Greycademy 2026 Hackbadge

Source-backed CH32V003 student-bootcamp electronic badge

Hackin7's public project page identifies a deployed electronic PCB Hackbadge created for Greycademy 2026. NUS Greyhats' official announcement says program participants could take home electronic badges, while the primary maker record identifies a CH32V003 coin-cell design and reports an event-day power-reliability repair across more than 200 programmed units. The public trail does not define every recipient, final firmware image, or all-unit configuration.

Why It Mattered

It adds a real current Singapore student-security bootcamp artifact rather than treating an event swag promise as proof of electronics. The record also preserves a narrow first-person production reliability account without turning it into generic guidance or a claim about every final badge.

Hardware

The primary maker account identifies a CH32V003 microcontroller and coin-cell power, and describes the Hackbadge as a simple, low-cost badge with artwork by the maker and PCB design by Howard Ong. No public schematic, PCB file, bill of materials, board revision, coin-cell type, LED/display/input inventory, connector/pinout, safety record, manufacturing file, or final unit photograph with reusable rights has been recovered.

Software & Apps

The maker reports that the initially programmed units could brown out on their coin cells and that more than 200 already programmed badges were reprogrammed before distribution to improve battery life. The public sources do not publish the firmware, binary, repository, exact configuration change, release, build path, provisioning record, final image, or proof that every unit received the same correction, so the catalogue does not reproduce implementation instructions.

Lore

A.YCEP × Greycademy was a NUS Greyhats program for tertiary students, combining workshops, practice, and CTF qualification/finals. Its official announcement listed electronic badges among take-home goodies; the maker's deployed-project record connects the physical Hackbadge to that program. This supports an event-specific electronic artifact, not an admission credential, a universal entitlement, or an official hardware release.

CH32V003 coin-cell badge core

The primary maker account identifies a CH32V003 controller and coin-cell power for the Greycademy Hackbadge. It does not identify the exact cell type, power circuit, components, display, input/output surface, connector, pinout, safety validation, or final-unit configuration.

Post-deployment power reliability repair

The maker reports an early coin-cell brownout issue and says more than 200 already programmed badges were reprogrammed before distribution to improve battery life. This records a bounded field-repair history, not a released firmware, recipe, full validation result, or proof of universal final-unit parity.

Operational history

Issues & Camp Impact

coin-cell brownout and field-repair history warning

The maker reports that the original coin-cell setup could brown out after roughly two minutes, then says more than 200 already programmed badges were reprogrammed before distribution and informally appeared to have substantially improved battery life. The source does not provide a controlled test, exact firmware change, affected-unit count, serial/revision mapping, battery characterization, follow-up failure rate, or confirmation that every distributed unit received the repair.

The record keeps an attributable production/reliability history visible without offering repair instructions, declaring the hardware safe, or generalizing a maker observation into a verified universal outcome.

The public trail identifies a CH32V003, coin-cell basis, maker artwork, and Howard Ong PCB design, but no schematic, PCB file, bill of materials, part list, board revision, firmware repository, binary, source license, build/provisioning path, release, final configuration, manufacturing record, or all-unit parity evidence was recovered.

The badge record remains limited to the organizer wording and maker's high-level factual account rather than inventing technical details or treating a repaired field unit as a fully published hardware release.

No Greycademy 2026 Hackbadge image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.

NUS Greyhats' official announcement says participants could take home electronic badges, and the maker says the Hackbadge was intended for Greycademy participants. Neither source publishes a recipient list, ticket/registration mapping, quantity, pickup record, allocation rule, official credential role, access-control function, or delivery ledger for this specific badge.
