WOPR Summit 0x00 Badge

ATtiny841 soldering badge with colored and RGB LEDs

The WOPR Summit 0x00 badge was an attendee-assembled electronic badge for the inaugural Atlantic City conference. Hackaday documents a WarGames/WOPR-inspired board with a dozen colored LEDs, eight RGB LEDs, through-hole LEDs and resistors, battery holders, and an ATtiny841 controller, while Russell Handorf's build guide preserves the soldering and staff-flashing workflow.

Why It Mattered

It adds an East Coast hardware-and-security conference badge lineage where the badge was deliberately entry-level: attendees learned by placing LEDs, soldering a surface-mount ATtiny841, debugging with peers, and getting firmware flashed by event staff.

Hardware

Public sources describe an ATtiny841-based badge with through-hole resistors, user-selectable colored LEDs, RGB LEDs, battery clips/holders, and mixed through-hole plus surface-mount construction. The build guide specifically calls out ATTINY841-SSU placement, resistor soldering, RGB LED polarity, colored LED voltage/polarity choices, and battery-clip orientation.

Software & Apps

Hackaday reports that assembled badges were flashed by an event volunteer, while Handorf's guide says staff loaded firmware at the info booth. No public firmware repository, pin map, binary release, or challenge-source archive was recovered in this pass.

Lore

The badge intentionally echoed the WOPR computer from WarGames and turned assembly into a social first-day activity in the open hacking area. Hackaday later notes that Russell Handorf and Mike Kershaw were WOPR Summit's official badge guys and used the badge as a teaching example during the `Strategies for your Projects: Concept to Prototype` hardware workshop.

Lifecycle

Add-ons & Upgrades

assembly workflow documented

Attendee soldering workflow

Attendees assembled their badges at soldering stations with peer help and minimal official guidance before staff flashed firmware.

Issues & Camp Impact

firmware-source gap note

The public record proves staff firmware flashing after attendee assembly, but this pass did not recover a public firmware repository, binary release, pin map, bootloader workflow, or badge-challenge source archive.

The software section records the verified staff-flashing workflow without inventing firmware behavior or challenge internals.

Confidence: source-backed but incomplete
Status: needs archive recovery
Timeframe: current WOPR 0x00 pass
Source note: Hackaday WOPR Summit field report and Russell Handorf WOPR 0x00 build guide.

image-rights boundary note

Hackaday and Handorf publish real badge photos and build images, but this pass did not recover complete reusable image rights, attribution, source URL, and processing notes for local catalogue publication.

The record remains source-backed and image-free rather than copying article or build-guide media without a clear reuse basis.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current WOPR 0x00 pass
Source note: badge.gallery image policy, Hackaday field-report media, Hackaday workshop media, and Handorf build-guide photos.

missing rights-cleared image note

No WOPR Summit 0x00 Badge 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.

The United States record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy and Hackaday WOPR Summit field report, Russell Handorf first-hand build guide, Hackaday hardware-workshop writeup, and WOPR Summit official archive trail.
