Lil Bang (Sound Trigger for Cameras)

Introduction
Now that I can take pictures of lightning I decided that I also want to be able to trigger my camera with sound. The design I came up with has the following features:

Controlled by a PIC micro (PIC16F886).
Adjustable sensitivity
Adjustable delay – i.e. the user can set how many milliseconds after the sound event the picture should be taken. (My uncle says it would be a lot better if there was a setting to define how much BEFORE the event it should trigger the camera – but that’s another project – for my Nobel prize later this year…J)
Operated from battery and/or external power brick.
Completely decoupled from the camera by opto couplers, so that no harm can be caused by the circuit to the camera.
Can be used with any camera that has a remote control input (direct, IR or otherwise).
Can also be used to trigger any other electronic device, e.g. flash
