Recirculating Desiccant

[Tom Droege <tdroege2@earthlink.net>]

Last night I ran for the first time with the pump that recirculates the air 
through the desiccant.  This is definitely the way to run.  The desiccant 
was not noticeably pink after running for several hours.  The images were 
clean and free of ice crystals.  Congratulations to Michael R. for thinking 
of this.  (Even though he thought that was the way I designed it.)

I recommend that you all change the desiccant loop to recirculate.  I had 
no trouble modifying a fish tank bubbler to recirculate.  I just drilled 
and tapped a 1/8 NPT hole in the case and installed a fitting.  Then I 
glued everything together with RTV.  First tests are that this works fine.
