Wow. Pretty crazy. Makes me wish I were a young engineer, instead of a guy almost ready for retirement. But this gives me a great idea for what I might do once I am retired.
Its not to late yet. I started the engineering university the year I filled 40. And I was sure that I was going to be the oldest in class. I was not. No the oldest person in my is was 77 years old. He did not dolt for a career, but to keep his memory working. He did not do the final exam to get the completion of the course because he do not want to work as an engineer. In stead he started down the next five year program....
This is not the common project you can find on youtube, but this is an IMPRESSIVE project with a lot of work and a lot of theory behind. Congratulation for what you made and thank you so much to shared it! I don't think, by reading comments that people understood how much work you invested to realize this project/video.
My god, I don't know how old this video is but I wanted to make this/these back in 1994-95 (back then there was no Arduino or raspberry pie boards!) but my version was a cube with all of the transducers pointing inwards and to me, I was trying to think how a holideck would work and how to make it and this is it, now thanks to this guy and this fantastic video we might have them soon!! Please keep us informed! Take care and have a great day all!
That's what brought me here, I'm interested in the idea of using ultrasound for haptic feedback in VR. I envision something similar to your cube, six panels all facing the user from every axis, generating... whatever. Rain, wind, acceleration and g-forces for flying and racing sims, ground textures from the floor panel like grass, a rug, maybe water--imagine playing Kayak VR: Mirage and being able to reach down and dangle your hands in the water. The video title mentions haptics but the actual video, disappointingly, only focuses on levitation.
This is fantastic! You cover a lot of technologies from printed circuit boards, soldering, downloading and installing software, construction and testing etc. I think you should have gone slower. I think you covered every step that's necessary. But only 11 minutes for this very big complex project is maybe not enough. This is fantastic and amazing and very professional. Thank you
@@UpnaLab It sure seems like it. I would love to do a dual layer and am fortunate to have equipment access through my university and my employer. Hopefully I can get to it before the end of the year. I will be sure to be active on that page! Thank you for democratizing your research!
This is sick bro, maybe a little work to integrate the power and control section in the same elecronic board would be needed, but right now the result it's pretty fantastic. Keep it up!
Wow very cool project! I built a ultrasonic tractor beam device for my college project in physics electronics Autocad and got extra credit in math for an application. My device didn't use a FPGA though. Using software with it would have been awsome. 😮
very nice DIY project! would be even more impressive if it used monodirectional phase cancelation as a stop mid air instead of relying on a physical stop. still a neat trick, and thanks for sharing!
спасибо. прекрасный проект и прекрасные ссылки. каждый день не перестаю удивляться на сколько же быстро развиваются технологии и как далеко ушел прогресс!!!
Thanks for the update! I've been working on a project like this since I saw your BigLev demos. I'm working on a version that replaces the FPGA with a Teensy 4 and an external circular shift register. Currently trying to create my own driver to be able to run from your 3D Acoustic SIM software. Did you ever look into using the HV582, HV583, or HV57708, as a driver chip to drive many transducers in a single package?
I remember the brilliant Fauth giving a go at the HV* and giving up due to heating hackaday.com/2018/08/19/the-engineering-of-an-ultrasonic-phased-array/ Could you write me to asier.marzo@unavarra.es it seems quite interesting using a Teensy4 as a driver.
Excellent work. I'm only sad that RUclips is only leading me here so long after this was done. Fantastic project, are there any more materials available on the maths and algorithms that drive the array, the code in the FPGA and so on?
Your work seems to me excellent and with very interesting applications. I would like to know what is the spatial resolution of the particle positioning that you can achieve with this system.
The focal point is quite big (around 6mm diameter) but you can position it with high accuracy. I would say repositioning error should be below 0.05mm but I have never measured that. Absolute error will be higher since there will be reflections with the environment and other external affectors. In Page 7 there are some measurements but of a smaller system static-content.springer.com/esm/art%3A10.1038%2Fncomms9661/MediaObjects/41467_2015_BFncomms9661_MOESM593_ESM.pdf
Thank you for the prompt reply - This is so cool and something I really want to experiment and play around with!! To clarify, do you mean the width of each individual transducer, or the width/size (number of elements) of the entire array setup? Additionally, how would one think about the distance BETWEEN each focal point? meaning, how tightly packed could you get the floating beads and what is the max number of beads you could float? @@UpnaLab
Very cool project, now I understand why Sci Fi characters spend so much time calibrating various arrays, LOL. You could achieve a better packing density of transducers using a hexagonal array, what would be the benefits of this, I wonder, compared with the costs of doing so. I imagine better density would allow for levitation of bigger stuff, maybe higher distance. Accuracy, too? It would increase cost of the hardware, due to more transducers, at least, would the circuit board be complicated? I suppose if the transducer density did not allow for enough space for the back-mounted per-transducer components. What about the software complexity, as the array is no longer rectangular, I imagine it would be easiest to map a rectangular array to the transducers, would that be the way you would handle it? Again, fascinating project.
@@chain3519 Maths are not a problem when using numerical simulations. Hex packing is better but doing it in a single PCB with the electronics on the other side was the real issue.
Great video! I assume the only way of achieving all the phase difference for each sensor on such a matrix is using a fpga, so it is a great implementation.
Could a sonic or other array be the source of the mysterious Havanna Syndrome? These arrays create wave patterns at distance. Perhaps a room-sized array could do much more.
Impressive. Your just scratching the surface, as this has an application you possibly havent considered....cold fusion. I humbly recommend you get together with a team doing cold fusion experiments and see if you can find the majic frequency that will make the cold fusion cathode work. Again great job.
I hate idiots, but more so I hate people who pretend to be idiots. I would like to know which you are so I can calibrate my level of hatred accordingly.
A lot of patience went into this, but very impressive results. How much energy / acoustic force is required to levitate x amount of mass? With more powerful transducers, theoretically it should be possible to levitate more massive objects, but am wondering how far this experimentation has gone in that direction. Excellent demonstration of the phased array concept, and utilizing an FPGA to actually "steer" the array focal point(s).
1. got a question, could some kind of these be used for propulsion like a drone or something like that? 2. is it just me or this could be uded for those sand "holograms" shown in the black panther movie?
think the power needs would be to great, for what ever to get airborne, do you mean like star trek voyagers Doctor, some sort of Substance, to go with the light, maybe, but it still at the stone axes, and bear skin, stage at the moment?
You are a great thinker. What you describe is one part (Wp1.1) of what we want to use to make a volumetric display that you can touch directly without breaking your hand
With a feeding mechanism you perhaps could create a 3d display which could add or remove arbitrary number of points? How many 3d levitation points can you form reliably?
Wow. Pretty crazy. Makes me wish I were a young engineer, instead of a guy almost ready for retirement. But this gives me a great idea for what I might do once I am retired.
It may be better yet, to have experience and resources and the freedom to use them. Share your results!

