Technology enthusiast and cat fancier 'joe' has described a project to amuse the cat without too much interaction on his part. By mounting a laser pointer on a servo-controlled tilt/pan unit, his Arduino board can point the laser beam in various directions to amuse the cat. This project also has other applications - just add a more powerful laser beam and your imagination. In the meanwhile, here's a demonstration of the toy in action:
The instructions and Arduino code can be found here. To get started with your own Cat Laser or replica laser weapons, consider our Freetronics Eleven - the Arduino-Uno compatible with low-profile USB socket, onboard prototyping space and easy to view LEDs:
