DevTerm Beats Cyberdeck Builders To The Punch

December 8, 2020 by Tom Nardi 45 Comments

What makes a cyberdeck? Looking as though it came from an alternate reality version of the 1980s is a good start, but certainly isn’t required. If you’re really trying to adhere to the cyberpunk ethos, any good deck should be modular enough that it can be easily repaired and upgraded over time. In fact, if it’s not in a constant state of evolution and flux, you’ve probably done something wrong. If you can hit those goals and make it look retro-futuristic at the same time, even better.

Which is why the Clockwork DevTerm is such an interesting device. It ticks off nearly every box that the custom cyberdeck builds we’ve covered over the last couple years have, while at the same time being approachable enough for a more mainstream audience. You won’t need a 3D printer, soldering iron, or hot glue gun to build your own DevTerm. Of course if you do have those tools and the skills to put them to work, then this might be the ideal platform to build on.

With a 65% QWERTY keyboard and widescreen display, the DevTerm looks a lot like early portable computers such as the TRS-80 Model 100. But unlike the machines it draws inspiration from, the display is a 6.8 inch 1280 x 480 IPS panel, and there’s no pokey Intel 8085 chip inside. The $220 USD base model is powered by the Raspberry Pi Compute Module 3, and if you need a little more punch, there are a few higher priced options that slot in a more powerful custom module. Like the Waveshare Pi CM laptop we recently looked at, there’s sadly no support for the newer CM4; but at least the DevTerm is modular enough that it doesn’t seem out of the question that Clockwork could release a new mainboard down the line. Or perhaps somebody in the community will even do it for them.

Speaking of which, the board in the DevTerm has been designed in two pieces so that “EXT Module” side can be swapped out with custom hardware without compromising the core functionality of the system. The stock board comes with extra USB ports, a micro USB UART port for debugging, a CSI camera connector, and an interface for an included thermal printer that slots into a bay on the rear of the computer. Clockwork says they hope the community really runs wild with their own EXT boards, especially since the schematics and relevant design files for the entire system are all going to be put on GitHub and released under the GPL v3.

They say that anything that sounds too good to be true probably is, and if we’re honest, we’re getting a little of that from the DevTerm. An (CPU BLOBs aside!) open hardware portable Linux computer with this kind of modularity is basically a hacker’s dream come true, and thus far the only way to get one was to build it yourself. It’s hard to believe that Clockwork will be able to put something like this out for less than the cost of a cheap laptop without cutting some serious corners somewhere, but we’d absolutely love to be proven wrong when it’s released next year.

AlphaSmart Neo Teardown: This Is The Way To Write Without Distractions

November 5, 2020 by Kristina Panos 52 Comments

History will always have its in-between technologies — that stuff that tides us over while the Next Big and Lasting Thing is getting the kinks worked out of it. These kinds of devices often do one thing and do it pretty well. Remember zip drives? Yeah you do. Still have mine.

The halcyon days of the AlphaSmart NEO sit in between the time where people were chained to heavy typewriters and word processors and the dawn of on-the-go computing. Early laptops couldn’t be trusted not to die suddenly, but the NEO will run for 700 hours on three AAs.

The NEO stands for the freedom to get your thoughts down wherever, whenever, without the need for a desk, paper, ink, ribbons, power cords, and the other trappings that chain people indoors to flat surfaces. And that’s exactly what was so tantalizing to me about it. Inspiration can truly strike anywhere at any time, so why not be prepared? This thing goes from off to blinking cursor in about a second and a half. There’s even a two-button ‘on’ option so you don’t run the battery down or accidentally erase files while it’s in your bag.

These might be the world’s greatest scissor switches.

L-R: DC power, IR, USB-B, and USB-A for connecting to a printer.

I bought this funny little word processor a few years ago when I wanted to attempt NaNoWriMo — that’s National Novel Writing Month, where you write 50,000 words towards a novel, non-fiction book, or short story collection in any genre you want. It averages out to 1,667 words a day for 30 days. Some days it was easy, some days it was not. But every non-Hackaday word I typed that month was on this, my Mean Green Words Machine.

