BSides Brisbane 2026 Clock Module Badge

Post-event 555/74LS clock-generator badge with MIT source release

BSides Brisbane 2026's official prospectus offered electronic badge design/build for 500 delegates, Humanitix marked the July 4 event passed while listing conference-badge and VIP special-badge pickup, and public event updates named BLARGE as the electronic-badge supporter. Six days after the event, the `bsidesbrisbane/badge-2026` repository publicly documented the actual 2026 Clock Module: a photographed purple BSides Brisbane board in a 3D-printed case, a simple manually controllable clock generator made from 555 timers and 74LS-series logic, with committed Gerbers, BOM/CPL production data, an STL case file, and an MIT license.

BSides Cleveland 2026 Cassette Badge

Discrete-logic cassette LED badge with attendee play and volunteer rewind variants

The BSides Cleveland 2026 conference badge, published by the organizers on October 6, 2026 as CC0 KiCad designs: a cassette-tape-shaped, all-SMD coin-cell board in two variants. A Schmitt-trigger oscillator clocks a 74HC4017 decade counter that steps rings of orange, green, and blue LEDs, so the attendee cassette appears to play and the volunteer cassette appears to rewind. The back artwork hides a Vigenère-and-ROT13 easter egg that decodes to Hack The Planet. The September 26 event is officially completed, but no source gives a badge count or describes the handoff.
