Created 60 free useful tools in one place2025 · kewltools.com · ▲7
Hey there, I'm a solo dev behind KewlTools. So I'm one of those people who like to build their own tools/utilities whenever they a) want to get something done, or b) want to learn something. c) don't want to spend ages finding a utilty and going through walls of ads. I gradually built 66 tools, all free, fast, ad-free, and zero login. I (and my family/friends) use these daily, so thought some of you will find it useful! Any suggestions, improving current tools or adding new ones, please let me know.

Eigendrum - Draw any shape and hear what it sounds like as a drum▲243
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:…
