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. ^ TELEPHONE LINE ^ \ \ \ 47K 10K 1N4005 \ +--/\/\/--+--/\/\/--+--> + \ \ 50K \ \ -- (RELAY SWITCH, N.O.) +------------/\/\/---------+-------O O \ ^ \ \ \ \ \ 0.1 UF \ \ ----O MIC O \ \ -- (RELAY SWITCH, N.O.) \ +-----------+ +-O O-+ \ \ \ \ \ \ -+- 6 VOLTS \ \ \ PNP, 2N3906 --+-- \ O REM O C -+- E \ \ / ------+ \ "BEHIND GLASS, THERE'S \ \ \ A REAL BLADE OF GRASS!

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.
