Don’t forget that you can find all sorts of great rod and disk piezos in various sizes and configurations (and at great prices!) over at C. B. Gitty Crafter Supply.
First, a little bit of piezo basics. Piezoelectric elements, whatever the type, are based around layered ceramic wafers and conductive metal. Continue reading “Rod Piezo Primer”
