In the end I opted for the peanut butter radio in the following link Electronics has always been a bit of a mystery to me, I understand what the individual bits do but arranging them to do something useful other than lighting up a LED is beyond me. I had stumbled onto some websites showing circuit diagrams for VLF radios to listen for lightning - the astronomy bit is that they can also apparently pick up the effects auroras :). So I had been thinking about a little project for my holiday. I need to get round to building a case for my ST102, but with a lot of diy recently I can't quite face any more sawing.
