Piezo contact microphone construction

February 10, 2011

Today is the second of what I project to be three days of contact mic construction.

Students strip microphone cable, twist the copper, and solder it to piezo discs. We test them on our Sony handheld recorder.

While small groups construct mica, the rest of the class continues to research and blog about their mythical trees. They are looking for inspiration in myth, art, and poetry as they plan to sonify a real tree.

The microphone construction is slow. It is difficult to strip and twist such small wires. I have also inhaled way too much vaporized solder as students operate the iron for the first time. About 65% of all the students have finished contact mics.
