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.

Keebin’ With Kristina: The One With The Chinese Typewriter

June 21, 2021 by Kristina Panos 12 Comments

As much as I’d like to devote an article to each and every bit of keyboard-related what-have-you that I come across in my travels through the intertubes, there just aren’t enough hours. And after all, this isn’t Clack-a-Day. To that end, I gained editorial approval to bring you a periodic round-up of news and other tidbits on the keyboard and keyboard accessories front, and here we are. So let’s get to it!

Go Ape With A Banana Macropad

May 14, 2021 by Kristina Panos 14 Comments

The super fun thing about macro pads is that they’re inherently ultra-personalized, so why not have fun with them? This appealing little keeb may have been a joke originally, but [dapperrogue] makes a valid point among a bunch of banana-related puns on the project page — the shape makes it quite the ergonomic little input device.

Inside this open-source banana is that perennial favorite for macro pads, the Arduino Pro Micro, and eight switches that are wired up directly to input pins. We’re not sure what flavor of Cherry those switches are, hopefully brown or green, but we suddenly wish Cherry made yellow switches. If you want to build your own, the STLs and code are available, and we know for a fact that other switch purveyors do in fact make yellow-stemmed switches.

Contrary to what the BOM says, we believe the sticker is mandatory because it just makes the build — we imagine there would be fewer double takes without it. Hopefully this fosters future fun keyboard builds from the community, and we can’t wait to sink our teeth into the split version!

There are a bunch of ways to make a macropad, including printing everything but the microcontroller.

This Pineapple Keyboard Is The Bomb

April 18, 2021 by Kristina Panos 29 Comments

Now why didn’t we think of this? While building a dactyl manuform — a semi-ergonomic split keyboard — [dapperrogue] had the life-changing epiphany that keyboards can be any shape or size, as long as there is room for wiring and a microcontroller inside. [dapperrogue]’s first foray into the world of fictional ordnance came in the form of an F-bomb — a round macro keeb made in the classic round explosive shape and covered with function keys. Building on the explosive feedback from that, [dapperrogue] built this bomb of a pineapple keeb, the only anti-personnel factor being the clickiness of the key switches.

This groovy grenade has 25 keys total, 24 of which are in a 4×6 grid around the body. The 25th key, the best one, is hiding under the lever and you bet it can only be actuated by pulling the pin first. We love the use of the lever because it makes us think of Morse code keyers, which might be what we would use that switch for.

Inside is an Arduino Pro Micro running QMK and some skillful wiring. The entirely 3D-printed enclosure is in two main pieces that are connected with M3 screws, plus the top. If you want to pack one of your own, the STLs and firmware are out on GitHub. Just don’t take it to the airport.

Be sure to check out the demos after the break — in the stock firmware, every key types out a different onomatopoeic boom-type sound. Are you more of a pacifist when it comes to macro pad design? That’s understandable. We have plenty of different builds to admire.

3D-Printed Macro Pad Ditches The PCB With Slick Wiring Guides

March 2, 2021 by Donald Papp 15 Comments

Reddit user [duzitbetter] showed off their design for a 3D-printed programmable macro keyboard that offers a different take on what can be thought of as a sort of 3D-printed PCB. The design is called the Bloko 9 and uses the Raspberry Pi PICO and some Cherry MX-style switches, which are popular in DIY keyboards.

The enclosure and keycaps are all 3D printed, and what’s interesting is the way that the enclosure both holds the components in place as well as providing a kind of wire guide for all the electrical connections. The result is such that bare copper wire can be routed and soldered between leads in a layout that closely resembles the way a PCB would be routed. The pictures say it all, so take a look.

Bloko 9 is available as a paid model, and while going PCB-free thanks to 3D printing is a technique others have played with, it is very well demonstrated here and shows there is still plenty of room to innovate on the concept. DIY keyboard and macro pad design is also fertile ground for hackers; we have even seen that it’s possible to 3D print one right down to the switches themselves.

Micro Macro Keyboard Is ‘Mega-Based

November 19, 2020 by Kristina Panos 3 Comments

There’s a certain kind of joy that comes in throwing something together from spare parts, or from finding utility in a proof of concept for another project. [Clewsy] is cooking up something clacky and built this baby keeb to prove some stuff out, such as reading a key matrix. Now it’s become a music/media controller that looks great next to a giant matching volume knob.

Beneath the gently backlit Gateron blues is a custom ATMega32u4-based board, which is viewable through the clear acrylic bottom plate. That’s a nice touch. We’re not sure if the wood came from a picture frame, but if not, they seem like a great candidates for enclosure material.

This keeb looks fantastic, and we are partial to both the clear and the chrome keycaps. We can only hope [Clewsy] sends the details of the next build our way.

If you want to get started building keyboards, you can’t go wrong with a macro keyboard like this one. If you have way more than four macros in mind, build something bigger, like a custom game pad with a joystick.

DIY Ergonomic Game Pad Lends A Hand

September 23, 2020 by Kristina Panos 8 Comments

Does it seem like everyone you game against can do everything faster than you? Chances are good that they have some kind of dedicated game pad or macro pad with a bunch of custom shortcuts. If you can’t beat ’em, join ’em, but why buy one when you can build your own? [lordofthedum] did the smart thing when they built their own version of the Azeron game pad, which is an outrageously expensive but ergonomic and cool-looking macro pad that reminds us of the DataHand ergonomic keyboard.

Each finger hovers over a C-shaped group of three switches — one actuates by moving the finger forward, another by moving backward, and the third by pushing down like a regular button. The thumb gets a 4-way joystick. All of these inputs are wired up to an Arduino Pro Micro, which has sort of become the standard for DIY macro pads and keyboards. We think this looks fantastic, and really raises the bar for DIY macro pads.

Need a few more keys, but still want a thumb joystick? Check out the smooth and sweet Sherbet game pad.
