I Installed Gentoo So You Don’t Havtoo

November 4, 2024 by 73 Comments

A popular expression in the Linux forums nowadays is noting that someone “uses Arch btw”, signifying that they have the technical chops to install and use Arch Linux, a distribution designed to be cutting edge but that also has a reputation of being for advanced users only. Whether this meme was originally posted seriously or was started as a joke at the expense of some of the more socially unaware Linux users is up for debate. Either way, while it is true that Arch can be harder to install and configure than something like Debian or Fedora, thanks to excellent documentation and modern (but optional) install tools it’s no longer that much harder to run than either of these popular distributions.

For my money, the true mark of a Linux power user is the ability to install and configure Gentoo Linux and use it as a daily driver or as a way to breathe life into aging hardware. Gentoo requires much more configuration than any mainline distribution outside of things like Linux From Scratch, and has been my own technical white whale for nearly two decades now. I was finally able to harpoon this beast recently and hope that my story inspires some to try Gentoo while, at the same time, saving others the hassle.

A Long Process, in More Ways Than One

My first experience with Gentoo was in college at Clemson University in the late ’00s. The computing department there offered an official dual-boot image for any university-supported laptop at the time thanks to major effort from the Clemson Linux User Group, although the image contained the much-more-user-friendly Ubuntu alongside Windows. CLUG was largely responsible for helping me realize that I had options outside of Windows, and eventually I moved completely away from it and began using my own Linux-only installation. Being involved in a Linux community for the first time had me excited to learn about Linux beyond the confines of Ubuntu, though, and I quickly became the type of person featured in this relevant XKCD. So I fired up an old Pentium 4 Dell desktop that I had and attempted my first Gentoo installation.

For the uninitiated, the main thing that separates Gentoo from most other distributions is that it is source-based, meaning that users generally must compile the source code for all the software they want to use on their own machines rather than installing pre-compiled binaries from a repository. So, for a Gentoo installation, everything from the bootloader to the kernel to the desktop to the browser needs to be compiled when it is installed. This can take an extraordinary amount of time especially for underpowered machines, although its ability to customize compile options means that the ability to optimize software for specific computers will allow users to claim that time back when the software is actually used. At least, that’s the theory. Continue reading “I Installed Gentoo So You Don’t Havtoo” →

90s PowerBook Runs MacOS Monterey

May 22, 2024 by 12 Comments

Even though Apple isn’t known for making the most pro-consumer devices ever (at least not since the Apple II), the trope that Apples aren’t upgradable, customizable, or otherwise hackable doesn’t really hold much weight. It does take more work to modify them or change how Apple wants them to behave, but it’s not completely impossible. Take this example of a ’94 Apple PowerBook which runs macOS Moneterey thanks largely to new internals from a 2015 MacBook Pro.

[Billy] originally intended for a Raspberry Pi to go inside this old PowerBook, but at the time, prices for ARM single-board computer (SBC) were astronomical. For around the same price as the Pi was at the time, he was able to pick up a retina display from an iPad and the internals from a broken MacBook Pro to outfit this retro case. There’s also a Teensy installed to get the trackpad working and a driver board for the display from Adafruit, and a number of case mods were needed to get everything to fit including the screen which was slightly larger than the original 9.5″ display the laptop would have shipped with.

This project took both inspiration and some of the actual code needed to get everything working from another project we featured a while ago where a Mac Mini was installed inside of a PowerBook case from 1993. Unlike projects that use smaller SBCs for retrocomputing, these builds are notable because the hardware on the inside makes them usable as daily driver computers even today, and might even be an upgrade if you’re using the internals from a MacBook Pro that would have originally had a butterfly keyboard.

