Cat feeder servo Motor upgrade

This weekend I upgraded our Cat feeder from the Parallax continuous rotation servo motor to the more powerful and faster PowerHD continuous rotation servo from Pololu bought during their black friday sale.

Also used the opportunity to wash and clean up the Zevro KCH-06138 dry-food dispenser.

The servo coupler, mount, hubs, gears, plastic link chain, misc. hardware was sourced from ServoCity and my local hardware store.

The arduino Diavolino and chronodot came from EMSL, the bluefruit from adafruit, and other stuff from seeedstudio, mouser etc.

Thing still left to try out:

  1. Reduce the serving size
  2. Better SW debouncing the rotary encoder
  3. Test and check with larger quantities of food
