Agentgates´s TPU setup with strange wavehill hump

[teslaalset]

@Stefan,
I've updated my data above.
Indeed looks like a capacitive effect.
I need to catch some sleep now, tomorrow I will report further

Hi all
I made a replication of first Tony's setup with tube 80mm diameter, 70mm high, wires 0.4mm and 0.8mm respectively. Driving it with a circuit shown, achieved same no-results as "teslaalset". Tried different frequencies (up to few MHz), voltages, secondary windings, primary polarizations, TPU orientation, with load and without...
I attached scope shot as well.
In some few days I will try with another, better coil driver.
Good luck

Marek FertaÅ,a

Diss is not good bebo.        Thanks for sharing.

Quick update!

This morning I tried a few more things , 15ohm limit resistor in series with power in,
still nothing but little spikes... so i zoomed in a bit and at a certain vertical resolution , suddenly i could see the massive pulse..that was much greater and wider than the previous range should have seen . I then switched to another cro and found that i couldnot see it at all. Alot  more fiddling on my part will be required to see why its not visible untill a certain point this is weird and exciting again.

mesauremant error?  I dont think so but it is the first time I have not been able to zoom in and have it make no sense.
It doesn't seem to be dc but it aslo doesn't diminish when a globe is put across it.

the ps current now remains the same and low .
@bebozek, I had the same results as you , try cahanging the volt range on the cro, zoom in an out , change triggering I dont know just keep looking.

This is getting very very interesting.I dont know WTF is happening here
still more questions than answers YAY!

IT is very important that I/we find out why I had so much difficulty seeing this pulse.

One thing I did find in the 10 minutes this morning  is that the rise time of the switch pulse is important

my main cro is a 400 mhz analouge tektroniks . I have 3 others, and many probes

More soon

@ Tony, thanks for you patience, though kicking and screaming we will get there!

Edit .. Whatever it is It is NOT frequency dependant.. Just like Tony said so dont bother changing frequency to see it ..
@ Stephan it is not  what I wanted to believe either

That walk with nature is a vital step
