Screen share ANYTHING to this matrix! (Pi Pico)
HTML-код
- Опубликовано: 25 июн 2024
- My first take on MicroPython and the new Raspberry Pi Pico W. Had some struggle wit the lacking ram but at the end a simple screen share worked which allows you to project anything shown on your PC screen to a nice LED Matrix display wirelessly. The case with back projection screen is printed in one Piece. It's a super simple project to make on a weekend. I have better Websocket versions coming so subscribe to not miss that.

Could you 3D print direct on to a diffusion firm, and just skip the first layer.
this is genius! will try and upload result
Or maybe switch filaments between first and second layer. Transparent or grey for the first layer, and Black for the walls.
@@bitluni maybe get in touch with Thomas Sanladerer
I feel like this should run "the game of life" code, auto resetting on some basic conditions. Super cool board
Even langrangs ant simulation
The WLED firmware for ESP(8266|32) has a Game Of Life prebuilt effect.
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
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!
Pretty sure we got Rick Rolled in low res. :). Really cool expandable project!!!
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!
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 !!!!!
It's funny that when I see the thumbnail on my feed I know it's one of your videos. Thanks super useful!
Nice idea! And a lot of substance in your video! 👍👍👍
Ah, this is brilliant!!
Very cool project!!
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.
Cool project!
Love it!
The new thumbnail looks good!
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++
Hello, I have a similar project that I am working on. Could we exchange on the C/C++ solutions you found?
I would like to understand what you have done also!
I build this with wled and send a json to update.
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.
Sounds nice, shouldve put up a video of it!
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!
Thank you so much! It work!
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.
Nice to see 'Bob' making an appearance.
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.
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
Cool Masagin on LEDs 😁
great and quite short one !
That’s nice 😍
Right here with ya, bro
cool Project
Nice work and bring new ideas. Super Typ :-)
Great video
OMG, I fell like I've been rickrolled 😱
Great job 👍
impressive video
ssid = 'lab'
password = 'booobies'
nice one! :D
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
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!!
@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.
This is really fantastic, could you do something similar with an esp32 or doesn't it have enough punch?
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 :)
You can use udp socket to send data.
Cool project! May you check this panel brightness? Without diffuser of course.
I didn't expect to get Rick Rolled by Bitluni at the end!
Not just the end
4:38 bo0obies the blur only works if you don't miss a frame!
🤐
Whoa cool
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. Very cool :-) As a demoscene fan, surely you realise we expect a futute video with an assembly implementation of the livestream engine - none of this slow interpreter stuff! 😀
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?
Really nice work,
Can we connect 10 Matrix to improve the image quality? Does pico w capable of it?
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
Nice !
Have you tried to use the second core of the pico to improve the framerate?
Great Job! I hope your additional implementing on ESP32 and Arduino IDE.
Thank you for making a video explaining all the essentials of tNice tutorials software. You really helped understand the software more, thank you
I am very interested in a C/C++ version.
Putting a dark plexiglass sheet in front of the panel will diffuse the light and make it look much better.
Wow this is awesome!!
Is it possible to use LVGL library with such RGB LED matrix? :D
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
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 .-.
Subgenius!
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!
ESPs should work fine
Hi, great work.
Can you please share the link to the livestream you’ve showed at 3:30?
Thanks
A Websocket stream might be sufficient to send the data :))
When did you guys watch Masagin? That demo is awesome :D
Supercool end result! Do you think it's possible to connect it directly to a computer in order to get a higher fps?
I tested CDC with esp32 S2 before tt's certainly fast
Thats promising, would've been a cool moody light to have on my desk:D maybe i should build one!
5:06 subtle.
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?
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?
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...
Hello, I have a similar project that I am working on. Could we exchange on the C/C++ solutions you found?
@@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
Can you wire/connect power and gnd directly to 5v and gnd pi pins?
Do more stuff using pico w
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.
RR'd twice in one video, NICE.
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.
Fps can improve also with smaller led try it 😉
Must be nice to have a pico w
I've ported to ESP32, is exactly the same code, but I've changed the connection status from != 3 to != 1010 and run as expected :D
I wonder if you can put a lens on each cube and project it - lol -.
everytime I try this I become this error code
" Traceback (most recent call last): File "", line 82IndentationError: unexpected indent "
can u explain what this mean?
Just move the line back and forth using tab space and try again
can hub75 boards be used with wled?
hi, is it possible to do the same project on a raspberry pi 4 with 4 P5 led matrix panels? 🤔😀
What happened to the RPOE? I've been waiting to place an order for 10 of them for two years
I don’t suggest wifi share use vga or even hdmi also try with smaller led and it will be perfect
could you do screen share with an esp32?
@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? 🙂
Has somebody implemented this but with a different display e.g. 64x32 rgb led matrix. I'am not finding a good and easy to use micropython library for such a display.
I think the Pi Pico W is the most fun and cheap way to learn all kinds of programming disciplines: IO, memory, APIs, logic…
@@wesleyswafford2462 esp8266 we're single core, but the newer esp32 are dual core. Haven't tried the pi pico w since when I bought stuff for my wireless led matrix project the esp was cheaper but it also is a golden hammer.
Can you please add a command to clean display in your esp32 VGA out library. As it will be very useful for displaying moving data on screen.
How fast refresh rate can be?
What if you only update the pixels that have changed to reduce the data being sent?
I doubt that is the issue, the data is minimal compared to everything else it has to do.
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.
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
Hi.
Can this be ported to a esp32?
why not try a spi tft like a micro display next?
Danke!
Thanks! ☺
Thats the thing. you feel like the display needs to be bigger.
Ambilight ?
Your wifi password is the same as mine :-D :-D
i wood like to make some thing like this butt offline without wifi as i only have the peco i only plan to have one gif of some eyes blinking evey 5 or so sces
Raspberry Pi Pico VGA or HDMI?
why not
I REALLY like your wifi password
4:38
ssid = "lab"
password = "booobies"
nice
Immediately I'm thinking, "What about 4 panels next to each other?"
Or... 9 ?
yes
@@bitluni I tried 4 panels -- all 4 light up, but the image is jumbled. For example, I made a 2x2 grid test image with a Red square, a Blue square, a Green one and a White one. When the image is shared to the Pico, LED panels 1 & 2 have red and blue lines intermixed, and panels 3 & 4 have green and white lines intermixed. I can't figure out what to tweak in the code to fix this -- any suggestions?
Is that Rick Astley at 5:08?
😬
