wtf is pulseforge?

PulseForge is a collection of small, fast web based utility tools aimed at people who program microcontrollers, work with Arduino and ESP32 boards, or do general electronics and maker projects. The whole site is built from plain HTML, SCSS styling, and vanilla JavaScript, with no build framework and no backend server, so it can be hosted anywhere as static files. Each tool lives in its own folder with its own page, styles, and script, but they all share a common set of design building blocks such as colors, spacing rules, and reusable components, so every tool looks and behaves consistently. The site is designed mobile first, meaning it is built to work well on small phone screens by default and then adjusted for larger screens, with specific attention paid to things like the navigation menu collapsing into a hamburger button, and buttons resizing to be easier to tap on narrow screens. A notable feature is the built in accessibility system. A small floating button appears on every page, opening a panel where visitors can adjust font size, font family, cursor size, light or dark mode, and one of seven accent colors, and these choices are remembered between visits. The button itself can be dragged around and will snap to the nearest edge of the screen, and it remembers where you left it. Currently the site includes a handful of ESP32 focused tools covering things like PWM signal generation, timer interrupts, and a reference for the chip's input and output pins. The pin reference data is sourced directly from the chip maker's official documentation rather than unofficial diagrams, since these details can affect safety. The README also explains exactly how to add a new tool to the site: create a folder with the standard three files, reuse the shared styling imports, and register the tool in the homepage's list so it shows up in search. This makes PulseForge a useful example for anyone who wants to build a simple, fast, framework free set of developer utilities of their own.
