Dear Diary, I've known for some time what my project is going to be. It's based on a practical we did last year, about half way through the AS course. It was magic. By the end of the lesson, we all had small electric motors, which could be turned on by just touching two wires with a finger. It was such fun that we all took photos of the circuit with our mobiles and sent them off to our mates in the Common Room. The idea of using a tiny current in my skin to control a much larger current appeals.
