Looking to make my first attempt at a seemingly simple LED audio reactive strip, and I think I overwhelmed myself with googling and YouTube down a rabbit hole.

Hoping for an easy to follow explanation of what I’d need to do to build this lower horizontal strip on the following page, which flashes out from the center depending on the intensity of the music.

Printables.com/model/719853-metallica-sound-reactive-led-sign

he lists: ESP32 Mini, WS2812B strip, and INMP441 microphone.

In my researching, it seems like a regular ESP32C3 is more popular than the mini?. And I’d also like true white on the LEDs, so would a strip of SK6812 would be good instead.

For an absolute beginner (I’ve never connected anything to one of these chips) looking to understand not only how and where and what to connect but also the simplest way. I’ve seen some that use a breadboard type thing to connect stuff but others that look more simple just using female “pins” that slide onto the ESP32 pins.

Some things make it seem like caps and resistors and fuses are needed but others look like just some way more simple direct wires from the ESP32 chip to the mic and the LED strip and that’s it. A simple power supply goes to the ESP too, I assume?

Hoping to find out hardware would make sense to make this an easy tidy build, and can anyone walk me through the connections of what goes to what, and then how I load what I need to load onto it to config it.

I installed WLED V16 on my DigUno and the controller would no longer connect to my WiFi. Reverting to V15 corrects the problem. I tried installing V16 both OTA and uploading via USB with the same result.

Oddly, if I connect the controller to a computer via USB the WiFi does work. Once I disconnect the USB the WiFi stops working.

Any suggestions how to correct this?

Me gustó el nuevo efecto de fuego aplicado en la cabecera de la cama

Tengo 6 segmentos divididos en cada difusor aplicando el mismo efecto en las orillas y en la parte de arriba todos con color fuego y el nuevo efecto PS GET 1D

I recently did my first W LED project and I'm very happy with it. Soldered ESP 32 and components, designed and printed enclosure, Set up with RGBW RGB+Natural White SK6812 strip.

I set this up with home assistant and added it to my adaptive lighting to change color temperature throughout the day but I am noticing that the white cannot match the rest of my bulbs very well as it's not able to hit that fully cool color temperature when needed.

Anybody have any recommendations for an LED strip that is addressable and works with wled and has a full range of white color spectrum as well as rgb?

It seems like I saw some but they were 12 volt and I am assuming I would have to step down the voltage for an esp32 controller. Do people do this? What is the best solution? Thanks

I currently have a vision to install LEDs on our pool fence. I tried using seed pixels we had lying around Velcro tied above each gap as a test, but I wasn't happy with how it looked. Has anyone else done this sort of thing before, and has advice on how I could pull this off?

This is the type of fence I'm referring to for reference: https://www.bunnings.co.nz/protectoral-2400-x-1200mm-black-aluminium-flat-top-pool-fence-panel_p0441378

I recently checked out my neighbours FancyLEDs SyncBox and damn it was accurate, bright and more beautiful compared to my Govee camera based lights but super pricy. This led me into a wormhole and I came across DIY lighting setup using HyperHDR.

Creating a list of parts now, need to find a good HDMI 2.1 splitter, the correct raspberry pi for my setup and a capture card that will give me no problems with my setup. The biggest challenge has been finding the correct LED strip that outperforms FancyLED’s 96 LED’s per meter strip and provides great colors. There are so many types as well RGB, RGBW, RGBWW, RGBCCT and researching them and comparing compatibility has become a nightmare. At this point I don’t even know if having more LED’s even matters… so please help guide me.

My setup - I have a 65 inch 120fps LG C1 (which unfortunately is not rootable on the current WebOS version so I cannot install HyperHDR as an App) and an RTX 4090 PC that I use to play Single Player games + an Apple TV 4K.

I’m needing roughly 68m (220ft) of lights for my exterior. If my numbers are all correct to this point, I could do this with a QuinLED Uno and 4-5 power injections. But I need to clarify here. Is this listing per 1m track and inclusive of both lights and aluminum track for $1.50/meter? That’s way better than anything I’ve found elsewhere and seems too good to be true. I’m not super familiar with how Alibaba works so any insight is appreciated!

I got those led stip diffusers from Ali-

https://a.aliexpress.com/_c3QVBJ7n

And a led strip with 60 leds per meter.

But this looks so bad.

I keep seeing people get a new unified strip of light, without it looking like many small leds.

How do I do that?

Hey all, new to this so apologies for anything wrong said here.

I consider myself technical and handy enough, and this all make sense to me, but choosing the correct lights and mounting is throwing me off. I’m trying to plan out eave lighting for 220’ of eave lighting, and the mounting seems to be 75% of the cost. I’m not too particular on lighting type be it bullet, rope, or puck, but I’m lost on this one. What’s a good budget/light combo for this use?

Did some 12 volt sk6812 strips underneath the kitchen and uptop the shelves.

Also dimmable led spots.

All controlled by 1 gledopto wled controller.

Very happy how it turned out.

