    22 This Python script generates a GUI showing the latest LWATV image and runs on Linux, OS X, and the [#LWATVGUI-RaspberryPiVersion Raspberry Pi].  The GUI consists of four parts:
     20This Python script generates a GUI showing the latest LWATV image and runs on Linux, OS X, and the Raspberry Pi.  The GUI consists of four parts:
    2321  1. The latest LWATV image (or where the beams are pointed if LASI isn't running),
    2422  2. a picture of the LWA1 site with the VLA in the background,
     
    2624  4. a text description describing what sources are in the images and movies.

    28 Dependencies:
    29   * Python >= 2.6 and < 3.0
    30   * GStreamer 1.0
    31   * GStreamer "good" plugins set
    32   * GStreamer libav plugin
    33   * wxPython 2.8
    34   * PIL
    35   * gi.repository.GObject
    36   * gi.respository.GST/gi.repository.!GstVideo
     26The software is now hosted at [https://github.com/lwa-project/lwatv].

    38 === Obtaining ===
    39 You can obtain this script and the supporting files via !GitHub:
    40 {{{
    41 git clone https://github.com/lwa-project/lwatv.git
    42 }}}
    43 
    44 After checking out the software you can run it via:
    45 {{{
    46 cd lwatv
    47 ./updateMovies.py
    48 ./lwaTV3.py
    49 }}}
    50 
    51 The software also supports viewing images from the second LWA site, LWA-SV, located on the Sevilleta National Wildlife Refuge via the -2/--lwatv2 flag.  This causes the software to show images from LWA-SV as well as a picture of the LWA-SV site.  This flag is also available for the updateMovies.py script.  To run the software for LWA-SV:
    52 {{{
    53 cd lwatv
    54 ./updateMovies.py --lwatv2
    55 ./lwaTV3.py --lwatv2
    56 }}}

    63 == LWATV GUI - Raspberry Pi Version ==
    64 
    65 [[Image(LWATV-no-PASI.png)]]
    66 
    67 === Description ===
    68 The LWATV GUI can also be run on a [http://www.raspberrypi.org/ Raspberry Pi].  Running the software on a Raspberry Pi, or Pi for short, provides a low cost, low power, and easy-to-use way of displaying the GUI. 
    69 
    70 === Hardware Setup ===
    71 The hardware setup for this type of install is minimal and can be purchased for around $100.  The parts required are:
    72 
    73   * Raspberry Pi, Model B  - [http://www.adafruit.com/products/998 here is one for $40]
    74   * Case
    75     * Pibow - [http://www.adafruit.com/products/1124 here is one for $20]
    76     * Aluminum - [http://www.adafruit.com/products/1610 here is one for $50]
    77   * 5V, 1A USB power supply - [http://www.adafruit.com/products/501 here is one for $6]
    78   * 4GB SD card - [http://www.adafruit.com/products/102 here is one for $8]
    79   * microUSB cable - [http://www.adafruit.com/products/592 here is one for $4]
    80   * Display Adapter
    81     * Composite video - included on the Pi
    82     * HDMI - included on the Pi
    83     * VGA - [http://www.adafruit.com/products/592 here is an HDMI to VGA adapter for $19]
    84     * DVI-D - [http://www.newegg.com/Product/Product.aspx?Item=N82E16812816008 here is an HDMI to DVI-D cable for $10]
    85   * Monitor
    86   * Ethernet cable or !WiFi Module
    87     * Ethernet cable
    88     * !WiFi B/G/N adapter - [http://www.adafruit.com/products/814 here is one for $12]
    89 
    90 If you are worried about radio frequency interference go with the aluminum case.
    91 
    92 === Software Setup ===
    93 The software is also easy to install and based on the [http://www.raspbian.org/ Rasbian] distribution.  You can download a [http://fornax.phys.unm.edu/lwa/trac/downloads/31 pre-configured image from here] and copy it to the SD card by [http://elinux.org/RPi_Easy_SD_Card_Setup following these instructions].  After the image has been copied you can insert the card into the SD card slot on the Pi and boot it up.
    94 
    95 The Pi will be configured to automatically start the LWATV GUI software on boot and will update the cache of previous movies nightly.  The bandwidth usage for the software averages around 110MB per hour.
    96 
    97 If you are interested in building your own disk image the Pi-optimized LWATV GUI software can be checked out via:
    98 {{{
    99 git clone https://github.com/lwa-project/lwatv.git
    100 }}}
    101 
    102 ===  Additional Configuration ===
    103 The software is setup for DHCP over a wired 10/100Mbit ethernet connection and VGA output.  If your setup is the same then no additional configuration is needed.  However, it is a good idea to update both the software and the movies before use.  This can be done by logging
    104 into the Pi and running the following from a terminal:
    105 
    106 {{{
    107 cd ~/lwatv/
    108 svn update
    109 ./updateMovies.py -v
    110 sudo rpi-update
    111 sudo apt-get update
    112 sudo apt-get upgrade
    113 }}}
    114 
    115 After running these commands you should reboot the Pi.
    116 
    117 To change the video output resolution [http://elinux.org/RPiconfig see this page].  If you are using a Adafruit HDMI/VGA adapter you may also need to set "hdmi_drive=2" to get the display working.  For help configuring a !WiFi connection [http://www.howtogeek.com/167425/how-to-setup-wi-fi-on-your-raspberry-pi-via-the-command-line/ see this page].

    125 
    126 === Description ===
    127 The LWATV GUI can also be run on a [http://beagleboard.org/black BeagleBone Black].  Like the Raspberry Pi, the !BeagleBone Black or BBB provides a low cost, low power, and easy-to-use way of displaying the GUI. 
    128 
    129 === Hardware Setup ===
    130 The hardware setup for this type of install is minimal and can be purchased for around $120.  The parts required are:

    143 
    144 === Software Setup ===
    145 The software is also easy to install and based on the [http://www.angstrom-distribution.org/ Angstrom Linux] distribution.  You can download a [http://fornax.phys.unm.edu/lwa/trac/downloads/27 pre-configured image from here] and copy it to the SD card by [http://elinux.org/RPi_Easy_SD_Card_Setup following these instructions].  After the image has been copied you can insert the card into the microSD card slot on the BBB and boot it up.
    146 
    147 The BBB will be configured to automatically start the LWATV GUI software on boot and will update the cache of previous movies nightly.  The bandwidth usage for the software averages around 110MB per hour.
    148 
    149 If you are interested in building your own disk image the BBB-optimized LWATV GUI software can be checked out via:
    150 {{{
