AppealSeal

What it does

This is our first full launch! Until now, appealing your property taxes meant hiring an agency that took 30% of your savings or spending hours doing it yourself. AppealSeal makes the whole process effortless. With higher interest rates since the COVID years, it’s more important than ever for homeowners from the last 6–8 years to check if they’re overpaying. No one likes overpaying in taxes!

  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:…
