As we all know, when aliens descend from outer space, they often beam bovine up for testing and observation. While you might not have the privilege of seeing this process in action, “OneldMONstr” has created the next best thing: a miniature model of a cow being beamed up, complete with smoke and lighting effects.
The device features an Arduino Nano for control along with WS2812B LEDs. The lucky and/or unfortunate cow is spun using a small DC motor via an L293D driver, and a coil produces smoke with haze fluid.” (Though OneldMONstr notes the next version will implement an ultrasonic hazer.) A DFPlayer Mini MP3 module is embedded in the base for sound, while a half dozen LEDs illuminate from the bottom. More details on the project can be found here.
