How to make a moody crystal light for under $10!
It is time to make good use of the Selenite crystal that has been sitting in my room for ages. I brought the crystal from a collection shop while ago on holiday in Devon for $2. You don't have to use the selenite crystal for this project, you can use any kind of crystal that is transparent or cloudy.
BTW, I am British, I have to use the American currency symbol because instructable dose not like the British currency symbol.

Nothing really expensive, other than the RGB LED's and the crystal, they can be quite expensive in some place.
- Double AA battery holder
- Two AA batteries
- A switch
- A small piece of veroboard
- Some wires
- Transparent or cloudy crystal
- A project box (I ran out of them, so I have to use a container)
- RGB LED's (see next step)

You should mention that these are autochange RGB. most RGB (such as the ones you get off digikey) do not have the built in circuit that causes the color change. RGB LED is a LED w a red, green and blue LED glued under a single lense (speaking most simply) and one lead in common. Changing the voltage to the other leads is what gives the different colors

Otherwise, I like the application. :-) (if I could find my crystal I have that glows under UV lights I could add a few UV LEDs to make it really spooky looking in the dark ;-)
