  • eMachines EL1300G-02w – HTPC with MythTV on Linux
  • Generating power from Dry Ice [CO2 (s)] via a peltier junction
    • ]]>     I am using a EL1300G-02W computer as a HTPC using MythTv.

    It would play back 720p HD video just fine with the original processor, but couldn’t quite commercial flag new recordings in real-time while also watching a live feed. [This wasn't a big issue, as I very rarely watch new recordings live.]

    Even though it works working perfectly fine as a MythTV box with the original processor, I had been keeping an eye open on Ebay for a replacement X2 (dual core) processor for the AM2 socket.

    I was limited to CPU’s that produced 45W or less of power, which basically means the “e” line ( 4450e, 5050e, 4850e, BE-2400, 3250e). These types of processors had been selling for $50-60, but then I lucked out and found an an AMD Athlon X2 BE-2400 2.3 GHz Processor which I was able to get cheaper than average ($32 w/ shipping!).

    I decided that $32 (plus some thermal paste I already owned) was cheap enough to upgrade the CPU even though I didn’t really need the extra horsepower right now. The upgrade procedure was very painless. After removing four spring mounted screws that held the heat-sync and fan on top of the original processor, I lifted the ZIF socket lever, pulled out the old CPU, put in the new CPU, spread some new thermal paste on the heat-sync, and reversed my steps to put the fan and heat-sync back on. Total time: 5 minutes. When I powered the computer back on everything was recognized and working right off the bat, and I had plenty of extra CPU power for running simultaneous transcode and commercial flagging jobs.

    The new CPU (Athlon X2 BE-2400) had the same sizes of L1 and L2 cache as the old one, (Athlon 2650e), but the memory throughput was higher (18GB/sec vs. 12GB/sec on the L1 and 3.5GB/sec vs. 2.4GB/sec on the L2). It was also able to access the 2GB of main memory at DDR 924 (462MHz – 2625 MB/sec) instead of DDR803 (401MHz – 2065MB/sec).

    Power impact: The BE-2400 CPU takes more power (of course!) raising the idle power usage of the computer from 25 watts to 30 watts, and also significantly raises the maximum power usage (from 40 watts to 65 watts) when the CPU is running full tilt on both cores.

    I don’t mind raising the maximum ceiling 15 watts, as I rarely run the CPU at maximum, and with the faster/dual cpu’s, it should finish jobs more quickly (possibly more efficiently overall). I have decided that a continuous 5 watt penalty (when sitting idle) isn’t a bad price to pay for having (around 3X) extra horsepower around should I need it. Being able to finish ripping a CD or DVD quickly, or commercial flag two recordings at once, although not a requirement, is a nice advantage.

  • MythTV power usage
  • CPU upgrade on eMachines EL1300G-02w
    • ]]>
    I recently checked out all of the music player visualizations for the MythMusic module (part of MythTV). They vary widely in CPU usage and visual appearance. I wanted the CPU to be at least 50% free to work on transcoding or commercial flagging in the background while music was playing, so I avoided the especially fancy ones. I also found that the ones that used OpenGL used small amounts of the CPU (as they offloaded much of the processing to the GPU).

    Selected visualizations (good effects, but minimal CPU usage):

    • blank (83% idle, not much happening on-screen ) – This is the ultimate “low power” visualization, against which all others are measured. The fact that it takes my computer 17% of it’s CPU time to play ogg vorbis files should indicate why I’m somewhat CPU conscious.
    • Album Art (70% idle)
    • Squares (75% idle, simple but classy)
    • lv_gltest ( 40-60% idle, 3d histogram)
    • Gears (60% idle, simple)
    • lv_flower (50% idle, very nice!)
    • madspin (30-50% idle, fast and sparkly)

    Here is a list of visualizations that might be worth the extra CPU hit based upon their cool visual effects:

    • BumpScope (20% idle – roving spotlight on embossed scope)
    • Goom (20% idle, space tunnel effect)
    • oinksie (0% idle, kind of cool)
    • infinite (0% idle, but looks good!)
    • corrona (0% idle, falling/flowing effects)
    • jess (0%, but very very cool!)
    • jakdaw (0% idle, psychedelic flowing water effect)

    I suggest avoiding the following visualizations, as they use too much CPU for what they produce:

    • monoscope (40% idle, one red line)
    • SterioScope (30% idle, two red lines)
    • lv_scope (20% idle, white scope on black background)
    • nastyfft (20% idle, bars, almost 3d look scope) – Use lv_gltest if you like this one
    • bumpscope ( 0% idle – slightly faster movement than BumpScope, ball rolling left/right) -Use BumpScope (with capital letters) for less CPU usage, and better effects.

