About: Hi, my name is Jan and I am a maker, I love building and creating things and I am also quite good at repairing stuff. Since I can think I've always loved creating new things and thats what i keep on doing ti...

Hello community,
in this instructable I want to show you a great project I built. A selfmade, glowing Ghettoblaster made out of lying around materials. So if you are interested-> keep on reading:).


Step 1:

I started with this old box, which i builded 2 years ago. It's a simple wood construction with two 180W 3-way-speakers. I wanted to make something great out of it so I started collecting ideas untill I came up with the idea of building a mobile speaker.

Step 2:

I found an old amplifier, which i once bought from ebay for 10 euros. I tested it out and it sounded great :). Then used an old pvc pipe and made two bass tubes out of it to hopefully get an even better sound result. After this I cutted out two wooden pieces for the sides of the box and painted them gray.

Step 3: Making It Glow

To make the Ghettoblaste glow, I used RGB-LED,s. I installed them on the speakers and in the bass tubes. I got a really cool light effect from the tubes which you can see in the last step's photos.

Step 4: The Electronics

I kept the controls simple. I decided to use one main switch (the red one) to turn the amplifier on and 3 white switches to control the 3 LED colors. Unfortunately I forgot to add a 12V regulator to adjust the voltage for the LED's, the fully charged battery brings it up to 14,5V:D. I also added two battery connectors and a charging port on the outside. The whole wiring was quite tricky but in the end I got everything soldered and insulated:). 

Step 5: Assembling the Box

I cutted a square piece out of a perforated metal plate as a cover for the battery hole. With some hot glue I fixed the bass tubes and the electronic components . After this I could finally attach the sides to the box with nails and some wood glue.

Step 6:

To make the blaster easy to take along I made a handle out of an old lashing strap and two small pieces of the metal sheet that I also used to cover the battery hole. To make it I cutted the strap to the right lengh, pleated the ends around the metal pieces and sewed it together. 

Step 7: Painting It

I painted the rest of the assembled box in gray and silver. 

Step 8: Connecting the Battery

A 12V lead-gel battery powers the device. With some velcro and rests of the lashing strap the battery is held in place but still easy to remove. Now the ghettoblaster was ready to use. With a selfmade charging cable I'm able to charge the battery through the charging port without taking it out.

Step 9: The Result

So this is how the finished project looks. I loved it but I wanted to sell it to have money for another project. It took two days until somebody bought it for 120 Euros. That was much faster than I expected it to be sold so I haven't had any time to have fun with this Ghettoblaster :/ //time will heal any wound and the money might also help to survive the pain ;D. However, I really hope you like it and if you do please vote for it :). Thank you for reading:).

    Does the beat of the music change the color of the LED's? I've heard if you tap into the speaker wire you can possibly do that, but don't quote me on that!

    Nope, the music doesn't affect the LED's. The idea is nice and I actually thought about using a music controller to get this effect but then I decided to keep it simple so I used the 3 switches to control the 3 LED colours. Now I can let them light up in 7 different colours. My friends and I are already working on a new project. In this project we used a music controller so that the LED's flash or fade according to the beat. I hope I could answer your question :).

    all you would need is a simple TIP31 Transistor, which only costs around $2 bucks, to have the LED's flash to the beat. It's not as amazing as a full on controller, but it does the job pretty damn well and would have added that extra little something-something to your already sweet Instructable.
