Good day, I have a Raspberry Pi 4b which I shelved for a couple of months. I tried booting it today and it won't let me log into my desktop. After supplying the password, the monitor just turns black for a couple of seconds then reverts back to the login page again. The weird thing is that I...

Hi everyone, Im trying to build a project using a Pi motherboard and connecting to it on Windows 10 via SSH but I ran into some problems. First I tried to connect using Command Prompt but it doesnt work for some reason and Im gonna post the errors. So the error im running into in Command prompt...

It has happened a couple of times now, usually, if I restore the backup to sdcard it starts working again until it randomly gets bricked again ? I thought it was because of heat so I installed a fan that keeps temps under 50c on idle, and 60c on load. I don't have a mini HDMI cable, but all...

Hi, I recently set up a VPN on my Raspberry Pi so I can access my files on the go anywhere. I port forwarded ports (UDP) 500 & 4500 on my Pi and installed a profile on my phone so that only my phone can connect through to the VPN (pistrong). I'm not too concerned about security there as it's...

I recently set up Samba on my Pi 4 and plan to have it run 24/7 as a NAS device. Am I advised to do so or is it not safe as it'll degrade the Pi over time? I have adequate cooling on my Pi with a good heatsink+fan (idling around 27 degrees C) and though I did actually follow a guide to...

Hello, I have raspberry pi 4 4GB with Raspbian 64bit. Up to date. I cant port forward port 25565. Every single time I check port with website yougetsignal.com, canyouseeme.org etc. Port is showing as closed (Connection time out). I disabled firewall and still closed, enabled firewall on...

So I am really wanting to know if it is possible to do the following: I am wanting to set up Pi-Hole (adblocking through DNS filtering) on my home network by pointing my router to the DNS server and filter I created on the Raspberry Pi with the capabilities of also having my family members who...

Currently I'm trying to connect my rp4 to my windows 10 share file but I'm running into quite a few issues. I want to say too that I'm quite a novice when it comes to non-windows based machines so there may be some errors in my operation that I'm unable to see. Okay so I followed this guide...

Hello all. I am currently doing a project that is trying to determine how useful a personal cloud storage device would be for a business compared to using options such as Onedrive (as well as how economically viable it would be). As part of this project, I need to determine which would be the...

For all things backup and archiving photos, and videos, I have had an external harddrive of 4 TB USB 3.0 that needs to be plugged into the wall for power. I have been using this for over 5 years now. I am concern about its lifespan and uncertain when it will begin to fail on me -- if it did, it...

Hi Guys Can you please tell me if this idea is possible to do on a school project. I am using a SENSE HAT and Pi Camera. What I want the code to do is say if the temperature is 35 degrees, it will take a picture every 30 seconds for 2 minutes. But I want the image taken every 30 seconds be...

Hi, I'm currently setting up my Raspberry Pi 4 Model B 4GB to be usable as a NAS. To do this I'm thinking of connecting a WD Red 2TB HDD (256MB cache) to the Raspberry Pi using a USB 3.0 to SATA III adapter. The HDD uses a SATA 15-Pin Power Connector Pinout. I can directly connect the Raspberry...

Hi, I want to build a pseudo laptop with a pi 4 and a display panel, but don't want to have to deal with powering them separately. If there is something that I can get to have an input from a battery and two 3 amp outputs to power both the Pi and Display, what would I be looking for? I couldn't...

The Raspberry Pi 4 network speed I am getting is 645Mbps connected via Ethernet cable using speedtest from command line. I'm getting 950Mbps on my laptop with similar wired connection through switch/router. I expected the Pi 4 to have similar speeds of 1Gbps. What are the variables...
