Ultrasonic atomiser and sponge box - Mist effect

I wanted to make an enclosure for the wg3166A board and, at the same time, make a box to put a water saturated sponge for the ultrasonic piezo element.

The idea, is to put it inside a pumpkin to create the mist effect coming out of the eyes and mouth of the pumpkin - Spoooooky!

The video shows the mist coming out.

The project is straight forward to make. The pictures are self explanatory.

You should cut a slot on the middle of the sponge to pass the piezo element wires through.
