The Kit
The hardware behind the logs. Each item leads with what it is and why it is the answer, because the advice has to stand on its own even after any given product goes away. Most of it is used, borrowed, or already in the closet.
Nobody pays me. I bought the gear myself. There are no affiliate links, no ads, and this site makes no money. No prices either, because a made up price is still a lie.
