ESP32 touch-wheel badge with TFT, audio, LEDs, and games
The THOTCON 0xD badge was a Fourfold-built electronic conference badge for the May 30-31, 2025 Chicago event, documented as a 2,000-unit ESP32 touch-wheel badge with ST7789 TFT display, buzzer, six LEDs, LiPo power, add-on header, games, visual effects, and challenge hooks.
BTV Camera Badge (DEF CON 34 Fundraiser)
Pre-event BTV fundraiser for a DC32-origin ESP32 camera badge
Blue Team Village at DEF CON's Eventbrite offer schedules the BTV Camera Badge as a DEF CON 34 fundraiser for August 7-9, 2026 at the Las Vegas Convention Center West Hall, with in-person village pickup only. It offers an assembled badge and lanyard for $120 or an intermediate-to-advanced soldering kit for $60. The listing says the badge does not take photos; instead, in an appropriate mode, its camera-lens display shows when deauthentication packets are being sent or Flipper Zeros are nearby, and says its brain is an ESP32 board capable of custom software. BTV's public MIT `btv_dc32_badge` archive explicitly describes the artifact as a DEF CON 32 indie badge and preserves its Arduino source, KiCad project, Gerbers, CAD/fabrication files, parts list, and assembly guide. This is a current source-backed fundraiser for a documented DC32-origin design, not evidence of a newly engineered DEF CON 34 hardware revision, completed pickup, final 2026 firmware, radio-detection performance, electrical safety, conference admission, or reusable-image rights.
CONFidence 2026 ConfiBadge
ESP32-C6 hackable badge and Badge Hub for CONFidence
An official electronic badge for CONFidence 2026 in Krakow, documented as a hackable ESP32-C6 platform with OLED display, I2S audio amplifier, six navigation buttons, rechargeable LiPo power, firmware challenges, an 8-pin expansion port, and a live Badge Hub for MicroPython packages and community mods.
DEF CON 34 Silent Disco Badge
Maker-published physical silent-disco badge; organizer role and handoff unverified
LastZactionHero's public repository is titled DEF CON Silent Disco Badge and documents a wearable electronic badge that plays local DJ mixes, drives a music-linked light show, and syncs badge-to-badge over infrared. Its August 4 maintainer update says the boards were fabricated, assembled, and playing music, and that every badge's QR silkscreen points to the repository. The public archive contains KiCad design and fabrication material, firmware, and a MIT license, sufficient to record a distinct maker-published physical DEF CON 34-associated artifact. No reviewed DEF CON, venue, silent-disco organizer, sales, or handoff source establishes official issuance, a run size, recipient allocation, or completed event distribution.
Gothcon 2026 Blinky Badge
Pre-event ESP32-C3 bat-shaped LED party-fundraiser badge
Gothcon's official badge store describes a custom bat-shaped PCB LED badge for the free Gothcon dance party at DEF CON 34. The $80 fundraiser package names 44 independently controlled RGB LEDs, a 2,000 mAh Li-Po battery, USB-C recharging with overcharge protection, a removable laser-etched acrylic shield, a custom lanyard, and an ESP32-C3 with 4 MB flash. The public `claviger/gothcon-firmware` repository adds MicroPython firmware, KiCad schematic/PCB/Gerber material, GPIO mapping, pattern/palette controls, and ESP-NOW badge-to-badge contagion. The store explicitly says its SAO connectors are mirrored and not functional with a standard SAO. Pre-orders are closed and the store says badges will be sold at DEF CON; this remains a pre-event party-fundraiser record, not proof of final sales, delivery, party outcome, or official DEF CON credential status.
HRV SSTV Badge (DEF CON 34)
Maker-published planned SSTV badge project for HRV/DEF CON 34; physical unit unverified
The public `livitup/hrv-sstv-badge` repository describes itself as building an SSTV #badgelife badge for HRV at DEFCON 34. Its commit-pinned source contains a project README, native KiCad board files, and a status document dated March 22, 2026 that still records design and prototype milestones rather than a shipped unit. Ham Radio Village's own page independently confirms its DEF CON 34 event in Las Vegas on August 6-9, 2026, but does not identify or endorse this project. The sources therefore support a publicly documented planned independent electronic-badge project associated with HRV/DEF CON 34, not an HRV- or DEF CON-issued artifact, ticket benefit, access credential, completed unit, allocation, delivery, or rights-cleared image.
