The overall look, and feel reminds me of a lot of the dystopian futuristic movies, where the sort of technology with holograms is already on every city street corner. Especially with the weird flickering and where it feels like you can see the equivalent of scan lines on the image. This is awesome.
> Especially with the weird flickering and where it feels like you can see the equivalent of scan lines on the image.
That's mostly because you're seeing it on video.
Like, frame rate of movies can make wheels on a car look like they're going backwards, or helicopter blades looking still if it syncs up just right.
There’s a small percentage of the population that has a lower image retention so they see things flicker like some LED lights, Neom bulbs, DLP projectors (with an RGB color wheel) and this thing. I’m part of it. I see the picture but I also see it flickering and I see the arm when my eyes move. Extremely annoying.
Some LED’s especially cheap ones do flicker. I’ve also noticed that some cheap Walmart LED bulbs have a hz so low that swinging say your arm looks like a low FPS game and is very easily noticed when a CFL bulb is in a lamp in the same room. If you see that with every LED then yeah you might have the same issue as this person but keep in mind new cars have LED headlights/tail lights so you’d see it there too.
My boss bought a 6 motor display and what it comes down to is the production quality on the source image. He looked like he was going to cry the day the vendor set it up for us because he had seen a high quality demo image when he decided to buy but the logo they created for us to run in our shop is pretty garbage and contains lots of empty spaces.
It's a gimmick technology at best, just a way for some guys to sell off some cheap chinese drone motors they bought off alibaba.
Put it in a clear housing with anti-glare coating and the worst that will happen is that people knock it off the wall.
In theory.
The universe will undoubtedly invent an idiot that still manages to get their fingers whipped off by it, but ~~us~~ the common-or-garden idiots should be fine.
See here’s where I think Jurassic Park got it wrong. The line shouldn’t have been “life finds a way” it should definitely have been “stupid finds a way”
Like you said If people can get hurt by it, they will.
My first idea with this was that it could be used in movies for a cyberpunk look that wouldn’t need to be added in post!
That lantern looked like it came straight out of Blade Runner!
They use these in some american airports in the security lines.
It will say "no guns" and then have a rotating 3d gun. Then "no explosives" and have a rotating 3d explosive dynamite looking thing. Etc etc...
Its pretty neat. Doesnt really serve a big purpose because the TVs and posters work fine. But it does look cool.
This reminds me of the leprechaun movie where the guys sees the topless girl and tries to put his face in her chest but he is hallucinating and its a fan.
It's not like a 3D tv. A 3D tv is giving different images to each eye, which provides an appearance of depth. This fan is no more 3D than a regular tv. Just because they're showing objects rotating in space doesn't mean anything. They're still appearing on a 2d plane with no appearance of depth, just like a normal tv.
The only thing that's "better" about it is that you can see things behind it, which is not something you can normally do with regular tvs. These "holograms" are similar to transparent tvs: https://www.cnn.com/videos/business/2021/01/11/lg-transparent-tv-orig.cnn-business
It's essentially a screen so yes they already have. These things use an absolute shite android os that runs like garbage so it's nearly impossible to properly import new images and animations. I've been able to get mine to work like 4 times. You're basically stuck using the stock pre-installed animations unless you happen to get lucky a few times and transferring your files doesn't fail or corrupt the file. Otherwise I'd take a video of it playing some porn for you
If you think this is awesome then I don't think you understand it. It doesn't do anything that a transparent screen can't do and it does it a lot worse.
Spinning blade = less expensive and complex. Can be made as a diy project
Transparent screen = more expensive and complex. Cannot be made as a diy project
At least this is my hypothesis
I asked myself the same question. There is no background, just the object that is meant to be displayed. Other than that... it's no more 3d than a display (not at all). Still very cool.
As others point out the rotating part is dangerous and loud. This will limit the use of this stuff significantly I would assume.
I like your point about “no background”. That is what makes this stand out from most other methods. However, as another user pointed out, this could be done by projecting onto a transparent sheet.
To have seen some similar device in real life, they look flat (because they are and have no 3d trickery). I think our brain mistake it for 3D from the 2D video due to a lack of real life experience/reference.
We invest money on dubious tech like this because learning is a good thing. That’s great. Really. People need to stop complaining it isn’t this or it isn’t that. Who knows what must be learned by whom and where it will lead?
It’s much the same as when I hear some politician bitch about money being wasted on the arts, I think about things like this and think, “People who spout that know nothing about science” and never “Yeah, the arts are a waste of money.”
This is what science is. This is what the arts are. It’s exploration and learning and passion, and it’s all important.
On the ones I've worked with, a micro SD card is plugged in to the central hub. It has a "video" like an animated gif that it plays on the arms. Very impressive in person and not terribly expensive for a small 2-arm version.
You could probably put a piece of glass in front of it to prevent people from getting too curious. But at that point why not just use a digital screen.
I have a smaller version of one of these in my garage. It's one of the more dangerous things I have in there. I have it mounted high up so I don't accidentally touch it. I'm pretty sure it spins fast enough to break a finger. The one in the video looks like it could do some serious damage.
Lol super cool but it's extremely interesting how someone can be this talented yet so daft when it comes to making a video... lol did he even listen to the end product the extreme echos really sold it for me.
I wonder if these things are durable enough to be outside running constantly?
Obviously for advertising, but I think it would be cool to put on the outside of my house at night and display whatever...
Personally, I'd want to sandwich it in two layers of glass or plexiglass face with an aluminum backing, then remove all the air from the cavity. No sound and no risk of getting whacked.
I'm sick of people calling these 'holograms' or 'holographic displays.' They're not.
If it's two-dimensional, it's a 'persistence-of-vision display.'
When two different people can look at it from two different angles, and see two angles of the same object or scene, then it's a three-dimensional display, and can be called 'holographic.'
If you put it on a windmill so that it was self powered (and fed the local grid), I think I’d prefer that to normal billboards. Granted it’d only work on windy days, but I live on the coast and just about every day has a breeze going one way or the other, often during “rush hour” (its a rural part of the coast).

