Contact microphones for interactive project

Aug. 7, 2017

Two out of eight microphones for a project with interactive live electronics are now soldered and ready. The design for the piezo preamp I used is available here: or as a kit/per-built:

The two piezo elements sound slightly different and seem to amplify the sound to different degrees. The larger membrane dists (in the preamp?) even with the gain on the soundcard at 0 (the signal doesn't clip). I hope to be able to make some more thorough tests down the line.
