Theoretically you can double your pixel density by putting another LED panel behind the first facing the opposite direction with the pixels of the second panel being placed in between the pixels of the first LED panel. So when it spins the second panel can fill in the gaps of the first panel. This has quite the potential I must say.

Recommend the each row contain an odd count of pixel elements with the center row right on the primary spin axis. Or maybe even better, put an odd number of elements on one side of the board with an even number of elements on the backside. This could be two boards glued back to back of course. Bottom line is that as it spins, it would appear as if there were no gaps in the pixel density. (note that the even board's rows should also be slightly off from the odd number to make sure the horizontal gaps disappear along with the vertical gaps. BRILLIANT display. I love it!

I looked into this great idea, but unfortunately for this application its not super viable :( let's say you wanted your pov display to spin at 20 rps (20fps basically). These spi displays are usually 64x128. if you wanted reasonable pixel density, i would use the radial pixel count x π to find how many times per rotation you would need to update the display. In this case, the desired circumference resolution would be 201 screen refreshes per rotation (a refresh for each "pixel"). This resolution at 20 fps would require a screen framerate of around 4020 fps, and the theoretical max speed of these spi oleds is around 200fps at 8mhz. This math is for if the display was either offset or in landscape. If you centered the display vertical, you would only need 2000fps, but thats still unfortunately out of range:( I love the idea though!

Cool stuff. For balancing, Consider adding weight 'strips' to the left and right edges all the way to the top, pointing outwards to the led side. Or conside adding a metal arc. If you attach it from bottom left to top right, it might average out the amount of light blocking, making it invisible. Alternatively, it could end up with significant interference. Edit: the acrylic layer cover is a much better idea :) Maybe another idea: if you change the board color gradient from the centre to the outside, to reduce the difference in color of the board due to the local speed.

I think you might be able to use the backside, with offset diodes (between the front side), to create an interlaced so to speak resolution. ▒ So that the back side fills in the gaps between the diodes in the front side. Should also balance well. ♥ Edit: I wonder if a 2 boards in an X configuration would work? (double sided boards)

I love this idea and the fact you built a working prototype is really amazing! Thanks for sharing the results with us. I was thinking about the issue of the LED's disappearing when you are looking at the very edge of the PCB. Maybe an "L" shape (top view) would help? I suppose then it would be blank for half the rotation (which is worse). Maybe a double sided L shape or a one sided plus shape (like notch cutouts locking together)? My other pondering was that the square LED's are affected by perspective as they turn. I don't have any good ideas how to compensate for that with an image unfortunately. An LED would appear largest straight on and get less and less wide as it turns toward 90 degrees basically. It may be too difficult to change the brightness based on location of the pixel to match better (but it does seem like you enjoy a challenge).
@bryanbenting64155 ай бұрын
Very neat! For a relatively simple assembly it works surprisingly well. A double sided LED PCB with the LEDs offset on one side to double the density might be doable, though doesn't help with putting the LED die exactly on the plane of rotation.

For the leds being off center, you can try looking into alternative style LEDs that mount "reversed". They solder onto the "back" or the board, and shine thru a hole in it. I think they're sometimes referred to as "gull wing" leds

I had a similar idea but I'd spin a special semi transparent film that could still display projector light, something akin to holloween nets or a film I have not discovered yet. Then use dual projectors to project on to the spinning screen. The images projected when match the rpm of the screen, the projectors would be 90 degrees from one another for full time coverage.

Theoretically you can double your pixel density by putting another LED panel behind the first facing the opposite direction with the pixels of the second panel being placed in between the pixels of the first LED panel. So when it spins the second panel can fill in the gaps of the first panel. This has quite the potential I must say.
Think this would also add the effect of whatever angle you view the cube at, you would see the same result!

