Feeding cat remotely using smartphone

sa112

Do you wanna feed your pets from outdoor? I have made a feeding machine which can be controlled on the browser using smartphone.

 

 

What you need to prepare

  • Obniz
  • Battery or USB adaptor & cable
  • Screw and pipe
  • Servo motor ( unlimited rotation)
  • Pet food - as much as possible

 

Step 1

Cut pipes and prepare the screw. I made a screw by using 3D printer. Then, connect screw to a motor. and  put them into a box.

 

Step 2

Connect servo motor to obniz.

io0: GND,

io1: VCC,

io2: signal

 

Then power up your obniz.

Step 3

Write codes below and put food into the bottle. Food will come out from the pipe.

  • Very nice project.  Now, if I could only adapt this design to give my cat a pill.  I have an aging cat that requires about 2 1/2 pills a day, that he does not really want to take (for a while I was able to hide the pills in peanut butter, but he has since decided that peanut butter is no longer a snack).  The current method is to first find then cat, then usually extracting the cat from underneath a bed, then to prying his mouth open and shooting in the pill(s).  That would take one complex machine.

    >for a while I was able to hide the pills in peanut butter

     

    We were able to hide little pills in shrimp for Charlie Kat for a while. (antibiotics, thankfully temporary)

    And then for some reason those little pills were no longer available the next time we needed them. grrrr.

    Course, that would not work for Liney-Kat because he doesn't like shrimp.

     

    For a previous aging kitty, we had the meds mixed into custom treats for a while, which worked pretty well too.

    We have tried many 'pill pockets' and other treats to make the pill taking easier on poor 'Spike', but he has so few vices or favorites that we can use.  He did however take to his new food (special kidney diet) nicely, which was a good thing (for all of us).  I might have to experiment to see if I could find a 'custom treat' to his liking.

    Always such a trick to find the right way, isn't it?

     

    The pill pockets never worked for us either - I think generally they were just too big or would fall apart, plus the cats never liked them.

    The custom treats were specially prepared by a pharmacy and sealed into blister packs. They were even able to make it her favourite fish flavours. That only worked until the blister-pack machine kept improperly sealing the package and she wouldn't eat them anymore.

     

    Glad you're taking the effort to keep your aging kitty healthy image
