These seem to be pretty common on eBay, so I got one to take to bits.
The circuitry is quite evolved, with a microcontroller controlling both the ultrasonic atomiser disk and also a boost circuit for stepping the voltage up.
There are locations on the PCB for extra filtering, that have been bridged by zero ohm links. I'd guess the designer wanted to keep their options open. That's also reflected in the extra LED position, allowing the PCB to illuminate a water container directly. I'd guess this PCB may find its way into other products too.

Now we need a incinerating extinguisher to put it out.
The effect of this is pretty cool looking. I have absolutely zero need for a humidifier in the Pacific Northwest, but it looks cool lol
The MOSFET drive line from the MCU? It should probably be capacitor coupled to the gate. Otherwise if the MCU crashes the gate could get stuck high and that would be bad.
Any thought about what frequency that transducer is being pulsed with?
Your audio quality sounds off. I think there's too much low and mid tones but not enough treble?. I don't know but it makes your words VERY hard to distinguish from each other.
Has your airbnb host noticed that their small appliances are getting picked off like cattle under a UFO? 😄
A very good Monday morning to you all from Wellington Somerset
If you get used to things looking like they're burning when they aren't, when they are, you ignore them and things go downhill from there..😄
I thought at first oh nooo… CLIVE'S toaster is on fire.😂😂
Very interesting device, I've never seen it before.🥰
I'm holding out for the desktop fire breathing dehumidifier.
Now for the Big Clive mod of the day.
Add a set of 18650 cells and charge controller to make it battery powered.
"You've seen it working, now let's take it apart!"
So now it's no longer working. 🤡🤡🤡
