Hi everyone,
I'd like to build this device using a teensy and an audio shield, essentially re-creating the circuit as a digital one.

There's some very well documented details on Luigi's page. My initial idea was to simply hook up the piezo/contact mic directly to the mic input of the audio shield, and then take one of the line-out pins and hook it up to an LM386 in order to amplify the signal.
Does this make sense? Or is there more going on in the circuit that I'm missing? Luigi's circuit runs on 9V, so therefore I figured it's best to only take the part which amplifies the signal.
Any suggestions around this would be really appreciated. I've worked plenty with microcontrollers and 5/3.3V logic, but 9V analog circuits are a bit new to me.
Best,
Mickey
