Issue dossier
The product and source describe channel monitoring, packet counting, access-point selection, and RSSI-based foxhunting, while the sketch enables ESP32 promiscuous mode and scans nearby networks. Sources do not establish user authorization, venue policy, consent, lawful-use boundaries, packet payload handling, metadata retention, encryption handling, target verification, false-positive behavior, tracking accuracy, interference impact, RF performance, privacy notice, security review, or responsible-use guidance.
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.

first-party maker storefront listing
HackMy*'s public product page labels GigaGeiger a Wi-Fi badge for DEF CON 33, shows the USD 120 listing and sold-out-since-August 6, 2025 state, describes its dial-selected monitoring, foxhunt, and web-flashing modes, and says it shipped with a lanyard and batteries. Storefront images are not used because the page does not state reusable image permission.
Badge: GigaGeiger Badge (DEF CON 33)
public Arduino/C++ implementation source
Published source for the ESP32-S3 GC9A01 display setup, rotary input, Wi-Fi scans, promiscuous-mode packet counter, BSSID/RSSI foxhunt, and local web-update code. It exposes one reviewed implementation rather than a signed or supported release, a security review, traffic-capture authorization, or a guarantee of shipped-firmware parity.

public PCBWay fabrication project
A June 25, 2025 PCBWay project by Matt Wagner titled GigaGeiger PCB, described as PCB for the DEFCON GigaGeiger badge and offering Gerbers under the page's CC BY-SA label. Its separate project attribution and license do not establish storefront fulfillment, repository-wide licensing, final board parity, or image publication provenance.
Badge: GigaGeiger Badge (DEF CON 33)
public maker-linked firmware and fabrication repository
The source repository linked directly by the maker storefront contains the GigaGeiger README, Arduino sketch, ESP32-S3 build outputs, Gerber archive, enclosure STL files, asset images, and a root MIT license. It is a public development and fabrication trail, not proof that every file or build matches every sold unit, nor a selected rights-cleared hero image.

GitHub / Penzz-HM · retrieved 2026-05-15
Primary implementation source for the GC9A01 display pins, rotary-input pin, packet-count callback, Wi-Fi scanning, BSSID/RSSI tracking, ESP32 promiscuous mode, and local web update server. In the reviewed sketch the callback increments packets only, while a displayed Deauths count is not populated by deauthentication parsing. It does not establish a release tag, security review, traffic-capture permission, or shipped-unit behavior.

Primary public repository source for the GigaGeiger README, Arduino/C++ sketch, ESP32-S3 build outputs, Gerber archive, STL enclosure files, and root MIT license. It describes the implementation and source scope but does not prove final manufacturing, component population, deployment, update safety, or that every repository image is suitable for independent local publication.

Primary maker storefront source for the DEF CON 33 Wi-Fi-badge label, USD 120 price, sold-out-since-August 6, 2025 state, Geiger-counter framing, three dial-selected modes, lanyard/battery statement, and direct links to source/documentation/design material. It does not establish official DEF CON issuance, event delivery, an electrical specification, radio authorization, or image reuse rights.

Primary public fabrication-source page dated June 25, 2025 for a GigaGeiger PCB described as a DEFCON GigaGeiger badge board, with a Gerber-download surface and a CC BY-SA label. It is retained as a separately attributed source and does not by itself prove maker identity, production quantity, final revision, storefront fulfillment, repository license scope, or reusable hero-image provenance.
