Wild West Hackin' Fest Deadwood 2025 E-Badge
Antisyphon-sponsored ESP32-S3 badge CTF
The Wild West Hackin' Fest Deadwood 2025 e-badge was the conference's electronic badge and badge CTF artifact. The official WWHF e-badge page identifies Antisyphon Training as the badge sponsor, Meta CTF as the scoreboard/challenge partner, multiple challenges solvable from badge behavior or firmware, and Ray Feltch, David Fletcher, and Rick Wisser as badge-team contacts.

SourceWhy It Mattered
It adds a current U.S. hacker-conference badge where official challenge infrastructure and a post-event attendee teardown both exist: the badge was not just swag, but an ESP32-S3 CTF target with LEDs, serial output, BLE surfaces, firmware extraction, and encoded challenge strings.
Hardware
The official e-badge page proves the electronic badge and challenge scope but does not list components. AlrikRr's post-event teardown describes a USD 40 badge with an ESP32-S3-WROOM-1, a 0.96 inch 128x64 I2C OLED-like display, TP4056 single-cell Li-ion/Li-poly charging, a battery of unknown capacity, USB-C serial access, and eight visible LEDs arranged as four top and four bottom challenge LEDs.
Software & Apps
WWHF says the badge CTF could be solved by observing badge functions or diving into firmware, with registration handled through Meta CTF at `mctf.io/wwhf25`. The teardown documents 115200-baud serial output, Base64 challenge strings, BLE-readable messages, SHA1 hash-cracking clues, ESP32-S3 flash extraction with esptool, partition-table analysis, Ghidra Xtensa analysis, and ROT13, ROT5, Bacon cipher, Base64, and Base32 puzzle strings.
Lore
The official event page anchors the October 8-10, 2025 Deadwood Mountain Grand conference, while the badge page was published before the event and updated shortly before the conference. The teardown preserves the lived badge-hacking sequence after the event and includes a practical warning that the TP4056 charger could get hot when the badge was used while plugged in over USB/serial.

Issues & Camp Impact
charger heat caveat
caution
The teardown warns that the TP4056 charger could get very hot when the badge was used while plugged in over USB/serial.
The record preserves a practical handling caveat without escalating it beyond the attendee report or claiming a formal recall/safety notice.

hardware-source boundary
note
The official WWHF page proves an electronic badge and badge CTF but does not publish a component list, schematic, BOM, firmware release, PCB files, or challenge-source archive; component-level details currently come from a post-event attendee teardown.
The catalogue records ESP32-S3, OLED, charger, LED, BLE, serial, and firmware-analysis details as teardown-backed rather than official board documentation.

missing rights-cleared image
note
No Wild West Hackin' Fest Deadwood 2025 E-Badge image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.
The United States record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
