- เผยแพร่เมื่อ 18 มิ.ย. 2020
- This Ping Pong LED Wall is made of large PCBs sponsored by: PCBWay www.pcbway.com/?from=bitluni
It consists of 1920 ping pong balls as pixels and is controlled by an ESP32. The parallel data lines allow over 74fps and a camera live feed. The panels are easy to exchange in case of failure and built in bus lines and configurable mounting plates allow to build a display of any shape. My Arduino library provides the LED driver and a graphics interface to draw and display anything.

His level of patience is too damn high.
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.
What an insane project.....I love it :-)
I'm your fan!
and also, Bitluni's fan :D
Me too
Wow, you're here too! Btw, please make electronic basic about antenna?
You should try project like this.. I'm your fan.. :)
The legend has arrived
+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!!
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.
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."
it's so funny. my last walls already had impact on the aliexpress ai. it always suggests to buy ping pong balls when ordering ws2811 chains 🤣
@@bitlunislab 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)
@@honzapat you know you can just register your shipment with your local customs agency, right? it costs, but makes it 100% legal.
Only 1920 as I count it, so he already had some extras.
@@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.)
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.
I love how happy and excited you get over this project! sensing a lot of passion.
Keep going!
Nice soldering. I particularly liked the bit where you soldered the floor 😭 Great project
Yea, Grate LED project I ever seen. But I like your "LED Clock Project" too and the PCB designing was very inspiring also.
the wiring on the back though.. wow that is just messy as hell
Soul crushing accident. :( I was a bit surprised when you said "on the next day". I think I would have taken at least a day off! Very neat project.
I was really sad that evening but it's the emotional rollercoaster is what makes us live
I don't know how in all my years of TH-cam 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 not an easy work, but you made it. WOW~
Really love this amazing project :)
I love this so much. I’m surprised it was only $500 for the panels. I was expecting thousands when I first saw how many you got.
the corner pieces were more expensive... because of the dips. they cost like 30cents a part. but you could also use solder jumpers..
Yes! Really surprised me too! I‘m really considering doing it as a fixed part of one of the walls of my lab.
Why didnt you make a soldring in the place of switches or the jumpers it will cost more less
bitluni where do you think this could be available to purchase? Or do you plan to share PCB design?
@@royfocker19 also interested :)
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. ;-)
honestly the best part of the video was seeing you celebrate each success with the build, I felt the happiness with you
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.
monitor manufacturers: we can fit billions of pixels in a 20in space, maybe even less!
this guy: 4 take it or leave it.
loooool
That's probably the most impressive project I have ever seen. These programming skills are absolutely incredible! Hats off!
Amazed! I almost cried when the wall fell over, didn't you see it was going to happen? Your patience and skills are astonishing. Wow!
His genuine happiness when the panels worked is so contagious~
Dude, this is a tremendous design achievement. Great job.
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 👍👍
My soul hurt when the wall tipped over.
Awesome work! The new wall looks so clean.
This pingpong wall really keeps improving. Insane!
For the amount of effort put into this, it deserves way more attention!!
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.
Awesome project, props making it scalable and segmented. My fav was the changes to improve the framer ate. Well done
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.
That’s the most work intensive TH-cam project I’ve seen. Amazing.
check out project binky on youtube
You're onto something that could be perfect for clubs here...
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!!
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!
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.
By the balls? Sorry, couldn't help it.
20:50 he indeed just pulls them out by the balls
They sponsored the video so Bitluni might have gotten the PCBs for free.
they don't offer black nor these leds
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
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
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 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!
Man merkt es sofort, wenn ein Deutscher Englisch spricht :D
True :D
Man merkt es echt bei allen Kanälen
Is so!! Habe es auch direkt gemerkt
I wish I spoke german better. The best sentence I can make is an insult. :P
@@shythevans okay... can you speak german now?
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!
Great project. Very cool.
I’ve got to say my heart broke for you when the wall came down.
Man,
It's really emotional when we watch your amazing technical video!😢
Thanks for a such excellent video!
Simply amazing mate - I wonder how many of these will be appearing as part of everybody’s Christmas light show 😀
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! ^_^
V1 was great
V2 was fantastic
Now V3 is beyond imagination.
What a great job done.
I admire your skills, persistence, and dedication to continuous improvement.
I died insinide when the unspeakable happened..also you are a genuius madman, as much as I hate RGB lighting, I love this wall project.
This doesn't count as 'RGB lighting', this is an actual display.
Ok boomer
Question, why do you hate RGB lighting?
@@nutmeggaming11261 Because it's eye-wateringly garish, maybe?
@@nagualdesign just set it not to be? You have the freedom to do what you want with it, that's the beauty of it.
i find joy in your happiness with every success along the way. thank you for that.
