I have arrived in Las Vegas for Defcon and Black Hat (not in that order). I love Defcon. I believe this will be my 8th year at the 'con. I've been covering it for Wired since last year and for my own blog the year before.
I also posted a sneak peek of the Defcon 16 badge on Wired.com earlier this week. I can't wait to get my hands on a production version.
A nice selection of supplies covers my bed including 8 SD cards (for friends), IR LEDs, a soldering station, a bare bones arduino, a breadboard, various components and Maker's Mark.
