I am currently trying to buy a prefabbed board which wil do this... BUT the production on the boards is limited and the next batch won't be out for several months. I need it to add the finishing touches on my Stormtrooper Armor Suit. The unit basically amplifies the audio and then when you get done talking it plays a short static burst.. like white noise or squelch on a radio... Would be nice to build a home brew of this. Anyone have any ideas they would be willing to share?
Cheers,

Is there a push-to-talk button anywhere that you could hack into to trigger a PIC into making the sound for you? The 'push' would arm the PIC to make the sound, and after the 'push' has been held for X seconds, it would actually be armed, then the 'release' would trigger the PIC to make white noise for X ms.
