Still watching, but I wonder if bracket could be soldered onto the back of each panel. With surface mount connectors you could have a full flat black front.
+1 for people who would love to see this made available as a kit. It seems like you've got 90% of the problems worked out and nearly a plug-and-play modular system ready to go. Awesome work. I'm doing some work for an arcade that this sort of thing would fit great with - pixel art etc.
I love how he even went through the annoyance of it tipping over and falling apart. Stuff like that happening makes lots of beginners give up. Just goes to show it can happen, and will happen, to people of all levels of experience. Always keep going!!
yup...it is really the bane of my existence. I mean, my impatience with things. The moment his wall came crashing down I would have torched the entire project and washed my hands...lol...glad he did not though this is freaking cool.
I can imagine the phone call to the toy supplier: "I need 2,000 ping pong balls." [Three days later] "I had a bit of an accident. I need 2,000 more ping pong balls."
@@bitluni How did you get all of that through clarence, sometimesi have problems with 10 small items, and you manage to sniff thru 2k?(Iam in CZ, but both countries go by the EU orders in that regard so I suspect its similiar)
@@QuantumFluxable At that point, atleast in my case, Iam better of buying it locally. (Not that 20% is much that would still be better, but all the extra they take for processing etc.)
your editing is very compelling! i feel like there’s lots of super interesting projects like this on youtube but few of them actually do it proper justice in the edit like this!
Totally awesome. I can't imagine how much work you condensed into a 21 minute video. Not to mention the work done on previous iterations to get to this point. Amazing.
Man i don’t think you get enough credit for the time you took to build this, film and coherently explain everything. This must have taken up a lot of your time. Thanks for that! Subbed.
I love it how you show the minor and major setbacks! Makes the build so much more relatable because when I build something I screw up all the time. ;-)
I made the panel using pretty thick mdf. It's way too heavy resulting into many broken wires and endless troubleshooting. Your new version looks so clean and lightweight. Good job!
99 out of 100 youtubers would have transformed that accident into the theme of the vid, with a totally dramatic title and a thumbnail with them holding their head and acting as if the Normandy landing has just failed. Your approach showed what your true goal is here. It’s rare to see people with an actual passion, instead of putting their activity in the service of clout and money 🤘
2:44 11kg of pcbs for $467 seems very reasonable. And how do you pull out a panel in the center? They look flush and I didn't notice any hooks or tabs.
between the panels are small gaps like 0.4mm to compensate for fabrication tolerances. i can slide a tool in-between to pull them out. I'm also able to push them out slightly from the back to get a grip. I used the power holes so far but I will cut away big chunks of the wood to reduce the weight for transportation and better access. i also have a tool made from a coat hanger that fits the mounting holes. pulling them out by the ping pongs is ok for presentation
Anyone willing to walk around a shop with dangerous stuff around in bare feet is insane. Its no wonder the damn display tipped over. If you dont have better shop safety than that, you also don't consider other aspect like the fact that the display is heavy and should be well supported. It's just plain ignorance.
Extremely nice.. great improvement over the last one. I would suggest a grid of light separators, like the one you used to glue on the ping pong balls, but thinner.. maybe thin black cardboard, and only as high as the center of the balls, or maybe a mm or two higher. It'll block the light that's seeping into adjacent balls, and make the image crisper.
I don't know how in all my years of RUclips searches for my own RGB madness that I missed your channel. I'm glad I came across it today. Great project here! I love it! I'm light years away from making something like this myself, but it is on my bucket list. Excellent work.
It's beautiful. When the panel fell over though...Im not sure I could have handled it! I'd probably have gone for a long walk, not come back for maybe a year or two. Started a new life in a different country. Had therapy, and finally come back to fix it. Respect!
I found your version one already awesome, now you can go into mass production :) Modularity is surely the way to go. Absolutely incredible upgrade you did there. The falling bit was heartbreaking, but good to see nothing got damaged beyond repair. Thumbs up man, looking forward meeting you next year at maker faire 👍👍
This just popped up in my recommended - my jaw was on the floor when the accident happened… kudos to you for working through it! The finished piece is immaculate, and it’s inspired me to keep going on my own projects! Definitely subbed now.
I'm interested to see how the white channel holds up. I've had some SK6812s in a ~20 hour duty cycle for about a year now and the white channel is noticeably dimmer on the "always white" pixels. I assume they are overheating, but not positive.
