You want a good project that combines multiple disciplines, gives you something useful in the end, and will certainly wow the muggles? Or do you simply need a custom rig with which to “jack in” to “cyberspace”? How about building your own luggable, portable, computer with some style — your own cyberdeck?

Coming to you from the fertile world that William Gibson created in “Neuromancer”, “Count Zero”, and “Mona Lisa Overdrive”, cyberdecks were the portable computers that the heroes and anti-heroes roaming the Sprawl would use to connect to what was essentially the Internet. Since we’re already living in the era where large portions of the world are controlled by vast corporations, we spend our entire lives online, and machine intelligence is poised to become sentient, you might as well get building.

We’ve seen a number of great examples of cyberdeck builds, and they’re all special in their own way, but there are common features uniting them all. First, you’ll need a screen, a portable computer brain, some batteries, and a nice keyboard. The good news is that all of the above have become eminently available, even inexpensive, in the last few years.

Discipline #1 is that of the case modder. You’re designing your ideal portable computer, after all. It’s got to look good, and we don’t mean that black, boxy ThinkPad look. If you’ve got a 3D printer, and maybe a willingness to spray paint, the world is your oyster here.

Discipline #2 is that of the keyboard builder. You’re not going to want to enter the Matrix with anything less than a pleasant typing interface. Again, 3D printing, laser-cutting, or CNC milling your own keyplate and building yourself a keyboard from scratch is a viable option, but there are tons of Bluetooth and USB keyboard options if you want to cut corners, or find one you really like.

Discipline #3 is the software hacker. Putting together exactly the right set of software, setting up the system to do what you want, and getting that sweet background screen just right are the last steps to making yourself at home in Cyberspace.

With so much latitude to introduce your own design ideas into your bespoke luggable, no two will be alike. Mine’s going to have programming ports for every microcontroller I frequently use, a decent speaker, maybe a variable power supply, and probably some reasonable amount of LED bling. What’s going to be on yours?

Join The Movement With This Mini Cyberdeck

June 5, 2020 by Tom Nardi 5 Comments

The global pandemic has given many people a lot more time at home, which has undoubtedly pushed an untold number of projects over the finish line. Unfortunately, it’s also disrupted global commerce and shipping to the point that getting parts can be a lot harder than we’d like. Which is why [facelesstech] decided to put together this exceptionally mobile cyberdeck out of things he already had laying around.

Now to be fair, his parts bin is perhaps a bit better stocked for this kind of thing than most. He’s built a couple of Raspberry Pi portables already, so the Pi Zero W, display, and battery management board were already kicking around. He just had to come up with a new 3D printed enclosure that holds it all together with a little bit of cyberpunk flair.

To that end, he’s done an excellent job of documenting the build and has released the STL files for the 3D printed components. All things considered, we’d say this is probably the most approachable cyberdeck design currently available; if you’ve been wondering what all the fuss is about with these bespoke little computers, this is an ideal project to get started with.

Keep in mind that the idea of a cyberdeck is to build something custom for yourself, so there’s no need to copy this build exactly. If you’re short on parts, you could forgo the battery powered aspect and just keep it tethered. The superfluous (but very cool) GX12 connectors could certainly be deleted as well, although at serious stylistic cost. You’ll probably need to order the specific keyboard that [facelesstech] designed the lower half of the device around, but it’s common enough that it shouldn’t be hard to track down. No matter which way you take it, this design is a great base to start from.

If you’re looking for something a bit more substantial and have the filament to burn, you might take a look at the VirtuScope to fulfill your offset screen needs.

Teardown: VTech Whiz Kid Luggable Computer

April 27, 2020 by Tom Nardi 47 Comments

Back in the early 1980s, hotshot business types on the go would have used what were referred to at the time as portable computers from companies like Osborne or Kaypro. Due to the technical limitations of the era these so-called “luggables” were only slightly smaller and lighter than contemporary desktop computers, but they had integrated displays and keyboards so they were a bit easier to move around. A few years later the first generation of laptops would hit the market, and the portables predictably fell out of favor. Today they’re relatively rare collectors items; a largely forgotten first step in the steady march towards true mobile computing.

