The Next Evolution Of The Raspberry Pi Recovery Kit

At Hackaday, the projects we cover are generally a one-off sort of thing. Somebody makes something, they post it online, we share it with our audience — rinse and repeat. If a project really captures people’s imaginations, it might even inspire a copy or two, which is gratifying for everyone involved. But on the rarest of occasions, we run across a project like [Jay Doscher]’s Recovery Kit.

To say that the Recovery Kit was an inspiration to others would be putting it mildly. Revolutionary would be more like it, as it resulted in more “Pi-in-a-Pelican” builds than we could possibly count. So it’s only natural that [Jay] would return to the well and produce a second version of his heavy-duty cyberdeck.

A "portable" computer in a grey enclosure. There is a small CRT on the left hand side of the face of the enclosure and a disk drive and a couple ports exposed on the right hand side. The keyboard is attached with a purple cable. A black cartridge with a grey and red label sticks out of the top of the enclosure.

Portable MSX2 Brings The Fun On The Go

Something of a rarity in the US, the MSX computer standard was rather popular in other parts of the world but mostly existed in the computer-in-a-keyboard format popular in the 80s. [Aron Hoekstra aka “nullvalue”] wanted to build an MSX2 of their own, but decided to build it in a period-appropriate luggable form factor.

This build really tries to make the computer as plausibly vintage as possible including an actual CRT for the display instead of using an easier to obtain and package LCD. Computing is accomplished with an Omega Home Computer MSX2 SBC by [Sergey Kiselev] which uses components that could have been found when the MSX computers were in production. While 3D printing wasn’t widespread in the 80s, we can assume any of the plastic parts like the internal mounts would have been injection molded instead.

An impressive number of different techniques were used to bring this computer to life including PCB design, 3D printing, CNC, and plenty of soldering. After some troubleshooting on the 50 pin cartridge connector and all the assembly, [Hoekstra]’s Mega Omega MSX2 Portable Computer makes for a very impressive reimagining of the MSX platform that feels like a product that might have actually existed at the time.

A Raspberry Pi Handheld Computer You Might Want To Use

Amid the many wonderful form factors being explored by the makers of cyberdecks, there’s one that’s emerged which harks back to an earlier generation of portable computers: the handheld pad with a keyboard. These units are typically around the size of a hardback book, with the upper half being a screen and the lower a keyboard. The latest to come our way is from [Richard Sutherland], and it’s a very tidy pad computer indeed.

Inside the well-designed layered 3D printed case is the frequently-chosen Raspberry Pi 4, along with a PiSugar power supply board and 5,000 mAH battery and a 4.3″ touchscreen display. The keyboard has seen a lot of care and attention, featuring high-quality tactile switches that follow the Miryoku keyboard layout. He says it’s a thumb-typing keyboard, but anyone looking for more can either adapt the design to their liking or simply plug in an external board when faster typing is needed.

We like the pad computer trend as it offers useful computing power in a far more convenient format than a laptop, and we think this is a particularly nice one. It would be nice to see where people take this design, and who knows, we might give one a try for writing some Hackaday articles. If you’d like to see more pad computer goodness, we recently showed you one built in the shell of a classic Amstrad.

Retro Portable Computer Packs Printer For The Trip

Looking like it dropped out of an alternate reality version of the 1980s, the Joopyter Personal Terminal is a 3D printed portable computer that includes everything you need for life in the retro-futuristic fastlane: a mechanical keyboard, a thermal printer, and the obligatory tiny offset screen. It’s a true mobile machine too, thanks to it’s onboard battery and a clever hinge design that lets you fold the whole thing up into something akin to a PLA handbag. You won’t want to leave home without it.

This gorgeous machine comes our way from [Gian], and while the design isn’t exactly open source, there’s enough information in the GitHub repository that you could certainly put together something similar if you were so inclined. While they might not serve as documentation in the traditional sense, we do love the faux vintage advertisements that have been included.

The upper section of the Joopyter holds a Raspberry Pi Zero W (though the new Pi Zero 2 would be a welcome drop-in upgrade), an Adafruit PiTFT 2.8″ display, a CSN-A2 panel mount thermal printer, and a Anker PowerCore 15600 battery to keep it all running. On the opposite side of the hinge is a hand wired keyboard powered by a Raspberry Pi Pico running KMK.

Speaking of that printed hinge, [Gian] says it comes on loan from [YARH.IO], which Hackaday readers may recall have produced a number of very slick 3D printed portable Linux machines powered by the Raspberry Pi over the last couple of years.

Triple Monitor Luggable PC Is An All In One Powerhouse

[Matt] from [DIY Perks] has made a name for himself building nice custom computing machines, and his latest triple-monitor luggable PC (video after the break) is sure to give most high-performance desktop machines a run for their money.

The large central monitor folding laptop monitors mounted vertically on either size look impressive, but only just scratches the surface of this build. Hidden behind aluminum panels are Ryzen 5950X CPU and RTX 3080 GPU with water cooling, 64 GB of RAM, and two 8 TB SSDs. A set of high-quality speaker drivers, subwoofer, and audio amps is also included. All this hardware pulls about 600 W of power from a large DC-DC converter block, which in turn receives power from either a pair of onboard AC-DC converters or a 16 V – 63 V DC source, like a battery system.