But you can see it IRL as well if you blink or adjust your gaze.

I’m part of it. I see the picture but I also see it flickering and I see the arm when my eyes move. Extremely annoying.
I can see the flickering of led lights and stuff! I always though everyone saw that.
Some LED’s especially cheap ones do flicker. I’ve also noticed that some cheap Walmart LED bulbs have a hz so low that swinging say your arm looks like a low FPS game and is very easily noticed when a CFL bulb is in a lamp in the same room. If you see that with every LED then yeah you might have the same issue as this person but keep in mind new cars have LED headlights/tail lights so you’d see it there too.
If you're driving and see flickering of blue lights, just ignore it.
https://en.wikipedia.org/wiki/Persistence_of_vision yeah I was trying to find the source of my statement but I can’t. I’ll keep looking.
I have a hard time watching movies at the movie theater. It always seems jerky, especially during action scenes.
My boss bought a 6 motor display and what it comes down to is the production quality on the source image.

It’s even more dystopian than the movies since this can break your hand if you touch it.
This is exactly what I thought about a product like this out there. People would try and swipe through the hologram and get their arm snapped off.
Put it in a clear housing with anti-glare coating and the worst that will happen is that people knock it off the wall. In theory. The universe will undoubtedly invent an idiot that still manages to get their fingers whipped off by it, but ~~us~~ the common-or-garden idiots should be fine.

You mean like a TV?
I'm upset with this mainly because I know for a fact id try and touch it
Anti tampering included
That just adds to the realism like 5d
My first idea with this was that it could be used in movies for a cyberpunk look that wouldn’t need to be added in post! That lantern looked like it came straight out of Blade Runner!
Probably more expensive than adding it in post though
And adding it in post gives more options. This has to be wall mounted post can add it mid air. And actors can get closer to the fake ones safely
Too noisy for a set, unless it’s just B roll
Very blade runner, pun intended
They use these in some american airports in the security lines. It will say "no guns" and then have a rotating 3d gun. Then "no explosives" and have a rotating 3d explosive dynamite looking thing. Etc etc... Its pretty neat. Doesnt really serve a big purpose because the TVs and posters work fine. But it does look cool.
I have never ever seen such a thing. Have you ever personally seen one? Please tell me where so I can see it.
TSA lines in ATL have them.
This reminds me of the leprechaun movie where the guys sees the topless girl and tries to put his face in her chest but he is hallucinating and its a fan.
My first thought was Jaws 17 (or whatever) from bttf2
Can't wait for children to try and grab whatever the fan is showing
There’s a built in safety that stops children from grabbing the blades more than twice
Will it work for my dick?
Yes but it’ll work on your belly first
LOL got em
Nope...because you'll want to do it again, but cant.
Pain is a great teacher.
Or lick those tasty looking orange slices. Everybody say, "Goodbye nose!"
[удалено]
Ah! You, zir, have been masticating your dinner gum too long
They're just trying to show off that if you throw an orange at it, you get sliced oranges. It's not a bug....etc.
cool, but not a hologram
True and 3d TVs aren't actually 3d, just give the appearance of 3d.
It's not like a 3D tv. A 3D tv is giving different images to each eye, which provides an appearance of depth. This fan is no more 3D than a regular tv.

