ATtiny402 DeLorean PCB-art conference badge
An electronic PCB-art conference badge documented by its maker and badge sponsor, Punk Security, for BSides Cheltenham 2023. Punk Security's own dated event listing identifies its June 3 Cheltenham appearance as that year's badge-sponsor engagement, names a talk on building the BSides Delorean badges, and describes them as functional conference badges. The public `bsides-cheltenham-2023-badge` repository calls the artifact the Delorean badge, reports that parts sold for badge completion on the day raised more than £300 for Mind, and preserves EAGLE, Gerber, library, and Arduino firmware material. Its parts list names an ATtiny402, button, CR2032 clip, NeoPixel, and 3528 blue LED. The reviewed sources do not establish organizer-side 2023 confirmation, venue, production quantity, attendee allocation, individual handoff, final unit-by-unit configuration, completed assembly count, safety validation, or reusable image provenance.

ATtiny402 UFO PCB badge with source-described activity material
An electronic PCB badge identified by Punk Security's public source archive as the UFO badge for BSides Cheltenham 2024. Its repository preserves EAGLE, Gerber, Arduino firmware, vector-art, 3D-case, and activity-booklet material, and names an ATtiny402, button, CR2032 clip, and 5050 NeoPixel. The archive says the activity booklet was given out on the day. Punk Security's historical event timeline separately says it was the badge sponsor and had UFO badges, but currently renders that entry with an inconsistent early-2023 timestamp; the record therefore uses the repository's explicit 2024 badge identity without inventing an exact date or venue. The reviewed sources do not establish organizer-side 2024 confirmation, production quantity, attendee allocation, individual handoff, final unit-by-unit configuration, activity participation or outcome, safety validation, or reusable image provenance.
Little Shop of Horrors ATtiny402 soil-sensor PCB badge
An electronic PCB badge documented by its maker and badge sponsor, Punk Security, for BSides Newcastle 2024.

Independent brass Coin M0 text-adventure and CircuitPython eChallengeCoin planned for DEF CON 34
AoSC's 2026 eChallengeCoin page describes a planned limited run of 40 brass electronic coins, framed as gifts for participants in its Choose Your Own Charity initiative rather than items for sale. It describes a Sara and the Missing Artifacts terminal text adventure, three groups of NeoPixels, a small speaker, one large touch pad for CircuitPython, no battery, 46-gram brass construction, and a Micro-USB serial connection; its form says a $100-or-greater youth-STEM-charity donation may receive a 2026 coin by U.S. mail or DEF CON pickup. The same page links the official CircuitPython Bradán Lane STUDIO Coin M0 profile as the build specifically for the eChallengeCoin. That profile identifies an ATSAMD21G1A, 4 MB flash, three RGB-NeoPixel groups, three capacitive touch pads, a speaker, and native USB-C. The linked primary sources therefore document a real planned independent DEF CON 34 electronic artifact while also disagreeing about USB connector type and touch-pad count; this record preserves the conflict rather than resolving it. They do not establish final manufactured-unit parity, confirmed donations or delivery, charity/tax treatment, official DEF CON issuance or admission, game-source licensing, or reusable-image rights.
Published pre-event RP2354 BadgeLife village badge; allocation and handoff unverified
Badge.Life's public archive documents Badgey Bodgerton as the Badgelife Village Badge for DC34 / 2026. Its published guide names an RP2354 microcontroller with integrated flash, eight addressable RGB NeoPixel LEDs, three user buttons, one user-installed 3 mm challenge LED and polarized buzzer, USB-C power, USB CDC serial CLI, UF2 firmware flashing, a single-cell 18650 battery with charging and protection circuitry, two Simple Add-On v2 headers, and an infrared receiver. It also documents a supplied bodge-wire challenge and supplied LED/resistor/buzzer challenge parts. This establishes a distinct, technically documented pre-event BadgeLife village electronic badge, not proof that DEF CON designed, issued, or will distribute it; that it is a Human admission credential; that every participant receives one; that a final badge run, pickup, or delivery occurred; or that any displayed image is cleared for reuse.
