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.

Uncomplicated; comprehensive reading! It was a good buy!
The task of preparing a will is very daunting. I was ready to give up and hire a lawyer for my small estate. This book addressed all of my concerns and then some. There is even a section for information on each state's laws. I know what I need to do now. The book will now go to the executor of my estate. He will appreciate the comprehensive coverage of each subject.

Format: Paperback
Pretty good book on being executor of a will. It list most every step needed from A to Z. May be helpful to get one that is state specific to get all details needed.

fast bathroom touch-ups
Great for fast bathroom touch-ups -- that four-times-a-day wiping away drips, toothpaste, and splashes. Sensitive formula won't dry out your skin. These are great to have on hand.
I buy tons of these for disaster prep -- when there's no water, it's nice to have a way to keep fresh. Also good for barter, if SHTF.
