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.

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.

It should be able to carry enough info considering the wall's resolution is pretty low, and it would solve your cable problem.

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.

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).

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 Жыл бұрын

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 Жыл бұрын

@@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 Жыл бұрын

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...

Pretty cool. Of course, you can now find a TV almost as large for less than double that, which would make for a much nicer display...

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.

I built this and the software side was a bit of a mess. It worked enough to make me happy, but it wasn't good enough to use easily. Recently I realized that I could flash WLED to the ESP8266 which made it immensely easier to use.

@TheTechRandom 5 ай бұрын

I’ll have to try the WLED matrix effects. Does your setup use a single panel or multiple?

@zeekjones1 Жыл бұрын

Would the software be able to handle 24 segments instead of 4, as long as I had a stronger server? I'm looking at making a much more dense one of these. _(looking at those tighter 144 pixel addressable strips, and stacking them 6 pixels tall for trim pieces.)_ _I have an extra dedicated router, that I can force channels(limiting WiFi traffic), and a handful of mini PCs that any one would have plenty of compute for a dedicated server._

@TheTechRandom Жыл бұрын

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.

Dumb question for you.. Did you affix all 4 panels together in a solid fashion? It looks like you put the diffuser over the whole, 4 panel assembly. I’m debating between that for a seamless looking, solid unit finish. But I’m planning on using it as a backdrop and I think being able to stand the 4 up vertically, with some space in between could also look sick. Something like this- __ __ / \ 🤓 lol, if that makes sense

@@TheTechRandom fantastic! Thank you. That’s the route I’m thinking. Cause like you said, adding color and movement as a backdrop.. and it would be even sick to set the 4 panels around your table at like a convention type event. Super eye catching and a lot of perceived value. Thanks again for taking the time to share and make the tutorials

@ZOIMIBiIE 10 ай бұрын

Sorry to keep bugging you. I’m about half done with printing and chomping at the bit to get assembling Like I’d mentioned, I’m considering using this at say a convention type event at my table/booth. It occurred to me though. I’ve been thinking to make one video, but have the source video divided into 4 frames to correspond with each independent panel. So you’d run one video as the source, but each panel would appear to play or display something independent. If it turns out alright, I could send you the grid overlay to use as template to add to the GitHub or instructable. At this event I’m aiming to bring it to in September, counting myself it’s a group of 3. So I was thinking about displaying something to represent each one of us on our own panel, and then have our socials listed out on the fourth.. or something to that effect Also on the P1P I’ve managed to cut each pixel panel down to just shy of 2 hours. At the .12 factory settings it’s over 3. But I increased the layer height a bit and on sport mode comes down to 2. I’ve found that if I flip it to ludicrous mode after the first few layers are done, it makes it much much quicker.

This is a great video. I do have 1 question. The esp32 is a 3.3v device. The LEDs are 5 volt devices. Why isn't there a logic level shifter? While I'm asking, why not use 12v LEDs for better power distribution?

@TheTechRandom 5 ай бұрын

Great suggestions. These LEDs are 3.3v tolerant so no need for a level shifter

@JamesFraley 5 ай бұрын

@@TheTechRandom thank you for the answer. It really is a cool wall and great video. I was reading the WS2812B datasheet. It says the input voltage is -0.5～VDD+0.5. Do I understand correctly that means the input voltage is 4.5 to 5.5 volts? And, you're saying that the LED are capable of working at 3.3v. Although I'm sure the manufacture would say don't do that. Thanks again.

Is the 3D Printer also in the calculation? Or do you need the printer and then have costs of under 500$? All in all very cool project. At first i thought, i wont build something like this. but know im not sure anymore.

@TheTechRandom 4 ай бұрын

It was included when I did the calculation. Each of the 4 panels is about $100 and the printer is $120. Things are a bit more expensive than they were a year ago so I’d recommend going through the full list of supplies you’ll need and getting a better idea of the current cost before you start buying things

@mbennett2663 Жыл бұрын

This looks awesome and I've been thinking about creating one . This is the first time I've seen it done w LEDs strips though. Usually I see it done smaller w led matices. Is there a reason behind u choosing strips? Cheaper? Easier to program? I have someone that wants this done and I'm bouncing back and forth trying to find the best way to do it.

@TheTechRandom Жыл бұрын

The LED strips are cheaper and require much less power than the matrices since the pixel density is lower. If you want to cover a large area, then this is the best solution. If you want a high resolution, it might be better to use the matrices.

Hi there, amazing project!!! You inspired me and I'm building my LED wall, I just assembled the 1st panel. You also inspired me to buy a 3D printer which is printing the grid right now. I went with my own design, a grid with curve cubes printed with white filament (I didn't like the Diffusing Cloth). What I don't know is how you managed all those cables and power supplies… I've been thinking maybe it is possible to use one power supply for 2 panels if you lower the maximum brightness of the LEDs, so would be 2 power supplies for all 4 panels. Or maybe a better power supply for all 4 panels? What do you think about it? Or what pro tip can you give me to have an easier time managing all those cables? Thanks!!!

@TheTechRandom Жыл бұрын

You can definitely only use two power supplies if you set the brightness low in the code. If you want to cut down the number of wires make sure you use a thicker gauge and connect it to multiple points on the panel so you get enough power to all pixels.

I clicked the link and say the 300 light option in the same length, Hence doubling the resolution, Is this in fact that simple, I know the 3d print would also need adjusted but is it as simple as purchasing the 300 instead of the 150 ?

@TheTechRandom 7 ай бұрын

You’d also need to by twice as many strips to cover the same area since you’ll need to put them closer together. If you edit the code and reduce the max brightness to 25% then you should still be able to power everything with 4 supplies. Keep in mind that the max brightness test and single matrix test don’t have an easy way to set a low brightness. You’ll most likely need to run everything in a wired configuration some the wireless signal already lags a bit this lower resolution
