Issue dossier
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
Hardware and software descriptions remain tied to the public design archive rather than promoted to a fully known, uniform, deployed event build.
Evidence
Public firmware directory containing configuration, e-ink driver, main application, and bitmap assets; it does not establish a signed or participant-wide final event image.
Kai Pereira's journal records USB-C, RP2040, e-ink SPI, passive NFC energy harvesting, intended active-NFC wiring, ticket geometry, exposed copper art, and KiCad production-file context.
Primary maker documentation identifying zero-power Overglade hackathon badges, RP2040, 4 MB flash, passive NFC, e-ink driver, breakout pins, ticket-shaped PCB, and MicroPython-oriented configuration.
Public PCB directory containing native KiCad schematic, PCB, project, and production-data files; it is technical evidence, not a confirmed final attendee-unit or image-reuse basis.
Retained official Hack Club Overglade page for the January 29-February 2 Singapore physical high-school game-jam framing. It does not define badge allocation, specifications, delivery, or media reuse rights.
Current official Hack Club page identifying Overglade as a four-day Singapore game jam for teens that took place in January 2026; it establishes completed-event context but not badge eligibility or technical details.
Kai Pereira's public project archive for Overglade hackathon badges, including its source-tree structure. The reviewed repository root did not expose an explicit licence file, so it is evidence rather than a blanket reuse grant.
Source trail
Current official Hack Club retrospective identifying Overglade as a January 2026 Singapore game jam that took place. It corroborates the completed event but does not document badge allocation, hardware, firmware, or media rights.
Primary official event source for the January 29-February 2 Singapore physical high-school game-jam framing and Hack Club organizer context. It does not state that a badge was included or who received one.
Primary maker-published source archive for an event-specific Overglade badge design and its PCB and firmware directories. The reviewed root did not expose an explicit repository licence or a reusable image basis.
Primary maker journal for USB-C, RP2040, boot/reset, e-ink SPI, passive NFC energy-harvesting, intended active-NFC control wiring, ticket-shaped PCB, exposed copper art, and native KiCad production-file context.
Primary badge-design source identifying zero-power hackathon badges for Overglade in Singapore and documenting the RP2040, 4 MB flash, passive NFC, e-ink driver, 20 GPIO breakouts, two-layer PCB, and MicroPython configuration framing.
