[@wrightian5291]

What blows my mind is the efficiency of the design, shorter wiring, easy interface (in terms of the final product). This is amazing ✨💫💯

[@maxcurrent485]

Finally a tractor beam for the common man! Now if you can just make some DIY hoverboards and force fields. Then if somebody makes some DIY flying cars and quantum teleporters and warp drives, that'll knock out most of the best sci-fi tech come to life.

[@TheMirelyght]

we still need an effective death ray....for....reasons. i'm looking at you mister not using your turn signal.

[@maxcurrent485]

The military has them already. They're called "free electron lasers".

[@orionl.8491]

I want to make a handheld levitator so I can do that thing I did in my dream, clean my room using levitation.

[@IgorDz]

Can you make a bigger version for my UFO saucer? This one can't lift a cow

[@he-man4076]

You need to get subsonic. Oh wait, cows are smaller than 17 meters and larger than 1.7 cm.

[@urgirlcassie23]

I wonder how far out could this reach theoretically if you used a larger, shallower parabola. Or how large a mass you could control with more powerful industrial grade transducers with crazy high decibel ratings. If you dynamically manipulate the angles of the transducer array to change the focal point, it could probably pull or push objects or even launch objects instead of just holding it there at a fixed position. There're probably more advanced things you could do with the harmonic layers, too... The interference pattern could have the side effect of pulsing the air like those soundlaser things and make an area with audible (deafening) sound if it's designed wrong... Maybe not though.

[@rodbender9076]

So much patience. Thank you for producing the video. Your machine sounds like a kitten purring. This item still requires its creator to operate independent. Obtain singular independence. Builder is a robot? So fast!

[@Turambar3791]

I can't wait for "Build your own Launch Control Room, Launch Umbilical Tower, Saturn V, Apollo and Lunar Module by yourself" video!!!

[@jimmy_jamesjams_a_lot4171]

Wow?! An array of carefully aimed ultrasonic transducers to create a convergence of standing waves! I thought there would need to be deflection from a wall just beyond that point? I’m seeing the results, and it’s baffling, just how cheap and ‘back yard’ that device seems to be?! I would have thought that there would be so many different careful things to consider. He carefully and knowingly checked for the polarity of the transducers. I don’t even know how much volume of fluid to put in my ultrasonic cleaner, or even where I might look to find the formula to make that calculation. This guy must be the one I should ask! The future looks brighter thanks to demonstrations such as this. Thank you very much for sharing this!!

[@gaungthin]

Very cool, and I like your wiring and assembly skills. Do you also have something that explains the theory of phased arrays and how they can "tractor" material? If you were able to modulate the frequencies for each transducer individually, while managing the phase, could you move the object around?

[@UpnaLab]

We have two Open Access papers that try to cover the principles of phased arrays and tractor beams: www.nature.com/articles/ncomms9661 aip.scitation.org/doi/full/10.1063/1.4972407 . The device of the video can move particles up and down, we do this by changing the phases. You are right, in a normal standing wave you can use small frequency variations between the two sides to create a travelling wave but in the tractor beam the only way (so far) is changing the phase.

[@bradleygunn3364]

[@atye04]

Awesome, way over my head, but what kind of soldering iron is best. Tired of crap soldering irons. Also solder sucker recomendations. Thanks!

[@megfan9377]

Here's how to make your very own sonic tractor beam for less than $70 Step 1: Buy a 3-D printer.

[@ardonjr]

Or go to Ikea and buy a plastic bowl there.. You might also be able to use it. But I get your point.. I know, by the way, that there are print shops in the Netherlands (for instance) where you can send you design to and they will set their 3d printer to work. So you don't have to buy one yourself.

[@NateBluehooves]

3dhubs. you could just pay somebody else to print the bowl. :P

[@Y--H]

There are plenty of 3D printing websites, so you don't have to buy your own machine.

[@dhanang]

Yeah I gave up on that first step

[@calebcain6396]

so I just have to go to the Netherlands?....might be cheaper to buy a 3d printer now

[@crispychicken2743]

Nice job. Try a drop of water or Mercury see what happens

[@JacksonJDoyel]

Is there a way to tell if they're out of phase without buying a $250 dollar oscilloscope?

[@Dubswitcher]

Could it be possible to use a regular, appropriately sized bowl if done carefully?

[@ajcastro-chandri2427]

Can you share your Arduino source code? Maybe also a build-sheet of componentd? The 3d print file would be awesome. Thank you.

[@UpnaLab]

www.instructables.com/id/Acoustic-Tractor-Beam/ I still need to change the description.

[@acvtfassociation8386]

Bruh it’s in the description

[@JeremyCook]

Nice (and very nice editing too - can't quite put my finger on how you're varying the speed, but looks good!)

[@apus.k.t7424]

Which software to use for the arduino uno

[@jasonmskidmore]

Curious how changes in atmospheric pressure and/or composition would affect this.

[@Pemj2k]

You sir are thinking critically. People at different elevations may have to change the design or calibrations based on that thinking.

