I mentioned in my Pi 500 review Raspberry Pi is dogfooding their own microcontroller in the new Pi 500. An RP2040 sits next to the keyboard ribbon cable connector, and interfaces it through a USB port directly into the RP1 chip:
In good news for keyboarding enthusiasts, the RP2040 seems to be flashed with the open-source QMK ('Quantum Mechanical Keyboard') Firmware. Thanks to a reader, 'M', who figured that out!
In a win for modular, private, local IoT, I just upgraded my Home Assistant Yellow from a Raspberry Pi Compute Module 4 to a Compute Module 5 this morning, and got an instant 2x speed boost.
I first posted about the Yellow in 2022, and walked through my smart-but-private HA Yellow setup in my Studio in a video last year.
Because I was running an eMMC CM4 in the Yellow before, I ran a full backup (and downloaded it), yanked the CM4, flashed HAOS to a new NVMe SSD, and plugged that and the CM5 into my Yellow. After running a Restore (it's a handy option right on the first page that appears when you access homeassistant.local), I was up and running like there was no difference at all—just everything was a little more snappy.
After a long journey getting AMD graphics cards working on the Raspberry Pi 5, we finally have a stable patch for the amdgpu Linux kernel driver, and it works on AMD RX 400, 500, 6000, and (current-generation) 7000-series GPUs.
With that, we also have stable Vulkan graphics and compute API support.
When I wrote about getting a Radeon Pro W7700 running on the Pi, I also mentioned AMD is not planning on supporting Arm with their ROCm GPU acceleration framework. At least not anytime soon.
Luckily, the Vulkan SDK can be used in its place, and in some cases even outperforms ROCm—especially on consumer cards where ROCm isn't even supported on x86!
Recently Joshua Riek posted he's dropping off from GitHub. If you haven't heard of him, he's one of the few reasons working with Linux on Rockchip SBCs is so much easier today than it was just a few years ago.
His Ubuntu Rockchip distribution is built for Ubuntu 22 and 24, and they've been maybe the most popular and stable way to run Ubuntu on Rockchip devices.
So popular, in fact, that manufacturers who use Rockchip, like Turing Pi, build their own official images on top of Joshua's.
Now, if you're reminded of XKCD #2347, yeah, I am too.
After I saw Pineboards 4K Pi 5 external GPU gaming demo at Maker Faire Hanover, I decided it was time to set up my GPU test rig and see how the Pi OS amdgpu Linux kernel patch is going.
I tested it out on a livestream over the weekend, but I thought I'd document the current state of the patch, how to apply it, and what else is left to do to get full external GPU support on the Raspberry Pi.
I also have a full video up with more demonstrations of the GPU in use, you can watch it below:
This is the Sipeed NanoKVM. You stick it on your computer, plug in HDMI, USB, and the power button, and you get full remote control over the network—even if your computer locks up.
How did Sipeed make it so small, and so cheap? The 'full' kit above is about $50, while the cheapest competitors running PiKVM are closer to $200 and up!

A few days ago, the post Upcoming Changes to the AWX Project came across my feed. An innocuous title, but sometimes community-impacting changes are buried in posts like this. So, as an interested Ansible user, I read through the post.
In 1,610 words, almost nothing of substance was written.
A lot about how it's not 2014 anymore, so 2014-era architecture doesn't suit AWX. Then a big bold disclaimer at the bottom:
Before we conclude, we should be clear about what will not happen.
- We are not changing the Ansible project
- We are not adjusting our OSS license structure
Ultimately, we need to make some changes to the way our systems work and our projects are structured. Not a rewrite but a refactoring and restructuring of how some of the core components connect and communicate with each other.
IBM is buying HashiCorp for $6.4 billion.
That's four months after HashiCorp rugpulled their entire development community and ditched open source for the 'Business Source License.'
As someone on Hacker News pointed out so eloquently:
IBM is like a juicer that takes all the delicious flavor out of a fruit
skywhopper replied:
HashiCorp has done a good job of pre-draining any flavor it once had.
Some people wonder if HashiCorp's decision to drop open source was because they wanted to juice the books for a higher price. I mean, six billion dollars? And they're not even a pointless AI company!
Frigate's 0.13.0 release included a feature near and dear to my heart: easy exporting of timelapses, straight from the Frigate UI.
I'm a little bit nutty about timelapses, and have made them with dashcams, GoPros, full DSLRs, webcams, and even Raspberry Pi.
But one thing I haven't done (until now) is make easy timelapses from IP cameras like the Annke 4K PoE cameras I use for security around my house.
Eventually I'm planning on automating things further, but for now, here's my process for building up a timelapse that's relatively small in file size, preserving only frames where there's motion from frame to frame.
For something like clouds/sky, or natural environments, it's better to do a straight timelapse export and maybe recompress it if you want, but for indoor or outdoor security footage, it's nice to condense it down.
Raspberry Pi is looking into an IPO (Initial Public Offering).
But wait, Raspberry Pi's a non-profit! They can't do that? And who would want stock in Raspberry Pi anyway? Their core market hates them—they abandoned hobbyists and makers years ago!
And there are like tons of clones and competitors, nobody even needs Raspberry Pi? Plus, aren't they crazy-expensive? It's like a hundred bucks now, and that's if you can even find one to buy!
Well, hold on a second... there are a lotta misconceptions out there. In this post, I'll walk through what's actually happening, and also through things I see online.
