Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The wagon loop draws wagon and mountain sprites, prints the current banner, and increments a displayed score in miles.
Badge context
Repository sprite/image asset directory retained as source context only; no asset is promoted as a catalogue image because the repository has no visible license and the files are not documentary badge photos.
Main firmware source for SSD1306 display setup, BLE service and banner characteristic, 503WAGON identity, 503.PARTY default banner, wagon/hunt/party modes, and DYSENTERY/WannaCry behavior.
Public PDX Badgers repository described as dc503 wagon party, with README flashing notes, Arduino firmware, sprites, image assets, and contributor history.
External setup guide explicitly linked by the README for adding Arduino compatibility to the SparkFun nRF52832 Breakout target used by the badge workflow.
Primary setup source that calls the target a badge, specifies 3.3V USB-serial programming, SparkFun nRF52832 Arduino setup, SSD1306 128x64 configuration, I2C pin remapping, and wagon-wheel programming-mode entry.
Repository history source for README errata, flashing instructions, image-resource addition, and initial code publication in July 2017.
Sprite header source naming image2cpp and ezgif generation tools and preserving wagon, mountain, hunter, and Bender bitmap data used by the firmware.
Source trail
Primary setup source calling the target a badge and documenting the 3.3V USB-serial, SparkFun nRF52832, SSD1306, I2C pin, and wagon-wheel programming workflow.
Primary repository source for the DC503 Wagon Party badge archive, repository metadata, source tree, contributor trail, and no-visible-license image decision.
Primary sprite-source evidence for the generated wagon, mountains, hunter, and Bender graphics used by firmware, while keeping those assets out of the catalogue image archive.
Repository history source for July 2017 publication, image-resource addition, flashing-instruction updates, and README errata.
Primary firmware source for BLEPeripheral service UUID 0503, writable banner text, 503WAGON advertising, OLED setup, three game modes, input pins, DYSENTERY/WannaCry strings, and game loops.
Setup source linked by the README for the SparkFun nRF52832 Arduino compatibility path used by the badge programming instructions.
