Hey, my verizon cell phone service was cut
off when I could only pay $800 instead of
the $1000 I owed. Is there a way to use the
cell I have and make calls without paying
for service? And or can I make a payphone
look like it is coming from my phone?

use a program called AUDACITY to generate the tones – then use your ipod and headphones

oops meant DSP stuff re: java
sound processor stuff

for whatever it’s worth, I was able to implement this in Java using the Javax JSP stuff:
************************************************

package org.drg00n.util.dtmf;

import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.SourceDataLine;

/*Implement a DTMF dialer with javax’s DSP
* Tone tables are in tones.java
*/

public class DTMF {

public static void generateTones(float hz1, float hz2, int msecs, int volume)
throws Exception {
float frequency = 44100.0F;
int samplesize = 8;
int channels;
boolean signed = true;
boolean bigendian = false;
byte[] buf;
double ttpi = (2.0 * Math.PI);
AudioFormat format;
buf = new byte[2];
channels = 1;
format = new AudioFormat(frequency, samplesize, channels, signed,
bigendian);
SourceDataLine sdl = AudioSystem.getSourceDataLine(format);
sdl.open(format);
sdl.start();
for (int i = 0; i < msecs * frequency / 1000; i++) {

double angle = i / (frequency / hz1) * ttpi;
double angle2 = i / (frequency / hz2) * ttpi;
buf[0] = (byte) (((Math.sin(angle)) + (Math.sin(angle2))) * 10);
sdl.write(buf, 0, 1);
}
sdl.drain();
sdl.stop();
sdl.close();
}
}

********************************************
then create a class for the coins using your data on the frequencies and times for each coin:
********************************************

package org.drg00n.util.dtmf;

public class payphone {

public static void qaurter() throws Exception {
DTMF.generateTones(1700, 2200, 33, 100);
DTMF.generateTones(0, 0, 33, 100);
DTMF.generateTones(1700, 2200, 33, 100);
DTMF.generateTones(0, 0, 33, 100);
DTMF.generateTones(1700, 2200, 33, 100);
DTMF.generateTones(0, 0, 33, 100);
DTMF.generateTones(1700, 2200, 33, 100);
DTMF.generateTones(0, 0, 33, 100);
DTMF.generateTones(1700, 2200, 33, 100);
DTMF.generateTones(0, 0, 33, 100);
}

public static void dime() throws Exception {
DTMF.generateTones(1700, 2200, 66, 100);
DTMF.generateTones(0, 0, 66, 0);
DTMF.generateTones(1700, 2200, 66, 100);
}

public static void nickle() throws Exception {
DTMF.generateTones(1700, 2200, 66, 100);
}
}

************************************************
then you call the coin you want and it beeps out of the sound card:

a main class to beep the coin tones:
************************************

package org.drg00n.util.dtmf;

public class dialer {

public static void main(String[] args) {

/*
* Dial some DTMF Tones:
*/

try {

// payphone.dime();
// payphone.nickle();
payphone.qaurter();

} catch (Exception e) {
e.printStackTrace();
}
}

}

Just the other day I found a semi-broken pay phone that didn’t take money, the mechinism must have been broken. So when I played my red box, it would drop the played ammount :]. Cleaned that thing right out, went into the store it was at and bought a lot of stuff. They’ll never know.

Neat site.
Back in the 70′s there was a publication called TEL, Telephone Electronics Line.
Do you know of any online copies of TEL around?
I could kick myself for dumping a pile of issues way back when.

I dusted off and tried my redbox outside of a circle k gas station in southwest, Florida and it dumped out 75 cents. I was so excited that I ran away and didnt even try to make a call :)

YakBak came out when i was about 12 and i never paid for calls again, i bought the more expensive one with a three sound memory, and a bucketload of distorion effects and silly sounds, tho simple this worked tons better then the homemade boxes my friends made.

And it worked for almost a decade.

Hey Mikey, you know that you can snip a few wires in the back of the phone that has a muted mouthpiece and you will be abble to use it. Look around on http://www.hellboundhackers.org in the articles and there are other good ones.

Rat Shack apparently hasn’t sold parts in years. No crystals, no dialers, no redb0xx0rz. I’d suggest other sources.

Nice info! Too bad red boxes haven’t worked for years.

Sadly In Toronto all the Bell pay phones mute the mouth piece.

How can i build a blue box to generate 2600mhz tone?
