Hey, new to the forum. I've been trying several different designs for a homemade capacitor. I'm interested in antique electronics such as old radio's etc. So I like to make as many of the components as I can. But I'm having a baffling problem with my capacitors.
Just as a test, I started out using a plastic film canister wrapped in aluminum foil for the positive terminal. I inserted a steel nail in the lid to act as my negative terminal. I filled the canister with plain salt water. I've attempted to charge it using between 9 and 12 volts DC without success.
My second attempt was to use a flat section of plastic with foil on both sides. This also failed.
This is one of the few components that I've failed to make over the years. I must be missing something. I've even gone back and studied other designs and watched others build them exactly the same way. But I'm at a loss as to what is missing from my designs.
Any ideas?
