The Linux Throwing: Powering A Linux Server with a 0.3W Solar Panel #piday #raspberrypi @Raspberry_Pi

Square summary

Via hackaday:

There were two main challenges here: First, it would have to combine the smallest practical combination of solar panel, power supply, and Li-ion cell that could run the Raspberry Pi. Second, we’ll need to remotely activate and access the Pi regardless of where it is, as well as be able to connect it to WiFi without direct physical access. In this article we’ll be dealing with the first set of problems — stay tuned for the rest.

Power stages

It’s small, it’s solar powered, but other than lounging about in the sun, it doesn’t really do anything yet. Most computing hardware requires software and obviously this is no exception — so how do we make this into a lean, green, Linux machine?

In the next article, we’ll cover how to control this system via MQTT, set up remote configuration (for example if I need to change my WiFi password), and set up a reverse-SSH tunnel so we can connect to the Raspberry Pi without having to reconfigure our network to accommodate it.

The irony that my servers now get more sun than I do is not lost on me. I live near the equator though, and sunbathing for extended periods is an activity reserved for tourists – one that they normally learn to avoid pretty quickly!
