Hey man! Just stumbled upon your channel as I was researching LED Walls because it's a project I've dreamed of doing one day, your version is definitely the most accessible, budget friendly and clever i've seen so far :) Thanks so much, I miss the days when I was just a freshman i college and would go to maker fairs and hackerspaces, now that I am older and have been working full time for a while i had almost forgotten how much fun combining engineering and creativity for cool projects such as this can be. I'm super motivated to start making stuff again, huge respect for not only being able to do it but also recording the process and uploading it to UKposts. Keep it up!

Very cool project, As an open source software contributor it pained me to hear that you forked a project, fixed something that wasn't working, and didn't raise a Pull Request. That way, as long as the original maintainer is still around, we can have one working piece of software instead of a bunch of forks. It might also be cool to make a version of the app which supports "profiles" so you can load all those settings or set them as a default from a config instead of setting the baud rate etc. every time you use it.

@flatfingertuning727 Рік тому
I designed and had built a signboard for a rock band with 2500 LEDS wired as ten strings of of five connectorized strings of discrete "bulbs". The ten strings were driven using an AT750 CPLD to demultiplex the SPI bus from a Raspberry Pi. Every pair of bytes from the Pi sent one bit out each of the ten strings of LEDs. Doing things this way allowed a much higher total data rate than if all LEDs were in one string. The one problem with the sign is that many of the blue and green LEDs within the bulbs are failing. even though I've only been driving them at half brightness outside of a few flashing effects. I hope you have better luck with long-term longevity than I have.

I wonder if foaming Lightweight PLA would be a better option for its low weight and high volume. From what I understand, you could cut the total plastic 40% by weight while still having the same final build volume. Not sure if that is any more or less cost effective than some cheap spools of PLA though, I initially thought about this as a way to reduce the amount of filament needed.

You went big. Recommendations for safety and functionality upgrades: 1. Add inline automotive fuses on the DC outputs of the power supply in event of an electrical short, the fuse will trip and prevent the PSU burning your house down. 2. Improve FPS and prevent throttling your home network going all wired with a Teensy and Octoboard. Just one Ethernet cable can carry all that data to the display. 3. Alternative wireless options include PixelBlaze or WLED running on ESP32 with an output expander. 4. Consider using RGBW strips which will give better colors and reduce power draw for white or pastel colors.

Plus it could be cool if you use multicast/snapcast (I think is the name) to be able to like multiple raspberry pi's to play the song in different rooms with the music synced and maybe a panel in each room set to the audio visualizer.

You should use sk6812 rgbw for that extra white pixel or ws2812b, both in matrix variants 8x32cm. The pixel density is like 144 leds per meter and it gives you much higher resolution and they are fkexible with 3m sticky side at back. For the controller go with esp32, inatall wled and then use it only as art-net reciever. Btw with one esp32 i was able to send data to more than 6k ws2812b leds on 30fps. I'm using resolume arena to send video feed to the esp32. If i want to screen capture i'm using NDI inside resolume and it works without any problems.
@TheTechRandom Рік тому
Why would I need an extra white pixel for a video wall? 144 leds per meter would give a better resolution but it would also put the cost of this project through the roof. The goal of this project was to cover as much area as possible for a low cost so your suggestions are valid but they don't apply to this project specifically.
@Myrinero Рік тому
@@TheTechRandom @Tech Random the price is almost the same, so why not? :) Price of one 8x32cm is around 10-15$ depending on brand for ws2812b. For a screen 2x1 meeters it's goins to cost around 250-300$ for the leds. With the matrix style leds you wont need any 3d printing also, just slap those leds on something and because of the density you wont need any diffuser, or if you want you can add PMMA opal layer for example on top.
@TheTechRandom Рік тому
For a 2x1 meter array I would need 13 x 7 of these tiles. The best price I can find on Ali express is $13 each bringing the total cost to $1,183. I'm not sure how you got $300 based on the numbers you gave...
@JasperJanssen Рік тому
@@TheTechRandom 12x6 for 96x192cm presumably, but 72 modules is still 720 bucks even if you are able to find them for 10 bucks each. And you definitely still need both diffusers and a printed mesh to get a good result. But you would get a much higher density, so there’s that.

@tz496 7 місяців тому
there's 144 pixel/m ws2812b strips, for example. if you mount those very close to each other there's barely any space between each LED. just will have to be mindful of increased power consumption and how quickly your amount of pixels increases (making them harder to drive at higher framerates).

@tpaairman 4 місяці тому
Just some notes on the connections. First, when soldering the wires to the 8266 board, the wires should have gone through the board, not surface mount soldered. Going through the board will give a stronger connection. Second, when connecting the line cord to the power supply, you have black and white reversed. Technically since it's AC, it will still work, but also, you referred to the white as live. It's not live, it's line. You also have your line cord wires fed the wrong way. When you bend them, they should have been fed from the left side of the screw, not the right, since the screw will push the wire from left to right (at the top) which will help pull the wires under the screw better. Having it looped right to left can cause the wire to slide out of the screw as it is tightened.

@kataseiko 3 місяці тому
A little tip from an electrician: Never just put a stranded wire into one of those connections without a ferrule. You can get a thousand of them for maybe 5 bucks and you'll avoid a fire in your living room. If one of those strands happens to cross the terminals, you'll be lucky if the RCD ("residual current device", sometimes "RCCB", "residual current circuit breaker") catches it. If you're in the US, you probably live without an RCD (your electric grid and laws for electric installations are garbage) and your strand will quickly reach 1100 °C (2000 °F), likely causing a small fire before the stand can melt.

@TheTechRandom 11 місяців тому
I think you would need to go with a wired connection to get a decent refresh rate with that many pixels. My four panel setup maxes out at around 18 frames per second so 24 panels may only be able to get 3 fps. Also keep in mind the power draw and brightness of this type of display. Even at a low brightness you’ll want a strong diffuser so you don’t need sunglasses to see the image.

Adding DMX support would require additional hardware and the firmware on each ESP 8266 would have to translate that data into something the LEDs can read.

Really cool project. How different it would be if you want to use a webcam ? I'm trying to find how to do something like that.

If you skip to the end of the video I demonstrate using my computers webcam as the video feed. Since it mirrors my screen I can just use the camera app that comes with the PC.

i would really like to see this done with the higher density 60 LED/meter (300 pixel) strips for a more detailed image.

The hardware and typical home wireless network can’t handle it. Would need to upgrade the design and cost will go up.

Amazing work! Any ideas for an outdoor/weather proof housing?
@TheTechRandom Рік тому
Plywood, acrylic, and caulking might work

@@TheTechRandom didn’t think of acrylic at the time... hmmm I got the brain going now haha Appreciate it!

A few things to try first: flash the FastLED test to your panel to make sure the leds are set up correctly. You’ll also want to try the LMCSHD test with the panel plugged directly into your computer. Once both of those tests are working, then you can move onto the wireless code. Each level will likely require some debugging, which is an important skill for embedded development projects like this, so it’s good to start small and work towards the final version. With LMCSHD I’ve noticed a lot of issues with the Serial->Connect button not actually connecting to the board. If it connects properly, the size will be set automatically. Otherwise you will need to connect again until the size gets set. Make sure you’re using the correct bitrate (bpp) and baud rate for each mode. For the LMCSHD test I think it’s a 24bpp bitrate but for the wireless version it’s only 16 bpp. Good luck!
