User / TomBenedict / Contact Mic in a Tin
Tom Benedict / 2,003 items
The tin has a non-conductive coating on it. This means you can glue the piezo disc straight into the bottom without risking a short, but it means you have to scrape or sand the coating off in order to attach the cable shield to the inside of the tin. The other two wires just solder straight to the piezo disc.
