Cyberdeck Contest 2022: Gibson Rev 001 Thinks Outside The Pelican Case

October 25, 2022 by Kristina Panos 5 Comments

As we’ve gushed previously in these pages, we saw an incredible turnout for our first-ever cyberdeck contest — so many cool ‘decks rolled in that it made judging them all quite the feat, and we would be remiss if we didn’t feature the favorites that, for whatever reason, didn’t make the cut. One of these is the aptly-named Gibson Rev 001 from [Gadjet].

This cyberdeck may be on the pocket-sized side of things, but don’t let that fool you, because it’s loaded with I/O and sensors galore. A Pimoroni Breakout Garden provides particle/smoke and pulse oximetry, temperature/pressure/altitude, an air quality sensor, and a UVA/UVB light sensor — plenty of feelers for judging conditions on the fly. As you might expect, the brains of the operation is a Raspi 4, which is running Twister OS.

We love the dual-display thing going on with the 7″ touchscreen and the color e-ink display — really gives it a cobbled-together-yet-polished, futuristic feel. May the rest of the post-apocalypse gadgetry have such clean lines and cheerful colors (if that’s what you’re into).

2022 Cyberdeck Contest: QAZ Personal Terminal

October 22, 2022 by Navarre Bartz 9 Comments

The slabtop form factor has had a resurgence in the cyberdeck community, and [Greg Leo] has designed the QAZ Personal Terminal to be about as small as a slabtop could be while still having full-sized keys.

Since the device is using a 35% QAZ keyboard as its primary input device, [Leo] has helpfully given a quick overview of how text is input in the video below. Coupled with that surprisingly popular 4:1 LCD screen we’ve seen elsewhere, this cyberdeck looks like a modern interpretation of a TRS-80 Model 100. The Banana Pi powering the QAZ Personal Terminal is running Debian with spectrwm, a tiling window manager making arranging windows a breeze with either a mouse or keyboard. The integrated mouse layer on the keyboard means you don’t need a separate mouse at all if you don’t want to spoil the 1980s mobile chic.

[Leo] has another video all about doing calculus on this cyberdeck with the math shortcuts integrated into the keyboard. Fractions, exponents, and common Greek letters are demonstrated. We can see this being a really great note-taking device for engineering and math courses if you wanted something more portable than a laptop.

It’s hard to get very far hacking without a little math. For more math-focused input devices, check out the Mathboard or the MCM/70.

2022 Cyberdeck Contest: Keezyboost40 Is A Cyberdeck Masquerading As A Keyboard

There’s something to be said for über-powerful cyberdecks, but there’s also a certain appeal to less powerful decks squeezed into a tiny form factor. [Christian Lo] has designed a cyberdeck that looks like a simple ortholinear keyboard but is running a more flexible environment.

There are games and animations you can play on QMK, but [Lo] felt that a different framework would give him more flexibility to really stretch the limits of what this Raspberry Pi Pico-powered deck could do. He decided to go with a Rust-based firmware with the keyberon library and says, “it felt like I was in control of the firmware.” While the board is using Rust for now, [Lo] says he’s open to conversations about other firmware options to achieve his goals, like a virtual pet game for the board.

The PCB is described as “bog standard” with the possible exception of placing the Pi in a cutout on the board to keep things as low profile as possible. The trade-off comes in the form of reduced board rigidity and potentially increased strain on the connections to the microcontroller.

Hackaday Prize 2022: A Not-So-Smart Spot Welder

October 17, 2022 by Navarre Bartz 5 Comments

DIY spot welders often use high-powered components that can be a bit frightening, given the potential for dangerous malfunctions. [Wojciech “Adalbert” J.] designed his capacitive discharge spot welder to be safe, easy to build, and forego the microcontroller.

Many projects work great with just a single Li-ion cell, but when you need more power, you’ve got to start connecting more cells together into a battery. [Wojciech]’s spot welder is designed to be just powerful enough to weld nickel tabs onto a cell without any overkill. The capacitor bank uses nineteen Nichicon UBY 7500uF/35V capacitors, all wired in parallel using solder wick saturated with solder. They sit atop on a perfboard with metallicized holes to carry the high current.

[Wojciech] has detailed every step of building the welder, including changes to the off-the-shelf relay board and adding a potentiometer to the step-up converter board. The level of detail makes this seem like a good starting place if you’re hoping to hop into the world of DIY spot welders. Safe is always a relative term when dealing with high powered devices, so be careful if you do attempt this build!

DIY spot welders have graced these digital pages many times, including this one built with safety in mind, and this other one that was decidedly not.

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.

An acrylic map of the state of Lagos. Each region is lit a different color by LEDs shining on the acrylic panels. The colors coorespond to the air quality index key which is lit in cooresponding colors to the value.

Hackaday Prize 2022: This Interactive Air Quality Map Makes The Invisible Visible

Air quality can have a big impact on your health, but it isn’t always something you can see. [Ahmed Oyenuga] wanted to make air quality something more tangible and developed an Interactive Air Quality Map.

Using addressable LEDs and acrylic panels, [Oyenuga]’s map lights up different regions of his state (Lagos) with colors that correspond to qualitative values of the air quality readings. The color key on the edge of the map becomes a readout when you touch a specific region of the map.

Most of the map’s functionality is handled by an Arduino WiFi 1010, but the capacitive touch is running on a custom board [Oyenuga] designed with an ATSAMD21J17. [Oyenuga] is getting air quality data via a DesignSpark Environmental Sensor Development Kit (ESDK) and then uses reverse geocoding to take the GPS data and turn it into a location the map will understand.

If you’re interested in different options for monitoring air quality that could feed into a map like this, why don’t you check out this LoRa Air Quality Monitor or even a Mobile Air Quality Monitor.
