Every guide works offline. Every guide is complete. Every guide is written by someone who actually builds this stuff.
Other sites give you Wikipedia. Hood's Finds gives you the bench manual.
Every build includes hand-crafted SVG schematics — readable, accurate, and printable. Not stock photos. Not screenshots. Original technical drawings for every circuit.
51 built-in JavaScript calculators. Bias point, impedance matching, antenna cut lengths, enclosure volumes — crunch the numbers before you cut the wire.
Every guide works from CD-ROM, USB drive, or your hard drive with zero internet required. No login. No expiry. Take it to the shop, the bench, the field.
Theory, parts list, BOM, safety warnings, step-by-step construction, testing, and troubleshooting — all 11 sections in every build guide. No skipped steps. Ever.
Written by someone who actually builds this stuff. Direct language, real math, and advice from hard-won bench experience — not textbook theory rephrased.
