Off the Grid

I am lucky enough to have access to my extended family's remote cabin. It's beautiful and remote (Figure 1), but there is no grid – no electricity or Internet, not even by cell service. I set up a solar-powered WiFi access point that hosts exactly one website: a place to share files. This lets the different people who visit the cabin exchange info with the next group who is staying.

My first attempts with a Pi Zero W model (released in 2017) showed that it was too slow, so I ordered a Pi Zero 2 W (released in 2021). It has four cores, and its speed is adequate.
