Lifecycle
Badge ecosystems keep moving after handout: apps, hexpansions, SAOs, antennas, cases, repair parts, firmware updates, and post-event hardware experiments.
The ticket page lists Basecamp ($300), Camp Muir ($500), and Columbia Crest ($1,000) under its 2026 patron section. It does not explicitly map the Special badge to one tier rather than another or document individual purchase and collection outcomes.
SourceThe FAQ asks visitors to bring a reusable lanyard or donate lanyards so the event can reduce waste while still issuing wearable badges.
SourceThe module guide documents a CC1101 SPI radio option for 315, 433, 868, or 915 MHz matching-network variants, powered through the peripheral rail.
SourceThe module guide documents an optional NS4168 I2S amplifier and SPH0641 PDM microphone sound module on the side-port hardware.
SourceNullcon Goa 2014 scheduled a dedicated Hardware Badge 101 session about the badge design, uses, idea evolution, and production problems.
Sourcedistinctm1nd's public archive contains matching badge documentation, KiCad PCB/schematic files, and a Meshtastic-derived source tree. The event does not directly link it, so it supports hardware and firmware discovery without proving final production or deployed software.
SourceThe DC32 repository publishes Arduino sketches, setup/compile/upload scripts, KiCad project files, Gerbers, CAD/fabrication material, a parts list, and assembly instructions under an MIT repository license. Its documentation also notes a then-precompiled CTF library, and no reviewed source establishes that every current fundraiser unit ships a specific repository commit or complete CTF source.
SourceDEF CON's August 7, 2025 news notice says attendees in the cash line were receiving paper badges because the main badge shipment was delayed.
SourceMake It Hackin publishes one STL intended to be printed twice as a two-piece capture ring that lets a wearer suspend the official DC34 badge at different rotations, using user-supplied M3 hardware or zip ties and a dual-clip lanyard. The maker says its geometry was photogrammetrically derived and is not an official DEF CON drawing; this is a design file, not a shipped, tested, or DEF CON-approved accessory.
SourceA maker writeup documents a simple BSides Ballarat 2026 SAO board with a six-pin pass-through connector and a WS2812B addressable RGB LED driven from pin 5.
SourceUberflux maker `bud-lightbeer` lists a $4 180-degree SAO adapter for the DEF CON 34 ports, which the maker describes as upside-down relative to the intended SAO 2.0 orientation. The listing says the adapter does not change the badge's 3.0 V supply and warns complex SAOs may not tolerate it; its current marketplace snapshot shows 593 sold, seven remaining, and Friday/Saturday Badge Life Booth pickup. This is a third-party compatibility product, not an official finding of a port defect or a universal compatibility guarantee.
SourceMainak Sarkar's Glyph project is a public companion app for the described Blinky 2350 and references battery, button, and case-light state. It is not represented as official Workday software, preinstalled content, an attendee-wide deployment, or the event's base firmware.
SourcePiia Alavesa's public CyberSlayer app targets the Disobey 2025/2026 board with a ten-zone cybersecurity combat game, NeoPixel progress and combat feedback, and documented installation via mpremote or the official development-firmware loader.
SourceMarx314's public post-event source implements custom NFC-to-webhook behavior with Wi-Fi setup and display/no-display builds. It is replacement firmware for an observed badge configuration, not NorthSec's factory firmware or Apache-2.0 source release.
SourceThe Rust repository documents badge examples including Breakout, Skyroads, Snake, Space Shooter, demoscene, shader, vector demo, display tests, LED bars, microphone, name-tag, scrolling, vibration, and async task-switch examples.
SourceThe MIT-licensed disobey2026badge crate and repository expose Rust APIs for the ST7789 display, nine GPIO buttons, WS2812 LEDs, display backlight, and vibration motor.
SourceThe listing says a standard USB wall brick or portable battery pack can power the Power Back, that an SAO totem can run multiple SAOs, and that it runs three #NOICE or Not Just a Crosswalk SAOs where a regular CR2032 does not have enough power. It does not publish a pinout, USB-C or USB-PD behavior, cable requirements, regulator/protection design, output-current limit, voltage tolerance, heat test, electrical-safety certification, tested SAO matrix, or universal compatibility result.
Sourcecaelyb's Uberflux listing describes a USB-C-to-SAO Power Back with maker-described 5 V-to-3.3 V conversion that lets SAOs run without a host badge, including desk or shelf display. As reviewed on 2026-08-04 it showed $7, 59 sold, 81 remaining, DC34 BadgeLife Village/LineCon/Queercon pickup labels, and post-DC34 CONUS shipping. It is a third-party standalone SAO companion associated by the maker with DEF CON 34, not an official conference item or a main-badge-mounted add-on.
