videoman at Twin Cities maker has built a Cat Feeder which is controlled by a Raspberry Pi, here is a quote from the source:
Ya know, so the cats don’t over eat, and maybe have a mixture of food, and it’s super cool! (Did I mention that it’s cool!?) So… five days before leaving town, I purchased the food hopper, and very quickly ran out of time to complete the project before leaving on vacation. So plan B it was, a large bowl of cat food , and water.
However, I did stick with my original plan, and saw the build to completion well before my next trip out of town. In this blog post, I’ll list out the step-by-step (for the most part) process to building your very own Wifi Enabled Raspberry Pi Powered Cat/Human Feeder.
I’ve published a Google spreadsheet here, that lists the specific parts and components that you need to acquire for this project. It’s really simple, and can be easily assymbled in about 4-6 hours once you have all the parts.
- Soldering Iron
- 1/2″ drill bit
- 1″ drill bit (for push button switch, optional)
- Hot glue gun + glue
- Wire cutter
Prerequisites for the build:
- Have all the parts on-hand, check out the Google spread sheet.
- Have a working and installed an OS on the Pi. Adafruit Occidentalis or Raspbianwork well.
- Have the Wifi Adaptor setup and ready to go: Occidentalis or Raspbian
- Play around with the GPIO in and out on the Pi by downloading the code from myGitHub Repo
- Install the Python GPIO.PWM module: RPIO install docs
