TIPS

(Continued from page 26)

FIBER

OPTICS

CAN

PUT

LIGHT WHERE

YOU WANT

IT -EVEN AROUND

CORNERS

Use

a soldering

gun

on a component

you

can-

not see, and

more

harm

than

good

can come

of your work, especially

if the

component is

a transistor

which

is easily

damaged by heat.

There are plastic fi-

ber optic

light guides

available that will

light

your

way

with a

pencil

-thin

beam of

light

so that

you can

work in the

tightest

and most poorly lit

areas

of

a chassis.

When light is focused

on one end of a light

guide, it is transmit-

ted to

the other end with

very little loss in

intensity, even

if

the

guide

is bent in a circle.

A

small penlight

flashlight

can

be used as a

light source,

and an alligator clip

can be

taped to the

light

guide

so that you

don't

have to hold

the

guide while you're

working.

One source

of fiber optic light guides

is Ed-

mund Scientific Co.,

Barrington, N.J.; they

cost about

65

cents a foot. -E. S. Connors

CONVERT

BALL -POINT PEN

TO SOLDER HOLDER AND

FEEDER

Are

you

muscle -bound from juggling

a

solder-

ing gun

in

one hand

and a

1 -lb. roll

of solder

in

the

other? You

can

lighten the

load in at

least one hand with a ball -point

pen

and an

empty thread

spool. Remove

the

top, cart-

ridge, and

spring from

the ball

-point

pen, and press -

fit

the plastic

pen shell into

the hole

in

the

spool. It may

be necessary

to ream the hole

in

the

spool

for

the shell

to

fit.

Glue

the shell

and spool

together. Now,

wrap a small

supply of

solder

onto

the spool,

and

thread the

free end of the solder through

your

new solder feeder as shown.

WHITE

PAINT KEEPS

ELECTRONIC EQUIPMENT COOL

If you have to run

your equipment

while

it is

exposed

to the

sun,

chances are that the

com-

bined heat from

the inside and from

the out-

side

will

cause

tuned circuits

to

drift, shorten

component

life,

and induce other thermal

problems.

A

coat of white paint applied

to the

outer

surfaces of your

equipment

cabinet will

reflect

a

large

portion of the sun's heat

and

reduce

the

heat level

within the cabinet.
