An Introduction To Computer Printers and Scanners

vote

The article covers various types of printer and scanner technologies available today. The technology behind the working of laser printers is discussed extensively. The contents are provided below:

1.1 What are printers?

Printers are commonly used output devices that produce a hard copy of document stored in electronic form, i.e they put information from computer on to paper.

There are various kinds of printers available today like Impact printers, Bubble-jet printers, Laser printers, Thermal printers etc.

1.2 Types of printers

1.2.1 Impact printers

Impact printers are among the old printing technologies, which make use of inked ribbon to make an imprint on the paper. Impact printers are considered noisy when compared to other printers.

The most commonly known impact printers are:

How Daisy-Wheel Printers work?
A Daisy-Wheel Printer works on the same principle as ball-head typewriter. The daisy wheel printer consists of a disk made of plastic or metal on which characters stand out along the outer edge. The printer rotates the disk to print a character until the desired letter is facing the paper, after which a hammer called solenoid strikes forcing the character to hit an ink ribbon making a mark of the character on the paper.

Their speed is rated by cps (number of characters per second).

Wireless Antenna Types

vote

There are three main categories of antennas:

Omni-directional - Omni-directional antennas radiate RF in a fashion similar to the way a table or floor lamp radiates light. They are designed to provide general coverage in all directions.

Semi-directional - Semi-directional antennas radiate RF in a fashion similar to the way a wall sconce is designed to radiate light away from the wall or the way a street lamp is designed to shine light down on a street or a parking lot, providing a directional light across a large area.

Highly-directional - Highly-directional antennas radiate RF in a fashion similar to the way a spotlight is designed to focus light on a flag or a sign. Each type of antenna is designed with a different objective in mind.

Flash Memory Tutorial

vote

Flash memory is a form of EEPROM (Electrically Erasable Programmable Read-Only Memory) that allows multiple memory locations to be erased or written in one programming operation. In other terms, it is a form of rewritable memory chip that, unlike a RAM(Random Access Memory) chip, power
supply is not required to hold the contents. It is commonly used in memory cards, USB flash drives, MP3 players, digital cameras and mobile phones. Flash memory is also an example of a Non-Volatile Read Write Memory (NVRWM).

Build a PC yourself and save?

vote

Yes, you can still build some PC's for less yourself. Sometimes, a lot less, but only for certain exceptions to a basic rule...

Conventional wisdom once stated that building your own PC was more than just a way to create your perfect computer—it was also a lot cheaper than buying a finished system. However, in recent years economies of scale have overturned this truism, making it nearly impossible for the average individual PC builder to beat a big vendor's price when it comes to a basic desktop system.

Don't believe me? Just try building yourself a Pentium-4 based system for less than you'd pay for any basic Dell Dimension PC.

How to build a Mini ITX Linux PC

vote

This is one sweet and quite tiny DIY system...

My research had led me to believe that the best motherboard choice for my purposes was going to be a VIA EPIA which featured an embedded processor. After talking it over with VIA we dedicided that one of their MII motherboards would be best. Originally I wanted something fanless, like the MII6000, but due to availability we eventually settled on the MII10000. This motherboard features a 1.0 GHz VIA C3/ VIA Eden EBGA processor and the chipset is composed of a VIA CLE266 North Bridge and a VIA VT8235 South Bridge. The motherboard has some extras too, like built-in CF and PCMCIA readers.

HDTV Wonder and 1080i

vote

Recently I decided to make my own quick and dirty HD-DVR by installing an ATI HDTV Wonder. Installation was pretty painless and since I had a ATI Radeon 9200SE I finally got everything working smoothly (Note: in order to get the ATI Multimedia Software installed correctly I had to download the latest drivers from the ATI website).

When I was finally up and running I could watch digital 480i and 720p channels (the included antenna is quite nice since I am about 25 miles from the broadcast station). With the 1080i channels, however, I could see that I had a strong signal and the audio was coming in perfectly but I couldn’t see any video. Also, the 480i and 720p playback was a little choppy - every minute or so the video and audio would skip - it was definitely still watchable, but I wanted to address this problem as well. read more...
