==Phrack Inc.== Volume Three, Issue 28, File #5 of 12 /////////////////////\\\\\\\\\\\\\\\\\\\\\ || || || A Real Functioning PEARL BOX Schematic || || || || Written, Tested, and Used || || || || by Dispater || || || || July 1, 1989 || || || \\\\\\\\\\\\\\\\\\\\\///////////////////// Introduction: After reading the earlier renditions of schematics for the Pearl Box, I decided that there was an easier and cheaper way of doing the same thing with an IC and parts you probably have just laying around the house. What Is A Pearl Box and Why Do I Want One? 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 modify this basic design to make a Blue Box by making 2 Pearl Boxes and joining them together in some fashion. 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 used for numerous things like detecting different types of phone tapping devices. Parts List: CD4049 RCA integrated circuit .1 uF disk capacitor 1 uF 16V electrolitic capacitor 1K resistor 10M resistor 1meg pot 1N914 diode Some SPST momentary push-button switches 1 SPDT toggle switch 9 Volt battery & clip and miscellaneous stuff you should have laying around the house.
