Wilkinsburg After School: Microphone Building
Students at Wilkinsburg after school program learned about the inside parts of a microphone and how it all works together. Building the microphones out of household materials using just two magnets, a length of copper wire, three washers, a nut, a bolt, plastic straw and cup. Then, after sanding off an insulating coating on their makeshift leads, they were able to test their finished DIY mics by connecting them to a mixer and speakers using alligator clips.
