Jellybean Mac Hides Modern PC

May 7, 2025 by 20 Comments

The iMac G3 is an absolute icon of industrial design, as (or perhaps more) era-defining than the Mac Classic before it. In the modern day, if your old iMac even boots, well, you can’t do much with it. [Rick Norcross] got a hold of a dead (hopefully irreparable) specimen, and stuffed a modern PC inside of it.

From the outside, it’s suprizingly hard to tell. Of course the CRT had to go, replaced with a 15″ ELO panel that fits well after being de-bezeled. (If its resolution is only 1024 x 768, well, it’s also only 15″, and that pixel density matches the case.) An M-ATX motherboard squeezes right in, above a modular PSU. Cooling comes from a 140 mm case fan placed under the original handle. Of course you can’t have an old Mac without a startup chime, and [Rick] obliges by including an Adafruit FX board wired to the internal speakers, set to chime on power-up while the PC components are booting.

These sorts of mods have proven controversial in the past– certainly there’s good reason to want to preserve aging hardware–but perhaps with this generation of iMac it won’t raise the same ire as when someone guts a Mac Classic. We’ve seen the same treatment given to a G4 iMac, but somehow the lamp doesn’t quite have the same place in our hearts as the redoubtable jellybean.

An IPhone Case Study

December 15, 2024 by 14 Comments

Way back in 2008, Apple unveiled the first unibody Macbook with a chassis milled out of a single block of aluminum. Before that, essentially all laptops, including those from Apple, were flimsy plastic screwed together haphazardly on various frames. The unibody construction, on the other hand, finally showed that it was possible to make laptops that were both lightweight and sturdy. Apple eventually began producing iPhones with this same design style, and with the right tools and a very accurate set of calipers it’s possible to not only piece together the required hardware to build an iPhone from the ground up but also build a custom chassis for it entirely out of metal as well.

The first part of the project that [Scotty] from [Strange Parts] needed to tackle was actually getting measurements of the internals. Calipers were not getting the entire job done so he used a flatbed scanner to take an image of the case, then milled off a layer and repeated the scan. From there he could start testing out his design. After an uncountable number of prototypes, going back to the CAD model and then back to the mill, he eventually settles into a design but not before breaking an iPhone’s worth of bits along the way. Particularly difficult are the recessed areas inside the phone, but eventually he’s able to get those hollowed out, all the screw holes tapped, and then all the parts needed to get a working iPhone set up inside this case.

[Scotty] has garnered some fame not just for his incredible skills at the precision mill, but by demonstrating in incredible detail how smartphones can be user-serviceable or even built from scratch. They certainly require more finesse than assembling an ATX desktop and can require some more specialized tools, but in the end they’re computers like any other. For the most part.

Retro Hackintosh Made From Retro Parts

March 25, 2024 by 20 Comments

Apple as a company, has staked most of its future around being a “walled garden” where it controls everything from the hardware up through the user experience. In some ways this is good for users; the hardware is generally high quality and vetted by the company creating the software, making for a very uniform experience. This won’t stop some people from trying to get Apple’s operating systems and other software running on unapproved hardware though. These “Hackintosh” computers were much more common in the Intel era but this replica goes even further back to the Macintosh era.

Originally [Kevin] had ordered an authentic Macintosh with the intent of getting it working again, but a broken floppy disk drive and lack of replacement parts turned this project into a different beast. He used the Mac instead as a model for a new 3D-printed case, spending a ton of time sanding, filling, and finishing it to get it to look nearly indistinguishable from the original. The hardware going in this replica is an old Linux-based thin client machine running the Mini vMac operating system, with a modified floppy drive the computer uses to boot. A hidden SD card slot helps interface with modern computers. The display is a modern LCD, though a sheet of acrylic glued to the front panel replicates a bit of the CRT curve.

Thin Keyboard Fits In Steam Deck Case

September 6, 2023 by 13 Comments

Although some of the first Android-powered smartphones had them and Blackberries were famous for them, physical keyboards on portable electronics like that quickly became a thing of the past. Presumably the cost to manufacture is too high and the margins too low regardless of consumer demand. Whatever the reason, if you want a small keyboard for your portable devices you’ll likely need to make one yourself like [Kārlis] did for the Steam Deck.

