I just did a quick cat /dev/ttyACM0 and you get something of a color interface. The product id is listed as “Cyphercon 3.0” which is an obvious holdover from this year’s Cyphercon badge from the event held in Milwaukee back in April.
#DEFCON BADGES 2019 SERIAL NUMBER#
The manufacture is listed at “Tymkrs” with a serial number of “D00D DEAD BEEF FEED C0ED”. The GameĬonnect to the badge with a micro USB cable and it enumerates on /dev/ttyACM0. When connected, fun information is immediately available. One is located in the center of the board, another is off to the side of the board near the battery holders.Īgain, if you have an idea of what these components are, or their functionality please leave a comment. Also on the face of the board are two small 6-pin parts which are not the same. Near the top of the board is an 8-pin SOIC part which I initially thought was an EEPROM but it is actually a PIC12F microcontroller. Leave a comment if you know more about this part.
#DEFCON BADGES 2019 DRIVER#
It is likely an LED driver and the writing we were able to read was something like “T1918 3236”. To the left is another 48-pin chip that is unknown at this point. In addition to driving the badge it provides USB connectivity. The main processor is the PIC32MM0256GPM with 256 kB and 512 kB of SRAM in a 48-pin TQFP package shown to the right in this image. There are 30 of these LEDs in total some are RGB (those located under the DEF CON text) and some are single color. Those LEDs are mounted on the underside of the badge and shine through the board to illuminate the surface. This is a really interesting part of the design as the battery holders are taped to the back of the badge over the top of the microcontroller, LED driver, and many of the LEDs. The bulk and weight of the badge comes mostly from four AA batteries which are nested into two holders. Yes, there is a header for the new add-on standard on the official DEF CON badge this year. The badge is roughly eight inches tall by three inches wide and hangs around your neck by a single lanyard hole. Most importantly, become a team member of the Hackaday.io DC26 badge solving project page to help discover all that’s involved in this badge. Let’s take a look at all the goodies inside. There is no larger pressure cooker in the world of badges than this, and they pulled it off marvelously. Kudos to the dynamic hardware collective from Minnesota. Displayed proudly on the board and in the firmware, we discover that The Toymakers are the ones who have put it all on this line this year. The creators of this badge are no strangers to the Hackaday community. But the badge contest at DEF CON is legendary - solve all the puzzles you are awarded the coveted black badge. Of course there is blinky, the board is artistic, and everyone hopefully maybe gets one (it’s rumored 27,000+ were manufactured) if they don’t run out.

To the delight of everyone, this year’s official DEF CON badge is an electronic badge chock full of entertainment.
