Compute Module 5 medical-AI badge
Biohacking Village's DEF CON 33 Distiller BHV badge was a CM5-based medical-AI badge built with SolaSec and PamirAI, combining local voice/chat interaction, e-ink UI, physical buttons, colored LEDs, battery power, and public BHV software branches.
NFC-updatable passive four-color e-paper developer-conference badge
Flutter & Friends' organizer-published conference-app source added a Friends Badge editor on August 30, 2025: users could select an image, preview it with dithering, and write it to the conference badge through NFC. The companion `friends_badge` package explicitly describes control of the Flutter & Friends e-paper conference badge, and its implemented target profile is a passive four-color e-paper device. The source-backed record establishes a real event-linked electronic artifact at the completed Stockholm conference, but does not establish that every attendee received one, that it served as admission, or what final physical units contained.
Maker-documented RP2040 e-ink/NFC game-jam badge
Kai Pereira's public archive identifies these as Overglade hackathon badges designed for the completed Singapore game jam. The device has an RP2040, passive NFC, an onboard e-ink driver, and an exposed ticket-shaped PCB with public KiCad and MicroPython source trees. Official Hack Club pages establish the event, but not a badge entitlement or all-recipient allocation.
