Got tired of having to copy MP3s over to the PI for a lightshow. So I wrote a new bit of software for the PC. Python code on PC that uses ‘Stereo Mix’ and does the FFT on anything that’s playing. The calculated values are then streamed UDP onto the local network where any machine can grab them. The PI captures the data, applies any pwm/onoff rules for the pins and then blinks the lights.
yea! blinky lights!
Since it is using Stereo Mix on the PC, it blinks lights for everything: Pandora, Youtube, Netflix, MKV, MP3, MP4, what-have-you
the PC is a Celeron and Pythonw was running about 40% CPU. The “Bass Stacks” are spools of lights from HD that were on sale after xmas. Each is something like 300 lights. All lights on is just over 3 amps, just the “Bass Stacks” use 2.4A
Read more. And see an experiment with streaming FFT over UDP for the project below.
