Badges
PSoC4 blinky badge and VoCore OpenWRT network badge
LayerOne 2015's badge effort produced two electronic badge designs documented by the official Hardware Hacking Village archive and CharlieX's Hackaday.io project: a battery-powered PSoC4, ESP8266, and WS2812B blinky badge plus a VoCore/RT5350F OpenWRT network badge with Wi-Fi and dual Ethernet intent.
PSoC4 and ESP8266 badge with 20 WS2812B LEDs
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.
STM32F4 badge for CAN bus and vehicle-hacking experiments
LayerOne 2017's electronic badge was a CAN-bus-focused STM32F4 conference badge with a TFT display, storage, USB device and host behavior, external CAN headers, audio output, rechargeable battery planning, PC-side CAN tooling, and J2534-adjacent software work.
ESP32-WROOM-32 audio badge with Alexa experiment path
LayerOne 2018's electronic badge was an ESP32-WROOM-32-based audio and network badge documented by the official HHV archive, Hackaday's event report, the linked CharlieX ESP32_Alexa repository, and mmca's public hardware notes.
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.
PIC16F1455 USB keyboard badge with addressable LEDs
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.
ATTiny4313 POV fidget-spinner badge
The LayerOne 2024 POV Spinner Badge was an electronic fidget-spinner conference badge that displayed words and patterns through a 12-LED persistence-of-vision strip while spinning.
RP2040 and iCE40 glitching badge for hardware hacking
LayerOne 2025's GLiTCh BadgE was a conference electronic badge and hardware-hacking platform centered on an RP2040, iCE40 FPGA, voltage glitching, crowbar control, SWD, AVRISP, analog monitoring, multiple USB modes, and CLI-driven experiments.
