Open Sauce 2026 Badge

SauceBot / Arduino Sopracciglio electronic badge with a post-event KiCad archive

Open Sauce 2026's SauceBot badge is documented by Caleb Marting's post-event public archive as an Arduino MKR Zero-compatible electronic badge with native KiCad sources, firmware, a microphone, button, red LEDs, battery holder, and optional Simple Add-On headers. The archive says at least two attendees hacked badges Saturday night and brought four new games on Sunday; an independent attendee firmware archive also describes receiving an eyebrow module and replacing the original Bop It-style firmware. Together the sources establish a real festival artifact and hands-on hacking trail, not a universal attendee allocation or organizer-owned source release.

Original Series Tricorder Badge (DEF CON 34)

Independent planned sensor-described Original Series Tricorder badge sale at DEF CON 34

MakeItHackin's public DEF CON 34 Badgelife response lists a new Original Series Tricorder badge, says it will be available on-site at DEF CON through Hacker Warehouse for approximately $125, and describes it as celebrating 60 years of Star Trek with various sensors. The source field for the current badge is still marked TBD. The same maker's public Tricorder SAO repository, tutorial, and live $30 Tindie listing document a differently named 2025 Tricorder SAO with separate badge-powered and rechargeable-battery forms. Those historical sources establish a related public maker lineage, but they do not map their electronics, LEDs, battery/USB-C details, form factor, price, or distribution to the current $125 Original Series Tricorder badge. This is a source-backed planned independent sensor-described event artifact, not proof of a completed sale, disclosed sensor suite, electronic design, final hardware/firmware, historical-SAO parity, official DEF CON issuance or admission, reusable-image permission, or Star Trek rights-holder authorization.

Ouroboros Badge (DEF CON 34)

Independent CH32V003 bare-metal UART crypto-puzzle badge offered toward DEF CON 34

K Badges' maker-controlled Tindie listing identifies Ouroboros as a $29.99 bare-metal RISC-V-assembly electronic badge on a CH32V003, with a custom UART cryptographic puzzle, a 12-LED Charlieplexed matrix, a circular single-layer PCB with exposed traces, and a hand-soldered two-AA configuration. Its August 4, 2026 storefront snapshot is out of stock; the seller says a new order is coming and hopes to bring some to DEF CON, rather than confirming units, arrival, pickup, or delivery. In a first-person r/Defcon announcement, the maker says they created the project and links the Tindie page and a GitHub technical explainer, while separately offering to arrange a DEF CON pickup by email for Tindie buyers. The product also makes 115200-baud puzzle, cryptographic-framework, low-power, and performance statements, but neither the product nor the maker-linked generic AVR framework establishes a released matching CH32V003 firmware or hardware package. This is a source-backed independent pre-event maker offering, not an official DEF CON badge, registration credential, confirmed fulfillment, verified cryptographic implementation, hardware-safety record, or reusable-image source.

Overglade 2026 Zero-Power NFC E-Ink Badge

Maker-documented RP2040 e-ink/NFC game-jam badge

Kai Pereira's public archive identifies these as Overglade hackathon badges designed for the completed Singapore game jam. The device has an RP2040, passive NFC, an onboard e-ink driver, and an exposed ticket-shaped PCB with public KiCad and MicroPython source trees. Official Hack Club pages establish the event, but not a badge entitlement or all-recipient allocation.

Payment Village DEF CON 34 Volunteer Village Badge

Officially announced pre-event volunteer access credential

Payment Village's official DEF CON 34 volunteer notice says volunteers will receive access to the conference through a village badge, alongside a village T-shirt and learning opportunities. The village's official event page confirms the August 6-9 Las Vegas programme. This source-backed record models the stated pre-event volunteer identity/access artifact only; it does not identify a physical form, electronics, access-control mechanism, issued quantity, or a connection to the separate 2025 Vulnerable ATM Badge.

