Subject: RES: [Leica] Dry chamber for storing camera gear

The problem with dessicant(sp?) in a halliburton case is that you have to
figure how much dessicant should be used. And it will come to a point in
which it is fully loaded with water and will not absorb any more. So, even
with the kinds that change color when loaded, it´s not a matter of use and
forget. A drybox will need less maintenance.

Cheers,
Amilcar

I've been thinking for a while of making my own dry box using a peltier
chip.

When running normally, the peltier chip would cool below the dew
point and condense moisture on it. That would drip from the bottom of
the chip/heat exchanger into a drip pan that would lead outside the
box.

Every  x hours, I'd run the chip in reverse to make sure that it was
freezing the condensate.

It *should* work, although how well is unknown.

Then again, at an auction today I just bought two (2!) Zero
Haliburton cases at $25 each. They're sealed, so with a little
dessicant in them, they should be perfect for storage of my
preciousess. :-)
