DIY Ping Pong LED Wall v2.0
Вставка
- Опубліковано 9 лют 2025
- This version of my legendary Ping Pong LED Wall is 2x1,5m in size and consists of 1200 RGB LEDs. The build is done from aluminium using a DIY hole punch. This version is driven by an ESP32 and supports even camera streaming from an ESP32Cam or media streaming from the PC. More on that topic follows in a future update.

8:34 WTF? japan is at war? Rising sun war flag?
At this point I apologize to anyone upset or offended by the effect reminiscent of the rising sun flag. I was notified about the possibility that that would be associated with regimes in Asian countries. It wasn't my intention and it shouldn't even be associated with any military flag. I'm a pacifist and would alter it if I was aware of this before. en.wikipedia.org/wiki/Rising_Sun_Flag
@@bitluni dont be sorry. too many snowflakes these days. from an artistic standpoint, its a beautiful design. offend the offended
@크로아엔버
Well obviously. Isn't that the whole point of the video?
@@bitluni No worries, as a Japanese native I found nothing wrong with a fucking pinwheel.But, I don't go looking for trouble like some of these others do
You've got Swastikas all over Seoul and nobody cares.
I haven't heard so many "WOO!"s and "A-HA!"s since playing Mario64.
Well this was supposed to go on his previous video with the single panel, but it still applies.
He is like a Sim
It’s so wholesome I love it
You are so true.
If you are German and try to enterrain a english Fan Base you cant Go "Jaa ich hab's geschafft" because nobody will understand you
Imagine being a streamer and having this on your wall. Would be sick.
I'm!
ok
That's why I'm here ;)
You could build a web app so that the community can control it somehow.
Imagine him being a sgreamer and playing super mario
It would just be a stream full if wohoos and yehaaaaas
Next project : LED Wall v3. Full hd.
Yeah maybe with some smaller pingpong balls? and shorter distance between the leds?
@@gerben5964It was a joke.
@@derkernsen no of course not!!1!1! (but a simply even bigger Display with therby more pingpong balls would be really nice)
@@derkernsen Yes it can be seen as an joke, but creating fullhd is possible, and would be very nice!
i already made an interactive led wall you can check it out on my channel or search on youtube the name of the project is odycubes also you can play tetris on it with your hand movements
I was wondering why you didn't punch one of the holes in the first sheet. It bugged the heck out of me until you fixed it at 5:45.
Me too. Once I saw he painted it, I thought for sure he'd miss it until wiring in the LEDs.
Yes, we knew he'd have to catch it eventually.
Same here when he was fixing the sides, I alr noticed it
You saw it and you didn't tell him? You monster!
I Was looking for this comment
Seeing that LED Wall live was astonishing. Well done bitluni :)
That’s even more wicked than I expected it to be!!! Awesome work mate!
The pure joy when every work is done. (I know this is 2yrs ago but why would i skip this excellent creation?)
This is amazing. I ended up building the smaller 15x20 one from the last video this summer and it was so satisfying to see it work.
Hi, I'm also trying to build 15x20, do you Wall work with the camera images? What changes did you make in the code?
Why does this man have Mr. Bean level of excited noises when finishing any step?!
P.S. this project is awesome!
That's an insane amount of work!
For extra masochism, you could turn the ping pong balls into cubes with some heat and pressure or vacuum - then the pixels will be continuous!
I think I'd 3d print cubes before trying to reform a ping pong ball.
@@josiahdeal7493 Yeah, that would still take an awful long time though.
A plastic sheet diffuser with a grid of baffles to isolate the leds would probably be a lot easier to do.
Again your excitement when finishing the holes was so cute & your invention was so funny! Did you get an arm workout lol💪
Woah that's really cool. Ingenius to use the ping pong balls, really adds a cool effect. Imagine doing a full wall or ceiling like this. Even just white LEDs for general lighting would look really cool.
This is awesome. I want one of these to hang outside my house for Xmas.
OMG! Awesome! Great to see you get this matrix up and running! Great work!
