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 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 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.
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.
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
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.
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 🔫 💣 💥 🔫 🧨 🎇
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.
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.
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.
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?
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
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
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.
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.
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.
