BSidesPDX 2020 Presenter LED Mask

A source-backed BSidesPDX 2020 presenter wearable artifact documented by the public PDX Badgers `2020-mask` repository, built as a voice-reactive LED face-mask project for the all-digital conference year rather than a conventional attendee badge.

Lifecycle

Add-ons & Upgrades

BSidesPDX 2020 Presenter LED Mask source-backed

audio input

MAX4466 microphone voice input

The README lists a MAX4466 microphone module, and the firmware samples A0 to choose mouth frames based on detected voice volume.

Compatibility: BSidesPDX 2020 Presenter LED Mask

distribution context

Presenter-gift artifact context

The repository description and firmware comments frame the mask as a BSides 2020 presenter gift rather than a general attendee badge.

firmware workflow

Adafruit NeoMatrix firmware stack

The README requires Adafruit NeoMatrix, Adafruit NeoPixel, and Adafruit GFX libraries, while the sketch uses NeoMatrix drawing primitives for scrolling text and pixel mouth images.

hardware architecture

Arduino Pro Micro wearable core

The README describes the BSidesPDX mask modification as using an Arduino Pro Micro-class board with ATmega32U4 and USB Micro instead of the original Arduino Nano approach.

Operational history

Issues & Camp Impact

BSidesPDX 2020 Presenter LED Mask note

artifact-classification caveat · repository description and source comments · documented

The public repository describes the item as a talking LED mask for BSides 2020 presenters, and the firmware comments call it a BSides PDX speaker gift; no source recovered here says it was the attendee badge.

The catalogue models the object as a presenter wearable/event artifact rather than a general admission badge or attendee-wide distribution claim.

BSidesPDX 2020 Presenter LED Mask note

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

No BSidesPDX 2020 presenter LED mask image is published because this pass did not recover a physical documentary photo or 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 repository screenshots, event-page images, social photos, product photos, or generated visuals.

BSidesPDX 2020 Presenter LED Mask note

repository-license caveat · GitHub repository metadata · needs explicit license recovery

GitHub reports no repository license for `pdxbadgers/2020-mask`, 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 source files as a reusable image basis.

BSidesPDX 2020 Presenter LED Mask note

technical-source caveat · public firmware and README archive · needs final production archive

The public repository exposes README wiring notes and one Arduino sketch, but this pass did not recover fabrication notes, final quantity, presenter handout list, production photos, source license, or post-event maintenance history.

Hardware and software claims remain limited to the public repository files and official all-digital event context.
