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.
You can build one yourself using ESP32 open-source components, including a 1.3-inch TFT IPS display and a K9L glass optical prism. Powered by the versatile ESP32 Pico D4 microcontroller, the device supports precise motion tracking with an MPU6050 sensor. Easily programmed with Platform.io, this device opens up a wide range of interactive applications, from gaming to motion-based control systems. With endless customization possibilities, this tiny yet powerful display offers captivating new ways to experience immersive technology.

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

[@sujayxaradhya]

Where is that device? Can you share the link?

[@richms]

​@@sujayxaradhyait's in the description. But yeah $41 for the whole thing which makes this not worth it IMO.

[@muhammadshahyan8552]

What do you mean

[@ighor]

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

[@stefanopalmieri9201]

Sigh... yet another Pepper's ghost display.

[@DigitalMetal]

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.

[@ighor]

@@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.

[@IulianArcus]

Looking Glass's displays are true holographic on the horizontal axis.

[@prizegotti]

While you are correct, he does say "the illusion of a holographic 3D display" and "sort of holographic effect" throughout the video.

[@Sven_Dongle]

Theres a little more to a holographic reflex gunsight than a dot superimposed on a transparent background.

[@ClokworkGremlin]

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.

[@enilenis]

It's like an angled pass-through mirror in a teleprompter, only if it was encased in acrylic. Still cool though. Highly impractical, but cool to look at. It's a solution looking for a problem.

[@cesarguevara5144]

a 3d printed picatinny compatible housing with a stand alone battery would really make it interesting

[@nickz526]

Loving the Stellar tshirt

[@RickySupriyadi]

can we use this as display from pi4? like i mean streaming something 240 x 240 images/videos/app?

[@marka1025]

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?

[@retroelectrical]

Why does it have that annoying and very bright LED light on the front?

[@TimMessanger]

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

[@zclone]

yes i would love to see it bigger

[@JasonMitchellofcompsci]

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

[@NoSTs123]

The paradox of make. You buy stuff and put it together, program it ect. But you dont really make them do you.

[@jtjames79]

​@@NoSTs123 You need a dictionary.

[@gsestream]

very nice

[@StewartWhaley]

Anyone have a link to the microcontroller shown in the video?

[@jeffg4686]

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.

[@paulmichaelfreedman8334]

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.

[@markromine5103]

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?

[@StewartWhaley]

Agreed. I hope someone posts a link to this controller.

[@trevorgdn]

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?

[@theodricaethelfrith]

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.

[@Wilhuf1]

Needs to be made into a mobile holographic sight that points to the nearest good pizza shop.

[@ragv1954]

I see a great hologhraphic scope

[@armisis]

The aliexpress page has a batch of different ones the 12 dollar one is missing everything needed to run...

[@TheBadBone23]

Cool idea and video, but it's missing some accurate info..the price for example

[@danny_invadio]

Tell me the truth, did you use ChatGPT for your script? 🤨

[@coreyh3994]

So... have you seen Looking Glass displays?

Click bait aside, I built this exact same thing late last year and it makes for a nice desk toy.

[@bluegizmo1983]

Now make one with a 75 inch screen and prism 😂

[@davocc2405]

Could be interesting if you have two of them and they produce simulated eyes - with the 3D effect could be an interesting effect.

[@dshaw8356]

One step closer to the holodeck

[@enilenis]

Derek Zoolander: "A holodeck for ants?"

[@zenithquasar9623]

dude it is literally a pepper ghost

[@caryjulietate]

Possibly superimpose two video images. One night vision and one thermal from like a iseek iPhone camera.

[@user3001-]

But can it run doom?

[@PhocusJoe]

Mine can lol

[@galdakaMusic]

Would be great a HA voice Assitant based on this tecnology!!

[@kennj321]

max headroom, en.wikipedia.org/wiki/Max_Headroom

[@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.

[@rudypoo4370]

XLM - no hiding which crypto you like 😏

[@TheShorterboy]

so peppers ghost

[@Sven_Dongle]

You need a Bilibili UID?

[@settlece]

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

[@curtisnewton895]

it looks NOTHHING like 3D hologram, you never turn the cube, and we only see it up front

[@rch5395]

Ur voice sounds ai generated xd

[@dsan2910]

lol, benchy isn’t a high detailed print

[@MobTiesHub]

How much?👨🏾‍🔧🧬👽🧩🟣

[@muhammadshahyan8552]

SO IT'S NOT PLUG AND PLAY CRY 😭😭😭😭😭

[@thedevollsadvocate]

This guys voice is super annoying