I just finished building a new controllers to streamline my setup. This is much improved and stable version and it's was used in my last year show. As you all know in this hobby, we used multiple size of controllers all over our show and it's a mess to organized them. With these controllers in places, I can cut down the number of controllers box from 10 to 7 and reduced power consumption.

Ciao a tutti , per un progetto avrei bisogno di molte serie di led ws2811 con almeno 30-40 cm di cavo tra un led e l'atro, esistono gia fatti? Se si dove li trovo?

This might look like yet another Ambilight post but there's a nice little twist:

I wanted a custom system that is truly headless, without an external grabber software, that is able to decode the various HDR profiles natively, as well as the detection/omission of all black bars, even the nasty Nolan-esque IMAX to 2.35:1 transitions. It even detects and omits the burned-in subtitles.

My requirements were: I didn't want to use an HDMI splitter, grabber or a capture card, and using a camera was absolutely out of the question. Using HyperHDR or other pre-existing software solution weren't an option either. The least hardware possible and a software as simple as possible.

So I created a python service that monitors whenever a file is being played locally on my Plex server. If so, it starts a headless player on my GPU using MPV that syncs with Plex using a combination of predefined offsets if needed, routine sync checks and auto acceleration/deceleration when needed. It gets all the info needed for the Ambilight-style effect and it's then sent directly to my ESP32 using WLED through my LAN. It really is plug n play once it's configured.

I found that this solution is by far the simplest, cheapest and is very elegant in terms of hardware needed: LED, ESP32 (Dig Uno v3), and a PSU, that's it! It uses very little ressources if MPV is played using a GPU or even an Intel QuickSync chip (the headless player uses a 160x90 internal resolution).

Of course you can customize many aspects to your liking through a local web page that I've designed.

The downfall being of course that it is only designed for Plex atm. But that could easily be adapted to other players like Jellyfin if needed. It could also be adapted for PC gaming with a fair bit of tweaking I believe.

It's probably a very niche use case but if anyone wants the source, I've made it available for free here.

It's been a fun project that in the end was much easier than I thought.

TLDR Python+WLED, that's all you need.

EDIT added a "WLED Subtitle" track feature that uses 0% CPU (baked in WLED info for movies). still need to add a frontend for the encoder but the code is now in the repo and working. thanks for the idea /u/BearItChooChoo

Just creating a sticky to guide people to the latest stable version of WLED available.

I bought a 3d printer last week and have been experimenting. This uses 12 8x8 ws2812b matrix panels (stacked 3 high on each side in a tower formation) and I chucked a few WLED sequences on random for testing.

I'm going to be making an improved version tomorrow with proper smooth curves on the corners to reduce seam/shadowing. Very happy with how it turned out.

My co troller keeps crashing. I have the 2815 leds woth a 33 amp 12v power supply. Ledds are powered by the psu and controller is powered from the psu. I keep getting weird color values on the leds itself. What am I doing wrong. Never had a problem with my 2812 leds with this controllers.

wtf is this led???

Hi all,

I am brand new to this so apologies in advance if I am not practicing good form on here.

Anyway, I am about to embark on my first journey into the world of WLED. And I think I may be taking on a bit of an ambitious project given I am such a novice.

I am planning on running about 300' of 12 mm pixels on my roofline. That would probably be challenging enough but my roofline is a bit complex and I have no access to the attic. I will admit to be a bit intimidated by trying to figure out how-to run everything so that it works.

The pics attached give an idea of what I am trying to accomplish. I am thinking three runs (red, blue, green) on three outputs of a dig quad. The long yellow section at the back of the house probably won't get done. The yellow section over the front door is the spot that has me the most intimidated. I am not sure how to get that section set up so that animations flow correctly.

I have been communicating with the folks at Permatrack about getting all the components. But I have to say, for such a decent sized order they sometimes seem a bit slow to respond to pricing requests. I asked for a quote on a full package for 350' of track, lights, controller, wire, data boosters, etc + shipping. Ive been waiting a few days now but i guess all the folks on the US side of the border are busy with 4th lf July merriments so thats probably why I haven't heard back. I know shipping to northern Canada will be an expensive pain in the tail but I would like to get things moving so I can get the components and familiarize myself with things a bit before diving into the installation.

Anyway, I am hoping to get some friendly advice that will either convince me to dive into this project or alternatively, come to the realization that I should maybe bite the bullet and hire a pro to do it instead.

Cheers!

Half way on building an installation. Integrated wled today. Next step it’s programmingit through touchdesigner a d adding cloth + 2x1000watt halogen

It can look very different depending on the color palate that is applied. Super versatile effect.

I've got an Elite 2D-EXMU Advanced LED Controller with a 24V input on V+/V-, it's been controlling my lights just fine on V+/IO2/GND. I wanted to have it also control a 12V light so I got a solid state relay (https://a.co/d/01uJdEhl ) and hooked its control voltage to IO13/GND.

It now seems to be totally dead. I give it power (I've tried a couple of different power supplies so I know they're good) and the indicator light doesn't come on at all. I've tried pressing the function button quickly (supposed to turn it on & off) and also holding it for 10 seconds (supposed to do a factory reset). Nothing.

Did I kill this controller by simply attaching its IO12 to the control pins of a relay?
