ToorCon 20 Official Badge
The ToorCon San Diego 20 badge is preserved here as a 400-kit official-badge request that folded MakersBox's SMD Challenge into a larger 8-bit-art conference badge with hidden codes, eight SMD LEDs, and an ATtiny84.

source-backed
8-bit art and hidden code surface
The log says the badge carried 8-bit art plus many codes in many places while withholding the exact meanings and Gerber artwork.

ATtiny84 badge controller
The same source identifies the controller as an ATtiny84 and warns that incorrect orientation leaves the badge non-functional.

Operational history
Issues & Camp Impact
No ToorCon 20 badge image is published because the Hackaday.io project photos and screenshots have not been paired with complete original-photo provenance, explicit reuse rights, attribution, and processing notes.
The entry remains source-backed and image-free rather than copying project-gallery imagery without a clear catalogue reuse basis.
The badge record relies on a public builder log that frames the work as an official-badge request, but this pass did not recover an official ToorCon badge guide, repository, schematic set, or firmware archive.
The catalogue keeps the official-badge wording tied to the cited log and avoids claiming complete production ownership, final challenge rules, or released design files.
The builder log explicitly says the author was sworn to secrecy and forced to burn Gerber files, so the public record intentionally withholds the art secrets and full board files.
Future archive work should seek official or creator permission before treating private Gerbers, puzzle art, or code meanings as publishable catalogue evidence.
