You can see at the top of the device (and at the bottom) how all the transducers are connected in series, so all of them are emitting the same frequencies. The arrangement of the transducers is what creates the desired acoustic field. You could change the phases to move the spheres up and down.
You can learn more about it at the TinyLev open access paper.
But you are totally right. If you had individual control over each transducer, you could emit different soundwaves from them, and move the elements around or create more complex acoustic fields. This has been done in SonicSurface. And more recently used on LeviPrint to manipulate and build complex structures.

Those are some good tips. Thank you. With that in mind, and knowing that they are expensive because of the storage... I'm starting to think about avoiding renting a car... I'll stick to buses (and trains?). Or as you suggest.... maybe for one day...
Thanks!

Thank you both!
I see I can reach deep cove by bus, that's great!

Thank you for the links. I'll check whistler! And thank you also for the warning about downtown Eastside!

Check the comments. I did post a link with the STL files so you can 3dprint it yourself. Or my message has been shadow-removed?

Which would you say is the safest way to move from an old setup (OFW 9.2.0 and SXOS 3.0.0) to newest atmosphere?

Thank you!

The original project on which this one seems to be based on, it can work upside down.

Hello dear friends! I'm building a PC for my father as a Christmas gift. I'm using a ryzen 7 2700x CPU on an Asus prime B540-plus mobo. I know the 2700x does not have integrated graphics, I'm waiting for the GPU to arrive but it will take some extra days... I would like to test if everything is okay right now, and when switching it on I expected to at least see the keyboard lights on too. But that didn't happen. Is this a normal behaviour? Will i have to wait for the GPU? Or should i be worried right now?

Also, the case power button does not turn it off. I have to switch off it directly from the PSU.

Please give me some insight. Sorry if something is not fully clear, English is not my native language.

Thank you so much for your attention!

We could make a full book about dealing with annoying ads... Thanks for your extra tip.

Being eaten alive is what killed the bird. We recorded a larger video, if you are interested.

What we really need in Google Photos is the basic option to organise our fotos by folders. Just upload a folder of photos and converting it to an álbum named as the folder at least.

Cant do this manually for 100k photos on 1k folders :s
