I wrote down every expensive hardware development mistake I've seen
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…
In plain words
The Hardest Hardware Lessons is a guide documenting common costly mistakes in hardware development from prototype through end-of-life. It covers the full product journey including thermal validation, manufacturing processes, component obsolescence, factory operations, and field failures. Designed for hardware teams and engineers, it compiles recurring pitfalls that are typically avoidable, offering practical insights to help teams prevent expensive missteps during development and production phases.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
