DC503 Wagon Party Badge

The DC503 Wagon Party badge is a source-backed party badge documented by the no-visible-license `pdxbadgers/wagonparty` repository, whose README calls the target a badge and whose firmware advertises a `503WAGON` BLE device with OLED game modes.

Lifecycle

Add-ons & Upgrades

DC503 Wagon Party Badge source-backed

badge game

Hunter and Bender minigame

The hunt loop moves a hunter sprite, tracks laser direction from input pins, draws a Bender sprite, and increments score on hits.

Compatibility: DC503 Wagon Party Badge

badge game

Wagon animation and mileage mode

The wagon loop draws wagon and mountain sprites, prints the current banner, and increments a displayed score in miles.

badge software behavior

Three-mode firmware shell

The main loop cycles between wagon, hunt, and party modes when the mode input changes, keeping the badge centered on local interactive display behavior.

display mode

Party scroll mode

The party loop displays the BLE banner, flips display inversion, and periodically chooses random scroll directions.

display subsystem

SSD1306 128x64 OLED display

The README requires SSD1306 128x64 configuration, and the firmware initializes an Adafruit_SSD1306 display at I2C address 0x3C.

wireless interaction

BLE 0503 banner characteristic

The firmware advertises 503WAGON and exposes a BLE service and writable characteristic UUID 0503 that updates the on-screen banner text.

Operational history

Issues & Camp Impact

DC503 Wagon Party Badge note

hardware-source caveat · source-backed but incomplete · needs deeper production archive

The repository preserves firmware and programming instructions, but this pass did not recover schematics, board files, BOM, final production quantity, handout list, or a photographed final badge set.

Hardware claims stay limited to the README programming workflow, nRF52832 target, SSD1306 display setup, I2C pin mapping, and firmware-observed inputs.

DC503 Wagon Party Badge note

missing rights-cleared image · local project policy · needs licensed original replacement

No Wagon Party image is published because this pass did not identify a physical documentary badge photo or official reusable raster render with complete source URL, license or permission basis, attribution, and processing notes.

The entry remains source-backed and image-free rather than copying repository sprites, image assets, social photos, generated art, screenshots, or placeholder visuals.

DC503 Wagon Party Badge note

no visible repository license · GitHub repository metadata · documented

GitHub reports no repository license for pdxbadgers/wagonparty, so the source tree is used as public evidence but not as permission to republish images or derivative visual assets.

The record links to upstream files while leaving the hero image empty and avoiding local copies of sprites or image assets.

DC503 Wagon Party Badge note

party-badge classification · repository metadata and README · documented

The source trail describes a DC503 Wagon Party badge archive, not an official DEF CON admission badge or a BSidesPDX conference credential.

The catalogue models the artifact as a DC503 party badge and keeps it separate from DEF CON, BSidesPDX, and later DC503 Banglet/5ohBEE lineages.

DC503 Wagon Party Badge note

sprite-artwork license boundary · public repository archive · documented

The repository includes generated sprite/image assets and source comments naming image2cpp and ezgif, but this does not establish a reusable badge-photo license, upstream render permission, or attribution record for catalogue publication.

Sprites remain source evidence for firmware behavior only and are not promoted into `Public/images/`.
