[Bunnie] was at Burning Man this year, and to illuminate his camp members in the dark and dusty nights of the playa, he created a blinky badge. This isn’t just any badge stuffed with RGB LEDs; each of the badges were unique by the end of Burning Man. These badges were made unique not by twiddling dials or pressing buttons; all the color patterns were bred with badge sex.
This social experiment to replicate nature’s most popular means of creating more nature is built around a peer to peer radio. Each badge is equipped with a radio, a circle of RGB LEDs, and a bit of code that expresses the pattern of lights on the badge as a sequence of genes. When one badge gives consent to another badge, they ‘breed’, creating a new pattern of lights. If you’re wondering about the specifics of the act, each badge is a hermaphrodite, and each badge transmits a ‘sperm’ to fertilize the other plant’s ‘egg’. There’s even a rare trait included in the genome of the badge; each badge has a 3% chance of having a white pixel that moves around the circle of LEDs. [Bunnie] found this trait was more common after a few days, suggesting that people were selectively breeding their badges.
Of course, finding potential mates is a paramount concern for any sexual organism, and the sex badge has this covered, too. The 900MHz radio listens for other badges in close proximity, and when any are found their owners are displayed on an OLED display. This came in handy for [Bunnie] more than a few times – there’s no phones out there, and simply knowing your friends are within a hundred meters or so is a big help.
The entire badge platform is documented online, along with the code and spec for badge genes. Badges with some sort of wireless communication have been around for a while, but this is the first time that communication has been used for something more than sharing contact information or implementing a chat room. It’s a great idea, and something we hope to see more of in future con badges.
Last week, Parallax released an open hackable electronic badge that will eventually be used at dozens of conferences. It’s a great idea that allows badge hacks developed during one conference to be used at a later conference.
[Mark] was at the Hackable Electronics Badge premier at the 2015 Open Hardware Summit last weekend, and he just finished up the first interactive hack for this badge. It’s the zombie apocalypse in badge form, pitting humans and zombies against each other at your next con.
The zombie survival game works with the IR transmitter and receiver on the badge normally used to exchange contact information. Upon receiving the badge, the user chooses to be either a zombie or survivor. Pressing the resistive buttons attacks, heals, or infects others over IR. The game is your standard zombie apocalypse affair: zombies infect survivors, survivors attack zombies and heal the infected, and the infected turn into zombies.
Yes, a zombie apocalypse is a simple game for a wearable with IR communications, but for the Hackable Electronics Badge, it’s a great development. There will eventually be tens of thousands of these badges floating around at cons, and having this game available on day-one of a conference will make for a lot of fun.
Electronic conference badges have been around for at least a decade now, and they all have the same faults. They’re really only meant to be used for a few days, conference organizers and attendees expect the badge to be cheap, and because of the nature of a conference badge, the code just works, and documentation is sparse. Surely there’s a better way.
Enter the Hackable Electronic Badge. Ever since Parallax started building electronic conference badges for DEF CON, they’ve gotten a lot of requests to build badges for other conventions. Producing tens of thousands of badges makes Parallax the go-to people for your conference badge needs, but the requests for badges are always constrained by schedules that are too short, price expectations that are too low, and volumes that are unknown.
There’s a market out there for electronic conference badges, and this is Parallax’s solution to a recurring problem. They’re building a badge for all conferences, and a platform that can be (relatively) easily modified while still retaining all its core functionality.

We’re going to build an electronic Hackaday Badge, and by “we”, I mean Hackaday community members who are passionate about the project.
I’ll be leading the charge. I had a great learning experience the last time I helped design the e-paper badge for the 2013 Open Hardware Summit, and hope to learn a lot along the way this time too. Since then, Badges have come a long way – at cons like DEFCON, LayerONE, Shmoocon, The Next Hope, Open Hardware Summit, The EMF, SAINTCON, SXSW Create, The Last Hope, TROOPERS11, ZaCon V and of course the rad1o from this year’s CCCamp. Word is that this year’s Open Hardware Summit badge is going to be pretty kickass too. So, we have some very big shoes to fill. But this doesn’t have to be about “my badge is better than yours”. And this badge isn’t meant to be specific to any single con or event. So what does the Badge do, then? “It’s a physical extension of the hackaday.io community, made specifically for hacker gatherings of all types and sizes.”

