Hackbat DEF CON 32 Badge
The Hackbat Badge is an unofficial DEF CON 32 badgelife board documented by the Hackbat project page and GPL-3.0 GitHub repository, with ESP32-C3 Wi-Fi/BLE, OLED display, WS2812 LEDs, six buttons, AA-cell case support, and production files.
Dante's Inferno Badge (DEF CON 32)
redactd's Tindie listing introduces Dante's Inferno as an electronic badge just in time for DefCon 32, inspired by the Dante's Inferno Room. It describes three connected circuit boards, special two-color solder mask on the top two boards, sixty LEDs, an included CR123A battery, a populated SAO v1.69bis port, custom-printed box, laser-cut foam insert, and lanyard. The same maker's public repository documents a USB/UF2 firmware-update procedure and a July 2024 v1.1 release for pre-sale 1.0/1.01 units. A Hacker Couture DEFCON 33 product list later repeats the $100 product and core three-board, sixty-LED, CR123A, and SAO claims. Together, these sources establish one source-backed independent 2024 DEF CON 32 artifact with a later 2025 vendor-list recurrence, not an official DEF CON credential, a second DC33 badge, confirmed distribution at either event, a complete electrical design, a licensed source-code archive, or reusable-image rights.
Retia DEF CON 32 Badge
Retia, LLC's public repository is currently named `DefconBadge2026`, but its immutable first source-release commit calls the project `DEF CON badge (2024)` and its README is titled `DEF CON Badge (2024) — ESP32-S3`. That source snapshot includes KiCad and fabrication material named `2024_def_con_badge_v1`, a badge photograph, and high-level hardware documentation. The official DEF CON archive identifies the 2024 event as DEF CON 32, so the record is attached to that existing edition as a retrospectively documented independent artifact; neither Retia nor DEF CON source reviewed here calls it an official Human badge, an attendee entitlement, or a confirmed event handoff.

published July 28, 2024; issue details unpublished
v1.1 pre-sale corrective release
The v1.1 release says some pre-sale 1.0 or 1.01 badges should flash the update to fix an unspecified issue, and says `enable, sh ver` can check that the badge is on the 1.1 build. It does not identify the issue, affected count, unit identifiers, changelog, validation, rollback, installed population, or update outcome.

high-level listing and vendor-list claims
Three-board 60-LED, CR123A, and SAO surface
The maker listing and later Hacker Couture list describe three connected boards, special two-color solder mask on the top two boards, sixty LEDs, an included CR123A battery, and one populated SAO v1.69bis port. They do not identify the controller, LED or battery characteristics, power design, SAO pinout, electrical limits, circuit, schematic, BOM, Gerbers, or safety validation.
Dante's Inferno Badge (DEF CON 32)
listing wording published; fulfillment unconfirmed
Custom box, foam insert, lanyard, and shipment statement
The listing says the badge comes in a full-color custom-printed box with a laser-cut foam insert and unique lanyard, and says it ships ground in the United States with the battery removed for air shipping. It does not confirm which purchaser or event recipients received every listed component, final packaging variant, shipping availability, completed shipment, or battery compliance outcome.

README instruction published
USB UF2 firmware-update procedure
The maker repository says to power the badge, open a serial connection at 1200 baud to force boot-select mode, mount the resulting USB drive, and drag a released UF2 firmware image onto it. Pre-sale badges with acrylic require manual boot-button access while powering on. The source does not identify the controller, serial device behavior, bootloader implementation, erase/recovery model, verification, signed-image process, support path, or safety implications.

ESP32-S3 badge design and interface source trail
The immutable README describes an ESP32-S3, color touch display, LoRa radio, storage, buttons, LEDs, sound, expansion, and two-AA or USB-C power surface. It is a documented design summary, not a final-batch bill of materials, final hardware revision, safety claim, or configuration guide.
Retia DEF CON 32 Badge
public immutable source tree
2024_def_con_badge_v1 KiCad and fabrication archive
The first public source-release commit preserves KiCad 8, schematic, and fabrication files whose paths identify 2024_def_con_badge_v1. This demonstrates a source-published hardware archive without proving the date of manufacture, board quantity, assembled population, test results, physical distribution, or a right to manufacture derivatives.
