My original LED light cube got allot of reactions. Some of them where about making the LED's react to music. This did sound very interesting and I found some instructables on here.
Unfortunately I found it very hard to understand those instructables. In my opinion they weren't explained well enough and even some circuits weren't correct.
That's why I though I build one and make an instructable of it. I tried to make this instructable so easy, that everyone with or without any experience can make one!
If you make one, don't forget to share your end result photos and movies with us.
Below you'll see the end result of my Music LED Light Box.
The movie is shot with my Canon Digital Camera, in the dark. My camera can't handle the fast switching between light and dark very well. In reality the effect is even nicer then on the video.
Before people go asking who's music or what songs these are in this video, these beats are made by my brother. :)

In this instructable I'll explain how I made it, a very simple way.
Materials
- 12v Adapter (a battery can be used as well)
- 3.5 jack headphone cable.
- tip31 transistor (this is the key to the whole project) - $0.50
- 5mm LED's (the color or amount is totally up to you, 1 LED per 3v. I used 12v, so 4 LEDs) - $0.28
- A4 acrylic sheet - 3mm thick (also known as 'plexiglass') - $2.00
- Fine sandpaper (I used 400) - $1.00
- Electrical Wire
If you see a price above, that means I bought it. The rest I just ripped of some old junk. The 12v Adapter was from an old wireless headphone and the 3.5 jack plug is from another old headphone.
Tools
- Jigsaw (also a Jeweler Saw can be used. But that's really hard to get straight lines)
- Glue Gun (hot glue, other glue to glue acrylic is possible)
- Drilling tool
- Solder tool (optional)
- Pen
Ones you've got this stuff you're ready to begin!

and i got an NPN Transistor instead of TIP31 because! this transistor works with 2 AA Batteries! so its 3V and i got the same Results! less Power MORE MAH!
-Upgraded it with 2 Speakers! so its now a Acrylic Plexiglass box with Speakers and Leds Syncing on the Rythm of the music!
Motadacruz, just tell me if u want to see my video and what do you think about it.
Peace.

Lets say I have my stereo to Volume 10, and the lights are on constantly. But if I have it on volume 7 it works perfectly.
Now would this be the case for this setup or would I have to add or do something totally different?
What I am looking at doing is instead of an aux in cable, I wire it directly to my Subwoofers speaker cable inputs (coming from a car amp) which would in turn receive the signal from my amp. However I want it to always be at the optimum input level. Only thing I can think of (and not in electronic terms) is a limiter of some sort.
So regardless of how high the input is, I can tune it to a point with a dial that it will always work at that level (unless it is a very low volume which is fine anyway).
i wanted to make the pcb !
Having one TIP31c
I followed this picture but instead of using a battery I just use my arduino Diecimila powered on the USB and one led without resistor, but when I put the right wire of the jack and the ground of the right wire on the TIP31C sometimes it just turn on and keep the light or nothing appear and then when I start the music nothing is there...
please some ideas????
i have build this system and it works perfectly when i plug it in on my radio
but if i plug it in on my iPod or amplifier it doesn't work. i used a multiplier and saw that my radio gave much more power. but i want i also on my iPod or amplifier.. how can i fix this?? (i'm sorry for my bad English, i'm dutch)
