In other experiments with sound I have learnt to make a 'contact microphone' with components from maplins, and following instructions on sound artist John Grzinich's website (thanks John!). As the name implies a contact microphone records sound by being in contact with the vibrations of the surface of an object. I began doing this so that I could record the sound of a kite while it was flying, although this is still yet to happen!

This avenue of research is beginning to change too. I think the contact microphone might be more useful in amplifying the sounds that objects make when the tapping machine taps the rhythm of movement.
