Tips for ensuring your old gadgets works before selling them

Selling your old devices is a great way to get rid of the electronic clutter lying around your house. Also, you can also make some money from selling these gadgets. Many sites buy used electronics from consumers, and they offer a fair price for them, including the ecoATM.  If you have a lot of old gadgets in the attic or the storage room, here are four tips for making sure they’re in working condition when you sell them to your preferred buyer:

1) Test every feature before putting your device up for sale

When it comes down to it, all that matters is whether or not the gadget works. If it doesn’t turn on, no one will be interested in buying it – no matter how good its specs are.

To be sure that your gadgets are in working condition:

v Test every button and feature on the device.

v If it comes with a battery, make sure it charges properly.

v Check to see if all of its features are functional – including Wi-Fi, and Bluetooth.

If you aren’t completely certain about the device’s working state, consider asking a friend or family member who is well-versed in technology for help. For example, someone from PC Mag can help assess whether or not an old laptop will run Windows 7 correctly after being updated with the newest drivers.

2) Backup all of your device’s files

Before putting up any used devices for sale, back them up on a microSD card or an external hard drive so that you can recover data in case anything happens during shipping. If possible, remove the battery when storing the gadget – this will prevent any battery leakage.

3) Sell your device for at least 50 percent off its price

If you’re trying to sell an old gadget online, then the first thing you should do is set its price at around 50 percent of what it was initially worth. In reality, numerous people might be looking for something cheap, so setting a reasonable price would mean more people will be interested in buying your device. For instance, if you are interacting with ecoATMs near me and someone has sent you an email expressing their interest, then you can negotiate further.

4) Deactivate your gadget before selling them online

Most people don’t realize this, but many devices come preloaded with software that tells your wireless carrier where you are. Such software may also cause problems with the device’s battery life if it’s not deactivated beforehand.

You should be able to find instructions on how to deactivate these programs online. If you’re not sure which programs are causing the problem, then look through your gadget’s menus for any suspicious programs that might be sending your data back to its manufacturer or wireless carrier.

For instance, some smartphone features allow people who have their phone in their possession to track down where they are by using GPS tracking. Due to that, if you want to sell an old smartphone without getting tracked down by the new owner, you should disable this program before selling it.

What are the different types of materials used in precision machining?

A precision machine produces items with a high level of accuracy and consistency. Several factors must be properly optimized, including the speed and feed rate of the cutting tool, spindle power, and lubricants used to ensure optimal performance to achieve that. Beyond these technical specifications, there are other benefits to using a precision machine for manufacturing. Compared to those areas where re-tooling costs are especially high, precision machining services near me can offer clear advantages over other forms of production methods, and it involves using different materials. The following is a list of common precision machining materials:

Plastics account for approximately 1 percent of all raw materials used worldwide. The exact amount is hard to determine because some types can be recycled while others cannot. Plastics come from natural sources (such as wood, plants, and petroleum) or synthetic sources (such as oil refining). The most common plastics used for manufacturing purposes are the hard, unplasticized variety known as thermosetting resins.

Examples include Bakelite, Celcon, Delrin, nylon, polypropylene, polyethylene terephthalate (Dacron), Teflon fluorocarbon resin, Lexan polycarbonate resin, and polyvinyl chloride (PVC). Other plastics are often foamed to reduce weight or improve thermal insulation. Examples of foam plastics include beadboard, Styrofoam pellets, urethane, cellular rubber, and phenolic resins.

Plastics are used in precision machining because they are easy to machine, resistant to abrasion, not conductive, and can transmit heat without conducting it away from the surface being worked on. Plastics are available in a wide range of hardness so that surfaces can be machined to any desired degree of smoothness or tooth. Further, plastics can be specially colored or finished for aesthetic reasons. Steel is useful in precision machining because it machines precisely due to its hardness, affordability, and alloying can alter its properties.


Research indicates that steel accounts for approximately 95 percent of all raw materials used in modern industrialized countries. The world produces more than 1 billion metric tons annually. This production rate makes it difficult to determine exactly how much steel has been produced at any time during the past century because revisions constantly occur as new data becomes available. Although more than 768 million tons of steel are produced worldwide each year, recycling efforts have reduced the need for new production. The most common form of steel is carbon steel, which may be alloyed with chromium, manganese, nickel, or other elements to improve its properties.


A commonly used material with good machinability, strength, and corrosion resistance, can be annealed or work hardened. It is not as strong as steel but has better wear characteristics (less friction). Brass can be cut dry or wet (with lubricant) to offer a smooth finish and polish well once finished. Brass has excellent dimensional stability and high electrical conductivity, making it ideal for applications that require accurate parts and precise electrical connections, such as precision sensors and switches. 


