Worldwide badge coverage for Spain, grouped into seeded badges, event editions, add-ons, operational issues, resources, and evidence sources.
Seeded artifacts
A limited electronic badge made for r2con 2017 speakers and friends in Barcelona, documented by the official badge-manufacturing talk and first-hand reporting that says it showed project-status information such as build state, last commit, and GitHub stars.
A source-backed Spanish hacker-conference electronic badge record: the official h-c0n post says Hackplayers finally produced an electronic badge for the sixth 2026 edition, describes it as a fully functional development board, and ties pickup to the February 6 conference registration and CTF start; the public `therealdreg/hcon2026hwctf` repository and Hackplayers post-event write-up document RP2350/RISC-V firmware, tooling, named co-creators, and winner write-ups.
A Spanish RootedCON 2026 official Pacman Badge reconstructed from multiple community reversing repositories as an ESP32-D0WD-V3 board with a 1.77-inch ST7735 128x160 display, a directional pad, buttons, and a native quiz-server CTF protocol, distributed at the March 5-7, 2026 sixteenth edition at Kinepolis Madrid.
Events
The September 6-9, 2017 radare2 reverse-engineering congress in Barcelona, whose official schedule included NighterMan's r2con badge manufacturing talk and whose attendee reporting documents a limited speaker/friends electronic badge.
The February 5-7, 2026 Hackplayers h-c0n edition in Madrid, with workshops at Exe Madrid Norte and talks at Centro Cultural Sanchinarro, whose official post announced the CTF BADge electronic development-board challenge.
The March 5-7, 2026 sixteenth RootedCON edition in Madrid whose community reversing repositories reconstruct an official Pacman Badge ESP32 electronic badge with an ST7735 display, D-pad, and a native quiz-server CTF protocol.
Lifecycle
The first-hand writeup says the badge indicated information such as build status, last commit, and GitHub stars.
The original official badge firmware shipped a custom Pacman-themed firmware whose native quiz-server CTF protocol was reversed by the community.
The official h-c0n badge post says the CTF BADge is a fully functional development board that can be used for personal projects, not only an ornament.
The r4venOS community firmware replaces the Pacman firmware with a WiFi scanner, evil-twin detector, deauth, and crypto utility toolkit on the same ESP32 hardware.
Community reversals identify a 1.77-inch ST7735 128x160 TFT display and a directional pad with additional buttons on the ESP32-D0WD-V3 board.
The official post says participants could start the CTF when registration opened on February 6, 2026 at 16:45, with the competition ending on February 13 at 17:00 or when three participants solved every flag.
The official r2con schedule included NighterMan's badge talk covering prototyping, design, debugging, assembly, encountered problems, manufacturing, and tools.
The public hcon2026hwctf repository provides ctf.uf2 and describes RP2350/RISC-V Hazard3 exploitation challenges for the HC0N 2026 hardware CTF.
The recovered first-hand report describes the badge as fancy hardware for speakers and friends, so the record does not claim general attendee distribution.
The Hackplayers recap links the first three winner write-ups and summarizes their approaches: firmware extraction, RISC-V reversing, logical-flaw exploitation, static and dynamic analysis, validation weaknesses, and state manipulation.
The repository preserves first, second, and third winner write-ups plus serial, picotool, BOOTSEL, and debugging guidance for people replaying the hardware CTF.
Operational history
Hardware and software descriptions stay limited to what the sources explicitly support.
The compendium models the object as a limited conference artifact instead of an all-attendee badge.
The record remains image-free rather than copying social or attendee imagery without complete reuse provenance.
The Spanish h-c0n record remains source-backed and image-free rather than copying blog images, repository photos, prize photos, screenshots, logos, or generated badge art.
The Spanish record remains source-backed and image-free rather than copying community repository diagrams, screenshots, social media, placeholders, or generated approximations.
The record treats the badge as the official RootedCON 2026 badge on the strength of convergent community reversals, while keeping the official-status, designer, and production claims conservative until official sources appear.
The catalogue records only the official development-board, Hackplayers recap, and repository-backed RP2350/RISC-V challenge claims while withholding exact board-design and manufacturing claims.
The record distinguishes the conference CTF BADge from compatible at-home replay boards and preserves the hardware-debugging requirement without overstating universal compatibility.