Portal Badge (DEF CON 34)

Pre-event CH32V303 Portal puzzle badge from a public DC34 source tree

BigFuckingBadge's live DEF CON 34 page calls this year's Portal Badge a 14×14-inch Companion-Cube-shaped, touch-activated badge, marks presale open with limited quantities, and advertises $120 before DEF CON 34 or $150 through hackerwarehouse during the con. A public GitLab hierarchy at `hexum-public-share/bfb/dc34/public/badge/portal-badge` contains separate software, hardware, and sound projects for the same Portal-themed badge. The source names a `ch32fun-portal-badge` firmware project and a `ch32v303-48lqfp-portal-badge` board project; its current software configuration targets a CH32V303CBT6 with PlatformIO and ch32v003fun. The committed firmware defines 85 LED pixels, fourteen active-low inputs, SD-card-backed audio with DAC playback, flash-persisted unlock state, a serial Portal Gun SAO/badge-to-badge protocol, and diode-solder-on detection. Its design document describes standby, Nyan, and a four-level Portal puzzle game built around spheres, portals, fire, and unlockable features. Public commits show software “final code checks” and hardware acrylic SVG work on August 2, 2026. This is a source-backed pre-event independent record, not proof of a completed sale, physical run, event allocation, pickup, official DEF CON credential, final binary, safety validation, third-party-IP permission, or reusable-image rights.

Portal Gun SAO (DEF CON 34)

Independent PFC161 touch-and-four-LED companion SAO announced for DEF CON 34

BigFuckingBadge's public DEF CON 34 Badgelife response lists a new $20 PORTAL gun SAO and says touching its end changes animated colors and interacts with the PORTAL Badge. The maker's live DEF CON 34 page independently describes a $20 Portal-gun companion with blue, orange/red, and off modes plus interaction with that year's Portal Badge. Hexum064's public `portal-gun-sao-dc33-code` source targets PFC161, defines a four-pixel LED buffer, blue/orange color states, a capacitive-touch threshold, and a touch-triggered state update; the public hardware tree holds KiCad, BOM/position, Gerber, and acrylic files. The source repositories retain `dc33` in their names, so they are an implementation/reuse trail rather than proof of a newly designed or unchanged 2026 production revision. Together the sources establish a real planned independent electronic SAO associated with DEF CON 34—not official DEF CON issuance, admission, confirmed fulfillment, a finalized host-compatibility claim, final hardware/firmware parity, third-party-IP permission, a source-license grant, or a rights-cleared image.

Puzzled Hackers LED Badge (DEF CON 34)

Sold-out independent Puzzled Hackers LED meetup badge for DEF CON 34

Puzzled Hackers' own CTF checkout page calls this a limited-edition LED badge for DEF CON 34 and, in the August 4, 2026 source pass, lists $20 including tax, in-person pickup at the Linq 3535 / Circle Bar on Wednesday August 5 and Thursday August 6 from 7–10 PM PT, no shipping, and exhausted online allocations. A contemporaneous Puzzled Hackers Team announcement says the top 50 CTF participants received free-badge redemption on their accounts, remaining sales were capped to break even, further badges would move to random giveaways after the cap, and collection requires a meetup or arranged DEF CON handoff using an offline QR claim code. It also explicitly says the meetup is free and that an actual DEF CON badge is not required for the first Wednesday gathering. The sources support a real, independently distributed LED badge and a community CTF/meetup context, but not its physical construction, components, firmware, final quantity, free-claim count beyond the stated top 50, delivery, event authorization, DEF CON organizer affiliation, admission, or reusable-image rights.

Pwnterrey 2026 Official ESP32-C5 Badge

Official open-hardware headless ESP32-C5 wireless-security badge with public KiCad and C5 firmware sources

Electronic Cats' public badge-pwnterrey-2026 repository describes itself as the official Pwnterrey 2026 badge and publishes a native KiCad hardware project plus a CERN Open Hardware Licence v1.2 file. Pwnterrey's official site places the free cybersecurity conference in Monterrey on May 29, 2026; Bishop Fox separately corroborates the date and Rincón Tostitos By Jardín 85 venue. The source documents a portable headless ESP32-C5 RISC-V badge with USB-C serial context, NFC tag-emulation circuitry, and GPS material. Electronic Cats' companion repository calls itself official Pwnterrey 2026 firmware and preserves an ESP32-C5 Marauder-derived source and build trail. These sources establish a real official event badge and public design and firmware references, but not a production quantity, registration-tier allocation, final assembled configuration, completed recipient handoff, final signed release, safe operational use, or reusable badge-image right.

