SnackClock

A super-simple device for dispensing pre-measured food (for pets or research) at regular intervals throughout the day

Similar projects worth following
SnackClock dispenses food at regular intervals throughout the day. It was designed for use with mice in a research setting, but can be used for pets or other applications requiring a regular dispense of a pre-measured quantify of food.

This is a VERY simple feeding device.  SnackClock utilizes a 24-hour clock movement and two 3D printed pieces to dispense food at regular intervals. Basically the clock goes around and pushes food out.  There is no coding or micro-controller required and the clock movement should run for >1 year on a single AA battery.  

The 3D parts can be adapted to fit different types of caging. 

Snackclock could be to use a stepper motor for less regular or irregular dispensing times.  For instance, a "weekly" clock movement could be a good "vacation" fish feeder.  Check out this blog post by Mahto about how to mess with the timing of a clock movement.  Please post comments on how this works out if you try this!
