DEF CON 34 · United States · 2026
Publicly announced 100-unit ESP32-S3 badge offering planned for DEF CON 34
A contemporaneous public r/Defcon post calls this a Sneakreaper limited-edition DEF CON badge and says only 100 would be available at a Sneakreaper Industries booth; the post author later replies with Hall W4 and $150. The same post names an ESP32-S3-MINI-1-N8, Wi-Fi, Bluetooth, 13.56 MHz NFC, and programmable LEDs. Crucially, it says that most listed capabilities will not be ready out of the box: only LED colour/brightness changes, a hidden software CTF or scavenger hunt, and NFC read/write are marked as available on DEF CON day 1. The official DEF CON forum fixes the related conference at the Las Vegas Convention Center on August 6-9, 2026. These sources support a real independently announced pre-event hardware offering with a bounded day-one feature claim, not verified seller identity or Sneakreaper Industries relationship, official booth authorization, completed manufacture, final inventory, sale, handoff, electrical design, firmware release, future functionality, lawful-use assurance, DEF CON organizer affiliation, conference admission, or reusable-image rights.
People
The public Reddit account authored the offer post and replies with the stated price and Hall W4. This records only a public-post attribution; it does not verify the person's legal identity, engineering or artwork authorship, relationship to Sneakreaper Industries, seller authority, manufacture, DEF CON role, or image-reuse authority.
SourceThe post is unusually valuable despite its modest source trail because it clearly separates hardware capability from software actually promised on the first conference day. The catalogue can retain the stated ESP32-S3, wireless, NFC, LED, price, quantity, and pickup context without turning a pre-event Reddit offer into a completed run, a full feature list, a sanctioned security tool, or an official DEF CON credential.
The public post names an ESP32-S3-MINI-1-N8 plus Wi-Fi, Bluetooth, 13.56 MHz NFC, and programmable LEDs. It does not identify the board revision, radio or antenna design, NFC controller or antenna, LED count/type/current, battery, charging or USB path, power budget, buttons, display, storage, enclosure, dimensions, materials, connector/pinout, schematic, BOM, PCB/Gerbers, assembly process, test results, safety instructions, RF/NFC compliance, final component population, or a host-compatibility matrix.
The post explicitly marks only LED colour/brightness adjustment, a hidden software CTF or scavenger hunt, and NFC read/write as day-one functions. It says other listed capability categories are not ready out of the box and may be deferred or left for people to code. No firmware source or binary, build or flash procedure, CTF content/rules, NFC data format, Wi-Fi/Bluetooth protocol, update/recovery path, software license, security review, privacy policy, supported-device list, or final shipped feature inventory is publicly identified.
The listing is framed as a limited Sneakreaper badge for DEF CON 34. Its public author says only 100 are planned at a Sneakreaper Industries booth, then answers prospective buyers with a $150 figure and Hall W4. DEF CON's own forum confirms the event dates and Las Vegas Convention Center venue, which were still upcoming in this August 4, 2026 source pass. Those statements establish a pre-event independent offer associated with DEF CON 34, not a verified commercial relationship, booth authorization, completed purchase, transfer, pickup, conference sponsorship, organizer-issued badge, admission right, or event outcome.
Lifecycle
The author says that most listed capability categories will not be ready out of the box and that only LED colour/brightness adjustment, a hidden software CTF or scavenger hunt, and NFC read/write are available on DEF CON day 1. That is an announced capability boundary, not a public firmware release, working demonstration, final event outcome, or guarantee of feature availability for every unit.
SourceThe post says only 100 would be available at a Sneakreaper Industries booth. In replies, its author gives $150 and Hall W4. The source does not document a checkout page, seller identity, order count, stock ledger, payment, refund/replacement terms, exact booth authorization, completed manufacture, handoff, delivery, remaining stock, or post-event outcome.
SourceThe post names an ESP32-S3-MINI-1-N8 with Wi-Fi, Bluetooth, 13.56 MHz NFC, and programmable LEDs. It does not provide a schematic, BOM, antenna/NFC design, power path, interface specification, final revision, performance measurement, safety guidance, or proof that every proposed unit has that exact hardware population.
SourceOperational history
The record does not represent deferred or merely hardware-capable categories as shipped functions, supported workflows, secure behavior, or final user experience.
The record preserves named hardware without turning it into a complete, electrically safe, interoperable, or production-verified design.
The catalogue presents a real independent event-associated badge offer without misclassifying it as an official conference credential, organizer product, admission item, or verified vendor-booth activity.
The record remains source-backed and image-free rather than copying Reddit media, previews, screenshots, social posts, thumbnails, placeholders, or generated approximations.
The catalogue records the concrete pre-event offer while leaving attribution, seller relationship, availability, sale, fulfillment, and event outcome explicitly unresolved.
Readers can identify the announced wireless/NFC surface without treating the record as a sanctioned operational guide, a privacy guarantee, a compliance claim, or permission to use the badge against systems or media they do not own or control.
