By Fabulist /// ENIGMA /// 1992. .THE INFORMATION IS FOR THE GREEK TELEPHONE NETWORK BUT THEY CAN BE EASILY CONVERTED FOR USING THEM IN OTHER COUNTRIES Black Box is a little device which is beeing used by phone freaks (phreaks!) so that the one who calls you,won't pay anything.That's only FOR 1 MINUTE in MOST places,but NOT everywhere.In northen Greece ,as far as i know, 1 minute was firstly used in 1992...Pity...The way the boxy works is simple : it makes the telephone center beleive that your phone is still ringing and that's why NO charge is made! ;-) NOTICE : PLEASE DON'T call youself a "phreak" before you have managed to BUILD at LEAST a WORKING Black BOX!! Materials Needed 1st) A phone device 2nd) A 2.7K Ohm resistor 1/2 Watt (colors : red purple red ,which means 2 + 7 + the numbers of zeros at the end ... 2+7+00 Ohm.You will probably find a silver or gold color which represents the accuracy of the resistor. Not really needed but you must put it to the right side and read the colors from the left...) 3rd) A little switch with 3 poles (SPDT?) 4rth) A LED (Light Emitting Diode) 5th) A soldering iron 6th) A screw driver Construction Choose a small and portable phone device and make all your telephone lines in your house easy to modify.This will help you to use many boxes and/or normal phones without fass.Just plug and use! Now open the back of the phone.You will probably find a mess of wires and electronic componends.Ignore everything and look for a GREEN (tip) and a RED (ring) wire,which are coming in from the inlet.The colors may be different (usually they arent) so be carefull.Leave GREEN as it is and unsolder the RED one... 1st SHEMATIC (Without a switch.The Box is always on.) ... ..GREEN ..REDRESISTORLED ..2nd SCHEMATIC (With a switch.LED on BOX on) . GREEN . .. The. thing represents the switch! . RED .. ResistorLED . *WARNING* 60 Volts CAN GIVE QUITE A SHOCK.BE CAREFULL.ALSO ANY CONNECTION BETWEEN THE POLE IN THE MIDDLE AND THE POLE IN THE RIGHT SIDE OF THE SWITCH CAN BE DANGEROUS! . .. . = Joined RED ... = Not Joined Notice the space here! Your Black Box is Ready! Avoid using it a lot , because AC voice signals in DC can help the operators find out what's going on! Finally I recomend testing of the Volts in the line when the phone is doing nothing,when the phone is in use,when the phone is ringing etc because it will help you understand how the boxy works and how others boxes can be build.A good way to test the little thing is by calling it from a phone booth. The 1st (?) Greek Black Box was tested by BAYERNPOWER ! I thank him a lot! Phreak 'em up... And don't forget that..."When ur good nobody knows that ur there"...