    The following three visualizations gave me problems:

    • analyzer (crashes computer in fullscreen!)
    • Synaesthesia (40% idle, but no visible output?)
    • Spectrum (80% idle, simple spectrum scope w/ colors, looks weird in fullscreen)

  • Waiting for a HD HomeRun before starting the MythTV backend
  • How to move a mythtv database from one machine to another
    • ]]>     If you are getting ERROR: AtomicParsley type messages in your mythexport.log file, it may be because ffmpeg isn’t exporting the files correctly. One reason for this is that config’s in mythexport that have spaces in the name cause problems. The workaround reported here is to remove the old config, rename it into something that doesn’t have a space, and then re-create the user-job using the new config. (For good measure, I made sure the user-job didn’t have spaces either.) After this, be sure to re-start the mythtv backend to make your changes take effect.

  • MythTV power conservation
  • Cutting MythTv idle power in half using a smart surge protector
    • ]]>     Switching to an eMachines EL1300G computer drastically cut the running power consumption of my MythTV setup, to an average of 45 watts when idle. (The old computer used 141 watts when idle.)

    This makes it practical to leave the computer on 24/7. I had set my old computer to shut itself down when not recording, but this required a 2 minute boot-time wait anytime we wanted to watch TV. (When it was not already awake recording a show). Even when the old computer was off, the constant current draw from the other devices (UPS/HDHomeRun/Amplifier) was 17 watts.

    The new computer takes 25 watts (when idle, up to 35 when playing video) for a total of 45 watts constant draw including the standby draw of the TV/DVD when recording shows or idle. This is more than the 17 watt draw when the old computer was off, but the added benefits is worth the extra 20 kWh a month ($2.20) in electricity.
    The two primary benefits are:

    1. Being able to turn on the TV with a remote control and go immediately.
    2. Being able to use the mythTV computer as a home file and print server, that is available 24/7.

    And, if you consider that the old computer was not shut down all the time, but was running 2-5 hours a day while recording shows and being used to watch TV (drawing 150 or more watts, compared to the 35 watts max the current computer uses), a savings of (3 * (150-35) * 30) = 10.3 kWh or more a month, my actual electricity usage is only increasing by $1.20 or less a month for the benefits of being able to access the home file/print server and TV immediately.

  • CPU upgrade on eMachines EL1300G-02w
  • DPMS monitor control via remote control on Myth TV
    • ]]>     Executive Summary: The eMachines EL1300G-02w is a good choice for a low power home theater PC (HTPC) or media computer. Pros: Small form factor, low energy use, low noise with stock fans, DVD-DL R/W +/- optical drive, lots of media card readers. Cons: 160GB stock HD will need to be swapped out for back-end use, VGA video out (only), Analog Audio out (only), minimal expansion capabilities.

    The eMachines EL1300G-02w is a $300 computer/monitor combination that is a very good choice for a entry-level home theater PC (HTPC). Some people will complain about the lack of HDMI (or DVI!) video out, but I’m happy with a plain old VGA cable driving my TV at 1360×768 (the computer will do 1600×900 with the packaged monitor, perhaps even true 1080p with a better TV!). Some will complain about the lack of a optical SPDIF port, but I’m happy with the analog audio output (I’m still using 2 channel sound with my MythTV setup!) If you want those features, spend a few hundred more on a different computer.

    This is not a monster back-end machine, as its AMD Athlon 2650e processor runs at only 1.6GHz, but it can playback 720p HD TV with only a 85% load on the CPU with XvMC enabled (leaving a whopping 10-15% left over to absorb spikes or transcode in the background). If you really want to be able to transcode and commercial flag several shows in the background while also watching HD video, you can always swap in any of AMD’s other AM2 socket “e” processors, including some of their X2 dual core processors such as the 4450e, 5050e, 4850e, up to 45W total power. My preferences for a processor upgrade would probably be the smaller 22W 3250e. It comes with 1GB of ram, which is plenty for most HTPC applications, but has a second RAM slot open for easy expansion. The hardware is fully supported by the 64 bit version of Mythbuntu 9.10 (be sure to enable the restricted NVIDIA video drivers).

