In this instructible I will show you how to make a "crystal" pendant that glows three different colors.
This is a great idea for a costume.
If you have any ideas or suggestions im happy to hear them.

Step 1: Step 1: the Supplies

What you will need for this project is:

1"x1"x4" piece of plexiglass
about 25-50' of wire (I used phone wire)
an LED from a cd player from a PC (must have three prongs on it)
an Altoids tin
two push button switches
three 'AA' batteries
piece of aluminum or any other metal

The tools needed:

a drill
a sander
a saw
a soldering iron
wire strippers
and always wear safety glasses when cutting anything!!

Step 2: The Wiring

This is a diagram for the wiring inside the Altoids tin.

To reduce the clutter of wire I braided it so it would be easier to work with and cover.
Heres a link to show how to braid.

Step 3: The "Crystal"

The crystal is made by cutting a piece of 1" plexiglass into a piece that measures 1" wide by 1" tall by 4" long.

Then take a sander (I used a belt sander) and grind the edges down to make it look like this:

Then drill a hole about an inch into the top in the center for the LED.
