my camera module 3 won't capture videos using opencv in python
so i'm trying to make a project where i use AI to track a laser movement and put a square around the laser,but for some reason when i start initiating the camera using this line: 'cv.VideoCapture(0)' but it always says the camera is not initialized even though it works with the rpi-hello and rpi-still command just fine and it also works if i try to record a video using libcamera functions, i tried many different ways like putting this line:'cv2.VideoCapture(0, cv2.CAP_V4L2)' instead, using GSTstreamer,and i tried using the picamera library but it always said libcamera isn't installed even though libcamera functions work just fine, and i tried uisng a usb webcam and it workded just fine but i wanna use the pi camera instead. i'm very new to raspberry but i was a previos advanced arduino engineer though, so plz help

Installing Tailscale via static binary
Read online that it was possible to install Tailscale via static binary on LibreELEC; however, the tutorial assumed alot of general knowledge about the LibreELEC command system. I for one have zero experience outside the basics of the Raspi 5 OS hence why im here.
Ive followed the tutorial set by Tailscale, yet I'm still facing errors.
Tailscale Guide:
https://tailscale.com/kb/1053/install-static
#####################################
Setting up Tailscale with static binaries (unsupported)
If you would like to try Tailscale on a Linux distribution we don't yet support, we offer statically-compiled binaries on a best-effort basis.
If you use these binaries, contact us so that we can consider adding official support for your distribution.
We offer static binaries for x86 and ARM CPUs, in both 32-bit and 64-bit variants.
Download the static binaries for your CPU architecture:
Stable release track
Unstable development track
Unpack the archive: tar xvf tailscale_VERSION_ARCH.tgz
Start tailscaled: If you want to configure systemd to run tailscaled automatically, a service configuration is available in the systemd/ subdirectory of the unpacked archive.sudo tailscaled --state=tailscaled.state
Connect your machine to your Tailscale network and authenticate in your browser: sudo tailscale up
You're connected! You can find your Tailscale IPv4 address by running: tailscale ip -4
If the device you added is a server or remotely-accessed device, you may want to consider disabling key expiry to prevent the need to periodically re-authenticate.

What I've done so far,
Enabled Raspi Tools in the LibreELEC add-ons
wget https://pkgs.tailscale.com/stable/tailscale_1.74.1_arm64.tgz
tar xvf tailscale_1.74.1_arm64.tgz
tailscaled --state=tailscaled.state
r/raspberry_pi - Installing Tailscale via static binary
Error = -sh: tailscaled: not found
I tried
./tailscale_1.74.1_arm64/tailscaled
r/raspberry_pi - Installing Tailscale via static binary
I proceed to get the error that tailscale has stoped.
What am I doing wrong/ can anyone help me get to my goal.
Have in mind that I am somewhat new to this system and the raspi 5 as a whole

Failed to attach to default card (Headphone audio problem on retropie)
Hey Guys,
I just build a arcade bartop but I came across a issue that includes the audio.
The HDMI Audio worked fine but its understandable, that I didnt want the very low volume from the monitor i'm using in my build.
For this problem I bought a speaker with a AUX (Headphone Jack 3.5mm connection), which will not work. I set the setting to use Headphone on Raspi-config and Audio settings. I also set the following commands in the config.txt file:
(This line should already be in the file, but if it's not then make sure to add it)
dtparam=audio=on
(Pretends no audio formats are supported by HDMI display, forcing all sound out the 3.5mm headphone jack.)
hdmi_ignore_edid_audio=1
As i tried to fix it i came across the error:
VolumeControl::init() - Failed to attach to default card!
AudioManager Error - Unable to open SDL audio: ALSA: Couldn't open audio device: No such file or directory
I'm using the newest retropie version for the Raspberry Pi 4 4GB
I would be very glad if someone could help me, because i've searched the internet for many hours and tried stuff with no success 😦

