DEF CON’s X86 Badge

August 5, 2016 by Brian Benchoff 49 Comments

This year’s DEF CON badge is electronic, and there was much celebrating. This year’s DEF CON badge has an x86 processor, and there was much confusion.

The badge this year, ~~and every year,~~ except badges for 18, 17, 16, 15, and 14, designed by [Joe Grand], and badges from pre-history designed by [Dark Tangent] and [Ping], was designed by [1057], and is built around an x86 processor. Specifically, this badge features an Intel Quark D2000 microcontroller, a microcontroller running at 32MHz, with 32kB of Flash and 8kB of RAM. Yes, an x86 badge, but I think an AT motherboard badge would better fulfill that requirement.

As far as buttons, sensors, peripherals, and LEDs go, this badge is exceptionally minimal. There are eight buttons, laid out as two directional pads, five LEDs, and a battery. There’s not much here, but with a close inspection of the ‘chin’ area of the badge, you can see how this badge was programmed.

As with any [1057] joint, this badge features puzzles galore. One of these puzzles is exceptionally hard to photograph as it is in the bottom copper layer. It reads, “nonpareil bimil: Icnwc lsrbcx kc htr-yudnv ifz xdgm yduxnw yc iisto-cypzk”. Another bottom copper text reads, “10000100001 ΣA120215”. Get crackin’.

This post has been updated to correct the record of who designed badges for previous cons.

DEFCON Thermometer

August 5, 2016 by James Hobson 22 Comments

Redditor [mulishadan] — a fan of the movie WarGames — has created a singular thermostat in the form of a Defcon alert meter.

Looking to learn some new skills while building, [mulishadan] tried their hand at MIG welding the 16g cold-rolled plate steel into the distinctive shape. A second attempt produced the desired result, adding a 1/4-inch foam core and painting the exterior. Individual LEDs were used at first for lighting, but were replaced with flexible LED strips which provided a more even glow behind the coloured acrylic. A Particle Photon board queries the Weather Underground API via Wi-Fi in five-minute intervals.

Each escalation in the Defcon alert signals an increase of 10 F, starting at Defcon 5 for 69 F and below, up to Defcon 1 for 100+ F. The final build looks like a true-to-life prop with some useful functionality that can be adapted to many different purposes — proof that a relatively simple project can still produce fantastic results for entry-level makers. So why not try making this thermostat scarf as well?
