Motivation
MOTIVATION

  • Cats waking me up too early

  • Regular feeding schedule

  • Not being home for days at a time


Introduction
INTRODUCTION

  • My cats always wanted to eat at 5:30 am every morning. Not needing to get up until 6:15 it became a pain, because they are relentless when they want me to get up.

  • New work schedule keeps me away from home quite a bit. I need a solution to allow me to keep them on a regular feeding schedule without over feeding.

  • Tried store bought feeders that allow for food to refill itself.


Introduction cont
INTRODUCTION Cont.

  • Feeder that refills doesn’t work due to one of my cats abusing the endless food.

  • Got the idea for my feeder from Mathew Newton who came in second in Mac|Lifes: Top Ten Wonders of the Home Automation World. http://www.maclife-digital.com/maclife/201003/?pg=33#pg33


Problem statement
PROBLEM STATEMENT

  • Need a feeder automatically operate at two specific times in the day

  • Ability to control the feeder from locations away from home


Assumptions
Assumptions

  • That my cats will let me sleep as long as they have food at the right time.

  • That I will be able to stay away from home when needed without worry


Proposed solution
PROPOSED SOLUTION

  • Steps taken to solve the problem of the cats feeding time:

    • Deciding to use microcontroller or PLC

    • Went with the PLC after doing internet searches and found the Nano-10 PLC

    • Nano-10 offers what I needed regarding onboard server for web apps and Ethernet connections for network communication




Proposed solution cont2
PROPOSED SOLUTION Cont.

  • Assembly had a few difficult parts, filing the rod and coupling to connect the dispenser and the motor



Results
RESULTS

  • Functioning pet feeder

  • Automatically feeds twice a day

  • Ability to control feeder manually from inside or outside of home network


Conclusions
CONCLUSIONS

  • The results are very significant for my personal use, I have already been actively using the feeder

  • I have learned a lot regarding the PLC that I purchased as far as programming and capabilities.


Future work
FUTURE WORK

  • Redesign the exit ramp

  • Addition of water refill

  • Make it less bulky, take up less space

  • Addition of a network video camera to be able to monitor

  • Food level indicator
