how do i make an aluminum electrolytic capacitor? Answered
i want to make a capacitor bank with high capacitance and i saw a lot of instructables for high voltage, but the most i got out of one was with aluminum foil and plastic wrap and i only got 14nf. i saw on some sites that the aluminum was electrocoated with aluminum oxide, but i couldn't find any specifics and nothing i tried so far has worked (it just created higher resistance, not capacitance). also, what's a good electrolyte solution, i'm just using water, salt and baking soda.