The Hook Up If they’re in waterproof LED strips with the clear rubber directly on the LEDs, I’ve had some of those age badly with the heat of the lit LEDs. Pulling off the clear rubber restored the brightness.
Both the phosphor AND the LED unfortunately have a limited lifetime. An interesting example is a router I had where only one Ethernet port was used for years. When connecting another Ethernet cable to another port, the difference in brightness in the two blue LEDs for each pot was totally significant and noticeable, the LED which has been on for years was almost 3-4 times dimmer !
I’ve always been impressed by your LED walls and even built my own take on my channel but this is insanely cool! I’ve been working on a PCB version for mine as well but it’s a little cost prohibitive right now. Maybe someday I’ll be popular enough to get big sponsorships like this
Big shout out to PCBWay, they have made multiple small runs of custom PCBs for prototype work, with mixed SMD and through-hole designs. Top-notch quality, fast turn, and at very surprising affordability. They absolutely rock!
I love this idea, though after working with professional LED walls for a few years, there are a few things that could make these more viable as a DIY prosumer product. If these were configured so that one "full-panel" consists of a 2x2 arrangement of the 8x8 "pong-panels", & a means of jumping power & data between the full-panels on the backside, this would be a very viable option for small traveling shows. That way the wall can travel small & more securely. Also, not a huge fan of gluing the balls directly on top of the LEDs but I see in your 3D printed attempt you made them open cavities which is better overall for both thermals, longevity of the LEDs, & light distribution. I would suggest adding one more component that you'd directly attach (screw into) to the pong-panels, some sort of socket that the open-faced pong balls could snap, click, or screw into, that way you eliminate the hot glue altogether (both during assembly & repairs). Not sure which method would be easier to fabricate though. Other than that, everything looks brilliant! ^_^
The design and coding was probably only 10% to 20% of the whole ordeal. Assembly and unexpected problems probably required the most effort. Speaking from experience working on my own projects; your patience is amazing.
And then there's me, that i can't figure out how to properly drive a 10x10 neopixel matrix... i cried when the panels fell.. i felt it in my heart. But i'm happy for the gorgeous result! Keep it up man
Cool project. What would it look like with a grid seperating the lights (like the one you used for placement) everywhere on the wall and a milky while plexiglass sheet on top?
That wall disaster hit me hard. 😵😵😵 Glad there wasn't anything broken for good. You have more patience than me. I would've just been like "forget it, I'm done"
Great project! You can probably avoid faulty led by setting the welding temperature lower. 400C is too much for components with plastic parts, it could also have an impact on the colors temperature.
Incredible project! I can see this being pretty awesome when used as lighting in a room! The fact that you can get VIDEO running on it is even better. Only thing I would worry about is how flammable ping pong balls are...be careful! Those things are CRAZY when they catch fire!
Amazing project. One of the most unique and well built things I've seen in a long time. Have you considered dividers to reduce color blending between pixels? Your ping-pong ball template printed in black to keep the aesthetic might work well and give you an even crisper image. Awesome work!
I died when the panel tipped over! I was very happy when you said nothing really bad happened to any of your equipment. I can't wait to see more of your videos, great job!!
If it was intended as a portable installation to be repeatedly put up and taken down for events and such, that would make sense. As a semi- permanent installation, I don't see a problem with the current connectors. The only thing I might add is some 3d printed supports to aid in alignment and relieve strain on the pins of the connectors.
A little suggestion for this great project; if you find a way to cut ping pong balls into two pieces properly, you would consume half of them and get more vibrant lights/colors because light will pass only one layer instead of two.
Really well done. You did a great job and the effect is excellent. I'm an LED light designer, and am really impressed with your work. Thanks for sharing!
I feel your pain when it fell .look on the bright side you never got injured ,that solder pot could have done a lot of damage to you .great work loved it.
That crash was devastating! I might have given up then, I'm so glad you persevered & made this cool light wall I'm interested if you'd consider making a triangle / hexagon grid one to compare with the square grid
Not sure if it'll make much difference if you're getting the factory to solder the pin headers, but a potential saving of effort would be to replace pin headers with pogo pins on the corner boards and pads on the led panels. Also not sure if it would be a cost saving or not. You would need less components overall, but the cost of pogo pins might outweigh the savings. Something to consider though? Also, perhaps epoxy the pingpong balls to each other instead of gluing to the board, and then use some sort of clip/velcro/doublesided tape/ mount to attach it to the board?