you could possibly balance out the offset of the leds in the rotation center by sandwiching the leds between their PCB and a bit of acrylic. That way, no weight is needed, but the leds are still easily visible. Amazing project :)
Cool..
Frosted acrylic might look great, to smooth together the pixels, if you want that.
@@rich1051414I was just going to say that, add a diffuser as a counter weight
Exactly, yes, perfect Comment Ideally with a Material with the same density should give the best balance and could also be used to protect the led s in between In a bigger version you could also drill out holes in between the led s to reduce atleast somewhat air resistance for better battery performance
Or use a double-sided board (preferably with slightly offset columns, so you get higher resolution).
Well done! I had a similar idea a few years back, but it was a lot bigger and it would just wobble out of control as soon as a turned it on so I gave up on it. I thought of using circular rails that wires from the spinning display would brush up against, but this design is so much better. Thanks for the inspiration!
I think using a higher pitch led matrix would be perfect for such an amazing concept, and I would love to see it more developed into a final product... love what you're doing and definetly you gained a new subscriber :D
I love the fact you use a proximity sensor(?) as a way to determine the frame timing. Seeing it follow your hand as it animates is so cool!
TCRT5000 IR sensor :)
Wow. I thought the sensor was more of a trigger. Didn't strike me it helps with frame timing!!
@@MrVijayMadhavan Yeah, probably used as a sync reference, because the DC motor doesn't seem to have any connections that would allow the microcontroller to know when it completes a full revolution, so instead it probably measures the intervals between something being close to the IR sensor to determine how long is one revolution and to have a reference.
@@hundredfireify yep! Seems so
I wonder if a Hall effect sensor could piggy back on the magnetic field of the motor. But I guess this IR sensor is a satisfying on-off switch too.
I love how you implemented the ability to rotate the image using that IR sensor, makes for a very cool result imo
Well, since everything is spinning and that sensor has a definite location, it would automatically rotate the image while using the right speed as a function of the sensor location.
Yeah, the sensor is required to calibrate the timing of the image display. Moving that calibration point therefore moves the image "by default"
This is incredible! I'd love to try making something similar. I love the use of an infrared proximity sensor as both a switch and feedback for the rotational speed, absolutely brilliant! Keep up the great work!
You’re the best man. I love everything electronic, circuit boards and their components and what you can do with them. I thought you led ear ring you made. That tiny flexible pcb and those tiny leds were so crazy cool
Adding a few degree tilt to the display should let you double the number of apparent rows that are swept through on each rotation, which might help improve the resolution 🤩
Smart! I would love to see this with a full colour, tilted transparent OLED on each side.
That might help with the balencing problem on centering the LEDs as well. Smart design.
This is the right of of comment section. Some great ideas in here!
Maybe even have another display on the back face and stagger the LEDs both horisontally and vertically.
For the dumb people in the back, are you saying tilt it like a box onto its corner, so that e.g. the leftmost pixel in a row spins higher than the rightmost pixel and it's like it's an extra row?
I quite like the "bonfire" effect over if it would be just a flame of a candle. But I suppose it might be worth trying to get that one done as well, for the practice at just getting better at programming and tweaking. This is super impressive. Imagine a set of 20 of these, lined up in a grid fashion, and flying on a drone. It's almost like a flying hologram(ish) moving picture sign!
Well, there is already some presentations using hundreds of drones and it is pretty much what you just described! Just search it up.
Yeah but the drones are not static, and they don't allow viewers to rotate the image, and the image density is severely restricted by the drone's bodies. Something like this we could probably scale up to 4k/8k image quality over time. We already have pretty high quality 2D spinning displays like this available on Amazon. By 90's standards this tech is already futuristic as hell.
@@bobriquardo5317 At first I thought even with one display like this over the body of the drone it still wouldn't be high resolution because the wings ocupy some space... but then I came to a conclusion, the wings are literally rotating motors!

