Lifecycle
Badge ecosystems keep moving after handout: apps, hexpansions, SAOs, antennas, cases, repair parts, firmware updates, and post-event hardware experiments.
The public Speedometer SAO firmware repository is MIT-licensed and says it includes CTF problem and notes material built on a display library.
SourceThe official LCA2022 Rockling session documented the Rockling FPGA audio processor as part of the hardware kit and SAO talk track.
SourceThe official LCA2022 SAO session described two shipped SAOs in the hardware kit, including Theremin and Party Button add-ons.
SourceCall Center Village's official shop describes a $5 pickup-only Solder-It-Yourself Telephone Booth SAO Kit for the DEF CON 34 badge. Its current public Badgelife roster row separately lists a $5 kit and $10 pre-soldered option. These source statements establish offered configurations and planned event context, not final inventory, payment, assembly, pickup, shipment, delivery, refund, replacement, or support outcome.
SourceA separate Pfarrside Creations listing offers the badge with two SAOs for $140. The source establishes the optional bundle but does not identify the SAOs' electronic design, pinout, compatibility, software, or final allocation.
SourceThe ToF SAO add-on provides a VL53L7CH 8x8 multizone sensor, eight addressable RGB LEDs, I2C access at 0x52, a Class I 940 nm laser, and an official MicroPythonOS app example.
SourceThe official Join Us page says attendees had to secure a badge ahead of time and that BSidesLV would no longer accept walk-ins for the conference.
Sourcedratini0's legacy adapter connects Tildagon to SAO, TiDAL, and QW/ST-style expansion traditions, showing that add-ons also serve compatibility and reuse.
SourceThe hardware list includes one 1.69bis SAO port plus conductive pads, 3.5 mm lead, elastic band, lube, custom lanyard, spare batteries, and battery clip.
SourceThe official DC34 SAO specification documents 3.0 V VDD, 100 mA tested total supply across both SAOs, GPIO pins, I2C devices at 0x3C and 0x19, and mirrored unkeyed 6-pin SAO headers.
SourceThe badge documentation identifies I2C expansion configured as DEF CON SAO plus USB terminal access for I2C and SAO sensor interfacing.
SourceThe badge includes an SAO connector that supports I2C, UART, CAN Bus, and more; the DC33 release explicitly adds Aerospace Village DC33 SAO support.
SourceThe README lists a Shitty Addon connector, making the badge compatible with the wider SAO-style add-on ecosystem.
SourceArea41's official participation notice asks attendees who have a Shitty Add-On for a badge to bring it along.
SourceThe 2022 hardware tree includes multiple SAO directories, including Ubisoft, numbered SAO revisions, BOMs, Gerbers, assembly exports, and board-source material.
SourceThe MiniBadge standard defines I2C read/write initiation, button, text, score-update, and brightness messages, while warning that microcontrollers need to track state across repeated starts and stops.
SourceThe minibadge notes define I2C address coordination plus polling, button, text, pixel, timed-pixel, custom-data, score-update, and brightness-change messages.
SourceThe CHV SAO spec provides 3.3 V and ground while replacing normal SAO I2C with CAN TX and CAN RX for vehicle-network add-ons.
SourceThe public MiniBadge standard supplies the shared connector and I2C protocol context for SAINTCON MiniBadges, while this 2020 record keeps per-board behavior limited to recovered source evidence.
SourceThe public MiniBadge standard supplies the shared connector and I2C protocol context for SAINTCON MiniBadges, while this record keeps per-board firmware claims limited to recovered 2021 evidence.
SourceThe public MiniBadge standard supplies the shared connector and I2C protocol context for SAINTCON MiniBadges, but this record does not claim every 2023 entry implemented active I2C behavior.
SourceThe public MiniBadge standard documents +VBATT, 3V3, GND, SDA, SCL, CLK, PROG, and NC pin guidance, including +VBATT voltage caution and do-not-connect rules for reserved pins.
SourcePOC Security's official update trail described a Zer0Con2025 Entry badge with 100 available seats.
SourcePOC Security's official update trail described a Zer0Con 2024 Entry badge with 120 available seats.
SourcePOC Security's official update trail described Zer0Con2026 registration as limited to 120 seats.
SourceThe official 2026 activities page says attendees must present a BSidesKC badge for entry to the afterparty. It does not say whether that means a paper/card credential, lanyard, wristband, QR/barcode, RFID/NFC credential, or the distinct 2025 electronic hardware.
