I wanted to make a nice handsome label plate for the Jacob's Ladder, so I decided to experiment with brass etching. Basically, I followed the steps outlined here except I used PCB etching fluid (ferric chloride) instead of doing it electrolytically, since I had a bunch on hand.
( Pics, as always )

Handsome? It's goddamned spectacular. I'm very, very happy with it. Next time I'll make sure the etching is a bit deeper -- I suspect electrolytic really is the way to go if you're doing this a lot. But over all, it worked great. Absolutely worth the effort.
