Ping Pong LED Wall v3

Are you going to make available or sell your PCB designs?

I just found your project, I love it. I see in your git that there is no schematic. How did you wire the LED panels to the ESP32 ?? Thanks

Is this possible with much tighter spacing to get higher resolution?

Very cool!

This Project is still amazing! But now there is nothing left to improve on? What about a review? And also the Parts are not on your Tindie Store :(

I wanna see this used for 1080p 60hz gaming

Amazing!!

Too much side-bleed on the ping-pong balls. Maybe black out the bottom half of the balls. Also, instead of printing entire light diffusers, you could print grid that allows you to snap your ping-pongs in place. Press-fit ping-pongs would make repair much easier. Oh, and if you added hook-loop, or magnetic, or suction-cup, or whatever mounts to your corner PCBs (could easily be modular add-ons) then you could put these just about anywhere. Plus there's enough clearance (more with mounts) behind the panels that you could also print similarly attached cable routing jigs (conduit?), giving great flexibility in wiring and no holes required. An additional bonus of having easily moved corner PCBs would be in getting everything square, especially when using random surfaces.

can you buy simular segmented displays like these anywhere? Ive seen then in gaming markets, but cannot find them online.

You should try little transparent glass balls used by kids...

Nice!

Did you ever burned a ping pong Ball? Hope you keep in mind how dangerous they could be

Waiting for v4

But can you play Doom on it

Excellent! How has it aged these three+ years?

You know that would be a great idea for large lit billboards. Instead of building those giant screens or piecing many screens together. The pixelation from the ping-pong balls would merge at a distance. Another idea is those towers some cities have that have the lights that go all the way around and up/down. They have one in the city near where I live that does animations. It's like 10 stories tall.

Lovely project. The only problem I see is that the panels in each column depend on the ones before them, so for example if the first panel in the column brakes - the entire column will shut down. Not really sure how to fix that, but it must be not that hard with some kind of PWM expandors and little tweaks in the firmware. Anyway good job and good luck with this project!

Did you ever try to use PVC film instead of the Pingpong balls?

this was awesome

Hello , bitluni, I must say what
an awesome project..! have you tried using the display outdoors? how was the intensity?

So how can I get my hands on the PCB boards and whatnot? Like gerber files for all of the squares and connector PC boards?

The next video will have to wait, because of a massive RSI attack 💪

Man,
It's really emotional when we watch your amazing technical video!😢
Thanks for a such excellent video!

The ping pong balls are the weak link. The grid you used to place the balls would have been better with diffuser material mounted above. It would also get rid of the screen door effect. The bleed between ping pong balls is very high and distracting.

Nuts

megapixel= mega size pixel

Awesome! Love the way youre doing this all.

you sound like a kid on Christmas sir

why not cnc or just drill a hole in the balls? this way the light will only have to project though one lair or plastic and prevent placing them over the top of the plastic directly holes could also be drilled in the side creating ventilation

Why not print simple standoffs/glue-bases for the balls? Way less work, more reliability, bigger surface area.

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.

i still want this

impressive work!

Utterly Bonkers, Love it! your videos are clear, informative and exciting...great!

not gonna lie, I'd actually use that for gaming

So the parts list is a little silly considering the base this project is built on are custom PCB boards that viewers have no access to. Very cool project - but aint nobody out here able to do anything with it.

super cool! Respekt 🙌

honestly the most surprising thing is how ridiculously inefficient the first versions were tbh, this version seems obvious

Just so you know, ping pong balls are EXTREMELY FLAMMABLE - you may want to reconsider using them in your home. Look up videos of ping pong balls on fire. NOT something to mess with!

What if you cut the balls in half then glue them? Just a suggestion.
Well done, very impressive.

I think I might be binge watching all of your videos this weekend 😄

Your design is so cool and well-made. Are your PCB designs available anywhere for this project? Like on Patreon or something? Thanks.

that's some low quality idiocy... i hope yt never recommends me your channel again

See, even God hates seeing you working barefoot. Safety first, proper footwear in the shop.

Pretty cool 😎

It must be painful to clean dust from it.

It takes balls to make such a crazy project!

Absoluteky love the enthusiasm! Nice video, keep it up!

Could someone give me any directions how could I similarly stream an actual webcam image to a LED panel? Im using an RPi 4 alone. Thanks!
