Domotica for self-study (Score 1)

Study yourself, your spouse and/or children. Seriously. Get some domotica installed, and monitor your activities as you lead your life. Formulate hypotheses and vary the circumstances. Besides the challenges involved in getting good readings, you will learn stuff about your family and yourselve that will otherwise always go unnoticed. And if you apply scientific rigor and creativity you might even get some real scientific results.