V4l2 rtspserver
does anyone how to resolve of installing the v4l2rtspserver?
Basically, I'm planning an senior design project of using the VS creator software for inspecting products and I called the company if I can use other cameras. They told me no but one of their engineers told me I could use a raspberry pi to act as a bridge of using the other camera to the software.
I'm currently having trouble right now of using the terminal to getting into the github's password since they are not implement the password authentication no more. I already have the account and everything(repository, personal token code?) It's just I dont ways around in coding wise in here. (I'm an electrical engineering student btw)

Screen Recording on Raspberry Pi 4B
ok so I'm having trouble with screen recording. I tried 3 softwares (vokoscreenNG, Kazam, and SimpleScreenRecorder) and each has their own problem
vokoscreen: I can't record Audio , for some reason it cannot read my microphone, but my raspberry pi can read it
kazam: When I hit record, it does record video and audio(i check pulse and it is recording), however the icon to stop its recording does not pop up on the tray so i cant finish the recording. If i force stop the recording, the video file would not play.
simplescreenrecorder: this one do record my audio very clear at that, as well as my cursor. However it does not record my screen, it literally only records my cursor moving.
can anyone please helpppp!

MicroPico terminal issue
Morning! This is a question which i find very hard to know where to find the answer to.. but here we go:
I use a Raspberry Pi Pico with MicroPython, and vs code as my IDE with the extension MicroPico which works mostly fine!
My issue is that when I run a code on my RPP MicroPico opens up a new terminal of its own and that terminal seems to have encoding issues.
I want to use my normal Powershell-profile for my MicroPython-shell, this might be much to ask though, but at least it should be proper UTF-8 encoding in the terminal that MicroPico use.
Im sorry if this is the wrong forum, im a beginner and I didnt know exactly where to turn.

i can t connect my raspberry pi zero w 2 to my wifi
The first time i flashed the OS in my micro sd card using raspberry image, i flashed the Raspberry Pi OS(32-bit) becouse im using the v2 camera, and i changed the defoult settings, i enabled the shh and the wifi setting the name and the password(I checked it, it's correct and my wifi is 2.4ghz and 5ghz), then i put my micro sd in the raspberry but it doesn't connect.
The second time i flashed the OS in the same way but i didn't modify the settings and i just added the ssh file(without exentions)and the file for the information of wifi, i insert IT(Im from italy), my wife name and password(the file was conf) and also this second time didn't work.
The third time i used etcher for flashing directly the OS in my micro sd card and i added shh file and the conf file, but also this third time it didn't work.
All three times i connect my raspberry to my laptop using my micro-usb cable and i waited for the booting and all the three times i formatted the micro sd card
can someone help me please???

Multiple keystroke on button press
I'm using the Raspberry Pi Zero 2W and I want to know if it is possible to use the dtoverlay to simulate multiple keystroke with only one Gpio?
I want to send Ctrl+C by pressing a single button but I had no luck with dtoverlay. I thought that I could do the same thing with python, a daemon-like script that simulate the keystroke when the two gpio are down, but I don't know how to simulate keystroke on the console (no X11 or Wayland)

sensors miniproject help
Hello,
As part of my sensors class in college, I have to do a miniproject, my group is doing a landmine detection system,
Here are the details:
We plan to use a custom metal detector as the primary sensing element, that will be mounted above a model field (simulating a drone essectially) a camera module will capture an image of the field and create a coordinate system, then a directional metal detector will find potential landmine locations and map them to the picture taken, then the system should display a list of coordinates
This is the plan anyway, we have 5 weeks till the submission, I got a rasberry pi 4b 1gb from a senior for cheap and we plan to use that as a microcontroller, the other teams aldready have a head start on us, so I would appreciate any help on this project, it's my first time working with a microcontroller so I don't know how to do the connections properly or whatever, im not sure whether all the computation can be done with the rasberrry pi or if I will need any other components, I would also Appreciate any feedback or recommendations for the project
