Fish Feeder 

An open-source automatic feeder for animal experiments. It is based on a movable reward disk controlled by a step motor that automatically delivers the pellets at the required time.

It can be interface through Bonsai or using external TTL commands.

Open-Source hardware design files, firmware, and design and assembly instructions for laser cut acrylic and 3D printed parts for the pellet dispensers are available from the public repository here.
