I have a headless RaspberryPi Zero W that I wish to use as a server for remote printing so my neighbours and myself can have a common printer. The printer unfortunately is an HP LaserJet 1020 - the one my neighbour has happily given to me. But setting it up as a remote printer has been a horrible experience for me.

I'll write down a few of the commands I have tried to get it to work.

First I made sure that the laptop is connected to the laptop with the command :

lsusb

When I could see the HP printer I proceeded with:

sudo apt install cups hplips printer-driver-foo2zjs printer-driver-foo2zjs-common printer-driver-foo2zjs

From my laptop browser, I went to <my.ipv4.address>:631 and added the HP printer. Selected the driver. Checked the Shared Printer option.

Now, I rebooted the pi, re connected the printer, and tried to print something via my Linux Mint laptop. no luck

Then, I read around and found that I need to run the command:

sudo hp-setup

So, I ssh'ed back into the pi and tried to run this command and the entire pi crashed.

Has anyone managed to get this darn machine working nicely?

We're all Linux users, so I don't need to install samba and all that.

Actual working projects, not PoC.

I am thinking of

  1. laser trip/motion detection on windows/doors with Wifi/LAN/LTE

  2. Door Camera with motion detection and NVR

This has been on my mind alot, but im pretty lonely and depressed to say, i have family members but they dont like what i enjoy like we cant relate to each other usually. I want to make a robot someday that you can play games with, like it can press keys on a keyboard and move a mouse, that type of stuff? The concept seems hard and pricey for someone like me.

Would something like this even be possible in real life? or is it just another dream?

Would it be cheating if im lonely? i feel like this could possibly help people such as myself or people who are disabled in some way.

Hey Folks,

I got a new tv through some family and wondering whether the raspberry pi 5 is suitable for connecting to it for general streaming and video.

I've seen a lot of mixed things on this but the other discussions on this topic seem to focus on quite technical stuff about media home servers and media codecs and so I'm not sure whether these are complicating the matter more. For a basic starting point, is it feasible to just get a pi 5 8gb to watch youtube, other streaming and file playback? The tv is capable of 4k but I'm not hugely bothered if I'd need to lower the resolution.

Because I'm currently using a zombie 2009 imac with mint on it as a tv so the bar is extremely low for quality and stuttering, but it tries its best and having a desktop environment where i can get ublock and control with a ps4 controller has been far more my thing than having to deal with smart tv constrictions.

I don't mind a bit of a project to play around with, but if it'd be more hassle than its worth with where the Pi is at do let me know.

Im currently making a costum 10x10 led matrix, and for it to be able to display senseable stuff, im trying to segment the display into 10 vertical lines which cycle at at least 100hz. Would a Python script on a raspberry pi be able to cycle its GPIO pins at this speed? Or Would an arduino or other Microcontroller be able to do it better?

"The current pressure on memory prices, driven by competition from the AI infrastructure roll-out, is painful but ultimately temporary," CEO Eben Upton wrote in a blog post. He also said that the company looks forward to "unwinding these price increases once it abates."

Going kind of crazy thinking about the options. I'm ultimately trying to get a stable media server running on my 4B (no transcoding) and I think I'm having power issues.

I had an externally powered NVMe enclosure but I stopped using it mainly because the enclosure wouldn't turn itself back on after a power surge. I switched to a 2.5 SSD with an unpowered adapter cable but occasionally the drive gets disconnected (guessing it's power issues). I would like to use the NVMe drives since I can easily fit the SSD into my desktop (ran out of NVMe slots). It would also be good if I had a solution that supported hardware RAID 1.

Hello! I've done some troubleshooting on this and i feel like I'm going crazy.

I have a pi 3 B that I got for cheap at a garage sale a while back. It was still in its original packaging - practically brand new. Got around to setting it up yesterday morning and installing raspbian. So far, all good. It boots into Raspbian without issue.

Once in, I connect to the internet and run "sudo apt-get update". The mirrors all 404.

So to make sure I actually have internet, I ping google. No issues there; pings successful.

