Description
A smart project by MatixVision: a 3D-printed flat bas-relief lunar surface, a circular enclosure with backlit clock numerals (1–12), and a desk stand. The result is a lunar desk clock: it sits on its own stand, while an OLED display underneath shows the real-time date and time.
And it goes much further: Alexa voice control, real lunar phases via API, audio playback, and even a Space Invaders mini-game accessible from any browser on your local network.
A smart project based on ESP32-C3 that combines lighting, sound, and interaction. Using a WS2812 LED strip, the device displays dynamic effects such as 🌙 Lunar Phases (synchronized through an online API), 🌈 Rainbow Effect, and 🌫 Fade Effect.
It also includes a ⏰ Clock & Web Game, audio powered by a MAX98357A amplifier with an 8Ω 2W 28 mm speaker, touch sensor control, automatic brightness adjustment via an ambient light photoresistor, and Alexa integration for voice control of the main functions.
