Independent IR game/TV-control badge and Sheriff SAO combo listed for DEF CON 33
BigTaro's Tindie page calls Gunslinger-B-Gone an electronic badge with laser tag, a TV-B-Gone, a CTF, and an included Sheriff SAO; the page shows $100 and says it has been sold out since September 13, 2025. A separate Hacker Couture DEFCON 33 Product List independently lists a Gunslinger-B-Gone Badge by BigTaro at $140 and describes laser-tag play with the Sheriff SAO, making friends' badges light up, pointing an IR blast at a TV to power it down, CTF challenges, bling modes, Drinking Roulette, and a fully-programmable claim. BigTaro's Sheriff guide identifies the Sheriff companion as an RP2040-chip board, documents a CR2032 or LIR2032 battery holder with magnet and sticky pad, an independent battery switch, a standalone/wearable configuration, and an optional soldered SAO connection to the Gunslinger with the notch side up. These sources establish a real independent electronic-badge combo and a 2025 DEF CON vendor-list association, not a BadgeLife drop, official DEF CON issue, admission credential, complete IR or electrical specification, confirmed vendor handoff, firmware source release, or reusable-image rights.

Completed 418-unit, three-variant MNCERT/CC electronic-badge collection
A completed MNSEC 2025 electronic-badge collection commissioned by MNCERT/CC and documented by Beelog Technologies. Beelog's public project page states that it designed, manufactured, and developed 418 electronic badges for MNCERT/CC; the public MNSEC2025BADGE archive identifies the order with the September cybersecurity conference, says three badge types were completed, and preserves Gerber, schematic, firmware, example-code, and supporting-material directories. The sources do not establish attendee allocation, a per-unit delivery record, final unit-by-unit configuration, safety validation, or reusable image provenance.

Independent ATtiny1616 analog-input puzzle badge with a scheduled DC33 drop and current DC34 continuity
Hak4Kidz Lab's Tindie listing calls Masonic33 a cryptic, interactive badge for puzzle lovers, hackers, and DEF CON attendees. It says two 10 kΩ potentiometers control an ATtiny1616-based board with eleven independently controlled LEDs; players tune analog inputs to unlock a hidden LED sequence and solve four puzzles. The listing also names a UPDI-compatible one-wire programming interface, 4.5 V AAA-battery input with batteries included, a 4.25-inch black-solder-mask/white-silkscreen PCB, custom VHS-style box, patches, lanyard, and stickers. A recovered public DEF CON 33 schedule records a 10:30-10:59 PDT BadgeLife Community Masonic33 Badge drop credited to Heal-Hak4Kidz, while the Hacker Couture DEFCON 33 product list separately shows the Masonic33 Badge at $125. Badge.Life's live DC34 Village Schedule additionally lists Masonic33 Badge — heal at 10:30 AM on Friday August 7 and 11:00 AM on Saturday August 8, 2026, without naming a changed board or revision. These sources establish a real independent 2025 puzzle badge with planned 2026 continuity, not official DEF CON issuance, admission, a confirmed completed drop, a separate DC34 artifact, a complete circuit/firmware archive, a connection to any fraternal organization, or reusable-image rights.
Unofficial badgelife robot-fighting badge set
NilbinSec's Hack 'Em Crack 'Em Robots was a DEF CON 33 badgelife release announced in the DEF CON #Badge Life forum, sold as a limited full-size badge set through RENXCHANGE, and listed in the DC33 community schedule as a badge drop.

