Constellation Projector (From a Coffee Cup)

In this instructable, you will learn how to build a simple projector (in our case, for constellations).

Here is a little background on constellations:

Constellations are "pictures" or arrangements of stars in the night sky. Similar to connecting the dots, you can "draw" images. These images made of stars are called constellations, and they often hold significant importance in our daily lives. For example, one of the stars in the constellation of Ursa Minor (the "little dipper") is the north star, and has been used in navigating on the sea for centuries.

You can skip the electrical part of this instructable by using a flashlight to illuminate the projector and provide the light.

P.S. We apologize beforehand that the cup we used was not a coffee cup. I did not have access to a cup when I made this instructable.

But now to start the instructable...

*This project was done with the help of legoguru4u (camera and knife work).