Best Of Both Worlds: The MacPad

March 6, 2024 by 9 Comments

Despite a growing demand for laptop-tablet hybrid computers from producers like Lenovo, HP, and Microsoft, Apple has been stubbornly withdrawn this arena despite having arguably the best hardware and user experiences within the separate domains of laptop and tablet. Charitably one could speculate that this is because Apple’s design philosophy mandates keeping the user experiences of each separate, although a more cynical take might be that they can sell more products if they don’t put all the features their users want into a single device. Either way, for now it seems that if you want a touchscreen MacBook you’ll have to build one yourself like the MacPad from [Federico].

This project started as simply providing a high-quality keyboard and mouse for an Apple Vision Pro, whose internal augmented reality keyboard is really only up to the task of occasionally inputting a password or short string. For more regular computing, [Federico] grabbed a headless MacBook which had its screen removed. This worked well enough that it triggered another line of thought that if it worked for the Vision Pro it might just work for an iPad Pro as well. Using Apple tools like Sidecar makes this almost trivially easy from a software perspective, although setting up the iPad as the only screen, rather than an auxiliary screen, on the MacBook did take a little more customization than normal.

The build goes beyond the software side of setting this up, though. It also includes a custom magnetic mount so that the iPad can be removed at will from the MacBook, freeing both the iPad for times when a tablet is the better tool and the MacBook for when it needs to pull keyboard duty for the Vision Pro. Perhaps the only downsides are that this only works seamlessly when both devices are connected to the same wireless network and that setting up a headless MacBook without a built-in screen takes a bit of extra effort. But with everything online and working it’s nearly the perfect Apple 2-in-1 that users keep asking for. If you’re concerned about the cost of paying for an iPad Pro and a Macbook just to get a touchscreen, though, take a look at this device which adds a touchscreen for only about a dollar.

Hack Lets Intel MacBook Run Without A Battery

February 17, 2023 by 31 Comments

A long time ago, a laptop was a basic thing, and you could pretty much run one just by hooking up a power supply to the battery contacts. A modern MacBook is altogether fussier. However, when [Christophe] was stuck in the midst of a 2020 lockdown with no parts available, he found a way to get his damaged MacBook up and running without a battery.

The problem was brought about by a failing battery in the MacBook Pro 13″ from mid-2018, which swelled up and deformed the laptop’s case. Parts were unavailable, and the MacBook wouldn’t run at full speed without a battery fitted. That’s because with no battery present, the MacBook would send a BD_PROCHOT signal to the Intel CPU, telling it to slow down due to overheating, even when the chip was cool.

To get around the problem, [Christophe] used a tool called CPUTune. It allows fiddling with the various CPU settings of a MacBook. He deactivated the BD_PROCHOT signal, and also the CPU’s Turbo Boost feature. This ended the worst of the thermal throttling, and enabled semi-normal use of the machine.

It’s unclear why Apple would throttle the CPU with the battery disconnected. [Christophe]’s workaround got him back up and working again in the midst of a difficult period, regardless. We’ve seen some other great Macbook hacks before too, like this amazing save from serious water damage!

Are Slabtops The Future Of Computing?

November 25, 2022 by 114 Comments

The most popular computer ever was the Commodore 64 with its computer-in-a-keyboard form factor. If you have a longing for a keyboard computer with more modern internals, one of the easiest solutions today is to pull the screen off a laptop.

[Umar Shakir] wanted to see what the fuss was about regarding a recent Apple patent and took the top lid off of his M1 Macbook Air and turned it into a “slabtop.” The computer works great wired to a monitor but can also be used wirelessly via AirPlay. The approach doesn’t come without its downsides, of course. Newer MacBooks can’t access recovery mode without the built-in screen, and some older models had their WiFi antennas in the top lid, so making one into a slabtop will leave you desk-bound.

While [Shakir] focuses on MacBooks, this approach should work with any laptop. Apparently, it’s a cottage industry in China already. Back in the day, my own daily driver was a Pentium-powered laptop with its broken LCD (and lid) removed. It worked great with whatever CRT was nearby.

If you’re looking for an off-the-shelf keyboard computer of your own, you might want to check out the Raspberry Pi 400.

