I followed an online tutorial.
Dug an old 12 VAC power adapter out of a box which had a few of them it.
Paid a few cents for a 6 AMP rectifier diode at Radio Shack.
Soldered as indicated.
If I put my clip over the diode, I'm etching into the steel.
If I bypass the diode by clipping under it, I'm making a dark mark onto the steel.
I had Ernie make me some stencils, and 'Tada!'
Works great!
I will be making a custom pad just big enough to cover my stencil, so I can etch the whole area all at once. The Q-tip thing works, but I can do better.
