Edit: The solution in my case was to run these commands:

sudo apt update
sudo apt install linux-image-rpi-v8 linux-headers-rpi-v8

The new kernel wasn't used after rebooting though, so I had to edit /boot/config.txt and add:

# New kernel (test)
kernel=vmlinuz-6.12.75+rpt-rpi-v8
initramfs initrd.img-6.12.75+rpt-rpi-v8 followkernel

I'll figure out how to make it so I don't have to manually keep config.txt updated but for now, I'm happy to have a process to stay up to date with current kernels.

Reading about the latest Copy Fail security vulnerability I realised I was overdue a check on my system. It turns out I had even bigger problems - I was still on Debian 10/Buster.

To solve it I updated my apt list to contain: deb http://archive.raspberrypi.org/debian/ bookworm main

But after doing this, updating and doing a full upgrade, my kernel is still 6.1.21.

I'm now reading that I should not have upgraded from bullseye to bookworm, so what is the easiest way forward from here? If there is a documented set of steps for this scenario I'd appreciate a link. I have a lot of services and scripts so reinstalling from scratch is not really an option.

The United States FCC recently announced a ban on new consumer-grade routers produced outside of the US. This does not affect existing devices that were already authorized, and there is a carve-out for manufacturers to apply for a conditional approval. It's difficult to say what the medium or longterm effects of the ban will be.

This got me thinking about what could be used as a makeshift router in a pinch. As it so happens, any computer that can run Linux and has networking interfaces can function as a router. This blog post by Noah Baily documents the process using various old computers and components as custom routers over the years.

These makeshift routers are not going to win any bandwidth speed races, but they're perfectly capable of routing traffic for IoT devices or basic browsing. They're also useful for capturing traffic to analyze or sharing internet access from WiFi to Ethernet or vice-versa.

This guide documents the setup process and capabilities of using a Raspberry Pi as a router. It does not require a particularly powerful computer, even the older Pi 3 B+ that lots of us have tucked away in an old parts bin works fine for this.

This board turns a Raspberry Pi CM5 into a NAS with support for 5 HDDs

Hi all, I'm trying to figure out a good easy setup for a baby monitor, I've got a pi4, pi camera 2 noir, but it's too dark to see anything by itself, and it feels like I'm leaving the plug & play zone where I could just google & program, and am entering the buy an LED and solder zone, which scares me. Any suggestions?

Although [Thomas] really likes the Raspberry Pi Pico 2 and the RP2350 MCU, he absolutely, totally, really doesn’t like the micro-USB connector on it. Hence he jumped on the opportunity to source a Pico 2 clone board with the same MCU but with a USB-C connector from AliExpress. After receiving the new board, he set about comparing the two to see whether the clone board was worth it after all. In the accompanying video you can get even more details on why you should avoid this particular clone board.

In the video the respective components of both boards are analyzed and compared to see how they stack up. The worst issues with the clone Pico 2 board are an improper USB trace impedance at 130 Ω with also a cut ground plane below it that won’t do signal integrity any favors.

There is also an issue with the buck converter routing for the RP2350 with an unconnected pin (VREG_FB) despite the recommended layout in the RP2350 datasheet. Power supply issues continue with the used LN3440 DC-DC converter which can source 800 mA instead of the 1A of the Pico 2 version and performed rather poorly during load tests, with one board dying at 800 mA load.

Two months ago, we announced increases to the prices of some Raspberry Pi 4 and 5 products. These were driven by an unprecedented rise in the cost of LPDDR4 memory, thanks to competition for memory fab capacity from the AI infrastructure roll-out.

Price rises have accelerated as we enter 2026, and the cost of some parts has more than doubled over the last quarter. As a result, we now need to make further increases to our own pricing, affecting all Raspberry Pi 4 and 5, and Compute Module 4 and 5, products that have 2GB or more of memory.

