40 years of mobile phones

Ricky Williams Mobile Leave a Comment

There have been quite a few posts on T3KD lately talking about the mobile industry. Where is it going, what new hardware is out, better battery life, etc. So I thought with all this talk about better battery life among other features we’d love to see. Why not take a look back since it’s now been 40 years since the first mobile phone call was made. A look back that might bring perspective on how far we’ve come and why we don’t have it so bad after all. So Gizmodo did a post on the 40th Anniversary of the first mobile call with a Yahoo post expanding even further on the information. They are both definitely worth a read and could possibly bring back some nostalgic feelings, if you were alive back then or older than 10 years old. I wont re-hash everything in the posts but instead highlight the important thing that struck me about how far we have come in the 40 years of mobile phones. I’ll also include a Motorola video that pretty much predicted the mobile phone trajectory in the future which is now our present! The first call was made by Martin Cooper, April 3rd …

Custom computer: Installing a motherboard in case

Matthew Mallicoat Tutorial Leave a Comment

The next step of building a custom computer is here. In the last article, we covered how to install RAM and the CPU and heatsink. From here we will cover how to do everything in your case and do it in the way that is easiest. Obviously, the case makes for moving around a little more difficult, so we will begin by hooking up on the outside first. Installing the power supply of your custom computer Today, there are three common ways to mount a power supply: on the top, on the bottom and on the smallest cases, in the front of the computer so the power supply rest vertically and extension cord is used to plug into the back of the case. Obviously, the latter is very unusual in building a custom computer. In the case of installing all the top and the bottom, there is usually only one way to install power supply of your custom computer. On the back of the case there will be four screw holes, one for each corner, and yet one of the screw holes will be a little more towards the center of the power supply. Some power supply mounts allow you …

Custom computer: Installing CPU, Heatsink, and Ram

Matthew Mallicoat Tutorial 1 Comment

In the latest series, we’ve been expanding on building a custom computer. At last we are here, the building of your new and custom computer. This is actually one of the easiest steps, you follow some very simple guidelines. Remember that computer components are very sensitive to electrostatic discharge and you should take care to not expose your components, especially the motherboard, to this electrostatic discharge. The most common way is to simply types any exposed metal, so as to get rid of any lingering charge. If you want to be even more safe, you can use a special strap which affixes your wrist and gets rid of it. Building a custom computer: Begin by opening up your case and locating the standoffs, which are little bronze pieces that you screw into the case and were the motherboard screws into. This creates a barrier between the case and actual motherboard. Be careful to only put the standoffs where there is a corresponding hole on the motherboard. The I/O shield snaps into the case itself and forms a barrier between the outside and inside of the case. But before actually installing the motherboard, it may be a good idea to put …

Building a Custom Computer: Cooling

Matthew Mallicoat Tutorial Leave a Comment

Cooling your computer Cooling is important, as the enemy of any electronics is heat. By effectively dispersing heat, you can prolong the life of your components.  A CPU heatsink will disburse heat away from the processor, which will reach 300°F if left without a heatsink. CPUs run best when they’re cool, so it is important to choose one that is able disburse heat effectively. Case fans are mounted on the inside of computer cases and based on how they are oriented they either push or pull the air. CPU Heatsinks and liquid coolers Currently, a liquid cooler uses some form of liquid to circulate through tubes and cool the CPU. This form of cooling is much quieter, as there are no heatsinks and fans to be concerned with, unless you count the radiator fan that is mounted on the case itself. Liquid cooling is also much more expensive than using a CPU heatsink and fan. Fan cooling can be just as effective as liquid cooling without the cost he sinks are basically sheets of metal stacked with space in between, so that air may blow between them. Heat pipes are run through the sheets of metal and rest on top …

Power Supplies It is important to choose any type of power supplies, as an improper power supply can run the risk of damage to your components. There are several things to consider, but for the most part, choosing a power supply is pretty easy. Follow the guidelines below and you will be sure to find one that suits all of your needs. Wattage: Wattage refers to the amount of power that a power supply can handle. For the most part, a power supplies optimum range is around 60 to 70%. Power supplies can range from as low as 300 W to as high as 1500. 1500 W is for the most part, overkill and very expensive. For the average user who doesn’t need very much, 300 to 500 W is more than enough. If you are planning to add a graphics card, then you should add a 500 to 750 W power supply. If you want to add more than one graphics card, anything over 750 W should be sufficient. Modular versus non-modular: Non-modular power supplies have all the connectors you can ever use attach the power supply. These types of power supplies are much less expensive than modular power …

Building a Custom Computer: Choosing the Right Hard Drive

Hard Drives: What To Choose The hard drive, the main storage device for the computer, is the next component that someone needs to consider when building their computer. You want to make sure that you choose a hard drives that is stable, fast enough for your needs, and holds enough. There are many different options that you can choose, but for the purposes of this tutorial, we will be looking at solid-state drives and hard disk drives. har  Solid-state drives: Solid-state drives, or SSD’s, are the new players on the block. Anyone who has ever used a flash drive has used the technology behind SSD’s. This allows solid-state drives access data much faster than traditional hard drives, it is argued that a last much longer as well. On the other hand, since this technology is so new, it is still much more expensive per gigabyte for SSD and for traditional hard drive. However, many users choose to use an SSD as a ‘boot drive’, or they choose to install the operating system on that drive and a larger HDD as their primary source device. While looking for solid-state drive, look for both reading and writing speeds. If you choose to …

Building a Custom Computer: The Motherboard

Matthew Mallicoat Tutorial Leave a Comment

The motherboard is the next part someone needs to consider. The motherboard is one of the most important and one of the most forgotten parts in the computer. Be careful to not bottleneck, in other words, don’t spend so much on one component that other components go neglected. After all, a computer is only as fast as the slowest part. Form factor Form factor may sound complicated, but simply put, it is a configuration of the motherboard and how many expansion slots are available on the motherboard. It is the size. Smaller motherboards will be able to fit in smaller cases, thereby reducing the weight of the or moral system. However, this also means that their ability to expand is more limited. The standard size or form factor is ATX. There is also XL ATX and micro-ATX. Socket This is the next most important consideration. The socket refers to the point that the processor plugs into the motherboard. After you’ve chosen your processor, make sure you choose a motherboard that will fit your socket. Some sockets will only fit a handful of processors, while other sockets serve many more. Make sure you research and make sure that the socket you …

Choosing a Processor

Building a Custom Computer: choosing a processor

Matthew Mallicoat Tutorial 1 Comment

Choosing a processor that works for you While you can start anywhere you wish, is always easier to start with a processor, or central processing unit. There are several reasons for this. The kind of processor you choose, will determine your mother board, the memory you can use and the kind of hard drive you must get. The two processor companies, AMD and Intel, both have fantastic options. However, there are several factors that go into choosing a processor. Socket: The socket refers to how your processor connects to your mother board. Choosing the right socket to fit your processor is extremely important. Intel and AMD both have unique socket types and even within their own range of processors, the sockets will be different. AMD uses pins, while Intel has pins on the board itself. When choosing a processor, this is the most important factor to consider. Core: Cores refer to divisions within the processor itself, so choosing a processor isn’t just about speed alone. That is, there are smaller processors within the main processor. That means that the processor can handle more than one task at a time. Hyperthreading is a process that allows a computer to see each …