Which makes the 1984 edition of VTech’s “Whiz Kid” educational computer an especially unique specimen. The company’s later entries into the series of popular electronic toys would adopt (with some variations) the standard laptop form factor, but this version has the distinction of being what might be the most authentic luggable computer ever made for children. When this toy was being designed it would have been a reflection of the cutting edge in computer technology, but today, it’s a fascinating reminder that the latest-and-greatest doesn’t always stick around for very long.

The classic luggable hallmarks are all here. The flip down keyboard, the small and strangely offset display, there’s even lugs on the side to attach an included strap so the youngster can sling it over their shoulder. On the other hand, the fact that it’s just a toy allowed for some advantages over the real thing: it can actually run on battery power, and is quite lightweight relative to its size.

When we last took a peek inside one of VTech’s offerings, we found a surprisingly powerful Z80 machine that was more than deserving of its PreComputer moniker. But that BASIC-compatible design hailed from the late 80s, and was specifically marketed as a trainer for the next generation of computer owners. Will the 1984 Whiz Kid prove to have a similar relationship to its adult counterparts, or does the resemblance only go skin deep? Let’s find out.

A Luggable Computer For The Raspberry Pi Era

January 10, 2020 by Tom Nardi 25 Comments

Today, computers are separated into basically two categories: desktops and laptops. But back in the early 1980s, when this ideological line in the sand was still a bit blurry, consumer’s had a third choice. Known as “portable computers” at the time, and often lovingly referred to as luggables by modern collectors, these machines were technically small enough to take with you on a plane or in the car.

Improvements in miniaturization ultimately made the portable computer obsolete, but that doesn’t mean some people still don’t want one. [Dave Estes] has been working on his own modern take on idea that he calls Reviiser, and so far it looks like it checks off all the boxes. With the addition of a rather hefty battery pack, it even manages to be more practical than the vintage beasts that inspired it.

In the video after the break, [Dave] walks us through some of the highlights of his luggable build, such as the fold-down mechanical keyboard, gloriously clunky mechanical power switches, and the integrated touch screen. We also really like the side-mounted touch pad, which actually looks perfectly usable given the largely keyboard driven software environment [Dave] has going on the internal Raspberry Pi 4. With a removable 30,000 mAh battery pack slotted into the back of the machine, he’ll have plenty of juice for his faux-retro adventures.

[Dave] mentions that eventually he’s looking to add support for “cartridges” which will allow the user to easily slot in new hardware that connects to the Pi’s GPIO pins. This would allow for a lot of interesting expansion possibilities, and fits in perfectly with the Reviiser’s vintage aesthetic. It would also go a long way towards justifying the considerable bulk of the machine; perhaps even ushering in a revival of sorts for the luggable computer thanks to hardware hackers who want a mobile workstation with all the bells and whistles.

Right now there isn’t a lot of detail on how you can build your own Reviiser, but [Dave] says more info will be added to his site soon. In the meantime, you can check out some of the similar projects we’ve seen recently to get some inspiration for your own Luggable Pi.

Building A Faux Retro Portable Computer

December 1, 2019 by Tom Nardi 48 Comments

The modern laptop has its origins in the mid to late 1980s, when shrinking computer hardware and improvements to battery technology finally made mobile computing practical. But before the now iconic clamshell form factor became the standard, there was a market for so-called “portable” computers. These machines often resembled pieces of luggage with keyboards attached, and even at their peak, they were nowhere near as practical as today’s ultra-thin notebook computers. But for the more nostalgic among us, these vintage portables do have a special sort of charm about them.

Looking to recapture some of that magic with modern components, [davedarko] has started working on his own Raspberry Pi portable computer. Just like those machines of yore, his build is designed to be a self-contained computing experience that you can lug around, but not exactly something you’d be popping open on the train. Its extruded aluminum frame holds the display, power supply, and audio hardware, with plenty of room to spare for additional hardware should he decide to pack in a couple hard drives or something more exotic.

The skeletal frame has plenty of room for activities.

