Electro-etching enclosures?

Hi,

Did anyone try electro etching on enclosure and had succes with it?
Just saltwater, some aluminium and a power supply and no nasty chemicals.

I just did a little test with electro-etching.
Did a toner transfer on some aluminum with my usual glossy-magazine-paper-toner-transfer method.
Mixed some salt with hot water and connected the positive terminal of my psu to a leftover piece of aluminum.
The negative to the piece with the toner on it.
Switched on the psu at 12Vdc and it immediately starts to fizz (quite hard).
After a while I checked and noticed that the toner starts to come of...

Was this due to the hard fizzing? The current to high at 3A?
Or the water too hot? Don't know but I'll try again in a few days.

Neat!  I've stayed away from etching because of the nasty chemicals.

Well it definitely sounds promising. How long did you end up etching? Was a significant amount of aluminum removed? Care to share pics?
