Ping Pong LED Wall v3

[@madhukeshnp]

My heart really broke when the things got broke.... but he still fixed it all over again.... a big thumbs up for the effort ...

[@DrZipZwan]

lucky the main panel feld with only 4 panels pugged into it....

[@bitluni]

also good the bottom row of cornerpieces didn't break. the 7 pieces carried the whole weight

[@RobertSzasz]

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.

[@RobertSzasz]

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)

[@ZsomborZsombibi]

Yep , "give up" does not seem to be present in his vocabulary.

[@Ryan-ob6gp]

+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.

[@greatscottlab]

His level of patience is too damn high.

[@Kai-Made]

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.

[@PCBWay]

It's not an easy work, but you made it. WOW~ Really love this amazing project :)

[@sdgelectronics]

Nice soldering. I particularly liked the bit where you soldered the floor 😭 Great project

[@ArponRoy]

Yea, Grate LED project I ever seen. But I like your "LED Clock Project" too and the PCB designing was very inspiring also.

[@RandomUser2401]

the wiring on the back though.. wow that is just messy as hell

[@Skeptic2006]

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!

[@oxenforde]

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]

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 🤣

[@honzapat]

@@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)

[@honzapat]

@@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.)

[@michaelm9871]

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.

[@drew6017]

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.

[@bitluni]

the corner pieces were more expensive... because of the dips. they cost like 30cents a part. but you could also use solder jumpers..

[@lucasimark7992]

Yes! Really surprised me too! I‘m really considering doing it as a fixed part of one of the walls of my lab.

[@BechirSeven]

Why didnt you make a soldring in the place of switches or the jumpers it will cost more less

[@royfocker19]

bitluni where do you think this could be available to purchase? Or do you plan to share PCB design?

[@FMSKremer]

@@royfocker19 also interested :)

[@Thuddster]

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!

[@TheAstronomyDude]

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.

[@tiporari]

By the balls? Sorry, couldn't help it.

[@StormBurnX]

20:50 he indeed just pulls them out by the balls

[@ServetEdu]

They sponsored the video so Bitluni might have gotten the PCBs for free.

[@bitluni]

they don't offer black nor these leds

[@bitluni]

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

[@bubgerkirg]

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!

[@juliannesermon8057]

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. ;-)

[@CEFG100]

Props to you for not only building this thing, but for having the courage to walk around bare foot on plywood

[@superslammer]

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.

[@chrisw1462]

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.

[@bobbeekrause179]

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! ^_^

[@justincastilloux8051]

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.

[@bitluni]

I was really sad that evening but it's the emotional rollercoaster is what makes us live

[@Senokone]

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.

[@Geo-Shi]

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 👍👍

[@raresmircea]

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.

[@johnsaunders6510]

That’s the most work intensive KZbin project I’ve seen. Amazing.

[@chriss2050]

[@Team974]

So will you be selling full kits ? I’d buy ready made panels that I just plug in and go for my shop easily.

[@GrizzlyHillman]

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!

[@ranger81de]

That's probably the most impressive project I have ever seen. These programming skills are absolutely incredible! Hats off!

[@rhr-p7w]

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!

[@TheHookUp]

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.

[@tookitogo]

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.

[@bitluni]

Mike Harrison also mentions to only use 50% to highly improve the livetime

[@uski]

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 !

[@2000freefuel]

no the parts are simply aging, it's the dirty secret of the industry nobody likes to talk about.

[@dougsteel7414]

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!

[@monyeko5263]

Any news on when you will let us have the PCB design so we can also have a good sir thank you very much for Uganda

[@CrimsonRegalia]

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.

[@AmadeusFromCH]

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.

[@suit1337]

and now do it with staggered lines to further improve density and brightness fantastic job

[@RobertSzasz]

[@yep.1106]

You're onto something that could be perfect for clubs here...

[@rickharriss]

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.

[@Tech-Random]

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

[@SegaJennesiss]

[@realyunggranny]

[@burnermaster5375]

I don't know how in all my years of KZbin 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.

[@mmpp0]

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?

[@DriZ01]

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.

[@HariWiguna]

[@coltonjames6653]

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.

[@aydintopcu]

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.

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?

I could imagine getting DIN Rail mounting cases for the Corner PCBs. DIN Rails are fairly cheap and come in different sizes, from 1 meter or less to how ever long the manufacturer can make them. DIN rails with standoffs exist as well, which could be useful for cable routing. Just clip the PCBs on, space them apart correctly, wire them and plug in your panels. That would make maintenance much easier as well. For the PCB DIN Rail mounts you could even get a manufacturer who can make them in one piece where you just clip the PCB in afterwards.

[@Harry11315]

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?

[@Ryan-ob6gp]

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

If you want a hole in the pingpong ball but youre not up to grinding them, just put them in a shallow acetone bath. They're made from nitrocellulose, which dissolves in acetone. You should also know that nitrocellulose is very flammable (its gunpowder), so you should probably incorporate some fire safety mechanism into this wall. Like its own dedicated sprinkler system. Any fire started in it will be ... explosive, to say the least.

Awesome Job !!! I got some free advise tho: Use Ruby Fluid flux on the solder joints and then afterwards remove flux and rosin residue with alcohol. Very Important to remove the residue because over time short circuits can grow across the rosin. I had to learn the hard way. Another thing is use solder with lead !!! Lead free solder is useless and does not bond well. Also maybe try melting a large hole in each ping pong ball with a soldering iron so that the LED modules sit inside each ball - it would be brighter and stronger. All the best on future projects !!!

Keep up the inspiring work. 👍
