BSides Cheltenham 2023 Delorean Badge
ATtiny402 DeLorean PCB-art conference badge
An electronic PCB-art conference badge documented by its maker and badge sponsor, Punk Security, for BSides Cheltenham 2023. Punk Security's own dated event listing identifies its June 3 Cheltenham appearance as that year's badge-sponsor engagement, names a talk on building the BSides Delorean badges, and describes them as functional conference badges. The public `bsides-cheltenham-2023-badge` repository calls the artifact the Delorean badge, reports that parts sold for badge completion on the day raised more than £300 for Mind, and preserves EAGLE, Gerber, library, and Arduino firmware material. Its parts list names an ATtiny402, button, CR2032 clip, NeoPixel, and 3528 blue LED. The reviewed sources do not establish organizer-side 2023 confirmation, venue, production quantity, attendee allocation, individual handoff, final unit-by-unit configuration, completed assembly count, safety validation, or reusable image provenance.
