Do you know of another type of holographic display? I mean real holographic display, not something from a movie. In the really world, this is what a hologram is.
@@DigitalMetal It is easy to Google and find holographic 3D displays, but those are not cheap. It is clear that the item in the video is a holographic 2D display, so the statement of the author is a lie. That was what my comment was about.
In your video you mentioned the device only cost $13 but that is only for the glass cube. The whole device will cost about 4x times that amount. I think you did that deliberately to keep the audience interested, thus way they will keep watching the video and you will be rewarded for that. So in my opinion this is LAME what you are doing here.
I can't find this specific board with that exact form factor, and the aliexpress link is just for the cube/lense. I'd rather not order one of the unreviewed listings without some additional info, as I really just want that board. Is that a "Wave esp32-pico-d4v2.2"? (Waveshare doesn't make that, and Google's practically useless rn.) Help?
It's a flat image hovering in 3D space; it's nothing new. It's effectively the "Pepper's Ghost" trick we've had as far back as the 1860s. The image itself has no 3D depth to it, unlike with stereoscopic glasses or a Nintendo 3DS.
I can build this with what I have right here. I bought a few of those 240x240 1.3 inch displays a while back. Just need to re-assemble my 3d-printer with the printhead upgrade. I use Pi Picos but adapting the code for it shouldn't be a problem.
Yeah, an infinite-focal reflector lens with a mini OLED or LCD under it is far more interesting and lets you do some really interesting things with the reticle. This thing is mostly just hype.
Yup, this thing would be completely useless for a gun, unless maybe you paired two of them, but then you'd just have created some really overengineered and very fragile iron sights.
This is not 3D, its just flat. I would like a truly 3D display as it will allow me to visualize 3D graphs (perhaps in Desmos) without only looking at a 2D projection and using mouse to rotate it.
This cube wouldn't work as a red dot sight. Red dot sights have a concave lens (negative meniscus?) that reflects rays of light that aligns the dot with the point of aim, regardless of the position of the shooters eye. It allows for faster target acquisition. Having a computer system like this on weapon sight would be handy and super cool, but it would require a more complex lens design.
If it was like a 4 inch by 4 inch cube I would consider getting one. The 1 inch by 1 inch just doesn't do it for me, way too small to really be useful.
To work properly it would need to be collimated. The point of a proper red dot sight is that it contains a collimating lens which makes the image appear at infinity, so it cancels out any parallax from moving your eye slightly off axis; this does not do that. The image appears near the back face of the cube. You could add another element if you could find a lens of the right focal length, but it would make the assembly much deeper and / or magnify the apparent size of the image to the point that you would lose usable resolution at the edges. I don't play with guns but I do have a red dot on one of my astro scopes.
0:51 I noticed that the first official item that was actually released by Google. It was very unpopular, but pretty interesting that has this type of technology is Google glass it’s the first and only publicly release glasses made by Google that actually has this type of display and an early one nonetheless
This contains a beamsplitter, which passes some% of the light and reflects some% back at your eyes, allowing you to see the image superimposed over whatever you have behind the beamsplitter. A normal prism is just going to show you a 100%± reflection of the screen with no superimposition.
No it wouldn't... this doesn't even come close to any kind of holographic or red dot optic. It's just a flat picture in space. The whole 3d aspect, of projecting a red dot into the distance, is lost.
@@brei2670 you are missing the point, is not for it to be used as a reticle, rather to look like one and be mounted in picatinny. Your brain only thinks in pew pew. The are more uses like in eletronic warfare, this could be mounted in a an modular antenna system using this as a display interface. The red dot like casing would just be for it to look cohesive. Go shoot cans now…
@@cesarguevara5144You need a display interface, mount a little touchscreen... What's the point of it being transparent? It'll likely be a nightmare to read in sunlight.
I tried the screen and raspberry on my pi 4 and bricked it do you have a tutorial on the pi 5 screen and loading doom or other software and apps on screens or resources
This is super shifty and should be disclosed as an ad and made clear that this is your own product. Real bad look and as cool as the device seems, I just can't trust you at all since youve lied and misled from the first word
To be fair, I don't think any of the links are his; he's just posting links to the parts he used to build it so that you can build your own. You make it sound as if he's building and selling these himself and trying to conceal that. The only 'lies' I can see is calling this 'holographic' and implying that using this as a red dot sight would be useful. I mean, no doubt those are amazon affiliate links but that doesn't seem beyond the pale.
i dont think you payed for it or you would know when you got to the checkout its not US$13 or if you did not notice you would of got just a cube in the post
OK besides all the corrections this is awesome and the direction technology is going that if rounded and turned into a wrist or for arm wearable would be awesomeness flick your wrist to control it have voice activation stuff too have web browsing it would be bitchen
(presumably) Americans are funny. Presents new kind of display that has (his words) endless possibilities and what does he choose for a personal, interesting demonstration of these capabilities? A gun sight. 🤠 yeeeehaaaaa 🔫 💣 💥 🔫 🧨 🎇
the prisim display was always known about but the lenses and the screens were not up to the corect quality as you see here we are diplaying simple images but in fact very complex data can be shown ( reality can be changed fully ! ( they did not want to relase this ) hence when google glass came out they blocked it super quick ! to day we are implementing the augmented reality and the miniture screens are comming available : So the old CD Trick with your mobile phone to display a hologram is not eneeded but this works on the same principle ! So In fact we have AI glasses now ! Bluetooth ! So we could now pass audio visionnn and a voice actuvated sytem controller to the system : hence we only need a python backbone operatig system to make a drivers to connect to these devices handle sound and vision as well as camera ! We thought that the interfearence would indeed be a problem but the enhancement is nothing after a while and to be withou them seems strange ! Sp weare gettign towards an open sourced areana in nwhichthe regular folk of the owrld can become creative and devlop peornsalized produce : even the glasses ! SO the race should be on to create the blue tooth glasses first , simple audio input and output and visal input and output ~! ( ie a remote controller and use this controller ( without CPU !) only a remote device ( for safty ) .. but in truth we have seen the reuction inn size of the mobile phone and even chipless phones ( MONITORED LINES < UNDER GOV CONTROL !) .... so we are in a direction !
does it: a) have a camera b) have a microphone c) connect to your computer (usb or wireless or other)? At that price, I know it's at least one of those.
US$13 gets you *just* the cube! if you want the actual device it is $48
Where is that device? Can you share the link?
@@sujayxaradhyait's in the description. But yeah $41 for the whole thing which makes this not worth it IMO.
What do you mean
i like how he doesnt say that in the video. Kinda makes it seem like he's apart of the scam
You only need the cube. Shove it on any lcd. It's an old gimmick.
It is not a "holographic 3D display" like you say. The image is still flat and not 3D, you should mention that.
Sigh... yet another Pepper's ghost display.
Do you know of another type of holographic display? I mean real holographic display, not something from a movie. In the really world, this is what a hologram is.

