If you don’t have enough things staring at you and shaking their head in frustration, [Sheerforce] has a neat project for you. It’s a small Arduino-powered robot that uses an ultrasonic distance finder to keep pointing towards the closest thing it can find. Generally, that would be you.
When it finds something, it tries to track it by constantly rotating the distance finder slightly and retesting the distance, giving the impression of constantly shaking its head at you in disappointment. This ensures that you will either unplug it or smash it with a hammer after a very short time, but you should read [Sheerforce]’s code first: it’s a great example of documenting this for experimenters who want to build something that offers more affirmations of your life choices.
