Assembling The Zapper

Assembling The Zapper

1. You will be using the lid of the shoe box to mount the
components. Save the box to enclose the finished project.
2. Pierce two holes near the ends of the lid. Enlarge the holes
with a pen or pencil until the bolts would fit through.
Mount the bolts on the outside about half way through the
holes so there is a washer
and nut holding it in place
on both sides. Tighten.
Label one hole “grounding
bolt” on the inside and
outside.
3. Mount the 555 chip in the
wire wrap socket. Find the
“top end” of the chip by
searching the outside surface carefully for a cookie-shaped
bite or hole taken out of it. Align the chip with the socket
and very gently squeeze the pins of the chip into the socket
until they click in place.
4. Make 8 pinholes to fit the wire wrap socket. Enlarge them
slightly with a sharp pencil. Mount it on the outside. Write
in the numbers of the pins (connections) on both the outside
and inside, starting with number one to the left of the
“cookie bite” as seen
from outside. After
number 4, cross over
to number 5 and
continue. Number 8
will be across from
number 1.
5. Pierce two holes ½
inch apart very near
to pins 5, 6, 7, and 8. They should be less than 1/8 inch
away. (Or, one end of each component can share a hole
with the 555 chip.) Mount the .01 uF ca

pacitor near pin 5
on the outside. On
the inside connect
pin 5 to one end of
this capacitor by
simply twisting
them together.
Loop the capacitor
wire around the
pin first; then twist with the long-nose pliers until you have
made a tight connection. Bend the other wire from the
capacitor flat against the inside of the shoe box lid. Label it
.01 on the outside and inside. Mount the .0047 uF capacitor
near pin 6. On the inside twist the capacitor wire around
the pin. Flatten the wire from the other end and label it
.0047. Mount the 3.9 KW resistor near pin 7, connecting it
on the inside to the pin. Flatten the wire on the other end
and label it 3.9. Mount the 1 KW resistor and connect it
similarly to pin 8 and label it 1K.
6. Pierce two holes ½ inch apart next to pin 3 (again, you can
share the hole for pin 3 if you wish), in the direction of the
bolt. Mount the other 1 KW resistor and label inside and
outside. Twist the connections together and flatten the remaining
wire. This resistor protects the circuit if you
should accidentally short the terminals. Mount the 3.9KW
resistor downward. One end can go in the same hole as the
1K resistor near pin 3. Twist that end around pin 3 which
already has the 1K
resistor attached to
it. Flatten the far
end. Label.
7. Next to the 3.9KW
resistor pierce two
holes ¼ inch apart
for the LED. No

tice that the LED has a positive and negative connection.
The longer wire is the anode (positive). Mount the LED on
the outside and bend back the wires, labeling them + and -
on the inside.
8. Near the top
pierce a hole for
the toggle
switch. Enlarge
it until the shaft
fits through from
the inside.
Remove nut and
washer from
switch before
mounting. You may need to trim away some paper with a
serrated knife before replacing washer and nut on the
outside. Tighten.
9. Next to the switch pierce two holes for the wires from the
battery holder and poke them through. Attach the battery
and tape it to the outside.
