I'm impressed. Do you sell them online? 



I've switched out the transformer in Nelsons circuit and I have my two ribbon TBP stacked on top of each other in parallel instead. Yellow trace is on one coil & gnd and blue on internal tap point. I only get the ring if I use two coils.

No. Just doing them for the guy that rents them.

Im not sure what you are saying about the coils

Sorry Mags, that was a bit vague. 2TBP stacked on top of each other with ferrite through the centre of them.

Added a third coil that was wound from a Cat5 cable so a TBF wound in helix form. Wired same a ch2.

One word sums it up......damn.....

He hits you with a wet phone book....in the face.....with the mother of all nuggets.....find it!


Sweet video TK from the guy who dislikes scopes and proper measurement.....

Connect that to the nano pulser? To the neon terminals? Test that for output?

The toroid transformer that is in Nelson's circuit...

I found something interesting one might want to consider about it.

Connected as Nelson shows in bucking style configuration, if pulsed with DC,
there's an interesting back swing not obvious just looking at a voltage or current
signal, but when you turn on the math trace and calculate watts, you can clearly
see the reverse power spike.

Is that just the toroid your pulsing?

Yeap.  When it's wired as bucking you can see the current and voltage doesn't respond
exactly the same, hence there is a power spike created opposite to the direction of the
input flow.  Back EMF?   Seems more than that.  It's actual energy per time, power.

Doing some fiddling with the turns ratio you can change the characteristics of the spike.

I couldn't for the life of me figure out how Nelson's training circuit could generate spikes,
but I see it now.

sok more winding to do. :)

Didn't I try that already? Maybe I forgot to post the picture.

SO I've been playing with Nelson's pulser and I hooked up a TBP transformer of one pulsing coil a pick up either side and a ferrite through the middle. The neon glows incredibly brightly and flickers purple like plasma. Anyone else seen that? What is it? Mags I tried hooking up to the output of transformer but get better results hooking it up directly. :)

Hey Jim.
Would be easier to see what you are telling.  ;)

Yeah I know but I'd have to clean up my bench :)  ok uploading now.

I've since added a 3rd TBP coil to this transformer. https://www.youtube.com/watch?v=erReC82Y308