[@milankarakas3005]

No noticeable difference.

[@UntrackedEndorphins]

I can't wait to build one!

[@Donthefirst]

yes same! ;)

[@edusson]

Awesome work, both in the device and the video!

[@milankarakas3005]

Question: why there is just 10 V peak to peak? Some transducers can go up to 150 V p-p, I usually do it between 60 and 70 V p-p, no damage. Or those black transducers are so poor quality?

[@miguelmdfk2994]

Felicitaciones desde Colombia sur america y pregunto,si aplico este principio de levitacion acustica,en una camara de hidrogeno,podre' suspender plasma??? Usando el gas como combustible???.Gracias.La idea es hacer que la fision nuclear no requiera sobre esfuerzo a los magnetos del tokamak.Animoooooo.

[@JanicekTrnecka]

picture of Red Dwarf... Episode LEGION...popped in my mind

[@aminoshift1158]

That's a really neat idea

[@he-man4076]

Good luck with the noise when you need to use audible frequencies to levitate large objects

[@he-man4076]

@TILEN FABE However, the audible frequencies' wavelength are in the range of 1.7cm to 17 meters. Most, if not all foods reside in this range. Obviously doesn't include the people who likes their rice come grain by grain.

[@chrisbutler9594]

I wonder if something like this could be scaled up into a form of repulsor lift, for a landspeeder like setup

[@popterrace8658]

How much was the cost for all the pieces?

[@bilcon56]

can you do the same experiment by getting the speaker turning it upside down and letting vibrations to control the lift

[@johnspain8714]

I'm curious as to how noisy this tool is in operation, the overlay music is nice but it sort of obscures that detail

[@constantinoweddingfilmes]

It's not possible to hear without a microfone.

[@MrPosbi]

so would it be possible to build one large enough to levitate something bigger,say a car? or would that just screw around with peopes senses?

[@Pemj2k]

I'm no expert, but if you can move the frequency out of the human hearing range and keep the same forces, then maybe.

it's annoying to look at, never mind the sound this abomination makes.

high mass dictates different design principal and would require something such as magnets and electricty to pull off . This is low mass as those things 'levitating' are little foam balls with basically no weight or mass. This is not a tractor beam - it's not pulling anything, it's just trapping the foam in small vortex of air current .

[@svenkund234]

doeas anyone have a complete circuit diagramm of this device ? I can`t find one on the instructables site...

[@DrGonzo-jl9wq]

Wow, incredible video. Loved the editing!

[@alienween1491]

If you were to focus the sound into a compact beam would it go a greater distance and if it would how would you do that

[@valdemirjs]

If one were to be built with the necessary strength would he be able to levitate a human being?

[@leviatorproject6626]

Yeah, acoustic levitation is theorically supposed to be able to, it would be awesome. But there is some material limits like the size of the transducers or the input voltage needed...

[@usmanpirzada2201]

Sure, can be done. If you don't mind becoming deaf.

[@index7787]

The vibrations would be quite violent, it would really mess you up, and you would go deaf

[@aerox_odyssey]

The object might have to fit in the half of the wavelength but I am not sure :/

[@psycronizer]

seriously ?! can you imagine what kind of devices would be needed ?! they would have to be operated by chemical explosives to produce powerful enough shock waves and still have to be operating at least thousands of cycles per second and that kind of punishment would literally pummel a human into a lifeless floppy rag doll, all bones would be broken and internal organs munted. consider the experiment where American scientist's used timed explosions to self propel a metal drum up into the air, one was let off every second or so from inside the open end of the drum to make it fly up, you'd need that, but in reverse and many of them all aimed at YOU....what a way to fly and DIE !

[@apus.k.t7424]

[@davidkempton2894]

Very nice video. And very clever! I saw an article about this only the other day in an email I received at work.

[@samgadd6046]

I think magicians like David Copperfield have been using stuff like this to make items float for years and they're just now figuring out that it's easier to make than thought

[@stefanopozzato3964]

I loaded the sw on 3 arduinos, but nothing comes out, no waves, the programming listing seems to be faulty

[@justchillin6420]

Hey I have no clue how to do any of this which classes would I go to start learning about this type of stuff? I’m currently in high school almost college

[@68rajamanu63]

Sir can u tell me plzz which Which type of components Nd divises. Are u use

[@TheKrimzonGhost]

I thought sound waves couldn't propagate in the vacuum of space would this only have atmospheric borne applications?

[@TheKrimzonGhost]

What if a shielding gas was released around the object you are trying to capture could the sound waves propagate within the gaseous cloud?

[@625dennisk]

Jeff Mezzanotte Where in the vid does he test it in the vacuum of space that makes you ask this?

[@TheKrimzonGhost]

To claim it's a legit tractor beam it has the expectation of working in the vacuum of space otherwise it's just a sonic atmospheric turbulator.

[@pedroff_1]

Jeff Mezzanotte but, wouldn't the gas quickly disperse, especially in a low-pressure environment?

[@nathanlewis42]

Of course it wouldn’t work in space. It is an impressive accomplishment though.