SourceThe official ticketing page calls the Participant ticket general admission to the conference, and the registration page says badges are required for entry. Training Ground listings say a Participant Badge is required separately for those classes. These access descriptions do not establish material construction, electronic behavior, individual handoff, or transfer rules for every badge.
SourceThe Roanoke InfoSec Exchange Inc ticket listing offers General Admission w/Badge and says the ticket includes a T-shirt, badge, and lunch.
SourceThe CFP provides one paper-badge guest admission for a selected speaker and says a guest who wants an electronic badge must purchase a ticket.
SourceThe official registration pages say the issued badge gave access to all talks and workshops.
SourceThe official first-timer guide says students should bring valid student ID to registration and do not need to preregister.
SourceThe wiki preserves alternative software links for Tetris Sound Track, TV-Bunny, and Ethersex, showing the badge as a small AVR software target beyond the default firmware.
SourceThe Safe Mode badge was a real cassette tape in a jewel case, with side A/B markings, label art, and audio content that formed part of the challenge.
SourceThe assembly guide documents a 555 timer, photoresistor, capacitor, resistors, LED, AAA battery holder, and wiring; testing confirms the LED blink speed changes with light exposure.
SourceThe official badge was a playable vinyl record, making audio playback and record inspection part of the badge-hacking surface instead of firmware or active electronics.
SourceThe radio badge used RF gain control, a small transistor amp, mono audio sent to both headphone channels, and a hackable AM tuner path.
SourceBuilders could adjust the potentiometer to control how dark it needed to be before the badge lights turned on.
SourceThe early project post says the maker intends to do drops and make receiving a badge part of the experience; it also says a second variant is necessary for the interaction. It does not publish quantities, price, sales channel, dates, selection method, pickup or shipping terms, allocation, recipient list, completed drop, or final count of variants.
SourceThe Team says that after the paid cap is reached, distribution moves to random giveaways during the events. It does not identify giveaway quantity, timing, eligibility, selection method, organizer, physical allocation, handoff site, recipient list, or completed result.
SourceThe repository says winners of the 2026 Beverage Chilling Contraption Contest receive copies while stock lasts, and BCCC's official page locates the contest at DEF CON 34. This does not prove award recipients, winner quantity, qualification rules beyond the contest page, stock allocation, event outcome, or that the marketplace presale and winner copies are the same final unit run.
SourceThe storefront says each badge unlocks a live hacking challenge and frames progression as completing stages to climb a scoreboard. No reviewed source identifies challenge rules, format, tooling, endpoints, account model, scoring method, prize, operational schedule, data collection, accessibility, or a post-event archive; no software is inferred to run on the physical artifact.
SourceMatt Aragon announced two custom-built interactive NaClCON experiences: an NFC Scavenger Hunt Pieces of Eight and a Pirates vs British Navy NFC social-networking game. The announcement does not identify which physical event artifact participated in either experience.
SourceThe checkout lists Linq 3535 / Circle Bar pickup on Wednesday August 5 and Thursday August 6 from 7–10 PM PT and says there is no shipping. It says a receipt and offline QR claim code are sent after checkout; the Team says a badge must be collected at a meetup or by separately arranging DEF CON handoff, and the QR may be given to someone else. Those terms do not confirm venue access, checkout completion, code delivery, identity verification, handoff, or redemption outcome.
SourceThe organizer announced green attendee badges and purple sponsor/speaker versions. No reviewed post-event source publishes final colors, populations, quantities, eligibility records, or completed delivery for either variant.
SourceThe author says that most listed capability categories will not be ready out of the box and that only LED colour/brightness adjustment, a hidden software CTF or scavenger hunt, and NFC read/write are available on DEF CON day 1. That is an announced capability boundary, not a public firmware release, working demonstration, final event outcome, or guarantee of feature availability for every unit.
SourceAttendees could append JavaScript apps to `Badge.apps`, add LED patterns, upload code over BLE, and persist extensions in `.boot0` through `.boot3` storage files.
SourceThe getting-started and software pages link the Bangle.js App Loader and app repository as the public app-distribution surface for the watch.
SourceThe MK4 wiki documents installing apps directly on badge through the Badge Store app: choose Install, pick a category/app, save it, then restart back to the launcher.
