Aquarium Fish Feeder
Automating aquarium feeding with 3D-printed mechanics.
Context
The project
This automatic feeder combines 3D-printed parts, a Raspberry Pi, a servo motor, and a small web service. The repository documents printing, assembly, configuration, and IFTTT automation.
Objectives
Design challenges
- 01
Build a compact, reproducible mechanism from published 3D files.
- 02
Control the servo’s feeding and reload positions precisely.
- 03
Trigger the action remotely and retain a feeding log.
