Have you ever considered buying one of those hi powered microphones often
|
|||
|
|
seen in eletronics magazines, but thought it was to much to buy and to small to
|
|||
|
|
card? The circuit shown in this file will provide you with the information to
|
|||
|
|
build one for a lot less money.
|
|||
|
|
These audio eavesdropping devices are probably one of the hottest items in
|
|||
|
|
the underground due to their ability to pick up voices through thick walls.
|
|||
|
|
You can also attach the speaker wires to a tape recorder and save all the
|
|||
|
|
conversation. As one can see these are great for blackmailing a teacher,
|
|||
|
|
classmate, principal, neighbor, or whoever you seek services from...

This handy little circuit is the key to generating THOUSANDS of volts of
|
|||
|
|
electricity for warding off attackers (notice the plural). It generates it
|
|||
|
|
all from a hefty 6-volt source and is easily fit into a tubular casing.
|
|||
|
|
Originally used as a fence charger, this circuit can be put to other uses such
|
|||
|
|
as: charging a whole row of lockers at school, a row of theater seats, or a
|
|||
|
|
metal bleacher set in the gym. More on this later.
|
|||
|
|
|
|||
|
|
To build this, all you need is a GE-3 transistor, a 6.3-volt transformer, and a
|
|||
|
|
handful of spare parts from old radios. The ammount of shock you wish to
|
|||
|
|
generate is determined by the setting of potentiometer R1, a 15,000 ohm
|
|||
|
|
variable resistor. Hint: for maximum shock, set R1 at maximum!

WIRELESS TRANSMITTER PLANZ
|
|||
|
|
|
|||
|
|
This is a tiny transmitter that consists on a one colpitts oscillator that
|
|||
|
|
derives it's power from the phone line. Since the resistance it puts on the
|
|||
|
|
line is less than 100 ohms, it has no effect on the telephone performance, and
|
|||
|
|
can not be detected by the phone company, or the tappee. Since it is a
|
|||
|
|
low-powered device using no antenna for radiation, it is legal to the FCC.
|
|||
|
|
(That is it complies with part 15 of the FCC rules and regulations). It,
|
|||
|
|
however is still illegal to do, it's just that what you're using to do it is
|
|||
|
|
legal. This is explained later in part 15... "no person shall use such a device
|
|||
|
|
for eavesdropping unless authorized by all parties of the conversation" (then
|
|||
|
|
it's not eavesdropping is it?). What this thing does, is use four diodes to
|
|||
|
|
form a "bridge rectifier". It produces a varying dc voltage varying with the
|
|||
|
|
auto-signals on the line. That voltage is used to supply the the voltage for
|
|||
|
|
the oscillator transistor. Which is connected to a radio circuit. From there,
|
|||
|
|
you can tune it to any channel you want. The rest will all be explained in a
|
|||
|
|
minute....

|
L1 may be constructed by winding approximately 40 turns of No. 36
|
|||
|
|
enamel wire on a mega-ohm, 1/2 watt resistor. The value of L1 is
|
|||
|
|
not critical. L2 can be made by wrapping 5 turns of No. 20 wire
|
|||
|
|
around a 1/4 inch form. After the wire is wrapped, the form can
|
|||
|
|
be removed. Just solder it into place on the circuit board. It
|
|||
|
|
should hold quite nicely. Also be sure to position Q1 so that the
|
|||
|
|
emitter, base, and collector are in the proper holes. The
|
|||
|
|
schematic should be pretty easy to follow. Although it has an
|
|||
|
|
unusual number of grounds, it still works.

The odd thing about this bug that we haven't encountered yet, is that it is put
|
|||
|
|
on only one wire (either red or green) so go to the box, remove the red wire
|
|||
|
|
that was ALREADY on screw
|
|||
|
|
1 and attach it to wire 'A' of the bug. Then attach
|
|||
|
|
wire 'B' to the screw itself. You can adjust the frequency which it comes out
|
|||
|
|
on the FM channel by either smooshing, or widening the coils of L2. It takes a
|
|||
|
|
few minutes to get to work right, but it is also very versatile. You can change
|
|||
|
|
the frequency at will, and you can easily record off your radio.
