Your personal fiber optic "constellation "
.................................................................................................................................
Optical fibers are often used in displays to create or enhance special posters or maps. Now you
will see how fiber optics can add visual effects to a map of the stars.

* The star map has a pattern representing the stars and constellations in the earth's northern
hemisphere. Each small dot is the location of a star. Select no more than 100 stars that you wish
to illuminate in this project.
• Remove the backing from the constellation map and center it on the Foamcor ® board.
• With a needle, punch a hole in the map at each dot, large enough for the 250 µm (.010 inch)
fiber to go through.
• If using a hot glue gun, turn it on now.
• Place the multifiber fiber bundle on the back side of the map. From the rear, insert one fiber at a
time into the holes punched in the map. Insert each fiber until its tip is flush with the front of the
cardboard. Adhere in place with the glue gun (or silicone).
• Repeat, inserting a fiber into map for every star. (You will have fibers left over.)
• Insert the fiber bundle into the rubber boot until the ends extend about 1 cm (3/8 inch) inside.
• Fit the rubber boot over the penlight.
• Punch holes in the lower portions of the map
marked with an "X" using a pencil or large nail.
• Position the penlight behind the four holes in the
map and fasten it in place with the twist ties
provided.
• Cut a 16 cm (6 inch) length of the jacketed optical
fiber, using a single-edge razor blade or sharp
knife. Glue the fiber to the back of the star map as
shown. This fiber will be used as a hanger for your
map.
• Turn the penlight on to view your completed
project.
