Drew,

Good thought, but the weather has been bone dry.  Today it's 100F in the equipment area with a RH of about 10%.  I'm in shorts & t-shirt and the sweat is evaporating as fast as it comes out :-)

I am beginning to suspect thermal shutdown on a linear regulator.  As the temperature has climbed I am seeing the problem with greater regularity.  I need to get back to my office to look at the gumstix schematics to find places to probe the 3.3V supplies.

Thanks for helping with the brainstorming!

Steve

Total shot-in-the-dark, and probably not worth trying unless it's
easy, but what about dewpoint?  Is condensation an issue?  (I don't
know much about environmental effects on electronics.)
