Screen share ANYTHING to this matrix! (Pi Pico)

[@reddcube]

Could you 3D print direct on to a diffusion firm, and just skip the first layer.

[@bitluni]

this is genius! will try and upload result

[@lostname1781]

Or maybe switch filaments between first and second layer. Transparent or grey for the first layer, and Black for the walls.

[@uranoxyd]

I feel like this should run "the game of life" code, auto resetting on some basic conditions. Super cool board

The WLED firmware for ESP(8266|32) has a Game Of Life prebuilt effect.

I HAD to stop the vid at 0:18, because in the starting teaser I have seen something I had not in years, and that bring very good memories… The Farbrausch "Masagin" Nvision 08 Invitation demo !!!!! DAMN I LOVE THIS ONE !!!!! THANK YOU TO BRING BACK THOSE MEMORIES !!!!!

[@Anticitizen666]

I made a tile wall with custom 16x16 neopixels each, running from an ESP32. I wrote a windows app so it would stream a region of my desktop over UDP to the wall (I only had 15 tiles to start with) and it ran great over WiFi at 60fps 😁 Yourube videos look great on it. Takes a LOT of power though. Obviously in c/c++

[@LunesPeltier]

Hello, I have a similar project that I am working on. Could we exchange on the C/C++ solutions you found?

[@FanofWebsCTO]

I would like to understand what you have done also!

[@ihmSelbst]

I build this with wled and send a json to update.

[@azpcox]

Pretty sure we got Rick Rolled in low res. :). Really cool expandable project!!!

[@patrickmcguinness3095]

It's funny that when I see the thumbnail on my feed I know it's one of your videos. Thanks super useful!

[@BRUXXUS]

I've had an LED matrix lying around for a a while now but haven't played with it. Maybe this will give me the inspiration to finally make something with it!

[@multiplysixbynine]

Nifty. I just made a hexagonal matrix of LEDs with triangular cells using 3D printed parts and acrylic. The LEDs are teeny tiny 1515 SMD components so it’s quite compact.

[@OMGWTFBBQSHEEP]

Sounds nice, shouldve put up a video of it!

[@arxaaron]

Nicely done. Great project and easy to follow, precisely explained tutorial on how to do it. Thank you for the resources! I'll be doing this one soon! Icing on the cake was the display testing with J.R. Bob Dobbs & Boing Ball graphics. Huge seal of approval!

[@chrisleech1565]

Most refreshing thing so far this weeknd. Thanks @Bitluni. Such brilliant library and coding. I have not done Micro Python but have begun Lua in Mach4

[@SimonRumble]

In case anyone's trying to print the undimensioned STL files, I set the height of the entire print labelled to 42mm and printed and it fits perfectly. This is for the "30mm" (distance from LED to diffuser) file.

[@electronics.unmessed]

Nice idea! And a lot of substance in your video! 👍👍👍

[@Clark-Mills]

With the black 3D printed baffle you could dip the assembly in silver (or white) paint to improve brightness. Spraying or brushing would be too hard given the shape. Draining after dipping should work well. Nice project, thanks!

[@Ziraya0]

Techmoan recently took apart a really bad ikea sound visualizer thing, it used a microphone to "detect" the "beat" and step through a low res gif. More interestingly it used an LED grid like this and a frosted translucent plastic panel of lenses to create large circular "pixels" from each LED. With a clear-ish filament you could probably 3D print a similar pixelizer panel to produce a look like this, but with much less depth, I expect less filament, and you could potentially put a gap between the pixelizer and the LED panel, which would , if vented top and bottom, create a natural convention of air across the LEDs to help keep them cool

[@LunesPeltier]

I am very interested in a C/C++ version.

[@Patrick_Black]

[@bitluni]

🤐

[@linuxgeex]

@bitluni you should spray silver spraypaint on the inside of the cover to avoid cross-channel leak and material absorption of the light which just wastes power.

[@PuchMaxi]

@0:25 Hey Bitluni, what happened to the Pi Pico with Ethernet and PoE design? Do you sell it, or can we buy it somewhere? 🙂

[@0sliter0]

UDP stream is the most efficient way to send pixels to the RGB strip. Also using C++ would allow you to do it in 60 FPS. I did similar project with esp8266 and 288 led strip. And also, you can go to your router settings and assign static IP to the rpi so you don't need to update it everytime...

[@LunesPeltier]

Hello, I have a similar project that I am working on. Could we exchange on the C/C++ solutions you found?

[@0sliter0]

@@LunesPeltier yeah, but I'm still experiencing some troubles reconnecting to the server (from esp). If you can improve on that it would be great. I'll ping you in Discord

[@mousefad3673]

Nice to see 'Bob' making an appearance.

[@drksbr]

You can use udp socket to send data.

[@everydaytinkerer]

This is totally awesome, I will need to look into this myself. I guess you could modify the case to have sections to daisy chain them together as well.

[@OMGWTFBBQSHEEP]

Supercool end result! Do you think it's possible to connect it directly to a computer in order to get a higher fps?

[@bitluni]

I tested CDC with esp32 S2 before tt's certainly fast

[@OMGWTFBBQSHEEP]

Thats promising, would've been a cool moody light to have on my desk:D maybe i should build one!

[@raspberrypi]

Ah, this is brilliant!!

