THcon 2026

The May 5-6, 2026 tenth Toulouse Hacking Convention whose official B.A.D.G.E. page documents an ESP32-C6 electronic badge with a WiFi access point, I2C OLED, and BLE padlock and one-time-password challenges.

THcon 2026 Badge

The official THcon 2026 B.A.D.G.E. page documents an ESP32-C6 electronic badge with the Badge3000 WiFi access point, an I2C OLED at address 0x3C, and BLE padlock and one-time-password challenges for the May 5-6 tenth edition in Toulouse. A May 13 first-hand attendee teardown identifies the distributed board as an ESP32-C6-WROOM-1 build with an SSD1306 OLED, WS2812 RGB LED, ATC24C04 EEPROM, SAO connector, single-cell battery/TP4056 charging path, and USB-C CH340C serial bridge; it also documents the delivered firmware's BLE color-command propagation behavior.

THcon 2026 Badge first-hand firmware analysis

badge-to-badge interaction

BLE color-propagation behavior

The attendee's analysis reports that the delivered firmware observes compatible BLE advertisements, changes the RGB LED from received color values, and relays them with loop avoidance. This documents an interaction behavior without publishing packet construction, operating instructions, production-firmware identity, range, compliance, or final event deployment claims.

Compatibility: THcon 2026 Badge

THcon 2026 Badge first-hand artifact analysis

hardware documentation

Artifact-level board component inventory

An attendee teardown identifies the distributed board's ESP32-C6-WROOM-1, SSD1306 OLED, WS2812 RGB LED, ATC24C04 EEPROM, SAO connector, single-cell battery/TP4056 path, and USB-C CH340C serial bridge. It does not establish a final production revision, pinout, electrical characterization, or official design archive.

THcon 2026 Badge note

hardware-detail and archive gap · official and first-hand source · needs official source-archive recovery

The official page and a first-hand teardown now identify the ESP32-C6-WROOM-1, SSD1306 OLED, WS2812 LED, ATC24C04 EEPROM, SAO connector, single-cell/TP4056 power path, and CH340C bridge. They still do not establish OLED resolution, buttons, SAO pinout, battery capacity/protection, charger settings, board revision, schematic, BOM, Gerbers, official firmware source, canonical binary, release, or license.

The catalogue can distinguish observed artifact details from the unrecovered official archive while avoiding unsupported production, electrical-safety, design-file, firmware, or reuse claims.

THcon 2026 Badge note

missing rights-cleared image · local project policy · needs licensed original replacement

No THcon 2026 badge image is published because neither the official pages nor the first-hand Virtualabs teardown pairs a selected original badge photo or upstream render with the complete reusable source URL, publication-compatible permission basis, attribution, and processing record. The teardown's CC BY-NC-SA content notice is not treated as a clear public-image reuse basis for this catalog.

The French record remains source-backed and image-free rather than copying official site imagery, the teardown photo, screenshots, social media, placeholders, or generated approximations.