Hackable electronic CTF badge with a source-depth caveat
A conservative PWNEDCR 0x08 record: a named post-event account says the October 18-19, 2025 San José conference used a hackable electronic badge as part of its CTF, with hidden Easter eggs and challenges. It supports the reality of a physical electronic badge but publishes no component, firmware, maker, production, or reusable-image documentation.
Large physical ATM attack-surface simulation artifact
A preserved DEF CON 33 programme describes Payment Village's Vulnerable ATM Badge as the conference's largest badge that year: a physical form factor attendees could carry with two hands, built to simulate ATM attack surfaces. Payment Village's own DEF CON 33 page confirms the village/event context, while its 2026 schedule still lists an Introduction to the Vulnerable ATM Badge. The recovered sources establish the named physical educational artifact, not its electronics, a reusable current build, or a 2026 reissue.
Battery-less ZBD shelf-label badge with per-attendee firmware images
PhreakNIC 26's official electronic badge reused dead-battery ZBD 55c-RB electronic shelf labels as 3D-printed pager-styled badges with static 240x96 one-bit displays, QR-code-backed attendee customization, and on-site reflashing.

First electronic badge in summit history
Red Team Summit's official history identifies the March 11-12, 2025 Redmond event as the first Red Team Summit with an electronic badge. The same historical record gives 194 attendees, 61 organizations, and 108 CFP submissions, but does not describe the badge's physical form, technology, maker, or recipient scope.
Independent 25-slot Simple Add-On host badge; later DEF CON 34 roster continuity
Coruscant Ventures' official SAO Many SAOs Badge page identifies the object as a DEFCON 33 product, presents it as a 25-design Simple Add-On display platform, and says its outer LEDs require the separate SmartAO SAO. The maker's public technical README says the badge has two pre-installed 18650 batteries, USB and barrel-connector power/charging paths, up to 25 SAO slots, and an approximately 300 mA at 3.3 V total SAO budget when using charged batteries. A July 2026 public DEF CON 34 Badgelife response marks SaO MANY SAOs as Update to Existing, gives an $80 price and Venmo acquisition note, and repeats 25 SAO slots plus a 360 by 360 mm size. The current roster does not identify a changed board or new revision, so this is one independently documented DEF CON 33 host badge with a later availability/continuity record, not a duplicate DEF CON 34 artifact, official credential, completed sale, confirmed delivery, or rights-cleared image.
Independent electronic badge and Pirate Flag SAO bundle with a scheduled DC33 BadgeLife drop
BigTaro's Tindie listing calls this the Submarine Badge & Pirate SAO and describes a $150 Defcon-pickup preorder. It frames the electronic artifact as an interactive underwater world with CTF package deliveries in DEF-SEA, pirate battles, underwater cults, Atlantis, hardware/software puzzles, and soldering challenges. The source says it has a super-bright round display, more than six buttons, one SAO port, exposed extra GPIO, a fully-programmable claim, an exclusive Pirate Flag SAO bundle, stickers, and an interaction with Gunslinger-B-Gone. BigTaro's own Submarine page supplies a live dashboard-like maker surface, and the DEF CON 33 Creator Events List independently schedules a Friday BadgeLife Community Table 1 drop naming Submarine alongside FrogStar and FightDystopia. These sources establish a real independent electronic-badge bundle and a scheduled 2025 event activity, not an official DEF CON credential, confirmed attendance or handout outcome, production count, electrical design, firmware source release, or reusable-image rights.
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.

Maker-stated DEF CON 33 multicolor-LED Simple Add-On; 2026 leftover pickup only
coryallegory's live Uberflux listing calls this the Vibe Coder Dog SAO, says Science Dog is now Coder Dog, and says the artifact was created for DEFCON 33. The same current listing says a few leftover units are available as a 2026 pre-order for pickup at DEF CON 34 or BSidesLV in Las Vegas. Its August 4, 2026 snapshot lists $15, five sold, and zero remaining, with a free Saturday August 8 BadgeLife Village pickup label. The maker says the unit is fully assembled, has a standard 2 by 3 SAO header, and uses cycling multicolor LEDs to light its keyboard with AI magic. This is source-backed evidence for an independent DEF CON 33-associated LED Simple Add-On, not proof of the original 2025 distribution, a specific controller or actual AI behavior, final 2026 pickup, DEF CON organizer affiliation, conference admission, or reusable-image rights.
Capable hardware, difficult camp history
The Dutch 2025 camp badge mixed ambitious hardware with late distribution, LoRa caveats, battery-safety controversy, and a documented pre-event team conflict.
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.
