Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The first-hand making-of post documents an ESP32 badge with 1.3-inch 240x240 IPS colour display, custom PCB, touch buttons, 18650 battery, and 3D-printed case.
Badge context
Public GPL-3.0 GitHub repository preserving the badge firmware, prebuilt ESP32 binary, assets, platform code, demos, games, OTA code, WiFi scanner, Bluetooth material, SDL tooling, and Arduino/ESP32 build instructions.
Tony Mamacos first-hand post documenting the 2019 badge hardware, ESP32 processor, colour IPS display, touch buttons, 18650 battery, 3D-printed case, firmware architecture, game content, WiFi high-score flow, Bluetooth controller experiment, and post-event lessons.
Hackster project noting that the author ran the ESP32 TV-output experiment on a BSides Cape Town 2019 badge and pointing to the original badge software writeup.
Third-party writeup identifying the 2019 badge core as ESP32-WROOM-32U and explaining why it was suitable for C# NanoFramework experiments.
