v2.2.0: Add Yamanote E235 train favicon

Full favicon set depicting the front of a Yamanote line E235 train.

What's new

• Hand-crafted SVG favicon — green train body, dark windshield, grey Z badge, headlights
• All standard favicon sizes: SVG, ICO (16+32), PNG (16/32/180/192/512)
• Apple touch icon for iOS home screen
• Web app manifest for Android/PWA with Yamanote green theme
• Total favicon set: ~36KB — well within LittleFS budget

v2.1.0: Party Mode

What's New

• Party Mode — New button in the footer that cycles the status LED through random colours at varying intervals, giving the appearance of bopping along to music. Because every model railway deserves a disco.
• Clicking Party Mode keeps the throttle visible (no view switch)
• Clicking again returns the LED to normal status display

v2.0.0 — Nuxt UI + TypeScript

What's New

Complete frontend rewrite — the webapp has been migrated from Bootstrap 5 / vanilla JS / Options API to a modern stack:

• Nuxt UI — component library built on Tailwind CSS v4
• TypeScript — throughout the entire frontend
• Vue 3 Composition API — <script setup> single-file components
• Proper Vite project structure — composables, components, type safety

Frontend Architecture

• useTrainController.ts — singleton composable with all state, WebSocket logic, and ramping
• 6 Vue SFCs: SpeedController, LedTestPanel, DebugModal, DirectionInvert, TrainHeader, TrainFooter
• Icons via @iconify-json/mdi (replaces Font Awesome)

Documentation

• Updated all docs (README, CONTRIBUTING, CLAUDE.md) for the new architecture
• Added concrete macOS setup instructions with Homebrew, arduino-cli, and expected install paths
• Documented full WebSocket protocol including invert, led, and led_auto commands
• Added RGB status LED to hardware parts list and wiring section

No Firmware Changes

The ESP8266 firmware is functionally unchanged — this release is purely a frontend and documentation update. The WebSocket protocol is fully backward-compatible.

Full Changelog: v1.1.0...v2.0.0

v1.1.0 - Emergency Stop Visual Feedback

What's New

Emergency Stop Visual Feedback

• Status LED now blinks magenta 4 times when the emergency stop button is clicked
• Provides clear visual confirmation that the emergency stop has been triggered
• LED automatically returns to its previous state after the blink sequence completes

Technical Details

• Blink sequence: 150ms on, 150ms off, 4 repetitions (1.2s total)
• Magenta color: RGB(1000, 0, 1000)
• Non-blocking implementation in StatusLED update loop

v1.0.1

Documentation

• Add Fritzing wiring diagram image to README
• Update corrected Fritzing source file (.fzz)

v1.0.0 — First Working Release

The Nerdery Express is open for business.

What's New

• It works. Webapp served from the ESP8266, train controlled from any browser at http://ztrain.local
• LittleFS fix — corrected the mklittlefs image size (253 blocks × 8192 = 2,072,576 bytes). The previous value (252 blocks) caused a silent reformat on every boot, destroying all packed files. See docs/LITTLEFS.md for the full story.
• Configurable MAX_PWM — top speed is now tuneable via arduino_secrets.h (default: 500 out of 1000, roughly half voltage to the track — plenty for Z-scale)
• Railroad name — configurable display name shown in the throttle UI header and browser tab, sent via WebSocket status messages
• Build script improvements — dependency checks, correct LittleFS parameters, better error handling

Hardware

• Wemos D1 Mini (ESP8266)
• TB6612FNG H-bridge motor driver
• 12V DC power supply
• Z-scale track + locomotive

Quick Start

cp firmware/z-duino/arduino_secrets.h.example firmware/z-duino/arduino_secrets.h
# Edit with your WiFi credentials
cd frontend && npm install && cd ..
./build.sh   # Select option 7
