Forgive me, I am sure this has already been discussed but...

I don't know if air is required or not so keep that in mind.

From the little I have read so far, you need agitation, not actually
air. Air is just a way of moving the liquid around for the
agitation. It also seems that most of the rigs for this are vertical
to accomodate the rising air.

Would this work...

A shallow, flat tank, sitting horizontal. Across the center is a
pivot point and at one end a very small, slow spinning gear motor
with a cam on it. The cam rubs against the bottom causing the tank
to rock back and forth. This would cause the liguid to move back
and forth in a wave motion.

Adding a couple of standoffs to the circuit board before putting it
in the solution could be used to keep the board off the bottom of
the tank.

If nothing else, it might be relaxing to watch it rock back and
forth :-)
