Raspberry PI4 as NAS and media player
Hello! I was wondering if someone might have some suggestions or advice.
I want to use my raspberry pi 4 as a NAS as well as it being able to play videos itself.
I've added a schematic of the situation. It would be great if I could put videos from my pcs and laptop to the External SSD making it able to play those files directly from the pi to the projector, but also my samsung tv to be able to play video files from the SSD attached to the Pi. I know that last thing is possible, because I've had it working before, by setting up a specific kind of NAS that the smart tv read as a media source, but I don't know if I can also add the possiblity for the pi to just be used as a media player and play the files from the external ssd attached to it. Preferably also while controlling the pi's media player by either the PC or my smart phone.
Hope my question is clear 🙂 Any advice or suggestions are appreciated. Thanks in advance!

Pi Camera Breaks
Hi,
I have a raspberry pi 4 and I am trying to connect a Camera Module 3 to the board. The Camera will work for a while, and then will stop working and will be bricked. The only time that I can see it happened right after I did a specific thing was when I installed some python libraries onto the pi. The only libraries that would interact with the camera were opencv and picamera2. This happened a few other times on some other boards, and they would just brick randomly and not work again. To test the cameras, I use libcamera-hello, and it says that there is no camera that is connected to the pi, when the camera is obviously plugged in. Does anyone have any ideas? I have run sudo apt-get update and upgrade, and that didn't fix anything.

Best way to do moving graphics
What would be the best way to display something like this? the red dot in the middle moves around rapidly, and the numbers change rapidly. Would C# or Python be better? And what package should i use?

Pi Zero 2 just craps out.
Hello,
My new Rpi Zero 2 just... Dies over network.
The light is on saying it has activity, but I cant SSH into it, and the mediatmx server running on it becomes unresponsive.
It seems to happen faster if I unplug it, and then immediately plug it back in, and slower if I let it wait - which makes me think it's temperature, but I have a heatsink on it.
I can't even ssh in to fix or reboot it.

How to use HID on arduino Mega2560
So basically im doing a school project and im doing a button box, for that i bought the arduino mega because it has more ports. I searched for a while to see like how would i do it, so basically only the arduino leonardo and the mini can use HID so when you connect the arduino to your pc it will recognize it as a keyboard or a gamepad. But the mega doesn't have HID so i saw on reddit a lot of guys using an app called Flip to change the firmware of the atmega16u2 chip so it works as an HID device. But im running into some problems, i already have the hex file but when i try to open a connection usb on the app it says that some .dll are missing and i installed the dll that was missing but i had the some problem still. Then i saw someone again on reddit saying that you need to put the arduino on DFU mode so the app can access the firmware, ive done that too but i think that my aduino is not going into DFU mode.
when i try to put my arduino in DFU mode it shows like this on device manager
i linked 2 photos the one called "1" is how i should show and the one called "image" is how it shows even after i put it on DFU mode.

"Playback of protected content is not enabled" error - Spotify
When I try to listen to Spotify on either Chromium or Firefox it gives me a message saying "Playback of protected content is not enabled" however all of the troubleshooting tips that I've tried (including contacting Spotify) haven't worked.

Raspberry Pi power LED blinking
Hi, i have this Raspberry pi 4 2GB since 2020 and few months ago the pi randomly shut off and wouldn't work after that. I tried searching it online (I found that it is some problem with power like short or the power chip failed) after that I didn't want to deal with it at the moment soo i kinda forgot about it. But now i kinda want it to work, could someone help me?
Here's what i kinda got from it:
When i plug it with the offical rpi brick it just blinks red
I tried switching power bricks, i tried my phone charger (which can do 5V 3A) and for some reason the blinks are more dimmed and less frequent. I include videos of the blinks on the offical brick and my (the black cable is the offical)
Anyone know how to fix it?

Libary Adafruit not found
Hello there I am a second semester physics student. We want to build a weatherstation equipped with a few sensors. I am new to the raspberry pi programming stuff. I have a code that should read the sensors and create a csv table. Once i try to run it with the sensors on the raspberry i get the following: No modul named AdafruitBMP. (It refers to import AdafruitBMP.BMP280) I know that that means adafruit is not installed, yet i dont find a way to install it. Until now ive gone throught numerous websites to find a solution but none seems to work. Note: Not all of my code is written by me a small portion is made by chatgpt so i dont understand everything the code does but most of it is made by me.

Pressure Sensor for Pi 4
Hi, Im working on a project and i have more experience with software programming than physical anything. basically i have a pi 4 and i need to add a sensor to it that you can attach a tube with a balloon on the other end and have the sensor read the pressure changes.
Does anyone have an ideas or sensors that could be used for this? I would ideally like to use the ic2 bus on the board but if i need to get an adp? that can be done too.
Thank you!

5V out on ESP32
Hey!
I know this is a raspberry pi server but I didn't know any other place to ask.
I have an ESP32-WROOM-32 and it seems to only have a 3.3v output and i need a 5v out to power my lcd,
i've found that connecting it to the VIN pin gives me the 5v that i need but is that okay to do since its supposed to be the input?
Thanks in advance.
