Use an External GPU on Raspberry Pi 5 for 4K Gaming 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.

Snapdragon Dev Kit for Windows - the fastest X Elite, tested I have mixed feelings publishing this post: many developers who are actively trying to port their Windows software to Arm are still awaiting shipment of their own Snapdragon Dev Kits, and I seem to be one of the first few people to receive one. Everyone I've been in contact with also ordered the Dev Kit on July 16, but we've all been waiting for it to ship—for months. Jeff Geerling October 2, 2024 ..read more

AVerMedia Live Gamer Portable 2 Plus - Can't record to microSD I recently purchased an AVerMedia Live Gamer Portable 2 Plus to help record screens on devices I test at my desk. It's claim to fame is being able to record to a microSD card standalone (at resolutions up to 1080p60), without having a separate computer attached. For my 4K cameras, I typically use an Atomos Ninja V, since it can record in full 4K resolution, but that thing is $700—the Live Gamer Portable is $120, and runs a lot cooler (and quieter). I don't enjoy dealing with microSD cards, but it's more convenient than having to u ..read more

Qualcomm Snapdragon Dev Kit for Windows Teardown (2024) In late July, a week after ordering the Snapdragon Dev Kit, I wondered where it was. Arrow's website said 'Ships tomorrow' when I ordered, after all. Many developers eager to test their code on Windows on Arm, on the premiere new 'CoPilot+' PCs that would revolutionize computing as we know it, were also wondering.

Elecrow responded, apologized for AI voice cloning AI voice cloning is a tool. It can be used, and it can be abused. Your browser does not support the video tag. Last week I was made aware that Elecrow, an electronics manufacturer and distributor, was using an unauthorized clone of my voice in some of their YouTube tutorials. I couldn't prove it at the time, but there are AI identity detection services like Resemble.ai that can at least give some input into whether it was a direct clone or just something that sounds 'midwestern US male.' Anyway, I made a short video about it, because I wanted ..read more

They stole my voice with AI Listen to this clip: Your browser does not support the video tag. I don't know about you, but that sounds pretty familiar. I mean I would like you to subscribe to my YouTube channel. But that's the Jeff Geerling channel, not Elecrow, where the clip above is from. I never said the words that are in that video. Someone emailed me a link to Elecrow's video and said it sounded off. I'm guessing at least some of the thousands of people who watched the video thought I agreed to voice some Elecrow videos, since I talk about some of the same topics on my channel.

Sipeed NanoKVM: A RISC-V stick-on 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! This blog post is a lightly-edited transcript of the following video on my YouTube channel: Jeff Geerling September 20, 2024 ..read more

What happens when you touch a Pickle to an AM radio tower? A few months ago, our AM radio hot dog experiment went mildly viral. That was a result of me asking my Dad 'what would happen if you ground a hot dog to one of your AM radio towers?' He didn't know, so one night on the way to my son's volleyball practice, we tested it. And it was awesome. There's a video and some pictures in my hot dog radio blog post from back in March.

New 2GB Pi 5 has 33% smaller die, 30% idle power savings Raspberry Pi launched the 2 gig Pi 5 for $50, and besides half the RAM and a lower price, it has a new stepping of the main BCM2712 chip. This is the BCM2712 D0 stepping. Older Pi 5's shipped with a C1. In their blog post, they said: The new D0 stepping strips away all that unneeded functionality, leaving only the bits we need. Steppings are basically chip revisions where they don't change functionality, and usually just fix bugs, or tweak the layout. But even tiny design changes could have unintended consequences. I wanted to see ex ..read more

Positron - an upside-down and portable 3D printer I've been getting into 3D printing lately. I have an older Ender 3 V2 at home I bought during COVID. And in the past year I've acquired an Ender 3 S1, Bambu Labs P1S, and Prusa MK4. I also dove head-first into 3D CAD, and designed a number of small SBC cases or parts to help with things around the house. But I'd never built my own 3D printer from a kit—all the printers I've had were pre-built and at most, required assembling the prebuilt gantry or toolhead. That finally changed with the Positron V3.2: Jeff Geerling August 26, 2024 ..read more
