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:…

Codecademy.com, the easiest way to learn to code▲787
I've been a longtime member @ HN, but I haven't been a developer. In fact, my only HN submission has been one asking how to learn to code (http://news.ycombinator.com/item?id=820741). My cofounder and I decided to solve the problem by making a simple, interactive way to get started with Codecademy. We'd love your feedback. If you're interested in helping us to get more courses up (on any topic!), please send us an email at [email protected].

New way to search for used cars (my weekend project)▲160
Each dot on the chart is a car. Horizontal scale = mileage. Vertical scale = price. The size of a dot = year (newer = larger), plus I colored 2007 .. 2011 in different colors to find "fresh" cars quicker. This is just some sample data from the last 24 hours, relatively cheap cars under $32,000 within 500 mile radius of NYC.
