Solar project update: started off at 4.12 volts, and after two nights of shining bright LEDs (and one overcast day yesterday) the battery got as low as 3.71 volts. But today was mostly sunny, and at last check it’s charged back up to 4.13 volts again! I think we’re in business. https://twitter.com/josecastillo/status/1576413906243055616
