There's a bunch of info on the net about this stuff. I think you can use just a relay to do this...

I'm missing the point of using the kitchen timer. You can do everything you want with just the PIC...
The point of the timer is an LCD screen and push buttons for $2 at local discount store.

I have already created one that is solely pic based, sets the camera off on intervals based on a potentiometer, from 1 to 255 seconds. I was next going to install and LCD screen with push buttons to do it all digitally, and found that the kitchen timer is cheaper than buying those parts individually.

The timer has button that when pushed at the end of the cycle, restarts the timer. Essentially, the button is connecting a pin on the CMOS to the VDD of the circuit. I may be able to use another transistor and have the timer reset itself without even using a pic...
