Intel GPUs On Raspberry Pi Is So Wrong It Feels Right

November 14, 2025 by 15 Comments

While you might not know it from their market share, Intel makes some fine GPUs. Putting one in a PC with an AMD processor already feels a bit naughty, but AMD’s x86 processors still ultimately trace their lineage all the way back to Intel’s original 4004. Putting that same Intel GPU into a system with an ARM processor, like a Raspberry Pi, or even better, a RISC V SBC? Why, that seems downright deviant, and absolutely hack-y. [Jeff Geerling] shares our love of the bizarre, and has been working tirelessly to get a solid how-to guide written so we can all flout the laws of god and man together.

According to [Jeff], all of Intel’s GPUs should work, though not yet flawlessly. In terms of 3D acceleration, OpenGL works well, but Vulkan renders are going to get texture artifacts if they get textures at all. The desktop has artifacts, and so do images; see for yourself in the video embedded below. Large language models are restricted to the not-so-large, due to memory addressing issues. ARM and RISC V both handle memory somewhat differently than x86 systems, and apparently the difference matters. Continue reading “Intel GPUs On Raspberry Pi Is So Wrong It Feels Right” →

Have A Slice Of Bumble Berry Pi

November 11, 2025 by 10 Comments

[Samcervantes] wanted a cyberdeck. Specifically, he wanted a Clockwork Pi uConsole, but didn’t want to wait three months for it. There are plenty of DIY options, but many of them are difficult to build. So [Sam] did the logical thing: he designed his own. The Bumble Berry Pi is the result.

The design criteria? A tactile keyboard was a big item. Small enough to fit in a pants pocket, but big enough to be useful. What’s more is he wanted to recycle some old Pi 3Bs instead of buying new hardware.

Countdown To Pi 1 Loss Of Support, Activated

November 6, 2025 by 62 Comments

The older Raspberry Pi boards have had a long life, serving faithfully since 2012. Frankly, their continued support is a rarity these days — it’s truly incredible that an up-to-date OS image can still be downloaded for them in 2025. All good things must eventually come to an end though, and perhaps one of the first signs of that moment for the BCM2385 could be evident in Phoronix’s report on Debian dropping support for MIPS64EL & ARMEL architectures. Both are now long in the tooth and other than ARMEL in the Pi, rarely encountered now, so were it not for the little board from Cambridge this might hardly be news. But what does it mean for the older Pi?

It’s first important to remind readers that there’s no need to panic just yet, as the support is going not for the mainstream Debian releases, but the unstable and experimental ones. The mainstream Debian support period for the current releases presumably including the Debian-based Raspberry Pi OS extends until 2030, which tallies well with Raspberry Pi’s own end-of-life date for their earlier boards. But it’s a salutary reminder that that the clock’s ticking, should (like some of us) you be running an older Pi.  You’ve got about five years.

Spectravideo Computers Get A Big Upgrade

November 5, 2025 by 2 Comments

Spectravideo is not exactly the most well-known microcomputer company, but they were nevertheless somewhat active in the US market from 1981 to 1988. Their computers still have a fanbase of users and modders. Now, as demonstrated by [electricadventures], you can actually upgrade your ancient Spectravideo machine with some modern hardware.

The upgrade in question is the SVI-3×8 PicoExpander from [fitch]. It’s based on a Raspberry Pi Pico 2W, and is built to work with the Spectravideo 318 and 328 machines. If you’re running a 328, it will offer a full 96kB of additional RAM, while if you’re running a 318, it will add 144 kB more RAM and effectively push the device up to 328 spec. It’s also capable of emulating a pair of disk drives or a cassette drive, with saving and loading images possible over Wi-Fi.

It’s worth noting, though, that the PicoExpander pushes the Pico 2W well beyond design limits, overclocking it to 300 MHz (versus the original 150 MHz clock speed). The makers note it is “bleeding edge” hardware and that it may not last as long as the Spectravideo machines themselves.

