Electronic Fool's Day Fun: Capacitor Humidifier

 
Overview
Look, what a huge capacitor!
Look, this capacitor is smoking!!
Calm down, calm down, it's a humidifier. For April Fool's Day fun,
it can even play music? And display emojis? What kind of humidifier is this...?
A low-cost atomizer solution. As for the atomization module, a microcontroller? No need! A complex oscillation circuit? Also no need! You'd need a versatile EN555, right? Sorry, no need either. And RGB?
See, it's that simple.
Add a base to support this huge capacitor, add an ESP32 for easier control~~~~
Play music, display an emoji in the video below
, isn't this just a desktop pet?~~~~
Code attached.