"A grinder and paint makes me the welder I ain't" - AvE
Very very cool. And you wrote you own library for the ESP32 - even better :)
That punch is a nice bit of kit even if it looks a bit Heath Robinson...
You said it took 1 Hour...
300 in 1 Hour that's 5 a minute or 1 every 12 seconds...pretty good going if you ask me.
OMG! EPIC ^ EPIC
Well done Bitluni!
if you know someone who works in the engineering industry that uses a cnc turret punch it's always a bonus. When welding alloy always tac at the corners to avoid them key holeing
You're like a mad scientist in his lab creating monsters I love it ....keep up the good work !
Superb work, what can I say but WOW!
Full HD next! The size of a house! Awesome work.
one of the guests at MakerFaire was talking to me about making a version with 800 x 600 or at least 640 x 480 LEDs. I've put on my best "bitch please" face.. you'd need a 144kW power supply for that (granted in full white all pixels).
You've probably said that as a joke but it just reminded me of that guy. He had this "I can easily whip that up" smug mode on.. meh.
At 640x480, It would also be at least 19.2m (64 feet) tall, and have to be driven in 148 concurrent segments to maintain a frame rate of 24 frames/second (the max rate of the LEDs he's using allows about 50,000 pixel updates per second)
Amazing work as usual. I absolutely love the final result. 🤩
Might I suggest you switch from the ESP32 to a (ARM based) teensy since you can use this library called OctoWS2811 which can drive 8 strips on parallel. It can potential manage more than 200FPS in your 1200 LED frame. You will lose WiFi capabilities but that is easily added by putting a raspberry pi, which can get bitmaps over WiFi/Eth/local-storage and send bitmaps over USB to the teensy (at USB full-speed rate ~12Mbps). That library can even do multi-processor synchronization...
I am actually finishing up the same thing right now but I mine is much smaller and hexagonal (at 331 LEDs). 😋
I love the happiness and enthusiasm in your videos, the joy after each successful step is contagious 🙂
The best content on youtube. esp32 camera for a led wall is awesome.
8:22 👍
the next a cnc for the holes of the iron plates, congratulations... you are the best
Genius ideas!
AvE is on your welding skills chart. Thats great. ^_^
Awesome man. Have a great weekend, Andreas 🇸🇪
Pretty nice! You are so convinced from yourself. And sharing that makes other people try out something similar! Thanks for that 😁
A huge project, Luni! You might want to consider using an FPGA for your next LED matrix. It's a bit pain in the butt getting all 1200 leds wired but you will have literally zero lag while playing youtube on it.
Just amazing Bitluni!!! Amazing work!!!!
So cool project. I absolutely love it. Great video !!!!
I respect your patience, hats off 👌
This was the inspiration I needed to see for a project! Thank you!
I'm pleased to know that you are laughing during all the time you spend in your lab.
1:44 sound was awesome. i like it
Bravo, et quelle patience pour ce magnifique travail.
Dude, that’s frickin awesome...!!!
On the other hand, filming your welding are way above the other youtubers
Awesome build! Very well done and it looks amazing balls.
Cooles Projekt, gute Arbeit!
PLEASE GO BIGGER!!!!!
I just found your channel. I love your personality and your projects!! :)
Great video !
Nice build - Well done
war ja klar, dass Du jetzt video's drauf schauen und live camera footage uebertragen kannst :-) sehr cool!
Ich frage mich ob er deutscher weil er sich manchmal wie ein deutscher anhört
Awesome work!
I'm glad that my patron dollars create magic like this!!!
@bitluni's lab I would like to peak at the code for the ESP32 .. :) Also .. What is this library that produces these piebald animations? :)
In video it looks easy but i can understand how much effort it took to make it.
RESPECT.
awsome build
Sowas brauch ich für Daheim :O Klasse arbeit !
Is so
love the amount of wohoos and hahas on this video :D
Small thing, but really love using lever nuts as you did here! Nicely done.
This is really cool but is there any way to fix that lag when using video? Can HDMI be plugged into it directly? If so can you tell me how? haha.