Design files are available on Github if you want to spin up your own PicoExpander, or you can just order an assembled version. We’ve seen a lot of other neat retrocomputer upgrades built around modern hardware, too. Video after the break.

Pi Zero Powers A Little Indoor Rover

November 2, 2025 by 3 Comments

Not every robot has to be big. Sometimes, you can build something fun that’s better sized for exploring your tabletop rather than the wastelands of Mars. To that end, [philosiraptor] built the diminutive PITANK rover.

As you might guess from the name, the rover is based on the Raspberry Pi Zero 2. It uses the GPIO pins to output PWM signals, commanding a pair of servos that drive the tracks on either side of the ‘bot. The drivetrain and chassis are made from 3D-printed components. Controlling the robot is handled via a web interface, which [philosiraptor] coded in C# to be as responsive as possible. So you can see where you’re driving, the ‘bot is also kitted out with a camera to provide a live video feed.

Given its low ground clearance and diminutive size, you’re not going to go on big outdoor adventures with PITANK. However, if you wish to explore a nice flat indoor environment, its simple tracked drivetrain should do nicely. We’ve featured a great many rovers over the years; if you’ve got a particularly special one, don’t hesitate to notify the tipsline!

Original E39 Head Unit Modernized

October 28, 2025 by 24 Comments

Although most modern cars have moved to using proprietary components nearly everywhere, especially when it comes to infotainment systems, for a brief moment which peaked in the 90s and 00s most cars shipped with radios that fit in a standard size opening called a DIN slot. If you wanted a new Pioneer or Kenwood stereo it was usually a simple matter to slide the factory radio out and put your choice of aftermarket head unit in its place. [Stefan] has an E39 BMW from this era and wanted to upgrade the factory radio but use the original hardware instead of replacing it.

This isn’t just a simple stereo upgrade either. [Stefan] has gone all-out for this build which he started in 2020. Beginning with a Kotlin/Jetpack Compose Linux application to handle control input from the vehicle’s various knobs and buttons he moved on to a map application and an on-screen keyboard. From there he implemented VGA to send video to the OEM screen, and now has a fully functional system based on a Raspberry Pi. It does everything the original unit can do including playing music and showing the feed from the backup camera, plus adds plenty of new, modern features like Bluetooth.

For a certain classic car enthusiast, this build hits a sweet spot of modernizing a true classic like the E39 without removing or permanently modifying any OEM components. The amount of work that went into it is pretty staggering as well, with [Stephan] putting in over 100 hours of work just to get the video signal timing correct. We also like it because it reminds us of the flash-in-the-pan “carputer” trend from the late 00s where people in the pre-smartphone age were shoving all kinds of computing horsepower in their trunks.

Handheld PC Build Is Pleasantly Chunky

October 22, 2025 by 20 Comments

The cool thing about building your own computer is that you don’t have to adhere to industry norms of form and function. You can build whatever chunky, awesome thing your heart desires, and that’s precisely what [Rahmanshaber] did with the MutantC cyberdeck.

The build is based around a Raspberry Pi Compute Module 4. If you’re unfamiliar with the Compute Module, it’s basically a Raspberry Pi that has been designed specifically for easy integration into a larger carrier PCB. In this case, the carrier PCB interfaces all the other necessary gear to make this a fully functional computer. The PCB is installed inside a vaguely-rectangular 3D-printed enclosure, with a 5-inch TFT LCD on a sliding mount. Push the screen up, and it reveals a small-format keyboard for text entry. There’s also a hall-effect joystick and a couple of buttons for mouse control to boot. [Rahmanshaber] has designed the computer to run off a couple of different battery packs—you can use a pair of 18650 cells if you like, or switch to lager 21700 cells if you want greater capacity for longer running time.

If you want a portable Raspberry Pi cyberdeck, you might find this to be a great inspiration. We’ve featured many other designs in this vein before, too. Video after the break.
