2022 Cyberdeck Contest: A Wrist-Worn Deck With A Hybrid Interface

October 16, 2022 by Dan Maloney 4 Comments

You’d think that now that the 2022 Cyberdeck Contest is wrapped up, we’d stop writing about it. Sorry, but no — there were so many great entries that we just can’t help but keep focusing on them. And this wearable hybrid interface cyberdeck has a look we love so much that we can’t resist spotlighting it.

We wouldn’t go so far as to call the “hgDeck” a PipBoy, but [Igor Brkić]’s wrist-worn deck certainly bears some similarity with to the Fallout-famous terminal. In fact, the design for this one is based on his earlier hgTerm Raspberry Pi mini-laptop, which honestly would have made a great entry all by itself. But while the two version shares some similarities, the hgDeck puts a serious twist on the form factor. In the stowed configuration, the Pi Zero W puts the main display, a 3.5″ Waveshare TFT, to work using the resistive touchscreen interface. But with the flick of a finger, a motor flips the monitor up on a set of pantograph linkages, which exposes a compact Bluetooth keyboard. Another touch stows the screen and returns you to touchscreen-only operation.

There were a fair number of wrist-worn decks in the contest’s final results, and while this one didn’t win, [Igor]’s build has got to be one of the cooler designs we’ve seen, one that almost seems practical in the real world.

2022 Cyberdeck Contest: Picking The Best Of The Best

October 13, 2022 by Tom Nardi 15 Comments

Given how many incredible builds we’ve covered over the last couple of years, we knew that an official Cyberdeck Contest would certainly receive some impressive entries. But never in our wildest dreams could we have predicted that more than 100 decks would end up crossing the finish line, or that of them, the vast majority would be never-before-seen designs. In fact, the response to this contest was so overwhelming that the judging process took far longer than we originally anticipated.

Ultimately, we decided that there were simply too many phenomenal builds entered into the contest to award $150 Digikey spending sprees to just three of them. So as an added bonus, we’ve rustled up some $50 Tindie gift certificates that will go to the four special category honorable mentions.

With that, let’s take a look at the cyberdecks that took top honors as decided by our panel of judges.

Retro Speaker Becomes The Perfect Micro PC

October 5, 2022 by Jenny List 6 Comments

We’ve seen many cyberdecks and home built computers in our time here at Hackaday, but we’ve not seen many so tiny and so neatly built as this one from [Carter Hurd]. It takes the form of a tiny retro PC with a working display and keyboard, and we like it a lot.

The diminutive computer started life as a neat little retro themed Bluetooth speaker that a company bravely sent him for a project when he declined the chance to review it. Out came the speaker and electronics, and in went a USB Blackberry keyboard with a custom made bezel where the speaker’s keys had been.

The display is a 4″ LCD designed for a Raspberry Pi, and somewhat incredibly, he trimmed its corners to fit into the case. Making the curved CRT-style display front was achieved with vacuum form plastic, and a new display bezel was 3D printed.

A full-size Raspberry Pi fits in the base of the unit, and here he admits that it’s not the tidiest job. Perhaps a Pi Zero would have been more unobtrusive, but either way from the top and front it’s a really cute little machine. It may not be the only tiny cyberdeck we’ve seen, but it’s certainly a well-built one.

Watch on the wrist, with all the sensors facing the camera. There's a lot of them, and a lot of wires of all kinds tying everything together.

2022 Cyberdeck Contest: IP00-Minus, A Daring Wearable

October 4, 2022 by Arya Voronova 10 Comments

[Rob]’s IP00-Minus watch stands out on the Cyberdeck Contest project list page; it’s clear he decided to go a different path than most other hackers, and we can certainly see the advantages. For example, if there’s no case, there’s no need to redesign it each time you want to add a module — and [Rob] has added many, many modules to this watch.

Picking between regular LCD, memory LCD, and OLED displays can be a tricky decision to make when planning out your gadget, so he just added all three. The CircuitPython firmware initially attempted to resist the trio, but was eventually defeated through patching. Jokes aside, we can almost feel the joy that [Rob] must have felt after having put this watch on for the first time, and this project has some serious creative potential for a hacker.

[Rob] has been focusing on day-to-day usability first and foremost, with pleasantly clicky encoders, impeccable performance of its watch duty, unparalleled expandability, and comfortable wrist fit — it provides a feeling no commercial wearable could bring.

