That said I believe I read this configuration(boost & cable) was capable of delivery 40v peak to peak.
i doubt it...
if you combine 2 output voltages of 10V, you get 20V maximum... But if you have a link to an explanation on how to do this without messing the waveform please share it.
I wondered if you placed the sample directly on the plate or did you use some form of applicator?
The Spooky2 team sells an adhesive tape which does probably not affect the electromagnetic field much.
So what i do is that i cut a small piece of tissue on which i put a drop of my blood (make sure to disinfect the needle with fire or alcohool or hydrogen peroxyde before piercing your skin to get the drop of blood), then i put the small piece of tissue on the scotch, then i put the scotch between the 2 coils of the spooky 2 remote (it must be between the 2, not above or below)
