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.

Amazing how fast it works
Item Package Quantity: 1
This works so much better than the prescription cream I got from the doctor. I thought 40% was the highest available. Ease of use and it goes exactly where it's needed. Saw improvements after the second day of use.

Amazing cream to restore cracked skin!!
Item Package Quantity: 1
Cracking of my feet is not the problem. This has been the only cream I found that restores my cuticles!! My right thumb constantly stays dry and ugly. The convenience of applying like a ChapStick is wonderful. and allows me to grab and apply frequently. My cuticle has finally become soft and pretty. :) (Highly recommend)

Absolutely great. I’m a repeat buyer.
Absolutely LOVE this toner. My skin is slightly sensitive and this formula NEVER burns my face. Great exfoliation. No tightness or dry areas. Fantastic for the price and just as good or better than name brand or expensive toners. I’m a repeat buyer. Big bottle and lasts a while. I would highly recommend.
