USB Capture - Error Code 19 - Powering off LEDs

So for the second time in this thread I’ll call this fixed!!! I felt good about it when I plugged in the new supply and got a stable 5.4V on the 5V pin. As I plugged in my grabber it dropped to around 5.25-5.3V whereas when I tested with the old setups it was very close to 5V or slightly under so I imagine it was undervolting with that kind of voltage drop.

I don’t expect this $10 power brick to last very long, if it goes I’ll order the suggested one before, but for now it has 100% fixed my issues. Thanks all for the help!!

no problem, its also possible to use a ATX PSU from a computer. They deliver a solid DC in 3.3 / 5.0 / 12 volts.
but they are big and huge, thats why most people go for a much smaller ( but still as good) Meanwell PSU

So as expected that Pi PSU I ordered didn't work very long. I made it successfully through one two hour movie before it started shutting off the grabber again so I ordered the Meanwell PSU you suggested. Now Im wondering how I should go about hooking it up with USB-C, should I use my sacrificial USB-C cable w/ only +/- and add additional grounds to the Pi?

connect it the same as now, but if possible lower the voltage down to approx 5 volts under load.
Ground everything to everything and you should be fine

Well with my current setup I was using a USB brick that was all integrated for USB Type-C, I realized this morning that won't be possible to use a regular USB-C cable with the meanwell. This was what I'm currently using:

this PSU broke so fast you mean? its looks like a good option for the PI4

It was by far the best of the methods I have tried which included the following:

This is what I started with:
I also used an iPad 5V/2.4A charging brick
I also used this to power via pins which is primarily powering my nodemcu & LEDs:
Now I'm using the Pi4 one I linked above but it still drops the grabber at random intervals, there are no undervoltage warnings in dmesg anymore but it's got to be a voltage regulation issue as it's doing the same thing as before just not as often. I can keep the grabber on for about 20-30 mins at a time now instead of 2 minutes but still not the reliability I'm hoping for.

it looks to me like the PSU or PSU's is not the culpable anymore. Can you switch in Hyperion.NG the setting from device0 to camera?

i had somebody here on the forum also with this loop grabber and for kind of daft reason Hyperion and RPI sees this as a camera

indeed! Lol I've never had /dev0 only Camera 1 but I've always left that to Automatic.

make it a full static setting then (nothing on automatic) and reboot the RPI,

Choosing Camera 1 vs automatic?

Zitat von jeroen warmerdam

make it a full static setting then (nothing on automatic) and reboot the RPI,

Current settings now, I get 5.35V still on the 5V pin with the grabber connected but not under any load at all.
