[sdiy] Making a NP electrolytic out of two Polarized caps?

[elmacaco]

Thanks guys!!

I am skipping ordering an NP cap because I need only one and have a bunch of
Polarized caps here.  I don't want to pay $6 shipping for one capacitor, and
I want to finish this circuit over the weekend.

Thanks for the tips!

Ed
