now that pivpn is eol, is this the best way to run wireguard now?
is it the best way to run wireguard now to run it in a docker container?
i was looking at a guide on how to do this, and they use a container called "WG-Easy" to "improve the experience further". is that something known/trusted?

Help python /rasberry
Hello everyone,
I need help installing the Python packages webdriver-manager and pyautogui on my Raspberry Pi. I tried using the pip install webdriver-manager and pip install pyautogui commands, but I received the following error :
error: externally-managed-environment
× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.
If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.
For more information visit http://rptl.io/venv
note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.
---------------------------
I also tried using sudo apt-get install python3-webdriver-manager and sudo apt-get install python3-pyautogui, but the packages could not be found.
My goal is to use the ChromeDriverManager modules from webdriver-manager and pyautogui in my Python code, but I'm stuck because of this installation issue.
If anyone has any ideas or suggestions for solving this problem, I would greatly appreciate your help. Thanks in advance !

How to add Picamera2 module in a venv and use it with Opencv in a Pi5
I have a raspberry Pi5 which I have struggled a fair bith with. The system python is 3.11.2 but I want to use 3.9.13 for some basic tf, opencv projects. Simple CNN stuff
The issue is managing Picamera2 module in a venv
Yesterday I pip installed it in my venv by following this tutorial:
https://forums.raspberrypi.com/viewtopic.php?t=361758#:~:text=This%20will%20create%20a%20virtual,existing%20ones%20with%20different%20versions.
however there were other issues like PyQt5 not being detected. I tried to build the modules manually with the help of GPT and Gemini. I ended up copying the file from the global python as I couldn't manually build it successfully
Now i am able to open the picamera stream using this code:
from picamera2 import Picamera2, Preview
import time
picam2 = Picamera2()
picam2.start_preview(Preview.QT) # Use Preview.QT instead of Preview.QTGL
preview_config = picam2.create_preview_configuration()
picam2.configure(preview_config)
picam2.start()
time.sleep(5)
Preview.Qt is the only way i can open it. I would like to access the data with opencv and would like to see what I can do. Unfortunately Opencv for some reason wont work with Picamera2
Any help would be appreiciated. Even if I have to start from scratch with a new venv I wouldnt mind as long as the method works

Flash Raspberry Pi OS onto NVMe SSD from a Micro SD card
I am looking for a way to format/flash my SSD for my rpi 5. I don't have a usb/ssd cord to plug into my computer, and I am hoping to be able to do something like run raspberry pi imager as a cli tool and format the ssd while it's plugged into my rpi 5.
Has anyone done this? What did you use/how did you go about it? I don't have any micro hdmi's either, so I am looking for a headless way to do this.

Which Raspberry Pi do I need to use?
Hello,
I am new to Raspberry and I would like to start working with it.
Basically I want to start learning how to use and program it (I already know how to do the electric stuff so I only need to learn the usage and programming of a Raspberry Pi).
After learning the basics I want to build a small device, which searches for traffic signs outside my car and displays them onto a small display. So I need a Raspberry Pi that is able to run the camera module and a small rgb display.
It would be great if a Raspberry Pi like the Nano or the Zero could do that, sadly I dont really know which Raspberry is made for which purpose. It would be great if someone here could help me so I know which Raspberry I need to buy?
PS: I want to program the software in Python if that would be possible.
Greetings Leander :)

MLX90640 Thermal camera breakout and Raspberry pi 4
Hi all, I'm a total noob building a raspberry pi 4 camera setup. I'm a programmer with previous (limited) raspberry pi experience.
I've been following this tutorial https://tomshaffner.github.io/PiThermalCam/#hardware-setup and I have all the listed parts. But, I don't know how to do this diagram [first image attached].
The wire [second image attached] has connections for the raspberry pi pins on one side (4 individual) but I don't have a clue what the other end is or how it could connect to the Thermal camera.
Is this something I can achieve without soldering? Do I need any extra parts? After extensive online research I'm not finding any clear step by step tutorial that goes into the hardware side of things here.
Thanks! Please @ me if anyone has any ideas 😊

The issue is that I can't seem to figure out how to compile my source code for the PI. The boot to QT option doesn't support the PI5 yet. I tryed to install QT creator on the raspberry itself but I have encountered issues. Can someone please provide some guidance, please?
