How to Make a Contact Mic (Piezo Pick-up) for under $10

  • 1/4″ audio cable (eg radioshack 42-2381A)
  • tape, solder, hot glue, heat shrink tubing, etc

That’s all! It’s pretty simple an inexpensive: two piezos and a six foot cable cost me ten dollars and yield two mics. You also probably going to use pliers, a razor blade, and a soldering iron or hot glue gun if you have them.
