  32. Introduction:
  33.  
  34. After reading the earlier renditions of schematics for the Pearl Box, I decided that there was an easier and cheaper way of
  35. doing the same thing with an IC and parts you probably have just laying around the house. 
  36.  
  37. What Is A Pearl Box and Why Do I Want One?
  38.  
  39. A Pearl Box is a tone generating device that is used to make a wide range of single tones. Therefore, it would be very easy to
  40. modify this basic design to make a Blue Box by making 2 Pearl Boxes and joining them together in some fashion. 
  41.  
  42. A Pearl Box can be used to create any tone you wish that other boxes may not. It also has a tone sweep option that can be
  43. used for numerous things like detecting different types of phone tapping devices. 
  44.  
  45. Parts List: 
  46.  
  47.      CD4049 RCA integrated circuit 
  48.      .1 uF disk capacitor 
  49.      1 uF 16V electrolitic capacitor 
  50.      1K resistor 
  51.      10M resistor 
  52.      1meg pot 
  53.      1N914 diode 
  54.      Some SPST momentary push-button switches 
  55.      1 SPDT toggle switch 
  56.      9 Volt battery & clip 
  57.      and miscellaneous stuff you should have laying around the house.
