PreamblePreamble

Recently I found in the Internet at a very cheap solution for etching PCB. To make it you need components which total cost not more than $0.5.
Previously, I etched with ferric chloride, and then used sodium persulfate, which does not stain. However, the solution I found is better and faster that both of them!
