Final Project¶
Planning the final project¶
Final Project concept :¶
Being a mom to an awesome middle-aged cat who needs constant attention about his health , I’ve always needed a device to assest in that . but all I can find was a pet feeder . I want to make something that can provide more : mentoring food and water , bathroom visits , maybe entertaining as well .
Product thinking :¶
This project should be useful to anyone having trouble tracking his pet’s behaviour . It should enable the user to control & monitor how much his pet eats , drinks & visits toilet . I’m thinking about a food despencer , maybe some mechanism & a sensor to track how much is eaten . I’m considering motion sensors to detect drinking and toilet visits . Maybe a screen to show data as well as transfering it to a phone . Still working on how this whole thing could be functional in the case of having 2 cats .
Initial Sketches :¶
Core Module¶
Construction Parts¶
The tower : cut as “Make something Big” assingment , MDF .
Input Devices¶
Motion Detector : To count the number of toilet visits . Weight Measuring : To keep track how much the cat eats . Push Button : To manually despence food (Thinking about training the cat to push it itself)
Output Devices¶
LCD : To show some statics collected . Motor : Despence food .
Microcontroller¶
Propably Attiny44
Power Managment¶
Power supply for motor
Interfacing & Communication¶
Still searching for a suitable way to send collected data to phone so it could be monitered remotely
Cat Tree structure¶
Thinking of a cat tower to implement my final project , as it will provide even more for my cats .
Fusion¶
Did a quick sketch inspired by some cat towers , thinking about adding briges later
Makit¶
Had fun creating a makit of a 1:3 scale ,
So we have a Cat Tower which :
-
Despences food
-
Weighs it to keep track how much the cat eats.
-
Has a toilet room with a motion detection sensor to count how many times the cat visits the toilet .
-
Has a Screen to show the collected statics .
-
A button for despencing food .
Food Dispencer¶
Design¶
Worked on fusion , designing each part
The Tank
The Tank’s Lid
The food Door
Door Open
Door closed
Remains the motor mount ..

Fabrication¶
Cat Tower¶
Using the Makit to visualize ,, I drew each room on Fusion , And cut them on Simplex router .
All details are in Week 7 assingment
Then I added thread around the pipes as cats’ scratching poles .
Feeder¶
Using the circuit made on Week 12 assignment
And learning about ” 4 Bar rocker mechanism ” ,
I made my food dispencer and installed it in the Cat tower .
Started with some Prusa Music
Printing in progress
Done
cut the bars on Laser cutter
Tested their movement
Made a Holder for the board
and a base for the motor
And installed all in the Feeder Room
Sensor¶
Using the circuit made on Week 10 asignment
Made a mount for the Sensor and and the board .
I added a led and installed in a room to monitor cat’s visit in it .
Later on , I plan to upgrade the system where this sensor can send readings to a mobile app or something .