2015 was the year of the unofficial hardware badge at DEF CON 23. There were a ton of different hardware badges designed for the love of custom electronics and I tried to catch up with the designer of each different badge. Here is the collection of images, video demos, and build details for each one I saw this weekend.
Gorgeous text treatment on back of this badge is indicative of [True’s] mastery
[TrueControl] did a great job with his badge design this year for the Whiskey Pirate Crew. This is a great update from the badge he designed last year, keeping the skull and bones outline. It uses a PSOC4 chip to control a ton of LEDs. The eyes are RGB pixels which are each on their own PCB that is soldered onto the back of the badge, with openings for the LED to show through. Two AA batteries power the board which has a surface-mount LED matrix. The user controls are all capacitive touch. There is a spinner around one eye, and pads for select and back. The NRF24L01 radio operates at 2.4GHz. This badge is slave to commands from last year’s badge. When the two are in the same area the 2015 badges will scroll the nickname of the 2014 badge it “sees”. The piezo element also chirps many different sounds based on the interactions with different badges.
[True] makes design an art form. The matte black solder mask looks fantastic, and he took great care in use of font, size, alignment, and things like letting copper show through for a really stunning piece of hardware art.
Keep reading for ten more great badges seen over the weekend.

The 23rd DEFCON — the Western Hemisphere’s largest hacker conference — doesn’t start until tomorrow but Thursday has become the de facto start for regulars. [Brian] and I rolled into town this afternoon and are working on gathering as much information as possible about the badge challenge.
This year the badge is a 7″ vinyl record. Traditionally the badge alternates years of electronic badges and ones that aren’t. Spend your weekend pulling your hair our trying to solve the puzzles. Check out all the pictures and information (updated as we gather it) and work together collaboratively for a solution by requesting to join the crew on the Badge Hacking page.
Hackaday Breakfast on Sunday
If you’re in town Sunday morning, come nurse your hangover with [Brian], [Eric], and me. We’re headed to Va Bene Caffè at 10:30am on 8/9/15. It’s just across the street in the Cosmopolitan. Request to join this event and I’ll send you a reminder so you don’t forget. You can also hit me up on Twitter for a reminder. See you then (and don’t forget to bring hardware to show off if you have some!).
PS- The Hackaday WiFi Hat is in play. Anyone have the chops to hack it this year?
Conference badges are getting more complex each year. DEFCON, LayerONE, Shmoocon, The Next Hope, Open Hardware Summit, The EMF, SAINTCON, SXSW Create, The Last Hope, TROOPERS11, ZaCon V and of course the CCC, have all featured amazing badges over the years. This years CCCamp 2015 rad1o badge is taking things several notches higher. The event will run from 13th through 17th August, 2015.
The rad1o Badge contains a full-featured SDR (software defined radio) transceiver, operating in a frequency range of about 50 MHz – 4000 MHz, and is software compatible to the HackRF One open source SDR platform. The badge uses a Wimax transceiver which sends I/Q (in-phase/quardrature-phase) samples in the range of 2.3 to 2.7 GHz to an ARM Cortex M4 CPU. The CPU can process the data standalone for various applications such as FM radio, spectrogram display, RF controlled power outlets, etc., or pass the samples to a computer using USB 2.0 where further signal processing can take part, e.g. using GnuRadio. The frequency range can be extended by inserting a mixer in the RF path. Its got an on-board antenna tuned for 2.5GHz, or an SMA connector can be soldered to attach an external antenna. There’s a Nokia 6100 130×130 pixel LCD and a joystick, which also featured in the earlier CCCamp 2011 badge known as the r0ket.
A 3.5mm TRRS audio connector allows hooking up a headphone and speaker easily. The LiPo battery can be charged via one of the USB ports, while the other USB port can be used for software updates and data I/O to SDR Software like GnuRadio. Check out the project details from their Github repository and more from the detailed wiki which has information on software and hardware. There’s also a Twitter account if you’d like to follow the projects progress.
This years Open Hardware Summit also promises an awesome hackable badge. We’ll probably feature it before the OHS2015 conference in September.
Thanks to [Andz] for tipping us off about this awesome Badge.
