20 Years ago i made a 8x8x8 Blue LED Cube with two shoolfriends as a project in school. This was heavy soldering fun. I can imagine how much work a 16x16x16 Cube was! Very nice work!!!
Fantastic build! You truly created a beautiful work of art, engineering, and wizardry here. The extreme attention to detail and design of the process (like the LED jig for bending the leads) is inspiring! Keep it up!
Mirrors on the two back walls would add an interesting effect. What a project! I've downloaded your git repository, thanks for sharing. I'm headed down the rabbit hole!
YOU ARE WARRIOR . I have made the 8X8X8 simple led and i was about to die.... but this RGB16X16X16 is at least 15 times more complexe. You are crazy man ! Big kudos !!!
@@novaenricarter705that's a good point. It also makes me wonder if you could "optimize" this concept by pruning away LEDs on the innermost layers 🤔 you could potentially lessen that potential issue, and save a lot of work.
My wife asked why one would build this. My answer: just because it can! Hell of a job but I guess it must be quite pleasing and satisfying to build something this cool and make it to this level of perfection.
Man, all the animations are so cool! Great job. I would love to see an effect where it looks like the snake from Snake where it like chases an apple around in 3D space
painstakingly soldering 4096 rgbs and building all that is not an easy feat....mind blowing just, these are the people that deserve millions of subscribers.....
Wow, congratulations, very well done! I like the perfect alignment of the LEDs, because it makes crystallographic axies visible! (You have essentially a cubic crystal). Now I would imagine to use it for visualisation of scientific models, e.g. diffusion or atomic orbitals. For the latter one could demonstrate the dynamics as well, something that has never been demonstrated. Would like to have such a cube ...
I love my share of doing repetitive tasks while just vibing. But preparing 4096 LEDs? AND writing drivers for it? Good lord, I wouldn't do it if someone wasnt paying me for it. You are a man of Focus, Commitment and Sheer fucking WILL.
The amount of engineering and craftsmanship that went into this far exceeded my expectations upon first opening this video. This is incredible work and I seriously hope you're proud, you've earned the right to be. You cover mechanical design including material consideration and manufacturing methods, maintenance considerations in the form of modularity and critical system ease of access, electrical PCB prototyping, power distribution and intensive quantities of soldering, C++ Programming and then the patience of developing those animations. You've earned my respect and i strive to be like you.
It would be cool if there was an animation of someone dancing inside. I don't know how quality it would look on a 16×16×16 cube due to the density and general size but it would make for an interesting proof of concept for a larger scale "hologram" box with full 3D animations
Imagine this with high-resolution, like 500x500x500 or above, and realy small and transparent components. Imagine a game in that "screen". Awesome project, looking foward for future ones.
I’m used to seeing these being built with single-color LEDs, so I was blown away to see a multi-color led in a cube (and all the additional bends and connections)
Absolutely terrific. Saw this on Reddit and thought it might be a good project. However having just bought a soldering iron, maybe after I get a few more under my belt.
Thank you Dave! I’m a big fan of your channel. In the beginning i came there mostly for led related topics. But you can even make changing light bulbs or Windows topics interesting although i switched to mac years ago ;)
This feels like the early days of holographic technology. I'm just imagining this tech with much higher led density, with smaller leds and it would be an amazing 3D display. They went from small B&W tvs to 4K flatscreens, they could do similar progress with this.
Great thinking! That would be incredible. A "high resolution" human size display. Or even just a smaller cube as presented above. It would be interesting to see a "video" being played through the cube. A tree whooshing in the wind. Or even a tabletop "zoo"
i have seen some of these but nothing in this kind of quality holy shit that is stunning you got some nerves man keep up the good work maybe modular for diy and then sell the kit
Assuming those leds can show any color, I would think it wouldnt take a lot, to write some code that could downsample a video to 16x16 pixels, and then convert the colors of the bitmap to the leds. Then as you rapidly change each led to match the video, you could rotate the coordinates for each pixel, and literally see the video rotate along for example the Y-axis. Additionally, you could convert a text message that is shown in the pixel matrix.
If anyone is wondering how you can set the colour of each individual LED: It uses "addressable" LEDs. Each LED actually has a tiny chip inside. They have four legs: power, ground, data in, data out. The data is passed from one LED to the other, the first one takes its own value and passes the data on to the next LED which takes the next value and so on. I'm not sure on specific implementation but for example the data might look like this for three LEDs using [R, G, B] values where the first LED is to be set to red, the second green and the third blue. The first LED receives: [[255, 0, 0], [0, 255, 0], [0, 0, 255]], it takes its own value [255, 0, 0] which is red, and passes the rest [[0, 255,0], [0, 0, 255]] on to the second LED etc. There will also be a brightness value but I've ignored that for simplicity.
