DEF CON Badgelife: Someone Finally Did It

July 18, 2017 by Brian Benchoff 11 Comments

Badgelife is the celebration of electronic conference badges, a way of life that involves spending far too much time handling the logistics of electronics manufacturing, and an awesome hashtag on Twitter. Badgelife isn’t a new thing; it’s been around for a few years, but every summer we see a massive uptick in the lead up to Def Con.

For the last few years, the designers and engineers deep into Badgelife have had the same conversation dozens of times. One person says, “you know, someone should build a badge that’s a quadcopter.” Another person replies, “Can you imagine how annoying that would be? You’d be putting ten thousand people in a room during the closing ceremonies at DefCon, and a few dozen people would have quadcopters. It would be horrible” Yes, there have been plans to build a quadcopter badge for the last few years, but cooler heads prevailed.

Someone finally did it. The wearable electronic conference badge that’s also a quadcopter is finally here. It’s the work of [b1un7], and it’s going to be exactly as annoying as you would expect.

The controller for the badge quad.

This badge is actually two PCBs, the first being the quadcopter itself, the second being the joystick/controller. The quad is shaped like the familiar jolly roger found in most Whiskey Pirate badges ([b1un7] hangs with that crew), and the controller is a pirate’s treasure map loaded up with joysticks, buttons, and radios. The motors for this quad appear to be brushed, not brushless, and it looks like the arms of the quad have some space for obnoxiously bright LEDs.

This is an awesome badge but it’s still [b1un7]’s first attempt at making a badge. Right now, there’s still a bit of work to do — there’s only one week until Defcon — but with any luck [b1un7] will have 25 of these wearable electronic conference badges buzzing around. It’s a terrible idea and we love it.

Badge From Diamond Age Comes To DEF CON

July 14, 2017 by Mike Szczys 12 Comments

We’re huge fans of [Neal Stephenson’s] work and are usually looking to assign some of his vision to the gear that pops up in the real world. But there’s no stretching or squinting necessary with this one. [Kerry Scharfglass] has built a functioning Drummer’s Badge from the foundational Sci-Fi novel The Diamond Age.

The badge is called Sympetrum, which is a genus of dragonfly. In explaining what the badge is and does, [Kerry] instructs you to go and read the book first and we couldn’t agree more. This isn’t recommended reading; if you’re a geek you need to read this book.

The dragonfly badges are from a portion of the book that gets pretty weird, but the gist is that rod-logic (machines build from microscopic carbon nanotubes) is so pervasive that at all times you’re covered in mites that are actually machines. At a party, one of the characters notices everyone is wearing dragonfly pins that begin to pulse with the music and synchronize with each other. They’re actually indicators of what the mites within the wearers’ bodies are doing — synchronizing people with other people.

This badge is a working recreation of that, presumably without the billions of mites controlling people (but who knows, it is DEF CON). At the center of the badge is an STM32 driving ten APA102 modules. Interactivity is based on IR signaling. The badge will cycle random color animations when alone. But each badge also projects clock sync and metadata over infrared, so put some of them in the same room and they’ll tend to synchronize.

Simple, beautiful, and a great geeky backstory. This example of Badgelife proves that hardware badges don’t need to be packed with features, or have a huge BOM cost. If done well, you can do an awful lot with just a little hardware and strong dose of inspiration. It also makes hand-assembly a lot more approachable, which is what you can see in the images above. Thanks [Kerry] for giving us an early look at this badge, can’t wait to see them at the CON.

We’ll be looking for this and all other #Badgelife offerings at DEF CON 25. Join us for a Hackaday meetup on Sunday morning as we once again do Breakfast at DEF CON

Hands-On: New AND!XOR Unofficial DEF CON Badge

July 12, 2017 by Mike Szczys 11 Comments

In just two weeks, we’ll be flooding into the casinos of Las Vegas for DEF CON. By far our favorite part is the unofficial hardware badges which make their way to the con each year. The AND!XOR team has put together an incredible offering this year with what I’m calling the “Bender on a Bender” badge. They sent us two of them, so let’s jump right in and see what this badge is all about.

DEF CON BadgeLife: Blinky Bling

July 10, 2017 by Brian Benchoff 6 Comments

This is the biggest year yet for unofficial electronic conference badges. We’re calling it the year of Badgelife, and for the next few weeks, we’re going to be taking a look at the unofficial conference badges being deployed at this year’s DEF CON.

[Mr Blinky Bling] a.k.a. [Benn Hibben] has created his own badge for this year’s con. On board is a bunch of LEDs, WiFi, and capacitive buttons. It’s a WiFi badge for all your AP scanning and deauth needs. The electronics for this badge are a bit more complicated than simply throwing an ESP8266 on a board and calling the design done. The capacitive touch functionality is being handled by an ATTiny88, the OLED display is handled by an ATMega32U4, wireless functions are done with an ESP8266, and there are a few bits and bobs for a LiPo battery.

