Excellent build from La Fabrique DIY up on Imgur!

This is a cat laser tower.
My cat and I live in a small appartement where there is not much to hunt for.
An Arduino moves the laser pseudo-randomly reproducing the behaviour of an insect and training the cat to become a ninja.
The brightness of the laser was boosted only for the purpose of the video. The final circuit includes some resistors to make it less dangerous for the eyes.
