h-c0n 2026 CTF BADge

Madrid Hackplayers electronic development-board CTF badge

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.

Why It Mattered

It adds a modern Madrid hardware-CTF badge to the worldwide compendium with primary event and public repository evidence, while keeping unrecovered board-layout, production, quantity, and image-rights claims out of the seed.

Hardware

The official badge post calls the CTF BADge a functional development board rather than only decoration, keeps rear-side component details secret before the challenge, says extra wait-list units would cost 10 EUR and be collected in person at registration, and links the badge to the February 6-7 conference pickup window. The repository readme identifies the challenge platform as RP2350/RP2354-family hardware with an SMD LED on GPIO 25, and its technical notes discuss the RP2350 RISC-V Hazard3 core and hardware debugging.

Software & Apps

The public repository provides a `ctf.uf2` firmware image for running the CTF at home on a Raspberry Pi Pico 2-compatible board, documents serial setup, picotool firmware dumping, BOOTSEL workflows, RISC-V/Hazard3 exploitation notes, debugging requirements, and three public write-ups for the first winners. The Hackplayers recap says the repository included firmware, practical tips, recommended tools, firmware-extraction notes, a RISC-V analysis environment, debugging interfaces, and dynamic-analysis material.

Lore

h-c0n is Hackplayers' hacking and cybersecurity conference in Madrid. The 2026 badge announcement says the organizers had wanted an electronic Defcon-style badge since creating the conference, and the later Hackplayers write-up credits David Reguera / Dreg with help from Adria Perez Montoro / @b1n4ri0 and Antonio Vazquez Blanco / @antoniovazquezblanco. The CTF was scheduled to start once registration opened on February 6, 2026 at 16:45 and end on February 13, 2026 at 17:00, or earlier when three participants found all flags.

Functional electronic development board

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.

Operational history

Issues & Camp Impact

missing rights-cleared image note

No h-c0n 2026 CTF BADge image is published because the official blog media, Hackplayers recap media, and repository photos have not been paired with complete reusable image rights, attribution, source URL, and processing provenance for catalogue publication.

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.

post-event source gap note

The official post intentionally withheld rear-side component details before attendees received the badge, and the later public trail improves the creator, firmware, tooling, and winner-write-up record without exposing board files, schematics, BOM, production files, final quantity, or full component identity.

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.

replay hardware boundary note

The repository says people replaying the CTF at home can flash a Raspberry Pi Pico 2, but boards different from the CTF PCB need an LED on GPIO 25 and one challenge may require a debug probe and cable.

The record distinguishes the conference CTF BADge from compatible at-home replay boards and preserves the hardware-debugging requirement without overstating universal compatibility.
