How to make Ultrasonic levitator at home | full theory explained | Acoustic levitator 

Wow, I've never heard of ultrasonic levitation before, nice job!

Pretty cool. What is the mass of the object you levitated and how much power did it take? In other words, what's the efficiency, weight that it can lift per Watt input? I'm wondering how it scales to large objects? I'm sure it's very inefficient, but it would be cool to know how much power you'd need to lift a person.

You need to orientate your six transmitters to converge to a central point. Here you simply put them vertical with same effect as only a single on top and single at bottom.

The number of transmitters does not mean heavier load, more transmitter increase stability of the levitating object. Bigger levitating object bigger transmitter is needed. Plus, the transmitters has to be at a 25-35 degree angle pointing at a converging point; here is a better explanation, 2 transmitter: a straight line up and down, easy to find the zero point in the middle, 4 transmitter: (very hard to do but possible ) 2 up 2 down is a one dimension triangle, and what you have is a 3 sided triangle. the more transmitter you have the shape changes. from the center of each transmitter is one leg of the shape you created. the tricky part is at what degree of tilt will they work best. The bigger the project, the steeper the angle. Try a diamond shape object to levitate. hope this help.

During ultrasonic operation, can you feel a noise or slight vibration? Thank you very much.

4:58 How come you eliminated the aluminum laminated capsule? Did doing so improve the performance?

Everything is okay. But can you please tell the distance between transmitter after you attached every other components

I am looking for a cue to make my own ultrasonic microphone. Better if it was of the type that is in contact with any surface like something like private investigators. :) . I need it to detect my neighbors who are making a 'purposeful use of voice suppressor and various noises, 24\24H. You can hear something (but you can hear at a considerable distance but my neighbors are 5 meters away from me divided by the dividing wall), since they use non-professional instruments that work but leave something to be desired. I also perceive so called "quiet" noises and very annoying vibrations. Now I am waiting for a kit to arrive, which is based on "heterodyne," so I will be able to hear (because they are converted into audio audible to the 'human ear) ultrasonic frequencies whether they are animals or people who use them disproportionately ... .

Can you spray some dust in the air, and film this interaction in slow motion? You should essentially see the nodes.

Muito bom! Parabéns!!! 😀

you should add more ultrasonic sensors and put them in a bowl shaped manner on updside and downside so they could concentrate easily at any object in the mid .....

You should angle all the transmitters so that they converge at a point and form a static wave to hover the object 5:32 👍

create a metal cover that focuses to one point for each set of the three transmitters. Like a horn shape. The vibrations will be imparted into the metal and will focus the levitation wave i.e. wave pocket.

🤩 nicely explained, good work bro, keep going 😇

The +/- connections to the transmitters s very important: If one of the transmitters is 180 degrees out of phase with the other 2 the levitator could not focus 3 beams to a point.

FYI.. TIP: By coupling an optical device using the Schlieren effect to a high-frequency camera, and emitting high-frequency, high-intensity sounds, we can visualize the variations in air pressure and therefore see the sound.

Are the transmitter and receiver on one module, both usable or only the transmitter?

I compiled your sketch for an ATTINY88 and it passed. I'm thinking , the Tiny88 and a TA6586. I'll go build it and let you know.

Try to change angles of transmitter. Use curved shape instead of flat surface.

This is great, I will give this a shot. Thanks for sharing mate

bro in your website you have added the transducer the the same pin why cant we use the different pins??

Bro place the transmitter at an angle. It will work.

Can you provide the code you used in arduino

Good explanation dude! Nice work

Great content, keep going 👍

How is one of these emitters manufactured? Is it possible to build a larger one?

What is the type of jumper wires

can you write all of materials name please this is very important for my project

The 3 sensors should be pointed in 1 poit

How do you know which of the two is the sound emitter?

Can we actually increase the distance to make it more taller

Hi sir, I was doing your project for university but some problem seem to troubling me can I contact you for discussion. I am also at the end of my project time

can i use 9v battery

We can use this technology and make it more powerful so that we can use it on vechiles with thruster on back for speed . wait can it levitate with only one ultrasonic levitaer please answer

I was trying to replicate the project. But I was not able to levitate anything. Then, I realized that I am not getting any output at the output ports of the driver circuit since my multimeter is not showing any voltage. That could be the reason why I am not able to levitate. But otherwise the driver circuit is working fine with simple motor arduino codes. Is there anything that I am missing out?

Can u please say me we can also make with those 28 pin ic base,16pin ic base , 16mhz crystal, 10k resistor??? Y dont u used it? Please reply

I'm new to all of this and I've 3d printed a holder for the two ultrasonic sensors with a distance of 1 cm, but I tried and it didn't work, so do I have to turn it on and off really fast or something, because I must be missing something.

Actuaaly the distance between the transmitters were not correct due which levitational force was not produced as the force of levitation is produced when the ultrasonic waves of the top and the bottom transmitter meet and form a single wave. To do that you must keep the transmitters at different distance from each other and find just the right distance for levitional force to be produced

Awesome !!!!! Nice job.

How many weight can ultrasound lift?

Good work

you should put little drops of water in it to levitate

Sir i need to contruct this project can i get your help for the materials required in this project

Can I use a receiver and transmiter to levitate small objects?

Does it notice which ends of the speakers are connected to each other?

Best video ❤️✌️

Can we use speaker that is above 32 khz to levitate?

Hey I have thought what if you increase the distance between them so that you could get the perfect region where node and antinode do not meet

I tried it even I got a minute noise from sensor but it's not working why?

what if i supply 9V instead of 7.4?

can i copy the code from website to aurdino app directly ?

awesome

What is the distance between the transmitters?

The transducer are not coming out of the board

Super 😍😍

Where can I get the code

🔥🔥🔥

Hmm, maybe you need to properly measure the distance the two ultrasonic speakers are... then you'd know for sure where the node is. The dust idea is also great I think.

Where u r frm bro ...

Bro code plz

What program did you write for the arduino?

❤️

See: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XpNbyfxxkWE.html for why the setup with 3 inducers might have failed.* Edit: And also the precautions you should make. Edit 2: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-So2VK5xnLyI.html might also explain why your setup failed. Edit 3: You might want to search _"ultrasonic transducer"_ on eBay. There I found for ~17€ (+free shipping) an 60W transducer means for about ~34€ you have a real powerful setup. Which is a lot more expensive than using those modules (I found one offer for 10 modules for 10€, means each transducer ... if you are using both sides cost you 0,5€. But IMHO those 20 are combined less powerful than the other setup) *=Ok, in case it wasn't clear. If you are even a tiny bit out of the area of the standing wave, then it will not work. Even tiny height differences might break the setup. You might want to build it in a way you can change the height precisely after you installed them. Do you have access to a 3D printer?

You should take upper cover of the sensor Then find a result

Bro you can give free ultrasonic sensor to me

sir i made but its not working

The size of the object you wish to levitate must be smaller than half the frequency of the transducers. @ 40K the object can't be larger than 4mm. This video may help you: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vURtf8uGsFg.html
