Mechanic says it's possbile that Mrs. Fungus' car may need an AC compressor. Cost: $600, though Rockauto.com reports I can get one in a kit with new seals and such for about $300, so if it does turn out to be the compressor I'll replace it my own bad self.
However, this issue does not occur except on hot days, which today is emphatically not, so there's no real way to tell. Because newer cars are finicky about the amount of refrigerant in their HVAC system, and because there's just no good way to tell how much is in there after all the fiddling I did (thinking it was simply due to leaking refrigerant, which it's not) he recommended evacuating and refilling the system first. That might fix it and it might not, but it will rule out an incorrectly filled system as the problem and the dye he added will allow them to pinpoint a leak should such become necessary.
Rockauto recommends replacing the condenser at the same time. I don't think it's necessary since the failure of this compressor doesn't seem to be the kind that fills the system with metal shavings and other detritus. Still, if that becomes necessary, it's a $50 part.
Menard's: LED bulbs are getting cheaper. Bought eight bulbs, 60W equivalent dimmable, at $0.99 each, and I'm going to replace a few bulbs here and there. Like the family room ceiling fixture, which currently has four CFL bulbs in it. LED is much better than CFL. One box of these LED bulbs is destined for that fixture.
Dimmable LED bulbs are usually more expensive than that. I'm not complaining.
Also picked up the 6mm allen socket I need for my work on the bike. $2 for the single one, or $13 for a set--I went with the one.

Last night I finally dug into my IBM Model M keyboard, to clean it. I actually pulled the cover off, and all the keys. I had to modify a toothbrush to make its head narrow enough to get between the key towers; but using that and a vacuum cleaner let me get all the cruft out. Wiped it down, then individually cleaned all the keys and reinserted them. Cleaned the casing (top and bottom) and eventually had everything back together again, and now this keyboard looks brand new, instead of
THIRTY-ONE YEARS OLD.
Yep: manufacture date, September 15, 1986. A fiver says it's never been cleaned; certainly it hasn't been cleaned since I got it in the mid-1990s. I'm amazed that the plastic hasn't yellowed, but then again IBM used to make its hardware to last. Except for a couple of nearly invisible cosmetic defects, it literally looks like it just came out of the box.
And works that way, too. There's a reason people love the Model M. Self included.
I had not previously been able to get the thing apart, because IBM did not design it to be disassembled with ordinarily-available hand tools. But when I still worked at Best Buy I bought a really nice precision screwdriver set, and it includes a nut driver of the right size with a thin enough wall that it can remove the screws on this thing. Score one for me.
The nice thing is, I have a spare in the basement, so if this one ever develops a fault, I just need to swap over a few keycaps (it's missing a few) and continue pounding away.
What can I say? Happiness is a clean keyboard.
