Ninja Networks
The 2009 Ninja Networks DEF CON party edition whose electronic invitation badge was built in a 500-unit hand-assembly sprint and later published with schematic, Gerber, BOM, and public-domain firmware archives.
Artisan Hotel, Las Vegas, Nevada / DEF CON 17 · United States · 2009
Ninja Networks' 2009 DEF CON party invitation was an electronic badge built for DEF CON 17, documented by a primary DEF CON forum post plus a technical archive with Creative Commons Attribution schematic/Gerber docs, public-domain badge code, and a BOM.
Lifecycle
The forum narrative says the team used solder paste, a hotplate, and manual display insertion to finish about 500 functional badges before the party.
The technical archive links the badge source-code tarball and labels the code as public domain.
The technical archive publishes schematic and Gerber documentation and states that the documentation is Creative Commons Attribution licensed.
Ninja Networks built the DC17 badge as the electronic invitation artifact for its DEF CON-adjacent party at the Artisan Hotel.
Operational history
The badge page describes the published public-domain source and visible electronic invitation hardware without upgrading abandoned goals into production behavior.
The record stays source-backed and image-free rather than copying social, article, video-frame, generated, placeholder, or uncleared media.
The compendium keeps the unofficial party-badge lineage separate from the official DEF CON badge series while preserving its badgelife significance.
