Simple Etcher for Maker's Mark
This is by far the simplest version of any electrolytic etcher. It can be used to etch and mark carbon and stainless steel. Coupled with a quality stencil, clean and professional results can be produced.
The adapter can be any AC adapter with a voltage around 12 VAC. The diode can be any common 6 A general purpose rectifier diode (Radio Shack or any electronics supply house will have one that will work.) A few daubs of silicone to secure the diode to the adapter case and we're off and running. If you need advice on the pad, there's some detail on Page II of the Poor Man's Etching Power Supply series.

Happy New Year!
P.S. I have updated the Radio Shack links as they changed their site. November 10, 2015.