I try to navigate to raspbian.org on my phone. The website gives me a 502 bad gateway nginx error. So I assume the mirrors are down, but decide to check social media... And nobody is talking about it? Anywhere?

Is raspbian.org not a legitimate website? When I run the update, it seems like its trying to pull from mirrordirector.raspbian.org so I assume so.

So. My questions:

  • I've done a lot of googling on updating my mirrors, and have found relatively little. Does raspbian not have an automated mirrors updating tool?
  • Is raspbian.org not a legitimate website? If it is, why is nobody talking about it being down? Its been dearly 24 hours. It this regular maintenance?

EDIT:

Turns out the version of raspbian on the SD card this thing came with was so old it just couldn't update lol. Still have no idea what's going on with raspbian.org though lmao

hi, if anyone have those boards, can you please share what score do you get on them - in google octane and mozilla kraken?

I heard varying things, I expect to have like 6-8 people come over in a few weeks and I want to set up lancache.net, but performance wise would it be horrible on a raspberrypi 4? or decent? I heard many things about lancache support on the raspberrypi, so I would like to hear about that too.

I do have a intelnuc as a secondary server but it would be harder to set up lancache on that, also I think I need to get a wifi card to set up a AP network, so would it make significant difference for a 16gb ram and modernish intel cpu to run it?

I made this binary clock as a count down timer for my last day at work.

I used a RPi Pico W with a LED RGB matrix.

As the Pico doesn't have a real time I used the WiFi to get the current time and date.

I have beat my head against the wall on the Raspberry pi forums for hours on this, but I am shocked to find nothing that makes sense.

I KNOW that in Stretch the Raspberry Pi 3B+ is COMPLETELY capable of playing 1080p mp4 with ZERO issues on VLC, because I used it as my media machine for YEARS. No desktop slowdown, no UI issues - just plays the video like I was opening it on a modern multi-core machine. The microSD card that was still in there when I pulled it out still DOES function that way, although it's obviously now an unupdatable security nightmare...

But it seems that every new Raspbian OS update after that... bullseye, trixie... all play video like they're broken lemons. Playing through VLC is still PASSABLE with massive frame drops and awful UI lag, but playing video in a browser just displays solid pink colors, despite hardware acceleration being enabled.

What changed? Is it just the Wayland switch? Is it just impossible to use these things to their full potential anymore? I hate to throw out perfectly good old hardware that clearly CAN perform my use case, because the OS broke compatibility with it.

Can anybody explain what happened, or if it's fixable?

So most of my raspberry pi 4’s are deployed. But I still have a 3B, Zero 2W, Zero, 400 and a 1A that I have that I’m not doing anything with. I don’t know what would be a good project to use them with. Looking for some inspiration/ideas.

Edit: my current 4’s are hosting my pi hole, homebridge and Immich frame.

I am new to raspberry pi and have picked up a pi4 which i intend to use for small projects to learn how to use them.

I have a pi1b from years ago but only spun it up for the first time a few weeks ago to serve as a pihole and a jump box to get inside my network with tailscale for various reason.

Its not powerful enough for anything beyond that that i need

I want to start with a NAS for a media server and have read about HATs you can use but im getting confused about what is better between SATA HATs and m.2 hats or just using USB with power injection for HDDs.

I intended to set up RAID 5 with 4 SSDs but am appy to go a different route. I just want something basic but not too slow and not too bulky.

The pi is a pi4b 8gb model.

I did search before asking here and have watched a number of youtube videos but couldn't find what i needed. And overall found the videos to be confusing as they all recommend different stuff and dont really get into detail about why one is better than the other.

Thanks in advance.

Like issues with uptime, risk of backdoors, privacy concerns, etc.?

Using Raspberrian Bookworm, input connection is through an ethernet cable and the hostpot was set up through Pi-Apps' hotspot tool and is using WSA2 and password, but nothing else to note.

Not much info I could find through articles online.

I don't know much about electronics, so any advice would help.

I'm also interested in knowing realistically what the upper limits are for this sort of thing.