Out of the myriad of sensors, the air quality sensor has been the most useful so far, letting him know when to open a window or leave a particularly crowded place. The ESP32-S3 powered watch has been quite a playground for [Rob]’s software experiments, and given the sheer variety of hardware attached, we’re sure it will bring unexpected synergy-driven ideas. Plus, it’s no doubt a great conversation starter in nerd and non-nerd circles alike.

Good things happen when you give hackers a wrist-worn watch full of sensors, whether it’s a particularly impressive event badge, a modified firmware for an open source smartwatch, or a custom piece that pushes the envelope of DIY hardware.

2022 Cyberdeck Contest: A Chorded-Keyboard Wearable Cyberdeck

October 1, 2022 by Dan Maloney 10 Comments

Those of us who are unreformed hunt-and-peck typists are often baffled by the keyboard skills of those with more formal training. Home row? Specific fingers for specific keys? The mind boggles. And chorded keyboards? That’s straight-up witchcraft!

But, there are times when only a chorded keyboard will do, such as when you want to build a wrist-wearable cyberdeck like this one. It’s called the ComputeDeck-B3, and it comes to us from [Nate Damen], better known as someone who goes around with a TV on their head, which sort of fits with the total device immersion this cyberdeck enables.

The deck is designed to fit on the forearm in the position of function — basically, the posture your arm, wrist, and hand take on naturally when everything is relaxed. There’s a small display mounted at a good angle for viewing, but the star of the show is the keyboard. The fingers slip inside a slot to find three mechanical key switches positioned for each finger. It looks like the idea is to use the finger pad, fingertip, and fingernail to press each key, and then to press different combinations of keys to make specific characters. The thumb isn’t left out of the action; there’s a five-position “hat switch” located right where the thumb naturally falls, to add to the input possibilities. The short video below gives a tour and some background on design goals, and why this isn’t really a PipBoy.

For as much as chording isn’t our thing, we can see how this could work for input on the fly. And we have to compliment [Nate] on paying attention to ergonomics here, even though extending the fingers to press the nail buttons seems like a somewhat unnatural movement. We’d love a follow-up on this after he’s had some time to put it through its paces. Continue reading “2022 Cyberdeck Contest: A Chorded-Keyboard Wearable Cyberdeck” →

2022 Cyberdeck Contest: The Oscilloscope Deck

September 30, 2022 by Jonathan Bennett 27 Comments

When [Jak_o_Shadows] Siglent Oscilloscope died, he didn’t just mourn the loss, he saw an opportunity. See, he had a Raspberry Pi 400 already set aside for a cyberdeck build, and he just scored a novel case. Most of the insides of the old scope came out, but the screen and control knobs live on in the new build. An HDMI-to-LVDS adapter brought the screen back to life, and the control knobs are a work-in-progress. Added to the case are some fun goodies, like a LimeSDR, connected to the old scope inputs. A PL2303 is wired to the serial port, making that functional, too. It’s a very nice touch that the build retains the original scope’s functions this way.

There’s plenty of 3d-printed goodness, like some internal brackets to hold things in place. The real star of the show is a 3d-printed hinge, holding the scope and Pi 400 together and making the whole package portable. There’s a neat tip, too, in that the Pi 400 has a huge integrated heat sync under the keyboard. It’s just a sheet of metal, so you can drill and tap it as mounting points. Cool!

This is a nifty build, and certainly a worthy deck for jacking-in to whatever you’re working on. And re-purposing an oscilloscope is a nice aesthetic. If [Jak_o_Shadows] can just get the front array of buttons and knobs working with his STM32, this will be a killer deck, the envy of console cowboys everywhere.

This Computer Is Definitely Not A Toy

September 30, 2022 by Jenny List 6 Comments

If you’ve ever eyed up a kids laptop and wondered whether it could take an upgrade with a single board computer, you’re not alone. [Labz] have taken a couple of Brazilian Max Steel toy computers from a decade or more ago, and made them into usable if unconventional portable computers (Brazilian Portuguese, but YouTube’s subtitle translation is your friend).

The computers are similar to the ones you may be familiar with from the likes of VTech, a QWERTY keyboard and fairly conventional form factor but with a tiny monochrome LCD and a few built-in games. In the video below the break we see both the laptop and desktop variants butchered with a rotary tool to receive new larger screens, with the laptop getting a Raspberry Pi and the desktop getting a small form factor PC. The laptop needed a 3D printed extension to make extra space, while the desktop received a PCI Express extension cable for a video card. Finally, an Arduino took care of the keyboard.

The cherry on the cake for this video comes at the end, when they find the now-grown-up kid from the original advert. Meanwhile, kids computers have featured here before a few times.
