You are just one step away from being in show business

This project utilizes the fiber optic bundle which you assembled in Experiment 17, and later
used in Project 1 and 2. This time you will create a fiber optic display which will project the initials of
your name on the wall of a darkened room.

• Cut a circle 2.22 cm in diameter from cardboard.
• Print your initials in the center of the cardboard.
Each letter should be about 6 mm (.25 inch) in
diameter.
• Using the sewing pin, poke holes through the
cardboard, following the shape of your initials. Try
to space them 1 mm (.04 inches) apart or closer,
and keep the pin perpendicular so the pattern of
your initials is accurately copied to the other side of
the cardboard.
• Insert a fiber from your multifiber bundle into each
hole on the side marked with your initials (back).
Position the fibers so they stick out slightly on the
other side (about 0.5 mm or .02 inches) and are
fairly even with each other.
• Apply Super Glue ® glue sparingly to the back of the
cardboard (where you printed your initials) to hold fibers in place, and let the glue dry.
• Pull the portion of the fiber bundle with the heat shrink through the smaller diameter acrylic
tube until the cardboard contacts the cylinder end. Center the cardboard to the acrylic cylinder
and secure with Super Glue
® .
• If you want your initials to be projected in color, glue any of the colored film (included in the kit)
over the fiber ends sticking through the front of the cardboard.
• Place three small balls of hot glue (or silicone) on either end of the larger acrylic cylinder, then
attach the lens to cylinder end,center ing to each other. Set aside to let the glue (silicone) dry.
• Insert the front of the fiber array into the acrylic cylinder until it is about 5 cm away from the
lens.
• Insert the free end of the fiber bundle into the hole in the boot. Install the rubber boot on the
penlight.
• Turn the penlight on and dim the room lights.
• Position yourself and the acrylic cylinder about 1.5 meters (5 feet) from a wall. Point the acrylic
cylinder toward the wall and slide the cardboard back and forth in the acrylic tube until your
initials are in sharp focus on the wall.
