Touch-triggered audio and LED interaction
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.

public firmware interaction surface
The source initializes touch ADC support, reads PD2 through `ReadTouchPin`, starts audio after a threshold, and updates the source-declared D/F/I/U and display LED outputs from timer-driven code. This is source-level evidence of the intended interaction, not a claim that every physical unit behaves identically or that its touch sensitivity, sound volume, audio content, LED population, timing, accessibility, or reliability has been independently tested.

official maker/seller page
Maker-operated DEF CON 34 storefront page with the limited-presale context and a $20 OffensiveSAO card that describes touching Lintile's face, a "Don't Fuck It Up" cheer track, and continuous-play wording. The page's text does not label that card DFIU, so its exact DFIU mapping is used only together with the public Badgelife roster; page media do not state reusable-image rights.

public Badgelife self-submission roster
Public DEF CON 34 Badgelife response row from BigFuckingBadge / Hexum064 that names the DFIU SAO, calls it an SAO, gives a $20 price, describes the face-touch/chant interaction, and links the public hardware and code repositories. It is a submitter-provided pre-event association, not official DEF CON issuance, final sale/delivery proof, technical certification, or image-reuse permission.
Badge: DFIU SAO (DEF CON 34)
public firmware build configuration
Published `platformio.ini` defining the `ch32v` platform, `genericCH32V003F4U6` board target, and `ch32v003fun` framework. It documents a source-tree build target, not a complete flashing guide, a final production MCU marking, a signed firmware release, or a warranty-safe modification path.
Badge: DFIU SAO (DEF CON 34)
public firmware-source repository
Public Hexum064 firmware repository with PlatformIO configuration, include/source/library/test directories, audio and touch references, and code for the DFIU interaction. No README, release, or explicit root LICENSE/COPYING file was identified in the reviewed repository root; publication does not establish final production parity, build reproducibility, support, or permission to republish media.
Badge: DFIU SAO (DEF CON 34)
public hardware-source repository
Public Hexum064 hardware repository with a KiCad PCB and schematic, BOM and position CSVs, Gerbers, backups, and layout material. Repository visibility is an engineering trail, not proof of a final assembled revision, a complete production package, a fabrication outcome, safe operation, or an explicit license grant.
Badge: DFIU SAO (DEF CON 34)
public interaction implementation source
Published C source declaring the audio-enable/PWM path, PD2 touch pin, letter/display LED outputs, touch-ADC initialization, thresholded `ReadTouchPin` behavior, sampled `audio_dfiu` playback, and timer-driven LED update logic. Source code evidence does not determine exact final assembly, recorded-audio provenance, sound level, accessibility, safety, reliability, security, or end-user support.

Primary maker/seller source for the DEF CON 34 limited-presale setting and its $20 OffensiveSAO card about touching Lintile's face to trigger the "Don't Fuck It Up" cheer track. The card is textually unlabeled, so this source is paired with the submitter-provided DFIU roster row; it does not establish official DEF CON status, final stock, delivery, technical specification, endorsement, audio/image rights, or image reuse permission.

BigFuckingBadge / Hexum064 via public DEF CON 34 Badgelife response sheet · retrieved 2026-05-15
Primary public self-submission source that names the DFIU SAO, identifies BigFuckingBadge / Hexum064, gives a $20 price, states the Lintile-face/"Don't Fuck It Up" interaction, and links its hardware and firmware repositories. It establishes an intended independent BadgeLife association, not DEF CON organizer issuance, admission, completed manufacture/sale/handoff, testing, or image reuse rights.

Primary build-configuration source specifying the `ch32v` platform, `genericCH32V003F4U6` board, and `ch32v003fun` framework. It supports the firmware target claim but does not identify a final board configuration, programmer, flashing procedure, release artifact, source license, or production validation.

Primary implementation source for touch ADC initialization, PD2 touch reads, threshold-triggered `audio_start`, timer-driven sampled audio, and D/F/I/U plus display LED update outputs. It supports the described source behavior but not the exact public production audio, volume, mechanical touch surface, completed hardware build, functional reliability, accessibility, content licensing, or user-facing safety/support claims.

Primary public firmware-tree source for PlatformIO configuration and the code/include/source layout. The reviewed root did not visibly expose a README, release, or explicit LICENSE/COPYING file, so it is evidence of a public development trail rather than a final supported/open-source product release.

Primary public hardware-tree source for a DFIU-named KiCad PCB, KiCad schematic, BOM/position CSVs, Gerbers, backups, and layout material. The reviewed root did not visibly expose an explicit LICENSE/COPYING file; its contents do not by themselves prove final population, fabrication, safety, compliance, shipment, or a license grant.
