Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The 3D-print README documents soft flexible and hard hinged bangle shells for holding the electronics, with magnets, hinge wire, and heat-shrink retention.
Badge context
Eagle board source for the DC503 2018 Banglet hardware archive.
BLEUART interaction sketch documenting commands such as list, rainbow, patriot, and off for badge interaction experiments.
Main firmware source for BLEUART service, scanner behavior, unique names, NeoPixel output, `/list` interaction, and party-badge operation.
Sketch documentation source describing the Feather-style nRF52/Bluefruit board, NeoPixel data on A0, and Arduino/Adafruit setup path.
Public PDX Badgers repository for the DEFCON 26 DC503 VIP Banglet wrist badge, with README, license, Eagle CAD, firmware sketches, and 3D-print files.
Repository Apache-2.0 license file; used as project-code/documentation licensing evidence, not as a cleared badge-photo source.
Repository mechanical source describing soft and hard bangle shells, clear flexible material, hinge wire, magnets, and heat-shrink retention.
Official speaker page source stating that the DC503 badge was a Bluetooth LE bangle rather than a neck badge.
Official schedule source placing Nisha Kumar's Making of the Banglet talk after the BSidesPDX 101 session.
Primary repository README for the wrist-badge premise, Bluetooth recon and hidden-party-mode framing, team credits, and Adafruit acknowledgement.
Eagle schematic source for the DC503 2018 Banglet hardware archive.
