Tim Brookes writes about seven projects you can build with the Cheap Yellow Display (CYD), an affordable ESP32 board with an integrated LCD touch screen that lets you skip soldering and breadboards entirely. The projects span a weather station, a Wi-Fi and Bluetooth penetration testing suite (ESP32 Marauder), a Bluetooth MP3 player, a retro mini TV for videos and games, a Gran Turismo 7 racing dashboard, a Home Assistant music remote, and an ESPHome smart home controller.
- The weather station pulls from both Open-Meteo and OpenWeatherMap and supports a DHT22 sensor for local temperature readings
- The ESP32 Marauder CYD port covers hardware from 1.9-inch non-touch models up to 3.5-inch touch displays
- The retro mini TV is a 3D-printed Simpsons replica combining the Anemoia-ESP32 NES emulator and MiniLegoTV video player
- The GT7 dashboard works because Gran Turismo 7 publishes telemetry over UDP on the local network, a feature shared by other racing simulators
- The CYD Jukebox pairs with Music Assistant to unify local files and streaming services like Apple Music behind one interface

ESP-Claw is an AI agent framework by Espressif that enables ESP32 series chips to function as active decision-making centers rather than passive executors. It implements a full intelligence loop involving sensing, reasoning, and execution locally on edge hardware. Through conversational programming via chat interfaces, users can define device behaviors using dynamic Lua loading without traditional coding expertise.
