#catfeeder

  • Aaron Parecki
    I made more progress on the cat feeder tonight! ⁣
    ⁣I attached the motor to the back, and the shaft now goes thru and connects to the original (modified) plastic shaft from the dispenser.
    ⁣
    ⁣The lid has an ultrasonic distance sensor pointing down at the food to be able to tell how much is left in the chute.
    ⁣
    ⁣There's a button on top to be able to manually dispense a dose.
    ⁣
    ⁣Lastly, I added a terminal block to connect the wires from the scale for easier mounting to the processor later.
    ⁣
    ⁣Next up, I need to start connecting all the components to the circuitry! The load cell amplifier, stepper motor driver, and finally the esp32 controller. Then it'll be time to write some software!

    I fell into a deep deep Internet hole today and ended up designing and buying parts for a raspberry-pi cat feeder built in to an Ikea shelf that doubles as a scratching post and bed, cat-climbing wall art, as well as a drink-mixing robot built in to an Ikea coffee table. Amazingly, all the parts are coming from Ikea, Amazon and Sparkfun. I've got some fun projects ahead of me! :-)

Hi, I'm Aaron Parecki, Director of Identity Standards at Okta, and co-founder of IndieWebCamp. I maintain oauth.net, write and consult about OAuth, and participate in the OAuth Working Group at the IETF. I also help people learn about video production and livestreaming. (detailed bio)

I've been tracking my location since 2008 and I wrote 100 songs in 100 days. I've spoken at conferences around the world about owning your data, OAuth, quantified self, and explained why R is a vowel. Read more.