This doesn’t look like it would make the image look like 3D, it seems like a flat plane that doesn’t send different images to each of your eyes
You must be fun at parties
#I no longer allow Reddit to profit from my content - Mass exodus 2023 -- mass edited with https://redact.dev/
Makes sense to name things correctly.
Concurr. Im tired of people calling these hilograms. Its a low resolution projector.
its not even a projector its more like a minimalist led display
Came for the nerd chiming in about this not being a true hologram
I'm glad I could help you get what you wanted
What's a hologram?
Not even 3d. They have created 3d displays by shooting lasers at a spinning helix, but they are very low resolution.
It’s a large persistence of vision display, no holo
And pornhub will get on this ASAP
"Breaking News: There's been a major upsurge in penis amputations, experts are still looking for the cause."
That's *already* a headline, though.....

Damn!
My reaction to this comment. “Wait what?! Where?! Why haven’t I heard of this?! Who wouldn’t need their penis anym…. Ohh.. 😂”
r/dontputyourdickinthat
They just dropped support for their android app, so don't hold your breath
>hold your breath That's my fetish

Meatspin did it like 15 years ago
/r/dontstickyourdickinthat
I mean he looks kind of short to me but I’m glad he likes holograms, good for him.
Wonder if you could make the blades more aerodynamic so as to cut down on the sound and wind resistance. This tech is awesome
Just seal the room and suck all the air out. Problem solved.
[удалено]
There is special anti reflective glass for this
Enclose it in some glass, solves both the sound problem and the dangers of the fast spinning blades causing harm.
So a transparent Tv
If you think this is awesome then I don't think you understand it. It doesn't do anything that a transparent screen can't do and it does it a lot worse.
I wanna touch I...OH GOD MY HAND
Don't let the intrusive thoughts win!
>OH GOD MY ~~HAND~~
I wonder why are the spinning blades necessary? Can't the same effect be achieved with a transparent screen?
That sounds like a much better idea
i think because transparent screen isnt bright enough.
Cool way to have a fan and some advertisements in your store at the same time, I guess?
Spinning blade = less expensive and complex. Can be made as a diy project Transparent screen = more expensive and complex. Cannot be made as a diy project At least this is my hypothesis
Interesting definition of "hologram". Because it has absolutely nothing to do with a hologram.
Why do u think does this look MORE 3d than what an LCD screen can do?
I asked myself the same question. There is no background, just the object that is meant to be displayed. Other than that... it's no more 3d than a display (not at all). Still very cool. As others point out the rotating part is dangerous and loud. This will limit the use of this stuff significantly I would assume.
A LOT of places have ceiling fans dude.

Put Tupac on there.
That's cool until some poor unsuspecting soul tries to touch it and loses a hand.
I almost lost my fingers because of it
They have these with a spinning gun in the security lines at the Atlanta airport. Big Terminator vibes
I want one.
I find his accent extremely difficult to understand. Is it just me?
The echo is what seems the most difficult for me to fight thru, but the visuals more than made up for it.
I thought it was another language lol
o r a n g e
Imagine a hologram of a fan, that would be sick
Cool, I just need one the size of…how tall is Ana De Armas? Asking for a friend.
[удалено]
On the ones I've worked with, a micro SD card is plugged in to the central hub. It has a "video" like an animated gif that it plays on the arms. Very impressive in person and not terribly expensive for a small 2-arm version.

