We can’t get sufficient of hacker-con badges. BSides Cape Town, held Last December, featured an IR-equipped badge that immersed attendees in a game while they chatted.
A group led by [AndrewMohawk] as well as [ElasticNinja] developed the badge around an ESP8266 as well as 128×64 OLED display, with eight buttons, an IR receiver as well as transmitter, five “level” LEDs, an RGB LED, and a 600 mAh LiPo that charged over USB.
The hardware was developed specifically to play an organic game so that the organizers might view the interaction between the badges in real time. Each badge was randomly sorted into a faction, either red, blue, or green—identifiable by an RGB LED glowing on the badge. There was also a series of five LEDs signifying your level in the game. When two or much more badges got close to each other, sufficient for the IR to link, the badge with the lowest level was converted to the faction of the winner.
Of course, the badge displayed attendees’ handles as well as contained a list of convention programming. It likewise presented attendees with a series of challenges, which might be unlocked to play Pong or Rock/Paper/Scissors/Lizard/Spock, scan for wireless networks, as well as run animations.
