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
Via the forum.
Check out the video after the break.
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.
“The project is obviously open hardware/source”
…except for his algorithms he used to actually detect the whistling :(
