One of my cat can eat until he dies (see illustration bellow). I had to prevent this.
I will share the plans once they're done. Ofc it's a wip project, then it could change over time.
- Stepper:
Nema 17
- Stepper controller:
A4988
- Card:
ESP-12E
(but should work with anyESP8266
) - Power supply: an old computer PSU. You probably have one or two in your garage, right next to your 512MB RAM parts.
