Refined GitHub vs Sensor Playground

Refined GitHub is a Safari extension that simplifies the GitHub.com interface and adds useful features. ■ Highlights - Linkifies issue/PR references and URLs in code. - Makes whitespace characters visible. - Reduces tabs’ size to 4 spaces instead of 8. - Adds one-click merge conflict fixers. - Adds reaction avatars showing who reacted to a comment. - Adds a button to revert all the changes to a file in a PR. - Adds a build/CI status icon next to the repo’s name. - Adds a button to view the source of Markdown files. - Shows PRs that touch the current file. - Highlights the most useful comment in conversations. - Shows the first Git tag a merged PR was included in. - Adds a link to an automatic changelog for each tag/release. - Adds possible related pages and alternatives on 404 pages. - Displays the age of the repository in the sidebar. And so much more! 200+ features. See the developer website for a full list of features. The GITHUB and REFINED GITHUB trademarks are owned by GitHub, Inc. and used under license.

Sensor Playground turns your phone into a live dashboard for DIY sensor nodes built on the ESP32 or a Raspberry Pi class single-board computer. Flash the free companion firmware onto your board, wire up a supported sensor, and the app finds the node automatically on your local network or via Bluetooth LE — no cloud, no account, no registration. Readings appear as clear cards and live charts, updated in real time. CONTINUOUSLY GROWING Development is ongoing: updates ship regularly, and support for new sensors is added continuously. If your favourite sensor is not on the list yet, chances are it will arrive in one of the next updates. HIGHLIGHTS • Automatic discovery of sensor nodes over Wi-Fi (LAN) and Bluetooth LE • Live cards and charts for every measured quantity • Air-quality rating derived from IAQ, CO₂ or eCO₂/TVOC readings • Dedicated screens for gesture, distance and contact sensors • Send bitmaps to an SSD1306 OLED display node • Signal-strength badge for Bluetooth nodes • °C/°F switch, English and German, screen-reader friendly • Everything stays on your own network: TLS-encrypted and API-key protected — no cloud involved SUPPORTED SENSORS (and counting) • Environment & air quality: BME680, BME280, SCD30, SGP30, MCP9808, SHT31, SHT41, AHT10/AHT20, CozIR-A • Light & optical: SI1145 (sunlight/UV), TCS34725 (color), analog light sensor • Motion & orientation: IMU 10DOF, MPU6050, MMA7660 • Infrared temperature: MLX90615 (non-contact) • Positioning: Air530 GNSS/GPS • Event-driven: PAJ7620 gesture, VL53L0X laser distance, button, hall sensor, magnetic switch, PIR motion, vibration • Display: SSD1306 OLED (128×64) GOOD TO KNOW • You need at least one sensor node: an ESP32 or a Raspberry Pi class board running the free, open companion firmware. Arduino sketches and Python scripts are available for every supported sensor. • A built-in simulated sensor lets you explore the app before any hardware is connected. • Scanning and discovery are free for all sensors. Data visualisation for a few selected sensors requires a one-time in-app licence purchase, which supports the ongoing development. Whether you are a maker, a teacher, a student or simply curious about the air in your room — Sensor Playground makes hardware experiments visible.
