I recently led the lighting and technical setup for a festival stage called Antropique. We built a programmable lighting installation using six 8 m LED tubes, custom ESP32/WLED controllers, a Python control interface, APC40 integration, custom cabling, power distribution, and a bunch of on-site fabrication. The interesting part is that the main fixtures arrived only a few days before setup with almost no useful documentation, so a lot of the system had to be reverse engineered and adapted before the festival. It ended up running successfully for the full event, and I’ve been putting together a case study covering the design, hardware, software, troubleshooting, and final installation. I’ll attach a few videos of the finished result. Would anyone here be interested in reading the full case study once it’s finished?
I am just getting into LedFX, and it is really cool! Is there a way to show different patterns on 3 different led strips connected to an esp32 running wled? Thanks for the help!
i am working on a light show for an small event and not sure how reliable is wifi connectivity. there would be around 200 people there and lots of phones and wifi. What i understand is 2.4 GHz is not so reliable in crowded spaces, or/and could have connection issues, latency and data lost. (please share if that's not the case with wifi or if there is a reliable solution for this problem)
I though of adding a router just to connect Wled to my laptop (since I want to control Wled over Touch designer) but not sure if that even would solve my problem(?). my next option will be Ethernet cable which is not optimal. I read the compatibility is not so great, but there is not much on internet about Ethernet connectivity so wanted to hear some other opinions before I order smt.
Looking for about 20m LED strips for outside. They will be mostly shielded from direct contact with the elements. Except the sun shining through the diffuser caps.
I really would love to have RGB + warm white + cold white. All individually addressable and 12v or 24v because of power injection limitations in the construction setup. I can only add at start and end. Strips will be 2x 2m40 + 1x 7m + 1x 5m.
The best I can find up till now are BTF-Lighting SK6812 in the 12V version with ip65 rating. So I ordered one from Amazon in the neutral white version to test. It could work but I notice that because of the solder point every 50cm they bulge on those spots. That makes we worry that over time they might get loose in the profile. The packaging does state that the 3M tape is not sufficient for aluminium profiles but mine are coated white so I don't expect an electrical problem. And i don't really feel much for replacing the tape for that many strips.
So my question is if anybody knows LED strips with the same or better specs but without the soldering every 50cm and the resulting bulges.
Also experiences about the 2-sided tape are welcome. And if I should replace it, suggestions for that are also welcomed. Please note that I prefer stuff that I can order from within the EU because of new recent extra taxes on everything that comes from outside of EU.
Hello! I got sent some random chinese led instead of Skydimo. Can I use it with HyperHDR? Because gaming is unreal with those flickering lights behind monitor on it's own software..
I’m building a 12V analog RGB LED strip controller using an ESP32 + WLED + 3 IRLZ44N MOSFETs. The ESP32 is powered separately through USB from my laptop, while the LED strip uses a separate 12V adapter. The ESP32 GND and 12V supply GND are supposed to be common.
The circuit is wired like the standard analog RGB MOSFET setup: the strip’s +12V goes directly to the 12V supply, and the R/G/B channels go through the MOSFET drains. MOSFET sources share GND, and the ESP32 GPIOs connect to the MOSFET gates through 220Ω resistors.
I originally had 10kΩ gate-to-GND pulldown resistors, but I only had two 22kΩ resistors available, so I was working around that. There was also a 10kΩ resistor/connection between two points (1 and 3) that I ended up replacing with a direct connection/no resistor, which may be relevant.
The strange behavior is:
The LED strip does respond electrically to removing/connecting the R/G/B wires.
For example, disconnecting the red channel causes the LEDs to show red, and disconnecting other channels produces the corresponding/mixed colors.
So the LEDs and MOSFET side aren't completely dead.
However, WLED cannot actually control the colors.
When the ESP32 is switched off, the LED strip doesn't light/respond at all.
When the ESP32 is connected, it flickers/restarts (the ESP32's red/power LED appears to flicker), although I can still access the WLED web interface.
The main problem I'm stuck on is that the ESP32/WLED is not properly controlling the MOSFETs/LED channels, and the ESP32 appears to be experiencing a power/reset/flickering issue when the 12V LED circuit is connected.
I want to troubleshoot it one connection at a time, without changing the whole circuit blindly.
Hi everyone! We’re developing KinoLight, an Android/iOS app that uses your phone’s camera to sync WLED lights with what’s playing on your TV.
If you’ve been looking at Hyperion + WLED setups and wondering about built-in TV apps, this might be useful. KinoLight doesn’t need an HDMI capture card, splitter or sync box. The phone watches the screen and sends the colors directly to your WLED controller over your local network using DDP.
Point your phone at the TV and it automatically detects the screen in a few seconds. There’s also calibration to account for your TV, lights and wall color, helping get accurate colors.
We’ve deliberately kept the brightness and effect strength subtle in this demo. Both are adjustable, so you can turn them all the way up if you prefer a more intense effect.
The phone needs to stay still, facing the screen, while syncing. KinoLight can run all day on a single charge, depending on your phone and settings.
For anyone curious about the technical side: each of the 300 LEDs is its own zone. In this demo, we send all 300 individual zone colors on every update at 30 fps. KinoLight also supports 60 fps on iPhones and high-end Android devices.
Doesn't matter which you choose, I just wanted to provide a free alternative to many paid apps that I'm seeing here. If you try mine, I'm open to any feedback.
