Back to dealing with things somewhat under my control....
I think the dealership-installed replacement 12V battery in the Venerable Prius may have been new-old-stock or otherwise stale; it doesn't really hold a charge for a whole week. (Mind you, until this year the car didn't generally sit anywhere near a week un-driven; 'twas my daily driver, meaning really almost daily.)
So, I've ordered another one from an on-line source. Not all that much money, even with shipping. Were we going into stores, I'd look in person and check the date codes, assuming I could actually find such a specialty battery in a store, which seems a bit questionable.
And, we'll be trying to line up contractors for spring/summer work: driveway repair and extension, exterior work on house and barn, transforming the seasonal swamp into a year-round pond for aquaculture, and so on.
In the slightly less mundane category, I need to design a custom Aard-Wino type of board: usual ATmega328, plus management for a solar-charged LiFePO4 cell, a header for a COTS nRF24L01+ module, and a few other features. Might actually get that done today, and sent out to fab. It's for a sensor birdhouse, and, since I figure on building several of them, I'd just as soon avoid a bunch of tiresome and error-prone hand-wiring.
