Some links on this site are affiliate links. If you buy through them, we earn a commission at no extra cost to you. It never changes what we recommend.

Amazon Associates

As an Amazon Associate, this site earns from qualifying purchases. Product links — including the books on the Books page — may carry an affiliate tag. Prices, formats, and availability change on Amazon; any price we mention is approximate and accurate “at the time of writing,” not a live quote.

Our rules, in plain English

• Recommendation first, link second. Every hardware pick has to survive one question: “Would we still recommend this at 0% commission?” If the answer is no, it doesn’t get recommended.
• If the best product has no affiliate program, we still recommend it — and say so.
• Affiliate links are marked with rel="sponsored", and a disclosure appears above the first affiliate link on any page that has one.
• No fake scarcity, no invented discounts, no “lowest price” claims.

Affiliate revenue keeps the lights on. The blueprints — not the commissions — are the business. If that balance ever drifts, we fix it.
