Issue dossier
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
The shipped production boards include reverse-battery protection; earlier prototype boards may lack it. The account is the designer's own and is not independently audited.
Evidence
Attendee Lua raycasting shooter built against the badge's documented sandbox APIs, confirming the stock Lua app sandbox and public badge API surface.
Attendee Hack the North 2026 badge app for creating 12x12 colored images, further corroborating the hackable badge platform distributed at the event.
Attendee ESP-IDF replacement firmware describing the badge hardware: ESP32-C3, 320x240 ST7789 display, eight buttons, SC7A20 accelerometer, WS2812B LEDs, stock Lua sandbox, and ESP-NOW peer-to-peer messaging.
GPL-3.0 community project created October 19, 2026 that turns the badge into a standalone Game Boy Color handheld running Pokémon Crystal on a Peanut-GB fork, with asynchronous LCD DMA, flash saves, USB diagnostics, and game-driven RGB LEDs, tested on a physical badge. It does not include the game ROM.

Nick Ficara's October 13, 2026 first-hand account of the badge project from a January pitch through EVT, DVT, PVT, and the production run at JLCPCB: 1,750 populated badges for hackers plus 750 blank boards for volunteers, about 20,300 USD in total, the design errors found at each stage, the overnight preparation, and usage and survey figures from the event.
Hackaday post by Jenny List, October 16, 2026, summarising the designer writeup: 1,750 badges, wrong footprints, misplaced components, power-supply issues, and rotated parts fixed before delivery, and badges that were well received and well used at the event.
Browser IDE linked from the official firmware README for installing Lua apps on the badge over USB without reflashing firmware.
Opening-ceremony manual covering AA power, button layout, the boot QR code used for check-ins and food, sticker scanning, badge bumping in the Connect app, sync stations at the Badge Help Desk, the Solana hunt, the Saturday Badge Workshop, care, and battery and heat safety.
Official Devpost page for the September 18-20, 2026 invite-only 36-hour hackathon at the University of Waterloo, with QR-coded attendee badge IDs in the submission rules and the Solana Best Badge Hack prize inviting attendees to build something creative with their Hack the North badge.