Simplifying The Ruggedized Raspberry Pi Portable

October 19, 2020 by Tom Nardi 37 Comments

Over the last year we’ve seen a wave of portable computer builds that center around the Raspberry Pi taking up residence inside a commercial heavy-duty storage case. It’s not hard to see why; whether you spring for the Pelican case or get a cheaper alternative, these water-tight cases are far stronger than anything you’re going to 3D print or otherwise cobble together in the home shop. Especially if you can avoid popping any holes in the side.

Inspired by these builds but looking to make it even easier and cheaper to roll your own version, [Dmitry] recently took the wraps off of what he calls the Militarish Pi. You don’t need a CNC to cut out any face plates or a 3D printer to create an internal framework for all your components. You could even do it without soldering anything, if you really wanted to. Short of just buying one of these rigs pre-built from somebody, it’s hard to imagine it could get much easier than this.

Most of the effort involves cutting the PVC foam sheet that holds the Raspberry Pi, battery pack, and the driver board for the LCD in the bottom of the $15 USD case [Dmitry] managed to track down on AliExpress. The “carbon fiber” sticker he put on the PVC sheet won’t do much for the structural integrity of the build, but it sure looks nice. Of course if you have access to the appropriate tools, you could certainly cut the plate out of something stouter. As for the display, the nine inch LCD is perfectly sized to press fit into the lid.

Rounding out the build, [Dmitry] found a cheap Android phone case that included a tiny USB keyboard which plugs right into the Pi and he’s looking to add a BlackBerry trackball to the setup down the line. We especially like the large open area that he’s kept around the Raspberry Pi’s ports that allow you to easily hook up to the network or plug in a flash drive. It could also be a nice compartment to keep your RTL-SDR for some mobile radio work.

For those that don’t mind spending name-brand money and have access to a 3D printer, the Raspberry Pi Quick Kit by [Jay Doscher] is another great way to get yourself a rough and tumble Pi without reinventing the wheel.

YARH.IO Is The Hackable Pi Portable Of Our Dreams

September 3, 2020 by Tom Nardi 23 Comments

Less than a decade ago, building a completely custom portable computer was more or less out of the question. Sure you could have cobbled something together with a Gumstix board and the dinky NTSC/PAL screen pulled from a portable DVD player, but it wouldn’t exactly have been a daily driver. But now we have cheap high definition LCD panels, desktop 3D printers, and of course, the Raspberry Pi.

We’ve seen these elements combined into bespoke personal computing devices too many times to count now, but very few of them can compare to the incredible YARH.IO. It’s been designed from the ground up for easy assembly and customization; you don’t have to worry about getting custom PCBs made or tracking down some piece of unobtanium hardware. Everything inside of the 3D printed enclosure is an off-the-shelf module, needing little more than the occasional scrap of protoboard to tie them all together.

One glance at the rugged design of the YARH.IO, and it’s clear this device wasn’t meant to live on a shelf. Whether it’s getting tossed around the workbench or thrown into a bag on the way to a hacker con, the militarized design of this portable is ready for action. Using appropriately strong materials such as PETG and ABS, we have no doubt the enclosure will survive whatever the on-the-go hacker can throw at it.

But what’s arguably the best feature of the YARH.IO also happens to be the least obvious: the modular design of the enclosure allows you to remove the lower keyboard section and use it as a battery powered Linux tablet (albeit a rather chunky one). Whether the keyboard is attached or not, you still have access to the Pi’s expansion header thanks to a clever pass-through.

Like with the Mil-Plastic that [Jay Doscher] released recently, we know these 3D printed kits will never be as strong as the real military gear they’re emulating. But let’s be realistic, none of us keyboard warriors will be taking them into an actual battlefield anytime soon. What’s more important is that their modular construction allows them to be easily modified for whatever the user’s needs might be. With as far as the state-of-the-art in DIY bespoke computing as come in the last decade, we can’t wait to see what the future holds.

Burning Chrome

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

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.
