[Daniel Valuch] shared a fun and record-setting conference badge story (Slovak, translated) with us. He was one of the organizers for the “ZENIT in electronics” event, which is an annual Slovak national competition for students. During the competition, students are assigned a letter+number code for the purpose of result submission anonymity, and organizers are always on the lookout for a fun way to assign these codes – this time, they did it with custom silicon!
It just so happened that [Peter], one of [Daniel]’s colleagues, was at the time working for onsemi who were doing a tapeout and had some free space on their test chips. Of course, they didn’t have to think twice. When it was a student’s turn to draw their identification number, instead of a slip of paper, they received a SOIC-16 package with custom silicon bonded to it. Then, they had to solder it to their competition badge – which was, of course, a PCB. Each chip was individually laser-trimmed to contain the student’s number, and that number could then be decoded using a multimeter – or a reasonably sharp eye.
There’s way more to this competition story than just the badge, but the custom silicon part of it sure caught our eyes. Who knows, maybe next year stars will align again and we’ll see custom silicon on one of the hacker conference badges. After all, things have been advancing rapidly on that front – for instance, since Skywater PDK project’s inception in 2020, there’s been several successful runs already, and if you’d like to learn more, you could check the HackChat we’ve had this year, and this Remoticon 2020 workshop!
PCB badges have exploded in popularity in recent years. Starting out as a fun token of entry to a conference, they’re now being developed by all manner of independent groups, with DEFCON serving as the heart of the #badgelife movement. After DEFCON 26, Kate Morris and associates decided to undertake the development of their own badge, to celebrate the 50th anniversary of the Apollo landing. Kate’s talk at the 2019 Hackaday Superconference serves to tell the tale of creating a retro game to run on a badge platform.

Today, nearly every modern consumer device wants to connect to the Internet for some reason. From your garage door opener to each individual smart bulb, the Internet of Things has arrived in full force. But the same can’t be said for most of our beloved conference badges. Wanting to explore the concept a bit, [Ayan Pahwa] set out to create his own MQTT-connected badge that he’s calling CloudBadge.
As this was more of a software experiment, all of the hardware is off-the-shelf. The badge itself is an Adafruit PyBadge, which doesn’t normally have any networking capabilities, but does feature a Feather-compatible header on the back. To that [Ayan] added a AirLift FeatherWing which allows him to use the ESP32 as a co-processor. He also added a strip of NeoPixel LEDs to the lanyard, though those could certainly be left off if you’re not looking to call quite so much attention to yourself.
The rest was just a matter of software. [Ayan] came up with some code that uses the combined hardware of the PyPadge and ESP32 to connect to Adafruit.io via MQTT. Once connected, the user is able to change the name that displays on the screen and the colors of the RGB LEDs through the cloud service. If you used something like this for an actual conference badge, the concept could easily be expanded to do things like flashing the badge’s LEDs when a talk the wearer wanted to see is about to start.
The modern conference badge has come a long way from simple blinking LEDs, offering challenges that you’ll likely still be working on long after the event wraps up. Concerns over security and the challenge of maintaining the necessary infrastructure during the event usually means they don’t include networking features, but projects like CloudBadge show the idea certainly has merit.

Through the weekend Twitter has been a-titter with news coming out of Saintcon, the annual security conference in Provo, Utah. Now that the weekend is over we can finally get our hands on full hardware and software sources for the curvy, LED-covered badge we’ve been salivating over and a write up by its creators [compukidmike] and [bashNinja]. Let’s dive in and see what’s waiting!
This year’s badge is designed to represent a single tooth on a single rotor of an Enigma machine. The full function of an Enigma machine is quite complex, but an individual device has three rotors with 26 teeth each (one for each letter) as well as a keypad for input and a character display to show each enciphered letter. For reference, the back of the badge has a handy diagram of a badge’s place in the Enigma system.
Reminiscent of the WWII device which the badge design recalls, each unit includes a full QWERTZ keyboard (with labeled keys!) and RGB “lampboard” for individual character output, but unlike the original there’s also a curved 16 x 64 RGB LED display made from those beguiling little ~1mm x 1mm LEDs. All in, the device includes 1051 LEDs! Combined with the unusually non-rectilinear shape of the badge and the Enigma-style Saintcon logo it makes for an attractive, cohesive look.

Blade Runner showed us a dystopian megatropolis vision of Los Angeles in the far-off future. What was a distant dream for the 1982 theater-goes (2019) is now our everyday. We know Los Angeles is not perpetually overcast, flying cars are not cruising those skies, and replicants are not hiding among the population. Or… are they?
The LayerOne conference takes place in greater Los Angeles and this year it adopted a Blade Runner theme in honor of that landmark film. My favorite part of the theme was the conference badge modeled after a Voight-Kampff machine. These were used in the film to distinguish replicants from humans, and that’s exactly what this badge does too. In the movies, replicants are tested by asking questions and monitoring their eyes for a reaction — this badge has an optional eye-recognition camera to deliver this effect. Let’s take a look!

The security conference LayerOne 2018 took place this past weekend in Pasadena, California. A schedule conflict meant most of our crew was at Hackaday Belgrade but I went to LayerOne to check it out as a first-time attendee. It was a weekend full of deciphering an enigmatic badge, hands-on learning about physical security, admiring impressive demos, and building a crappy robot.

In case you haven’t heard, the best hardware conference in the world was last weekend. The Hackaday Superconference was three days of hardware hacking, soldering irons, and an epic hardware badge. Throw in two stages for talk, two workshop areas, the amazing hallwaycon and the best, most chill attendees you can imagine, and you have the ultimate hardware conference.
Already we’ve gone over the gory details of what this badge does, and now it’s time to talk about the perils of building large numbers of an electronic conference badge. This is the hardware demoscene, artisanal manufacturing, badgelife, and an exploration of exactly how far you can push a development schedule to get these badges out the door and into the hands of eager badge hackers and con attendees.
The good news is that we succeeded, and did so in time to put a completed badge in the hand of everyone who attended the conference (and we do have a few available if you didn’t make it to the con). Join me after the break to learn what it took to make it all happen and see the time lapse of the final kitting process.