[@usefulelectronics]

Wow this is awesome!! Is it possible to use LVGL library with such RGB LED matrix? :D

[@chain3519]

I don't know of a ready made solution, but if you make an LED driver function compatible with their format, it would definitely work. LVGL just passes data to the driver

[@Pixelcrafter_exe]

if you wire the neopixels directly to the pico, you might get problems in noisy environments, since the rp2040 runs on 3V3 and the ws2812b expects a 5v signal voltage

[@Scootercorn]

I was looking for something like this as I have those panels laying around but I don’t know how to send matrix image data to them. Thank you!!

[@LevisTovi]

Hi, great work. Can you please share the link to the livestream you’ve showed at 3:30? Thanks

[@teslastellar]

Putting a dark plexiglass sheet in front of the panel will diffuse the light and make it look much better.

[@leadscollector]

I have a Pico W. I have tried this even on a basic setup and only ever see 3-5 lights come on seemingly at random... Any ideas what I might be doing wrong. It just wont work

[@ShahZahid]

i made a similar thing about a year ago based on the esp8266, it has clock, weather, patterns, drawing, games, animations and streaming via jinx! capabilities, i think you need better diffusion tho i used 2mm thick frosted acrylic and a sheet of tracing paper (or wax paper) behind it, and the leds were completely diffused

[@Yhetti]

What happened to the RPOE? I've been waiting to place an order for 10 of them for two years

[@pfriedel]

I ended up having to put ears on the corners to keep them from lifting. The rest of it printed up beautifully, and then I tried tearing off the ear like I usually do, forgetting that the bottom layer is no stronger than the ear. Oops! It looks nice with faux marble filament anyway and I'll take a second swing at printing it later on.

[@owenhill22]

Awesome! Thank you for this tutorial. I printed a single initial layer of black PLA at 0.28mm but the light can't pass through. Is there a way to increase the brightness of the LEDs?

[@algeroth]

Another question set :), you can connect to any gpio (GP) pin right? And what if you wanna join a couple of this matrices? Just connection output to input and one data gpio will do? Finally how should both be powered?

[@LooLL321]

ssid = 'lab' password = 'booobies' nice one! :D

[@Keeping_IT_Simple]

Looks like I finally might have found a reason to dig out my long disused 3d printer - I hope it still works . Apart from the rp2040w I have the rest of the components... Thanks for sharing this , a great project ! If you don't mind me asking how do you get such great video of the led panels in operation? I have just started making video & I struggle loads with this so any hints would be appreciated!

[@bitluni]

ESPs should work fine

[@valmikibiswas9337]

Hi thanks for this tutorial. I'm trying to run a screen share using: 1. RGB LED matrix - 64x32-pixels 2. i75 with Pi Pico W onboard matrix driver Am getting no errors, but nothing is showing up on the matrix. I have altered the xRes and yRes but no success. Is there something to do with the pin or anything else? Any guidance would be helpful. Thanks.

[@vasiliyivanishvili9025]

Cool project! May you check this panel brightness? Without diffuser of course.

[@MrHuntPowa]

Have you tried to use the second core of the pico to improve the framerate?

[@clockworkspiral]

Ah, eternal love-hate relationship with the WS2812-type LEDs, worked in enough things that have zero redundancy on the serial line, meaning the moment an LED went out it would take out everything after it in the chain too. Makes the newer WS2813-type ones with their redundancy pin seem really appealing after that .-.

[@thetheoryguy5544]

Would a Pi Zero W be even better? I want to start a project using 4 64x64 matrixes to make a mini LED board for my DJ set. I want to be able to sync the visual effects from virtual DJ's video mixer to one of these over WIFI. I'm new to this but want to learn basic coding and scripting.

[@jjackFrenchi35]

hi, is it possible to do the same project on a raspberry pi 4 with 4 P5 led matrix panels? 🤔😀

[@bennguyen1313]

There's a 5x5 ESP32-based RGB board I saw on "Bringing the bling with MicroPython".. do you think one could modify the code to transmit the Windows' Start logo to that tiny matrix?

[@sagarmakhija1994]

Really nice work, Can we connect 10 Matrix to improve the image quality? Does pico w capable of it?

[@conorstewart2214]

In the pico C sdk there is a socket library now, based on lwip, I think very similar to how it’s done on the esp32 so it may be worth trying out.

[@SidneyCritic]

I wonder if you can put a lens on each cube and project it - lol -.

[@algeroth]

Can you wire/connect power and gnd directly to 5v and gnd pi pins?

[@Maxjoker98]

I think even if you daisy-chain them, you'll always have an "open end", and thus "spare wires". You should probably not create any loops.

[@NilsRohwer]

This is really fantastic, could you do something similar with an esp32 or doesn't it have enough punch?

[@vault-techec7257]

Raspberry Pi Pico VGA or HDMI?

[@bitluni]

why not

[@liongames13231]

What if you only update the pixels that have changed to reduce the data being sent?

[@hippopotamus86]

I doubt that is the issue, the data is minimal compared to everything else it has to do.

[@ThanassisTsiodras]

It's been one and a half decade since then... but I am pretty sure you are playing on your screen Farbrausch's Masagin from Nvision 2008.

Nice and inspiring video! I really want to build some kind of led screen with e.g. a clock for running events and similar, that can be set and controlled remotely, but then these led matrices are too small. You showed that it's possible to chain them though, but could you make a video on that topic to easily extend the size a bit?, but without making it a ping-pong wall :)
