This is such an amazingly simple thing to do that I’m surprised it shows up so consistently on HN. A raspberry pi or similar, a solar panel, a charge controlle

This is such an amazingly simple thing to do that I’m surprised it shows up so consistently on HN. A raspberry pi or similar, a solar panel, a charge controller, and a battery. Running everything off it (router, modem) would be cooler, since that’s likely powered from the home and connected via WiFi.
