Mental Screening
Self-tests to screen for common mental health issues.
What it does
Should you get help? I made interactive, auto-calculated mental health self-tests presented in simple, step-by-step user interface. The self-tests, or "questionnaires", are made according to validated/peer-reviewed psychological questionnaires made by mental health professionals/academics - all have been used in clinical/research settings.

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:…
