Hi HN, I’m a solo founder. I built ProblemHunt after noticing a common pattern: many founders start with ideas and solutions, but don’t spend enough time understanding real problems. ProblemHunt is a simple place where people share problems they actually face in work or life. Developers and founders can browse these problems and use them as a starting point for building products. So far: – ~5,000 users – 150+ real problems submitted – 100% organic growth This is still early, and I’m trying to understand if this is genuinely useful. I’d really appreciate feedback: – Would you use something…

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:…