I believe that probably, due to response times, he is not using addressable LEDs, as handling such a large quantity could create a potentially visible delay. In his case, I am more convinced that he is using the following: "In the case of 4-pin RGB LEDs without an integrated controller, a common method to control them is by using a microcontroller and shift registers. A shift register is a digital circuit that can be used to expand the number of output pins of a microcontroller. It allows you to control multiple LEDs using a serial connection."
Boss, I'm gonna level with you, I didn't understand a single fucking thing in a technical sense. But sweet mother of Odin the process you took and the end result are fucking gorgeous. Stellar build
That looks amazing! It would be epic if it could create a 3D appearing image of a face that linked to an AI assistant like Gemini. It'd be like Cortana mixed with a futuristic verson of Wizard of Oz.
Should look into manufacturing and selling these, maybe at different scales. I could see a lot appeal for clubs/DJs, desk toys, game rooms, high-end christmas displays, etc.
This seems like something that could be mass produced by encasing the LEDs in clear plastic and having standard connectors so you can put as many together in any configuration you want.
Now, using a leap motion or similar, track your hand and display an approximated 3D model of it inside the cube that follows your movements in real time. Or use it to interact with the cube in any way actually
Fusion 360, 3D printing, PCB art, PCB design, even woodworking makes an appearance! You are a polymath creator. This is hands down the absolute best version of volumetric display I've seen made. And only 1.12K subs! What kind of pixels did you use? WS2801?
IDEA... if you find LEDs where the resin coating is as clear as possible then find the matching resin you could solidify the whole matrix into a block of clear resin therefore making the led resin casings invisible and you'd only have the visual impedance of the wires and diodes. Furthermore, I was thinking if you can find a resin that had the same refractive qualities of water it would theoretically be possible to make a water electrolyte and micro canals in said resin to make the wires invisible. Then you would only see some light refraction within the matrix block itself and the individual diodes... granted all this would require some new special equipment and manufacturing processes but holy crap... with small enough diodes you could theoretically achieve a very high fidelity translucent led matrix with very little visual obstructions. it would be a quality volumetric display.
Makes me wonder what it'd look like with reflective tint on the insides. Basically those infinity cubes/mirrors but with an addressable LED cube array.
Now connect it to Home Automation as a visualization of your voice assistant looking like a magical wisp, pulsating with each and every word they say. Truly magical
So you made a fully addressable 3D matrix of 16³ cube. That's a lot of work dude. 4096 LEDs, benches, tests, box, drawings and more drawings. My question is about the coding. I'm not good at math for coding . How do you do math to create image patterns plus RGB leds? Crazy coding!
Well first you need to think of something to display for example rain (i didn’t do rain) you can randomly or with some other random like generator create a rain drop and move them down a certain speed. I defined my cube as a 3D array -> cube[x][y][z] with colors. You can move the top row y=1 down to y=0 and then y=2 to y=1 for all 16 rows. If you want to do some math formula like z = sin(phase+sqrt(x^2+y^2)) you can simulate that in wolframalpha. Also i sometimes use coordinates from -1 to 1 for x,y and z and interpolate the colors if needed.
It did blow people away when trailer-sized ones were an attraction on plenty of Burning Man festivals. You could lie under one on your back and look up at all the "moving" lights.
i wonder if you could scale this to create a massive pillar that you can put atop of buildings/skyscrapers and create those beautiful 3d hologram ads/lightshows that we see in every cyberpunk depiction
Great project, that thing will look great forever and is a pretty cool platform to play around with different programming experiments. I bet you could get kids excited for arduino projects with this too

imagine preparing 262,144,000 individual LEDs by hand 😂
True but at that scale they may overlap and make any real depth unachievable. I wonder the limit on pixels before any depth loss
Ye lemme get 300 million leds
The problem is that it scales to the power of 3 instead of 2, so that’s already 100x more pixels than 4k

Would be awesome to see a 3d game running on that display. A very simple as Snake, Pong or Tetris.
will it refresh fast enough with basic components? Or do you need higher end components
You need addressable leds. The max refresh on them is 400hz. Basic is good.
Thats officially fooking awesome
Something like This has to be the future of television
This is pure art and electrical engineering -Outstanding!
3D snake would be sickkk. Btw, how do you design the pattern animations? Do you program them 1 LED at a time?
Imagine the further we advance in technology, and if led lights got as small as a grain of rice or sand
There could be "Hologram" animations!!!!!
