LayerOne 2019 Voight-Kampff Badge

ATtiny2313 Blade Runner badge with ESP32CAM add-on path

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.

Why It Mattered

It fills the LayerOne gap between the 2018 ESP32 audio badge and the 2023 PIC HID return, preserving a year where the base badge stayed deliberately simple while the add-on ecosystem carried richer narrative and sensing behavior.

Hardware

Hackaday documents an ATtiny2313 main badge with 16 RGB LEDs and six surface-mount buttons; the back exposes six solder jumpers for persistent state, plus a five-pin add-on header providing power, PWM, and I2C. The article shows add-on examples including an ESP32CAM eye module, a hobby-servo eye mechanism, and additional LED behavior.

Software & Apps

The public CharlieX repository preserves the LayerOne 2019 badge source trail, including ATtiny badge code and ESP32CAM add-on material. Hackaday frames the ESP32CAM add-on as the Voight-Kampff-style test surface, while the main badge itself remains a small LED/button controller rather than a Wi-Fi badge core.

Lore

The badge asked attendees to hunt replicants through a Blade Runner theme. Hackaday says the ESP32CAM add-on takes a photo and uses face recognition to classify the wearer as human or replicant, while other add-ons extend the eye/LED behavior from the same five-pin expansion header.

Issues & Camp Impact

add-on scope caveat note

The ESP32CAM face-recognition behavior belongs to an optional add-on path, while the base badge is documented as an ATtiny2313 LED/button board.

The catalogue avoids implying that every 2019 badge had an onboard camera, Wi-Fi-capable core, or face-recognition hardware.

Confidence: event report
Status: documented
Timeframe: LayerOne 2019 badge and add-ons
Source note: Hackaday LayerOne 2019 badge report and charlie-x/layerOne2019 source trail.

hardware-media rights caveat note

Visible Hackaday, official, and repository-linked media prove the badge and add-on context, but no specific LayerOne 2019 badge photo or full upstream raster has been paired with complete reusable image license or permission, attribution, source URL, and processing notes.

The entry remains source-backed and image-free rather than copying article photos, event media, repository screenshots, or project images without full provenance.

Confidence: local project policy
Status: documented
Timeframe: current catalogue build
Source note: badge.gallery image policy, LayerOne HHV page, Hackaday article media, and charlie-x/layerOne2019 repository media.

missing rights-cleared image note

No LayerOne 2019 Voight-Kampff Badge image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.

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.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy and LayerOne 2019 HHV, InfoconDB, Hackaday, and CharlieX repository source trail.

source-depth caveat note

The public sources prove the ATtiny2313 main badge, repository source trail, and ESP32CAM/servo add-on context, but this pass did not recover a complete final schematic, BOM, production package, firmware release tag, or challenge solve archive.

The record keeps hardware, software, and add-on statements tied to public evidence while avoiding unsupported production-scale and final-firmware claims.

Confidence: source-backed but incomplete
Status: needs deeper artifact inventory
Timeframe: current catalogue build
Source note: LayerOne HHV archive, Hackaday event report, and CharlieX layerOne2019 repository.