"the last ping pong ball. Or so I thought" Me: oh the glue probably fails on some. Drops wall Oh yeah that will do it haha. Seriously got lucky that nothing really broke
Great project! You can always change your diffuser-design to something square, which will make it easier to print. If this creates issues with the actual light diffusion I would suggest to create a convex layer inside the square. This might sound counter-intuitive, but the added thickness will let less light through. Using a square design will likely create brighter spots in the center of the squares, but it might even look good without a convex layer. Print the square with the open side facing up, which will allow you to print relatively fast compared to a globe shape.
Nice project , if you keep that placement helper glued to the panel you will get a sharper image because the color of the ping ball are influenced by the nearby LEDs .
Nice build. Suggestion. If you glue 16 ping pong balls together and rub them on a sheet of sand paper to make a hole the size of the LED's then they should fit neatly over the top without having to glue onto the LED's. In fact designing a cutter to cut the hole shouldn't be all that hard. perhaps a hot tube pushed through the ball. a jig of upright dowels will keep them spaced as you glue.
For awhile ive been wondering what it would be like to make a huge panel of rgbw leds, hundreds of thousands, then run fiber optic strands from each of the leds and condense them together like pixels, and line them up and glue them tightly, allowing you to make as pixel dense of a display as you want, given the diameter of the optic fibers you can source. Maybe this would be a cool project?
This sounds like a very inefficient and labor intensive way of making what would end up looking like a regular lcd screen, but with much less precisely controlled uniformity, and probably a lot of haloing around bright pixels
Just so you know, ping pong balls are EXTREMELY FLAMMABLE - you may want to reconsider using them in your home. Look up videos of ping pong balls on fire. NOT something to mess with!
you could totally have one of these in any art gallery with the camera mode being the main display. i think it would get pretty good reception in the art community
I know I'm very late (like Internet Explorer late) but you can use isopropyl alcohol to gently remove the hot glue, not heat or mechanical force required. What a beautiful project!
My heart really broke when the things got broke.... but he still fixed it all over again.... a big thumbs up for the effort ...
lucky the main panel feld with only 4 panels pugged into it....
also good the bottom row of cornerpieces didn't break. the 7 pieces carried the whole weight
Still watching, but I wonder if bracket could be soldered onto the back of each panel. With surface mount connectors you could have a full flat black front.
And I wonder if you could use a jig and drill or otherwise cut a circle in the ping-pong balls. (Melting might work too)
Yep , "give up" does not seem to be present in his vocabulary.
+1 for people who would love to see this made available as a kit. It seems like you've got 90% of the problems worked out and nearly a plug-and-play modular system ready to go. Awesome work. I'm doing some work for an arcade that this sort of thing would fit great with - pixel art etc.

For awhile ive been wondering what it would be like to make a huge panel of rgbw leds, hundreds of thousands, then run fiber optic strands from each of the leds and condense them together like pixels, and line them up and glue them tightly, allowing you to make as pixel dense of a display as you want, given the diameter of the optic fibers you can source. Maybe this would be a cool project?
This sounds like a very inefficient and labor intensive way of making what would end up looking like a regular lcd screen, but with much less precisely controlled uniformity, and probably a lot of haloing around bright pixels
Im very impressed this is like an actually LED panel you'd see in NY or Korea etc.. or anywhere you'd think they have big TVs outside
So, when are you getting insane enough to make a sphere version? :P
My favorite part....besides the project lol...is how giddy (happy) you get when you got your pcb's and when you hooked up the led panel.
i tried showing this to my brother, but then he started break dancing on the floor
I suppose you should use any type of the square partitions between the balls to prevent reflections from the nearest balls
2:47 - $467 for 30 boards + $150 assembly... okay...
for such HUGE pcbs!
Awesome project, props making it scalable and segmented. My fav was the changes to improve the framer ate. Well done
Just so you know, ping pong balls are EXTREMELY FLAMMABLE - you may want to reconsider using them in your home. Look up videos of ping pong balls on fire. NOT something to mess with!
If there is ever a v4, find between the rows and columns could help with the light bleed
you could totally have one of these in any art gallery with the camera mode being the main display. i think it would get pretty good reception in the art community
I know I'm very late (like Internet Explorer late) but you can use isopropyl alcohol to gently remove the hot glue, not heat or mechanical force required. What a beautiful project!
I think I might be binge watching all of your videos this weekend 😄
Not sure why RUclips recommended this to me, but this is excellent! Really awesome project and fantastically executed!
