They seemed to thoroughly enjoy it. One asked, "you did all of this
in a week and a half?" "Uh, more like 5 days ... but I was
motivated!" At another juncture someone asked how I might choose
between welding processes as in TIG vs MIG. I gave several reasons,
including that TIG is much more amenable to precise welding of small
objects like "butt welding needles together." I got an odd look.
"Why on Earth would you butt-weld needles together?" I grinned and
said, "hey, I'm retired, I don't have to make sense!" They loved
it. These folks clearly care about what they do beyond production of
income. They see preservation and extension of quality life as what
they do. There are signs in the parking lot depicting active people
doing what they want to do. Welding was and is something I wanted to
continue doing, and by golly I'm doing it.

Having a customer that is a member of their peer group that has an interest in exploring
the fringe areas where their product will meet the real world had to make for a very
interesting day for them.

Your post recent update jogged me to play with a hall sensor I bought for a buck or so. It
notices my small sample pack of Neodymium magnets at about 7 inches. Worked fine after I
re-read the datasheet. Damn, wrong pins. At least I didn't fry it.