Recommend the each row contain an odd count of pixel elements with the center row right on the primary spin axis. Or maybe even better, put an odd number of elements on one side of the board with an even number of elements on the backside. This could be two boards glued back to back of course. Bottom line is that as it spins, it would appear as if there were no gaps in the pixel density. (note that the even board's rows should also be slightly off from the odd number to make sure the horizontal gaps disappear along with the vertical gaps. BRILLIANT display. I love it!
Overall adding offsets to this would allow it to fill space much more fully. It's interesring how such a great thing still has the potential to get even better
Thats really clever! From making pixel art i see tge advantage of odd and even number of pixels/voxels but putting them back to back so they fill the gaps and eachothers weaknesses is so smart
Now im wondering if its possible to add color by having 3 sides with different color LEDs. Of course thatd require faster rotation and break your idea, but itd still be cool and interesting Also ruins the beautiful minimalism i think. But itis a direction this display could be taken in
No need to glue two boards, just have a double sided PCB made. Also being double sided guarantees alignment. He should also do RGB and as small as possible for maximum density.
@dougcox835 RGB ruins the minimalism but yeah Another thing thatd be interesting is doing 3 sided display with red green and blue LEDs on each side, i feel thatd be neat. Itd have a side effect of slowing down rotation being a way to animate color change
pretty genius, especially i like the part you did the starting process and 3D handling, well thought.
the added feature of being able to spin this a little with your finger tip is next level
I reckon you get a really high resolution hologram by basically doing this but using one of those SPI OLED displays (maybe a transparent one?) instead of the LED matrix board. Although you'd have to cover/paint it to make it yellow if you wanted it to look like a candle
I looked into this great idea, but unfortunately for this application its not super viable :( let's say you wanted your pov display to spin at 20 rps (20fps basically). These spi displays are usually 64x128. if you wanted reasonable pixel density, i would use the radial pixel count x π to find how many times per rotation you would need to update the display. In this case, the desired circumference resolution would be 201 screen refreshes per rotation (a refresh for each "pixel"). This resolution at 20 fps would require a screen framerate of around 4020 fps, and the theoretical max speed of these spi oleds is around 200fps at 8mhz. This math is for if the display was either offset or in landscape. If you centered the display vertical, you would only need 2000fps, but thats still unfortunately out of range:( I love the idea though!
A guy here on yt made a 3D volumetric display by stacking 10 of these slimer but longer oled displays they are $26 each and transparent it could work
I found a thing called Voxon, and it looks like it's already sophisticated volumetric display.

Does it detect or is he just adding friction that slows it down for a little bit and changes the orientation?
@@zrman96 The little rectangular bit on the side is an IR transceiver. When he puts his finger close to it, the receiver picks up the reflected IR light off his finger. Putting his finger on it wouldn't change the orientation, only the perceived framerate.
@@zrman96 I believe that it is detecting it but im not sure. There is an IR sensor on board thats probably for detecting how close your fingers are but idk if its used to detect the placement of your finger. Maybe he is only friction and im reading to much into it lmao but i didnt hear any sounds when he "touched" it so i assumed it was the IR sensor doing the work. Edit: look at 0:56 ! I actually thing the IR sensor is detecting the position! He's not touching it and the images followed his finger. Thats so cool
@@bluebaconjake405I'm guessing that the ir sensor is used so it knows when is has done a full rotation so it can stay still instead of turning if the speed is a hair off. By moving the thing the sensor detects (the finger) it changes where the display thinks forwards is.
@@masonbarber871yes, and that is the reason for the off-state if the finger is too far away: there's just no "frame" start reference (zero degree marker).

The technique is the same, they are both persistence of vision. The difference of course is that rotating the plane means led timing must be handled quite differently.
That's actually really cool. Also your voice is really engaging and soothing.
Hope to see updates on this design and maybe some simplified plans more novice DIY'ers. Such a cool concept
Cool stuff. For balancing, Consider adding weight 'strips' to the left and right edges all the way to the top, pointing outwards to the led side. Or conside adding a metal arc. If you attach it from bottom left to top right, it might average out the amount of light blocking, making it invisible. Alternatively, it could end up with significant interference. Edit: the acrylic layer cover is a much better idea :) Maybe another idea: if you change the board color gradient from the centre to the outside, to reduce the difference in color of the board due to the local speed.
For prototype I’d add 4 screws to the corners of led board. Rotating changes weight distribution, fine tune then fix with a drop of glue.
I can envision many possibilities including RGB LEDs more tightly packed together, or even a high res video display instead of LEDs. Very cool video!!

