My Acoustic Levitator is a USB-powered ultrasonic levitation device for levitating light-weight particles. It works great with styrofoam particles up to 4mm in diameter.
I became really interested in the concept of ultrasonic levitators and wanted to purchase one for myself. However, I was unable to find a well-designed and affordable option. So, I decided to come up with my own design.
My Acoustic Levitator is powered by any USB 3.0 power source and allows for levitating particles at a distance of 10 cm (4 inches). The levitation field is able to levitate lots of particles at once and is strong enough to keep the particles stable even when the levitator is moving or rotating.
This particular design-style was chosen to minimize any ultrasonic reflections hence making the ultrasonic field as strong and stable as possible. The symmetric geometry was chosen so the user is able to position the levitator in different orientations.
Inside the levitator is a microcontroller that is responsible for generating the 40kHz square wave. It is accompanied by a DC-DC converter and an H-Bridge IC to drive the 14 ultrasonic transmitters.
The Acoustic Levitator comes delivered with a USB-cable and a piece of styrofoam to practice levitating.
