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

Hey guys!

I thought it would be nice for once to share one project I just finished:

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

I made a very simple explaining video http://www.youtube.com/watch?feature=player_embedded&v=1eIxAMKNphwand also a one hour and a half video where I'm testing the whistled against false positives: http://www.youtube.com/watch?v=WFnKSA2ZDFY

You can find more details on my website:

hey guys!

Thanks for having posted this project on the main page :) .

For those interested in meddling with the platform, I implemented a simple word recognition on the platform.
Here is the link to my blog article containing a nice explanation video:
