BLACK BOX PLANS
|
||
|
||
HERE IS HOW YOU CONSTRUCT A BLACK BOX.
|
||
|
||
WHEN YOUR PHONE IS JUST SITTING THERE DOING NOTHING THE
|
||
VOLTAGE THROUGH THE PHONE LINE IS ZERO. THEN IF SOMEONE CALLS
|
||
YOU (FOR SOME STRANGE REASON) AND THE PHONE IS RINGING. THE
|
||
VOLTAGE JUMPS TO 48 VOLTS WHICH TELLS MA BELL TO STAND BY IF YOU
|
||
SHOULD PICK UP SO SHE CAN BILL YOU. WHEN YOU EVENTUALLY PICK UP
|
||
THE PHONE, THE VOLTAGE DROPS TO 10 VOLTS AND THE BILLING STARTS.
|
||
WHAT A BLACK BOX DOES IS KEEPS THE THE VOLTAGE AS 36 VOLTS,
|
||
THEREFORE THE INCOMING CALLER NEVER GETS BILLED (INGEINIOUS)
|
||
|
||
THE ORIGINAL BLACK BOX WAS CREATED BY AN EX-BELL EMPLOYEE WHO
|
||
WENT BY THE NAME "CAPTAIN CRUNCH". HE GOT HIS NAME FROM THOSE
|
||
LITTLE WHISLES YOU GOT IN BOXES OF CAPTAIN CRUNCH BECAUSE THEY
|
||
EMITED A TONE THAT WAS EQUAL TO A COIN.CAPTAIN CRUNCH JUST
|
||
ANNOUNCED HIS RETIREMENT FROM PHREAKING WHEN HE WAS RELEASED
|
||
FROM A CALIFORNIA JAIL. HE WAS CAUGHT WITH A BLUE BOX.
|
||
|
||
CONSTRUCTION OF A
|
||
BLACK BOX
|
||
|
||
1] A 36 VOLT ZENER DIODE.
|
||
2] A CERAMIC OR MYLAR CAPACITOR OF 0.1 MICROFARAD.
|
||
3] A ELECTROLYTIC CAPACITOR OF 1.0 MICROFARAD.
|
||
|
||
YOU CAN GET THESE AT YOUR LOCAL RADIO SHACK DEALER.
|
||
|
||
FIRST YOU HAVE TO OPEN UP YOUR PHONE.YOU SHOULD NOTICE THREE
|
||
WIRES COMING IN FROM THE BACK OF THE PHONE, A GREEN, RED, AND
|
||
YELLOW. MOST OF THE TIME THEY CAN DIFFER.DON'T WORRY ABOUT THE
|
||
YELLOW WIRE, WE WILL NOT BE USING THIS.YOU WILL NEED TO FIND THE
|
||
MOST POSITIVE OF THE REMAINING TWO WIRES.(ALMOST ALWAYS THE
|
||
GREEN WIRE). NOW CONNECT THE BANDED END OF THE ZENER DIODE TO
|
||
THE MORE POSITIVE OF THESE TWO WIRES. "IN SERIES". YOU HAVE JUST
|
||
COMPLETED THE FIRST STEP. FOR THE SECOND STEP YOU NEED A
|
||
CERAMIC OR MYLAR CAPACITOR OF 0.1 MICROFARAD. YOU CONNECT THIS
|
||
"IN PARRALLEL" ACROSS THE DIODE. THIS IS NEEDED TO ALLOW THE
|
||
DIODE TO PASS VOICE SIGNALS. NOW FOR THE FINAL STEP TAKE YOUR
|
||
ELECTROLYTIC CAPACITOR OF UP TO ONE MICROFARAD WITH ITS '+' END
|
||
CONNECTED TO THE BANDED END OF THE DIODE AND THE OTHER END
|
||
SHOULD BE CONNECTED TO THE ANODE END OF THE DIODE. MA BELL IS
|
||
NOT TOTALLY OBLIVIOUS TO THIS.IF THE PHONE RINGS FOR ABOUT A
|
||
HALF-HOUR THEY WILL THINK SOMETHING IS WRONG AND BILL YOU
|
||
ANYWAY. WHEN USING A BLACK BOX,YOUR PHONE WILL CONTINUE RING
|
||
EVEN THOUGH YOU PICKED IT UP. YOU HAVE TO MAKE A SWITCH TO
|
||
CONNECT ONE OF THE RINGER WIRES.THAT WILL SHUT IT OFF. THAT'S
|
||
IT! HAVE PHUN!!!!!!!!!!!!!!!!
