• Derived from this project: T. Chordstrum PCB

  As this project refused to stop occupying my brain, more stuff just kept coming. Now there is a PCB and diy kit for building what I've called the T. Chordstrum. It uses either the tlc strummer firmware on a Teensy LC, or the Teensy 3.2 version of it all, with the addition of built in audio output. I even put a rhythm section in there, with samples from the Keio (Korg) Minipops 7. And it keeps on developing...

• Built in audio output

  This was not a thing on top of my list, but I got curious of the Karplus-Strong implementation in the Teensy Audio Library, and took 30 minutes of my lunch break to put it in my strummer. The Teensy Audio Library requires at least a Teensy 3.2 to work, but I had found a Teensy 3.2 lying around that I had almost forgotten. It even had an audio output jack set up already. With some help from Paul Stoffregen's Touch Guitar code, I had the Teensy 3.2 programmed and working in no time, and the result was not bad at all. Very autoharp sounding :)

  I have added the new code to the Github repo.

  And a litte video snippet for you...