Hacker Pager (DEF CON 34 Revision)
Maker-announced independent Hacker Pager revision for DEF CON 34; handoff outcome unverified
A first-hand Exploitee.rs announcement says the team is bringing a new Hacker Pager revision to DEF CON 34, with planned online availability and BadgeLife Village pickup. Its official project site documents an ESP32-S3, Semtech SX1262 LoRa radio, monochrome LCD, microSD, USB-C, rechargeable LiPo power, buttons, speaker, vibration motor, LEDs, and open design sources; its current update page labels firmware 2.7.26.pager as DEF CON 34. Public electronics and case repositories publish KiCad/BOM and mechanical source material under CERN-OHL-S-2.0. This is sufficient evidence for a distinct, independently sold pre-event BadgeLife artifact associated with DEF CON 34, not evidence of DEF CON issuance, authorization, admission, a completed sale, pickup, delivery, final production configuration, or rights-cleared image.
Helgatchi Badge (DEF CON 34)
Independent ESP32-S3 BLE and Wi-Fi scanner badge offered for DEF CON 34
DC801's live Helgatchi product page identifies a $120 portable, rechargeable BLE-beacon and Wi-Fi-access-point scanner/hunter with configurable alerts. It names a XIAO ESP32-S3, 8 MB flash, a 400 mAh 3.7 V LiPo, 1.69-inch 240 by 280 Waveshare LCD, six RGB LEDs, vibration motor, and external SMA-RP 2.4 GHz antenna path. Pips801's public repository contains separate hardware and firmware/UI trees, while the public DEF CON 34 Badgelife response identifies DC801 + 801 Labs' Helgatchi as a new badge associated with the August event. The listing remains an independent seller artifact with planned July pickup/shipping terms—not official DEF CON issuance, a Human badge, admission, confirmed recipient delivery, a fully audited detection device, an open-source license, or a rights-cleared image.
RootedCON 2026 Pacman Badge
Spanish ESP32 PACMAN CTF badge with project-builder and community-reversal evidence
RootedCON 2026's PACMAN-themed attendee CTF badge is documented by both community reversals and a first-hand TechFrontiers project-builder write-up. David Melendez Cano reports original colored Ghost boards that attendees could choose, an ESP32-WROOM-32 platform, ESP-NOW game-server interaction, per-badge NVS identity/key material, and digitally signed questions and answers. Community reversals independently identify an ESP32-D0WD-V3, 1.77-inch ST7735 128x160 display, directional controls, and native quiz-server CTF protocol for the March 5-7 sixteenth edition at Kinepolis Madrid.
Shitty Kitty V2 (DEF CON 34)
Pre-event sold-out RP2040 dual-SAO BadgeLife restock
Uberflux lists Shitty Kitty V2 under the `lipo` maker handle and Uberfoo Heavy Industries, with DEF CON 34 as its only listed drop. At this August 3 source pass, the $75 listing is marked OUT with zero remaining and 15 sold, and says new stock is available for DEF CON 34 pickup. Its maker-published description names dual 0.96-inch color IPS screens, an RP2040 platform, two fully connected 1.69bis SAO ports, USB-C, LiPo power/charging components, five user buttons, a boot button, and SkittyOS features. It also announces new firmware with graphics and puzzles, but provides no release link. This is a documented pre-event restock listing, not proof of final pickup, a completed firmware release, a reproduced engineering archive, or an official DEF CON admission credential.
Station 562 Badge (DEF CON 34)
Pre-event independent BLE number-station puzzle badge for DEF CON 34
Station 562 is a source-conservative independent DEF CON 34 badge record from its public maker announcement. The project owner describes a proximity-controlled badge with a BLE number-station puzzle, red-versus-blue proximity game, autonomous social/dance mode, expressive BLE MIDI instrument, tamper-evident mode, Setup menu, and optional hardware CTF. In follow-up comments, the maker reports about 55 units made so far, signed firmware with a distinct key pair per badge, a constrained giveaway/sale plan, and RGB blank boards that omit the OLED, LiPo, and ESP32 module. No public repository, schematic, firmware release, final availability ledger, or reusable-image permission was recovered.
Wordweaving Badge (DEF CON 34)
Pre-event RP2350 CTF-adventure BadgeLife badge for DEF CON 34
BigTaro's own Wordweaving Badge project page and live Uberflux listing describe an independent DEF CON 34 top-down adventure / CTF badge. The current maker payload shows a $120 100-unit presale with 41 sold, DC34 pickup, and post-con shipping; it also says the badge would be $140 at the maker-described Hacker Warehouse booth during the conference. The maker describes an RP2350 with 4 MB flash, 16 RGB addressable LEDs, a 128×128 grayscale display, rechargeable LiPo via USB-C, and a fully addressable SAO port. It publishes game, CTF, multiplayer, word-building, and optional-component claims, but says hardware documentation and a stub firmware will only be provided after the conference. The project page says 30-plus CTF puzzles while the live listing says 35-plus, so the record preserves a broad maker-described challenge surface rather than resolving the discrepancy. This is a source-backed pre-event independent badge, not proof of final hardware/firmware, shipment or pickup, game availability, CTF completion, venue authorization, DEF CON affiliation, conference admission, or reusable-image rights.
