Embroidery Digitizing Basics

Embroidery Digitizing Basics

Machine embroidery has been around for many years. However, all of the machine embroidery of the past was done by very large and expensive machines housed within specialty businesses. In the past if you were a business and wanted your logos sewn onto baseball hats or other promotional items, then you went to a custom embroidery business and they did it for you. Thanks to the declining costs of computers and technology advances, home sewers now have the capability of doing custom machine embroidery in their own homes.

The art of creating custom machine embroidery is called embroidery digitizing. Embroidery digitizing involves using a personal computer, an embroidery sewing machine, and a special digitizing software application.

Using digitizing software install on your personal computer, you can transfer a design into one which can be embroidered. However, this is not a simple “click-of-the-mouse” conversion; it is done by hand and takes some time and skills. To digitize a design you need to dissect the design into sections and layers and design how each area will look with another.

Once you have your basic design digitized, you then have to spend time with the special software tools tweaking out the design so that it will look good once your embroidery machine embroiders it. Because thread embroidery designs are three dimensional not all designs will look good once they have been digitized. The software is very helpful in this area and in showing you which areas to change.

To be successful with embroidery digitizing software you must be an experienced sewer and knowledgeable of the various types of fabrics on the market. Fabric moves differently when sewn and you will have to account for this in your designs.

Embroidery digitizing software requires you to have a fairly powerful personal computer. You will need one with a lot of system memory, a strong processor, a USB port, and a lot of free disk space. The better the personal computer you use, the easier it will be for you to design your embroidery projects and the easier it will be for your computer to transfer them.

When you are looking to purchase digitizing software there are a few things you should be looking for. The first is that the software itself should be easy to install and use. You should be able to digitize on your computer screen by being able to control scaling, match components to the onscreen grids, zoom in and zoom out, and pan from one area of a design to another.

Many digitizers today can easily allow you to expand or shrink your designs and they will automatically adjust your stitch count and density to meet the new design size. This is very important and can save you a lot of time.

Another important thing you want to have in your digitizing software is the ability to see the true thread colors both on your computer monitor and on your color printer. This allows you to make sure you use just the right colors in your designs and that the embroidered design meets any logo requirements as well.

As you can see, computer digitized embroidery is not a simple process. However, once you learn the basics it can be a very satisfying craft or business venture for you. You will be truly amazed at your results after learning the software and creating your first few designs.

Bluetooth Headset Basics Revealed

Bluetooth Headset Basics Revealed

What is a Bluetooth headset? You’ve certainly seen them, those things connected to people’s ears that make them look like they just walked out of a Star Trek convention. At first glance, it almost looks like a giant bug has attached itself to the side of the person’s face, causing a moment of alarm as one prepares either to help the poor victim or run for cover. Other times, people walk down the street, apparently talking to themselves in either calm or vigorous tones. It isn’t until a quick turn of the head reveals a Bluetooth headset.

A Bluetooth headset is an odd name for what this little gizmo is and does. First of all, it’s usually not blue, it doesn’t have anything to do with teeth, and it isn’t really a headset: it fits around the outside of your ear like sleek CD player headphone earpieces. With a Bluetooth headset, nothing gets draped around the neck or over the head.

A Bluetooth headset, in English, is a wireless device that connects one to mobile phones, PCs, laptops, digital cameras, printers and even video game consoles. It has global range capabilities and a short-range radio frequency. The distance a Bluetooth headset can pick up frequencies is determined by the power of the transceiver microchip inside, and most headsets can pick up anything as long as the other party or object is in range. The Bluetooth headset device also uses a radio communications system, and as long as the signal can be picked up, so can you. Be advised however, that in order to make a Bluetooth headset work, you need to meet certain specifications, and your Bluetooth headset must be compatible with that of the person or device with which you wish to communicate. Make sense?

One of the most positive aspects of Bluetooth headset capability is that it allows hands-free use. Especially with new laws on the books regarding people driving with cell phones, a Bluetooth headset offers a safe alternative, and yet allows necessary communication between parties or hardware. Believe it or not, a Bluetooth headset can also communicate with a PC mouse, printers and keyboards. A Bluetooth headset also allows users to transfer data from the headset to a destination such as a palm pilot as well. The younger groups will appreciate the fact that a Bluetooth headset can control gaming consoles such as Playstation 3, Nintendo, and new Wii technologies.

Bluetooth technology isn’t limited to the Bluetooth headset. It’s also found in just about any newer types of electronic and computer equipment being manufactured today. Even Wi-Fi uses the same frequency as a Bluetooth headset, while Bluetooth technology is more user friendly. First designed in 1994 by two Swedes, the original company now has thousands of companies worldwide. Major global companies such as Intel, Nokia, Sony and IBM have all taken advantage of boom in Bluetooth technology and developed products and services to support it. So, a Bluetooth headset is much more than a cute little mobile phone that fits over your ear. A Bluetooth headset is riding the crest of the wave into the future.

Home Theater Surround Sound Basics

Home Theater Surround Sound Basics

Major movie houses, theatres, home entertainment environments, gaming, arcade and other public and in-house presentation areas today use surround sound systems for enhanced audio entertainment. Surround sound is basically when you increase the dimension of your sound (or sound waves), sort of like on the Twilight Zone. In other words you take the standard one dimensional audio production, referred to as mono / Left-Right, and turn it into multiple dimensions; two or three.

Sound Systems

To create surround sound, you can go any one of several different directions. The simplest and probably the oldest way, would be to set up a bunch of speakers surrounding the audience, so that the sound comes in to the listeners from all over, from the different directions.

A different method is to combine the use of headphones with localized audio production with psychoacoustics. The result is a simulated three-dimensional effect.

And another way to create surround sound is with ambisonics where you reconstruct the sound at a central point. However, you get a gradual decline in quality as you move outward.

Still another way is to use wave field synthesis (WFS), with multiple loudspeakers and a computer aid.

Popular today are everyday devices like stereo, PC soundcards, some camcorders and AV receivers. These feature digital signal or audio processors that create surround sound via stereo sources, or have add-ons, as in some camcorder cases.

Formats

Just as nothing stays the same, ditto with sound formats. Top ones have included
discrete 5.1 Surround sound format with DVD-Audio, also known as DVD-A and SACD which stands for Super Audio CD. Moving on you have ambisonics, quadraphonic then Dolby 5.1 Surround sound. And later are: DTS, DVD-Video or DVD-V and the latest MP3 Surround.
