    Hi all. It turned out to not just be code... I wasn't seating my Teensy deeply enough into the breadboard. For any other n00bs out there--make sure that the pins of your Teensy almost completely...

    I eventually figured this out. The main issue I was having is that I was using way too high of a resistance value for my parallel resistors. Reducing it to more like 40kOhm (from 2MOhm) helped with...

    How to reduce piezo bounce for analog input

    Hi all,

    I'm making an electric drumset using basic piezos and a teensy 3.2. I've got it working well enough for slow playing, as long as I adjust some variables to ignore piezo activity in...

    Rather embarrassingly, I just realized that the code I was using to debug the situation, was not setting a variable after a hit was registered, which was creating the illusion of a linkage/weird...

    Hi Paul! That's not a silly question at all! I did think of the vibration hitting multiple discs though. My current setup is each of my two piezos is taped to a laser disc, and soldered to some...

    It looks like it's going to be a bit of a task for me to get an oscilloscope, is there anything I can try without one? I do have a cheap multimeter if that helps

    Do I need to get zeners with a...

    I'm just tapping the laser discs I have them taped to with my hand or a drum stick, but they're soldered to some long wires that go to a breadboard and I have them pretty spread out, so I don't think...

    Thanks for the quick response! I ran out and got a few zeners, and replaced the switching diodes, but it didn't seem to change anything :/ It seems like I must be missing something to keep the...
  9. multiple drum-trigger piezos seem to be interfering with each other

    Hi all,

    I'm attempting to make a drumset with piezos and a teensy 3.2, using the piezo-wiring diagram that kpc posted here: ...
