Het lijkt erop dat er iets fout is gegaan bij het solderen. Ik heb met mijn spanning zoeker gekeken of alles spanning had en dat leek goed, maar een kabel raakte los. Daarna heb gisteren alles losgehaald, opnieuw gestript en weer vast gesoldeerd. Het werkt sindsdien zonder problemen dus ik denk dat het nu opgelost is. Heel erg bedankt voor je hulp Ambientheater77!!

Ik heb vandaag eindelijk je fixes kunnen proberen @Lightning-guy77. De leds knipperen nog steeds. Ik heb het volgende gedaan:

1. de +5 volt van het einde van de ledstrip samengevoegd met de +5 van het begin.

2. de GND van het einde van de ledstrip samengevoegd met de GND van het begin.

3. de GND van het einde van de ledstrip verbonden met een grond pinnetje van de RPi (op basis van de link die je deelde).

4. de GND van het begin van de ledstrip verbonden met een ander grond pinnetje van de RPi.

Zie je dat er iets in deze stappen mist of verkeerd is?

Zitat von Lightning-guy77

so: GND connected together at beginning and end.

+5 volts connected together at beginning and end.

Thank you for the great information you provide. I promise next time I will ask you in Dutch but I hope that other people also learn from my mistakes and your answers.

Below you can see an image of my wiring. In blue the beginning of the led and in green the end. The green wire is already connected to the power supply. So you are saying that I should add one wire to the yellow dot and one to the red dot and combine these with the wiring from the beginning of the leds?

Possibly another not so bright question, you mentioned two power supplies but with that you mean one for powering the leds and one for powering the RPi, right?

I unfortunately don't have any tools to measure volts as I normally try to stay away from hardware related stuff. I should probably buy something for that. Do you have a link to something suitable?

Currently, Hyperion version 2.0.13~bullseye is installed. There are 205 leds in my setup. The RPi with Hyperion on it works fine. I can still access the web app. On the web app, I can see that the capturing device is still functioning properly. It really seems that that issue is resolved now I powered my RPi separately. However, it would be nice to have both the leds and video capturing working

After plugging in the leds (yes, I really forgot that...), they started flickering. I still see that the capturing device is working, however, when I turn the led output on via Hyperion, the flickering begins. Any thoughts?

Thanks for responding! The grabber works fine when I connect it to my laptop so that should be fine. Currently, both the RPi and the leds are powered with the same power supply. The RPi via the USB port and if I understood correctly only one of the two ports can be used to power the RPi. When I try to power the RPi separately, the video capture seems to work a lot longer (currently longer than 20 minutes which is a new record). However, now the leds don't turn on anymore... I'm using this power supply.

Again, I'm quite the RPi hardware noob so thanks for the help.

Hello,

Almost a year ago, I setup a Raspberry Pi Zero 2 W with Hyperion that controls the leds that I attached to the back of my TV. It worked fine for a couple of months, however, it stopped working after a while. Afterward, every time I tried to boot the RPi it worked for a couple of minutes but then the capture device stopped. I read a lot of the threads of other people that face the same issue as me but every proposed solution doesn't work for me. I tried to replace all of the parts of my setup (except the RPi). I also installed the same setup with exactly the same parts on another TV but that has been working without any issues for over 9 months.

The error that occurs is as follows:

My setup:

1. Raspberry PI Zero 2 W
2. WS2812B LED Strip - my setup uses 205 leds in total
3. Video capture USB stick
4. Power supply 40 Watt - 5V / 8A

I have always been more software oriented so I have little experience with the hardware side of RPis. I really hope someone can help me with fixing this issue.

Thank you in advance.
