Building a Home Theater PC (HTPC)

Larry Templeton 

(REVISED Jan 2010)

At the April 2009 SPAUG meeting, member Larry Templeton described how he built his own Home Theater PC. 

Bill Young really laid the groundwork for tonight's talk a couple of month's ago when he made a presentation to the group about how to build a standard desktop for the PC so I'm not going to go into the nuts and bolts of it, but I do want to talk how they work, how they fit into a home entertainment system and the parts that you might want to procure if you are going to build one.

What can an HTPC provide? 
  • Record /store/ replay off-air/cable TV shows, DVDs, CDs, ipod, MP3s, etc. 
  • From the internet, download /store /play YouTube, Hulu, Netflix, TV shows, movies  (amazing amount of content now available)
  • Edit video, burn DVDs, CDs, load iPod, etc.
  • Any other PC function such as surf the  internet, play games, etc.
  • Watch off-air, cable & satellite TV
  • Get rid of all your old CDs, DVDs, etc.

Ubuntu, Windows and Virtual Computers

At the July 2009 General Meeting Hank Skawinski promoted Ubuntu as a better operating system (OS) than Windows. Hank showed us his new netbook computer that dual-boots Windows XP and Ubuntu. He booted into Ubuntu and showed us many of its features. Hank noted that Ubuntu cannot run some critical Windows programs, such as TurboTax, Quicken, QuickBooks, and Photoshop. This keeps many users from considering Ubuntu.

Using a virtual computer, I am running Windows XP and Windows programs, including the above programs, in Ubuntu. As a timely follow up to Hank's talk, Hank and Jim Dinkey asked me to describe to the club members how I do this. 

Wildlife Photography at Your Local Zoo

Budget Safari title photo of a snow leopardMost of us love looking at photos of wild animals, but few of us can afford the expense of a safari to the places where they live in order to take the pictures ourselves. But there is another option available to us. Our local zoo. On June 19, 2009 Bogen Imaging presented a webinar with Julie Larsen Maher, the head photographer for the Wildlife Conservation Society which oversees the major zoos in New York City. This webinar, which might be titled "Safari on a Budget" was replayed at the July DISIG meeting. For those who were unable to see it, I have compiled a list of the many tips and tricks which Julie described along with a few of her superb photos. If you want to see the entire one hour webinar, you can visit the Bogen Café site.

How to Build Your Own Computer

 
In February 2009 SPAUG member Bill Young described how he designed and built a "general purpose" desktop computer, including:
  • Choosing whether to buy or build your new computer
  • The ease of building your own computer
  • Deciding on the objectives for your computer
  • Selection of hardware components to meet your objectives
  • Choosing your operating system

The advantages of building your own system include custom components wth better reliability and longer life, lower power consumption and cooler, quieter operation compared to purchased computers.

Removing Pops and Clicks with Audacity

Many people have collections of vinyl recordings which they would like to transfer to digital format. At the March 2, 2009 meeting of the Multimedia SIG Bob White presented suggestions for how to enhance the quality of these transfers by removing extraneous noise ("pops" and "clicks") from these recordings.

Open Source Software - Is There Really a Free Lunch?

From Linux, Open Office, Firefox and GIMP to a growing list of other applications Open Source has become a popular alternative to costly commercial software. Open source software is developed by a community of programmers with peer review and transparency of process. The promise of open source is better quality, higher reliability, more flexibility, lower cost, and an end to predatory vendor lock-in. (Presented by Maurice Green at the August 2008 General meeting. Additional material and links have been added.)

Use of Kodak Plug-in Filters for Photoshop

Plug-ins are small independent programs which perform functions within the photo editing program (e.g. Photoshop). Hundreds of plug-ins are available, some for free, Many plug-ins provide more levels of adjustment or more sophisticated ways of performing normal image correcting functions such as sharpening or applying smoothing blurs. In the examples shown the original unedited image is shown followed by the result using different techniques for achieving the desired correction. Each image represents a single technique; effects are not applied sequentially. This lecture/demonstration was presented at the October 2005 DISIG meeting.

KAP: Kite Aerial Photography

Bruce Owen, PhD

Pillistay site thumbnailWhile poring over aerial photos of a coastal valley in southern Peru, I noticed the fuzzy images of several large, complex, grid-planned sites in a virtually unknown region. Visiting the sites, it was easy to see that the architecture was complicated, but difficult to understand the layout from the ground. Some aspects of the plan and walls suggested that the sites might have been built by the Wari, a pre-Inka expansive state dating to around AD 500 to 1000, but a millennium or so of debris flows from the valley walls and a layer of volcanic ash from AD 1600 cover the surface, hiding the artifacts that would normally help to date the sites. Understanding the architecture will be key to guiding excavations in three of these sites this summer, and to accurately mapping them using a sophisticated GPS and laser rangefinder system.
