This instructable shows you how you can make a fiber optic lamp flash it's lights to whatever music you plug in. If you have an Android device you can also control it with a wiimote. I was inspired by a product found here. Continue to the next step for a list of parts and have fun!

Step 2: Assembly (Lamp)

First unscrew the battery holder and have a look inside. It SHOULD accept 4.5 volts (3 AA batteries). You need to figure out where to solder on your positive and negative wires and then close the base back up so that the wires protrude from it.

Step 3: Assembly (Headphones)

Preparing the headphones can be a little tricky. You need to find a pair of headphones that you don't mind destroying first. After that cut off the ear buds and remove about 1 inch of the plastic cover from the ends. You should have two wires protruding from each side. On one wire, you will have a copper-colored wire and a blue/green wire. On the other you will have a copper-colored wire and a red wire. Twist the copper wires together and then twist the red wire with the blue/green one. Burn off the ends to reveal the inner wire and solder the twisted groups together. Refer to the picture.

Step 4: Assembly (Circuit)

After you finish creating the circuit either mount it on a base with hot glue or solder it onto a permanent circuit board. Then cover the wires (especially the fragile headphone wires) in hot glue to make it permanent (ONLY DO THIS AFTER YOU HAVE TESTED TO MAKE SURE IT WORKS). Read the annotations for explanations.

Step 5: Finish Assembly

Now you need to file down notches in the base for the wires to extend from.