Macbook Gets NVMe SSD With Help Of A BGA-Imitating PCB

May 31, 2022 by 12 Comments

Recently, we stumbled upon a video by [iBoff], adding an M.2 NVMe port to a 2011-2013 MacBook. Apple laptops never came with proper M.2 ports, especially the A1278 – so what’s up? The trick is – desoldering a PCIe-connected Thunderbolt controller, then soldering a BGA-like interposer PCB in place of where the chip was, and pulling a cable assembly from there to the drive bay, where a custom adapter PCB awaits. That adapter even lets you expose the PCIe link as a full-sized PCIe 4x slot, in case you want to connect an external GPU instead of the NVMe SSD!

The process is well-documented in the video, serving as an instruction manual for anyone attempting to install this specific mod, but also a collection of insights and ideas for anyone interested in imitating it. The interposer board ships with solder balls reballed onto it, so that it can be installed in the same way that a BGA chip would be – but the cable assembly connector isn’t installed onto the interposer, since it has to be soldered onto the mainboard with hot air, which would then melt the connector. The PCB that replaces the optical drive makes no compromises, either, tapping into the SATA connector pins and letting you add an extra 2.5mm SATA SSD.

Adding an NVMe drive is an underappreciated way to speed up your old laptop, and since they’re all PCIe under the hood, you can really get creative with the specific way you add it. You aren’t even limited to substituting obscure parts like Thunderbolt controllers – given a laptop with a discrete GPU and a CPU-integrated one, you could get rid of the discrete GPU and replace it with an adapter for one, or maybe even two NVMe drives, and all you need is a PCB that has the same footprint as your GPU. Sadly, the PCB files for this adapter don’t seem to be open-source, but developing a replacement for your own needs would be best started from scratch, either way.

We’ve seen such an adapter made for a Raspberry Pi 4 before, solderable in place of a QFN USB 3.0 controller chip and exposing the PCIe signals onto the USB 3 connector pins. However, this one takes it up a notch! Typically, without such an adapter, we have to carefully solder a properly shielded cable if we want to get a PCIe link from a board that never intended to expose one. What’s up with PCIe and why is it cool? We’ve talked about that in depth!

3D Printed Mini MacBook With A Raspberry Pi Heart

October 8, 2020 by 14 Comments

Do you like the sleek look of Apple’s laptops? Are you a fan of the Raspberry Pi? Have a particular affinity for hot glue and 3D printed plastic? Then you’re in luck, because this tiny “MacBook” built by serial miniaturizer [Michael Pick] features all of the above (and a good bit more) in one palm-sized package. (Video link, embedded below.)

Getting the LCD panel and Raspberry Pi 4 to fit into the slim 3D printed case took considerable coaxing. In the video after the break, you can see [Michael] strip off any unnecessary components that would stand in his way. The LCD panel had to lose its speakers and buttons, and the Pi has had its Ethernet and USB ports removed. While space was limited, he did manage to squeeze an illuminated resin-printed Apple logo into the lid of the laptop to help sell the overall look.

The bottom half of the machine has a number of really nice details, like the fan grill cut from metal hardware cloth and a functional “MagSafe” connector made from a magnetic USB cable. The keyboard PCB and membrane was liberated from a commercially available unit, all [Michael] needed to do was model in the openings for the keys. Since the keyboard already came with its own little trackpad, the lower one is just there for looks.

Speaking of which, to really drive home the Apple aesthetic, [Michael] made the bold move of covering up all the screws with body filler after assembly. It’s not a technique we’d necessarily recommend, but gluing it shut would probably have made it even harder to get back into down the line.

We’ve previously seen [Michael] create a miniature rendition of the iMac and an RGB LED equipped “gaming” computer using many of the same parts and techniques. He’ll have to start branching off into less common machines to replicate soon, which reminds us that we’re about due for another tiny Cray X-MP.
