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.

Great product
Pretty great product. It's bit smaller than expected, but otherwise no issues

Made well. Precise control pouring spout. Stainless steel, not just coated.
Love this little pitcher. It holds up to 12 oz. It's stainless steel, not just coated, and a decent weight. I love the design with the precise control of the eagles beak spout, but I still can't do the "art" very well. The etched numbers inside make a huge difference between making a Cappacino or Combacha as the difference to a lot of these coffee drinks has to do with how much frothed milk you add to your shots of Espresso, so having the etched markings inside is fantastic! The markings are not actually dug/etched INTO the stainless steel. Feels smooth inside to run your fingers over the etchings. Although I've washed it a few times in top rack of dishwasher the etchings haven't faded, so I'm glad about that. The etchings are dark enough to be easily seen. Measure in ounces and ml. Hopefully they will not wear off somehow. That's why I gave it a four star. It's very comfortable to hold and pour.
