SourceThe qwiic/STEMMA QT compatible port gives the badge a plug-in sensor ecosystem for post-event use and experiments.
SourceThe 2016 badge was explicitly inspired by Mitch Altman's TV-B-Gone and preserved a TV-B-Gone-style app path in the Arduino badge concept.
SourceJohn Thurmond's LED Filament hexpansion appears in the official showcase as a rainbow LED-filament add-on, extending Tildagon's visual display culture beyond the onboard LEDs.
SourceChris's neopixel_rave drives WS2812/NeoPixels from TiDAL, with Hatchery notes about torch-LED data wiring, level-shifting constraints, and external 5V/power-bank needs.
SourceMatt Emerick-Law's EEH Logo app controls NeoPixels on the East Essex Hackspace LED Logo Hexpansion and advertises that the hexpansion is expected to be available at EMF 2026.
SourceMatt Emerick-Law's Pacman LED app controls LEDs on the Pacman hexpansion created by The Untitled Goose, capturing another app-store entry tied to a named physical add-on.
SourceThe badge uses 18 WS2812B-MINI-V3 addressable LEDs, with firmware described as giving a traffic-light-style indication for air-quality state.
SourceThe public pinout and firmware define 32 WS2812B / NeoPixel LEDs on IO21, with firmware files dedicated to pixel behavior.
SourceThe official badge page and manual document a Raspberry Pi Zero W at the center of the badge, paired with a custom SAINTCON board and badge image.
SourceThe second badge is documented around a VoCore/RT5350F module running OpenWRT with Wi-Fi, two Ethernet ports, USB host/storage goals, and heatsink work.
SourceThe project page says the ToorCon 14 badge used the same radio circuit as the IM-Me, turning IM-Me-style firmware customization into a USB badge workflow.
SourceThe product page and pinout describe two CC1101 modules, and the firmware maps separate A/B CC1101 SPI and GDO0 pins around a default 433.92 MHz RF workflow.
SourceThe antenna guide documented temporary human/copper-wire reception tricks and the proper SMA modification, including rotating or bridging the 0-ohm resistor in the RF path.
SourceThe README documents a CC1101 radio at 433 MHz, Fox Hunting RSSI behavior, and Friends RF peer-to-peer profile exchange with non-volatile history.
