To start openbox and the jivelite client, you will need to prepare an .xinitrc file that establishes your environment. An example of what I used can be found at my github page. You will need to make sure that the last line is correct for your path to the jivelite binary file.

$ chmod +x .xinitrc

Modify Openbox Configuration

Openbox relies upon a simple XML configuration file. For our touchscreen we don't want to show any of the standard window decorations that a normal window manager shows so we need to make a slight edit to this file.

First create a directory in the squeezeuser's home director call ".config". Please NOTE the "." before the word "config" and make sure it is there. This will make this directory a hidden directory and it is where Openbox will look for the configuration file. Next, make a subdirectory within the ".config" directory entitled "openbox".

$ mkdir .config 
$ mkdir .config/openbox

Next, copy the standard Openbox configuration file into this directory.

$ cp /etc/xdg/openbox/rc.xml ~/.config/openbox/

Finally edit the rc.xml file to add the following lines near the bottom:

$ nano ~/.config/openbox/rc.xml

<!-- match all windows and remove their decorations -->
	<application class="*">
	  <decor>no</decor>
	</application>

This should be inserted just before the end of the document right after the lines that read:

# end of the example<br>-->

And right before the very end of the document, which ends with:

</applications>

</openbox config>

so the full end of the document should be:

<br># end of the example<br>--><br>
<!-- match all windows and remove their decorations --><br>     <application class="*"><br>        <decor>no</decor><br>      </application><br></applications><br></openbox config><br>

3 More Images

1. Locate and drill holes for the Mimo screen
2. Pull the USB cable through the wall
3. Plug the USB cable into the Mimo screen
4. Mount the Mimo screen on the wall using the appropriately sized screws and washers
5. Position the circuit breaker cabinet near the opening
6. Pull the USB cable into the circuit breaker cabinet
7. Pull the speaker cables into the circuit breaker cabinet
8. Pull the Ethernet cable into the circuit breaker cabinet
9. Pull the line-voltage power cable into the circuit breaker cabinet and attach per code (I used Romex cable and standard screw-down compression attachments).
10. Insert the circuit breaker cabinet in the wall and attach to stud.

Run the appropriate cables for your setup. Proper cable management is important as you have limited space, and while the Raspberry Pi doesn't put out much heat, together with the amp you want to make sure you have reasonable airflow.

During the construction of the room in which the player was being installed, I had run speakerwire and an Ethernet cable to the location where the circuit breaker cabinet was located. After the room was finished, I cut holes in the ceiling to insert the in-ceiling speakers. I used these JBL speakers that were reasonably priced and good quality (don't pay the price listed on the JBL site, they are much cheaper elsewhere).

Test you speaker connections before you insert the speakers in the ceiling. They will come back out if you work at it, but it can be difficult.

Once you have everything working, close up the circuit breaker cabinet. In my circuit breaker cabinet, the front plate contains small breakouts for each circuit breaker. If you need to get access to the interior of the cabinet to adjust the volume or to otherwise work with the other parts, you would not be able to reach through any of the holes. Instead, I cut out the portion of the plate (behind the door) that holds the circuit breakers. This gives a reasonable sized opening so you can easily access the interior of the circuit breaker cabinet. Make sure you clean up your cuts and debur the opening.

I hope you enjoy this project.
