While I admire the spirit and intention of this book—which is encouraging, never talks down to the reader, and genuinely tries to make the task of creating mechanical products approachable—I didn’t get a lot out of it. Maybe that’s because it already feels out of date; the sections on 3D printers and CAD programs read like something from a decade ago—which, from my limited experience, have come an extremely long way since then. Or maybe it’s because this type of learning, which is so tactile and physical, requires rich visuals that are lost in the book’s grainy black-and-white photos. Or maybe it’s because so much of the early content is made up of introductory geometry and physics lessons.
That said, the book does a nice job breaking down datasheets for components like hobbyist motors and ball bearings. It also provides plenty of examples of cool projects to attempt. While I feel a bit jerky suggesting that you’d be better off using YouTube, Reddit, and AI to figure out datasheets and project materials yourself, I think that’s undeniably true.
