Introduction
|
|||
|
|
===========
|
|||
|
|
|
|||
|
|
The Lunch Box is a VERY simple transmitter which can be handy for all sorts of
|
|||
|
|
things. It is quite small and can easily be put in a number of places. I have
|
|||
|
|
successfully used it for tapping fones, getting inside info, blackmail and
|
|||
|
|
other such things. The possibilities are endless. I will also include the plans
|
|||
|
|
or an equally small receiver for your newly made toy. Use it for just about
|
|||
|
|
anything. You can also make the transmitter and receiver together in one box
|
|||
|
|
and use it as a walkie talkie.

|||

Notes about the schematic
|
|||
|
|
=========================
|
|||
|
|
|
|||
|
|
1. GND means ground
|
|||
|
|
2. The GND near the switch and the GND by the 2meg potentiometer should be
|
|||
|
|
connected.
|
|||
|
|
3. Where you see: )(
|
|||
|
|
()
|
|||
|
|
)( it is the transistor antenna coil with 15 turns of
|
|||
|
|
regular hook-up wire around it.
|
|||
|
|
4. The middle of the loop on the left side (the left of "()") you should run
|
|||
|
|
a wire down to the "+" which has nothing attached to it. There is a .0047
|
|||
|
|
capacitor on the correct piece of wire.
|
|||
|
|
5. For the microphone use a magnetic earphone (1k to 2k).
|
|||
|
|
6. Where you see "[!]" is the antenna. Use about 8 feet of wire to broadcast
|
|||
|
|
approx 300ft. Part 15 of the FCC rules and regulation says you can't
|
|||
|
|
broadcast over 300 feet without a license. (Hahaha). Use more wire for an
|
|||
|
|
antenna for longer distances. (Attach it to the black wire on the fone
|
|||
|
|
line for about a 250 foot antenna!)
|
|||
|
|
|
|||
|
|
Operation of the Lunch Box
|
|||
|
|
==========================
|
|||
|
|
|
|||
|
|
This transmitter will send the signals over the AM radio band. You use the
|
|||
|
|
variable capacitor to adjust what freq. you want to use. Find a good unused
|
|||
|
|
freq. down at the lower end of the scale and you're set. Use the 2 meg pot. to
|
|||
|
|
adjust gain. Just fuck with it until you get what sounds good. The switch on
|
|||
|
|
the 2meg is for turning the Lunch Box on and off. When everything is adjusted,
|
|||
|
|
turn on an AM radio adjust it to where you think the signal is. Have a friend
|
|||
|
|
lay some shit thru the Box and tune in to it. That's all there is to it. The
|
|||
|
|
plans for a simple receiver are shown below:

This two devices can be built for under a total of $10.00. Not too bad. Using
|
|||
|
|
these devices in illegal ways is your option. If you get caught, I accept NO
|
|||
|
|
responsibility for your actions. This can be a lot of fun if used correctly.
|
|||
|
|
Hook it up to the red wire (I think) on the fone line and it will send the
|
|||
|
|
conversation over the air waves. If you have any problems or are confused,
|
|||
