Subject: Re: [Homebrew_PCBs] Re: ETCH TANK'S [COST EFFTIVE]

From: John Johnson <johnatl@...>

I was in The Container Store today. They had a few suitable items. One
was a magazine slipcover.
A collector's box for cereal boxes would be a nice fit too.

I believe I saw someone on the internet was using a foot bath to
agitate their solution. I believe the
tank was mounted on top. The aquarium bubbler is probably a better
solution though.

Regards,
JJ
