It's a point.  Actually what I probably ought to do is plain retire the
blue-wired board and slap another Adafruit HAT on cu.

(BTW, the reason for the two-letter names is that I can fit them on Avery 5412
gummed labels which in turn fit on the non-electrode surface of a micro-SD.)

Yeah, I thought about that.  I didn't because (a) the Official
Windowsill of Mad Science is running out of room for pucks to be
deployed on, and (b) if I put them there now they're likely to become
victims of Zola's attempts to fine-tune his measurements of the
gravitational constant.

(Very nice cat, he is, but an inveterate physicist. Never when I can
see it; when I'm *at* the Great Beast he's most likely to be found
curled up and purring just past the right end of my keyboard.)

Once I get the rack built I can put pucks on top of it and tape
them down.