Love the design, honestly great work. It looks difficult to scale up, but I think an array of similar devices could produce some very unique effects.
Lovely. Appreciate your hard work.
I can't wait to see more about this project!!! I'd love to try to make something similar.
That is actually a very good prototype! The interaction built into it at such a tiny size is awesome, and I would love to see future designs with this, higher pixel density! I do wonder if you would be able to make a frame of enameled wire so it's porous? In doing so it would allow for faster and be less power hungry along with weight and air resistance, as well allowing the LED's to be viewable at both 180° and 0° (may end up leaving a trail destroying the illusion) Or even a see through PCB board but that's probably impractical Best of luck on your future endeavours!
or, and hear me out, seal the spinning mechanism in a tube with negative pleasure, or better yet, as close to a perfect vacuum as possible, if friction is the issue here. the only issue now would be to minimize internal refraction.
@@loremaster63 I cant believe the solution to high tech display was vacuum tubes all along. But imagine that, like a 8K display rotating at 120 rotations per second in a vacuum tube. Potentially two or eight of them sandwiched like a tree. You could get some insane games from that. Or perhaps cheat a little and use holographic reflective or projection displays for HUDs or special items. Project it straight on the glass, or in their own plane. It makes me wonder though what is more practical. Fiber optic and voxel based displays, since the biggest hurdle would be clarity and wire routing in the display. Versus rotational vectors, where the hurdle is rotation speed versus clarity.
This is amazing. I am no expert so discard my ideas if useless, but perhaps a clear circuit board to eliminate the black "fog", and a clear resin over the LEDs to act as the counterweight for the board after shifting it so that it can still be higher for balance? Getting that right would still be tricky, though. Also heat may become an issue if they are encapsulated. Really cool project! ❤
i wonder if a clear board and resin might transfer light much easier. you might have a full form image when spun with this method or it might just completely glow like with light throughout.
Would be really cool but glass PCBs are quite difficult and expensive to manufacture.
A clear board would expose the wiring, causing light to reflect off those wires unless the object were to be viewwed in dark lighting. This is a good train of thought, though, just needs more experimenting
@@HazelnutPi you can get transparent PET flex PCBs made quite easily they're just somewhat expensive and have some mounting related difficulties. The traces would likely be thin enough to not have a considerable effect though.
absolutely gorgeous mate, loved it
Fantastic work. How have I never seen this channel before? Wowza!!!
I might recommend having the LEDs be flat and reflected on a half-silvered mirror that's vertical, to mitigate the thing where the center of the volume obstructs voxels in the rear (creating an "opaque central column" illusion in the current version)
I'm trying to understand; where exactly would the half silvered mirror be?
Put the mirror where the leds are and put the leds flat on top of the pcb facing up at the spinning mirror
@@combomeltWouldn’t the mirror have to be at a 45° angle or be a zig zag shape and make the image “wobble”? Or am I missing something.
if i understand it right (and that's an ask) i think the mirror can be placed vertically where the led board is currently, the led grid being placed horizontally at the bottom facing upwards and the mirror's half silvering will create the 45 degree angle necessary to remove the columnar effect?@@lolithighs
youre right, i cant make it work in my head either!@@lolithighs
Nice! a rotary transformer is another option for coupling power, like they used in VCR head drums, though can get mechanically complicated combining it with the motor. I suspect balancing at the bottom may cause some imbalance about a tilted axis. Maybe a thin PCB with some heavy inductors/ferrite beads between the LEDs could balance it fully.
Similar approach would be to add a larger solderpad above/around the leds and put enough solder to balance it.
Seriously ... one of the coolest projects I've ever seen. Good Show Man! 10+
awesome job! what a prototype can't wait for the final version ;)
That is Awesome! I think you might be able to use the backside, with offset diodes (between the front side), to create an interlaced so to speak resolution. ▒ So that the back side fills in the gaps between the diodes in the front side. Should also balance well. ♥ Edit: I wonder if a 2 boards in an X configuration would work? (double sided boards)
Oh great we're going back to interlacing 😂
