Replace the control electronics in a Levoit LV-PUR131 air purifier with an ESP32 that runs ESPHome. The result is a local Home Assistant fan entity. No cloud account, no vendor app, and no WiFi module in the original product.
This document holds measured numbers, a wiring diagram, the reason for every component, and the ESPHome configuration.

Browsers cannot launch inside nono.sh sandboxes on macOS. The Seatbelt
kernel sandbox blocks Mach IPC (bootstrap_check_in) and xattr syscalls that browsers
require for multi-process communication.
What we tested:
Stack: Angular app with Three.js embedded directly (~1MB in the JS bundle). No GSAP, no Lottie, no external animation libraries.
Three.js + scroll-driven interpolation. The cube is not one mesh breaking apart — it's two sets of PlaneGeometry faces (split state vs. assembled state) with the visible cube interpolating between them:

A Quicken for Mac data file (circa 2007-2008, Quicken Mac 2007) was provided as a macOS bundle directory with no working copy of Quicken available to export from. The goal was to extract transaction data (dates, payees, check numbers, memos, and amounts) into a CSV.

The star of the show is the canal's infamous bottom sediment, affectionately known as "black mayonnaise" — a thick, oily sludge that is in some places up to 20 feet deep. It's a lethal cocktail of:
| #!/usr/bin/env bun | |
| // ── Star Field ────────────────────────────────────────────────────── | |
| // Parallax star field that scrolls right-to-left in the terminal. | |
| // 3 depth layers, 256-color, differential rendering (only redraws | |
| // changed cells). Supports ASCII and Unicode glyph modes, adjustable | |
| // star density, scroll speed, and color saturation — all via hotkeys. | |
| // Made with Claude Code. | |

The Playwright MCP server (@playwright/mcp) defaults to Chrome (channel: "chrome"), expecting it at /opt/google/chrome/chrome. Chrome has no ARM64 Linux binaries, so it fails immediately. The browser_install MCP tool also fails on ARM64.
Claude Code ignores args and env fields in ~/.claude/mcp.json for the playwright MCP server — it always launches npm exec @playwright/mcp@latest with no arguments and no custom env vars. So --browser firefox, env vars like PLAYWRIGHT_MCP_BROWSER, and custom command wrapper scripts all have no effect.
