Hey everyone, I wanted to share a custom hardware and software ecosystem I’ve been building over the past few weeks to create an alternative to traditional, highly distracting tablet screens for my kids. I call it CueHub. It acts as a dedicated, ambient home display driven by a Raspberry Pi CM4 hooked up to a 16" portable touchscreen monitor, serving as the central hub for custom ESP32-S3 wearable devices that I put together. How It Works: Instead of a crowded UI with keyboard inputs or an app store model, it uses a zero-friction voice pipeline. The kids press a physical button on the ESP32 device, state a natural command, and the Pi CM4 triggers dedicated local micro-apps that render real-time visual data. The Core skills in the video: Live Air Traffic Control: Pulls live flight data globally via the OpenSky Network API, mapping density via H3 hexagonal grids and regional rendering via MapLibre GL tile maps. Commands like "Show me all A380s" or "Zoom into SFO" process instantly.…