To mount everything to the back of the main monitor, [Matt] created 3D printed adaptor blocks with threaded inserts which slide under existing hooks on the back of the monitor. Aluminum angles screw to these blocks to cover the edges of the display panel, together with a large mounting plate with pre-drilled holes to mount all the components on standoffs. A set of adjustable and removable legs mount to the side of the PC. A hinged door in the back cover allows storage space for a keyboard and mouse during transport. When folded, the laptop monitors don’t fully cover the main monitor, so [Matt] created a leather cover that doubles as a cable and accessory organizer.

Whether its dual screens and an integrated SDR, or a rotating-folding screen, there is no shortage of ways to build a portable powerhouse. Continue reading “Triple Monitor Luggable PC Is An All In One Powerhouse”

Handheld Hackintosh Runs Mac OS On LattePanda

We’ve seen a huge influx of bespoke portable computers over the last couple of years thanks to availability of increasingly powerful single-board computers. The vast majority of these have been ARM powered using something like the Raspberry Pi 4, and naturally, run Linux. Only a handful have run on x86 hardware, usually because whoever built it wanted to be able to run Windows.

But this handheld x86 Hackintosh running the latest Mac OS on the LattePanda Alpha is truly something unique. Creator [iketsj] claims it to be a world’s first, and after a bit of searching, we’re inclined to agree. While others have installed Mac OS on the LattePanda to create Hackintosh laptops, this would indeed appear to be the first handheld computer to utilize this particular hardware and software blend.

Like other custom portables we’be seen, this one starts with a 3D printed enclosure. The overall design reminds us a bit of the YARH.IO we covered last year, and even borrows the trick of reusing the membrane and PCB of one of those miniature keyboard/pointer combos. Which in this case ends up being especially important, as in keeping with Apple’s own portable Mac OS machines, the screen on this handheld doesn’t support touch.

We especially like how the integrated Arduino on the LattePanda is being used in conjunction with some MOSFETs to control power to the handheld’s LCD, keyboard, and fans. While it sounds like the fans are currently running at full throttle, [iketsj] mentions he does intend on adding automatic speed control in the future. A dedicated “chassis controller” like this makes a lot of sense, and is something we imagine will only become more common as these portable builds become increasingly complex.

Now that we’ve seen a custom portable computer running Mac OS, are we due to see a whole new wave of cyberdecks sporting Cupertino’s software in the future? Maybe not. As [iketsj] points out at the end of this video, Apple’s switch from x86 to their own in-house silicon will almost certainly mean the death of the Hackintosh project within the next few years, bringing a fascinating era of computer hacking to a close.

This Stackable Pi Portable Is Ready To Rumble

The proliferation of desktop 3D printing and powerful single-board computers like the Raspberry Pi has given rise to an absolute explosion of small bespoke computing devices. Whether or not you think these cobbled together devices are close enough to Gibson’s original vision to call them cyberdecks, it’s a remarkable shift from the norm that brings us closer to the “High Tech, Low Life”  philosophy so prevalent in cyberpunk literature and films.

[Jay Doscher] has been on the front lines of this movement for some time now, producing several very popular designs. His latest creation leans hard into the more utilitarian aspects of the cyberpunk ethos, inspired more by the grit of The Expanse than the lusciously upholstered interiors of Star Trek’s Enterprise-D. The culmination of lessons learned over the last several years, the new Kuiper Deck is cheaper and easier to build than his previous designs, thanks at least in part to the fact that you no longer need to go out and get an expensive Pelican case.

Like his previous designs, the Kuiper Deck makes extensive use of 3D printed components. But this time around, [Jay] is using an array of smaller pieces that are bolted together on an acrylic front panel. This not only means the project is compatible with a wider array of machines, such as the Prusa Mini, but it’s also easier to print as larger parts have an annoying tendency to warp. The downside is that you’ll need some way to get the acrylic panel cut to shape, though you can buy one through him if you don’t have any way to get it made locally.

In place of the Pelican case his previous designs used as an enclosure, [Jay] has found a heavy-duty stackable plastic tote available from McMaster Carr for $12 USD. It’s not particularly nice looking, nor is it waterproof. But that’s also sort of the point. If you’re just trying to put together a small computer that you can toss around the shop and not have to worry about breaking, the Pelican case was always a bit overkill.

The electronics bill of materials is similarly sparse, comprising mainly of the Raspberry Pi 4, a cooling fan, and a 10 inch LCD from Pimoroni. Everything gets screwed to the rear of the panel and connected with pre-made cables, making assembly very simple. That said, there’s still plenty of room inside the case for custom hardware should you want to put something custom together such as a mobile software defined radio rig.

[Jay] created the original Raspberry Pi Field Unit in 2015, but it wasn’t until he unveiled the revised Raspberry Pi Recovery Kit in 2019 that the idea of sticking a Raspberry Pi into a Pelican case became something of hacker meme. It sounds like the Kuiper Deck is going to be his final word on the subject for now, but it’s a safe bet we’ll be seeing folks putting together similar builds for years to come.
