- 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
- for 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.
-
- Materials you will need
- =======================
-
- (1) 9 volt battery with battery clip
- (1) 25-mfd, 15 volt electrolytic capacitor
- (2) .0047 mfd capacitors
- (1) .022 mfd capacitor
- (1) 51 pf capacitor
- (1) 365 pf variable capacitor
- (1) Transistor antenna coil
- (1) 2N366 transistor
- (1) 2N464 transistor
- (1) 100k resistor
- (1) 5.6k resistor
- (1) 10k resistor
- (1) 2meg potentiometer with SPST switch
- Some good wire, solder, soldering iron, board to put it on, box (optional)
-

- 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
- say 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:
-

- Closing statement
- =================
-
- 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,
- leave me mail on:Hi-Times=702/832/7469 Warez House=702/827/9273
