How it works – OBD2 Scanner

OBD II Scanners are devices that are used to access car OBD (on-board diagnostic) information. They are found in most cars and light truck models released in recent years. During the late 70s and early 80′s, motor vehicle manufacturers started using electronic methods to control the functions of motor vehicles as well as diagnose engine problems.

The primary reason for this was to meet EPA (Environmental Protection Agency) emission standards. Over the years, OBD II Scanners became more sophisticated with a new version coming out in the mid-’90s providing “almost” complete engine control. That same OBD version also made it possible to monitor parts of the chassis, body and accessory devices, as well as diagnose the entire control network of the car.

Prior to the introduction of the OBD II Scanners automobiles had connectors in several positions under the dashboard and the hood. Now, they have a connector located in the passenger-side compartment which is easily accessible from the driver’s seat. The OBD-II J1962 connector has a cable plugged into it and then connected to the OBD II Scanner. A computer in the vehicle continuously monitors all aspects of the car’s operation. As soon as a problem is detected, a trouble code gets saved immediately into the vehicle’s computer memory. Some of these problems automatically trigger warning lights such as the Check Engine light, while others simply store the data as needed.

Consequently, OBD II Scanners can read the DTCs (diagnostic trouble codes) to identify specific problems. When an issue is encountered, the car owner can look up the meaning of the code in display and refer to troubleshooting manuals to find ways of fixing it. The codes’ meanings are normally supplied by the manufacturer in a hard copy, or soft copy which can for easy retrieval via any computer.

Consistent with the OBD II functionality, the Check Engine light on the dashboard is known in the service industry as an “MIL” or Malfunction Indicator Light. It displays three types of signals. When occasional flashes are displayed, this would mean momentary malfunctions. If the problem is serious then it flashes continuously, and this normally occurs when the problem has to do with emissions or the vehicle’s safety. When the MIL has a constant flash, this indicates a serious problem which requires an immediate response. Failure to respond to this state of the MIL alarm can lead to engine damage.

Serious failure signals causes the MIL to be turned ON any time the vehicle is running and will not turn OFF until the MIL is reset or the problem is fixed. Occasional and random failures causes the MIL to light instantly but these often go out before the problem is located. The freeze frame of the vehicle’s condition captured by the computer at the moment of malfunction can be very valuable during problem diagnosis. In some cases if the vehicle finishes three driving cycles without the problem happening again, the freeze frame will be erased.

All of these are handy descriptions of what OBD II scanners can do to make your car safer and easier to troubleshoot. The advances in control technology have allowed more sophisticated control systems to constantly check your vehicle so you will not have to worry when driving.

How to Choose The Best Road Bike

When choosing your next road bike, more times than not, most people are only looking at the price of the bike and not the quality. Although price is obviously important, it is equally important to recognize the value based on the price you are paying for the bike.

Your search for a new road bicycle must begin by answering several basic questions.


There are many places to find used bicycles today. You can find plenty of them for sale on Craigslist in most price ranges. This may be a viable option if you are limited to how much you can spend. Buying a used road bike can pose many problems including knowing about any existing issues the former owner had with the bike. Even though the bike may look shiny and clean there may still be serious problems which may cause a failure down the road.

You must visually inspect all the parts of the bike to see if you can find obvious signs of wear. Everything wears out, but it is the amount of wear and how quickly it wears out that must be taken into consideration. The frame has to be looked at with a careful eye because if there is a small crack in the weld the bike will be virtually worthless.

You can always swap out the components yourself if you have the capacity to do so. Your local bike shop can do this but at a much higher price. These are just some of the problems with buying a used bike. Imagine the kind of injuries you could get if the brakes failed while you were riding.

Mid-Range Price VS Low-Range Price

You can categorize road bikes relative to their pricing so in this article we will focus on the mid to lower-range road bikes. Road bikes generally range in price from 200 to 400 dollars for the low range and 400 to 1200 dollars for the mid range. Now you may say that 1200 dollars is a lot of money for a mid range priced road bike but when you take into consideration that you could pay upwards of 10,000 dollars for a higher priced road bike it doesn’t seem so high.

The difference between these bikes is the quality of the frame, crank, derailleur, gears, brakes, tires, seat, head post, handlebars etc. So basically the overall quality of the bikes will be as different as night and day. Although you will be probably be getting a Shimano derailleur on both bikes you will be not be getting the Shimano XTR Shadow on the low priced road bike. This holds true for most of the components on the road bike.

If you don’t care then the least expensive bike might be the right choice for you. An example would be, if you couldn’t afford the higher priced Schwinn Laguna road bikeyou could instead look at the lower pricedRapido by Lamborghini. Both are excellent road bikes and for a beginner the Rapido may be just what the doctor ordered. If you can afford something in between, theTommaso Monzamight just be the road bike for you.

Repair Costs

Considering the cost of component replacement can you say that you really saved any money. To replace the derailleur will cost you anywhere from 100 to 200 dollars and more depending on the bike shop and the derailleur you choose to replace it with. The same holds true for most of the components on the bike. The original price of the road bike will be far exceeded by the cost to replace it’s components.

The rule of thumb is that if you buy cheap you get cheap.

Embroidery and Needlework

For many years now, embroidery remained popular for leisure pursuits and commercial ventures. It’s an excellent way to customize or personalize belongings and garments to suit fashion, taste, and inclination. Different designs are created on fabrics and other materials with the use of needlework. You can use a manual or a basic sewing machine or you can also use the latest computerized embroidery machines.

Modern embroidery is now complex and intricate. You can create various patterns in a couple of minutes instead of spending hours and days working on it manually. Portable units are usually about 180 pounds and less than thirty inches (width). You can find machines that operate quietly and so you won’t disturb anyone.

The threads used in these machines are rayon or polyester. Like the sewing machine, the embroidery machine also has a spool and bobbin for the stitches. For enhanced outcomes, you can make use of stabilizer and backing; these provide stability and support to your projects. You can do different stitches using the machine like running, fill, underlay, and satin.

The modern machines are usually equipped with patterns and designs. Some of the designs allow you to include dates or lettering for special events. You will simply enter the design on the computerized machine and the machine will do the stitches for you.

Even if you’re a newbie, you can create beautiful patterns. If you want to take embroidery seriously, then it would be best to take embroidery classes so that you will learn the basics and other placement techniques; you will also learn more about hooping caps, correct threading and adjustments, and other similar tasks.

You should know how to operate the software so that you can use the machine with ease. There are factors that affect embroidery like design quality, size, quantity, thread type, and material. All these things should be considered carefully so that you can start creating masterpieces.

Find the perfect embroidery machine now so that it will not take weeks or months to finish a project. If you’re going to use the machine at home, you can buy the basic embroidery machine but for those who are planning to invest in an embroidery business, perhaps you might want to consider the commercial type machines so that all the stitching tasks are handled properly and on time.

Embroidery is more fun these days so you’d better get your very own machine now.
