Phreaking: black box
The last click Issue 1
Let's go for a subject not more original than the rest of my zine...
But here there are a few changes, because about the Black Box, I don't agree with everybody.
First of all, a black box is a small cheap assembled device that you put in a black box to not deviate from the rule. It is used to establish a free communication with the guys who call you.
It works quite simply:
When you pick up the phone, it has an impedance of 1000 Ohms which becomes a resistance of 700 Ohms. This change announces a line tap at FT. The black box is then a resistance of 2 KOhms which decreases the impedance of the system. (Many say 1.8 KOhms but I say 2, nah!!) The new impedance is enough to use the line without FT noticing.
But as I said in the warning article, you can't play with this indefinitely.
Here is the schematic of a black box:
Note that the color of the wires is respected and that the Led is completely optional. Anyway, it does not work.
Well, don't forget my warning, and solder well...