    It has a single half-height PCIe expansion slot (populated from the factory with a 56K modem). The motherboard has only two SATA connections, and the power supply has only two matching SATA power cables, so although you can replace the HD, don’t expect to add a second HD unless you remove the optical drive! Speaking of HD, it comes with a 160GB Hitachi 7200RPM drive. This is plenty for a networked front end, but you probably want to swap in the biggest drive you can buy for master back-end use. Once you have the cover off, to swap the HD you will need to remove the front cover by un-clipping three black plastic tabs and rotating the front cover off the front of the computer, unlatching three pegs on the other side in the process. Then unscrew three screws holding the optical and HD bay in place. Two screws are located on the front, to either side of the optical drive, and one is located on the back screwing into the power supply.

    At a price of $300 including a 20″ wide-screen monitor, it’s a real deal. (You can also find it cheaper without the monitor.) The optical drive is top notch (dual layer DVD R/W +/- plus label-flash technology) for a HTPC, plus it has 9 USB slots (4 rear, 5 front) and a good collection of card reader slots on the front (CF/SD/xD/MemoryStick/MS-Pro). It also has front headphone/mic jacks, in addition to the (analog) surround sound jacks on the back.

    I was especially impressed with the low noise from the stock CPU and PSU fans, plus the low power consumption (25 watts idle, 35 watts playing HD video) by the 80+ bronze EnergyStar rated power supply and stock Athlon 2650e CPU. (Measured after swapping in a 1.5TB Seagate Barracuda 7200 HD.)

  • Mythtv gotchas when upgrading from Ubuntu 7.04 (Feisty) to 7.10 (Gutsy)
  • DPMS monitor control via remote control on Myth TV
    • ]]>     To set up lircd with the hdhomerun to see a tivo series 2 remote control, you should first program the HDHomeRun to send UDP packets to your linux computer with a command such as the following:

    hdhomerun_config <device id> set /ir/target "<lircd ip addr>:<port> store"

    You can test that this is working by running:

    irrecord -H udp -d 5000 "testing"

    If you get dots when you press your remote control buttons, the HDHomeRun is sending IR information to your linux box. (remember to unblock UDP port 5000 for incoming transmissions if you are running a firewall!)

    Once that is working, just set up your /etc/lirc hardware.conf and lircd.conf files to support the Tivo series 2 remote.

    Here are the entires from my files, starting with hardware.conf:

    # /etc/lirc/hardware.conf
    #
    # Arguments which will be used when launching lircd
    REMOTE_LIRCD_ARGS="-H udp -d 5000"

    #Don't start lircmd even if there seems to be a good config file
    #START_LIRCMD=false
    START_LIRCD="true"

    #Try to load appropriate kernel modules
    LOAD_MODULES=true

    # Run "lircd --driver=help" for a list of supported drivers.
    REMOTE_DRIVER=""

    # If DEVICE is set to /dev/lirc and devfs is in use /dev/lirc/0 will be
    # automatically used instead
    REMOTE_DEVICE=""
    REMOTE_MODULES=""

    # Default configuration files for your hardware if any
    REMOTE_LIRCD_CONF=""
    LIRCMD_CONF=""
    REMOTE="None"
    TRANSMITTER="None"
    TRANSMITTER_MODULES=""
    TRANSMITTER_DRIVER=""

    TRANSMITTER_LIRCD_ARGS=""
    START_LIRCMD=""
    FORCE_NONINTERACTIVE_RECONFIGURATION="true"
    REMOTE_SOCKET=""
    TRANSMITTER_SOCKET=""

    And then the lircd.conf file:

    # brand: TIVO

    # model no. of remote control: This is for the Tivo with the DVR 1/2 switch

    # devices being controlled by this remote: Tivo Series 2 (maybe more)

    # This conf file allows the support of Tivo Series 2 remote. In particular,

    # it allows for the unique key definitions for each of the 39 keys when DVR

    # Switch is in positon 1 or 2. This essentially doubles the number of keys

    # one can use just by toggling between DVR 1 and 2. For example, an lircrc

    # file can be programmed to execute one thing when the play button is pressed

    # when in DVR 1 mode and execute a different function when the same key is

    # pressed when in DVR 2 mode.

    #

    # In order to use this, one must first set the remote. Move the DVR SWITCH

    # to 1. Next, Press and hold the PAUSE and TiVo buttons simultaneously

    # until the red light at the end of the remote control comes on, remains

    # steady, and then stays on when you release the buttons. Now press 1.

    # Do the same when switched to DVR 2 (assigning it to a number 2).

    #

    # Now you can use the codes below. All the functions which begin with a 1

    # are associated with the DVR1 switch and those prefixed with 2 are assoc

    # with DVR 2 switch. Since the remote allows it to be programmed with any

    ]]>     Backup the database on your source machine. Newer versions of mythtv do this for you automatically. Check out the mythconverg_backup.pl script if you have to do it manually.