Unlike a more familiar mechanical keyboard build which prioritizes the feel and sound of the keyboard experience, this one sacrifices nearly every other design consideration in order to be thin enough to fit in the Steam Deck case. The PCB is designed to be flexible using copper tape cut to size with a vinyl cutter with all the traces running to a Raspberry Pi Pico which hosts the firmware and plugs into the Steam Deck’s USB port. The files for the PCB are available in KiCad and can be exported as SVG files for cutting.

In the end, [Kārlis] has a functioning keyboard that’s even a little more robust than was initially expected and which does fit alongside the Deck in its case. On the other hand, [Kārlis] describes the typing experience as “awful” due to its extreme thinness, but either way we applaud the amount of effort that went in to building a keyboard with this form factor. The Steam Deck itself is a platform which lends itself to all kinds of modifications as well, from the control sticks to the operating systems, and Valve will even show you how.

Retro-Inspired Computer Case Hosts Mechanical Keyboard

June 24, 2023 by 5 Comments

During the time in the 1980s when the personal computer was gaining steam as a household fixture, plenty of models shipped with the keyboard built in to the machine itself. This helped reduce costs, lower the physical footprint of the device, and arguably improved aesthetics. But as technology progressed, this type of design fell by the wayside as computers became more modular and configurable. That’s not to say there aren’t any benefits to building a computer like this, though. [jit] is here to show off this Amiga-inspired computer with its own modern built-in mechanical keyboard.

Like the Raspberry Pi 400 which is built into its own case, modern computers like this are extremely portable, relatively simple, and space-efficient. But [jit] did not like the uninspired design of the Pi so he was looking to make some improvements. Starting with the keyboard, it boasts a 60% size board with mechanical keys which are backlit by LEDs. Inside the machine is a Odroid XU4 which has a little bit more power (and is often easier to find) than a comparable Raspberry Pi. The case is 3D printed and includes ventilation and support for the addition of various cooling fans, I/O ports, status LEDs, and switches for the computer inside.

Additionally, some modification of the Odroid itself was needed in order to move the various switches to the case, and the build also includes a somewhat customized power supply internally as well. It’s a well-rounded build that captures the spirit of the old computer cases, but takes advantage of a lot of modern technology at the same time. If you want to go all-out with a build like this, though, take a look at this retro-inspired case (with keyboard included) that manages to get most of a Framework laptop inside.

Classic Gaming With FPGA And ATX

March 14, 2023 by 5 Comments

Playing classic games, whether they are games from the golden age of arcades or simply games from consoles that are long out of production, tends to exist on a spectrum. At one end is grabbing a game’s ROM file, finding an emulator, and kludging together some controls on a keyboard and mouse with your average PC. At the other is meticulously restoring classic hardware for the “true” feel of what the game would have felt like when it was new. Towards the latter end is emulating the hardware with an FPGA which the open-source MiSTer project attempts to do. This build, though, adds ATX capabilities for the retrocomputing platform.

Ultimate Game And Watch Has Support For NES

December 9, 2022 by 2 Comments

We’ve talked about feature creep plenty of times around here, and it’s generally regarded as something to be avoided when designing a prototype. It might sound good to have a lot of features in a build, but this often results in more complexity and more difficulty when actually bringing a project to fruition. [Brendan] has had the opposite experience with this custom handheld originally designed for Game and Watch games, though, and he eventually added NES and Game Boy functionality as well.

As this build was originally intended just for Game and Watch games, the screen is about the size of these old games, and while it can easily mimic the monochrome LCD-style video that would have been present on these 80s handhelds, it also has support for color which means that it’s the perfect candidate for emulating other consoles as well. It’s based around a Raspberry Pi Zero 2W and the enclosure is custom printed and painted. Some workarounds for audio had to be figured out, though, since native analog output isn’t supported, but it still has almost every feature for all of these systems.

While we’ve seen plenty of custom portable builds from everything from retro consoles to more modern ones, the Game and Watch catalog is often overlooked. There are a few out there, but in this case we appreciate the feature creep that allowed this build to support Game Boy and NES games as well.