Ah great idea. I had just written my own comment about this, stating the same idea. Just to come to the comments and see that you beat me by a week. Would love to see more prototypes on this.
You can either put the lights offset and get an increased spatial resolution that's interlaced or put the lights in the same spots on the back and get an increased temporal resolution ie framerate
Lol. At least 3 of us are on the same page. Yes i would love to see him use the back side too. Btw you beat my comment by 1 day
You intelligent boys xx
I love projects like this! Great job! Can’t wait to see where it goes.
Bro! this is simply amazing! I'll following your work
Very cool. Amazing how well it works in a (relatively) simple form
I love this idea and the fact you built a working prototype is really amazing! Thanks for sharing the results with us. I was thinking about the issue of the LED's disappearing when you are looking at the very edge of the PCB. Maybe an "L" shape (top view) would help? I suppose then it would be blank for half the rotation (which is worse). Maybe a double sided L shape or a one sided plus shape (like notch cutouts locking together)? My other pondering was that the square LED's are affected by perspective as they turn. I don't have any good ideas how to compensate for that with an image unfortunately. An LED would appear largest straight on and get less and less wide as it turns toward 90 degrees basically. It may be too difficult to change the brightness based on location of the pixel to match better (but it does seem like you enjoy a challenge).
Very neat! For a relatively simple assembly it works surprisingly well. A double sided LED PCB with the LEDs offset on one side to double the density might be doable, though doesn't help with putting the LED die exactly on the plane of rotation.
I love how simple this design is and how well it works! I am inspired to get hacking a larger one would be fun, I wonder how big this could scale perhaps would eventually have to be a rotating mirror and optics due to mass/torque considerations very cool!
This is wonderful
That is pretty impressive! Especially how you can control image orientation with your finger and the IR sensor.
For the leds being off center, you can try looking into alternative style LEDs that mount "reversed". They solder onto the "back" or the board, and shine thru a hole in it. I think they're sometimes referred to as "gull wing" leds
I had a similar idea but I'd spin a special semi transparent film that could still display projector light, something akin to holloween nets or a film I have not discovered yet. Then use dual projectors to project on to the spinning screen. The images projected when match the rpm of the screen, the projectors would be 90 degrees from one another for full time coverage.
this is mind blowing! you have just created something people have been trying to make for years.
Subbed! Would love to see your progress on this beautiful device. In a world where people expect every new technology to feature some kind of “AI” it’s refreshing to see someone simply come up with a new practical physical concept.
Absolutely phenomenal - these are the sorts of creative endeavours that push technology to new frontiers. Massive thumbs up!
Incredible. Absolutely stunning engineering. Well done mate.
Very, very cool!! Thanks for showing!
I am absolutely captivated by this prototype, I would love to have something like this in the form of the bracelet to show off ideas or to analyze my 3D models in my free time.
Awesome! Having the LEDs randomly scattered on the board could help deal with the pixelated look. Although it will probably add complexity to programming the animations.
That is just awesome! I'm amazed at how well balanced everything appears to be. Wish there was a 10x check box for the Like button!
I'm genuinely impressed. I can't wait to see the next prototype.
very cool and interesting stuff ,as for centering the led's i suggest adding a clear layer over them that weighs the same as the board that is on the other side thus having the led's sandwithed between the two sheets and having a good centered mass.
This is incredible! Thank you so much for sharing and the writeup. Very detailed and interesting stuff! I can definitely see a future version using addressable LED matrix, something like the high density screens adafruit offers.
Such a lovely design. I would paint the back with the blackest most matte paint you can find. Some new black blacks are amazing. Get rid of that sheen on the back. Great work! I want one.
Saw this and immediately thought of decorative torch-like things that have an acrylic protective shield while they spin and play animations of things like fires outside a bar, or maybe even replace those big city map stands you find in big cities; Or project subway maps with a live feed of where each train is etc., etc. This is impressive.
