Mommotti’s Raspberrarium takes this simple concept one step further. By adding a Raspberry Pi and just two WS2812 LEDs, the Raspberrarium can accurately simulate, according to the maker: “a real daylight cycle (sunrise, noon, sunset), real moon phases during the night, [and] a smooth 24-hour light progression with minute-accurate transitions.” What that means is that even if your terrarium is in a part of your house with little natural light, it will still get the light that it would if it were outside. Even cleverer, the pair of LEDs mean that Raspberrarium can simulate the waxing and waning of the moon.
