Ring light for ESP32-Cam Case

I wanted to install fuchsr's remix of the popular ESP32-CAM Case (initially designed by bkgoodman) … but I needed a stronger light. So I bought one of the 12 LED neopixel ring lights from Aliexpress and designed this holder, that glues to the original case. The three wires can be threaded through the original flash LED hole.

Can be printed facing down - if bridges sag, needs a little cleanup before glueing the LED ring to the holder.

====================

I'll try to explain how I changed the “original Prusa camera firmware" for ESP32-CAM for the AI-Thinker module to light the Neopixel ring. Do this at your own risk - and NO, I can't put this on GitHub as a fork because I do know how to code - but I never used GitHub or anything similar and I'm not going to learn how to do it just for this project ;)

Firmware source - this worked for me on December 28th, 2024

NeoPixel data pin must be connected to pin 13 of the ESP32 board. Connecting an external temperature/humidity sensor will NOT be possible anymore. Light will be permanently on in a dimmed state and will light up at 100% for the configured flash time. 

camera.h

After the existing #include lines, add
#include <Adafruit_NeoPixel.h>

camera.cpp

In the definitions, after
Camera SystemCamera(&SystemConfig, &SystemLog, FLASH_GPIO_NUM);
insert
Adafruit_NeoPixel neostrip = Adafruit_NeoPixel(12, FLASH_NEOPIXEL_LED_PIN, NEO_RGB + NEO_KHZ800);

In Camera::Init, after
  InitCameraModule();
  ApplyCameraCfg();
  GetCameraModel();
insert
  neostrip.begin();
  neostrip.setBrightness(100);
  neostrip.show();

In Camera::SetFlashStatus, after 
/* rgbLedWrite control of the FLASH */
change code to 
#if (true == CAMERA_FLASH_NEOPIXEL)
  if (true == i_data) {
    for(int i_px=0; i_px<12; i_px++)
      neostrip.setPixelColor(i_px, FLASH_ON_STATUS, FLASH_ON_STATUS, FLASH_ON_STATUS*0.45);
  } else if (false == i_data) {
    for(int i_px=0; i_px<12; i_px++)
      neostrip.setPixelColor(i_px, FLASH_OFF_STATUS, FLASH_OFF_STATUS, FLASH_OFF_STATUS*0.25);
  }
  neostrip.show();
#endif
