Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The project page and retrospective document the move to ESP32-WROVER for WiFi/Bluetooth, external RAM, LULZCODE memory needs, and faster display/SD-card paths after the DC25 BMD-300 badge.
Badge context
Primary log documenting the command-line challenge, ESP-IDF console direction, UART/USB serial focus, village-themed hacking areas, and social challenge framing.
Secondary hands-on review corroborating ESP32-WROVER, WiFi/Bluetooth, mesh/botnet framing, GreenPAK button handling, IS31FL3736 LEDs, CP2102N USB, serial adventure behavior, and pre-event badge delivery.

Primary retrospective source for design goals, ESP32-WROVER selection, 220x176 display, SD-card and SPI tradeoffs, IS31FL3736 lighting, CP2102N serial, two-AA power, SAO work, B.E.N.D.E.R. results, and production lessons.
Project-owner Hackaday.io source for Wild West of IoT framing, DEF CON 26 date/location context, ESP32-WROVER component listing, team roster, and open hackable badge/dev-board purpose.
Primary log documenting LULZCODE as a LOLCODE-derived badge scripting layer for microcontroller peripheral control and explaining why the badge used ESP32-WROVER external SPI RAM.
