Corrections welcome, gear not
If something here is wrong, we would rather hear it from you than leave it standing. Say which piece and which paragraph.
Corrections and technical disputes. Point at the sentence. If it is a measurement or a standard, tell us what you measured and on what; if it is a topology claim, name the circuit. Corrections are made in the text itself, not appended as a note at the bottom.
Questions about your own patch. We read them all and answer some, usually by writing a piece rather than a reply. If your question is already the subject of a piece, expect a link and nothing else — that is not a brush-off, it is the answer.
Manufacturers and distributors. We do not accept review units, we do not run sponsored articles, and we do not take a fee to mention a module. Partnership means funding the writing and appearing in the supporters band on the homepage — nothing inside an article, ever.
Repair requests. We are not a repair service. If a module is faulty, the manufacturer's own service channel will do a better job than anything we could tell you, and knowing when to stop is itself covered here.
