Cloth Hall Court, Quebec Street, Leeds · United Kingdom · 2026
An official UK BSides Leeds 2026 badge documented by the punk-security repository as an ATtiny814 Artie the Owl board with eighteen SK6812 addressable RGB side-emitting LEDs, six capacitive touch pads, two CR2032 coin cells, and three single-player games whose one-byte EEPROM unlock gates hidden bonus LED animations, for the June 13, 2026 seventh edition at Cloth Hall Court in Leeds.
Lifecycle
A one-byte EEPROM state byte at address 0 gates three hidden bonus LED animations, each unlocked by winning one of three single-player games (Stop The Light, Follow The Sequence, Find The Sequence), with matching two-player variants.
The firmware includes a nine-minute countdown timer mode usable as a practical con timer, alongside Knight Rider, breath, spin, and looping-eye animation modes.
The BOM documents eighteen SK6812 addressable RGB side-emitting LEDs arranged nine per eye and six capacitive touch pads on the ATtiny814 board.
