ESP32-CAM servo mount

thingiverse

I made this motorized mount for an ESP32 CAM that I use to check on my printer from another room, or to check on my cats when I'm away. The servo can be moved from the web interface. Code is an adaptation from https://github.com/easytarget/esp32-cam-webserver that can easily be made to integrate the command for the servo. There is a catch on how to allocate the timer, however. void servoSetup() { // Allow allocation of all timers //Use all remaining timers ESP32PWM::allocateTimer(8); ESP32PWM::allocateTimer(9); ESP32PWM::allocateTimer(10); ESP32PWM::allocateTimer(11); h_servo.setPeriodHertz(SERVO_PERIOD_HERTZ); h_servo.attach(H_SERVO_PIN, SERVO_MIN, SERVO_MAX); servoSetPosition(50, 'h'); ESP32PWM::allocateTimer(12); ESP32PWM::allocateTimer(13); ESP32PWM::allocateTimer(14); ESP32PWM::allocateTimer(15); v_servo.setPeriodHertz(SERVO_PERIOD_HERTZ); v_servo.attach(V_SERVO_PIN, SERVO_MIN, SERVO_MAX); servoSetPosition(50, 'v'); } I will try to provide the full code when I have time to finish improving the UI. This can be printed in PLA, as the ESP32 module is not enclosed so it does not overheat. I had to print most part at a 105% scalling to get the module to fit nice (and to cut some excess), but starting form the vertical mount the scaling can remain at 100%. The feet can be replaced by something smaller if needed. It doesn't need to be fixed to remain stable with the original feet. I used a hot glue gun to secure the ESP32-CAM module to the mount, and to join the servomotor to each axis. There is a space for a small breadboard to cable everything. Add some small decoupling capacitor on the power supply as suddent current draw from the servo can make the ESP32 reboot.
