Overglade
The completed January 29-February 2, 2026 Hack Club game jam in Singapore. The retained official Overglade page describes its physical game-jam framing, and a current Hack Club page identifies a January 2026 Singapore Overglade that took place. Kai Pereira's public project archive explicitly calls its RP2040, e-ink, and NFC devices Overglade hackathon badges, while organizer allocation, final production variation, software deployment, licensing, and image rights remain bounded.

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.
Lifecycle
The public README identifies an onboard e-ink driver and describes the badge as visually displaying a configured name. It does not establish the exact final panel, update behavior, display contents, power state, accessibility behavior, or participant configuration used at the event.
The design journal describes a passive NFC tag and antenna receiving harvested energy, alongside I2C/control wiring intended for possible active-NFC customization. This preserves the layered NFC design concept without asserting a final attendee-unit NFC IC, protocol, provisioned data, reader behavior, access-control role, enabled active mode, deployment, safety certification, or privacy practice.
The public repository includes native KiCad schematic, PCB, project, and production-data files plus MicroPython-oriented configuration, main application, e-ink driver, and bitmap assets. The archive does not expose an explicit root repository licence, release, or proof that it matches every produced or participant-configured unit.
Operational history
The catalogue records a real event-specific maker artifact without treating it as a universal attendee benefit, official access credential, organizer-issued device, or complete production account.
The Singapore record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
The record cites public design material as evidence but remains image-free and does not republish event photos, repository previews, screenshots, artwork, or approximate/generated imagery.
Hardware and software descriptions remain tied to the public design archive rather than promoted to a fully known, uniform, deployed event build.
