Zombie Badges Take Over Security Con

We can’t get enough of hacker-con badges. BSides Cape Town, held Last December, featured an IR-equipped badge that immersed attendees in a game while they chatted.

A group led by [AndrewMohawk] and [ElasticNinja] designed the badge around an ESP8266 and 128×64 OLED display, with eight buttons, an IR receiver and transmitter, five “level” LEDs, an RGB LED, and a 600 mAh LiPo that charged over USB.

The hardware was designed specifically to play an organic game so that the organizers could watch the interaction between the badges in real time. Each badge was randomly sorted into a faction, either red, blue, or green—identifiable by an RGB LED glowing on the badge. There was also a series of five LEDs signifying your level in the game. When two or more badges got close to each other, enough for the IR to link, the badge with the lowest level was converted to the faction of the winner.

Of course, the badge displayed attendees’ handles and contained a list of convention programming. It also presented attendees with a series of challenges, which could be unlocked to play Pong or Rock/Paper/Scissors/Lizard/Spock, scan for wireless networks, and run animations.

Hacking the Thotcon 0x8 Badge

[Kenjo] attended Chicago’s Thotcon this past week and has started hacking the convention badge and detailing what he learned. Thotcon’s badge, designed by [Jedha] and programmed by [John Wallis] of Workshop 88, is packed with the requisite electronic hardware and cryptic clues. There are four NeoPixel LEDs, three pots, and a micro USB, all run by an ATmega32u4.

The stock firmware is a game called tesserHack, a maze game using the three pots for navigation. You can also connect via USB to play through the serial console, and this version includes a map view and help menu.

[Kenjo] who previously hacked the Thotcon 0x6 badge, accidentally deleted the stock firmware on this year’s badge, so he used a Bus Pirate as an ISP to burn the Arduino boot loader back on, and has started mapping out the pots and LEDs. If you’re interested in helping out, check out the project on Hackaday.io. [Thanks, gigawatts]

The SHA2017 Badge Revealed

It’s that excellent time of year in which one slowly comes to the realisation that the summer’s eagerly anticipated events are now no longer at some impossibly distant point in the future, but in fact only a matter of a few months or even weeks away. For our European readers, this means that August’s SHA2017 hacker camp is appearing on the horizon, four days of outdoor technological indulgence for our community in a scout camp on the Dutch polders.

As it is a tradition of such events to have an electronic badge incorporating ever more impressive levels of computing power, it follows that the pre-production announcement of an event badge has become an important milestone in the countdown to the day. SHA2017 is no exception, and thus today we see the announcement of their take on the essentials for a hacker camp badge in 2017.

The most immediately obvious thing about the badge is its 296×128 pixel e-ink display, which should provide an immediate benefit in terms of battery life. There are the usual plethora of interfaces, GPIOs, USB, and Neopixels, and the user input is via a set of capacitive buttons. Powering the device is an ESP32, and a key design goal was to have a network for the badges that does not put pressure on the 2.4GHz infrastructure. We’re guessing they’re doing this using raw WiFi packets in the same way as the MAGfest swadge. On the software front it will provide a straightforward development route via MicroPython, and there will be an app library for those without the inclination to code their own. You can get an early look at the schematic from the project repo (PDF).

Their target is to have the badge ready and with stable software on day 1 of the event, a laudable aim if they can manage it.

Members of the Hackaday team will be making the trip to the Netherlands for SHA2017, we look forward to seeing you if you attend too, and please show us anything interesting you do with your badges! Keep your eyes peeled for the Jolly Wrench, and come say hello. You’ll find me with the OxHack contingent and giving a talk on the kit biz which I have also published in the Project to Kit series of articles.

We’ve covered so many badges here at Hackaday that we could almost serve of a retrospective exhibition of the art form. Of particular interest to us though is our own [Voja Antonic]’s badge for last year’s Hackaday SuperConference.

Thanks [Sebastius] for the tip.

The Cubic Cyphercon Badge

Last week in Milwaukee was Cyphercon, Wisconsin’s premier hacker conference. You can’t do a hacker con without either an electronic conference badge or a 45 hanging off a lanyard, and the Cyphercon 2017 badge doesn’t disappoint. It’s an electronic cube, lovingly designed by the folks at tymkrs. It’s also a puzzle box with security holes and wireless communications. It’s a mesh network of badges, and one of the best conference badges we’ve ever seen.

