Building DVR and HTPC

  • Case
    Your case is important because it is going to be sitting in your living room alongside your television, DVD player, stereo and so on. You don’t want some beige office PC cluttering up your home theater. Here you can either splurge on a custom, HTPC case or you can paint and customize your own. I went with contact paper and acrylic paint as a cheap solution to decorating a beige case.
  • Video Card
    Incredibly, your video card is a place you can save some money on your homemade Tivo. Unless you plan on playing some serious high-end computer games, all you need is an appropriate video out (s-video, DVI, or HDMI depending on your needs).
  • Tuner Card
    Make sure you don’t go cheap here. Go with a Hauppauge brand tuner card. At least the PVR-150. These are quality cards that take a load off your main processor.
  • Sound Card
    You can get a card with 5.1 surround sound for about $50 (maybe cheaper on eBay). If you want to hook up with your existing stereo system, you’ll want to spend a little more on a card with an S/PDIF out.
  • Memory

Basics of VoIP

VoIP stands for Voice over Internet Protocol but is more commonly know as Digital Phone, Broadband Phone, or even internet Phone service. Simply put, it refers to using your internet connection to talk to people. The people you talk to can be across the world or even just down the block.

Although there are free programs to let your computer act like a telephone, it is more common for people to purchase specially made devices that are separate from their computers but still use their internet connections. These devises then also plug into your homes telephone wiring system. This has the advantage of allowing people to use the phone equipment they already own.

To make a call, just pick it up, dial a number and talk just like you would with a traditional phone service. It does not matter if the person receiving the call has VoIP or not, because that is taken care of by your VoIP service provider.

Compared to traditional phone services, VoIP is often more cost effective. And because it is not yet regulated like the traditional phone industry there are no unexplained taxes or mysterious service charges. Because all calls

Protyping Made Easy

Prototypes are an important step in the manufacturing process. It is in this process that we will encounter computer numerical control or CNC prototyping. In CNC prototyping, a computer controller basically translates the design data and produces a 3D output of that data through a mechanical device.

This whole process has revolutionized the manufacturing process because previously, prototypes were difficult to produce because it consumed a lot of time, effort and cost to make. Now with CNC prototyping, complex 3D virtual designs by design engineers are easily translated actual 3D models with straight and curved lines easily replicated automatically. With CNC prototyping machines, producing prototypes are fast, easy and cost effective.

Now that CNC prototyping processes are available for most prototyping problems, the manufacturing process is greatly sped up. The savings in time and effort allow greater productivity by allowing design engineers to work on more with less time needed. This means a greater and faster turn over within a shorter amount of time. This of course then directly translates into the bottom line and profits for the business.

Sometimes, there is need for more than one CNC prototyping machine to produce the various components

USB Flash Pen Drives

Being about the same size as the standard pen, USB pen drives, most popular added feature to date is its MP3 playback function. A lot also have an LCD display for track browsing, and audio input jack and a rechargeable battery. The newer models also offer up to 10 hours voice recording and may even come with tiny speakers for added functionality.

Further, a lot of pen drives come with card reader support for portable memory formats. Some of the newer pen drives can double as a Web cam and a still camera because they have tiny camera lenses for snapping low resolution pictures. These units also come with mountable stands and for greater functionality as Web cams.

USB pen drive applications may also be used to allow the user to save desktop configurations, documents and even bookmarks and makes for easy accessibility and transfer from one computer to the next. It only takes a minute to display the personal settings and data from the previous changes including the updates and changes that you have saved in the USB pen drive.

LCD Monitor vs CRT Measurements

Now take a ruler or tape measure, and measure the actual image you are viewing, measure diagonally, and you will see that the actual measurement is smaller than the monitors claimed size. For example, my 19 inch CRT monitor, measuring the actual image from the bottom left hand corner of the picture to the upper right hand corner is actually 17.25 inches, or in other words, only .25 inches larger than 17 inches, if the monitor measurement were the actual viewing screen this 19 inch monitor would only qualify as a 17 inch LCD monitor. This is where the LCD measurement comes in.

LCD monitors are measured by actual viewable area of the screen. They do not have a large rounded out tube beyond the screen, it is a flat panel of Liquid Crystals behind which are a series of tube lights that shine through the color crystals to illuminate your display. A 17 inch LCD monitor is 17 inches diagonally, a 19 inch monitor is 19 inches diagonal or about 1.75 inches larger than my example of the CRT tube.

Another little known glich in monitor measurements is how the diagonal measurement of a

Google’s Pixel 4

The Pixel 4 adds some more AI-powered smarts, relying increasingly on its software to determine the overall look of the final image. And while the camera has some moments where it’s truly excellent, I ran into a few growing pains as Google tries to calculate its way to perfect photos.

What’s new?

On paper, the Pixel 4’s camera doesn’t seem all that different from the hardware that came before it. The primary exception is the notable addition of a telephoto lens, which Google intends to improve performance specifically when it comes to zooming and portrait mode. The shooter’s competition, however, is stiffer this year: Apple seems to have corrected some the over-zealous HDR tech that made iPhone XS images look unrealistic and unnatural at times, and the Cupertino company promises to further improve the iPhone 11 Pro’s already-very-good camera when its detail-enhancing Deep Fusion tech arrives in the next iOS update.


Continuous Ink Systems

Continuous Ink Systems were introduced in 1999, however have had a significant growth in the consumer market over the last few years. The problem associated with regular ink jet printer cartridges is the cost. The price of cartridges varies depending on the printer model and brand. However because cartridges contain very little ink – there is very little value.

Continuous ink systems use ink tanks which are designed to sit beside a printer. These ink tanks can contain up to 100x the amount of ink compared to regular ink jet printer cartridges. Unlike most cartridges, CIS ink tanks can be refilled one-by-one. The fact that CIS contain much more ink, means that you don’t need to replace ink every few weeks.

Continuous ink systems result in a saving of approximately 90% due to the bulk feed. This means that the consumer can print photos and other media without having to worry about ink usage and the high costs of cartridges. In today’s age, people own expensive digital cameras and have the convenience of printing excellent quality image from their homes. CIS finally give consumers the freedom to print their media in an affordable and efficient way.

Megabites Of Memory


Memory is the ability to retain data for a period of time. Memory can be built right into a system board, but it is usually attached to the system board in the form of a chip or module. Memory chips are tiny electronic circuits specially designed for storing data. Memory chips reside on the motherboard, or on a added memory boards inside your PC. Memory is very easy to install in computers, but be sure you buy the correct type of memory. Memory upgrades should be compatible with the memory already in your computer, and they must be compatible with the motherboard in your computer.


Computers generally come with no less than 256MB of memory for a basic computer. You can upgrade that to 512MB or more with the addition of one or two modules. Although older computers may not support that much. To installing CD-ROM drive you need about 740MB of hard drive space to copy CDs. Video cards have a built-in memory but they also consume your main system RAM. If you add a printer or scanner to your system, you should also consider buying more memory. Computer memory is always
