I've spent years watching hardware teams make the same mistakes — tooling committed before thermal was resolved, manufacturing processes not validated in PVT that only showed defects at volume, components going EOL unnoticed until the factory tried to order them. The pattern was always the same. The costs were always avoidable. Nobody had written it down. The result is The Hardest Hardware Lessons — covering the full journey from first prototype to end-of-life: EVT/DVT/PVT, factory evaluation, supply chain risk, mass production operations, field failures, and product lifecycle management. https://thehardesthardwarelessons.com

Could you build this?
No This is an informational book containing hard-won physical product and hardware engineering insights, not a software product that can be vibe-coded.
What it would actually take: Requires decades of real-world hardware engineering, factory bring-up, supply chain operations, and manufacturing experience (DFM, thermal design, PVT qualification) that cannot be simulated or coded into existence.
