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. Editable files are here:
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!
