This project will light up as many LEDs as you want in sync with the bass of every song. This is an Extremly easy project to make, even without electrical experience

Step 1: Materials

You will need a subwoofer that you can take apart, some wire, as many LEDs as you wish to use, as many clear pen tubes as LEDs, water, and whatever material you want to make a stand out of

Step 2: Tools

Tools you will need are: wire strippers, wire cutters, needle nose pliers, soldering iron

Step 3: Subwoofer

Take the subwoofer apart (or on some just unscrew the subwoofer speaker). The only thing you need to focus on is the red and black wire attached to the speaker. Strip half an inch off of the end of 2 of your wires. You should mark which wire is negative(black) with a felt pen along the length of the wire. Now solder the unmarked wire onto the positive (red) wire. Next, solder the marked wire onto the negative (black) wire. Before you put the case back together, use your wire cutters to make a small nick in the case so that you can fit your wires through so that the case doesn't damage the wires Put the case together.

Step 4: Holder

You can use anything you want to build the holder. I used Lego because its cheap and super easy to work with. The holder should be able to fit your clear pen in it lengthwise. And hold the pen straight as there is going to be water in it. Once your enclosure is complete, fill your pen tubes with water and place them in the holder (Note: I taped my pens to make the LEDs brighter. In some cases it may not be neccassary, it depends on the LEDs used)

Step 5: LEDs and Wiring

The wiring is really simple. I have included a diagram but all you need to do is connect all the positive ends of the LEDs together and all the negative ends of the LEDs together. The negative side of the LED will be flattened or have a shorter leg, depends on the LED. Connect all the needed LEDs and wires together with solder and a soldering iron. Next connected the marked wire from the subwoofer to the negative of your LEDs. Connect the unmarked wire to the positive of your LEDs. If your structure has a lid, put the lid on, as you are finished!!

Step 6: Turn It Up!!

Just connect your subwoofer and speakers and watch the light show!! Thank you for having a look at my first instructable. :)
Thats not the right way mate. Directly wiring LEDs to woofer out may seem pretty at first , but may burn the LEDs or The amp or The whole house someday. the right way is to use TIP31 Transistor.
I dont have any extra money to spend as i am a student so thats why i did it that way but thank you very much for the input
no video no party :(
