Rotatable 3D render of the tripod-mounted dual-ESP case:
- Case body with rounded corners and lid
- Stacked ESP32 + ESP8266 boards inside
- LED indicator, USB port, ventilation slots
- Tripod pole with C-clamp mount
- USB cables, screws, chip details
- Drag to rotate, scroll to zoom
- Open in any browser
Replaced GoPro-sleeve case design with simpler stand-mounted box:
- Case clips to tripod leg/stand pole (20-35mm diameter)
- No camera sleeve needed — case sits on the stand
- Powered by standard USB power bank (off-the-shelf)
- Holds ESP8266 + ESP32 stacked with UART wiring
- Cable ports for USB in/out, LED window, ventilation
Simplified BOM: ~1/node (down from 4), no buck converters needed
Complete rewrite of firmware into two dedicated boards per camera node:
ESP8266 (Camera Bridge):
- Connects ONLY to GoPro AP — polls status, sends over UART
- Zero network switching, zero MQTT
- HTTP GET /bacpac/SH for status, start/stop
- JSON-per-line UART protocol to ESP32
ESP32 (MQTT Bridge):
- Connects ONLY to travel router — MQTT to Pi hub
- Reads status from ESP8266 over UART2 (RX16/TX17)
- Auto-registration, heartbeat, command forwarding
- Zero camera communication
UART Protocol: JSON-per-line at 115200 8N1
ESP8266→ESP32: status/ack/pong/error
ESP32→ESP8266: cmd (start_recording/stop_recording/ping)
Hardware updates:
- BOM now includes both boards (~4/node)
- 3D case has stacked dual-board compartment
- UART wire channel between board recesses
- Shared 3.3V power rail for both boards
- GoPro Hero 3 sleeve with lens/screen/USB cutouts
- ESP32 D1 Mini electronics compartment (vented)
- LiPo battery compartment with velcro strap slots
- Bill of materials (~0 per camera node)
- Wiring diagram (LiPo → dual buck converters → ESP32 + GoPro)
- Field deployment workflow
