case, maintenance is done on the spot, with screwdriver and pliers, while in the case of electronic switching, it can be done remotely, by
computer, from a central point, making it possible to have only one or two technicians on duty at a time at each switching center. The
development program, when the final figures were added up, was found to have required a staggering four thousand man-years of work at
Bell Labs and to have cost not $45 million but $500 million!
117.The Lunch Box by The Jolly Roger
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.
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)
Schematic for The Lunch Box
This may get a tad confusing but just print it out and pay attention.

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:

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 on the phone line and it will send
the conversation over the air waves.
118.Olive Box Plans by The Jolly Roger
This is a relatively new box, and all it basically does is serve as a phone ringer. You have two choices for ringers, a piezoelectric
transducer (ringer), or a standard 8 ohm speaker. The speaker has a more pleasant tone to it, but either will do fine. This circuit can also be
used in conjunction with a rust box to control an external something or other when the phone rings. Just connect the 8 ohm speaker output to
the inputs on the rust box, and control the pot to tune it to light the light (which can be replaced by a relay for external controlling) when the
phone rings.
