stc15w104 ultrasonic levitation

Overview

Hardware chip:
DC-DC boost: MT3608
40kHz PWM generation: stc15w104
PWM driver: RZ7899
Principle: Two sound waves of 40k produce a standing wave phenomenon, and very light and small objects can stay at the standing wave point.
According to another designer Description, the distance between the two emitters is the most suitable. You can adjust it yourself.

Then the copper pillars act as conductors.
