Michael Ossmann Pulls DSSS Out of Nowhere

[Michael Ossmann] spoke on Friday to a packed house in the wireless hacking village at DEF CON 25. There’s still a day and a half of talks remaining but it will be hard for anything to unseat his Reverse Engineering Direct Sequence Spread Spectrum (DSSS) talk as my favorite of the con.

DSSS is a technique used to transmit reliable data where low signal strength and high noise are likely. It’s used in GPS communications where the signal received from a satellite is often far too small for you to detect visually on a waterfall display. Yet we know that …read more http://pje.fyi/PbZmyw

Sunday: Breakfast at DEF CON

Nurse your hangover by having Breakfast at DEF CON with Hackaday this Sunday. You’re invited to our yearly ritual by marking the beginning of the end with coffee and pastries at 10:30 am.

Choosing an exact location in advance is always tricky (anyone who’s been to DEF CON understands). We’ll pick a place once we hit town later this week. For now, head over to the Breakfast at DEF CON event page and hit the “join the team” button on the bottom left so we can let you know when we’ve found the perfect location for the breakfast meetup.

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 …read more http://pje.fyi/PX55nS

Badge from Diamond Age Comes to DEF CON

We’re huge fans of [Neil 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 …read more http://pje.fyi/PVkVP0

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 …read more http://pje.fyi/PTkTFf

DEF CON Badgelife: The Puffy That Runs Linux

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 …read more http://pje.fyi/PT1MFB
