A Typewriter For The Paperless Age

Writing is, as any of the Hackaday crew will tell you, a task which requires concentration. For your best work there’s a need to be in that elusive Zone, and for some that means making the experience as distraction free as possible. For them there’s an entire class of minimalist word-processors and text editors which reduce the UI to nothing more than the text. [Adam Blumenberg] has taken this a step beyond software with his digital typewriter, a single-purpose Raspberry Pi-based cyberdeck that serves only for distraction-free writing.

There’s not a lot in the way of descriptive text at the above link but in a way there doesn’t need to be as the photographs tell the story. A mechanical keyboard and a wide but not very tall display fit with the Pi in a fairly rudimentary wooden case, and running Focuswriter it leaves very little in the way of distraction. In that sense it’s not quite so much a cyberdeck in its application as something more like the smart digital typewriters from a few decades ago without the printer, but we can see that it makes for a very handy writing implement. Sadly the job of writing for Hackaday requires constant access to online sources on a larger screen, or we’d be tempted to try one ourselves.

The one-purpose writing computer is an idea we’ve seen before from time to time, for example in this one with an e-paper display.

2023 Cyberdeck Challenge: The Best Decks On The Net

It was an easy decision to run a Cyberdeck Challenge in 2023 — after all, it was far and away one of our most popular contests from last year. But what was much harder was sorting out the incredible array of bespoke computers that readers have been sending in for the last few months.

Our judges have painstakingly whittled down the list of entries to get our top three winners, each of which will be awarded $150 in credit from the good folks over at DigiKey. But there were simply too many fantastic custom computers in the running to let everyone else go home empty-handed, so we’ve decided to also break out some $50 Tindie gift cards for the decks that best exemplified this year’s special categories.

Without further ado, let’s take a tour through the judge’s top picks for this year’s Cyberdeck Challenge!

This CRT Luggable Makes Sense

There was a time when portable computing meant not a svelte laptop but a suitcase-sized machine that was really a slimmed-down desktop with a small CRT incorporated int he same box. They were heavy and unwieldy, but the computing compromises of using one at the time were less than with what served for more portable machinery. It’s a form factor which understandably has long ago disappeared, but that hasn’t stopped [Sdomi] from reviving it with a machine that packs plenty of modern computing power.

It’s a project that started with a monitor, a diminutive green-screen model which had previously adorned a CNC machine. It’s a composite model, so it’s driven from a VGA-to-composite converter. The computing power comes from a thin-client board that packs an up-to-date AMD Ryzen processor and 32 GB of memory, and the case is manufactured from oriented strand chipboard.

The result is a chunky but definitely practical and usable take on a portable cyberdeck, with the caveat that a composite monitor will not deliver the resolution some of us might be used to. We have to admit rather liking it, there’s nothing like the curved glass of a CRT.

It’s by no means the only up to date luggable we’ve seen, though more often now they feature an LCD.

2023 Cyberdeck Challenge: KOAT0 Portable Terminal

We’ve had cyberdecks as part of the scenery for long enough now that there are a series of common elements that appear across many different builds. The Raspberry Pi, for instance, or the mechanical keyboard, with a 3D printed body. [RobsonCuto]’s KOAT0 Portable Terminal has some of those in a particularly slim and neat design. The orange and grey color scheme is great really pops. Where this deck really shines though, is the display.  He’s eschewed LCDs or OLEDs, even CRTs, and gone for an unusual choice in a dot-matrix VFD.

The VFD in question is commonly available on AliExpress where it appears to be used for displaying Chinese characters. It’s not an obvious choice for a cyberdeck, so once the tidy-looking case is complete the real challenge in this project becomes how to drive it from the Pi. To that end, he appears to have some kind of text output working but still needs to complete a framebuffer driver. We applaud the effort and we really like the display.  We’re curious as to how its meager resolution might best be used in a Linux device.

