Also want to look into simple to make touch sensitive switches: http://www.bytecraft.com/Touch_Sensitive_Switch

char touch_switch (void)   {
  pb_direction = output;
  pb.0 = 0;    // Discharge the pin     
  delay_Ms(1);          // Wait
  pb_direction = input; // Turn on the Constant current source     
  delay_Us(5);          // Wait for 5 u_seconds     
  if (pb.0 == 1) return (0);         // No touch detected     
  else return (1);         // Touch detected   
}

Ok, I'm going back to the palmpilot stuff. Just had to get all that out before I left atmega land for a while.
