LayerOne
The May 28-29, 2016 LayerOne edition whose official Hardware Hacking Village archive and CharlieX Hackaday.io project document a PSoC4, ESP8266, and WS2812B electronic conference badge.
Sheraton Gateway LAX, Los Angeles, California · United States · 2016
LayerOne 2016's electronic conference badge returned to the PSoC4, ESP8266, and WS2812B platform as a single LED badge with Wi-Fi working before the event, a mini prototyping area, exposed rails and I/O, and public build logs from CharlieX.
Lifecycle
The project description lists PSoC 4 as the controller for the 2016 badge platform.
The all-at-once log reports that the LEDs were being controlled from a PC over Wi-Fi after ESP8266 orientation, reset, GPIO, noisy-power, and capacitance debugging.
The project describes a mini prototyping area with 3.3 V rail, battery rail, and PSoC4 I/O broken out so attendees could add their own components.
The Wi-Fi and pick-and-place log documents CR123A cells and holders, diode validation, stencil-holder work, eight early hand-built badges, and pick-and-place setup six days before the conference.
The project description names a 5x4 WS2812B LED array, and the development log says the design uses 20 LEDs rather than the earlier 25-LED expectation.
The project says the ESP8266 worked before the conference and exposed GPIO connections to the PSoC4 so the chips could interact and the PSoC4 could reset the Wi-Fi module.
Operational history
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 catalogue records the source-backed architecture and build status while avoiding unsupported claims about every final shipped component, production quantity, or assembled variant.
Hardware and software claims remain tied to the public HHV page and Hackaday.io logs instead of treating planned source publication as recovered source.
