Lifecycle
Badge ecosystems keep moving after handout: apps, hexpansions, SAOs, antennas, cases, repair parts, firmware updates, and post-event hardware experiments.
The Basic Edition firmware was documented with CTF tasks started through serial terminal utilities, and the public CTF repository preserves eight post-event challenge write-up areas.
SourceThe Virtualabs repository preserves Python console tooling and serial interaction material for working with the badge challenge.
SourceThe official volunteer page lists welcoming participants, distributing badges and goodies, and orienting visitors among the conference rooms.
SourceThe badge challenge used six lanyards carrying Lewis Carroll Nyctograph symbols and Poe Gold Bug cipher material that translated into early-stage secret messages.
SourceOne sold-out $150 storefront option adds the separately-made Laser* Tag Badge DS from Dani.pink, which the maker says can be picked up alongside the Monorail badge. This records a bundled purchase/co-pickup statement, not shared hardware, firmware, manufacture, ownership, event affiliation, or a guarantee of either badge's delivery.
SourceNicolai Electronics presents Tanmatsu as a preassembled, out-of-the-box handheld derived from the Konsool open-design community hardware project.
SourceThe hardware README names an ESP32-C6, a 2.79-inch 142×428 colour IPS NV3007 display, LoRa hardware, and AHT30; the archive contains native KiCad project, schematic, and PCB material. This retains a high-level documented design surface without asserting a final BOM, populated revision, power path, antenna, test result, safety assessment, or final unit configuration.
SourceThe communicator add-on is documented as part of the 2024 badge ecosystem.
SourceThe teardown documents 115200-baud serial output, BLE-readable messages, hash clues, and firmware strings analyzed with Ghidra.
SourceThe README and changes document an RNode-oriented modem integration and Reticulum mesh context on the documented board. This is an archive-level capability statement only; the record does not state a frequency, configuration, deployment, coverage, legal authorization, field result, or operating procedure.
SourceThe curated Hackaday.io list preserved attendee-built cases, Atari and Apple-like emulators, games, music, QR generation, Morse code, Bluetooth chat, and plotter firmware hacks.
SourceThe thread clarifies that the forum badge was a separate extra badge for forum-member recognition, not a sticker or overlay for the official DEF CON badge.
SourceKonrad Beckmann's README-listed project used the RP2040 game badge as a video player and AM radio transmitter.
SourceThe 2023 data export includes event and community entries such as RFID Rocket, Minibadge Community Badge, LAN Party, Hardware Hacking, Fox Hunt, The Keep, and Hallway Talks.
SourceJens 'JWolf' Larsen's README-listed adventure game preserved the Game On badge as a homebrew handheld target.
SourcePieter Vander Vennet's README-listed Flappybirds project appears in the BornHack 2022 badge project list.

SourceHackaday documented thousands of custom DEF CON 25 hardware badges, a badge-maker meetup, and shared API work among makers, making the simple official badge historically important by contrast.
SourceCommunity ROM work showed the badge running custom Game Boy ROM code and controlling all nine LEDs beyond the default controls.
SourceThe r4venOS community firmware replaces the Pacman firmware with a WiFi scanner, evil-twin detector, deauth, and crypto utility toolkit on the same ESP32 hardware.
SourceThe community Meshtastic guide maps the badge to a PlatformIO ekoBadge environment with RFM95, OLED, three NeoPixels, keyboard buttons, and speaker pins.
SourceThe guide lists AppSec, Circuit Assembly, Hardware Hacking, Healthcare, HomeLabs, IoT, Lockpicking, RFID/NFC, Scavenger Hunt, SMD Challenge, and Learn 2 Solder style badges acquired through community areas, booths, challenges, or presentations.
SourceThe official page documents Red Team Community, RFID/NFC, Hardware Community, Lock Picking, Tin Foil Hat Talks, and related MiniBadges with acquisition tied to community events or interaction.
SourceThe BIC Pick page says the badge can be spotted on village volunteers, leaders, and supporters throughout the con.
SourceA community Arduino nofrendo port ran NES games on the Fri3D 2022 badge with display output, buzzer audio, ROM loading from SPIFFS, and a documented START-button workaround.
SourceHack Your Lives' current listing is sold out and says each assembled-badge order includes an additional blank PCB offered for in-person DEF CON 2026 pickup; uncollected blanks would ship with the assembled order. It says paid orders will be assembled and shipped by September 30. These seller statements do not establish paid-order count, completed assembly, shipment, delivery, pickup, replacement, refund, or that every order receives an identical final unit.
SourceThe same project archive includes a backpack-mounted open access point and four-matrix scoreboard that counted unique connecting clients during the conference.
SourceElectronic Cats' companion repository calls itself official Pwnterrey 2026 firmware and retains ESP32-C5 headless Marauder-derived source, documentation, and build material. Its root MIT text credits Just Call Me Koko; this record does not equate that upstream text or visible build artifacts with a final signed event binary, production configuration, safety review, or generalized authorization to operate wireless functions.
SourceThe organizer repository documents a separate through-hole soldering-workshop board: a TLC555P and CD4017BE LED chaser with four LEDs, a 500k trimmer, and CR2032 power, cut to Alice, White Rabbit, and looking-glass artwork.
SourceOfficial attachment pages preserve first, second, and third-place ACFT badge-art variants for the 2021 set.
SourceThe ICFT player OP2 attachment page preserves a distinct ICFT player badge-art variant in the 2021 set.
SourceThe official home identifies Time Travel: Capture the Flag as the June 6 event's hands-on CTF context. It does not say the fun badge runs, unlocks, contains, or is required for the CTF.
SourceBeelog's official project page says it designed, manufactured, and developed 418 electronic badges for MNCERT CC as a custom order. The companion archive identifies MNSEC 2025 and says the work was completed, but neither source publishes ticket eligibility, recipient identities, handoff records, or evidence that all conference attendees received a badge.
SourcePacket Hacking Village's official programme lists the completed Saturday Friend or Foe presentation at DEF CON 34. It links the documented project to a completed village programme but does not say the village made, distributed, sponsored, sold, or endorsed badges, or that attendees received one.
SourceThe public DC-SG-1 badge talk describes the electronic hacker badge as given to ticket holders for entry to DEF CON Singapore.
SourceThe official Badge Project page says every 2026 attendee received a bare PCB with no components.
SourceThe `Understanding & Making Pcb Art` session placed TwinkleTwinkie's PCB-art practice in the DEF CON 27 Hardware Hacking Village programme.

SourceInfoconDB preserves Badge Intro context for the 2017 event, tying the artifact to attendee-facing badge material.
SourceInfoconDB preserves a Badge Intro session on the RVAsec 2021 schedule.
SourceThe official agenda says workshops are exclusive to BSides Porto 2026 badge holders and that registration alone does not grant entry.
SourceThe listing names a configuration PWA and USB-C updating. The firmware README describes one RPC registry exposed through web, USB serial, and BLE, including settings, saved messages/locations, OTA update, and system functions. The companion PWA repository is public but unlicensed and does not establish a deployed service, credential, or data-retention model.
SourceThe Compass wrap-up says attendees configured the badge by connecting to badge WiFi and entering a username in a web interface.
