Introduction: Automatic Dog Feeder

Automatic Dog Feeder

Automatic Dog Feeder

I was going out of town for a few days, I had no one to watch my dog
so I built an automatic dog food dispenser. Trouble is I used 1-1/2” PVC pipe
for the outlet, so you had to shake the bucket to dispense the food. Luckily I
found someone to check on her every day after work. Anyways it wasn't to
This is my second version and it works quite well.

This is my first Instructable, so mistakes are possible (or not I hope)

Materials needed:
1 – Plastic 5 gal. Bucket (can be obtained at most fast food places for free or some will
charge a buck or two.)

1 – 12” piece of PVC pipe (length depends on the height you mount your feeder at,
bottom of pipe has to reach the bottom of the dog bowl.)

4 – ½/x/2” x1/8 thk aluminum strips or 4 pieces 1”aluminum angle 1/2” wide.

1 – 3/8 piece of plywood large enough to cut a circle out of to fit in the bottom of the

4 – 10-24 screws ¾” long

4 – 10-24 screws 1-1/2” long

8 – 10-24 nuts

Step 1:

Cut the PVC pipe in half to a depth you want the dog food to be, then cut that section off.
Step 2:

Cut the plywood disk to fit the bottom of the bucket. Now cut a hole about 3/4” from the edge the size of the 3” pipe.

Step 3:

Cut a hole in the bottom of the bucket to match

Step 4:

Bend the strips of aluminum so that they are 1” angles or just use pieces of aluminum
angle in the first place. I didn't have any angle so I had to use strips
Put them across from each other on the inside of the upper lip of the pipe with the
tabs pointing out, and drill through the pipe and angle for the 3/4” Long 10-24 screws.
Bolt together.

Put pipe through the hole in the plywood and drill through the tabs and the plywood for the longer screws.

Step 5:

Take apart, place disk upside down on bottom of bucket and drill though holes, I had to grind away part of the bottom edge of the bucket case there was a rim where the screw went through. (no pic for step 5, I forgot to take one.)

Step 6:

Automatic Dog Feeder

Put plywood disk back in bucket, insert pipe and bolt all together. I filled in the gaps I had with hot melt glue.

Step 7: Take out and set up and fill with dog food.

Thanks. Although we don't have a dog at present, I like this so much that I am going to keep it "for future dog(s)." Since there is a constant plague of small ants where we live, I would also have to make sure none can enter the bucket from the top, and also run a stripe of vaseline around the pipe that sends the kibble to the dish, perhaps near where it exits the bucket, and have another stripe of vaseline around the bottom of the dog's dish. They won't cross the stripes unless the vaseline gets so dirty with other things that the ants find a "bridge."

This is a great Instructable, but you need to add a main image for the project, even if it's just a video that you're trying to publish. The image needs to be uploaded to the editor so that it shows up. Otherwise it looks like your project has no main image. You only need to do this with one image.

Please do that, and leave me a message when you have so that we can publish your work.