The most obvious feature of the Cyphercon 2.0 badge is the extra dimension. From the outset, the design of this badge was a 3-dimensional cube, constructed out of beautifully crafted PCBs and soldered together at the edges. The techniques to bring PCBs into the third dimension are really nothing new — we’ve seen 3D PCBs before — but never at this kind of volume. There were over four hundred badges constructed for Cyphercon, and every single joint was hand-soldered. This is something your assembly house just won’t do, and I would hate to think about the poor solder monkeys that would be forced to assemble 3D badges for a larger con.

3D isn’t the only trick up the Cyphercon badge. There are cutouts in each side of the cube exposing LEDs, microprocessors, busses, and a single USB port. This USB port allows the wearer to recharge the battery, yes, but if you install a terminal emulator on your laptop and plug in the badge, you’re dropped into a world of mystery, intrigue, and suffocation. This badge is a text adventure game, with the goal of a game to reassemble a relay-based computer from parts scrounged from around a missile silo. Once the relay computer is complete, the badge turns into an emulator for a vintage time-sharing operating system. In this OS, you’re able to write code and deploy it to other badges. This is seriously impressive stuff.

Between the cubic Cyphercon badge, the Hunter S. Rodriguez badge heading to Vegas this summer, and badges that are Nintendo emulators, this is looking like a great year for electronic conference badges. The artistry and skill here is amazing, and we can’t wait to see what else the community will come up with.

Below, you can check out a few videos on the Cypbercon badge. [Wire]’s explanation of how the badge was created over the last nine months is in there, as is the Cyphercon badge panel talk.

Hardware Tribes Growing Up Around Artisanal Electronics

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.

A Real Star Trek Communicator Badge

Star Trek has never let technology get in the way of a good story. Gene Roddenberry and the writers of the show thought up some amazing gadgets, from transporters to replicators to the warp core itself. Star Trek: The Next Generation brought us the iconic communicator badge. In 1987, a long-range radio device which could fit in a pin was science fiction. [Joe] is bringing these badges a bit closer to the real world with his entry in the 2017 Hackaday Sci-Fi Contest.

trek-thumbThe first problem [Joe] dealt with was finding a radio which could run from watch batteries, and provide decently long-range operations. He chose the HopeRF RFM69HCW. Bringing fiction a bit closer to reality, this module has been used for orbital communications with low-cost satellites.

The Badge’s processor is a Teensy LC. [Joe] is rolling his own Teensy, which means using bootloader chips from PJRC, as well as the main microcontroller. Kicking the main micro into operation is where [Joe] is stuck right now. Somewhere between the breadboard and the first spin of the surface mount PCB things went a bit sideways. The oscillators are running, but there are no USB communications. [Joe] is trying another board spin. He made a few improvements and already has new boards on the way. Switching to a toaster oven or skillet paste and solder setup would definitely help him get the new badges up and running.

The Best Conference Badge Of 2017 Is A WiFi Lawn

It’s February, conference season hasn’t even started yet, and already there’s a winner of the best electronic badge of the year. For this year’s MAGfest, [CNLohr] and friends distributed 2,000 ESP8266-based swag badges.

These custom #badgelife badges aren’t. Apparently, MAGFest wouldn’t allow [CNLohr] to call these devices ‘badges’. Instead, these are ‘swadges’, a combination of swag and badges.  On board theses swadges is an ESP-12, a quartet of RGB LEDs, and buttons for up, down, left, right, A, B, Select, and Start. The swadge is powered by two AA batteries (sourced from Costco of all places), and by all accounts the badge was a complete success.

[CNLohr] is one of the great ESP8266 experts out there, and one of the design goals of this badge is to have all of these swadges communicate over raw WiFi frames. This turned out to be a great idea – using normal WiFi infrastructure with two thousand badges saturated the spectrum. The control system for was simply three badges, one per WiFi channel, that tells all the badges to change the color of the LEDs.

The swadge was a complete success, but with a few hundred blinkey glowey WiFi devices, you know [CNLohr] is going to come up with something cool. This time, he turned his lawn into a rave. About 175 swadges were laid out on the lawn, all controlled by a single controller swadge. The color of the LEDs on each swadge in the yard changes in response to the WiFi signal strength. By swinging the controller badge around his head, [CNLohr] turned his yard into a disco floor of swirling blinkieness. It looks awesome, although it might not visualize WiFi signals as well as some of [CNLohr]’s other ESP hacks.

This is a fantastic build and was well received by everyone at MAGFest. Be sure to check out the videos below, they truly show off the capabilities of this really cool piece of wearable hardware.
