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.

Best electric corkscrew - by far
I have tried others but this electric corkscrew outshines them all....so far. Really like it. I have been disappointed with some before though if you get a very dry cork that splinters.....but this one has a much smoother operation and just works better. Good price too.

It is light weight, rechargeable and it works hands-free.
This wine bottle opener is well designed and well constructed. It comes with a foil cutter and works hands-free when you push the button. It pulls up the cork - and then pushes it back out to discard the cork. It is rechargeable!! It is replacing an older opener that left behind cork fragments in the wine - and ate AA batteries quickly.

Best on the market!
I have tried three other brands of electric cork pullers. The fact that I now invested in a fourth probably telegraphs what this review is all about: this Vinabon device is great, hands down winner in the electric cork puller sweepstakes!
First, its motor is more powerful. Some winemakers are employing corks that fit pretty tightly, and the other brands I used would occasionally be unable to remove the cork. The screw would simply stop turning, without ay way of resuming. Advantage: the bottle.
Second, it is small, about half the size of the others, leaving a small footprint on the counter.
Third, it lasts much longer on a single charge. It doesn't sit in a cradle, because it doesn't need to. Assuming you open 10 to 20 bottles a week, you will be able to go two weeks without needing to plug the charging cable in, and a full charge does not take long. 4 vertical lights on the cylinder tell you how much of a charge remains.
Fourth, you simply press and release the start button and maintain gentle pressure on the bottle while the device descends into the cork and removes it. As soon as you remove the device from the bottle, it immediately begins to eject the cork. All with that one touch of the button!
Fifth, if you encounter a particularly tight cork, the device will stop, whereupon you push the button again and it continues. A couple of synthetic corks required me to restart 3 for 4 times, but it ultimately conquered them all!
That leaves only one issue: a failed cork that breaks during the removal process, because the screw cannot engage the cork enough to remove it without it breaking. To my knowledge, the only solutions to this, with any cork puller, are to resort to an Ah So, or if that cannot do it, just shove the cork down into the bottle, and drink the entire bottle in one evening.
Truth to tell, I have, myself, actually enjoyed that latter remedial step, especially with a larger format bottle on an evening when I am dining alone.
I cannot yet report on the ultimate problem that seems to vex all electric cork pullers I have owned: If the cork disintegrates within the cylinder during removal, how do you get the remains out? I threw my last cork puller away because I could not remove the cork detritus stuck in the cylinder, rendering the device useless thereafter.
If there is a solution to that, I would not be surprised to find that this unit already handles the problem.
If BMW were to ever make an electric cork puller, I expect it would be much like this one.
t costs almost twice as much as the others I have owned, but you get what you pay for. After all, you can buy a small fleet of Yugo's for the price of a BMW.
Bravo, Vinabon! I

Best Wine Opener ever
I hoped I made a wise choice to buy this wine opener and boy did I make the right choice. I have had 2 other electric openers and this is by far the best. You place it on the bottle and press the button once. You hold the bottle and opener and the opener does its job, you don't need to hold the button down. Once it pulls the cork turn it up side down and place it on the counter. It automatically stops and then automatically reverses and ejects the cork. You dinner guests will love watching it. Great opener!!!!!!

Nice little wine opener
Nice little wine opener. It works perfect so far , it doesn't take up a lot of space on your counter. Fast shipping.
