Why It Mattered

It adds Portugal to the European badge map and shows a local hackathon/technology event producing a real open hardware-style badge rather than only web badges, tickets, or ordinary registration artifacts.

Hardware

The public CADLAB archive describes a two-board badge made for the 2019 Pixels Camp edition: a 39x9, 351-LED matrix driven by an IS31FL3741, controlled by an ESP32 with WiFi/Bluetooth, USB-to-serial through CH340G, NCP708 regulation, MCP73831 LiPo charging, USB and 1S LiPo power, and Altium design files for the matrix, control, panel, schematics, Gerbers, and BOM material.

Software & Apps

The README frames the main firmware goal as a web-connected scrolling text display while explicitly allowing custom firmware versions; no shipped attendee firmware repository is claimed beyond the public code/design archive.

Lore

Pixels Camp's official FAQ frames the event as a Lisbon hacker-spirit technology gathering with talks, workshops, competitions, and a 48-hour hackathon. Portuguese coverage anchors the 2019 edition at Pavilhao Carlos Lopes from March 21 to 23, 2019.

Operational history

Issues & Camp Impact

event-source split note

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.

Confidence: mixed source trail
Status: documented
Timeframe: 2019 edition
Source note: CADLAB, Pixels Camp FAQ, Shifter, and PCGuia.

firmware archive gap note

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.

Confidence: project README
Status: needs deeper recovery
Timeframe: post-event archive
Source note: CADLAB README excerpt.

missing rights-cleared image note

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.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy and CADLAB project page.
