Why It Mattered

It adds an Abu Dhabi HITB+CyberWeek badge artifact to the Asian/Middle East lineage and preserves a real Packet Hack Village wearable badge without copying uncleared Hackster or GitHub images.

Hardware

The public sources document a wearable PCB badge with UAE skyline and mech artwork, an OLED display, right-side binary-entry keys, S1/S2 controls, male programming headers and pinout markings, Rx/Tx serial pins, wrist-wearable framing, and AVR/ISP reprogramming workflow. The exact MCU package, schematic, BOM, board files, and production quantity were not recovered in this pass.

Software & Apps

The GitHub firmware archive builds with AVR tooling and avrdude, supports per-handle flashing through `make HANDLE=...`, initializes TWI and OLED display code, shows Packet Hack and HITB imagery, and enters a CTF binary-code input mode from the S1 switch. The Hackster writeup also documents custom font/animation libraries, serial-code hooks, and a flash script refined by lanrat.

Lore

The Hackster project frames it as the first Packet Hack Badge for HITB+CyberWeek, with UAE skyline/mech art, a Packet Hack CTF challenge, reprogramming pins, and wrist wearability for the Abu Dhabi event.

Lifecycle

Add-ons & Upgrades

badge customization source-backed

Handle personalization and serial hooks

The README documents `make HANDLE=...` personalization, and the Hackster writeup describes lanrat's quick script for flashing usernames plus serial communication hooks tied to Rx/Tx pins.

Compatibility: HITB+CyberWeek 2021 Packet Hack Badge

badge puzzle mode source-backed

Packet Hack CTF binary-input mode

The Hackster writeup says holding S1 launches Insert Code mode, where right-side keys enter a Packet Hack CTF binary value and S2 clears input.

firmware behavior source-backed

AVR OLED display firmware loop

The public firmware initializes TWI and OLED display handling, personalizes a handle, and cycles Packet Hack and HITB imagery on the badge.

Compatibility: HITB+CyberWeek 2021 Packet Hack Badge

firmware workflow source-backed

ISP reprogramming and pinout path

The project documents male headers, pinouts, jumper wires, ISP programmer use, Microchip Studio / AVR toolchain builds, avrdude flashing, and fuse recipes.

Operational history

Issues & Camp Impact

distribution scope caveat note

The public badge sources tie the Packet Hack Badge to HITB+CyberWeek and Packet Hack Village, but do not document exact attendee eligibility, distribution count, or whether it was issued to all conference attendees.

The record is treated as a Packet Hack Village / HITB+CyberWeek artifact rather than a universal admission credential.

Confidence: artifact source but incomplete event logistics
Status: documented source limitation
Timeframe: November 2021 HITB+CyberWeek
Source note: Hackster Packet Hack Badge project and HITB+CyberWeek event sources.

hardware archive gap note

The recovered sources document the wearable badge, OLED, controls, headers, pinouts, AVR/ISP flashing, firmware behavior, and CTF mode, but this pass did not recover a schematic, BOM, board files, exact MCU package, or production quantity.

The record stays at source-backed hardware surfaces and avoids unsupported component-level claims.

Confidence: source-backed but incomplete
Status: needs schematic or BOM recovery
Timeframe: 2021 badge archive pass
Source note: Hackster Packet Hack Badge project and GitHub firmware repository.

missing rights-cleared image note

No local Packet Hack Badge image has been added because the Hackster project images and GitHub README image have not been paired with a reusable image license, attribution, and processing notes for publication.

The entry remains source-backed and image-free rather than copying Hackster or GitHub-hosted media, screenshots, or generated placeholder art.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy, Hackster project page, and Packet Hack Village GitHub repository.

repository license caveat note

The public firmware repository has no detected repository license, so code and repository imagery are cited as evidence but not copied or republished as local badge assets.

The catalogue can document firmware behavior while avoiding unsupported reuse claims for source or media.

Confidence: GitHub API and repository audit
Status: needs explicit license
Timeframe: current catalogue build
Source note: lanrat/PacketHackVillageHitBBadge2021 repository and GitHub metadata.
