Two fixes today:
Refurbished two very old solar rock-lights. New higher power resin coated solar cells, new electronics which is basically a 4 lead chip and a small choke to replace a whole printed circuit that had basically rotted away and down to a single 2500mahr AA cell. Batteries in the charger and then out they go.
Here's what the solar cells look like:

See how much silicon there is in them unlike the trash they use these days. A quick test shows over 100ma at 2v in morning sun. Spec says 150ma at full blast. I got quite a few, as they were so cheap, for some projects I have in mind.
Got the filters out of the dishwasher, totally blocked up with gunge which explains why it was misbehaving. Plenty of elbow grease and they're now nice and clean. Once we have enough dishes I'll run a test.
