Automatic pet feeders are not cheap, especially if you want one that can be controlled remotely. Fortunately for DIY enthusiasts, they are a great project to complete at home and ideal for incorporating IoT features and electronic sensors.
With a wide choice of designs available, you can create a highly customized automatic pet feeder out of everything from recycled Pringles cans to sleek 3D printed designs, or you can just enjoy games at best payout casino. Our list of the best homemade automatic pet feeders includes options for cats, dogs, rabbits, and even fish.
- DIY Pringles Can Cat Feeder
The first item on our list is a DIY cat feeder that costs about $15. The interesting part of this build is that you can recycle a Pringles can to serve as the main food chamber.
Instead of relying on a timer, this cat feeder releases food when your cat touches a button. The system’s mechanics are basic, with two cans held together by an electronic servo. Both cans have holes in them, allowing food to be discharged when they are lined up. Aside from the servo, you’ll need a push button to complete the circuit and an Arduino to control the entire system.
Setting aside the fact that you must initially teach your cat to press a button, this cat feeder could not be simpler or less expensive to set up.
- Pringles Can Smart Pet Feeder
This project expands on the Pringles can feeder by implementing automated feeding. Again, the mechanics include utilizing a servo to twist two cans together, which, when lined up, deliver food to your hungry cat.
Instead of an Arduino, you can utilize modular electronic components known as littleBits, which are available from Sphero and hotelgrouper. Add a useful little app called IFTTT (If This Then That) and you can quickly program your DIY Pringles feeder to release food exactly when you want using your smartphone.
- 3D Printed IoT Holiday Feeder
Do you need to leave for a day or two but cannot find someone to look after your cat? Then this sophisticated, 3D printed cat feeder is exactly what you need. This project’s concept is similar to older – fashioned cat feeders, however instead of using a mechanical timer, you control it with your phone.
For this project, you’ll need the Adafruit Feather HUZZAH with ESP8266 wireless connection and a continuous rotation micro servo. You will also need a 3D printer to create the food chamber. The 3D printing files may be downloaded from the project page on Fabble, which also includes thorough instructions on how to put everything together.
- Automatic IoT Enabled Rabbit Feeder
The benefit of designing your own circuit is that you can tailor the functionality to your own requirements. In this project, for example, the author included temperature and humidity sensors to ensure that their rabbits did not overheat in their cage.
While this project was designed for bunnies, you can use the same template for a cat or dog feeder.
To communicate wirelessly with the pet feeder, you’ll need an ESP-12F or a comparable board. Aside from that, you’ll need a DC motor, a rotation converter, and an RTC Time + EEPROM Module—which retains exact time and operates the feeder even when it can’t connect to the internet.
