Collin’s Lab: DIY Contact Mic

Collin Cunningham — Tue, 20 Dec 2011 18:00:50 +0000

It's amazing what a little disk can do … when it's layered with piezoelectric crystals. Piezo disks are impressively sensitive to vibration and can easily be adapted to work as a contact microphones. The trick is the preamp - a basic circuit used to match the piezo's signal to levels compatible with modern audio gear inputs. The resulting piezo/preamp combo can be used for electrifying an acoustic guitar or simply exploring the lesser-heard world of small sound around us.

My spin of the Secret Santa wheel placed MAKE's art director, Jason Babler, squarely within my gift-giving crosshairs. Having never officially met Jason in corporeal meatspace, I was a bit stumped as to what material item he might enjoy owning. Thankfully, a little bird (named Gareth) clued me in on Mr. Babler's appreciation of fantasy-themed resin kits.
