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....

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.

спасибо. прекрасный проект и прекрасные ссылки. каждый день не перестаю удивляться на сколько же быстро развиваются технологии и как далеко ушел прогресс!!!

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.

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?

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 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!

i liked that intro beat

too good to DIY

Great project! And funny the way you say FPGA :)

Question: it it possible to create a sphere with a phase array like this to try to levitate the shere it self (or the power requirementes be to great)? and that happens if we use a concave array with this system? do we get more "levitation force"?

@UpnaLab

9 ай бұрын

only very small particles can be levitated using this system. A bowl array provides a better focus (stronger) but can be moved only within a smaller volume.

Great black market electronics

How do you do the audio aspect

Crazy guy :D amazing - really

his voice is smooth

Nifty AF !

Thanks for sharing! Can bass (=low audio frequencies) be created with this kind of directive audio and is it loud enough?

Nice - looks like pick and pray to me 😃 - where does the solder stencil come from?

wow! so cool! But how to improve the intensity of the ultrasonic?

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).

This is how it should look.. Dont blink

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.

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.
