DIY Acoustic Levitation Electronics for Standing Waves DemonstrationFeatures:
.Feature：Working voltage：12V; Size：42mm X 26mm X 53mm(H); Suspended object: foam ball; Button K1 K2 not support (Reserved function) .
.The new PCB is changed to octagon.LED (red) power indicator，while LED (yellow and green) ultrasonic suspension indicator.The output voltage amplitude is 24V, measured with a multimeter, and the AC file is about 33.9V
.The suspended foam ball is stable, Ultrasonic probes are matched to ensure that they float successfully every time.It can still levitate after lying down. It has strong levitation ability.and the strong hands-on ability can provide the self-welding of the loose parts.
.Mini Acoustic Levitator: This is a mini ultrasonic levitator device that can suspend foam balls. The device is composed of a MCU STC15W, a driving chip TC4427EOA and two 16mm 40KHz ultrasonic probes. Mainly used for students or DIY electronics enthusiasts to learn about ultrasonic standing wave levitation.
.Working principle:Ultrasonic standing wave levitation is through the existence of a certain distance between the ultrasonic transmitting end and the reflecting end (or another transmitting end) (called the distance of the resonant cavity), the transmitted wave and the reflected wave (or another sound wave) are continuously superimposed and finally form a stationary Wave, the sound wave force received by the object at the node of the standing wave overcomes the effect of gravity and finally achieves the effect of levitation.
.Note: Harmonics are easy to be generated after ultrasonic superposition, resulting in squeaking sound, which can be solved after the distance is extended, but it will lead to poor suspension ability.

A MUST Buy for your TEEN.
Helping my son so much - these work within a couple of hours to flatten ouchie whiteheads. My 14 years old son is so grateful!
There’s 2 sizes, 22 patches, and they truly are “invisible” like the box says.
These have been working so well (better than any other brand - and we’ve tried them all) and the price is the cheapest. We Love THAYERS brand now - lifetime user here for sure.

Good buy
Size: 6 in, Color: Blue
A winner with our GSD. He’s not a super aggressive chewer but it has still held up and is a favorite.

Terrific toy for heavy chewers
Size: 6 in, Color: Blue
My dog loves this! Chews and plays with it constantly. These will last a long time, however, eventually they begin to break down. THEN GET ANOTHER, lasted a couple months with constant chewing.
