<div dir="ltr">I'd heard of / seen the 'redneck' cooler A/C units, but I guess I failed to realize how far along you guys are in exploring various cooling possibilities (I don't always keep up with the list as I should). I get warm enough in Snoopy that it's definitely worth the investment to stay comfortable. I remember when Alec and Steve were diving down in FL, a big bag of ice helped to do the trick, but was a little 'drippy' just the same.

As per AC, I also have a pile of them and been playing. The latest was an attempt to vacuum mold a Kydex cover for an experiment. No joy. I couldn't get the Kydex to vacuum around my mold before it cooled to much to still be flexible. I tried hitting it with
a heat gun while it was under vacuum, but that just melted it. Not yet discouraged!<br>

OTOH, I picked up a Yong Heng compressor for filling tanks whilst on the road. Haven't tried it yet, just got my activated charcoal and micro sieve material for the filter, but I want to use a peltier water cooling module to chill the water going into the compressor's
cooling jacket. The 6 chip one, with the water heat exchangers on the sides and cooling fins in the middle, has a design problem. The supplied fan can't pull enough air to really pull off the heat. Ordered a few sizes of radial fans to see if they work better.<br>

Back to Harold, for now sticking with a small insulated ice chest with a fan drawing air across frozen water bottles for my AC. Also dehumidifies.<br>
