@Larson What all does the elder care entail? If it's just supervision, maybe you can provide it using your automation skills. Obviously, something better than merely, "I've fallen down and can't get up!"
As for me, I just yesterday purchased some emergency rations for my family in case Putin decides the only way he can "win" is to go nuclear on Ukraine. Cheap 30 year insurance that I hope I'll never need. I figure a 30 day supply is enough, as the most intensely radioactive fallout is supposedly pretty well decayed (well, relative to the initial amounts) by then. i.e. as long as you're not blown to bits or incinerated, allegedly nuclear war is, in some sense, "survivable." Who knew? That said, even though the emergency rations are freeze dried, I figure it will make sense to monitor them over the next 30 years (their expected shelf life) to ensure low humidity in their container, as the instructions say to store in "a dry place between 50-70F." I figure one sensor per sealed bucket will suffice, and if my calculations are right I may not ever need to unseal the buckets again to change batteries! I'm not sure why temperature would matter to to shelf life (anyone know?), but dryness plainly does matter. If there were some way to store these rations in either the attic or the garage, which have much wider temperature ranges, without sacrificing shelf life, I'd much rather do that.
Why bother with all this? Well, if it hadn't been for Vasily Arkhipov, the world as we know it might have ended in 1962, though the story of how that very nearly happened wasn't learned in the West until 40 years later in 2002:

The parallels are striking. Who knows what kind of similar unforeseen escalation risks will happen this time around. For instance, David Petraeus says that if Russia uses a tactical nuke in Ukraine, then the US and Nato will kill every Russian soldier in Ukraine and sink every Russian ship in the Baltic. What hubris. And then what? All it takes is one submarine commander to feel threatened in the fog of war to justify unleashing Armageddon to defend himself and his crew. We now know that exactly that very nearly happened in 1962, all while the US wasn't even aware of the threat. Who is to say that it, or similar, couldn't happen again today under similar circumstances? 60 years may have passed, but I'm willing to bet that human nature hasn't changed one bit.

That is poetic.
I try to have some sympathy for my favorite (OSH_Park) and order multiple boards at once. Some pain of waiting is involved - only a week - and some waste is incurred by me as I correct my own errors before they ship. But I do like that they only ship three boards, instead of five, when I only need one. They must be annoyed by little-guys like me so I try to do my part with loyalty.

Wow thanks. That is exactly what I needed.
Thanks for the help, you are a champion.
