Got My Raspberry Pi Up and Running

I say that as if it was hard.  Actually, it was pretty dang easy to get the OS (a Linux variant) loaded on the memory card.  Seems to work fine -- you can see I have Coyote Blog up in the browser.  I am playing with it because I am looking for something to control signaling and other systems on a model railroad.  I am more likely to use some kind of Arduino setup, but I wanted to play around with Python on Raspberry Pi as well.

Here is the card.  The top wire is a micro-USB 5v power connector.  Clockwise from that is a 32GB SD card (for memory), a bunch of empty programmable pins for I/O on the upper right of the board, the composite video connector and audio headphone out, two USB ports with my wireless keyboard connector, the network cable, and on the left the HDMI cable for video out  (don't know yet if it has audio out over HDMI).  As in the Arduino community, there are already daughter boards for the pin-outs with breadboards, motor controllers, and other gizmos.

Projector Reviews

I know that those of us who use projection TV at home are a tiny niche (tiny but happy!).  For those who are interested, this guy puts out the best projector reviews I have seen.  I am a big fan of the Epson line and yet again, the Epson (this time the 5010) wins in the mid-price range.  I have the previous version, and it is the ideal  projector for someone like me stuck with a bad room, meaning a non-dedicated home theater where in the daytime there is a lot of ambient light.  Very bright for daytime sports, great blacks and color in movie mode when the room is dark.

I have not tried the new wireless HDMI built into the "e" models of these new Epsons, but it should be a huge boon for projector fans.  Running signal wire to ceiling mounted projectors has always been a pain, especially as the standard has shifted about three times since I first wired my house  (composite to S-Video to component to HDMI).  But HDMI is particularly hard, since the HDMI standard was never really spec'd for long runs of wire.  It is very dicey getting a reliable high-frequency signal (ie that needed for 1080p 3D) through HDMI cables that may be more than 25 feet long.

Some Blu-Ray Advice

I am a bleeding edge guy when it comes to home theater, so I have had a Blu-Ray high-def disk player for over a year.  I am currently looking for a second player to replace the first, and I thought I might share a couple of thoughts.

The press has declared the high-def DVD format war over, with Toshiba pulling the plug on the HD-DVD format.  This makes it much easier to figure out what software to buy (though it is still really expensive -- some Blu-Ray disks are going for $40!)

However, the hardware issue is still a minefield.  This is related to how the Blu-ray standard is being run, which presents problems and opportunities.  Unlike your CD or DVD player, the Blu-ray standard continues to evolve.  A lot.  It is much more like a computer standard, and I suspect in fact that the computer guys (or at least the game console guys) are running the show here.  This means that new features continue to evolve and be added.  And these are not just add-on features, like additional hardware inputs, but software features that create compatibility issues between versions.   As a result, there are already at least 3 generations of players out there.  The original profile 1.0, and then profile 1.1, and now profile 2.0.  And even within these profiles, individual players may vary in their conformance to them.   Sometimes you can do a firmware upgrade to a newer spec, and sometimes you can't, but such upgrades are not a piece of cake, and involve burning a DVD from the Internet and running certain codes from the Blu-ray remote to make the firmware upload.

The net result is that the features on a certain disk may not work on your player, or the disk may not work in your player at all (Newer movies like Pirates of the Carib. III have multimedia title pages that won't load on my player, and when the title page won't load, there was no way to play the movie.)  My advice is if you have waited this long, hold out until this summer for the newer profile 2.0 machines.  Also, you should confirm the player supports HDMI 1.3, so it can take advantage of the wider color gamut of newer TV's.  Players of this spec will start showing up in the next months -- the Sony BDP-S350 will likely be a good choice available this summer.

By the way, good luck finding anything on the box or in a Best Buy store that says what profile the player conforms to.  Hardware makers have created a really compatibility mess with Blu-ray (its seems to be a very poorly run standard) but they want to hide this fact from consumers because the are only just now recovering from the format war with HD-DVD and don't want consumers to have another reason to wait to purchase.  So there is not way they are going to put the profile number on the box, I guess, so you need to do your research.

As a final thought, and maybe I am just old and out of step here, but I really find the insistence on multimedia content and bitchin-cool menu screens on Blu-ray disks to be tiresome.  I just want to watch the movie in beautiful high-resolution, and having my software not work right because the menu doesn't work is just stupid.  Further, the addition of all these features has caused most blu-ray players to have a boot up cycle longer than Windows.  It can take 45 seconds for a blu-ray player to boot up, and a similar amount of time to get the software to start playing.  Add in the time to plow through stupid menu screens, and it can take several minutes to get a movie started.

Tonight I watched Cloverfield on blu-ray and it was awesome.  I was surprised the reviews on Amazon were so bad for Cloverfield, because I really liked it.  Yea, its different, but unlike movies like Bourne Ultimatum, there is actually a explanable reason for the jerky (and sometimes nauseating, I will admit) camera work. I did not pay much attention to it when it came out in theaters -- is this one of those geek litmus-test videos that only a few of us hard-core nerds like (a la Serenity?)

Cheap Cables? Well Mostly

This post advocates always buying the cheap home theater cables.  I agree up to a point.  I have never been able to hear the difference in really, really expensive cables, say for 3 foot interconnects.

But there is an exception to this, and it is interesting the author Glen is quoting actually uses this example -- long runs of video cable, particularly HDMI.  If your TV sits on top of your video source, and the video run is 6 feet or less, then the average person with the average equipment will not notice the difference in video cables.  But should your cable run extend to, say, 25 feet or more, then you are going to have problems.  Video is both very high bandwidth and very susceptible to noise.  HDMI and other digital cables are no exception  -- the only thing that changes are the symptoms. 

In an analog cable, you will start getting a lot of video noise with longer cable runs.  Computer VGA cables were notorious for this -- if you went more than 6 feet, your picture could be a real mess.  SVGA S-video also had such problems.  Now, with digital cable, the picture does not gain noise but at some point the signal is lost altogether and the picture drops out completely -- think of a youtube video streaming over a bad wireless connection.   I will about gaurantee this will happen with 25 feet of JC Penny HDMI cable.
