How to Light Up Your Walls with Stars

Everybody loves the stars. Well, I certainly do. As a child I'd spend hours outside during summer nights marveling at the seemingly endless amount of sparkling dots spanning the sky. Maybe you have children of your own and want to create a sparkle in their eyes, or in your own. This tutorial will provide a basic method of bringing the stars inside—at least, in part.

Parts & Tools

This project is very simple. All you need is:

Loose fiber optics (available on eBay or Amazon, see Fig. 1)
LightBox
A 5V power supply

A few tools are needed:

Needle or very thin punch
Wire cutters
Tape

Step 1: Plan Your Stars

I'll be adding stars to a vertical wall, but if you're adding yours to the ceiling, there's no difference in the procedure.

Start plotting random but uniformly spaced dots on the surface of choice using a pencil. This can take a while...be patient!

Step 2: Poke the Holes

This can be fast and easy if you have a punch, or really tedious if you're using a needle. The trick is to be as careful with the front-face of the surface as possible, as any damage/frayed edges will reveal the location of the star-hole when the room is lit.

Step 3: Tape and Feed the Fibers

Using some scotch tape, fold a small piece of tape over each end of the fibers. This is important as it will prevent the fibers from going all the way through the wall when feeding them.

Now, feed the fibers through the holes (opposite end to the tape).

Then pull each one from the other side until the tape reaches the wall.

Step 4: Fasten and Cut

Using some heavy-duty tape, gently fasten the loose fibers to the inside wall. This prevents the fibers from falling out or malfunctioning.

Once each fiber is taped, organize the strands into several "ropes." This makes the fibers easier to manage when running them into the LightBox.

Step 5: Break Off Extra Fibers

Heading over to the front-facing wall, snap off the extra taped ends so the fibers are flush with the wall surface.

Step 6: Sand the Holes

Using very fine sandpaper or a sanding sponge, gently sand off any protruding edges or fiber ends.

Step 7: Insert Fiber Ropes into Lightbox

Gather the fiber ropes we made in Step 3 in an organized fashion, then feed them into the LightBox. This particular photo was taken after I'd already installed the LEDs onto the fibers. Check out this article on how to build the LightBox.

Step 8: Mount Everything Securely

Using your favorite adhesive, mount the LightBox and fiber ropes in a secure manner. This will prevent fiber breaks and loss of stars.

Enjoy Your Starscape!

Turn on the LightBox and marvel at your new stars. Unfortunately, my camera doesn't capture the brilliance and color presented by the fiber stars, but use your imagination! (or better yet, build it yourself).