Man, my heart broke when it crashed. Big props for getting back to it! Excellent work!
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!
WOW...WOW...WOW...WOW...WOW...WOW...WOW...WOW...WOW !!!
Very impressive Bitluni!
and you started all this ping pong thing 😄 @everyone go and watch Hari's ping pong matrix th-cam.com/video/Otk6VTVJKBU/w-d-xo.html
Thanks for the plug, Luni! You've taken ping pong LED *BEYOND* the next level! I think you need to claim your Guinness World Record!
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.
Great work with lots of patience. All the sub parts of your esp32 works are amazing. Congratulations.
The amount of work that went into this was so so impressive. I was sad when the wall fell.
So will you be selling full kits ?
I’d buy ready made panels that I just plug in and go for my shop easily.
wirklich erstaunlich! Good job!! :)
This channel is definitely my favorite. You make learning so much fun! Thanks for posting.
Only just happened across this. It was a joy to watch your enthusiasm (except when it fell over!)
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?
this is not something i expected to see today, aboslutly amazing! i am stunned of how good it ended up looking!
Do you have any more plans for this?
just stumbled on your channel and ended up binging on a lot of your vids, love the detail and humour. been a number of years since i messed with arduino and i was mainly using the nrf2401 back then.. it's amazing to see the features you get in boards such as the ESP32 nowadays and how cheap they are. definitely need to revisit some of my projects having watched your node red series. thanks for the vids.
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!
That looks really good! Next version, hold it with magnets and contact with pogo pins?
I guess this would me way more fragile and expensive
Why not pass the signal and electricity through the magnets? 😁
Magnets are so expensive.
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.
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.
Mike Harrison also mentions to only use 50% to highly improve the livetime
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 !
no the parts are simply aging, it's the dirty secret of the industry nobody likes to talk about.
Props to you for not only building this thing, but for having the courage to walk around bare foot on plywood
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.
What a really cool project. Totally love your videos !!!! I can't wait for v4 )))
8:32 Looks like you want get a job making floors for Eugene -Louis Rossmann’s favourite builder!
😂 "DON'T INTERRUPT ME EUGENE"
2:18 That's me if new LEGO is arrived in my home XD
This genuinely put a smile on my face multiple times during the video! Awesome job man. Well done!
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!
Your design is so cool and well-made. Are your PCB designs available anywhere for this project? Like on Patreon or something? Thanks.
So where can I buy the PCBs / Download the files for this ? :)
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.
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
What if the connector itself worked as switch as well?
"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
It would be beautiful to play retro games with these pannels. With "one pixel per ball" the games would be interesting to play.
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.
7:35 And the best is when you have hot glue on one hand and want to remove it with the other hand and burn it too 😂
Imagine his face when he realizes he can buy tv's
But a wall
bruh
woooooooosh
Not the same !
Looking forward to the updated led wall with connectors pre-assembled, would like to get one of these one day for my home.
Not sure why TH-cam recommended this to me, but this is excellent! Really awesome project and fantastically executed!
Me: Mom, can we have an 80 inch TV?
Mom: We have an 80 inch TV at home.
80 inch TV at home:
Is there a link where I can find the schematic for the boards? I want to build my own :)
I would kick some funds your way @bitluni to get schematics so I can order from @PCBWay !
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 🤘
Utterly Bonkers, Love it! your videos are clear, informative and exciting...great!
Can u share the files so we can buy them ourselves ?
I love this project
Did you get any response? I'd love to build this as well
Same, would love to build this
@@djjoeray Unfortunately no response yet from @bitluni about the ability to recreate this
check the description... it seems to have basically everything (check the github link for the software)
@@Nepheos What i didnt find so far are to PCB Layouts to upload to pcbway. Where can i find these ?
So, when are you getting insane enough to make a sphere version? :P
Absoluteky love the enthusiasm! Nice video, keep it up!
Wow amazing work! I really admire your perseverance and commitment, especially after that accident!
i tried showing this to my brother, but then he started break dancing on the floor
19:04 I´m pretty sure I didn´t clicked on a TOT video
Hey Bitluni,this project is the best of all the time
I think I might be binge watching all of your videos this weekend 😄
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
2:47 - $467 for 30 boards + $150 assembly... okay...
for such HUGE pcbs!
Would be awesome to see an updated version using the 3D printed ping pong balls at a smaller scale to allow you to put the LEDs even closer together!
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
Wow, richtig stark diese Wand! Cooler Typ diese Bitluni!
Great to see how your design has matured
You work is really impressive. Big LED wall is definitely on my list 👍🏼💯
there are so many thin led TVs these days that it does not justifies doing this project but A+ for all the work you did here
