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.
People
The community announcement is signed by the Puzzled Hackers Team and directs participants to the Team's CTF checkout. This records its publicly stated project/publisher role without inferring individual hardware authorship, manufacture, DEF CON organizational status, or image-reuse authority.
SourceThis record preserves a small but clearly documented DEF CON 34 community artifact whose acquisition model joins a public CTF, free claims, paid break-even support, QR redemption, and meetup handoff. The catalogue can identify it as an LED badge without making the common leap from a product name to an invented PCB, radio, MCU, game, or firmware specification. It also keeps an important distinction visible: an independent pre-con meetup badge does not grant conference access, and a seller's sold-out state does not prove that each claimed badge was ultimately handed over.
The official Puzzled Hackers checkout page calls the artifact a limited-edition LED badge. It does not identify a PCB, microcontroller, display type, LED count or color, battery, charger, USB port, radio, connectors, sensors, dimensions, enclosure, materials, schematic, BOM, Gerbers, assembly process, firmware, certification, safety documentation, or final manufactured revision. The record therefore treats LED as the source's narrow electronic-artifact classification rather than supplying an inferred technical design.
The sources describe a Puzzled Hackers CTF account as the place where a free-badge redemption may appear, and a receipt / offline QR claim code used for handoff. They do not identify a badge operating system, firmware, binary, source repository, game content, flashing path, protocol, QR format or security design, account-data policy, score-validation method, update path, software license, or proof that the physical LED badge itself runs CTF software. The CTF and QR workflow are recorded as acquisition context, not as badge-firmware claims.
The Puzzled Hackers Team frames its two annual r/DEFCON meetups as free community hangs immediately before and at Hacker Summer Camp, with badges optional rather than required. Its post says everyone may attend, including people without an actual DEF CON badge, and gives the Linq 3535 / Circle Bar location and 7 PM start. The badge's date, pickup, CTF, and DEF CON labeling establish independent community context around DEF CON 34; they do not make the team a DEF CON organizer, turn a badge into admission, or prove a venue, conference, or checkout arrangement was completed.
Lifecycle
The Puzzled Hackers Team says the top 50 participants had Free Badge Redemption attached to their CTF accounts before its final puzzle announcement. It does not publish the leaderboard, account criteria, rank calculation, redemption count, code-delivery mechanics, challenge archive, score review, anti-abuse process, or proof that every eligible participant collected a physical badge.
SourceThe Team says that after the paid cap is reached, distribution moves to random giveaways during the events. It does not identify giveaway quantity, timing, eligibility, selection method, organizer, physical allocation, handoff site, recipient list, or completed result.
SourceThe checkout lists Linq 3535 / Circle Bar pickup on Wednesday August 5 and Thursday August 6 from 7–10 PM PT and says there is no shipping. It says a receipt and offline QR claim code are sent after checkout; the Team says a badge must be collected at a meetup or by separately arranging DEF CON handoff, and the QR may be given to someone else. Those terms do not confirm venue access, checkout completion, code delivery, identity verification, handoff, or redemption outcome.
SourceThe official checkout lists $20 including tax and says all online stock allocations are exhausted. The Puzzled Hackers Team says paid sales were capped at a break-even point. Neither source publishes a unit count, payment ledger, production total, in-person stock, completed sale, delivery, refund, replacement, or post-event availability result.
SourceThe official checkout calls the physical item a limited-edition LED badge. It does not identify a PCB, programmable controller, LED count/color, power system, firmware, radio, connector, or any other engineering surface, so the record preserves the narrow source classification rather than reconstructing electronics.
SourceOperational history
The catalogue retains the public community-acquisition context without supplying private account details, challenge content, player data, unsupported redemption mechanics, or badge-software claims.
The entry does not turn an LED-badge product label into a claimed circuit, operating behavior, repair path, certification, or safety assurance.
The catalogue models a real Puzzled Hackers community badge associated with DEF CON 34 while keeping it distinct from official admission, organizer issuance, and verified event access.
The record remains source-backed and image-free rather than copying the checkout photo, Reddit media, screenshots, social posts, thumbnails, placeholders, or generated approximations.
The catalogue records a real sold-out online offer without converting it into a complete production or fulfillment report.
