My housemate's cat, Roxanne, is always playful and I needed a way to keep her entertained while working. There was only one way.
Cats love lasers.
Introducing the Laser Tower 3000. It's an Arduino project that I worked on which helps point a laser at random directions using servo motors powered by a battery pack, all held together by 3D printed parts.
Wiring Diagram
Two servo motors are connected to the Arduino, which serve as the pitch and yaw axes. The Arduino is then connected to a battery pack for power.

Assembly
The servo motors and laser pointer are attached to a 3D printed modified model plane camera gimbal. All the electronic components are placed on a 3D printed platform that is secured to the battery pack for portability.

Code
The code is was written to randomize the pitch and yaw axes, with limits to keep the laser direction within range.

Final Results
The end product is a portable laser tower and a very happy cat!
