Pihole & IPv6
Good afternoon,
I have a Pihole on my home server. For some reason I am not able to use IPv6 on the Internet despite my ISP providing it. How can I troubleshoot this? I'm a bit weak on the network commands to check.
Thanks in advance!

Can't connect wifi dongle to rpi 3b v1.2 for repeater project
Hello, I've been following this guide: https://hackaday.io/project/171296-truly-wifi-extender
to turn my pi into a wifi repeater for a small project. However, after following all the steps i noticed that my usb dongle won't even connect to anything when it's plugged into my pi. Only my pi is connected to my home network, so i can't test if the project works. The pi recognizes that the dongle is plugged in when i type lsusb in the command line and the dongle does work when i plug into my laptop. Any help is appreciated.

Setting up an ethernet connection for VNC (Pi B+)
I'm trying to set up VNC over an ethernet connection, using several tutorials I found online. I have an Ethernet cable running from my laptop to the pi, and I want to be able to control the pi via VNC from my laptop.
I've enabled wifi sharing on my laptop, and I have the cable running, but the Pi isn't connected -- the up/down networking arrows are flashing. The frustrating thing is that it was working only an hour ago, and I was able to both ping google.com from the pi and connect to it via VNC. Now it is not connected to the Internet and I cannot connect to it by VNC. The only thing I did was set the pi to have a static local IP, and reboot it.

Raspberry pi 0W WIFI stopped working properly
I Turned off the raspberry pi by unplugging the cable( i didnt know that i have to turn it off first) and i ended up with a fried sd card and the wifi got super slow it was downloading at 1,2ish MB/s now its 80Kb/s at best. Any Ideas on how to fix this and thank you!

How do i connect THIS LCD screen, no touch
I'm trying to use an old display from a Portable DVD player (used in cars). The display is a 7" 0004-JXY-A1 from Hannstar. It uses the same flatcable as the rasberryPi Camera so i thought maybe i could use this screen? Well i have some pictures attached to help you guys understand but when connecting the screen i ofc don't get an image. I need drivers or i think i could solder the screen to some pins, any ideas would be great. I do have another screen but rn i could not buy anything so i'm looking into doing it without buying other material.

Raspberry Pi 4B experiencing slowdowns
Hello, I've finished setting up my Raspberry Pi 4B and I'm noticing quite a lot of slowdowns. For example: if I want to open a window it can take quite long to open, especially compared to a PC OS (ik I shouldn't really compare, but still). Is there any way to maybe increase the speed? Am I maybe missing something? I'd appreciate help.

motor urgent help
So i set up my pi 4b, with my monitor and I connected it to a PCA9685 . I have 6motors but wanted to test only of them and i couldn’t figure it out. I have a 5V adapter for the pi and a 12v 5A adapter for the PCA9685 that will attach all of my motors. The max stall current on my motors is 2.3 A at 7.4 V. Ive also thoroughly checked all my connections as well as confirm that I2C connection was being read by my pi. Does anyone know what else i could do?

Connect multiple SATA HDD to a RPI 5
I'm looking for ossible options to connect 4-10 SATA HDD's to my pi, preferrably energy efficient.
So far, I have tried external USB enclosures that are connected via USB3, but they all seem to draw more power then the RPI itself.
Now, I was thinking of connecting my Pi directly to the PSU of an ATX case I have and connect the HDD's via the PSU's SATA-power connectors.
The only thing left is connecting the data-sata cables to the pi.
One option would be an nvme hat and one of these https://mobspares.com/en-eu/products/m2-m-eky-pcie-3-0-to-sata-6g-adapter .
Does anyone have experience with this?

Ethernet soldering pcb
For a project I want to directly connect ethernet wires to the pcb of my switch by soldering them on. However I have no idea which color should go where. When I connect a multi meter to one pin on the inside of the rj45 jack, multiple of the ‘soldered’ connectors make a beep sound. Is there any documentation/guides about this? I can’t find anything

Work project, trying to figure out what steps to take
I took a new job for an agricultural company, but something unexpected came up that they want to develop. I'm trying to figure out if I need a Pi, and if so, the best steps to take to see the project to fruition.
In agriculture, there's big silos that store grain. People have developed expensive systems to monitor that grain through large cables secured inside the bin. The cables are built of a string of sensors that measure temperature and moisture. The first picture is an example of the cable. Inside that green shroud, is a wire with these sensors on it every 4 feet. Each sensor has it's own serial number, and returns information regarding moisture and temperature. They are read through an app for diagnostic purposes - pictured in image 3, or are relayed every 66 minutes via cellular data to a cloud service that lets a customer read the data on the website or phone app.
Those cables (sometimes a single cable, sometimes up to 6 or 8 daisy chained together depending on the size of the silo) connect to the board in the last image. That board has a two pin output that plugs into a device (image 5) you connect to via bluetooth on your phone that lets you see the information from the cables.
The purpose of the system is to set a temperature and moisture range, and the system warns you if the grain falls outside those parameters.
What my boss wants is a simpler system. One that runs off an Arduino or Raspberry Pi, that constantly monitors the temperature/moisture signals, but is connected to three LED lights to give a visual indication of the condition of the grain. Green means OK, Yellow means rising/danger, Red means check the grain.
So basically the simple system would be Sensor cables > Raspberry Pi > Lights. Temperature and moisture range would be programmed via a bluetooth connection on a phone app. What I'm wondering, is where do I start with this? Arduino or Pi? Maybe online resources that would give me a crash course.
Thanks for any input or help!

pi400 hyperpixel installs et cetera.
So as of last night, the images supplied by raspberrypi imager for the 64bit are broken apparently.
Imagery is failing to config user, hostname, ssh, wifi, regional settings like keyboard, wifi region, etc.
Also, the config.txt install for pimoroni screens and some other displays are now broken.
Was this accidental or on purpose?
And does anyone know if raspi' has previous versions posted anywhere so that I can pull down something pre-break before it's gone?

Is a Pi Zero 2W enough for my project?
Hello, I want do build a device with a display on which some stats (for example current speed and more) are shown for a car driver, is a Pi Zero 2W enough to power a display, some sensor modules (f.e. gps module, temperature sensor) and let a small code run on it?

NodeJS site on a Raspberry Pi 5
I have a Raspberry pi 4 and 5.
I ran my site on my pi 4, github: https://github.com/maxwalks/ChatApp
everything ran fine, no problem at all. I use pm2 so i can access it with local ip
I did the exact same on my raspberry pi 5 and the website loads once and when trying to reconnect it just doesnt work. I will link a video.
I also tried using ubuntu server instead of debian. Same result.
Keep in mind when using localhost the website works fine on my pi 5, just not when using something like nginx or pm2 to be able to connect it outside of the device.
in the first video it is running on my raspberry pi 5, not working.
in the second video is another server running Ubuntu Server, did the exact same yet it works on this server but not on a raspberry pi 5.

(Yes, you can know the public ip i will probably delete the server anyways)
