White box plans - make a touch tone phone portable

WHITE BOX PLANS

FROM: THE PIRATE CLUB/1200

EDITED BY: CRACKER JACK

THIS ARTICLE WILL TELL YOU HOW TO CHANGE A NORMAL TOUCH TONE KEYPAD AND
CONVERT IT TO A PORTABLE UNIT. IN ADDITION, WE GIVE THE TOUCH-TONE
FREQUENCIES.

FIRST OF ALL, THE TONES MADE BY A TOUCH TONE TELEPHONE ARE NOT SINGLE
TONES, THEY ARE A COMBINATION OF TWO TONES, MAKING "DTMF" (DUAL TONE
MULTI-FREQUENCY). THE NORMAL TONE TELEPHONE DIALS 12 DIFFERENT SIGNALS,
BUT IS CAPABLE OF DIALING 16 DIFFERENT SIGNALS (SEE BULLETIN ON SILVER
BOXES).

THE POWER REQUIRED BY A KEYPAD IS ABOUT 25 VOLTS, BUT THEY WILL WORK WITH
AS LITTLE AS 15, THEREBY ALLOWING THE USE OF TWO 9- VOLT RADIO BATTERIES.
AS YOU MAY HAVE GUESSED, THEY ARE ALSO DESIGNED TO OPERATE WITH A
TELEPHONE TYPE SPEAKER (AND PHONE LINE), AND NOT THE STANDARD 8-OHM
SPEAKER WHICH NEEDS TO BE USED FOR ADEQUATE VOLUME.  TO ACCOMPOLISH THIS,
WE USE A MATCHING TRANSFORMER, THIS IS ONE OF THOSE MINIATURE ONES
AVAILABLE AT RADIO SHACK.  ENOUGH OF THE THEORY, NOW FOR THE CIRCUIT.

YOU WILL NEED:

A TOUCH TONE KEYPAD
A MINIATURE 1000 TO 8 OHM
   TRANSFORMER (RADIO SHACK # 273-1380)
A STANDARD 8-OHM SPEAKER
TWO 9-VOLT RADIO BATTERIES
TWO 9-VOLT BATTERY CLIPS
A CASE TO PUT IT ALL IN (OPTIONAL)

A FEW CONSTRUCTION NOTES, I SUGGEST THAT YOU SOLDER AND TAPE ALL
CONNECTIONS.  IT IS ALSO IMPORTANT TO READ THIS ENTIRE BULLETIN BEFORE
ATTEMPTING TO CONSTRUCT THIS.

FIRST, CONNECT THE RED WIRE OF THE TRANSFORMER TO EITHER TERMINAL ON THE
SPEAKER.  NOW CONNECT THE WHITE WIRE FROM THE TRANSFORMER TO THE OTHER
TERMINAL ON THE SPEAKER.  NEXT, CONNECT THE RED (POSITIVE) WIRE OF ONE
BATTERY CLIP TO THE BLACK WIRE OF THE OTHER BATTERY CLIP.  NOW CONNECT THE
THE REMAINING RED WIRE ON THE SECOND BATTERY CLIP TO THE GREEN WIRE FROM
THE TOUCH TONE PAD.  CONNECT THE BLUE WIRE FROM THE TOUCH TONE PAD TO THE
ORANGE-AND-BLACK STRIPED WIRE FROM THE TOUCH TONE PAD.  TO THESE TWO
WIRES, NOW CONNECT THE REMAINING BLACK LEAD FROM FIRST BATTERY CLIP.  YOU
HAVE NOW FINISHED THE POWER CONNECTION TO THE KEYPAD.  CONNECT THE BLACK
WIRE FROM THE KEYPAD TO THE BLUE WIRE ON THE TRANSFORMER.  NEXT CONNECT
THE RED-AND-GREEN STRIPED WIRE FROM THE TO THE GREEN WIRE ON THE
TRANSFORMER.  THE BLACK WIRE ON THE TRANSFORMER SHOULD NOT BE CONNECTED TO
ANYTHING, ALONG WITH QUITE A FEW WIRES FROM THE KEYPAD.  THE CONNECTION OF
THE KEYPAD IS NOW COMPLETE.  ALL YOU HAVE TO DO IS CONNECT TWO NINE VOLT
BATTERIES TO THE BATTERY CLIPS, AND YOU'LL BE READY TO GO. YOU MAY WANT TO
MOUNT IT IN A CASE FOR EASY PORTABILITY. NOTE THAT THE SILVER BOX
MODIFICATION CAN BE MADE TO THIS UNIT, ALLOWING COMPLETE REMOTE PHREAKING.
WHEN NONE OF THE BUTTONS ARE PRESSED, THIS UNIT USES NO POWER, THEREBY
ELIMINATING THE NEED FOR A POWER SWITCH, AND EXTENDING THE LIFE OF THE
BATTERIES.

THE FOLLOWING ARE THE FREQUENCY COMBINATIONS GENERATED BY EACH BUTTON ON
THE KEYPAD.
