Inside the making of a cylindrical keyboard that doubles as a tea cup.

Can’t Spill Coffee On Your Keyboard If It’s Already Inside

October 11, 2021 by Kristina Panos 7 Comments

No matter where you live in the world or what beverage you enjoy, it’s too easy to spill it on the keyboard. Obviously, the solution is to combine the two. That’s exactly what Google Japan did this past April Fool’s Day when they released the Gboard — a cylindrical keyboard wrapped around a removable cup. But is it still a joke once you’ve open-sourced it and made a build guide, more or less?

Here’s where it gets weird: each kanji on the keyboard represents a different kind of fish, and they’re laid out in Japanese phonetic order. You’re not stuck with the fish, though — one of the 60 keys switches between fish input and regular Hiragana (the basic Japanese phonetic alphabet). Underneath all those fish are low-profile Kailh chocs hooked up to an ATMega32u4. We only wish it were wireless.

We love that they open-sourced this keyboard, and it even makes sense in a way. In order to produce a good April Fool’s video, you actually have to make the fake product. The better it is (i.e. weird but plausible), the more people will like it and probably want one. So if you’re going to go to all that trouble, why not set it free on GitHub? Note that the second line of the readme is “this is not an officially-supported Google product”, which we suppose goes without saying.

Be sure to check out the short video after the break. If you don’t understand Japanese, you’ll want to turn on the closed captions.

You know, now that Raspberry Pi have made their answer to the Arduino, it’s about time that Apple made their answer to the Raspberry Pi.

Home Automation Terminal With Cyberpunk Style

September 22, 2021 by Tom Nardi 3 Comments

The OLKB-Terminal designed by [Jeff Eberl] doesn’t have a battery, can’t fold up (even if it seems like it could), and is only portable in the sense that you can literally pick it up and move it somewhere else. So arguably it’s not really a cyberdeck per se, but it certainly does look the part. If you need to be furiously typing out lines of code in a dimly lit near-future hacker’s den, this should do you nicely.

[Jeff] has provided everything you’d need to recreate this slick little machine on your own, though he does warn that some of the hardware decisions were based simply on what he had on-hand at the time, and that better or cheaper options may exist. So for example if you don’t want to use the Raspberry Pi 4, you can easily swap it out for some other single-board computer. Though if you want to change something better integrated, like the LCD panel, it will probably require modifications to the 3D printed components.

The rear electronics tray offers plenty of room for expansion.

The slim mechanical keyboard that [Jeff] used for the OLKB-Terminal, which in some ways set the tone for the whole design, is actually a completely separate open source project from [Victor Lucachi]. The VOID30 is a 3D printed, 30% handwired ortholinear keyboard that runs the popular QMK firmware on an Arduino Pro Micro. He’s implemented a couple tweaks, namely using a USB-C equipped Arduino clone, but otherwise it’s the same as upstream. So if you’re not in the market for a little bedside cyberpunk terminal but love its sleek keyboard, you’re in luck.

Software wise, [Jeff] has the OLKB-Terminal hooked into his larger Home Assistant system. This gives him an attractive status display of the whole network, and with just a tap on the terminal’s seven inch touch screen, he’s able to directly control devices around the home. That said, at the end of the day it’s just a Raspberry Pi, so it could really run whatever you want.

While cyberdeck builds might be all the rage right now, we do appreciate projects that bring those same design tenets to the desktop. From the gorgeous faux-retro designs of [Oriol Ferrer Mesià] to modernized pieces of vintage hardware, truly personal computers that can be easily upgraded and repaired don’t have to be limited to something you can lug around with a guitar strap.

Kinesis + Teensy = QMK Advantage Over Your Keyboard

August 5, 2021 by Kristina Panos 11 Comments

Back in 2013, [Michael Stapelberg] created what is lovingly referred to as the Stapelberg controller: a replacement keyboard controller for the original Kinesis Advantage, the decades-old darling of the ergonomic clacking world. Whether you’re building a new keeb, you’ve got a broken Kinesis, or you simply want to run QMK on the thing and don’t mind getting your hands dirty, there’s a new Stapelberg controller on the block. It’s called the kinT, for Kinesis + Teensy.

[Michael] built kinT in response to the Advantage 2, which came along in 2017 and changed the way the thumb clusters connect to the main board from a soldered cable to an FPC connector. Whereas the original Stapelberg controller was built in Eagle, this one was done in KiCad and is open-source, along with the firmware. You can use a Teensy 4 with this board but if you don’t have one, don’t worry — kinT is backwards-compatible with pretty much every Teensy, and it will even work on the original Advantage.

Are you on the fence about going full ergo? Check out my in-depth review of the original Kinesis Advantage I got that’s almost 20 years old and still clacking along like new. But don’t wait for a repetitive stress injury to go full ergo. Trust me.

Hands On: DEF CON 29 Badge Embraces The New Normal

August 5, 2021 by Tom Nardi 13 Comments

To say that 2020 was a transformative year would be something of an understatement. The COVID-19 pandemic completely changed the way we worked, learned, and lived. Despite all those jokes about how much time people spend on their devices rather than interacting face-to-face with other humans, it turns out that when you can’t get more than a few people together in the same room, it throws our entire society into disarray.