    Delete any existing database on your destination machine:

    $ mysql -u root
    mysql> DROP DATABASE IF EXISTS mythconverg;
    mysql> quit

    Re-create the empty database on your destination machine:

    $ mysql -u root < mc.sql
     (You may need to use the -p option and enter your root password)

    You may also have to set up the mythtv user with the correct password:

    $ mysql -u root < mc.sql
    UPDATE user SET Password=PASSWORD('YOURPASSWORDHERE') WHERE user='mythtv';
    FLUSH PRIVILEGES;

    After this, run the mythconverg_restore.pl script:

    mythconverg_restore.pl --filename mythconverg-1214-20091010150513.sql.gz

    You may have to specify hostname, database name and enter the password if you don’t have a mysql.txt file set up in my .mythtv directory. You may also have to specify the fully qualified path to the file if it’s not located in your default backup directory.

  • Waiting for a HD HomeRun before starting the MythTV backend
  • Discovery Error 4001 : Silicon Dust HDHomeRun error
    • ]]>     MythBuntu (and Ubuntu I assume) don’t support the AutoIP standard.
    (Auto IP is basically a way for devices to form ad-hoc networks…if you don’t have a static IP, and are not assigned a dynamic IP via a dhcp server, you try out a random address in the 169.254.x.x network (255.255.0.0 netmask) and as long as ARP doesn’t report a conflict, you now have your IP!)

    Windows, and the HDHomeRun devices support this, but MythBuntu 9.10 does not. So, I’m back to using firestarter to easily configure my MythBuntu box to assign the HDHomeRun an IP address via DHCP.

  • MythBuntu doesn’t support AutoIP
  • Silicon Dust replacing HD Homerun power adaptors
    • ]]>     SiliconDust HDHomeRun Discovery error 4001I was in the process of changing out my MythTV backend machine, and when configuring the new machine, I took a look on SiliconDust’s website for a firmware update for my HDHomeRun (HDTV Network tuner box). I hadn’t updated it since late 2008, and sure enough, they were five or six firmware versions farther along. (Up to 20091024 to be specific.) So I upgraded the box using the newest version of the hdhomerun command line utility under linux. Everything went fine until the HDHomeRun rebooted. After that point, the utility said that an error occurred discovering the HDHomeRun! I tried booting into windows to try out the windows software, but it also could not discover the device, and gave me this ominous message:

    Discovery Error 4001: Please email support@silicondust.com

    Apparently this is a known issue, as the troubleshooting document from SiliconDust says: “The HDHomeRun requires an additional configuration update. Email support@silicondust.com, or file a trouble ticket; be sure to include the device ID listed on the bottom of the HDHomeRun and “Discovery Error 4001” in the message.”).

    From reading other blog posts, it appears that the fix is for them to send you an executable file. You run the file, and it fixes your HDHomeRun over the network. I can accept this, but I’m not happy with having a firmware update freeze my HDHomeRun (on a Sunday, with the earliest support response 12 hours away). As a last ditch effort, I plugged the HDHomeRun back into my current MythTV computer, and was surprised the find that it still worked! Apparently, as long as MythTV is already configured, things are still working, even though I can’t discover the device!

    When looking into this, I found what I think is the problem. The firmware update has blown away the last 24 bits of the device’s MAC address. When it asks for a DHCP address, you can see that the last three bytes are all zeros: (after the 00:18:dd)

    Dec 20 16:50:31 elvira dhcpd: DHCPOFFER on 192.169.1.2 to 00:18:dd:00:00:00 (HDHR-FFFFFFFF) via eth0
    Dec 20 16:50:32 elvira dhcpd: DHCPREQUEST for 192.169.1.2 (192.169.1.1) from 00:18:dd:00:00:00 (HDHR-FFFFFFFF) via eth0
    Dec 20 16:50:32 elvira dhcpd: DHCPACK on 192.169.1.2 to 00:18:dd:00:00:00 (HDHR-FFFFFFFF) via eth0

    So my suspicion is that the executable that SiliconDust will (hopefully) be sending me on Monday re-programs the devices MAC address for you. (and possibly fixes other configuration bits that also got blown away?) In any case, I wish they had a universal fixer program that I could download from their website now, when I had the problem, instead of having them custom make me one and then send it to me. (I wonder why they don’t trust me to enter my device ID myself?)

    Update: 24 hours later they sent me a windows executable (which came with a cygwin dll file) that re-set and fixed my HDHomeRun.
