Cape Town · South Africa · 2019
BSides Cape Town 2019's badge was an ESP32 electronic badge with a 1.3-inch 240x240 IPS colour display, touch buttons, 18650 battery, custom PCB, 3D-printed case, Arduino/ESP32 firmware, local SDL debugging support, WiFi high-score sync, Bluetooth GamePad experiments, and a public GPL-3.0 firmware repository.
Lifecycle
Later writeups treated the 2019 badge as an ESP32-WROOM-32U board suitable for C# NanoFramework and ESP32 game/video experiments.
The making-of post documents a colour GameOn-derived firmware with menu, single-player game, raycaster, voxel landscape, high-score JSON/WiFi workflow, setup screens, achievements, and debug screens.
The public repository preserves the badge firmware, ESP32 binary, assets, Arduino build settings, TFT_eSPI configuration, SDL local-debug path, games, demos, OTA code, WiFi scanner, and Bluetooth material.
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.
Operational history
The entry can now describe the badge hardware and firmware from primary sources while avoiding unsupported board-layout, production-run, or image-reuse claims.
The catalogue keeps the record image-free while preserving the source-backed badge existence and ESP32 core.
