F32 – An Extremely Small ESP32 Board
As part of a little research and also some fun I decided to try my hand at seeing how small of an ESP32 board I can make with functioning WiFi.
In plain words
F32 is a minimalist ESP32 development board designed to explore how small a functional WiFi-enabled microcontroller can be. Created as both a research project and experimental exercise, the board maintains full ESP32 capabilities in an extremely compact form factor. It is intended for developers and hobbyists interested in space-constrained IoT applications or those curious about embedded systems miniaturization. The project is available on GitHub.

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:…
