There are so many little details.

For example, I spent a couple hours cutting and splicing USB cables to 2-pin JST 1.5mm connectors. It's one of the steps the is largely invisible (even to me) until it's suddenly very obvious that you don't have a way to conmect the solar panel to the node.

I was going to poat it on a hacker project site, but they never got back to me. 🫤
