tl;dr: A hacker reflashed a cheap Tasmota-based WiFi smart bulb (ESP32-C3, 4MB flash) to host an open WiFi access point serving banned ebooks via a captive portal, intended as a discreet "digital dead drop" you could install in public. Key challenges included the tiny storage (solved by repartitioning flash to free up 2MB for books), writing a custom safeboot firmware to enable OTA updates without leaking WiFi credentials, and abandoning a microSD expansion idea because soldering destroyed the bulb. Future plans include RGB color matching and mesh networking between bulbs to share larger libraries.
