Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The first-hand write-up documents a custom blinky board by Luke Jenkins and Klint Holmes that extended the badge-hacking experience.
Badge context
Hackaday coverage source for the Arduino-compatible badge, bag-of-components distribution, HHV assembly workflow, FTDI header, challenge secrets, and blinky-board add-on context.
Josh Datko first-hand source for the SAINTCON 2014 badge, Arduino-clone framing, FTDI programming, HHV soldering context, hidden source-code secret, blinky expansion board, and designer/support credits.
SparkFun repost/context source for the October 20-23, 2014 Ogden event window and badge-hacking narrative.
Cisco's 2015 write-up frames SAINTCON show badges as a two-year program, used here only as lineage context rather than as a source for unrecovered 2014 electronics details.
Source trail
Retrospective SAINTCON show-badge lineage context; not used to infer unrecovered 2014 component or firmware details beyond the existence of prior-year show-badge activity.
Secondary coverage source corroborating Arduino-compatibility, FTDI header, bag-of-components distribution, HHV soldering, blinky board, and hidden challenge behavior.
First-hand badge source for the Arduino-compatible SAINTCON 2014 badge, FTDI programming, hidden Hacker Challenge code, blinky board, and named contributors.
SparkFun repost/context source for the October 20-23, 2014 Ogden event and badge-hacking write-up trail.