You’ll just be that creep harassing otherwise normal people
You're just about to be reborn, so go for it!
Funny you mention retirement, I'm pretty close to retiring myself. Just got one last case before I do
I can't believe technology like this is so readily accessible through the efforts of people like you. Thanks

I hope you will blow up this year!
Thanks for your comment, but it is ok. Hopefully we will upload videos about how to build more cool devices.
This is quite impressive, a lot of work and science here, nice job!
Dear God. You put everything on it by hand . .. . . Crazy.

Yawn. Any slower, and I'd have fallen asleep.
Fantastic! Many would buy the finished product or a kit form.
I would demo for the five universities science programs in Kentucky!
why are the advanced tutorials always the most informative?
Bc.. they contain more info bc they’re advanced..?
With an interest in clinical ultrasound of course comes an interest in phased arrray transducers. This is really intense. Subscribed !!
Looks phenomenal! I've been wanting to build a phased array for a long time and this makes it so much simpler! Thank you!
It is still a tricky project. So hope you the best and do not hesitate to post doubts or comments on the Instructables.

Hello Sir, I am also working on my custom development board, on which software are you designing your PCB ?
It is amazing. I am interested in what you are doing here. I will go to check the published article.
Love how you say "Effpighiaye" :-)
very impressove but you should have put more example at the beginning because i couldn't figure what you where talking about until the end !

Seriously though, this is a great project, and as you have shown it has many applications!
Absolutely genius !!
Love it, from Montréal, Canada.

@@UpnaLab This is fantastic! If you wanted to dramatically decrease the focal point - to, say, .5mm - how would you think about going about that?
Either increase the apperture of the device (width) or using higher frequency@@patrickgumusoglu9201

Great black market electronics
Packing density could be increased with a non orthogonal layout.

Unbelievable work.
A phase steerable tweeter for super wide sweet spot.
And you made the first artificial gravity device when programmed with Linac Linear Accelerator type wave beats.
Can you make a video of a planetary simulation from 3D levitation?

This Is insanely awesome

wow! so cool! But how to improve the intensity of the ultrasonic?
Really amazing technology
Great stuff! Less than 200$!
i liked that intro beat
Impressive non ESD safety strategy there.😉. Nevertheless very interesting work.

Yes that could hold an astronaut to the wall.
This is so sick!!
good job, have an mathematics modelisation for that
Directed audio, very much on the lines of line arrays that use constructive interference
Can the board levitate itself
This!!! All day this!!! I approve!!!
How to make a simple set of ultrasonic transmitter and a seperate ultrasonic receiver to measure the medium density in between them
Decent beginner project for beginners who are beginning to just start out.
With a feeding mechanism you perhaps could create a 3d display which could add or remove arbitrary number of points? How many 3d levitation points can you form reliably?
I guess the display could have a "feature" of spitting at you when you remove points
Amazing work!!!!
too good to DIY
Ultrasonic hoverboard. Angled in just the right way to bounce creating a upwards force. Or at least that's my theory.
