LayerOne
The May 27-28, 2023 LayerOne return-to-in-person edition whose official conference post, Hardware Hacking Village page, and public repository document the PIC16F1455 USB HID electronic badge.
Hilton Pasadena, Pasadena, California · United States · 2023
LayerOne 2023's electronic badge was a PIC16F1455 USB HID and keyboard badge with WS2812B/SK6812-style addressable LEDs, DFU update workflow, writable flash-backed macro behavior, and a badge-competition path around a partial RubberDucky 2.0 script interpreter.
Lifecycle
The README says a very partial RubberDucky 2.0 script interpreter is commented out in the code and tied to a single-prize badge competition.
The README names a PIC16F1455 badge core, and the firmware configures USB clocking, interrupts, generic HID, and keyboard HID behavior.
The USB descriptor and keyboard source expose a keyboard HID interface, scan-code conversion, report sending, and button-triggered output including the default `LayerOne 2023` string.
The README documents holding the button while plugging in USB for DFU mode, Zadig/WinUSB setup, dfu-util upload, 454hex2dfu conversion, and Pickit fallback programming if the bootloader is overwritten.
The host README and firmware document HID writes that stage data in RAM and commit it into flash for later keyboard/macro output.
The README names WS2812B/SK6812 LEDs, while the firmware maps RC3 as the WS2812 output and cycles color-wheel and slow-fade LED effects.
Operational history
The entry remains source-backed and image-free rather than copying official-page images, repository previews, article photos, or screenshots without complete provenance.
The record preserves the competition hook without overstating the completeness of the recovered challenge material.
The catalogue presents the badge as reflashable while preserving the practical recovery boundary for surviving units.
The record keeps hardware, USB, LED, and firmware statements tied to the recovered public repository while avoiding unsupported production-scale claims.