I'm in the video again! wohho and I'm not passed out this time..thats progress!
didn't you scratch something?
Nice finally online :)
Sweet content as always. But hey man... you can buy perforated metal with nearly any size hole and spacing. Even staggeread which is great for hexagon patterns. Save ya some sweat and time.
Atomkey Sinclair, that kinda takes away the DIY aspect of it...
Sometimes you have more time available than money (and no doubt the pre-punched panels are more expensive).
Plus, it's more of a sense of accomplishment to have done as much as possible yourself.
you can also buy LED walls :P
Asshole.
@@wreckless_-jl6uu No doubt - it was just a thought for others that might want to construct a panel using another method. The pre-made stuff has the added quality of being very precise in the hole placement that might help in better alignment of the pongs. And you can also get it in material other than metal that would be cheaper than making it with metal and hand punched - plastics for instance. You could also use peg-board. You might have a little hole in-between the main fixture points, but it would be cheap and fast. 4X8 (foot) peg-board runs about $15 a sheet USD at the local hardware. Cheers.
Excellent. Love your work.
You better play bad apple on this boi
That’s like the testing video for anything with a display
thats amazing, now imagine if that hole you missed you discovered way later lol
Gratz man, great project!
I imagine him getting out of the bathroom and..."Woooohooo Haha...It's done!!!"...lol...
awesome job
Great Job!
Good going man!
There's a cool product available from Adafruit called a FadeCandy. It can control 512 WS8212 type LEDs, and connects to a PC via USB. You can connect multiple FadeCandys to one PC. It's then really easy to interact with them via a Processing sketch, especially to do things like play video, animated GIFs etc.
You look so happy :))
FANTASTIC!
peg board idea already drilled, I'm in the usa, you remind me of myself all my electronics, arduino background
Great work!
Is there a way to do this to DMX rather than the ESP32?
Glitch pixel at 6 column 9 raw?))
also at 16/1
we counted three when we were there, thankfully all in one panel
1,3 and 1,18 at 8:26 aswell
i seen it as well good eyes :)
Oh noes, there's a dead pixel! D:
Amazing job though. Well done! :D
Nice gaming monitor
Love your enthusiasm! :)
Thanks for the video
4:29 flip-flops and socks - it's so polish :D
Very nice👍👍👍
Very nice!
Ze Dschörmän accent is very strong in zis one. I like it.
you could use miniature ping pong balls to allow you to put them closer together helping you to get better resolutions by increasing the density of LEDs
3:40 Try tacking the corner and inside corners first before welding the beam. Since aluminum isn't that strong compared to steel, it melts faster. That's why you got that hole at the end. Hope that helps even though this video was a year ago lol.
Wow! Very Good.
incredible!!!
Impresionante! Muy bueno, como siempre!
Da gusto verte trabajar, el apaño de la goma simplemente genial. Deseando ver más. Gracias!!!!
Oof i saw that hole at the beginning and just kept hoping he would see it 😅 glad he did. It was bugging the shit out of me lol
You are crazy ! 🥴😉😱i like it !
8-bit music perfect fits to this video. love it!
Next a 1920 x 1080 ping pong ball array! XD
At 5cm pitch like this one, that would be 54m tall (180 feet for those of us in the US)
At the minimum 4cm pitch, that would be 43.2m tall (or 144 feet in the US)
That would be 2,073,600 LED's
I mean, that’s what a jumbotron is. A bunch of LED panels. This was meant to be a joke.
TIP:-
Squint and the 'Crappy' resolution becomes a lot better.
By the way...Great video, really enjoyed that.
I'd just take off my glasses.
1:50 Whooohooo Bitlunicoins!
Pretty neat, maybe dip the ping pong balls in black paint to cover the lower half of them, to provide more contrast, as it will reduce the light bleed?
For the punch you hook a 6mm 1m rod with a loop at the bottom on to the handle and use your foot.
Great job brother this is very impressive
This inspires me to learn aluminum tig welding even more! :)
very cool
As AVE says, "a grinder and paint makes me the welder I ain't"
Impressive job
Thanks for sharing 👍😀
