Feed Them 2.0

by Jess_dpr

Published on May 1, 2016

Feed Them 2.0, is a remote pet feeder experiment for Ubiquitous Computing at University of Madeira. The prototype allows the owner to feed his pet even if he's not around. The prototype uses "littleBits" and IFTT to feed the animal, call for him using his owner's voice and to alert the owner if the main food storage is running low. It keeps the pet happier with the owner's voice and always has food when needed.

The materials used are wood for the main structure, motor support and opening flap. The main food container is just the cardboard tube from the inside of a kitchen paper roll (can be a pringles can or something similar).

For the sound and servo, there's a w20 cloud attached to a p3usb power, a w19 split that connects the cloud to a i25 mp3 player with a o24 synth speaker and the other end to a o11 servo with a motor connected to the opening flap.

Duration: 2 hours

How To Make It

STEP 1 : Wood Support

Cut a piece of wood board to create the base

STEP 2 : Vertical Wood Support

Cut a thin wood board and attached with nails or glue to the horizontal support in an inverted 'T' shape.

STEP 3 : Food Container

Glue the cardboard tube to the vertical support as high as you can. Dimensions depend on​ the animal you intend to feed (for dogs it should be bigger and smaller for cats). You should attach something to the bottom to create a little bottle neck almost at the end. This "step" almost defines the amount of food to be instantly dropped into the tray.

STEP 4 : Servo Support

Cut a small piece of wood and align with the base of the tube in order for the servo to be at the edge of the tube. The small wood board should be attached horizontally to the vertical​ support with an angle to the front.

STEP 5 : Container flap

Cut a round piece of thin wood with the same diameter as the container and attach it to the top of the servo (using servo accessories on top of the motor like the circular one), using double sided duct tape.

STEP 6 : Attaching the servo

Drill two holes (that can fit a zip tie) in the servo support with the same width as the servo. Position the servo with the attached flap tightly to the cardboard tube.

STEP 7 : Circuit

Mount the circuit onto​ a board and attach it to the back of the vertical support using a zip tie.

STEP 8 : Food Sensor

Create the food sensor onto a board and place it inside the container. Remember that the light and sensor need to be almost at the bottom of the container, creating a threshold for the food level. (The details of this circuit are yet to be implemented).

STEP 9 : Connecting

Connect both clouds using an usb cable and configure the wireless with the littlebits control panel of your account.
