Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
After WiFi connection, the badge connected to an MQTT server, subscribed to an event topic, and displayed current talk details on the OLED.
Badge context
Primary project writeup documenting the limited run, ESP8266/OLED hardware, Arduino/MQTT software, hand-built construction, costs, challenges, and future badge plan.
Repository slide deck for Chrispus Kamau's badge-making talk, documenting ESP8266-01, 0.96-inch OLED, LEDs, 600 mAh LiPo plan, Arduino/MQTT software, paperboard construction, production cost, and next-badge goals.
Public GitHub repository for the AH 2017 conference badge Arduino code and related materials.
Source trail
Primary author source for the AfricaHackOn 2017 limited-run badge, ESP8266/OLED hardware, MQTT schedule display, production constraints, and future badge-culture goals.