Looking Glass's displays are true holographic on the horizontal axis.
While you are correct, he does say "the illusion of a holographic 3D display" and "sort of holographic effect" throughout the video.
In your video you mentioned the device only cost $13 but that is only for the glass cube.
The whole device will cost about 4x times that amount.
I think you did that deliberately to keep the audience interested, thus way they will keep watching the video and you will be rewarded for that.
So in my opinion this is LAME what you are doing here.
Great vid, love seeing this cheap stuff with high usability
It's the "peppers ghost" optical illusion, goes all the way back to the 1860s.
You could make a tv as thick as an old tube tv, have a Grid of pixels in an thick matrix, that could create a 3d display
At one second you say you scrolled and found it. The next second you say "our project". So which is it?
The paradox of make.
You buy stuff and put it together, program it ect. But you dont really make them do you.
@@NoSTs123 You need a dictionary.
he found a little glass cube with a beam splitter in it, and then he put it together with a bunch of other stuff to make a display.
any recommendations on how to make this Bigger?
I would like a tiny desk engineer
yes i would love to see it bigger
I can't find this specific board with that exact form factor, and the aliexpress link is just for the cube/lense.

Agreed. I hope someone posts a link to this controller.
On 2D screen we could see the depth of this cubic display if you've show this as stereographic clip.
It's a flat image hovering in 3D space; it's nothing new. It's effectively the "Pepper's Ghost" trick we've had as far back as the 1860s. The image itself has no 3D depth to it, unlike with stereoscopic glasses or a Nintendo 3DS.

This is a thing since the sixties.
Needs to be made into a mobile holographic sight that points to the nearest good pizza shop.
so basically the cube itself does not have a display but uses peppers ghost technique for the hologram effect?
Theres a little more to a holographic reflex gunsight than a dot superimposed on a transparent background.
Yeah, an infinite-focal reflector lens with a mini OLED or LCD under it is far more interesting and lets you do some really interesting things with the reticle. This thing is mostly just hype.
Yup, this thing would be completely useless for a gun, unless maybe you paired two of them, but then you'd just have created some really overengineered and very fragile iron sights.

We had big CRT's and flat tv's...now let's go back to big thick 3d holo tv's
Can you get the ESP32 pcb and the screen (without any PCB attached, just the SPI) separately or did you just buy the whole AliExpress kit?
the link yoiu sent to ali express is all 1 stars... ALL 1 stars
Could be interesting if you have two of them and they produce simulated eyes - with the 3D effect could be an interesting effect.
can we use this as display from pi4? like i mean streaming something 240 x 240 images/videos/app?
Cool idea and video, but it's missing some accurate info..the price for example
is their thinner cubes? like would it wor with a sheet?
Loving the Stellar tshirt
So... have you seen Looking Glass displays?
If it was like a 4 inch by 4 inch cube I would consider getting one. The 1 inch by 1 inch just doesn't do it for me, way too small to really be useful.
This would be perfect to mount on a rifle as a "smart" red dot optic.

It was very unpopular, but pretty interesting that has this type of technology is Google glass it’s the first and only publicly release glasses made by Google that actually has this type of display and an early one nonetheless
Now the screen that the Google glass use is a rectangular glass prism, but still considered as a beam splitter
What makes the cube special? Can it be any "prism cube" or are there special properties it needs. I found a 2" Dichroic prism cube, would that work?
This contains a beamsplitter, which passes some% of the light and reflects some% back at your eyes, allowing you to see the image superimposed over whatever you have behind the beamsplitter. A normal prism is just going to show you a 100%± reflection of the screen with no superimposition.
Anyone have a link to the microcontroller shown in the video?
I wanna know too
a 3d printed picatinny compatible housing with a stand alone battery would really make it interesting
No it wouldn't... this doesn't even come close to any kind of holographic or red dot optic. It's just a flat picture in space. The whole 3d aspect, of projecting a red dot into the distance, is lost.

It’s a HUD for FPV flight
Just be straightforward! Whilst you are at it, this display would slap as a piece of jewelry! Wearing a photo album of loved ones as a necklace.
tupac's hologram was peppers ghost, tech from the 1860s. wtf are you talking about dude
Click bait aside, I built this exact same thing late last year and it makes for a nice desk toy.
i feel like we're one step closer to the spy kids hologram watch
this is cool but the resolution makes me sad, they make tiny 720x1280 1.5/2/3 inch displays, you didnt even get 320x240