SemiTO-V Developer Zone RP2350/GW1N-9 electronic badge project

SemiTO-V's RISC-V FPGA Badge was a limited Developer Zone electronic PCB badge project for RISC-V Summit Europe 2026 in Bologna. Primary team sources name an RP2350 MCU, a GOWIN GW1N-9 FPGA, custom firmware, and a default RV32I core; they say NextPCB produced the boards and planned to bring 25 to the developer workshop. A logistics update then delayed intended June 8 distribution. The source record supports real physical boards and a 2026 event association, not a final unit count, completed recipient delivery, or the precise current post-event design revision.

RTV D20 Badge (DEF CON 34)

Planned $80 Red Team Village badge with an on-site sale statement

Red Team Village's own public DEF CON 34 Badgelife response lists a new badge named RTV D20, says it will be available on site at DEF CON through the village, and gives an $80 price. The Village's official events page places Red Team Village at the Las Vegas Convention Center on August 6-9, 2026. These primary event and self-submission sources are sufficient to seed a planned village-associated artifact, but they do not identify whether the badge is electronic or non-electronic, its physical design, any components, functions, firmware, game, CTF role, quantity, final sale outcome, registration relationship, or reusable-image rights.

Root Access SAO (DEF CON 34)

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.

The official Seasides and HW101 pages establish a Goa Hardware Hacking Village where people soldered take-home badges and worked on a hidden hardware/firmware challenge. A public project-owner archive calls a concrete board the Seasides 2026 Roulette Badge, says that more than 300 participants assembled it live, and publishes its C firmware, schematic, and Gerbers. The archive makes this a source-backed maker-documented instance of the village badge, but the official event pages do not independently name the Roulette design or confirm that every village or conference badge used that exact final configuration.

The maker's live Tindie product page also identifies Star Trek SAO Phaser v2.2 as a Hak4Kidz Lab electronic badge wearable and a fun blinky add-on. That page says it can attach to a Badgelife-supported SAO 1.69bis connector, describes side-view and shine-down LEDs illuminating the PCB, barrel, and top tracer, and calls the SAO connector a DIY soldering part. It also says the named v2.2 listing was made for DC31 and is a follow-up to a 2019 v1; its coin-cell pin-wear path was still in works. These sources establish a real planned independent current-event sale and a historical same-name product lineage—not completed DEF CON sales, confirmed Hacker Warehouse stock, a final 2026 production/revision mapping, a supplied coin-cell wearable configuration, a complete circuit/firmware archive, official DEF CON issuance or admission, reusable-image permission, or Star Trek rights-holder authorization.

The Beer SAO / BCCC Temperature Badge (DEF CON 34)

Pre-event RP2350 temperature-measuring Simple Add-On for DEF CON 34's BCCC

The live maker listing for The Beer SAO, the public `aerospace-venoms/BCCC_Temperature_SAO` source tree, and BCCC's own DEF CON 34 page document an independent temperature-measuring Simple Add-On associated with the Beer Chilling Contraption Contest. The marketplace's August 4, 2026 payload shows a $45, 150-unit presale with 28 sold and 122 remaining, two BadgeLife Village pickup slots, and no shipping. It describes a roughly 100 mm beer-cup SAO with a waterproof temperature probe, triple seven-segment display, RP2350 with 2 MB flash, USB-C, and a supplied 180-degree adapter for the upside-down DC34 host ports. The source tree identifies an RP2350A, W25Q16 flash, DS18B20 temperature sensor, RGB-independent brightness control, Pico-SDK firmware, KiCad design files, a versioned UF2, and batch programming/soak-test tooling; it says BCCC winners receive copies while stock lasts. This is a source-backed pre-event independent badge record, not proof of final manufacture, pickup, contest results, host compatibility, temperature accuracy, safety, final firmware, DEF CON organizer endorsement, conference admission, or reusable-image rights.

The Shattered Shard (DEF CON 34)

Public player-guide electronic challenge badge; allocation unverified

BigDawgDave's public GitHub repository describes itself as the public repository for a DEF CON 34 RM-Cyber challenge badge called The Shattered Shard. Its Player Guide tells participants to use an assigned badge with a charged battery, a local Wi-Fi/browser interaction, a data-capable USB cable, a serial terminal, and one labelled-jumper task. It is enough evidence to preserve a separately named, independently documented pre-event electronic challenge badge, but it does not prove the RM-Cyber relationship, organizer authorization, hardware provenance, sale or giveaway, run size, allocation, physical handoff, completed on-site use, admission function, or a rights-cleared image.
