The following videos are displaying patterns generated by a Processing program doing real-time FFT (Fast Fourier transform). Basically it is visualizing music in the frequency domain using a polar-coordinate particle system.
The hardware makes use of Adafruit 8×8 neopixles, two 5v 10amp supplies, a FadeCandy controller, 16 AWG stranded wire , 20 AWG stranded wire, (2 – Female 2.1×5.5mm DC Power Cable Jack Adapter), and some plastic stand offs.
