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.

Step 4: The Finished Pics

This is the final look of the "crystal" pendant.

I'ts a very good-looking idea but, aside from the color changing diode, the altoids/AA PSU is waaaaaaay to big. With button-batteries you should fit everything into the cover.

I've heard of smaller versions of this being made by actually grinding down the sides of the LED instead of a cover for it. but you have to be careful not to grind down too much and damage the parts that matter.

i've seen that but there is no grinding of the LED which makes it last longer

Hi Great Idea look really cool. Have you ever thought of using a led that automatically changes color like this one.
