   Electronic can be quite frustrating.   
      
   I put together a circuit for a laser alarm.   
      
   It does not work.   
      
   There is no way to tell if a design will be successful even if you follow the   
   authors exact directions.   
      
   I will keep plugging away and reading Practical Electronics for Inventors.
