Hi Folks,

	Wow!  That brought a lot of requests!  If anyone is interested in looking
at some of the designs that I did for some of my junction boxes, I made a
real quick web page.  Please feel free to download the drawings, e-mail me
with any comments, or send large sums of money :-).  The drawings  are not
specifically designed for housing temperature loggers but can be adapted
for that use.  Just remember, I am not an engineer.  I am a PhD student
working in optical oceanography.  I am self-taught in CAD and UW housing
design.  Also, Tom Peacock (our boat captain and ROV/AUV tech) deserves a
lot of credit for helping me with these designs.  I am open for any
suggestions for improvements to these housings and will add any designs
that anyone else would care to contribute.
