Blueberry Pancakes with Bacon! =)

I decided to unwrap these old BP Solar panels and see what they could do. I built a basic SLA charging circuit that would allow an SLA battery to be charged and to supply power to an ESP8266. This will be for use outdoors as a weather station "or something". I haven't decided yet. Mostly I just wanted to see if the solar panels that I've had for over a decade still worked.