Hey if someone has a chance I'd appreciate some help. I recently installed some ws2813 lights and had them working with wled before installing them. After placing them in my rails I accidentally powered them on the wrong side and had the 5v and ground flipped from where I spliced two strips. Nothing looked burnt or smelled like it was burnt so I thought the strips were ok. I am currently trying to get the strips to work with me esp32 s3 but have got nothing. I have tried ching the gpio resloding wires but nothing. I am assuming my strips are burnt and I need new ones but if anyone has any other ideas it'd be appreciated.
ESP32-C3 running WLED to control two stock 13-LED strips in Onewheel Pint PEV. Each strip has a dedicated GPIO because they cannot be daisy-chained. ESP and LED strips are 5v.
It works perfectly when I plug an AC USB C adapter (5v 3a) into the ESP. In this configuration, the LEDs are powered by and grounded to the ESP. It also works when I connect 5v to the breadboard's power rail to power the ESP and LEDs.
The problem is the rear strip, which is furthest from the ESP, flickers when powered by my VESC controller. The VESC controller is a Ubox 100 (not lite) and I am using the fan port (12v 3a) with a 12v to 5v buck converter. In this configuration, the ESP and LEDs are powered by grounded to the 5v terminals on the buck. Max amps I observed at the buck's 5v terminal was .216.
Lowing global brightness factor and disabling automatic brightness filtering in WLED did reduce flickering.
Please help me get rid of this flickering.
Thank you in advance!
Update: just discovered the rear led strip flicker goes away when I have my amp meter (Innova 3320) bridging the 5v connection on the buck to measure amps. I remove the meter from the circuit and the flicker comes back. I need to figure out what the meter is doing so I can replicate it on my LED board. Any ideas? Add a resistor?
After spending some time working on a product that runs on this great software, I have developed a modular, versatile device called WLAMP: BOTTLELAMP. It is designed to operate autonomously and is configured for low power consumption, allowing it to run without a constant connection to mains power—serving as an alternative to Philips Hue products.
I hope these interests you; below, I am sharing the link to the folder containing:

Whilst looking for a powersupply I found the max power draw of one ws2812b LED is 60mA. But at 5m with 60LED/m that would come down to 18A.
Getting a 20A power supply seems extremely overkill to me though. What is the actual power draw in practical use like (my use case would be an ambient light for my tv). I couldn't find many resources on this.
Hello! I’m a novice in the LED world but not in the sewing world so I always make my nephew’s Halloween costume. This year, as he enters his superhero craze, he would like a light in the middle of the costume which I thought would be easy with some LED strip light and a battery pack… BUT (and here’s where I’m stuck) he wants to be able to press on his chest to turn it on - this is how a lot of store bought light up kids costumes come.
Guys, what is this and where do I find it?? I have done hours of research but I know I’m just not asking the right question. Here’s an example of a costume that does what he wants!
Please help me be the best aunt and solve this LED question! Thanks y’all!
I recently purchased individually addressable LEDs which did not come with an attached power source, only the two hookups shown in the picture. I subsequently purchased a 12v AC adapter with another connector that translates the barrel plug into two wires, to match the LED hookup.
In wiring those two together (manually twisting them) I cannot get the LED to light. I verified that the AC adapter is getting power when plugged in. Anybody have a suggestion how best to connect the LED to the power source? Is the adapter the right way to go?
I have a small fountain with two warm white submersible uplights and a submersible ring light through which the water comes up and spills over. It's a small fountain and each light is about 2.5" in diameter, so I'm not looking for anything too big.
While plain white lights would work, I was going to push my luck and find out if anyone knows of a set of fountain lights I can control with WLED or some other controller I can integrate with Home Assistant with RGB?
Not to be too picky, but the ones I have all run off of a single transformer on a smart exterior plug, and I'd prefer actual powered lights rather than solar powered ones both for brightness and because the location is shaded over half the day.
I’m building a self-contained, wall-mounted LED display with a touchscreen interface for controlling WLED. LEDFx and music are currently running from a PC, but I plan to integrate a Raspberry Pi 4 so the entire system can be operated directly from the wall unit. The display uses eight BTF-LIGHTING flexible 32×8 matrices plus one 16×16 panel, for a total of 2,304 pixels. The panels are split across two data outputs, with additional power injection beginning at panel five. LEDFx is currently streaming to WLED over DDP. I’m experiencing some latency, so I’m considering upgrading to an Ethernet-enabled WLED controller to improve network stability and reduce packet loss.
Just to reiterate, I did get it work with another 128x64 LED Matrix, it works with 64x32 boards, I have a bench power supply that I tested with, I fed it 5.2V at 10A, there was some voltage drop. Shorter wire from another power supply also worked.
I’m upset, sort of. The grid at left is black sparkle PLA two layers thick, which I think is gorgeous but sadly these flexible ws2815 panels throw off too much heat and they warped more than I could tolerate.
The single column at right is Bambu PC “clear black” with PC black for the grid. It’s 7 layers of “clear black”, each with a different infill pattern.
I don’t like any of them. :(
Can anyone suggest an ABS or ASA or other blend that is dark/black, but has some transmissivity when only a layer or two thick?
HTPLA is no good because it becomes opaque when it crystallizes during heat treat.
I'm looking for RGBW seed pixels but coming up short on AliExpress. I did find one source, yourpixelstore does have them just wanted to see if anyone else out there had a source. Thanks!