The Raspberry Pi has been a revolutionary computer in the maker space, providing a full Linux environment, GUI, and tons of GPIO and other interfacing protocols at a considerably low price. This wasn’t its original intended goal, though. Back in the early 2010s it was supposed to be an educational tool for students first, not necessarily a go-to for every electronics project imaginable. As such there are a few issues with the platform when being used this way, and [Vin] addresses his problems with its power management in his latest project.

Setting up access to a headless Raspberry Pi is one of those tasks that should take a few minutes, but for some reason always seems to take much longer. The most common method is to configure Wi-Fi access and an SSH service on the Pi before starting it, which can go wrong in many different ways. This author, for example, recently spent a few hours failing to set up a headless Pi on a network secured with Protected EAP, and was eventually driven to using SSH over Bluetooth. This could thankfully soon be a thing of the past, as [Paul Oberosler] developed a package for SSH over USB, which is included in the latest versions of Raspberry Pi OS.

The idea behind rpi-usb-gadget is that a Raspberry Pi in gadget mode can be plugged into a host machine, which recognizes it as a network adapter. The Pi itself is presented as a host on that network, and the host machine can then SSH into it. Additionally, using Internet Connection Sharing (ICS), the Pi can use the host machine’s internet access. Gadget mode can be enabled and configured from the Raspberry Pi Imager. Setting up ICS is less plug-and-play, since an extra driver needs to be installed on Windows machines. Enabling gadget mode only lets the selected USB port work as a power input and USB network port, not as a host port for other peripherals.

Raspberry Pi Imager, a tool that helps users easily write OS images to an SD card for booting a Raspberry Pi, has just released version 2.0.5, now available for download.

On macOS, the update introduces proper dark mode and Liquid Glass icon support using pre-compiled assets. The release also adds an icon compilation script, allowing developers to regenerate icon assets more easily when needed.

Several user interface adjustments land across platforms. The update popup now tracks versions more reliably, resolving issues where update notifications could behave incorrectly. BaseDialog components have been adjusted to enforce a more appropriate minimum height, improving usability on smaller displays.

Raspberry Pi Imager, a tool that helps users easily write OS images to an SD card for booting a Raspberry Pi, has just released version 2.0.4, now available for download.

A new write progress watchdog actively monitors stalled operations, while additional recovery strategies address problematic async I/O scenarios by dynamically reducing queue depth or falling back to synchronous writes when required. Timeout handling has been standardized across platforms, with a five-minute emergency timeout acting as a final safeguard against unresponsive operations.

Specifically I'm using the OrangePi Zero 2W and the Banana Pi M4 Zero (both are Pi Zero form factor), but I figure if it works in a Raspberry Pi it should work in these. Wondering if they're worth the cost, if they work at all, and/or if it's just asking for trouble.

The project I'm working on requires a good bit of storage. It's essentially an "internet in a box" device that has a portable selection of media (Wikipedia dump, music, TV shows, movies, and books) as well as web-based software to view them (Kiwix, MPD+Snapcast, Jellyfin, Calibre-Web, etc) as well as some other utilities (PiHole for DNS/DHCP/ad blocking, Searx-NG, VPN clients and routing, etc).

The OrangePi is currently the working prototype, and it has a 512 GB SD card and a 512GB USB-connected NVMe. Due to a quirky wifi chip, it requires a separate USB wifi adapter to do hotspot. Because of this, it kind of sprawls and isn't very portable without disassembly.

The Banana Pi has a better wifi chip and can do hotspot internally. So to keep my portable server keychain sized, I'd like to outfit it with either a 1 TB or 1.5 TB SD card for its media store rather than attaching a USB->NVMe enclosure. This one also has eMMC for the system, so it wouldn't be booting from or writing logs, etc to the SD card. Most of the data/media on the SD card would be WORM (write once, read many) but would be updated/refeshed periodically.

Would a large 1 or 1.5 TB SD card (Samsung or Sandisk, depending on price) be a waste of money or be a cause of issues?
