Sold-out independent three-SAO monorail badge for DEF CON 34
Zach's Hacks' live Shopify listing calls the Monorail Con Badge sold out and says preorder customers will receive pickup details by email, while noting there may be a few extras to trade in person. Its current public product payload marks all three purchase options unavailable: a $65 badge-and-SAOs option, a $150 bundle option that adds Dani.pink's separately made Laser* Tag Badge DS, and an $80 voluntary extra-payment option. The listing describes a small monorail on a track, a clip for a paper ticket not included, three SAOs, a speaker/mini-SD sound surface, blinky lights, and a regulated 3.3 V supply from two AAA batteries. The maker explicitly says final versions may vary and that it has no affiliation with the Las Vegas Monorail. This is a source-backed independent pre-event badge record, not evidence of final manufactured specification, fulfilled pickup/trade, included transit fare, common hardware/firmware ownership with the bundled Laser* Tag badge, DEF CON organizer affiliation, conference admission, or reusable-image rights.
People
The Shopify product payload identifies Zach's Hacks as the vendor of the Monorail Con Badge. This preserves the storefront-publisher credit without inferring an individual identity, final engineering authorship, manufacturing responsibility, transit affiliation, or image-reuse authority.
SourceThis is a clear current snapshot of an independent DEF CON 34 badge offering whose maker publishes both its sold-out state and enough physical/feature detail to model it as a real electronic artifact. The record preserves the distinctive multi-SAO and audio/storage claims while retaining every important boundary: a storefront's live availability is not a production ledger, playful sales language is not an engineering archive, images are not cleared simply because they are maker-published, and neither a monorail theme nor pickup at DEF CON creates transit, conference, or organizer rights.
The maker lists a little monorail on a track, a clip that stores a paper monorail ticket not included, and three SAOs. It says the speaker SAO plays monorail-themed sounds and accepts a mini SD card for MP3 files; it calls out a Sphere SAO for upside-down SAO ports and a High Roller SAO with blinky lights. The product also claims a regulated 3.3 V supply from two AAA batteries. It does not publish a schematic, PCB/Gerbers, BOM, controller/audio/SD/LED part numbers, SAO pinout, battery holder/charge design, power budget, dimensions, enclosure/track materials, assembly procedure, final revision, test data, certification, or a general host-compatibility guarantee.
The public listing only describes an audio behavior and a mini-SD surface for adding MP3 files. It does not provide firmware source or binaries, source repository, microcontroller/platform, playback format limits, media-indexing behavior, a file-transfer procedure, audio source/copyright terms, license, update/recovery path, feature matrix, security/privacy model, or proof of the final installed firmware. The source therefore supports a narrow maker-described sound/storage surface, not an implementation guide or a released software archive.
The maker frames the badge around riding the Las Vegas Monorail to DEF CON, then explicitly says it is not affiliated with the monorail. A contemporaneous first-person post that links directly to the same shop describes three SAOs, DEF CON pickup, and no promised shipping; the product page says preorder customers will receive pickup details by email and separately points to Dani.pink's Laser* Tag Badge DS as a bundled purchase option. These sources establish independent community context and an intended co-pickup arrangement, but do not establish transit sponsorship, ticket inclusion, a fixed pickup location/time, a DEF CON organizer product, registration inclusion, or conference access.
Lifecycle
One sold-out $150 storefront option adds the separately-made Laser* Tag Badge DS from Dani.pink, which the maker says can be picked up alongside the Monorail badge. This records a bundled purchase/co-pickup statement, not shared hardware, firmware, manufacture, ownership, event affiliation, or a guarantee of either badge's delivery.
SourceThe listing says the Sphere SAO works with upside-down SAO ports and the High Roller SAO has blinky lights. The source does not provide a pinout, electrical requirement, LED count/type, firmware, published design, host test matrix, or general compatibility guarantee.
SourceThe product page says the speaker SAO plays monorail-themed sounds and has a mini SD card for adding MP3 files. It does not identify audio hardware, controller, firmware, MP3 limits, file workflow, source audio, media license, volume/safety behavior, or final shipped implementation.
SourceThe maker describes a small monorail on a track, a clip for storing a paper monorail ticket that is not included, and a three-SAO structure. No source identifies the final materials, mechanics, SAO layout, connector pinout, manufacturing method, dimensions, transit-ticket compatibility, or final unit photographs as reusable documentation.
SourceThe maker lists a regulated 3.3 V supply powered by two AAA batteries. It does not identify battery chemistry/brand, holder, polarity protection, regulator, current draw, runtime, charging behavior, voltage limits, thermal behavior, transport guidance, certification, or safety documentation.
SourceThe maker page says preorders are sold out and may have a few extras to trade in person. The current payload marks its $65 base, $150 Laser* Tag bundle, and $80 voluntary-extra-payment options unavailable. This is a current storefront snapshot, not proof of a sale count, physical inventory, finished build, payment, trade, pickup, delivery, refund, or post-event support outcome.
SourceOperational history
The catalogue preserves the seller's limited power/SAO statements without treating them as safe-use instructions, universal host compatibility, a battery-safety endorsement, or an electrical specification.
The dossier keeps the stated feature set intentionally narrow and does not promote it into a final reproducible engineering design or a manufacturing-quality claim.
The record describes the maker-published audio/storage intent without asserting reproducible firmware, media-reuse rights, final playback behavior, or user-operation instructions.
The catalogue treats this as an independent themed badge, not a transit artifact, fare instrument, official DEF CON credential, admission item, or sponsored product.
The record remains source-backed and image-free rather than copying Shopify photos/video frames, the Reddit preview, social-media material, screenshots, placeholders, or generated approximations.
The catalogue records a live sold-out and pickup-oriented source state without turning it into a confirmed fulfilled run or a guaranteed opportunity to acquire an extra.
