No problem. It's a pretty basic design. I built it after seeing this
one-
http://www.embeddedtronics.com/etchant.htmlMine looks about like that. I just checked, and it's about 11" x10"
x1.5" (h/w/d). I have the luxury of a radial arm saw here, so I was
able to do grooves for all the joints on mine. Be careful with the
adhesive and test thoroughly for leaks with water or something
beforehand. There's a lot of pressure on it when it's full. I figured
I was extra safe with the grooves AND some old silicone, and once it
filled up with water, it started trying to stretch itself open. I had
to remove all the caulk, which left a nasty film of goo and re-glue
with better stuff, and I think I still need to reinforce with some
fiberglass. There's probably a fish tank adhesive that's better for
it. I haven't needed the inside standoffs he used yet. I hung my board
from some fishing line hung around a magic marker and looped through
both top corner holes in the PCB. It stayed pretty well centered.
It wasn't much trouble at all considering it should solve a lot of my
over-etching problems. I may, however, regret my dimension choice
though. I wanted to be safe if I did larger stuff, and went with that
size and a 10" heater. The heater has a "keep filled to this point"
warning line on it, so it looks like I'll have to fill the whole damn
thing just to do small stuff. I may grab a smaller heater too and
figure out how to drop it down low. I've got a dual outlet pump
connected to two suction mount "bubbler" tubes which will sit
horizontally at the bottom. It puts off plenty of "fizz", so one
outlet would have easily done the job. I'm planning to mount the tubes
to a heavy plate of plastic or something so I can drop them down to
the bottom (you can't access the insides of this thing very well).
BTW- I have a bad habit of going straight to eBay for everything
lately, and assume it's the lowest price. I got the pump there and
then realized I could ride up to PetSmart and get a heater for less
than on eBay. They had like 6"-12" on clearance for around $6 to <$15.
Mine was $8 or something. I had to wait a couple weeks for the pump to
use my tank.
Try it, you'll like it!
