Ping Pong LED Wall v3

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.

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

[Ryan-obgp]

+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!!

[dvastatr]

His level of patience is too damn high.

[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!

[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."

[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.

[juliannesermon]

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. ;-)

[michaelm]

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.

[drew]

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.

[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

[burnermaster]

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

[justincastilloux]

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.

[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. 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 🤘

[chrisw]

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.

[Skeptic]

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!

[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 👍👍

[dougsteel]

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!

[Nono-hkis]

Dude, this is a tremendous design achievement. Great job.