[@anthonyrickard1272]

Question instead of using the Nano Arduino is it possible to use a regular Arduino uno

[@jumbi1306]

Yes

[@Gachetos]

You are using only transmitters?

[@felipeurbano655]

Vendes todo para armarlo?

[@greenghost7907]

Now turn the bowl upside down and make it at least 30 ft in diameter. make sure your vessel acts as a dialectric waveguide lens and synthesize the force of gravity (or anti) and use that to publicize attempts at new flight capabilities. Now watch the MIB knock on your door in just a few days!

[@tommcmahon1471]

If you were to hook that up to battery with a higher ampage would the device be able to lift heavier items...

[@RavenWarrior90]

Unless you don't fry the circuits with such batteries... yep I suppose that might work. But this is not a real tractor beam, it emits a field inside the dish but not outside. It's a levitation tool, but no tractor beam. Tractor beams lift objects up to a specific distance but here you cannot speak of distance. Hmm... seems like we will see professional tech in near future, anti-gravitational devices and stuff like that. One day we might use that for vehicles. If any normal person can do something like that with such "primitive" components, professional research organizations might improve the technology and make it usable for a variety of things. Hovering cars, cleaning devices, "weapons" for law enforcement to capture criminals very quickly and without doing any harm, personal hovering devices similar to jetpacks. Mass Effect is coming closer to reality :D

[@blower05]

how big is the power consumed by this kit?

[@robcab3725]

Asier, The l298n module is giving me unequal voltages out 1 and out 2( 3V) < out 3 and out 4 (12V). I got a new module and it gave me 9v and 12 v respectively. both at 25v input . Any ideas where the problem is.

[@robcab3725]

The jumpers coming from the arduino are only 3 v each, not 5 v like in the video

[@megamitomegamen8735]

What is that thing on the middle

[@hqcart1]

how many lbs can this lift?

[@malcolmadams2105]

Is there a sound to be heard or is it sub-sonic to the ears?

[@he-man4076]

It is ultrasonic

[@ricardomolina8773]

Can you do the same With sub wolfers

[@robb233]

Great video. Question. Does the acoustic hot spot effect the path or scattering of a light beam? How quickly can it be repositioned in that case? Cheers

[@UpnaLab]

Thanks. I think it would work, I could be wrong but I think that is how optoacoustic modulators and some techniques of field scanning with a laser vibrometer work.

[@robb233]

Asier Marzo Im thinking of the recently launched Holovect Kickstarter campaign that produces free floating vector holographic like displays. Curious if theres an overlap.

[@robb233]

Here's the project if you're interested: www.kickstarter.com/projects/2029950924/holovect-holographic-vector-display

[@UpnaLab]

I was very impressed when I saw that project, but then some people say that it just blows columns of fog and that most of the footage are quite 2D. A focal point in air does not affect light much, but in fog it could have an effect. We have tried to control fog with ultrasound but it is not very effective, perhaps strobing the light at the fr of the sound so that it is synced with its tiny vibrations. Sorry, not very into displays. In any case, we will try to keep opening our ultrasonic devices so that everyone can do research with it.

[@robb233]

Ive exchanged a couple messages with the holovect creator, sharing some of my own whirlywig volumetric contraptions. He seems pretty straight up guy. Theres a 30 minute tech show where he shows off his device to the host as well, but you're right, Id definitely love to see some vids of a static cube, where only the camera is changing position for example to settle any questions. Interesting points about the fog and tiny displacements. Maybe there's some other behaviour going on with refraction for example. Anyways, again, very cool demos with your tractor, and thanks for all the technical info you share! Cheers

¡Estupendo trabajo! Enhorabuena

[@casseyclarke7172]

Hi, Is it possible to send more than 1 signal through the wire to create a wave of the same affect, without having to worry about the angles of the transducers or do they have to be on a certain angle? Can you also create a magnetic field from coil and convert it to ultrasonic waves? Are you able to make a helmet that can produce theta wave stimulation of the brain?

[@1238a8]

It is possible with shift registers. However, it's not one, but 3 wires. Of course it's more expensive and complex.

[@joesmith4546]

I don’t see any dimensions for the bowl itself here or on the instructables site. What’s the diameter, and what’s the measure of the arc?

[@hannahe6936]

well, you can get the bowl from these places to see for yourself if you were looking for it cdn.instructables.com/ORIG/FM7/UD6W/IWMQUV05/FM7UD6WIWMQUV05.stl www.thingiverse.com/thing:2749157

[@joesmith4546]

Thomas, the point of me asking is so that I might be able to recreate the curve of the dish without using a 3D printer, which I both do not own, and have no money for. I don’t see any details related to the diameter and angle measure of the arc on the websites you posted.

[@giyanvice]

This is not a Tractor Beam, it's a Levitator. None of you nerds figured it out? Tractor Beam: A tractor beam is a device with the ability to attract one object to another from a distance. Levitator: To rise or cause to rise into the air and float in apparent defiance of gravity.
