my L298N motor driver isn't working with pi 5
Hi,i'm new to this server.
so i'm making a project that requires 2 motors to move.so i decided to use 2 hobby gear motors and an l298n to control them, i also connected them to 3 18650 li-ion battery's. all good so far, but when i tried controlling them, nothing happened. so i tried a few things to do:
1:check the wiring multiple times
2:check the code multiple times
3:i tried adding a heat sink but it didn't work
4:tried directly giving commands to it using the terminal instead of code
5:tried using 2 18650 battery's because it worked a long time ago with 2 battery's but now it didn't work, even if it did work it was slow
6: i tried using an external 5v regulator because i had a suspicion that the internal 5v regulator wasn't working but it still changed nothing
7: tried using another driver like the l293d but it still didn't work
8:tried connecting the motor directly to the power supply and it did work so it's not the motor or the battery's that are broken
and some other minor stuff like switching jumper wires and things. but non worked. this is the code(the code is for testing just one motor) and i posted an image of the whole thing too(i know the image isn't very clear cause i have messy wiring). i also just wanted to point out that buying other components is like the last resort, so don't go in and say"just buy a new driver or something", i would appreciate any help possible,
Omar.

Connecting RPi cam v1 with CM4 using waveshare Nano baseboard (CM4-NANO-A)
I am trying to connect my Pi cam (ov5647) with CM4 and waveshare nano baseboard. I updated the config file by adding following lines in the end:
dtoverlay=ov5647,cam0 gpu_mem=128 start_x=1Libcamera commands are working perfectly but the ffmpeg commands are giving errors. I listed my camera devices and /dev/video0 is listed under unicam. Here it is:
bcm2835-codec-decode (platform:bcm2835-codec):
/dev/video10
/dev/video11
/dev/video12
/dev/video18

unicam (platform:fe800000.csi):

Here is the ffmpeg error:

Ps: I am really a newbie with RPi so really sorry for any mistakes and kindly let me know if any other config details are needed to debug my error.

Permission problem to launch my bot in my venv
Hello I recently took a Raspberry Pi 5 to put a Discord bot in python the problem is that I struggle to use it. for example when I put the bot on my user (not root) I create my venv, I install the modules in the requirements but as soon as I launch the bot it gives me a python error that I do not have the necessary permissions etc ...
Nothing to do but even when I do sudo su I still can not access the root folder

Connecting 3.5” ST7796 as main display
Hi, I’m sick of trying to connect a 3.5 inch display to Raspberry Pi zero 2…
I was tryin like in this repo:
https://github.com/jobitjoseph/fbcp-ST7796
but errors on every possible steps.
Have you guys any tips how to connect it as a main display? It’s a cheap screen from AliExpress, I can find link.
For example on esp32 simple codes works perfectly, I know it is completely different thing

Raspberry Pi 3B Boot Loop Issue
System Details:
Model: Raspberry Pi 3B
Operating Systems Tried: Raspberry Pi Lite & Full OS (Official Raspberry Pi OS images)
SD Card: 128GB microSD (integrity verified)
Power Supply: Official 5V supply (used previously without issues)
Symptoms:
Pi hangs at the “done.” message and then restarts after about 10 seconds.
RGB display shows rapid, alternating green and red flashes.
Boot log shows USB device events (e.g., “new high-speed USB device found”) even when no USB peripherals are attached.
Issue occurs regardless of attached peripherals (ethernet, keyboard, or none).
Recent Changes:
WiFi configuration updated via raspi‑config.
WiFi Country Code: Set to “UK” (should be “GB” for the United Kingdom).
Boot loop began after making this configuration change.
Troubleshooting Steps Already Taken:
Tried multiple OS images and repeatedly wiped/reflashed the SD card.
Tested with different peripheral setups (with and without ethernet/keyboard/display).
Verified SD card integrity and power supply consistency.
No explicit error messages besides the continuous reboot loop.
Current issue:
The Pi won’t fully boot, preventing access to raspi‑config to correct the WiFi country code.
Need guidance on modifying the configuration offline or other workarounds to resolve the boot loop.

Internal Network Domain Problem (Apache2, Pi-hole)
Hey, I am hosting a website and Pi-hole on my Raspberry Pi. The website is accessible to anyone on the internet and operates correctly; however, for some reason, I cannot access it locally. Within the LAN, it seems to work intermittently, and I cannot access it at all over Wi-Fi. The browser displays a 'connection timed out' error. The Raspberry Pi is correctly registered as a DHCP server in the router. Unfortunately, I have tried various solutions and still do not know what the issue could be.

Specific Boot Failure from SSD on Raspberry Pi 5 with Radxa Penta SATA Hat – SDRAM Error
Hey everyone,
I've been troubleshooting an issue with my Raspberry Pi 5 (8GB) using a Radxa Penta SATA Hat and four SSDs (one for boot, the rest for NAS storage). I'm trying to boot from the SSD, but I'm getting 8 flashes on the RPi, indicating an SDRAM error (firmware issue or SDRAM damage).
I've set the boot order correctly using a micro SD card, and everything works fine that way. However, when I remove the micro SD card and try to boot from the SSD (with Raspberry Pi OS Lite already configured and SSH enabled), I hit this error.
Any ideas on how to resolve this? Thanks in advance for your help

Apache2 server won't expose to internet
Hey there, so I've been trying to setup a simple webpage using apache2. I've been able to set it up so I can connect to it through local ip, but if I search for my public ip I don't get the webpage.
I've already setup the needed port forwarding of port 80 to the static ip of the raspberry pi and configured the ufw of to allow 80/tcp Anywhere.
I'm kinda lost here, I've previously setup my raspberry pi (same static ip) to have a public webpage, that worked but I wanted to restart and now it doesn't work (so I would think it's not a problem with port forwarding)
Do you guys have any idea of what to try?
