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.

@@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
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
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.
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
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!
@@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.
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.
One of the LEDs green channel seems to be failing at 8:37 in the upper left-ish corner, that's unfortunate. Sometimes the LEDs aren't soldered to the chip so well under the silicone...
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). 😋
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.
Physically very nice! The refresh rate gets too low off a single lead. 1200 is too many off one WS2812B data lead for a good refresh rate. I split my matrices into no larger than 16x32 and dedicate an ESP32 pin to each. You can run up to 8x1024 pixels at a full 30fps, but you likely only need to split your into two. And it's all code, except for one additional wire.
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)
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.
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.
@@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.
lol, should have put a stop on the end when punching at 1:30. It would have kept one axis automatically aligned and sped things up big time. Cool project! 4:00, the pros make it look so easy, don't they?
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
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.
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?
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.
I wanna build an LED wall too sometime soon but I really don’t know anything about Amp or Voltage drop calculations and so on... Any sites or so to learn this from or maybe even a pre made calculator?
Let's say one RGB LED can draw a maximum of 60mA (20mA per color) at 5V. So you basically have to multiply that with the amount of RGB LEDs you have. For 144 LEDs on a one meter strip you should get a supply rated for at least 144 * 0.06A = 8.64A. It will probably work with less though, as you won't ever use full brightness white on all of the LEDs simultaneously.
Maybe try putting a little wall between the ping pong balls out of aluminum or something to reflect light back into each "pixel" and cut out some of the light bleed to up contrast.
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)
I don't know why, but I watched video on phone around 1AM and still noticed missing hole just right at 1:35. Also I noticed that on the left top plate one LED acts weirdly - 8:36 for example. It's less visible on rainbow display later (8:45), but you can see how one LED doesn't match rest of panel, sixth from left, above your head. Also in first line fouth and eighteenth. Of course don't take this comment too seriously, I'm just nitpicking :) I totally *love what you make* and you are one of youtubers I really like to watch. I only wish to be as productive as you all guys on youtube are. Meanwhile in my two free weeks I wanted to tidy up room and garage, but I only made it worse D: And I never thought your intro music is much longer than those two seconds O.O
Awesome video as always, but it hurts me every time I see you printing directly on the heated bed on your prusa, why don't you print in a pei sheet? You will get so much better results!
#8:27 - da sind zwei Pixel fehlkontaktiert nett, spannend, wenn man das auf 240p skaliert, wie hoch ist das Delay ? ^^ (bzw. andersherum) Mario etc darauf könnte spannend sein ;)
It would probably have taken a lot less time if you had just used pegboard for the front and regular wood for the sides and back (if a back is even necessary). Since the LEDs are bright and the backboard is dark, any unfilled holes in the pegboard that don't line up would more than likely be unnoticeable as long as there is no light coming through them.
very successful I also want to do but I understood the reason of linking the tip in the lede connections but could not understand where the + tip connects help?

It’s so wholesome I love it
You are so true.

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!

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)

Imagine being a streamer and having this on your wall. Would be sick.

You could build a web app so that the community can control it somehow.

I love the happiness and enthusiasm in your videos, the joy after each successful step is contagious 🙂
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?

Superb work, what can I say but WOW!

Very very cool. And you wrote you own library for the ESP32 - even better :)
