DIY a Fascinating Acoustic Levitator

Using an array of 72 40kHz ultrasonic transducers to form standing waves of low and high pressure, the maker Julius Kramer has just created a 3d-printed acoustic levitator. 36 each are placed in the top and bottom shells of the device’s chassis.

What’s interesting about Kramer’s build is that he does a great job illustrating how it works, starting at around 3:00 with an oscilloscope, and continuing on with diagrams, and even a visualization of the waves using steam.

The transducers are energised with a square wave generated by an Arduino Nano. This allows the possibility of the frequency and phase of the wave to be altered, which can help tune the device and allow some movement in the vertical axis.

So let’s take a look at Julius Kramer’s video.
