BSidesPDX 2019 Multnomah Badge
The BSidesPDX 2019 Multnomah badge is a source-backed Portland Security BSides badge archive tied to the official schedule's badges-and-contests context and the public PDX Badgers KiCad, BOM, and firmware repository.

official schedule
BSidesPDX 101 badges context
The official schedule says BSidesPDX 101 covered CTF, contests and events, badges, and more on Friday morning.
BSidesPDX 2019 Multnomah Badge
source-backed
Two-channel PWM LED animation
The firmware defines two PWM pins and repeatedly writes sine/cosine-derived brightness values, giving the LED badge a simple animated lighting pattern.
BSidesPDX 2019 Multnomah Badge
source-backed
ATtiny85 LED badge core
The repository BOM lists an ATtiny85-20SUR microcontroller and 24 blue side-view LEDs as the badge's main active components.
BSidesPDX 2019 Multnomah Badge
source-backed
KiCad Multnomah hardware archive
The repository preserves the Multnomah KiCad PCB, schematic, project, netlist, footprint table, symbol table, and local footprint directory.

CR2032 and slide-switch power path
The BOM lists a CR2032 battery holder and DPDT slide switch for the badge's portable power/control hardware.
Operational history
Issues & Camp Impact
The official schedule proves a badges-related BSidesPDX 101 session and the repository proves a badge archive, but this pass did not recover an attendee-wide distribution statement, quantity, assembly note, or final handout logistics.
The catalogue records a source-backed BSidesPDX 2019 badge archive without overclaiming distribution scope.
No BSidesPDX 2019 Multnomah badge image is published because this pass did not recover a physical documentary photo or full official upstream raster render with source URL, license or permission basis, attribution, and processing notes.
The entry remains source-backed and image-free rather than copying board files, logos, event-page imagery, social photos, screenshots, or generated visuals.
GitHub reports no repository license for `pdxbadgers/badge-2019`, and no top-level LICENSE file was recovered in the repository listing.
The catalogue cites the repository as evidence but does not republish repository media or treat the design files as reusable image assets.
The public repository exposes KiCad, BOM, and simple firmware files, but this pass did not recover assembly instructions, final firmware release notes, challenge docs, production photos, or talk notes explaining intended gameplay.
Hardware and firmware claims remain limited to the public repository files and official schedule wording.
