The CactusCon 2014 PCB badge is preserved through Eric / Robot Ambassador's first-hand writeup, which describes 300 event badges designed by Erik Wilson, given away at the HeatSync Labs booth, and assembled by attendees with LEDs, resistors, batteries, and acrylic hardware.
Lifecycle
HeatSync Labs brought acrylic backs, coin batteries, LEDs, resistors, and badge lanyards so attendees could solder a working LED badge at the booth.
The first-hand writeup says 300 CactusCon PCB badges were made and given away at the HeatSync Labs booth.
The badge outline was designed so the arms and legs could be broken out or used as LAN taps.
The writeup describes the badge head as a USB 3.0 breakout section.
The front and back of the badge left space intended for a Teensy expansion.
Operational history
The event edition is named by year and kept source-scoped rather than assigning an unsupported CactusCon edition number.
The entry remains source-backed and image-free rather than copying blog photos, social media, screenshots, or generated media.
The catalogue preserves the physical badge lineage while avoiding unsupported component-level or reproducibility claims.
