-=ð Converting a Tone Dialer into a Red Box ð=-
|
|
|
|
Introduction...
|
|
---------------
|
|
As of 1/1/94 Radio Shack discontinued thier old dailer that I used to
|
|
make Red Boxes... Due to the fact that I was making a great deal of money
|
|
selling them I was quite distressed. But as of a week ago they came out
|
|
with a brand new one that works just fine and looks a hell of a lot better.
|
|
So I am gonna tell you how to use it to make yourself a Red Box or 70...
|
|
|
|
Stuff...
|
|
--------
|
|
To make this modification you will need a Radio Shack Pocket Tone
|
|
Dialer part #43-146 ($24.95), a Phillips screwdriver, a flat bladed
|
|
screwdriver, a soldering iron, a pair of long nose pliers, a pair of wire
|
|
cutters and a 6.5536 MHz (megahertz) crystal.
|
|
|
|
Process...
|
|
----------
|
|
Orient the dialer with the keypad down and the speaker at the top.
|
|
Remove the battery compartment cover to expose four screws. Remove these
|
|
four screws and the two on the top of the dialer near the speaker. There
|
|
are four plastic clips that are now holding the two halves of the dialer
|
|
together. Push on the two bottom clips near the battery compartment and
|
|
pull up to seperate the bottom part. Now slide a flat screwdriver into the
|
|
seam on the left starting from the bottom and moving towards the top.
|
|
|
|
When the two halves separate, slide the speaker half underneath the
|
|
other half while being careful not to break the wires connecting the two.
|
|
Locate the cylindrical metallic can (it's about half an inch long and an
|
|
eighth of an inch in diameter) and pull it away from the circuit board to
|
|
break the glue that holds it in place. Unsolder this can, which is a
|
|
3.579545 MHz crystal, from the circuit board.
|
|
|
|
The hard part of this modification is getting the new crystal to fit
|
|
properly. Bend the three disk capacitors over,[And out of the way the best
|
|
you can, making room for the new crystal. You may need to remove the screw
|
|
in the way as well.] Since the 6.5536 MHz crystal is probably much bigger
|
|
than the crystal you are replacing, you will need to bend the leads on the
|
|
new crystal so that they will match up will the pads on the circuit board.
|
|
Place the new crystal on the circuit board by soldering it in place. As an
|
|
added touch you might peel he QC sticker off of the PC board and place it
|
|
on top of the crystal. Now carefully snap the two halves back together
|
|
while checking to make sure that none of the wires are getting pinched or
|
|
are in the way of the screw holes. Put the case screws back on and insert
|
|
three AAA batteries into the battery compartment.
|
|
|
|
Your dialer is now ready to test. Switch the unit on. The LED on the
|
|
dial pad side should be lit. Set the lower slide switch to STORE mode.
|
|
Press the MEMORY button on the dial pad. Press the * key five times.
|
|
Press the MEMORY key again and then press the P1 key. A beep tone when any
|
|
key is pressed and a long beep should sound after the P1 key has been
|
|
pressed to indicate that the programming sequence was performed correctly.
|
|
|
|
Switch the unit into DIAL mode. press the P1 key, and five tone
|
|
pulses that sound remarkably like coin tones should come out of the
|
|
speaker. I usually program P1 to be four quarters (insert one or two
|
|
PAUSE's between each set of five tones), P2 to be two quarters, and P3 as
|
|
one quarter.
|
|
|
|
Of course, you can no longer use the unit to generate touch tones.....
|
|
|
|
Use...
|
|
------
|
|
Now all you do is pick up the pay phone dial the number and when the
|
|
Recording comes on to tell you how much money to deposite, Hold the speaker
|
|
up to the mouth piece and press the memory key. That is it... You are set.
|
|
|
|
Reference...
|
|
------------
|
|
The crystal is available from Fry's Electronics in Freemont, CA for
|
|
$2.99 plus the charge for UPS Red or Blue. Their number is 510-770-3797.
|
|
I would suggest buying five, some for future use and some just in case you
|
|
cut the leads too short when trying this project.
|
|
|
|
Oppertunity...
|
|
--------------
|
|
Welp... Now that you have this lovely device, you have two choices:
|
|
|
|
1. If you are on the go or have a lap top call every where for free.
|
|
|
|
2. Sell them to your friends... Show them one and they are hooked. Sell
|
|
them for like $250 and if they complain just explian to them that they
|
|
can make like five times that in free calls.
