Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
Hackaday and the build guide identify the reverse-side microcontroller as an ATtiny841 / ATTINY841-SSU.
Badge context
Hackaday source for the inaugural Atlantic City WOPR Summit, Bally's venue context, badge-hacking area, attendee assembly, ATtiny841, twelve colored LEDs, eight RGB LEDs, battery holders, and staff firmware flashing.
Russell Handorf source for WOPR 0x00 2019 badge assembly logistics, soldering-station workflow, ATTINY841-SSU placement, resistor/LED/battery-clip steps, LED color caveat, and info-booth firmware loading.
Hackaday source tying Russell Handorf and Mike Kershaw to the official badge work and documenting the badge as a simple, low-part-count hardware teaching example for the four-hour Concept to Prototype workshop.
Official WOPR archive trail for the 0x00 edition, talk/workshop context, and event-lineage source; current live DNS was intermittent during this pass, so badge facts are anchored to the reachable field report and first-hand build guide.
Source trail
Field-report source for the inaugural Atlantic City event, Bally's Casino venue context, open hacking area, badge-hacking section, LED counts, ATtiny841 controller, attendee assembly, and volunteer firmware flashing.
Workshop-report source for Russell Handorf and Mike Kershaw's official badge-guy attribution, low-part-count teaching-example framing, mixed through-hole and surface-mount construction, and Concept to Prototype workshop context.
First-hand badge-build guide source for the WOPR 0x00 2019 badge, soldering logistics, ATTINY841-SSU, resistors, RGB LEDs, colored LEDs, battery clips, color-mixing warning, and staff-loaded firmware.
Official event archive trail for the 0x00 edition and talk/workshop context; the current live hostname was intermittently unreachable from the local resolver during this pass.
