Automatic PetFeeder

thingiverse

Created this several years ago but never got it fully working, but I figured the 3d models could be reused by someone else or used as a base for another project.This was original designed to use an ESP8266/ESP32 along with some other off the shelf parts from Adafruit (listed below). But the stl that houses all of the electronics was made to be replaced/updated, so that I could replace the ESP8266 with a Pi or any other configuration.You can also find the original firmware and Android app that I wrote for this here: https://github.com/marsara9/PetFeeder. The exploded view / assembly instructions are in the original Sketchup file on github, although this is meant to just snap together. Note though that I haven't touched the code on github in years and while the firmware works, the Android app is mostly incomplete.The main roadblock that I ran into wasn't able to find a way to get enough volts to the stepper motor in order to turn the "auger" with the weight of the food.BOM from Adafruit:ESP8266: https://www.adafruit.com/product/2471TB6612: https://www.adafruit.com/product/2448Battery: https://www.adafruit.com/product/353Powerboost 1000: https://www.adafruit.com/product/2465USB-C Breakout: https://www.adafruit.com/product/4090SD Card breakout: https://www.adafruit.com/product/254Breadboard: https://www.adafruit.com/product/589Stepper Motor: https://www.adafruit.com/product/324On/Off switch: https://www.adafruit.com/product/915