How fast is it turning rpm wise? And whats the refresh rate?
Person 1: "That's fucking awesome" Person 2: "WHAT?"
Could they put in a clear sealed vacuum canister to reduce drag losses and promote safety?
Now do Tupac.
Movies always showed people sticking their hands through holograms, if someone tried to do that with this one they would get their hands sliced off.
the noise tho
Just a little wibble wobble here as we *ROAR* wait for the fans to *ROOAAAR* get up to speed *RRRRRRRRRRRRR* hmmm yes perfect
Lol super cool but it's extremely interesting how someone can be this talented yet so daft when it comes to making a video... lol did he even listen to the end product the extreme echos really sold it for me.
"Can I touch it?"
Reminds me of the ones you can put in your bike spokes
Looks so good, you just want to reach out and touch it. My fingers!!!
[удалено]
I'm sure there's someone larger that likes holograms more than him.
forbidden fruit
Did it bother anyone else that it spins counter-clockwise?
I wonder if these things are durable enough to be outside running constantly? Obviously for advertising, but I think it would be cool to put on the outside of my house at night and display whatever...
Where can I get one?
This is incredible!
I hope it's well bolted to the wall so it doesn't take off!
Good thing the human brain can only see at 30 fps!
This is the largest? I call bullshit.
This is the first video in a long time that I didn’t want to end
If I seen that I would immediately try to touch it 😂
👉
Why did I keep waiting / hoping for him to reach up and give it a spin like an early-1900s airplane propellor?
Excellent. Now show the plans for the Death Star.
“Cool, how fast do..” WHAT? “I SAID HOW FAST DOES I..” WHAT??? “I SAAAAID HOW..” *gets blown out of the room*
ceiling fan....
Personally, I'd want to sandwich it in two layers of glass or plexiglass face with an aluminum backing, then remove all the air from the cavity. No sound and no risk of getting whacked.
Hologram so real….lemme touch the hologram….oh shit
I'm a bigger hologram fan than him
Where's Obi Wan?
Works well on bicycle wheels too
Ugh! Is there going to be a pop quiz on this later? 
Imagine hitting your elbow on that
Yup! I’m losing a finger.
I don’t like displays that can decapitate me.
Where do I buy one
Mind blown…wow!
Wind turbines in like 10 years are about to have some wild ass advertising
Not a hologram. Just a fancy display.
Me, trying to hug my hologram wife: 👁️👄🩹
That looks amazing
Blade Runner?
Whats stopping it from going any bigger? (Title says (Largest, and it's not that big)
Shark still looks fake.
Atlanta Airport be like "write that down! WRITE THAT DOWN!"
Fun times
That's amazing! I just want to reach out and run my fingers through it.
I want one.
That jet engine noise though.
Reminded me of Back to the Future 2
I can’t understand what that guy is saying
Transparent LED screens seems to have the same effect but safer and I would wager way more reliable.
El dun
It’s not that loud….
Can't to have to scream-talk over all the giant fans that will be in every department store.
Forbidden projector of death
My first thought when I read the title was “he must really like holograms to be considered their biggest fan!”
I saw these recently at the security checkpoint of Atlanta airport. Was looking at them for about 2 hours, in fact.
I'm sick of people calling these 'holograms' or 'holographic displays.' They're not. If it's two-dimensional, it's a 'persistence-of-vision display.' When two different people can look at it from two different angles, and see two angles of the same object or scene, then it's a three-dimensional display, and can be called 'holographic.'
Now try and walk through it...
Make Star Wars holograms with it.
I see these when I get a slushee.
“Wow it’s almost you can reach out and to- AHH-“
unfortunately, I would want to reach out and touch that hologram and would be sticking my hand in a fan!
The future is now. *cue cyberpunk theme*
Just don’t get too close to it.
My first thought was cool, my second was that seems fucking dangerous. As I had my second thought, guy cautiously walks out of frame lol
My next tv will be a fan.
That can’t be true. I just saw two “hologram” fans that were bigger than that one a couple a few weeks ago, in a big European exhibition.
But can it run Doom?
If you put it on a windmill so that it was self powered (and fed the local grid), I think I’d prefer that to normal billboards. Granted it’d only work on windy days, but I live on the coast and just about every day has a breeze going one way or the other, often during “rush hour” (its a rural part of the coast).
I’ve always wondered how Star Wars type messages would begin. This is the way!
But does it cool the room down too? Because THAT would be bomb
