The chart page also suggests on another line that the MPF102 can substitute for the NTE457, so I suspect this may be a matter of tolerances rather than suitability, in which case the NTE312 is a good replacement part for the preamp circuit - is this correct? I'm swimming in very deep waters with strong currents (unlike the piezo disk.) for me. I checked this cross-reference chart and it says that the NTE451 is the appropriate substitute, but they don't have that.

My at-hand and available options are:ġ - According to their website, my local electronics shop does not have MPF102s, but they have one NTE312 in stock.

As such, audio fidelity is not the primary concern, just amplifying the piezo's signal enough to give the lights something to react to.įirst off, can I just plug the piezo right into one of the Arduino's analog inputs and just go from there? I think the arduino needs a stronger signal?Īssuming the answer to the last question is that yes, I need to preamp the signal before I can process it in the arduino, then I have all the parts at hand for the simple preamp shown in this video except for the MPF102 JFET. I'm using a piezo disk in a cigar box guitar-type enclosure, but not as an audio amplifier - it is going to control a light organ.
