LayerOne
The May 24-26, 2019 LayerOne Pasadena edition whose official Hardware Hacking Village archive, Hackaday report, and CharlieX repository document a Blade Runner / Voight-Kampff electronic conference badge and add-on kits.
Pasadena Hilton, Pasadena, California · United States · 2019
LayerOne 2019's electronic badge used a Blade Runner / Voight-Kampff theme around a small ATtiny2313 LED-and-button badge, with Hackaday documenting optional add-on boards including an ESP32CAM eye/face-recognition module for the badge's test-of-humanity behavior.
Lifecycle
Hackaday frames the ESP32CAM eye add-on as the camera and face-recognition surface for the Voight-Kampff human-or-replicant test.
The article shows a hobby-servo eye add-on as one of the mechanical extensions for the badge's add-on header.
Hackaday describes the base LayerOne 2019 badge as a small ATtiny2313 board rather than an ESP32 badge core.
Hackaday documents a five-pin add-on header carrying power, PWM, and I2C for the 2019 badge's expansion boards.
The public CharlieX repository preserves ATtiny source material for the badge and documents ESP32 camera-board firmware context without treating the camera board as the main badge controller.
The report documents six surface-mount buttons and 16 RGB LEDs on the main badge face.
Operational history
The catalogue avoids implying that every 2019 badge had an onboard camera, Wi-Fi-capable core, or face-recognition hardware.
The entry remains source-backed and image-free rather than copying article photos, event media, repository screenshots, or project images without full provenance.
The United States record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
The record keeps hardware, software, and add-on statements tied to public evidence while avoiding unsupported production-scale and final-firmware claims.
