UPDATE: There's some great information on this page and it's comments, but I've recently published a far more comprehensive article here: Etching Tins with Salt Water and Electricity With this project I wanted to try a number of new things: Magazine pages as cheap toner transfer mediaCopper electroplatingEtching Altoid tins with a salt water solution The copper plating met with mixed success, but the other two methods resulted in some nice pieces. Note: blue vitriol and muriatic acid are archaic names for copper sulfate and hydrochloric acid. Magazine pages for toner transfer: While looking for information on transferring toner using a fuser assembly from an old laser printer I ran across several websites where people suggested using glossy magazine pages for transferring printed circuit board images to a copper substrate. Preparing the Altoids tins turned out to be harder then I predicted. Next we: Copper Plating Altoids Tins: From the picture below, this appears to work. Foom!
