Seeded artifacts
A source-backed French electronic attendee badge from Nuit du Hack 2011, preserved through an attendee report, badge photos, and linked reverse-engineering/programming tutorials.
A limited collector badge and hardware-hacking challenge from Nuit du Hack 2014, with public challenge rules, writeups, and a Virtualabs repository.
A limited NDH2K15 electronic collector badge kit sold through the official Nuit du Hack store, described as Arduino Micro-compatible, USB-compatible, easy to program or hack, and developed by Electrolab.
A French THcon 2026 official electronic badge documented by the official B.A.D.G.E. page as an ESP32-C6 board with a WiFi access point, an I2C OLED at address 0x3C, and two badge challenges built around a BLE padlock and a one-time-password flow, for the May 5-6, 2026 tenth edition in Toulouse.
Events
A French HackerzVoice security-conference edition with a public attendee report describing a 100% electronic badge and linked reverse-engineering tutorials by its designer.
The Fnord Edition of Nuit du Hack, whose collector badge was an assemble-and-hack hardware challenge for a Black Badge life pass.
The 2015 Nuit du Hack edition whose official store sold an Electrolab-developed Arduino Micro-compatible electronic badge kit limited to 200 units.
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.
Lifecycle
The official badge page documents a BLE padlock interaction as one of two badge challenges.
The official badge page documents a one-time-password flow as the second badge challenge.
The official badge page documents a WiFi access point branded Badge3000 as part of the ESP32-C6 badge interaction surface.
The Virtualabs repository preserves Python console tooling and serial interaction material for working with the badge challenge.
The official store lists USB/HID keyboard and mouse emulation as a supported hack path for the Arduino Micro-compatible kit.
The official challenge asked participants to assemble the collector badge, analyze its embedded secure system, and solve first for a Nuit du Hack Black Badge life pass.
The kit advertised a prototyping area and explicitly invited attendees to hack the hardware in wearable and other forms.
The attendee report links a designer-authored reverse-engineering guide and a second programming guide that used avrdude, avr-gcc, and C examples.
The 2016 report describes a Pimp My Badge workshop using the previous year's electronic badge and updating the standard library with additional examples.
The 2015 electronics workshop built a battery-powered Arduino pendant with an 8x8 LED matrix and noted that it could be combined with the 2015 electronic badge.
Operational history
The catalogue records the verified official badge surface without inventing component-level display, input, power, or design-archive details.
This was not necessarily a universal attendee badge; the page models it as a collector/challenge object rather than a default registration badge.
The page should not imply that every attendee automatically received this badge; it was a limited store item.
The source-backed facts remain available while the catalogue withholds imagery until original photos are cleared.
The French record remains source-backed and image-free rather than copying official site imagery, screenshots, social media, placeholders, or generated approximations.
Publish no image until licensing and attribution for an original badge photo are cleared.
Publish no image until licensing and attribution for an original badge photo are cleared.
The 2015 badge should be treated as a reusable workshop platform across the following edition, while the catalogue should not invent a distinct NDH 2016 badge without stronger sources.
The dossier remains useful for French badge history while avoiding unsupported chip and firmware claims.
