I spent a year making an electro-mechanical prototype of a liquid clock
In plain words
An electro-mechanical liquid clock that took a year to prototype and develop. This novelty timepiece is designed for people who appreciate unconventional, mechanical art objects. The clock uses liquid movement to display the time, combining engineering with visual interest as a desktop or display piece.

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:…