Our community had to rethink how we congregated, and major events like HOPE, DEF CON, and even our own Hackaday Supercon, had to be quickly converted into virtual events that tried with varying degrees of success to capture the experience of hundreds or thousands of hackers meeting up in real life. While few would argue that a virtual hacker convention can ever truly replace a physical one, we learned there are undeniable benefits to embracing the advantages offered by cyberspace. If nothing else, the virtual hacker meetups of 2020 saw a far larger and more diverse array of attendees and presenters than ever before.

As we begin seeing the first rays of light at the end of the long, dark, tunnel we’ve been stuck in, it’s clear that some of the changes that COVID-19 forced on our community are here to stay. As eager as we all are to get back to the epic hackfests of old, nobody wants to close the door on all those who would be unable to attend physically now that they’ve gotten to peek behind the curtain.

With this in mind, this year’s DEF CON is being presented in both physical and virtual forms simultaneously. If you made to Las Vegas, great. If not, you can follow along through chat rooms and video streams from the comfort of your own home. Following the theme, the DC29 badge is not only a practical tool for virtual attendees, but an electronic puzzle for those who are able to bring a few of them together physically. Let’s take a closer look at this socially distanced badge and the tech that went into it.

Printable Hot-Swap Sockets Make Keyboard Building Even Cooler

June 16, 2021 by Kristina Panos 7 Comments

Okay, so you want to build a keyboard — something crazy-curvy like the dactyl or dactyl manuform. The kind of keyboard that has to be hand-wired, because key wells and rigid PCBs do not play well together. You want to build this keyboard, but all that hand-wiring would mean that you can’t easily swap switches later. And it will means hours and hours of fiddly soldering. What do you do? You could buy or design your own switch PCBs, but again, those are rigid and space is limited inside of most of these designs.

If you’re [stingray127], you trade those hours of soldering for a week of designing and printing some sweet little hot-swap sockets with wire guides. This is version four, which is easier to print than earlier versions. They are designed to use through-hole diodes and 24 AWG solid-core wire and give a tight fit. Can’t figure out how to use them? [stingray127] has a wiring guide with plenty of pictures.

We really like this idea, and it makes the end result feel more like a totally hand-wired keyboard than individual switch PCBs would As you can see, it involves little solder. The only downside is that you can only swap a few switches at a time, otherwise the matrix might fall apart. But that’s hardly even a downside.

Just want to make a macropad? You can easily print your way out of using a PCB for those, too.

Spherical Keyboard Build Leaves Hacker Well-Rounded

May 20, 2021 by Kristina Panos 20 Comments

Often times we as hackers don’t know what we’re doing, and we sally forth and do it anyway. Here at Hackaday, we think that’s one of the best ways to go about a new project, and the absolute fastest way to learn a whole lot as you go. Just ask [Aaron Rasmussen] regarding this spherical, standing 5×6 dactyl manuform keyboard build, which you can see in a three-part short video series embedded after the break.

[Aaron] gets right down to it in the first video. He had to get creative right away, slicing up the dactyl manuform model to fit on a tiny print bed. However, there’s plenty of room inside the sphere for all that wiring and a pair of Elite-C microcontrollers running QMK. Be sure to turn on the sound to hear the accompanying voice-overs.

The second video answers our burning question: how exactly does one angle grind a slippery sphere without sacrificing sheen or shine? We love the solution, which involves swaddling the thing in duct tape and foam.

You may be wondering how [Aaron] is gonna use any kind of mouse while standing there at the pedestal keyboard. While there is space for a mouse to balance on top, this question is answered in the third video, where [Aaron] learns the truth behind the iconic ThinkPad nubbin and applies this knowledge to build a force-feedback joystick/trackpoint mouse. Awesome answer, [Aaron]!

Not ready to go full-tilt, sci-fi prop ergo? Dip your toe in the DIY waters with a handy macropad.

Heavy Metal Cyberdeck Has An Eye Towards Expansion

April 15, 2021 by Tom Nardi 17 Comments

Whether we’re talking about Gibson’s Sprawl or our increasingly dystopian reality, one of the defining characteristics of a cyberdeck is that it can be easily customized and upgraded over time. While a few of the builds we’ve covered over the last couple of years have focused more on style than substance, we really appreciate the designs that embrace the concept of modularity to make sure the system can evolve to meet the changing demands of hacking on the go.

To that end, the M3TAL from [BlastoSupreme] is a perfect example of what a cyberdeck should be. Naturally it’s got the cyberpunk aesthetics we’ve come to expect, but more importantly, it’s designed so modifications and repairs are as quick and painless as possible. The trick is the use of a 2020 aluminum extrusion frame, which allows external panels and components to be attached anywhere along the length of the deck using T-Nuts. Similarly, by mounting internal components to “sleds” that ride between the pieces of extrusion, the electronics can easily be removed or swapped out as complete modules.

The M3TAL is currently outfitted with a Raspberry Pi 4 and a pair of 26650 batteries.

Furthering the idea of expandability, [BlastoSupreme] included an authentic 3.5 floppy drive on the M3TAL that allows him to pack an incredible 1.44 MB onto each rugged and portable disk. OK, so maybe the floppy drive isn’t terribly impressive compared to 2021 tech, but it does seem oddly appropriate for a cyberdeck. On the opposite side of the deck there’s a RetroCART slot, which cloaks modern USB devices in clunky faux cartridges. This provides a unified physical format for everything from removable storage to microcontrollers and software defined radio receivers.
