Tiny Holo Cubic Display

I can't look away...

Discover the captivating world of tiny holo cubic displays that fit in the palm of your hand. Utilizing an exotic beam splitter, this high-resolution screen projects the illusion of a holographic 3D display against a transparent backdrop. The result is surreal, with crisp visuals appearing to float in space, creating a mesmerizing effect. In this video, I demonstrate its utility by creating an optical red dot sight and previewing intricate 3D printing models, showcasing recent advancements in tiny-pixel technology and extended reality displays.

It is not a "holographic 3D display" like you say. The image is still flat and not 3D, you should mention that.

US$13 gets you *just* the cube! if you want the actual device it is $48

[evanjrowley]

Red dot sight was my first thought. Thank you for time travelling and reading my mind.

[GeertDroid]

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.

It's the "peppers ghost" optical illusion, goes all the way back to the 1860s.

At one second you say you scrolled and found it. The next second you say "our project". So which is it?

Image a full sized computer screen (32" or larger) setup like this!

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 you want, you could try and make augmented glasses out of this.

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.

Great vid, love seeing this cheap stuff with high usability

I can see the future with hols. Imagine a small holo display on your ps7 controller or a a phone with holo display where u can see through some part of your phone

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

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?

We had big CRT's and flat tv's...now let's go back to big thick 3d holo tv's

[maurolimaok]

It remembers me of Star Trek Bridge Viewer.
Fantastic.

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

[TimMessanger]

any recommendations on how to make this Bigger?
I would like a tiny desk engineer

On 2D screen we could see the depth of this cubic display if you've show this as stereographic clip.

Hologram is a three-dimensional image where this screen is only 2D.
So its not a holographic display.
They could just create a transparent little screen and it won't have any difference .
