BSidesPDX 2018 ATTiny861 Badge

ATTiny861 LED and SAO badge archive

The BSidesPDX 2018 badge is a source-backed Portland Security BSides badge archive tied to the official BSidesPDX 101 badge panel and the public PDX Badgers KiCad, BOM, LED mapping, and ATTiny861 firmware archive.

Why It Mattered

It fills the Portland Security BSides lineage between the 2015 Badger and 2019 Multnomah records with a primary-source hardware/software archive while keeping image and license claims constrained to recoverable evidence.

Hardware

The `badge-2018` repository preserves KiCad board, schematic, project, library, Gerber outputs, BOM, and datasheet paths. The BOM lists an ATTINY861A-XUR/ATTINY861-class SOIC-20 controller, 12 yellow LEDs, four RGB LEDs, two zener diodes, USB Micro-B connector, two switches, CR2032 battery, battery retainer, and lanyard item. The firmware README maps four charlieplex rows, four RGB enables, RGB PWM pins, SAO SDA/SCL, SPI pins, USB D-/D+, and left/right switch pins.

Software & Apps

The firmware README documents ATTinyCore/Arduino setup, micronucleus USB bootloader workflow, sample programs, board-test firmware, and pin mappings. The public `boardtest.ino` cycles PWM RGB channels and charlieplexed LEDs, while `led_mapping.csv` maps icon LEDs such as mountain, coffee, rain, bridge, sasquatch, book, train, beard, bike, donut, rose, and beer.

Lore

The official Friday schedule places BSidesPDX 101 at 11:00 on October 26, 2018 with a title covering CTF, contests and events, badges, and more; the speaker page says the panel discussed the thing around attendees' necks. A separate 11:30 talk covered the DC503 Banglet, so this record keeps the BSidesPDX 2018 conference badge archive separate from that party-badge lineage.

Issues & Camp Impact

distribution-scope caveat note

The official schedule and speaker page prove 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 2018 badge archive without overclaiming distribution scope.

lineage-boundary caveat note

The BSidesPDX 2018 schedule also lists The Making of the Banglet, and PDX Badgers has a separate Apache-2.0 `2018-banglet` repository for a DEFCON 26 / DC503 VIP wrist badge.

This record covers the BSidesPDX 2018 conference badge archive in `badge-2018`; the DC503 Banglet is modeled separately as its own DEF CON-adjacent party-badge lineage record.

missing rights-cleared image note

No BSidesPDX 2018 ATTiny861 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, sponsor logos, event-page imagery, social photos, screenshots, or generated visuals.

technical-source caveat note

The public repository exposes KiCad, BOM, LED mapping, and test firmware files, but this pass did not recover final firmware release notes, challenge docs, production photos, or a full talk transcript explaining intended gameplay.

Hardware and firmware claims remain limited to the public repository files and official schedule/speaker wording.
