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!
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....
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
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.
I can't believe technology like this is so readily accessible through the efforts of people like you. Thanks
This is quite impressive, a lot of work and science here, nice job!
Bro idk why your channel isn't blowing up, the work you are doing is just superb and unique in the community.
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 amazing stuff! Thanks for putting this video together and making your research more accessible!!
That’s crazy… the power of modern FPGAs and the amount of free time is amazing….
This is wonderful educational content. Thank you for sharing your research and explaining each step so concisely.
Fantastic! Many would buy the finished product or a kit form.
I would demo for the five universities science programs in Kentucky!
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
Yawn. Any slower, and I'd have fallen asleep.
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.
@@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!
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.
@@kateward3914 im soo with you on this! shame we carnt get together and colaberate on doing these things! take care!
@@kateward3914
You guys are just too cool. First TinyLev and now this. Thanks
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. 😮
Your pronunciation of the word "FPGA" is amazing!
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!
I hate to be the "smart ass", but they're 2:56 not called shortcuts but short circuits, amazing video by the way
With an interest in clinical ultrasound of course comes an interest in phased arrray transducers. This is really intense. Subscribed !!
Dear God. You put everything on it by hand . .. . . Crazy.
Unbelievable! Have you experience in ANC systems? This project is terrific! Congratulations!
Great work making such a complex device, and making it this user friendly ( great voice too :] )
Wow, really amazing! Congratulations!
why are the advanced tutorials always the most informative?
Bc.. they contain more info bc they’re advanced..?
That's unreal mate!! Hat's off to your skill set!
really impressive, this channel must have 3M subscribers in any case you have an additional subscriber
Very generous to share all of this, thanks!
I had to watch your video twice. This is amazing stuff.
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.
Hello Sir, I am also working on my custom development board, on which software are you designing your PCB ?
Wow, that levitation was crazy!
This is how it should look.. Dont blink
Absolutely genius !!
Love it, from Montréal, Canada.
A big thanks for the algorithms
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!
Packing density could be increased with a non orthogonal layout.
Wow!! Very interesting topic and a very good video!
Wow. This is amazing. Also great presentation.
Love how you say "Effpighiaye" :-)
Wonderful presentation .. appreciate a lot of work has been for this video.
truly amazing, congrats for the amazing development !
Came here after “bitluni” ‘s video on phased arrays.
Open Source AESA HERE I COME! /j
Seriously though, this is a great project, and as you have shown it has many applications!
thank you for sharing! amazing work.
3k subscribers only?!!
It is amazing. I am interested in what you are doing here. I will go to check the published article.
Unbelievable work.
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.
Glad I have none of the gear required for this build or another project would suffer.
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 !
Great project! And funny the way you say FPGA :)
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.
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.
How to make a simple set of ultrasonic transmitter and a seperate ultrasonic receiver to measure the medium density in between them
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
@@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
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
I subscribed. That was really cool.
That was pretty cool ^^
Thank you
This Is insanely awesome
Amazing and commendable work.
Can the board levitate itself
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.
Probably did it this way because it makes the math easier
@@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 black market electronics
Wow. Just...wow!
now just how would i convince my employer that letting me build one of these is a good idea
Star trek level project I congratulate you
I wonder how a dog would react to one of those. It has to be freaking LOUD to them.
This!!! All day this!!! I approve!!!
Thanks for sharing! Can bass (=low audio frequencies) be created with this kind of directive audio and is it loud enough?
Can you add mini foam machine or smoke machine and some light to make 3d hologram? You deff can levitate foam bubbles, and it's much easier
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
Really amazing technology
impressive work
i liked that intro beat
I was waiting for basically the explanation of how the starlink antenna works.
Awesome!!! , thx u 4 sharing!
Thanks for sharing!
Can you make a video of a planetary simulation from 3D levitation?
And you made the first artificial gravity device when programmed with Linac Linear Accelerator type wave beats.
This is so sick!!
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).
That is very cool!
his voice is smooth
Nice video! Thanks!
A phase steerable tweeter for super wide sweet spot.
Охриненная штуковина. :)
Amazing work!!!!
Brilliant project. Nice job populating that pissy-bee. Oops, I mean PCB. hehee
Directed audio, very much on the lines of line arrays that use constructive interference
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?
I am extremely interested in this unit. Is there any chance that the kits can be provided assembled? More than happy to pay what is needed.
too good to DIY
Great stuff! Less than 200$!
I audibly Gagged when those capacitors had to be placed.
If you scaled the hell out of this, could you levitate a person? Or would it hurt them?
Круто!!!
good job, have an mathematics modelisation for that
Why do things in apps when your program can change the world around it? I love everything about your video. -Frank
Isto é bem impressionante. E se pudéssemos usar transdutores mais potentes?
Repeat after me... "G"
- Yee!
Okay, let's try one more time! :P
It's now that I realize that I like playing with the toys, not building them.
9 volts to 18 volt rail?
Impressive non ESD safety strategy there.😉. Nevertheless very interesting work.
Nifty AF !
Ultrasonic hoverboard. Angled in just the right way to bounce creating a upwards force. Or at least that's my theory.