If you could adjust the brightness of individual LEDs then you can create tonality and additionally gain the benefit of depth which in flame effects could be very realistic. The glow of the flame and then bright sparks or wisps of light. Also the use of RGB lighting could also add another layer of realism. I actually think this is a great concept and with some polish design could be a great product for candle-light like lamps. Very cool.
Wow, truly amazing work showcased in this video! Your approach to integrating technology and practical applications is impressive. I was wondering, have you considered incorporating an Inertial Measurement Unit (IMU) into your setup? The addition of an IMU could provide precise positional tracking, which would be particularly interesting when you're demonstrating the fluid dynamics inside the container.
the weight of the offset led mounting panel can be balanced by a clear panel in front of the leds... more ideal but harder to prototype would be a clear panel with leds and wiring embedded in a clear panel, possibly a poured resin that then picks up the leds and leads. in any case a several-way beautiful project :)) thank you for showing us.
very cool. bravo! looking forward to owning a volumetric mini campfire that I can set up in my space.
Very nice! I’ve long wanted to see a similar rotating volumetric display using a normal-sized computer monitor. Maybe with support for active-shutter 3D glasses too (though that would probably require support for user head tracking).
Imagine this with an lcd or better yet transparent display at a larger scale (might need to be in a vacuum for less resistance)
I was literally about to type this, how amazing this indeed!
Not sure you'd ever be able to get the update speed required for a decent rotational speed.
@@ferrumignis the question will be both how big and how fast you are spinning the display we have displays that can go up to 300+ hertz but the problem is cooling as they can make a lot of heat (although the spinning might help…)
@@ferrumignis I mean if you optimize it for airflow maybe right?
@@piman13_71 Can you really get tiny displays with a 300Hz refresh? I'm very interested, what interface do they use? (presumably SPI?) Could you point me in the direction of a manufacturer? The usual tiny LCD or OLED displays can't get anywhere near that.
You say it’s not high res but it’s genuinely amazing ESPECIALLY with how small and condensed the whole package is I think it’s sick tbh
Oh so cute. I love it! A little glass jar and wireless charger would be so fun to try!
to eliminate the central bar (the axe) that is too visible, you should have two system face to face and have leds on both side for brighter display. The display would be between the two axes. Great idea and realization you did, go on !!!
Damn, that's a neat display. Cyberpunk "Nixie Tubes", here we come! edit: finished the video, I see we had the same idea!
If on the middle an led could be on the very middle top of the display it would really add to the candle effect but the a hollow middle row or one slighter thicker cylinder below what I’ve suggested could also have LEDs all the way down to make the axis’s shape more active but I guess becoming thicker but shouldn’t mess with balance if centred well. May even improve stability. Great effort as usual and a wonderful prof of concept.
I love this. I'd love to see an increased resolution board. Even just double the LED count would make pretty clear imagery.
I worked as a theatre technician on the build of the set for “Phantom of the Opera” here in Australia, back in 1991. We developed an early 3X LED that had a sequence to look like a flame. The circuit was on a huge circuit board. We sent said board off to Japan and we received hundreds of microchips (10mmX10mm). Literally on of the best crews I’ve worked with.
some really simple animations might look great, like animating a ring up and down and changing its diameter. The resolution seems a bit low for things like "flame" or "rotating cube" but I bet some slightly simpler animations would look fantastic on it
Haha, low resolution for a "flame" or "rotating cube" as he proceeds to model sloshing liquid in a cylindrical container
@@gw6667 yeah I liked the fluid one too! I guess it's one big object moving so the detail doesn't matter as much compared to a flame where it's all about the details
This is brilliant. I'm ready to buy one to sit on my desk.
we can always rely on mit to make something amazing
This is super interesting, I would be curious to see what this would look like with an old cellphone screen or any small pixel based screen in the place of that LED array!
i cant wait for someone to run DOOM on this thing
I love it. It's so adorable. I'm obsessed with making miniature versions of ordinary things so this just lit up all the feels.
"lit up all the feels" said the millennial cringelord
@@endoflevelbossI'm 64 doofus.
@@BariumCobaltNitrog3n No, you're not. 64 year olds have feelings not "feels" you sausage.
I would love one of these that just does weird pixel dots. Like an old-day Futurist decor item.