Retia DEF CON 32 Badge
July 2026 release surface
Later public software-release timeline
The repository's public releases visible in the reviewed source pass are dated July 2026, after the 2024 event. They establish a later public software trail without identifying software installed on any 2024 unit or a current supported operating path.
Retia DEF CON 32 Badge
immutable source snapshot published after event
2024 source identity in a later DefconBadge2026 repository
Retia's current repository name says DefconBadge2026, but its metadata calls the project a Retia 2024 DEF CON badge and the immutable first source-release commit/README explicitly say 2024. This records the source conflict and 2024 provenance without treating the repository label as a 2026 event association.
Operational history
Issues & Camp Impact
The listing says the badge runs on an included CR123A and says it ships ground with the battery in the United States while the seller will remove the battery for air shipping. It does not identify the cell chemistry/brand/protection, holder, polarity protection, current draw, charging behavior, thermal/short-circuit precautions, storage/transport conditions, replacement compatibility, legal shipping compliance, or test evidence.
The catalogue records the published battery and shipment wording without treating it as a complete safety, transport, charging, or replacement-battery procedure.
The product was introduced for DefCon 32, later appears on a DEF CON 33 Hacker Couture list, and the Tindie page says it sold out in September 2024. This pass did not recover a production count, event schedule, booth location, receipt, purchaser/recipient list, attendee report, pickup/shipping record, vendor after-action, unit history, or proof that the 2025 vendor listing used an identical run or remaining 2024 inventory.
The record preserves the maker-stated 2024 origin and the separate 2025 listing without creating a duplicate DC33 badge or treating either listing as confirmed event distribution.
The source documents a hardware design and preserves KiCad/fabrication files, but it does not establish a final board revision, component substitutions, display or radio population, antenna configuration, battery brand/capacity, power-path limits, runtime, charging behavior, power safety, radio compliance, electrical test results, manufacture, quality control, or a physical-unit inventory.
Source-backed component and interface references remain a bounded design trail rather than a universal physical-badge specification, safety certification, performance claim, manufacturing record, or operating guidance.
The public repository says it will contain information and software updates, and its release/README document a UF2 update path, but the reviewed tree does not provide readable firmware source, build tooling, hardware design, a license file, source history, change log, game/application documentation, security analysis, or an image-use license.
Readers can follow the documented update surface without assuming the badge is open source, reproducible, auditable, redistributable, or supported beyond the published high-level instructions.
DEF CON 32 Badge
note
Public sources document the save issue, firmware archives, GB Studio game source, and DEF CON's response to contractor-credit and firmware claims, but this pass does not adjudicate every dispute, audit every firmware build, or mirror every hardware/game asset.
The catalogue records the verified public badge surfaces and flags that the production and firmware story needs a deeper artifact-level chronology.
Hackbat DEF CON 32 Badge
warning
The README warns that the DEF CON 32 received version had D9 misplaced, leaving USB 5V directly connected to the battery; the repository says the current revision fixes the problem.
The catalogue preserves the battery/USB safety erratum and does not treat all Hackbat boards as identical to the fixed public revision.
Sources name three boards, sixty LEDs, CR123A, and one SAO port, but do not identify controller, board interconnect, LED part/current, power path, regulator, battery holder/protection, voltage/current limits, USB behavior, SAO pinout/rating, circuit, schematic, BOM, PCB/Gerbers, dimensions, materials, assembly, test matrix, safety guidance, or compliance evidence.
The catalogue retains a traceable physical surface without representing it as a complete electrical design, measured power profile, host-compatibility guarantee, or safety validation.
The Hackbat visual uses the GPL-3.0 `doc/3d.png` render from the official theHackbat/defcon32_badge repository.
The record has a rights-cleared official upstream raster render with source URL, license, attribution, local source preservation, and optimized WebP delivery while avoiding generated or placeholder imagery.
