DEF CON 34 · United States · 2026
Public KiCad/Arduino DEF CON 34 project; production and distribution unverified
eggsactly's public `DC-34-Countdown-To-Singularity` repository explicitly calls itself KiCad 6 design files for a DEF CON badge that lets users display an estimate for when the AI singularity will occur. Its README names eight seven-segment displays, a real-time clock, front buttons for changing the estimate, a KiCad board tree, an Arduino firmware tree, and a BOM that includes an ATmega328P-PU, PCF8523T, seven 2×3 SAO connectors, three buttons, 9 V input/battery parts, and display/power components. This is a real, independently documented pre-event source project, not proof of an assembled run, a specific final unit, DEF CON authorization, allocation, sale, delivery, credential function, or a rights-cleared image.
People
The project is published from the eggsactly GitHub account. This credits a public repository-publisher role only; it does not identify a real-world person or assign badge design, hardware/firmware/art authorship, manufacturing, DEF CON affiliation, distribution, event role, or image-reuse authority.
SourceThe record preserves an unusually detailed current independent source trail—native board, BOM, and firmware directions—without confusing openly visible files with a licensed release, a safe assembly recipe, a completed badge run, or an official DEF CON artifact.
The README identifies eight seven-segment displays and a real-time clock. Its published BOM names an ATmega328P-PU, PCF8523T clock, three pushbuttons, seven 2×3 SAO connectors, a 9 V jack/battery path, 5 V and 3.3 V regulator parts, LEDs, capacitors, resistors, crystal components, an ISP port, and display parts. The public source does not establish the final schematic/BOM revision, all component substitutions, any assembled unit, display topology/wiring, board stack-up, 9 V source compatibility, regulator/thermal/current behavior, SAO pinout/electrical limits, protection, testing, compliance, enclosure, or final physical-unit parity.
The repository documents an Arduino 1.8.5 firmware directory and says stock AVR chips need a one-time bootloader programming step before normal Arduino-style flashing. It does not publish a tagged/released firmware image, source-to-device mapping, tested build environment, dependency lock, final fuse/programmer configuration, recovery package, security review, support policy, warranty, or explicit repository license; its published instructions are not treated here as a safe build or programming procedure.
The repository frames the badge around attendees shifting a displayed prediction for when the AI singularity will occur. That source establishes the project's stated interaction theme but does not identify a creator beyond the GitHub account, a Badgelife drop, a price, a recipient or winner, a DEF CON booth, a challenge, a distribution route, or a post-event outcome.
Source-backed hardware metadata
Structured technical signals seeded from public badge documentation, repositories, schematics, firmware notes, or event evidence. These fields are designed for filtering, API use, repair planning, preservation, and future Companion Gear matching.
The public README calls the project a DC-34 DEF CON badge and documents electronic displays, a real-time clock, buttons, a KiCad board tree, an Arduino firmware tree, and a component BOM; production and distribution remain unverified.
Signal sourceThe published BOM labels J4 through J10 as 2×3 SAO connectors, but does not identify an SAO version, pinout, electrical limits, host compatibility, final assembly, or safe installation/use result.
Signal sourceThe README names eight seven-segment displays but does not identify their wiring/topology, model, brightness/current behavior, final board population, or observed physical-unit state.
Signal sourceThe README identifies an Arduino 1.8.5 firmware directory and a bootloader path for stock AVR chips, without establishing a tagged/released build, final event firmware, reproducible toolchain, or support status.
Signal sourceRepair, preservation, and legal lab context
Parts, tools, and supplies that match this badge's documented hardware, protocols, or preservation needs. These are category-level recommendations, not compatibility guarantees.

This badge has a documented SAO connector. Matched technical signals: SAO.
Vendor link · selected for technical relevance
I2C adapter supplies for badge add-ons, sensors, and lab documentation.
SAO workflows often use I2C-compatible add-on testing and bench documentation. Matched technical signals: SAO.
Vendor link · selected for technical relevance
Extension wiring and jumper supplies for testing or displaying SAO add-ons away from the main badge.
Extension wiring is useful for testing and displaying SAO add-ons. Matched technical signals: SAO.

Lifecycle
The README says the badge lets users display an estimate for when the AI singularity will occur, with front buttons that shift that estimate, eight seven-segment displays, and a real-time clock. It documents a source-project interaction concept, not an assembled unit, final screen/readout behavior, calibrated clock, usability result, event challenge, prize, or completed distribution.
SourceThe README points to an Arduino 1.8.5 firmware directory and says stock AVR chips need a one-time bootloader step before normal Arduino flashing. This preserves an implementation trail without reproducing programming commands or claiming a safe procedure, final fuse/programmer configuration, reproducible build, tagged firmware, deployed badge binary, recovery path, support, or warranty.
SourceThe README's BOM names an ATmega328P-PU, PCF8523T real-time clock, three pushbuttons, seven 2×3 SAO connectors, a 9 V jack/battery path, regulator parts, LEDs, display components, and an ISP port. It identifies a design inventory, not a verified final board, complete/electrically accurate BOM, component availability, safe power path, SAO pinout/current budget, host compatibility, or tested build.
SourceOperational history
The catalogue can link the source project without turning development instructions into a recommendation to program hardware, treating visible files as a final/reproducible deployment, claiming legal reuse, or publishing a repository visual without complete image provenance.
The record links a real design trail without presenting it as a complete electrical specification, a validated battery/adapter recommendation, a universal SAO compatibility claim, a safe assembly guide, or a manufactured quality record.
The catalogue records a named, technically documented independent project without presenting it as an official DEF CON badge, an attendee entitlement, a credential, a completed physical run, or proof that any participant received one.
The United States record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
