- As everyone knows, text schematics suck. That is why I have deemed it
- necessary for someone to create a standard electronic character set. Maybe
- I'll work on it but if someone comes up with one, all hail the mighty
- character. Ideas for its construction are like having standard characters
- represent electronic symbols like this...
-
- 'Q' = Left side of horizontal resistor
- 'E' = Right side of horizontal resistor
- 'R' = Horizontal connection
- 'T' = Vertical connection
- 'Y' = Horizontal capacitor, not polarized
- So, here is the circuit.

- Now for an explanation. First, a parts list:
- Resistors: 47k Ohm, 10k Ohm, 1k Ohm
- Potentiometers: 50k Ohm M Pot
- Capacitors: 0.1 UF
- Semiconductors: PNP - 2N3906 TRANSIS TOR, NPN - 2N3904 transistor, 1N4005 diode
- Battery: One 6 volt or four 1.5 volt, a switch would be nice
- Realy: I'm using a little blue 4.5 volt relay with double pole, double
- throw contacts. It's in a DIP arrangement and I can't remeber the
- Radio Shack number.
- Misc: Various sizes of jacks for interfacing the tape recorder, battery,
- telephone line, etc...
- BATTERY, TELEPHONE L
- I built this thing four times on a bread board and twice on a PC board before
- I got it to work to my satisfaction. I suggest you build it on a bread board
- Last minute changes always kill me...
- Well, assemble the parts as shown in the shematics. A word about cryptic codes
-
-
- - Is a polarized capacitor with the negative end
- pointing right
-
-
- --> Is the diode with the cathode pointing right
-
-
-
- -+- On NPN the arrow on the emitor points out. On PNP
- it points in. The leads are designated, 'B' for
- base. 'E' for emitor and 'C' for collector.
-
- 2N3904 AND 2N3906'S are easy to come by. Radio Shack sells boxes of 15 for
- under 5 buckd. They're fun to play with as they are good general purpose
- transistors. I can't guarentee good results if you use other transistors, but
- it would probably work. 05 is the diode and can be changed for any other diode
- that has approximately the same ratings, 100 prv minimum, 1 amp, etc...
-
- I recommend Durecel batteries for the sole reason that they last longer than
- than regular carbon batteries. But if u have a 115 AC outlet nearby u could
- use a 6 volt power pack.

- HOW TO USE A COLOR BOX...
-
- Now that you've made the the box mentioned above, you may want to know what to
- do with it. Many good phreaks may not want to bother reading this message, as
- the uses are quite obvious. But this is what I think it could bu used for.
-
- Well, say you suspect your girlfriend cheating on you... hmmm, that actually
- is a quite frivout use, but is a possibilty...
-
- The scenerio is this:
- You've been dialing numbers in your exchange and you've found a couple
- computers but you don't know any passwords... what you'd do is call up CN/A
- and get the location of the number you want to check out. Then, you'd go to
- wherever the place is and check out where the service enters the building. Now
- here's where the sheep get seperated from the goats. Somehow you have to get
- at the two wires making up the line. You could break in or strip the wires on
- the pole. Anyway, you get some bare wire and attach the box across these wires
- Then, you put your tape in and press record. Turn your box on and forget
- about it for a couple days. Now, serveral things could happen.
- One - someone might find the box and call hte phone cops.
- Two- The dude might call out on the line in which case the numbers will be
- recorded on the tape.
-
- Three - The guy might get incoming calls which will be recorded.
- So, you get your box back and see what's on the tape. If it's a computer, then
- you play the tones back into your demodulator and see what's going on. You
- will get all the passwords, acess parameters and everything that went on the
- line.
-
- Hmmm, did I remeber to say what the four pairs of wires coming out of the
- are? One is the battery, one is for the line which you are tapping into, on
- goes to the microphone of the recorder, and the last pair goes to the
- recorder's remote jack.
