Jonathan completed a beautiful project: a sound sculpture. Jonathan describes it as the culmination of a decade of learning, and in a moment you’ll understand why.
The sculpture itself is a beautiful display of woodwork mixed with what appear to be individually addressable LED’s. The varying length of the individual enclosures evokes the idea that the sculpture is somehow involved in the sound production, which is a nice touch.
An Adafruit microphone module feeds detected audio into a PSoC 5 microcontroller. You’d expect that Jonathan just used one of the FFT libraries that are available. But you’ll recall that this was the culmination of a decade of learning- why so? Because Jonathan went through the process of procuring his own grey hairs by writing his own FFT function. A homebrew FFT function and blinkenlites? What’s not to love!
