> The product requires a compatible iOS device to operate (iPhone 5, 5C,5S, 6, 6+). Well that sucks! Why would they lock themselves to a platform like that?

Most likely due to lack of resources.

Why does it need a mobile phone to work at all?!

this is a great project! i'm working on a go rewrite right now (i wish the author had chosen a less broken language in the first place lol). question: how hard would it be to make this work for a nutrient suspension? i'm asking because i have switched to soylent (for obvious reasons that i will not belabor here) but am frustrated that i still have to remember to prepare and consume it at the correct interval. it woul…

I mean this in the nicest way possible, but is this satire? I actually can't tell. Between go rewrite, criticizing the language choice, and wanting to just stick a tube in your mouth and be automatically fed soylent this almost seems generated by a markov chain. If sincere I apologize.

I'm mostly impressed that this kind of Poe's Law material is the only comment on a 1400 day old account.

Sorry to be boring but a simple timer seems more sensible. Dispense the preset amount everyday at the same time. And kitty needs water.

Water and food have different needs; an automatic water fountain like http://www.amazon.com/Drinkwell-Platinum-Pet-Fountain-168oz/... keeps a pool of water fresh at all times, without needing to dispense a particular measure of it.

Problem is: people in the node.js community have a pattern of going from the "weekend hack" to the "production" stage in weeks. Code maturity has no meaning to some.

I built one of these a couple of months ago using a rPI and a simple relay to control the 12v feed to one of these:

    http://www.super-feeder.com/csfmodel.html
Literally the code to feed them is a crontab:

    0 5,11,17 * * * /home/pi/bin/feed - > /dev/null 2>&1
Using this script in /home/pi/bin/feed:

    #!/bin/bash

    export PATH=$HOME/bin:$PATH

    (
        source gpio
        echo "Using pin 12"
        gpio mode 12 out
        gpio mode 12 out
        gpio write 12 0
        sleep 1
        echo "Turn On"
        gpio write 12 1
        sleep 20
        echo "Turn Off"
        gpio write 12 0
    ) 2>&1 | logger -p local0.info -s -t feed

    gpio write 12 0

    exit 0

    /home/pi/bin/gpio is from here: https://github.com/lasandell/RaspberryPi.git
I re-wrote it this weekend as a Openresty powered API (nginx+luajit) and put a web page on with a feed from the picam so my wife could look at the bowl and hit a button to dispense more if the cats needed it.

Your comment made me laugh really loud in an office that is dead quiet right now. Just thought you should know.

"it would be truly liberating to simply insert a tube into my mouth that would dispense an appropriate amount of fuel"

It's Happening!

It probably doesn't -- there's likely an API that the app calls, and that one could, with time, mimic it. That would also require the intersection of people with the tools, cats, and inclination.

I'm looking to build something similar. What did you use as a hopper?

What do you mean? What do you feed them instead? Curious. I have 3 cats and they are on the kibble. 1 of them has IBS. I always wonder(ed) if it's cos of this solid food full or "fillers".

Wet food is almost certainly healthier for cats. Less carbs, more moisture, fewer urinary tract issues, etc. Kibble is great for when you need to get away for the weekend, however.

How do your cats maintain clean teeth when on solely wet food? I had thought the kibble helped with that, but that may have been more because of my prior cat's allergies than the food itself.
