I made one from a 5 buck plastic aquarium from Walmart and an old
aquarium air pump ... It has a plastic grate that goes in the bottom
so I took a piece of hard plastic tube, drilled a bunch of holes in it
and have it below the grate and run a flexible plastic hose between it
and the air pump .... one thing I also had to do was seal up the holes
in the lid but a piece of clear packing tape did the job with little
fuss ... i also rigged up some holders/hooks from some plastic I bent
with some heat to help position the PCBs
Worked out pretty well for me, I etched a PIC frequency counter PCB, 2
PCB's for a Pic n Mix, part of the boards for the PIC a STAR, and a
couple of boards for a digital milliwatt meter and only had to make
repairs to one board but that was due to the photo paper I was using
(Epsom Glossy Photo Paper) Most of the boards were made with Staples
Photo Basics Gloss (#471861) which has worked flawlessly for me so I'm
sticking with it
