Independent engineer United States

I build small systems that do useful things.

I’m JS. I work with Raspberry Pi and ESP32 boards, write firmware, and build the web interfaces that make a project understandable.

Projects and notes

A few things from the workbench.

Browser experiments

Three small tools: replay a CSS animation, mix a color in HSL, and measure reaction time. They run in the browser, with no account or upload.

HTML / CSS / JS

Embedded debugging guide

A practical checklist for checking power and wiring, reading serial output, narrowing symptoms, and keeping a record of what changed.

Raspberry Pi / ESP32

This site

A small static site built with semantic HTML, Tailwind CSS, and a little JavaScript for the mobile navigation.

Vite / Tailwind

Season /

A note for this time of year.

The seasonal note updates through the year.

Seasonal notes and listening

A note from JS

I like knowing why something works.

That usually means following a problem from the physical setup to the code and back again. Sometimes the fix is a loose wire. Sometimes it’s one line of CSS. I write down what I find so the next person has a place to start.

This site is where I keep the projects, notes, and experiments I want to share.
