Hi Mags!. Nice video.
Do you have any ideea why the cap is charging to 20V while still pumping juice to the coils?

Do you mean in my vid?

No Mags.
In my case nr 3.

I see it in the drawing now. 

Your first coil is acting like an inductor in a boost power supply.  If you increase the cap value, your cap voltage will go down. Smaller cap, voltage will be up from 20v.

Depending on if your switch can handle it, you might get better results with a small cap at higher voltage.  Or, if the second drive circuit is triggered long enough, longer that it takes to empty the cap, then you might benefit from a larger cap at a lower voltage.

Try some different ones to see.  ;]

Thanks mags!
I'll try different caps.
