CSIDES 2025 Crab Badge
ATtiny1614 infrared-capable electronic crab badge
A completed CSIDES 2025 electronic PCB badge created by the event's badge sponsor, Punk Security. The organizer's sources and Eventbrite listing establish the October 3 Grand Pier community cybersecurity conference in Weston-super-Mare; Punk Security's own event page calls it the custom badge sponsor and identifies an infrared-capable badge. Its post-event public repository identifies the crab badge, preserves board, schematic, Gerber, firmware, and artwork material, and names an ATtiny1614, buttons, two CR2032 clips, 5050 NeoPixel, trimmer, capacitor, transistor, and 940 nm infrared LEDs. The sources do not establish a production quantity, attendee allocation, individual handoff, final unit-by-unit configuration, electrical-safety result, device-interaction outcome, or reusable image provenance.
