All The Hardware Badges Of DEF CON 25

Hardware is the future. There is no better proof of this than the hardware clans that have grown up around DEF CON, which in recent years has become known as Badgelife. I was first drawn to the custom hardware badges of the Whiskey Pirates at DC22 back in 2014. Hardware badges were being made by several groups at that time but that was mainly happening in isolation while this year the badge makers are in constant contact with each other.

A slack channel just for those working on their own DEF CON badges sprung up. This served as tech support, social hour, and feature brainstorming for all on the channel. In the past badges were developed without much info getting out during the design process. This year, there was a huge leap forward thanks to a unified badgelife API: the badge makers colluded with each on a unified communcations protocol. In the multitude of images below you frequently see Rigado modules used. These, and some others using different hardware, adopted a unified API for command and control, both through makers’ “god mode” badges, and for wireless gaming between participant badges.

I was able to get into the badge makers meetup on Thursday of DEF CON. What follows is the result of a frantic few hours trying to get through the sheer volume of badges and people to share with you all the custom hardware on display. One thing is for sure — there were literally thousands of custom badges built and sold/distributed during DEF CON. I can’t wait to see what the artisanal hardware industry will look like in five years time.

Building A DEF CON Badge In Two Weeks

DEF CON is starting right now, and this is the year of #badgelife. For the last few years, independent hardware wizards have been creating and selling their own unofficial badges at DEF CON, but this year it’s off the charts. We’ve already taken a look at Bender Badges, BSD Puffer Fish, and the worst idea for a conference badge ever, and this is only scratching the surface.

This is also a banner year for the Hackaday / Tindie / Supplyframe family at DEF CON. We’re on the lookout for hardware. We’re sponsoring the IoT village, [Jasmine] — the high priestess of Tindie — and I will be spending some time in the Hardware Hacking Village, praising our overlords and saying the phrase, ‘like Etsy, but for electronics’ far too much. We’ll be showing people how to solder, fixing badges, and generally being helpful to the vast unwashed masses.

Obviously, this means we need our own unofficial DEF CON badge. We realized this on July 10th. That gave us barely more than two weeks to come up with an idea for a badge, design one, order all the parts, wait on a PCB order, and finally kit all the badges before lugging them out to DEF CON. Is this even possible? Surprisingly, yes. It’s almost easy, and there are zero excuses for anyone not to develop their own hardware badge for next year’s con.

DEF CON Badgelife: The ESP Rules All

Badgelife is the celebration of independent hardware creators, working for months at a time to bring custom electronic badges to conferences around the world. This year at DEF CON, Badgelife is huge. It’s not just because this year was supposed to feature a non-electronic badge, and it’s not because the official badge imploded last month — Badgelife is all about people spending most of the year designing, and manufacturing hardware, culminating in one very special weekend.

[Garrett] owns Hacker Warehouse, a store providing all kinds of neat hacker tools ranging from software-defined radios to lock pick sets to side channel analysis toolkits. This year, [Garrett] decided he wanted to branch out his business and get involved in a little bit of hardware creation. He’s been curious about this for some time and figured a limited edition DEF CON badge made sense. What he wound up with is a beautiful little badge with games, blinkies, graphics, and potential to cause a lot of wireless mischief.

Would you look at that. RF design on an independent badge.

The design of the Hacker Warehouse badge is surprisingly simple compared to the Bender Badges and puzzling crypto badges that are also part of this year’s Badgelife hardware celebration. On board is an ESP8266 with a custom PCB implementation that includes a larger Flash chip. The other side of the board is loaded up with four tact switches in a D-pad arrangement. On top is a 96 x 64 pixel full-color OLED display, and blinkies are provided by fourteen mini WS2812 RGB LEDs. Power is provided by two AA cells and what looks to be a nice fancy switching regulator. This is real hardware, not just a few modules thrown together with a bunch of LEDs.

Oh, what wireless fun

This badge is built around the ESP8266, a very interesting WiFi-enabled microcontroller that has more features than it should. [Garrett] is using the ESP as a WiFi scanner of sorts, allowing anyone with this badge to monitor WiFi channels, APs, packets, and — this is important — deauth packets.

Over the last year, there have been a number of projects around the Internet that take an ESP8266 and spew deauthorization frames into the spectrum. These frames cause a WiFi client to stop using an access point, and basically shuts down all the WiFi in an area. It’s well documented, and people have been doing it for years, but the ESP8266 makes deauth attacks so very, very easy. We’re going to see a lot of deauth frames this year at DEF CON, and the Hacker Warehouse badge will be able to detect them. It can also generate these frames, but that capability is locked for now.

Blinking and glowing

An electronic conference badge isn’t cool unless it has obnoxiously bright and glowy LEDs, and the Hacker Warehouse badge is very cool.

Onboard the Hacker Warehouse badge are 14 RGB LEDs, programmed with 46 different patterns that are certainly bright enough to annoy someone. This is what you need for a badge, and it’s beautiful.

This is a truly fantastic badge that’s also a great development board for the ESP8266. Everything you need for portable WiFi gaming fun is already there — you have blinky LEDs, an OLED, what seems to be a fairly nice power supply, and enough buttons to do something interesting. All you need to do to program this badge is attach a USB to serial adapter to the pre-populated header and you really have something. It’s a great badge, and we can’t wait to see the hacks for this great piece of hardware next week at DEF CON.

DEF CON Badgelife: Someone Finally Did It

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.

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

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

Friday Hack Chat: BadgeLife

For the last few years at DEF CON, we’ve seen the emergence of an entire community of badge creators. These aren’t official badges — good news, since the official DEF CON badge will probably be an unpuzzling piece of laser cut acrylic this year. Lucky for us this is the biggest year yet for independent electronic badges. This is BadgeLife, the fine art of designing and building hundreds of badges for eager conference goers.

This Friday, we’ll be hosting a Hack Chat with a few of the folks tapped into BadgeLife. [Whitney Merrill], lawyer, hacker, and overseer of the Crypto & Privacy village will be joining us talking about this year’s badge, the puzzle she designed, and what BadgeLife really means. Also joining us will be [Karl Koscher], research scientist and co-organizer of the Crypto and Privacy village.

Also on deck will be the creators of this year’s Bender Badge. Last year, AND!XOR created one of the most popular electronic conference badges in recent memory. This year, the Bender Badge is getting an upgrade with Blast Processing, a quart of tequila, and two dozen amyls.

We’re proud to note that Hackaday.io has become an unofficial repository for all the best badges from the BadgeLife community. The Hunter S. Rodriguez badge is on there, as is the Ides of DEF CON. As the creator of the most innovative and desirable badge this year, I will also be attending this Hack Chat discussing the trials and tribulations of developing and shipping hardware on a very condensed schedule.

While the focus of this BadgeLife Hack Chat is developing electronic conference badges for DEF CON, it could have easily been called ‘Electronic Design’. There’s a massive amount of work that goes into each of these badges from design to production, and all of it is highly relevant to any hardware developer.

Here’s How To Take Part:

DEF CON BadgeLife: Blinky Bling

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.
