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....

C1 | 47-Pf ceramic disk capacitor
|
||
C2,C3 | 27-Pf mica capacitor
|

CR1,CR2,CR3,CR4 | germanium diode 1n90 or equivalent
|
||
R1 | 100 ohm, 1/4 watt 10% composition resistor
|
||
R2 | 10k, 1/4 watt 10% composition resistor
|
||
R3 | .7k, 1/4 watt 10% composition resistor
|
||
L1 | 2 uH radio frequency choke (see text)
|
||
L2 | 5 turns No.20 wire (see text)
|
||
Q1 | Npn rf transistor 2N5179 or equivalent
|
||
-----------------------------------------------------------------
|
||
|
||
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.