The maker says the badge was introduced just in time for DefCon 32 and a later vendor list places it in a DEF CON 33 product context, but neither source says DEF CON issued it, included it with registration, made it a Human-badge replacement, granted access, or endorsed it as an official credential.
The catalogue classifies Dante's Inferno as an independent badge tied to public DEF CON market contexts, not as an organizer-issued conference credential, admission item, or universal attendee handout.
GitHub metadata reports no detected license and the immutable source tree has no root LICENSE or COPYING file. The README includes a badge photograph, but the source does not pair it with a selected-image reuse basis, named attribution, processing provenance, or permission covering artwork, marks, event naming, or media.
The catalogue cites the source archive but does not copy its badge photo, board images, code, fabrication files, artwork, logos, trademarks, screenshots, or a generated approximation.
No Dante's Inferno Badge image is published because the reviewed maker listing, repository, release, and vendor-list sources do not pair a selected factual artifact image with a reusable license or explicit permission basis, attribution, source URL, and processing notes.
The entry remains source-backed and image-free rather than copying storefront, repository, release, vendor-PDF, social-media, screenshot, placeholder, or generated imagery.
No Retia DEF CON 32 Badge image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.
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.
DEF CON 32 Badge
note
No local DEF CON 32 badge photo has been added because official store/news images, Raspberry Pi images, community blog images, and attendee images have not been paired with a complete reuse basis, attribution string, and processing record for this catalogue.
The entry remains image-free rather than copying official, press, or community photography without provenance.
Retia's archive documents a badge design and source tree, but reviewed sources do not say DEF CON commissioned, approved, sold, issued, or distributed it. They do not identify a price, quantity, sale, giveaway, ticket tier, pickup, booth, recipient, delivery, replacement, admission, access-control, Human-badge, or Black-badge role.
The catalogue treats this as an independently documented event-associated badge, not an official DEF CON 32 attendee badge, credential, universal handout, completed distribution, or organizer-endorsed artifact.
The v1.1 release says pre-sale badges with firmware 1.0 or 1.01 should flash an update to fix an unspecified issue, while the README describes an acrylic-dependent manual boot-button path. It does not identify the issue, which serials were affected, firmware integrity, backed-up state, user-data effects, failure recovery, rollback, host compatibility, support, or the number of badges successfully upgraded.
The catalogue preserves a documented corrective-update trail without claiming the issue's severity, universal applicability, successful remediation, or a risk-free flashing process.
The maker page shows $100 and says the badge has been sold out since September 7, 2024; the later Hacker Couture list also shows $100. Neither source establishes stock relationship, production quantity, buyers, payments, event pickup, shipment, refunds, replacements, resale, support, packaging completion, or completed delivery.
The catalogue keeps distinct seller/vendor snapshots instead of turning a displayed price or sold-out state into proof of event sale, recipient allocation, or fulfilled ownership.
The later archive contains examples and optional software packages, and the visible release surface is dated July 2026. No reviewed source identifies a 2024 installed image, source-to-unit mapping, signed release, default state, user-data handling, support policy, recovery policy, or safe current operating procedure. No code, flashing, configuration, connection, radio-use, or recovery directions are reproduced here.
The record links historical source evidence without presenting a later archive as confirmed 2024 event software, a secure deployment, a supported modification workflow, or operational instruction.
Retia's public repository name says DefconBadge2026, while its current description, immutable first commit, README, and hardware filenames label the project 2024. DEF CON's official archive makes 2024 DEF CON 32, so the catalogue attaches the artifact to that edition as an explicit calendar mapping. No reviewed Retia or DEF CON page calls this artifact by the exact DC32 name or provides a contemporaneous 2024 publication date.
The record preserves the source's 2024 identity and its catalogue placement without silently converting a later repository name into a 2026 badge, an official DEF CON classification, or a verified contemporaneous event artifact announcement.
Hackbat was designed specially for DEF CON 32 and source text references people who received it at DEF CON, but the public sources do not make it the official DEF CON 32 attendee badge or state a complete distribution quantity.
The catalogue keeps Hackbat as an unofficial DEF CON 32 badgelife record separate from the official RP2350 DEF CON 32 Badge.
