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.

@bitluni Год назад

this is genius! will try and upload result

@lostname1781 Год назад

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

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

@arxaaron Год назад

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!!!

@Stabby666 Год назад

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++

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 !!!!!

@raspberrypi Год назад

@multiplysixbynine Год назад

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 Год назад

Sounds nice, shouldve put up a video of it!

@SimonRumble Год назад

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.

@Clark-Mills Год назад

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!

@StormBurnX Год назад

The new thumbnail looks good!

@conorstewart2214 Год назад

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.

@Ralfonso_Di_Rosetto Год назад

cool Project

@inlywang8157 Год назад

impressive video

@ShahZahid Год назад

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

@Scootercorn Месяц назад

@Ziraya0 Год назад

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

@Pixelcrafter_exe Год назад

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

@drksbr Год назад

You can use udp socket to send data.

@dormitor187 Год назад

Nice work and bring new ideas. Super Typ :-)

@linuxgeex Год назад

@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.

@HugRunner Год назад

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 :)

@abdulr5320 Год назад

Nice !

@vasiliyivanishvili9025 Год назад

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

@Robin_Nixon Год назад

I didn't expect to get Rick Rolled by Bitluni at the end!

@ytdlgandalf Год назад

Not just the end

@NilsRohwer Год назад

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

@teslastellar Год назад

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

@ThanassisTsiodras Год назад

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! 😀

@owenhill22 Год назад

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?

@clockworkspiral Год назад

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 .-.

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 Год назад

ESPs should work fine

@TecSanento Год назад

A Websocket stream might be sufficient to send the data :))

@0sliter0 Год назад

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 Год назад

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

@pfriedel Год назад

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.

@algeroth Год назад

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?

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

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.

@@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.
