- The author describes creating a 'Banned Book Library' using a WiFi smart light bulb to host and share banned books via an open access point and web server.
- They selected Tasmota firmware on ESP32C3-based bulbs for local control, overcoming hardware limitations like limited 4MB storage by adjusting partition tables.
- After exploring microSD expansion and other bulbs, they focused on firmware customization using ESP-IDF and Arduino, implementing features like captive portal and admin controls.
- The final setup includes a web interface for accessing books, LED color control for stealth, and a custom safeboot partition for OTA updates, albeit with storage constraints.
- Future ideas include enhanced color control, mesh networking for distributed libraries, and more ESP32 projects due to their affordability and versatility.