We particularly like the 3D printed hinge and lock mechanism he designed that holds the keyboard closed against the front of the frame. Sufficiently ~~old~~ experienced readers will recall this particular feature being a defining characteristic of portables such as the Osborne 1 and Compaq Portable, and it’s great to see it included here. All it needs now is a leather handle on the side to complete the look.

[davedarko] still has some work ahead of him, as ultimately he’d like to completely enclose his computer’s frame with laser cut panels. But the build is certainly progressing nicely, and frankly, it’s already at the point where we’d have no problem pulling it out at the next hackerspace meetup. Between builds like this and the growing collection of cyberdecks we’ve covered recently, it looks as though 1980s design aesthetic is alive and well within the hacker community.

Amstrad Portable Gets A Modern LCD Transplant

October 30, 2019 by Tom Nardi 5 Comments

Playing classic games on the real hardware is an experience many of us enjoy, but sometimes the hardware is just a bit too retro for modern sensibilities. A case in point is the miserable monochrome LCD that was originally installed in the Amstrad PPC640 portable 8086 PC that [Drygol] recently picked up. He decided that his portable Amstrad sessions would be far more enjoyable if he swapped it out for a display that didn’t have 30+ years on the clock.

To quell the complaints of any of the vintage hardware aficionados out there, it’s worth mentioning that the original LCD was actually damaged and needed to be replaced anyway. Granted [Drygol] could have tried to find a contemporary panel to replace it with, but looking at the incredible before and after shots of the modded PPC640, it’s hard to argue he didn’t make the right decision by throwing a modern display into the otherwise largely original computer.

Getting the new LCD’s PCB ready for installation.

[Drygol] says he picked up a cheap 4:3 LCD TV on eBay, and as luck would have it, found that the new panel dropped perfectly into the original frame. Getting it buttoned back up required the removal of the RF can and all the female connections on the TV’s PCB, plus he had to cut some holes in the back of the display enclosure to mount the LCD’s controls, but overall it looks very stock.

Of course, getting the new LCD display in the original frame was only half the battle, it still needs to be connected up to the computer somehow. To get everyone playing nicely with each other, [Drygol] is using a commercially available MDA/CGA/EGA to VGA converter that is installed where the batteries would have gone originally. Wired to the PPC640’s external monitor connector, it allows him to drive the new display without having to use the original LCD interface.

[Drygol] has made something of a name for himself by performing some of the most impressive restorations and modifications of retro hardware in recent memory. From the unbelievable work that went into repairing a smashed Atari 800XL case to his gorgeous custom Amiga A500, his projects are sure to please the retro hardware lovers in the audience.

A Curiously Strong Z80 In Your Pocket

September 17, 2019 by Tom Nardi 42 Comments

Like many hackers, [Tom Szolyga] has soft spot for the venerable Z80. The number of instructions and registers made it relatively easy to program in ASM, and he still has fond memories of the refreshingly straightforward CP/M operating system he used to run on them back in the day. In fact, he loves Z80 computers so much he decided to build one that he could carry around in his pocket.

The result is the Minty Z80, so-called because it lives inside a tin formerly inhabited by every hacker’s favorite curiously strong mint. But the goal of this build wasn’t just to make it small, but also make it convenient to work with. [Tom] is using a ATmega32A to help interface the Z84C0008 microprocessor with the modern world, which allows for niceties such as support for a micro SD card. There’s no onboard USB-to-serial capability, but with an external adapter connected to the Minty’s header, it’s easy to use log into this microcosm of classic computing with a terminal emulator running on a computer or mobile device.

[Tom] has provided the schematics and Bill of Materials for the Minty Z80 on the project’s Hackaday.io page, but as of the latest update, he’s holding off on releasing the board files until he’s sure that all the bugs have been worked out. There’s no word yet if he found any show stoppers in the first iteration of the board design, but he’s posted a picture of the fully assembled miniature retrocomputer in all its glory which seems like a good sign.

The design of the Minty Z80 is similar to that of the Z80-MBC2 by [Just4Fun], but on an even smaller scale. It’s encouraging to see several projects leveraging modern design and components to prevent classic computing from becoming little more than a distant memory.
