not going to try to answer that, myself.

I do want to say again that this is a cathode ray version of the digital therefore squared off picture I am getting from almost all of my new scope shots.

Last night, for instance, I saw six in a bunch. the tops followed a sine wave shape, then they stopped for a while and there was nothing. Then they repeated.

Most of mine are so complex I cannot identify the beginning of a repeat. But the basic shape and the repeating of the basic shape into a pattern is what I am seeing. Each coil , of course, has its own fingerprint, so to speak.

The example I just gave was for the coil I described to MK1 earlier today. It has only 6 winds and the primary is split. This split is the same type of primary that IST uses in the one he
shared today. This shape only shows up when I set the scope to a certain frequency too. - It is there, but hard to recognize.

Echo?
I think no one really can say for sure what they are. Maybe the word kick is a better word than echo? I dunno.

My efforts will be to even these forms out over the total wave. I think it is probably not good for anything to have such raw spikes going through it. (Maybe that is just the human talking but they hurt.)

I do have one that appears to be almost perfectly even. I am looking for what makes this even-ness happen.

Oh so many experiments to do....

thank you,

@Pirate88179
i understand. 

[innovation_station]

just cuz i can be an ass sometimes lol

just 4 u MR MAGS

LOL




IST!

hers a pic of youtube on pause..... 

@ mr mags ... i dont care if you invented the scope .... lol  .....  per haps your 30 years of training hinders you ..... 

want more pics ....  lol   


come on  why dont you BUILD IT MR MAGGS 

LOL

so just HOW MANY VOLTS ARE THOSE SPIKES.....   LOL  LOL

ALL IS DONE ON THE 10X PROBE ...     VOLTS PER IN MY LAST PIC ARE .1V/DIV

LOL