All in all, this is a ‘deck we’d be happy to use ourselves if it were an option. We particularly like the on-the-arm style of use, and we’re pretty sure it’s the first time we’ve seen one of these displays on these pages.

2023 Cyberdeck Challenge: CyberTapeDeck

There seem to be two schools of thought when it comes to picking an enclosure for your cyberdeck project: you either repurpose the carcass of some commercially produced gadget, or you build a new case yourself. The former can lead to some very impressive results, especially if your donor device is suitably vintage, but the latter is far more flexible as the design will be based on your specific parameters.

But for the CyberTapeDeck, [Matthew] decided to take a hybrid approach. The final product certainly looks like it’s built into a 1980s portable tape deck, but on closer inspection, you’ll note that the whole thing is actually 3D printed. The replica doesn’t just nail the aesthetics — it also includes the features you’d expect from the real thing, including an extendable handle and functional buttons which the internal Raspberry Pi 3 sees as a macropad thanks to an Arduino Pro Micro.

A seven inch LCD stands in for the tape door, and while it unfortunately doesn’t look like [Matthew] was able to replicate the opening mechanism to angle the display, you can at least stand the whole thing on its end to provide a more comfortable viewing experience.

[Matthew] says one of the intended purposes for this cyberdeck is to get his son excited about working with electronics and programming, so in a particularly nice touch, he’s mounted a terminal block over the “speaker” that ties into the Pi’s GPIO pins. This provides a convenient interface for experimenting on the go, without getting tangled up in exposed wiring.

We appreciate that [Matthew] has released the STL files for all of the printed parts, because even though it makes a great cyberdeck, the design is begging to house a faux-retro media player.

2023 Cyberdeck Challenge: Modular Cyberdeck Creation Kit

We were fortunate to run into [Sp4m] at DEFCON31 and see his Modular Cyberdeck Creation Kit in person. In fact, he was wearing it around the hallways like a rogue decker in search of fellow runners. Holding the unit feels like a serious tool because of its weight, mainly from the battery. Everything hangs from a single-point sling on a metal handle, probably from the cabinetry aisle, and we could move silently and comfortably. The sling is firearm-rated, which is appropriate since he has a printed Weaver rail on top. It just needs a flashlight/laser combo.

[Sp4m] aims to create printable parts that combine any on-hand materials into a usable cyberdeck. In this iteration, he uses a wired Apple keyboard and trackpad he found in the trash, so we have to assume he works in IT. Most of the trackpad is covered, but enough is accessible to scroll and maneuver the mouse, saving almost six inches. The Steam deck is the current head but is removable so that this hardware collection can work for many USB-C tablets without fuss.

The eye-catching white/orange is no accident and may earn it a top spot in the Icebreaker category of the 2023 Cyberdeck Contest. The judges are currently deliberating, so keep an eye out for an announcement about the winners shortly.

2023 Cyberdeck Contest: A Toddler’s Cyberdeck

[Josh] has a child and what do children like more than stuffing random things into their mouths? Pushing buttons, twiddling knobs, and yanking things of course! So [Josh] did what any self-respecting hacker would do and built his little man a custom cyberdeck.

The build follows the usual route of some electronics wedged into a pelican-style waterproof case — which is a good choice for this particular owner — a repurposed all-in-one LCD video player in the lid and a bunch of switches in the base. The player is apparently a V100-base SBC the likes of which are used in shops for those annoying looping promotional videos, but it doesn’t really matter if all it’s doing is being a focus point.

There is no connection from the base to the ‘display’ but that doesn’t matter here. The base is the fun part, with lots of old-school toggle switches and rotary knobs to play with and a load of LEDs to flash in mysterious ways. The guts of this are controlled via an Arduino Mega 2560, with copious amounts of hot glue on display in true hacker style. On the coding side of things, [Josh] used ChatGPT to produce the code from his prompting and Wokwi  to simulate it before deployment to the hardware.