This WiFi Badge is the focus of an astonishingly successful Kickstarter (ending in just a few hours), and [Mr Blinky Badge] already has enough backers to move 200 badges. This is really a spectacular amount of work; it’s one thing to build a single prototype for an electronic conference badge, but it’s another matter entirely to put a badge into production, source all the parts, handle the assembly, and finally ship all these badges to Kickstarter backers and conference attendees.

If the challenge of building and deploying hundreds of electronic conference badges sounds like fun, you’re in luck. This Friday, we’ll be hosting a Hack Chat with some of the creators of this year’s unofficial DEF CON badge creators. There’s a lot you can learn from these folks, and a lot of very cool badges that will make an appearance at this year’s Def Con.

DEF CON Badgelife: The Puffy That Runs Linux

July 7, 2017 by Brian Benchoff 9 Comments

DEF CON is canceled again this year, and this time that statement is at least partially true. There will be no special official badges this year. There is no challenge or mystery embedded in the official DC badge. This is the year that unofficial badges from villages and random attendees finally supersedes the official offering. This is badgelife, and for the next few weeks, we’re going to be taking a look at some of the unofficial badges of DEF CON.

The idea for [dorkengine]’s Puffy badge began last year with the so-called Bender badges from AND!XOR. Chalk this up to a story that ends with, ‘but you had to have been there’, but the Bender badges were wildly popular, sold like hotcakes, and were an astonishing success of independent badge craft at DC. [dorkengine] decided to get in on the action and build his own badge for DC 25.

The design of the Puffy badges is based on a highly stylized rendering of the OpenBSD logo and mascot. Why a pufferfish with Kardashian lips? [dorkengine] has a bunch of boxes in a closet running OpenBSD, and that’s a good enough reason for us.

An electronic badge must do something, and the feature list [dorkengine] came up with included some sort of wireless connectivity, hackability, a serial console, blinkenlights, and some sort of *nix-ish OS. OpenBSD didn’t make the cut, but [dorkengine] eventually stumbled upon the VoCore2, a tiny System on Module that runs Linux, has WiFi and a few GPIOs, and is barely an inch on a side.

After getting a good deal on a large order of VoCores, [dorkengine] started on the PCB. The circuit was simple enough with just a VoCore attached to a USB port, power adapter, and a few LEDs. The Puffy rendering translated beautifully into soldermask and silkscreen, and after a prototype from ITEAD Studio, [dorkengine] had 40 PCBs that worked perfectly.

So, what is [dorkengine] going to do with a box full of Puffy badges? He’ll be selling them for $40 around the con. That’s surprisingly inexpensive for a large PCB soldered to a $17 SoC. If you want to get your grubby mitts on one, you could email him or ping him on Twitter. Of course, if you want to make your own, [dorkengine] has the KiCad files and software available, but at this point, you’re looking at a very fast turnaround for a board house.

Hardware Tribes Growing Up Around Artisanal Electronics

March 15, 2017 by Mike Szczys 10 Comments

Consumer electronics are design beasts that must serve many masters. There’s a price point for the product itself, a ceiling for the feature set (lest it not be ‘user friendly’), and to take the risk of actually manufacturing something there needs to be proof of the market. A lot of great things make it through this process, but some really unique and special gear goes completely around it.

So is the story of this AND!XOR hardware badge being built for DEF CON 25. This is not the official conference badge, but the latest in a growing trend of hardware/firmware engineers and hackers who design their own custom gear for the conference, trying to one-up not just the official badge, but the other hardware tribes doing the same. This unique hardware excitement is a big reason that Hackaday has developed electronic badges for our conferences.

The new badge is a mashup of Bender from Futurama and Raoul Duke from Fear and Loathing in Las Vegas, presents something of monstrosity to hang around your neck. That has certainly never stopped us from having one of these bouncing around our necks as we pound the cattle paths from talk to talk (and the DC23 vinyl record was way more unwieldy anyway).

Bender’s forehead display has now been upgraded from a diminutive OLED to a generous color LCD display. The 433 MHz which used the spring antenna on the previous badge has given way to a Bluetooth Low Energy. The BLE is built into the Rigado BMD-300 SOC that is now in conrol of the badge. We can’t wait to see the shenanigans unlocked with this new hardware — they’re already showing of crazy animations, retro gaming, and teasing a huge multiplayer game with all the badges. Finally, the “Secret Component” at the bottom of their components list delivers the je ne sais quoi to the whole project.

Fans of AND!XOR have already thrown their weight behind it. Unofficial badges have been unavailable to a wider group or only offered in flash-sales that pop up during the con. Last year the team was met with a huge mob throwing money at their supply of 175 badges. Now the AND!XOR team has grown to five people toiling away to make the design, the easter-egg laden firmware, and the manufacturing process better than the amazing work of last year. They just launched a crowd funding campaign on Tuesday and immediately blew past their goal about five times over.

We’re hoping to get our mitts on one of these ahead of DEF CON to give you an early look at what these hardware artists have accomplished. If you’re part of another hardware tribe building custom electronics for the love of it, we’d really like to hear from you. This goes for any conference — we know of at least one other in progress.
