W6 -PIEZOELECTRIC CONTACT MIC

Today we are making piezoelectric contact mic. We learn how to tint and solder the cable and combine two cables, positive(red) and the negative (black/gold). There is another white cable inside for audio, but today we don’t touch that.

After soldering black cable on both ends, combine them by attach them close to each other then put the “heat shrink” to seal them properly. Then combine the red, after soldering we don’t have to seal with heat shrink because there are no metal component, therefore the black cable tape will do.
