Introduction: R.R.S.S. Raspberry Pi Rave Sound System

Hi guys! We are a group of unidentified young men who are interested in technology, nature, recycling, music and several other things but none of us speak English. Some of us works, others not, some studies and there are those who do nothing but none of us is the leader. When we have some free time or we don't know what to do, we meet in a small garage and try to create or reinvent something. In addition, the 420 break is inevitable: we are GARAGE420.

This is our first instructable, it will serve to tell the story about the R.R.S.S. (Raspberry pi Rave Sound System). Let's start!

Step 1: Parts List

We need:

- old speakers

- old speakers amplifier

- wooden boards

- a piece of plexiglass

- Raspberry Pi

- PiFi Board

- USB charger with 4 outputs

- some USB-micro cable

- 1 meter USB LED strip

- 1 step-up module

- 1 universal LCD controller

- 1 10.1” screen from old tablet

- 1 HDMI cable

- some RCA cables

- electric cables

- 1 wireless keyboard

- screws, glue and nails

- old spray paint can

- something else that we do not remember

Step 2: Build the Wooden Structure

We decided to reuse some pine boards with 15 mm thickness but we obviously recommend the MDF. The structure is 1000 mm high, 450 mm wide and 300 mm deep and it is divided into two parts: one for the subwoofer and another to hold the other speakers, the amplifier, the USB charger and connections.

We used a band saw and a jig saw to obtain the wood planks we needed. These are the parts:

- 1x front

- 2x side

- 2x top

- 1x A

- 1x B

- 1x C

- 1x sub support

After we glued and nailed the parts. The box has been sanded and painted with a base coat and then be painted with spray paint, in our case multicolor.

Step 3: Mount the Speakers and the Amplifier

Ok guys now we have our painted wooden box, it's time to mount the speakers on the front and the subwoofer in the space below with the help of some screws and a screwdriver. On the back panel assemble our old amplifier, a mini subwoofer and on-off switch. This is an easy step!

Step 4: Internal Connection Cables

In our case we have an amplifier with 8 ohms acoustic impedance, 3 speakers with 8 ohm impedance acoustic, 3 speakers with 4 ohms, 1 sub with 4 ohms and another with 8 ohms.

The ampli has four channels and six sound outputs:

- first channel is directly on the board, has 1 exit and it's only for the big sub

- second channel named "CENTER" with only one output

- third channel named "SURR." with double output L-R

- fourth channel named "FRONT" with double output L-R

Fortunately we have recovered two old speakers input module and this is the scheme of the internal connections also with the USB charger.

Step 5: Plexiglass and LED

At this point we have recovered a piece of Plexiglass 450x315, we cut the space for the 10.1" screen and glued four pieces of wood.

On top of the wooden case we have obtained space to dump usb charger.

Step 6: External Connections and Test

Now we can connect the LED strip around the plexiglass and the other things like Raspberry Pi (with kodi) + PiFi Board, wireless keyboard and the universal LCD controller for our screen (which, unfortunately, there has not yet been delivered).

Ok guys for now we have concluded. We tested the speakers with a phone and the sound is really good! And we only occupied the center output! So we can expand our sound with additional speakers (2 channels left and 2 channels right). It's RAVE time!!
