Masonic33 Indie Puzzle Badge (DEF CON 33)

Independent ATtiny1616 analog-input puzzle badge with a scheduled DC33 drop and current DC34 continuity

Hak4Kidz Lab's Tindie listing calls Masonic33 a cryptic, interactive badge for puzzle lovers, hackers, and DEF CON attendees. It says two 10 kΩ potentiometers control an ATtiny1616-based board with eleven independently controlled LEDs; players tune analog inputs to unlock a hidden LED sequence and solve four puzzles. The listing also names a UPDI-compatible one-wire programming interface, 4.5 V AAA-battery input with batteries included, a 4.25-inch black-solder-mask/white-silkscreen PCB, custom VHS-style box, patches, lanyard, and stickers. A recovered public DEF CON 33 schedule records a 10:30-10:59 PDT BadgeLife Community Masonic33 Badge drop credited to Heal-Hak4Kidz, while the Hacker Couture DEFCON 33 product list separately shows the Masonic33 Badge at $125. Badge.Life's live DC34 Village Schedule additionally lists Masonic33 Badge — heal at 10:30 AM on Friday August 7 and 11:00 AM on Saturday August 8, 2026, without naming a changed board or revision. These sources establish a real independent 2025 puzzle badge with planned 2026 continuity, not official DEF CON issuance, admission, a confirmed completed drop, a separate DC34 artifact, a complete circuit/firmware archive, a connection to any fraternal organization, or reusable-image rights.

Breadbadge (DEF CON 34)

Current $80 RP2354 breadboard-prototyping badge; fulfillment unverified

Tw0nkus's live Uberflux listing calls Breadbadge a badge by day and a breadboard-prototyping tool by night. It identifies an RP2354A main MCU, INA3221 I2C voltage/current/power monitor, ST7789 SPI display, six WS2812 RGB LEDs, navigation joystick/back button, UART/UPDI/I2C/5 V/3.3 V/debug breakouts, and a Defcon34 drop. The same current listing displayed $80, five remaining, and four sold. Badge.Life's current DC34 Village schedule independently lists Bread Badge by Tw0nkus in its Friday 1:30 PM badge-drop slot. This is enough evidence for a distinct, independently offered pre-event electronic badge associated with DEF CON 34, not proof that DEF CON issued it, that it is an admission credential, that inventory/payment/fulfillment figures are final, that a drop or handoff occurred, or that marketplace images are cleared for reuse.

Firefly Jar SAO (DEF CON 34)

Sold-out pre-event Lepi Labs SAOv3-proposal lighting Simple Add-On for DEF CON 34

Lepi Labs' own Uberflux listing identifies the Firefly Jar as a DEF CON 34-drop Simple Add-On. Its August 4, 2026 marketplace state is out of stock, with 25 sold, zero remaining, and a $25 listed price. The maker describes seven orange reverse-mounted LEDs, an ATtiny824 controller, UPDI reprogramming, vendor commands, and compatibility with Rare Circuit's proposed SAOv3 I2C-based interface. It says the SAO can expose vendor/product IDs, port and command metadata, generic LED controls, and its own lighting modes; the listing also explicitly says it does not support SAOv3 ARP or hot-plugging features. Lepi Labs' first-hand DC34 announcement corroborates planned Friday and Saturday BadgeLife Village drops. This is a source-backed pre-event independent lighting SAO, not proof of final host interoperability, full SAOv3 implementation, firmware release, delivery, DEF CON organizer affiliation, conference admission, or reusable-image rights.

NilbinSec DC34 Main Badge Fuzzer SAO

Independent ATtiny1614 DEF CON 34 badge-challenge fuzzer SAO

NilbinSec's public DC34 Main Badge Fuzzer SAO repository documents a standalone SAO designed to exercise interfaces on the official DEF CON 34 Human badge using information published before the conference. Its README describes three initial modes: GPIO1/GPIO2 stimulation on the left SAO port, an open-drain CPU wake assertion on GPIO4 of the right port, and an I²C-address listening sweep. The repository provides a KiCad schematic, BOM CSV, PCB archive, C firmware, and compiled hex/ELF files. The README explicitly warns that Mode 1 may harm the main badge and says a convention reflash might follow. This is source-backed pre-event independent challenge hardware, not proof of a finished run, sale, giveaway, pickup, compatibility with a final main-badge revision, authorization to probe another badge, official DEF CON issuance or admission, a reusable-image grant, or an explicit software/hardware licence.

OWASP SAO (DEF CON 34)

Source-published 15-pixel touch SAO firmware project; physical artifact and handoff unverified

Punk Security's public repository calls its Arduino sketch "the firmware for the OWASP DefCon 34 SAO." Its final public source snapshot provides an actual `main.ino` rather than an event-labelled name alone: it defines 15 addressable RGB pixel positions, three PTC capacitive-touch nodes, and a README that says the SAO header exposes UPDI for reprogramming. This clears the catalogue threshold for a named, source-published pre-event electronic add-on project. It does not establish a final PCB, microcontroller, power path, exact SAO specification, fabricated unit, approved OWASP or DEF CON relationship, price, allocation, pickup, delivered handoff, credential function, or reusable image rights.

UPDeeDeeI SAO (DEF CON 34)

Sold-out pre-event Lepi Labs UPDI-programmer moth Simple Add-On for DEF CON 34

Lepi Labs' own Uberflux listing identifies UPDeeDeeI as a DEF CON 34-drop moth Simple Add-On. Its August 4, 2026 marketplace state is out of stock, with seven sold, zero remaining, and a $35 listed price. The maker says a CH340E USB-to-serial converter supports UPDI programming of compatible ATtiny devices, names an onboard ATtiny814 with two RGB LED eyes, and describes USB-C plus a flexible FPC tongue used as a functional USB cable. It also claims configurable 3.3 V or 5 V UPDI voltage, SAO or included CR2032 power, and v1.1 pre-event corrections including an FPC power fuse. Lepi Labs' first-hand DC34 announcement corroborates planned Friday and Saturday BadgeLife Village drops. This is a source-backed pre-event independent programming-tool SAO, not proof of final board revision, safe programming configuration, USB/FPC durability, compatible target coverage, delivery, host compatibility, DEF CON organizer affiliation, conference admission, or reusable-image rights.

Volatile Organic Canary SAO (DEF CON 34)

Sold-out pre-event Lepi Labs novelty VOC-indicator Simple Add-On for DEF CON 34

Lepi Labs' own Uberflux listing identifies the Volatile Organic Canary as a DEF CON 34-drop Simple Add-On. Its August 4, 2026 marketplace state is out of stock, with 11 sold, zero remaining, and a $45 listed price. The product describes an SGP40 VOC sensor plus SHT4x temperature/humidity sensor, a two-character fourteen-segment display, RGB LED, ATtiny1616-S controller, UPDI reprogramming, SAO or included CR2032 power, and a lanyard clip. Its maker explicitly says the device is novelty-only and must not be relied on for accurate air-quality measurements; it also records a ten-minute VOC-index warmup and a v1.0 board-order/remediation plan. Lepi Labs' first-hand DC34 announcement corroborates planned Friday and Saturday BadgeLife Village drops. This is a source-backed pre-event independent sensor SAO, not proof of final manufactured hardware, sold orders, safe or accurate air-quality measurement, delivery, host compatibility, DEF CON organizer affiliation, conference admission, or reusable-image rights.
