Claimed OU circuit of Rosemary Ainslie

Harvey:

It's Boris the Spider from the Gulag in Siberia.

Как Ð'аши дела?

It's not really a problem if the grounds are all common as .99 plucked from the manual.  You have four channels, you are in oscilloscope heaven.  Let's use the battery ground as the channel ground, shall we?  Connect Channel 1 across the main load shunt resistor.  Connect Channel 2 to the battery supply voltage near the positive shunt resistor.  Connect Channel 3 to the other side of the positive shunt resistor.  You have all the information that you need to crunch your currents, plus you have a bonus channel!

Connect the bonus channel to check what happens to the potential difference between the two grounds of your two quasi-isolated nodes, or whatever else you want to do.  Perhaps that tempting gate signal?

Suppose Aaron exports that data and you whip up the Excel spreadsheet to plot it.  It would be really cool if both files were hosted on the same freebie hosting web site.

P.S.:  .99:  Can you run an FFT on some of the signals in PSpice?  it woudl be fun, and educational for some of the audience.  We have the technology, we can transform the description of time-based signals into frequency-based signals and go back and forth through these two dimensions or domains and actually see the harmonics!!!

Я очень, очень усÑ,ал прямо сейчас.

I had already provided Aaron with this arrangement yesterday in a PM. I suggested he use the channel 3 & 4 differential setting to provide a single trace of the difference. Good to see you reading there and offering the help

TK update
TinselKoil 10c: Lightning

Awesome. Even if I do say so myself.
I have seen SS Tesla coils with higher voltage, of course, but this is the first small one I've seen with this kind of power transfer capability. I must have done something right.

TinselKoil 11c: Baby Poppa Mosfet

More awesome lightning, clearly at the limit of the device. I hope.
Demonstration terminated in fine fashion: overheat under power, a blown seven-dollar mosfet, probable cascading failures in the x-bridge.
Diagnosis and repair will take an hour or so, and I think I've used the last of the IRFP252 power mosfets and will have to load a set of IRFP264s

I was going to suggest the differential measurement. Especially handy when 4 channels are available. Glad we worked out the probe grounding issue, that could have been detrimental to the health of the scope.

Poynt - please help me out here.  What is the heat of the white hot centre in TK's plasma number?  I've looked this up and can only find the heat as it relates to star structures? 

And what does classical physics say is this plasma?  If they're ions then from where? I'm not talking about plasmas generally - just these sparks.  I'm trying, belatedely to get my head around this 'electric fire' thing.  If you know a link for the terminally dull-witted it would help.

I answered MH here and lost my post.  I'm having difficulty reading the instructions because they're in German. How do I get this changed to English - or is that not an option?
