Build Details
3 AAA battery pack too large, therefore a single and double battery pack wired together to accommodate space issues. Coffin walls carved out to accommodate board.
Project Surprises:
GPIO02 boot-up tests for PSRAM voltage requirement interfered with HSPI Bus usage. Requires eFuse setting to voltage PSRAM voltage level for HSPI normal operation ESP32 Cam with AI-Thinker hardware setup can be used for the project with a simple pin assignment change. An overly elaborate method for using a vibrating motor to trigger SFX module, isolating the module electrically from Microcontroller abandon due to unnecessary complexity and stray triggering from handling project. SFX module uses High Brightness LEDs that cause short bursts of high current that have to be handles by separate battery pack in order to not require additional power supply circuitry for a common power supply. I had a ICR18650 lying around, so battery operation of project utilizing built in charging of the ArduCam. Then again, it could be a self-destruct method.
Programming Elements
TFT display for the ArduCam HSPI usage Facial Detection Code Simple RAW Image decoding for saved images Camera image buffer display to TFT display
