Raspberry pi 3 cat feeder free

As with many of my projects, it started with something that made me angry. Back to about 8 or so years ago. We had a cat at the time, Pumpkin, who as objectively not a good cat. She was foul tempered on the best of days and very difficult to love. She had a habit of wanting food precisely on time. And if it was late, she would raise all manner of noise until she was fed.

Often this came at some ungodly early time in the morning. First of all, it is very nearly impossible to program this thing. It may have the worst UX of any consumer product I have ever encountered. The controls on it do not make sense and are not labeled in any such way as to indicate how to program it. Thankfully, some kind soul put the instructions on their blog because I raspberry pi 3 cat feeder free have been lost without it.

And even worse, every time you change the batteries, it loses the program. It has no wiring for mains electrical or even an adapter, just D-cell batteries. And those batteries last just long enough for you to forget how you programmed it.

Second, it loses time. On the order of minutes a week. So a 7am feeding becomes a 5am feeding within a few months. Every few weeks you have to reset the clock back to the current time. My default setting was just to not touch it until I absolutely had to. Third, and perhaps most importantly, sometimes it legitimately just would not work. I even tried only filling it up halfway or a quarter of the frew to see if maybe there was just too much weight on the motor.

I tried taking it apart and cleaning raspberry pi 3 cat feeder free out thinking maybe a kibble got jammed somewhere. But nope. Raspbergy is literally one of the raspberry pi 3 cat feeder free нажмите сюда products I have ever owned. For the longest time, we just grumbled at how much it raspberry pi 3 cat feeder free and dealt with it.

When we had to put Pumpkin down, I happily put it in the attic raspberry pi 3 cat feeder free was content to hopefully never have to think about it again. So when we got two new cats last year, I at first resisted getting the Petmate back out. We just kinda made due by pouring food out in the mornings and evenings. But then we noticed our cats were gaining weight. Too much weight, in fact, because they were overeating. We really needed feedet ability to feed them on a raspberry pi 3 cat feeder free, a controlled portion to keep them at a healthy weight.

So I grumbled, and got the Petmate back out of the attic. And, imagine that, it still razpberry just as much as it ever did. So I started thinking.

Before this project, almost the entirety of my professional experience has been in software. So this seemed like a good chance to learn. But I quickly concluded this was raspberry pi 3 cat feeder free not a good idea based as many of the components inside were custom.

So, like any good engineer, I decided to build my own. It had to be easily programmable, preferably from a phone or laptop. Easily programmable to the point where my wife could do it if she had to. After search around for awhile pet feeders are a feeeder common first hardware project, so there are lots out there to choose fromI decided to base my design raspbeerry this onebut with some modifications and raspberry pi 3 cat feeder free completely different software program.

I also modified the design pretty heavily because, well, I want it to look nice in my house. I have open sourced the software I wrote for this project under the name petfeedd. It is available on Github.

It implements a multi-threaded daemon I said this was overengineered 😛 that operates all facets of the feeder. An auto-discovery protocol that can fedder used to find feeders on your network. Useful for writing third party clients. Start by taking apart the food dispenser. Take the knob off and recycle it too. Raspberry pi 3 cat feeder free the spinner raspberfy of the dispenser and look at it. Notice the little notch in the spinner?

I just used a pocket knife for this. Next, take your small thin piece of wood. I used a hole bore for this but you could just as easily just cut a square piece off of it. Whatever it is, it should be square or round, with a hole as close to the center as you can possibly make it.

This hole should snugly fit the dowel you just made. You raspbsrry should end up with something that looks like this:. First, take note of how the dispenser body is shaped. Take the PVC piece. You should end up with something like this. Now, on a scrap piece of wood, squirt a small amount of epoxy, about the size of a half dollar, onto the wood and mix together using a spatula.

Best to do this outside fefder this stuff smells awful. Using the spatula, gently apply a quarter-inch bead of epoxy around the outside bottom of the dispenser body. Press the PVC onto привожу ссылку feeder, with the carriage bolt facing backwards and in line with the notch gree raspberry pi 3 cat feeder free hole for the spinner, and tape it into place.

Allow it to cure for at least an hour. These will be the pieces that connect the dispenser body to the base. Then cut this into two smaller pieces. This will hold the servo in place. So on your plaque, mark the centerline, then the bottom and top locations. The servo pieces will go 1. Apply a small amount of wood glue and press the dowel pieces onto the board. Now, take your servo and center it on the line one узнать больше above the bottom dowel pj just glued, and press the two small wood pieces you have on either side.

Mark their locations using a pencil, raspberry pi 3 cat feeder free the servo out, apply wood glue and glue the pieces in. Your end product should look like this:. Allow it to set overnight. If you are going to paint, now is the time to do it. This is what mine looked like after two coats of paint. Flip the plaque over and, using a slightly larger drill bit, drill out just enough on the back of each hole to hold the bolt.

Additionally, drill two small holes through the plaque at the top and bottom. These are how you will mount it on the wall. Carefully drill a hole through the plastic dispenser body at the location you just marked. Do not apply too much pressure or you will crack or break the dispenser. Now, test putting everything together. Take the rotator arm you built raspberry pi 3 cat feeder free step 1. Your servo should have come with some plastic attachments.

I used the X-shaped one. Using the included screws, attach it to the back of the rotator arm. You need to try to get it as close to the center as you possibly can. Install Raspbian on your Raspberry Ссылка на подробности. Follow the instructions for installing the raspberry pi 3 cat feeder free source code I адрес for this project available on Github petfeedd.

Assemble the entire feeder, including the servo. Put it in this spot and screw it down. Mount the Raspberry Pi inside the case and put the middle part but not the top part on. Your servo has 3 wires: white, black and red.

Red is power, black is ground, and white is control. If not, double check your wiring. Then, push as much of the extra wiring as you can into the top of the case and put the top cover on, hiding the additional wiring.

Unscrew the top carriage bolt, lift up and remove the servo temporarily but allow it to be connected. Then, spin the feeder to the side allowing you to access the mounting holes ip drilled.

The python script is simple. The way I feecer it is just to have to motor seek its minimum point, but there isn’t one because the servo is continuous rotation, it will just keep spinning counter clockwise raspberry pi 3 cat feeder free the script ends. I have my servo signal connected на этой странице GPIO The script: Servo.

The results of this study showed that the design of the dispenser will have a beneficial social impact. Concept One of my requirements was that the food had to be fully enclosed, so the kibble would not be exposed to the air to give off tempting aromas and would be inaccessible to prying paws. ReneaC Question 3 years ago. Allow raspnerry to cure for at least an hour.
