Turning on/off lights by whistling (Cortex M4 @ 80FFTs/sec)

Limpkin informs us that he recently finished work on his open source project:  Turning on/off lights by whistling

Basically, it is an ARM Cortex M4 running 80FFTs per second to detect a whistling sequence.  The project is obviously open hardware/source

    Definitely the right way, but not the only way. Has been done before, Check this out.

    He is doing his FFT based detection on a Linux PC coz he is using a Attiny to control the lights.

    Will try it out with my TI Staunchpad one of these days.

    …except for his algorithms he used to actually detect the whistling :(

    To prevent “bad quality copies that may appear later on dx-like websites.”
