Explained projects
interval_buffer_isr: The Tiny Motion-Control Engine That Won’t Lose Its Phase
A stepper-motor ISR planner that carries sub-step position across frames, survives direction flips, and uses formal verification to prove the error stays bounded.
svg-term-recorder: The tiny recorder that makes terminal demos feel rehearsed
A Bun-powered TypeScript script, a virtual clock, and SVG output turn messy shell sessions into lightweight documentation assets.
The Visual Rebellion Against the Text-Only Terminal: Unpacking dbuezas/ghostty-config
How a web-based GUI and a custom Claude CLI skill turned a hardcore, configuration-driven terminal into an AI-managed workspace.
ftmotion-extrusion-simulator: FTMotion: Debugging 3D Printer Physics in the Browser
How a strict TypeScript port of Marlin's C++ motion algorithms turns the slow, wasteful process of tuning hardware into an instant visual sandbox.
The Browser is the New Oscilloscope: Inside usb-Input-shaper-calibrator
How a React frontend and the Web Serial API replaced Linux, Python, and GPIO wiring to democratize high-speed hardware diagnostics.
The Shadow API in Your Terminal: Unpacking claude-statusline-with-quota
How a TypeScript utility hijacks macOS Keychain and Anthropic's private endpoints to fix the AI developer's biggest fear (quota shock).
esp3d-homeassistant: Eavesdropping on the Extruder
How a clever Python event loop and a four-dollar microchip turned a vintage industrial protocol into a modern smart home integration.
BunBook: The Sub-Millisecond TypeScript Scratchpad
How a lightweight VS Code extension uses the Bun runtime to fix the "slow kernel" problem and make notebooks feel like native IDE scripting.
