Add-on dossier
A linkable lifecycle record for hardware expansions, app ecosystems, firmware upgrades, cases, radio parts, and post-event badge experiments.
The badge boot flow displayed the conference title, scanned wireless networks, waited for a programmed network, connected, and displayed IP and network details.
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.
