Badges
BSides Lisbon 2025 Electronic Badge
A source-backed Portuguese Security BSides electronic-badge record: the official BSidesLisbon 2025 about page says the edition would have an electronic badge, the sponsors page lists a Badge Sponsor section for BitSight, and Eventbrite anchors the November 13-14, 2025 Auditorio FMD-UL conference.
BSides Porto 2026 Electronic Badge Experience
A conservative pre-event record for BSides Porto 2026's advertised electronic badge experience, anchored to the official site and ticketing page rather than component-level badge documentation.

BSides Porto 2026 Electronic Badge Experience
source-backed
CTF-adjacent conference context
The same official sources place the badge experience alongside a Capture The Flag competition, technical talks, hands-on workshops, and networking, but do not yet expose badge-specific challenge mechanics.

39x9 RGB LED matrix
The CADLAB README describes a 39x9, 351-LED matrix as the badge's main display surface.
Operational history
Issues & Camp Impact
The official CTF page says there were no physical challenges in 2025, and the sponsors page proves the BitSight Badge Sponsor slot but not the badge design, sponsor-logo placement details, or production vendor.
The record avoids turning the electronic badge into a proven badge-CTF platform or adding unsupported physical-design claims.
The badge archive proves the badge hardware and 2019 Pixels Camp relationship; separate event sources prove the March 21-23, 2019 Lisbon event details.
The dossier keeps hardware claims tied to the project archive and event claims tied to Pixels Camp and Portuguese event coverage.
The public README states the firmware goal and custom-firmware possibility, but the current source trail does not prove a final attendee firmware release, app ecosystem, or shipped software image.
The catalogue describes the software surface conservatively as an intended web-connected scrolling-text target.
No public schematic, PCB, BOM, firmware repository, flashing workflow, challenge binary, radio/display/power details, or badge-team writeup was recovered in this pass.
Component and software claims remain intentionally withheld until artifact-level sources appear.
The recovered public sources prove an electronic badge and Badge Sponsor category, but do not describe a PCB, firmware, soldering project, badge app, QR workflow, lanyard design, production quantity, challenge integration, or exact physical badge design.
The catalogue records the electronic-badge programme while withholding unsupported component, software, distribution, and interaction claims.
The CADLAB project shows images and renders, but no image is published because badge.gallery still needs an explicit reusable license, attribution string, source URL, and processing notes for any public badge image.
The Portugal badge record remains source-backed and image-free rather than copying CADLAB, event, or press imagery without complete rights provenance.
No BSidesLisbon 2025 badge image is published because the recovered official pages, sponsor logos, ticketing graphics, and event media do not provide a specific badge photo or official raster with reusable license or explicit permission, attribution, source URL, and processing provenance.
The Portugal record remains source-backed and image-free rather than copying sponsor logos, event-page media, ticketing screenshots, or generated badge art.
No BSides Porto 2026 Electronic Badge Experience image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.
The Portugal record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
The public source trail advertises an electronic badge experience before the event, but does not prove final shipped hardware, distribution scope, production quantity, or attendee handling.
The catalogue marks the record as planned/pre-event and should be refreshed after BSides Porto 2026 if badge-team documentation appears.
