Nuit du Hack / leHACK

leHACK 2026

The June 26-28, 2026 leHACK edition in Paris, represented by the scheduled Badge Hackropole assembly workshop in the new leLAB Hardware Village. Official leHACK and ANSSI publications document ten 55-minute sessions on June 26-27 to assemble and program a capacitive ESP32-S3/WS2812B light-up badge, while FCSC-FR's public repository carries the hardware, assembly, and WLED documentation. The record treats the device as a workshop artifact rather than a general conference credential, and does not assume individual attendance, finished assembly, or handoff.

leHACK 2026 Badge Hackropole

leHACK's official 2026 workshop schedule and the French National Cybersecurity Agency's leHACK listing present Badge Hackropole as a novice-accessible workshop in which participants assemble a capacitive light-up badge, solder a microcontroller and eight SMD LEDs, and program preconfigured WLED firmware. FCSC-FR's public hackropole-badge repository supplies the PCB source, assembly instructions, firmware binaries/configuration, and per-file licensing. The programme lists ten 55-minute workshop sessions across June 26-27, but the source trail does not prove final attendance, completed builds, or a conference-wide handout.

Lifecycle

Add-ons & Upgrades

leHACK 2026 Badge Hackropole public source guide

firmware workflow

WLED v0.15.5 flash and Wi-Fi setup

The source guide aligns the distributed firmware with WLED v0.15.5, documents ESP32-S3 bootloader flashing with esptool, a WLED Wi-Fi access-point onboarding flow, a web interface, and touch controls for lighting and effects.

Compatibility: Hackropole source-tree workflow; it is not evidence of an event-specific application, CTF, backend, account, final firmware state, or support/update service for every workshop artifact.

leHACK 2026 Badge Hackropole official programme

hands-on workshop access

Beginner leLAB workshop model

leLAB identifies Badge Hackropole soldering as an introductory activity with no technical prerequisite; workshop sign-up was on site, first come first served, and groups were limited to ten people maximum.

Compatibility: leLAB workshop context only; it does not establish that every leHACK attendee or registrant participated or received a badge.

hardware interaction and modification surface

Capacitive control and GP14/GP15 mod surface

The WLED guide maps eight capacitive pillar controls and a rooster-crest touch control, and exposes GP14/GP15 pads for user modifications such as 3.3 V I2C sensors or an I2S microphone.

Compatibility: Public Hackropole configuration only; no source establishes a particular attendee modification, sensor, microphone, enclosure, pin safety review, or support commitment.

official build guide

ESP32-S3-Zero and WS2812B assembly baseline

The assembly guide recommends one Waveshare ESP32-S3-Zero without pin headers and eight WS2812B LEDs in 5050-SMD packages as the baseline working board.

Compatibility: Hackropole public design baseline; optional lanyard, USB power bank, stand, and sensor additions are not universal event-issued parts or compatibility guarantees.

official workshop schedule

Ten scheduled 55-minute Badge Hackropole sessions

ANSSI's official leHACK listing schedules ten 55-minute Badge Hackropole workshop sessions: five on June 26 and five on June 27.

Compatibility: leHACK 2026 Badge Hackropole workshop activity only; the published schedule does not prove which sessions ran, attendance, completed builds, kit allocation, or final handoff.

Operational history

Issues & Camp Impact

conference credential separation · official leHACK practical information · workshop device and general badge pickup documented as distinct contexts

leHACK's practical-information page says reception staff issued a general conference badge when a QR code was presented. Badge Hackropole appears separately in the leLAB workshop schedule and hardware repository; no reviewed source says it was the admission badge, QR credential, access-control token, attendee-wide inclusion, or replacement for the general conference badge.

The record remains a workshop-made electronic artifact rather than an unsupported claim about leHACK admission, identity, access control, or universal badge allocation.

final configuration and firmware lifecycle boundary · public build and firmware documentation · design and baseline firmware public; event-specific final state unpublished

The sources document a baseline ESP32-S3-Zero/eight-LED configuration and WLED v0.15.5-aligned binaries, but do not establish each workshop unit's exact component source, board revision, solder quality, power source, flashed binary, Wi-Fi/client configuration, customization, firmware update history, security review, or post-event maintenance path.

Readers can reproduce the documented public design without mistaking one source configuration for a verified event-wide production, security, or support state.

manual assembly, power, and modification safety boundary · official assembly and firmware guides · source cautions and optional modifications documented

The official guide warns that soldering irons are hot, emit fumes, and can be dangerous if misused, recommends ventilation or fume extraction, and warns that WS2812B LED plastic can melt. It also documents optional power-bank, lanyard, stand, sensor, and I2S modifications without supplying an event-wide electrical safety review, battery policy, enclosure specification, current budget, or support guarantee.

The catalogue records the public hands-on workflow while avoiding a claim that all configurations are safe, supplied, tested, supported, or appropriate for every builder.

scheduled workshop and post-event fulfillment boundary · official schedule, ANSSI listing, and public source tree · ten sessions and build documentation published; individual attendance and completed handoff unverified

Official leHACK and ANSSI pages schedule ten Badge Hackropole sessions, while the repository provides public build materials. The reviewed public sources do not publish a final session-completion report, attendee roster, kit count, finished-board count, individual receipt record, replacement policy, or post-event fulfillment account.

The compendium can preserve a concrete workshop artifact and buildable design without treating a schedule or a public repository as proof that every listed slot ran or that any specific person received and completed a badge.
