“The Boldport Cordwood has 6 LEDs. My guitar has 6 strings. So let’s make a tuner..
The Boldport Cordwood has six LEDs. Six is one of my favourite numbers .. like the number of strings on a standard guitar.
So is it possible to use the Cordwood to detect (even tune) the six strings of a guitar?
I was thinking about doing a complete analog solution with bandpass filters (probably active filters in order to get very tight passband frequencies). Maybe later, but to start I wanted to try an Arduino-based approach with an electret pre-amp straight into the AVR with a little signal processing in software.”