Aluminum is a low density, non-corrosive metal alloy with good strength to weight ratio. Aluminum is easily machined and formed in annealed condition; it has excellent corrosion resistance, is lightweight but stiff. It can be finished by some abrasion methods (abrasive blasting/shot peening, bead blasting). That will produce a satin finish which may need further finishing before painting or assembly. A variety of aluminum alloys are commonly used for precision parts. Each alloy type provides different hardness, ductility, and mechanical properties that make them suitable for particular precision fabrication applications, such as abrasion resistance (aluminum bronze) versus stiffness. 

What Should You Know About Lifeline Programs?

Lifeline phone program Oklahoma can make a significant difference between death and recovery. Having a cell phone will facilitate communication and seeking assistance at a good time. Many people in the past have been rescued as a result of using wireless lifeline cell phones.

Beneficial for low income and elderly people

The cellular lifeline phone services allow low-income people to fulfill the need to communicate: the program helps anyone without the financial ability to own communication devices like a mobile phone. For many of the participants, minutes and handsets are free. Despite being allotted a few minutes to you per month, the program assists in emergencies to seek help faster.

In addition to minutes, the program offers unlimited communication to 411 and accessing 911 and the phones used for the calls. The program in some states has features like call waiting, voicemail, and caller ID. Some offer exceptional services that include facilitating international calls and allowing anyone to buy prepaid or additional minutes.

Do your research on the quality of services

Suppose you contemplate using the cellular lifeline program, a lookout with your state or region to confirm availability. Choose top-rated service providers. It is advisable to select reliable services to ensure there is efficient communication. Ensure you look into more than having good minute plans to make sure you can effectively communicate at any time. Check out the website of the service providers to determine if there are any complaints.

There are several scenarios where having a lifeline phone helps in times of crisis. The lifeline phones are especially beneficial for low-income families and older adults: such people are primarily incapable of owning a mobile device to assist in times of emergency and crisis. As a result of realizing the need to promote communication, state and federal governments have established a cellular lifeline program.

How Do Magnetic Stirrers Work?

Just about any well-equipped laboratory, these days should have magnetic stirrers on hand. Magnetic stirrers are easy to use, affordable, and allow for consistent mixing and dispersion. Perhaps best of all, you can set up magnetic stirrers and ensure that substances continue to mix even as you move on to other tasks.

Show magnetic stirrers to a young child, and he or she might think it’s magic. While technology often does seem magical, magnetic stirrers aren’t particularly mystic. These stirrers use rotating magnetic fields to spin a stir bar that’s been placed in your beaker or another container. As the stir bar spins, it’ll mix up the liquids.

If you’re going to use a magnetic stirrer, you’ll typically need a power source. That may include batteries, a simple plug, or whatever else. Electric motors are normally used to rotate the magnet fields (often simply by moving the magnets) thus spinning the stir bar.

Magnetic stirrers generally work best with smaller amounts of liquid (4 liters or less). While magnetic stirrers are very effective and easy to use, there are some limitations. The center of your solution, for example, will often be very well mixed. The top and outside of your solution may not be.

Particularly thick, or viscous, materials also won’t mix well with magnetic stirring. Thin, watery substances, on the other hand, are often very easy to mix with magnetic stirrers.

In some cases, you can use different stir bars to improve mixing. One stir bar may work better with a solution than another. Fortunately, science and chemistry supply companies often sell a variety of stirrers. This way, you can select the one that works best for you.

Magnetic stirring devices often come with hotplates and other features too, making them multi-faceted tools that are useful for a range of applications.

The Structure of Inertial Navigation Systems

An Inertial Measurement Unit comprises gyroscopes, magnetometers, and accelerometers, and they measure angles in the axis to obtain a roll or pitch. In addition, the navigation sensors can integrate an internal or external receiver for navigation data and velocity. Most of the inertial measurement units are based on a technology that combines high performance and low power on a small size.

Gyroscope: Refers to a physical sensor that measures and detects the angular movement of objects relative to the inertial reference frame. It measures the motion without the help of a reference signal.

Accelerometer: It is the instrument that measures the proper acceleration related to a free fall that people and objects feel. The accelerations are measured by gravitational force and can detect temperature, velocity, altitude, position, and magnetic fields.

Magnetometer: It is a sensor used in the measurement of the direction and strength of magnetic fields. The measurements help to provide the correct bearing of the Inertial Navigation Systems.

Advantages of Inertial Navigation Systems

The systems are autonomous and do not depend on the surrounding environment and external aids. It is for this reason that they can operate underwater and in tunnels. Inertial Navigation Systems are well suited for integrated guidance, navigation, and control of the host vehicle. The system’s measurement unit can measure variables such as net acceleration to estimate the speed of a host vehicle.

The inertial system is used in surveying to collect data that is important for decision making. For example, inertial sensors can be integrated into indoor and mobile mapping surveys. It is also used for applications that need high accuracy and machine language, such as operating driverless cars.

The systems are used in the defense department for antenna pointing. They can also be used in marine applications that include hydrography and submarines. Navigation systems are, however, costly. In addition, it is expensive to acquire, operate and manage inertial navigation systems.