Independent ATtiny814 24-NeoPixel minibadge holder offered for DEF CON 34
Cabinet of Distinctm1nd's live Beelzebub Minibadge Holder listing is a $45 offer that displayed sold out in this August 4, 2026 source pass and says DEF CON pickup is only for August 6-8 pickup attendees. The maker describes 24 NeoPixel LEDs, an ATtiny 814, USB-or-battery power, custom or pre-programmed themes, and an assembled board whose minibadge headers and optional battery holder still require soldering; it also says shown minibadges are not included. The public `distinctm1nd/beelzebub_minibadge_holder` repository corroborates a holder for five minibadges, a 24-LED source layout, button-selected theme code, and KiCad/BOM material. Its hardware archive includes a filename with `saintcon_2025`, so it is a useful implementation and lineage source, not proof of a completed SAINTCON distribution, an unchanged final 2026 build, final fulfillment, official DEF CON issuance, a complete source-license grant, or reusable-image rights.
Independent ATtiny814 five-NeoPixel minibadge holder offered for DEF CON 34
Cabinet of Distinctm1nd's live Krampus Minibadge Holder listing is a $45 offer that displayed sold out in this August 4, 2026 source pass and limits DEF CON pickup to August 6-8 pickup attendees. The maker describes five NeoPixel LEDs, an ATtiny 814, microcontroller development-pin access, USB-or-battery power, and custom or pre-programmed themes; it says minibadge headers and the optional battery holder require soldering and shown minibadges are not included. The public `distinctm1nd/krampus_minibadge_holder` repository corroborates an ATtiny814 holder described as holding six minibadges, a five-LED firmware layout, button-selected theme code, and KiCad/BOM material. Its hardware archive includes a `saintcon_2025` filename, so the tree is an implementation and lineage source—not proof of completed SAINTCON distribution, final 2026 production parity, fulfillment, official DEF CON issuance, a complete source-license grant, or reusable-image rights.
Pre-event ATMEGA328 multi-layer BadgeLife soldering kit
NYC Badge is an independent, pre-event BadgeLife soldering kit offered through Uberflux's Def Con 34 Badge Pickup. The storefront lists a $60 Original option and, at this August 3 source pass, shows the 20-kit listing as OUT with zero remaining and 20 sold. Its published kit list names a layered PCB build, pre-soldered lights, a pre-flashed ATMEGA328, crystal, passive parts, switches, an AAA holder, and included SAO material. This records a real upcoming small-run hardware listing, not final pickup, completed attendee delivery, or an official DEF CON admission credential.
Official ESP32-S3 NFC e-paper badge with post-event Apache-2.0 source release
NorthSec 2026's official registration page lists a new social electronic badge as an included item for conference, CTF, combo, and training ticket holders while supplies lasted. The official competition page's retained 2026 Solarpunk section says the hackable electronic badge was fully integrated into the CTF, with badge challenges worth points and on-site badge-firmware tampering among the physical tracks. Official villages pages document badge pickup through attendees' nSec order QR codes, soldering-village activity where attendees could enhance their badge with blinking electronic parts, and a badge museum. On August 3, after the May event, NorthSec published the separate Apache-2.0 `nsec/badge-2026` repository. Its commit-pinned hardware and source tree documents an ESP32-S3 badge design with an ST25R3916 NFC front end, six buttons, eighteen WS2812/NeoPixel LEDs, a 200×200 GDEH0154D67 / SSD1681 e-paper path, KiCad design files, production BOM/CPL/Gerbers, PlatformIO firmware, conference/CTF partitions, CTF assets, and dock/SAO directories.
Pre-event ATtiny1616 cedar interactive Simple Add-On for DEF CON 34
MakeItHackin's live Uberflux listing describes Root Access as a home-milled Tennessee-cedar add-on built for the DEF CON 34 badge and says it also works with a standard six-pin SAO header. Its August 4, 2026 marketplace snapshot lists $50 and a seller state of 15 sold from a listed total of 100, with BSides Las Vegas and Linq Circle Bar drop labels. The maker's public RootAccess guide independently identifies an ATtiny1616, ten addressable RGB pixels, eleven discrete LEDs, fifty built-in animations, a physical button, I2C address 0x50, and non-volatile USERROW state. It documents standalone operation and host-controlled lighting over I2C, plus separate GPIO 1 and GPIO 2 circuits that can be used as LED outputs or button inputs. This is a source-backed pre-event independent SAO record, not proof of final manufacture, actual drop handoff, every listed compatibility claim, safe electrical integration, DEF CON organizer affiliation, conference admission, or reusable-image rights.
