Hardware on GitHub, indexed by what it is and whether you could build it.
Every project in the index carries a five-word description. Pick any part of one and the other parts narrow to what actually exists alongside it — so the sentence you end up with always has results behind it.

Each dot is one person. Hardware domains are fixed as poles; a person sits at the commit-weighted centroid of the domains they have actually committed to. Work in one field and you land on its pole. Split your time and you land between — the people toward the middle are the ones holding separate fields together.
Every chart below respects the filters set on the index, so you can narrow to a domain or a chip family and watch the same questions re-answer themselves.
Shares and distributions, not raw yearly totals. Discovery over-sampled recent repositories, so absolute counts per year describe the crawl rather than the world; dividing by that year's population cancels the bias out of both sides. The one chart that does show raw counts is labelled as such.
