Southern California
The home yard, next to the lab. Builds go here first, so the easy mistakes get made close to the soldering iron.
Each outdoor build is installed twice: once in a test yard in Southern California, once in a test yard in Ghana. Same plan, same parts list where possible. Then every lesson gets sorted into one of three bins.
One yard tells you a build works. It cannot tell you why. Was it the design, or was it the weather being kind?
Two very different yards pull those apart. If a lesson shows up in both, it is probably about the build. If it shows up in one, it is probably about the place or the rules.
That is the whole trick. It is cheap, it is slow, and it is honest.
The home yard, next to the lab. Builds go here first, so the easy mistakes get made close to the soldering iron.
The second yard. A different climate, a different power and network picture, and a different parts shelf. The same build has to stand on its own here.
That is as specific as the locations get. No addresses, no faces, no names. Hands and hardware only.
True anywhere.
Lessons that should hold in any yard on the planet. If it only worked in one yard, it does not belong here yet.
Changes with climate and infrastructure.
Lessons that depend on where you are standing. The build is the same. The weather, the power and the parts shelf are not.
Changes with regulation.
Lessons that come from a rulebook, not from physics. These are notes on what the build ran into. They are not legal advice. Check your own local rules.
One sentence. What happened, on which build, in which yard. No theory yet.
Would this be true over there too? If nobody knows yet, the lesson is tagged “one yard so far” and it waits.
True in both: Universal. Changed with climate or infrastructure: Geographic. Changed because of a rule or a permit: Rules.
A photo of hands and hardware, a slice of the data, or the exact change that fixed it. No evidence, no lesson.
Lessons live on the project page and in Field Notes, each with its build code and its bin. A lesson can move bins later. The move gets logged too.
