SAINTCON
The October 20-23, 2014 SAINTCON edition in Ogden, Utah, whose first-hand attendee/project-owner write-up, SparkFun repost, and Hackaday coverage document an Arduino-compatible conference badge designed for soldering, hacking, and hidden Hacker Challenge secrets.
Ogden, Utah · United States · 2014
The SAINTCON 2014 badge was an Arduino-compatible conference badge designed for attendee soldering and badge hacking, with FTDI programming, LED blinky behavior, a companion blinky expansion board, and hidden Hacker Challenge secrets documented in first-hand and Hackaday coverage.
Lifecycle
Hackaday describes attendees receiving a bag of components and assembling the badge in the Hardware Hacking Village soldering environment.
The first-hand write-up documents a custom blinky board by Luke Jenkins and Klint Holmes that extended the badge-hacking experience.
Datko says Matt Lorimer found one of the SAINTCON secrets by examining the badge source code, tying the badge to the Hacker Challenge trail.
Cisco's 2015 write-up frames SAINTCON's show-badge program as having run across the prior two years, supporting 2014 as part of the event's early badge lineage.
Datko and Hackaday describe the SAINTCON 2014 badge as an Arduino clone or Arduino-compatible badge built for attendee hacking.
The badge could be programmed through an FTDI header, giving attendees a direct Arduino-style code-loading path.
Operational history
The entry remains source-backed and image-free rather than copying blog, SparkFun, Hackaday, or event media without explicit reuse permission.
The United States record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
The record preserves verified badge behavior and named-source context without inventing unrecovered electronics, firmware internals, component values, or manufacturing details.
