An Affordable Digital Multimeter For The Electronics Enthusiast

By blogger on

The multimeter is one of the most useful pieces of electrical test equipments. As it can measure amps, ohms and volts. Its true, it really combines three functions. When you need to measure current, it becomes an ammeter. When you need to measure ohms, it becomes an ohmmeter, while you need to measure voltage, it becomes a voltmeter.

You can imagine that digital multimeter can be used in industrial applications, electrical applications, diagnose your vehicles or home usage. Multimeters come in two parts: digital and analog. The analog one has a needle, while the digital one has a LED or LCD display. We know digital products always in advance, and has trend that is to replace the analog ones. The digital one not only can be readout directly, but also can be adjusted automatically.

The types of digital multimeter come in two kinds, one is handheld, another one is desktop. In fact, multimeter are used very frequently, handheld digital multimeter will be more practical than desktop one. In other hand, handheld multimeter is much cheaper than desktop multimeter.

There is a price range of digital multimeter from several dollars to several thousand dollars. The price you pay all depends on what features you need, and how much you are willing to spend. However, if you are a beginner engineer or enthusiast, it is suggested that you neednt buy an expensive one, or it will lead a waste. You dont be worried, as any digital one has a function with measuring current, ohmmeter and voltmeter. You can buy a good brand with affordable price, such as Hantek digital multimeter.

If you are looking for a digital multimeter to begin your career or for your hobby, dont be hesitated, youroscilloscope.com will offer you more choices. You might want to know more specific details about digital multimeters in my other reviews.

Radio Controlled Helicopters

By blogger on

Radio controlled helicopters (also RC helicopters) are model aircraft which are distinct from RC airplanes because of the differences in construction, aerodynamics, and flight training. Several basic designs of RC helicopters exist, of which some (such as those with collective pitch, meaning blades which rotate on their longitudinal axis to vary or reverse lift) are more maneuverable than others. The more maneuverable designs are often harder to fly, but benefit from greater aerobatic capabilities. Flight controls allow pilots to control the collective and throttle (usually linked together), the cyclic controls (pitch and roll), and the tail rotor (yaw). Controlling these in unison enables the helicopter to perform most of the same maneuvres as full sized helicopters, such as hovering and backwards flight, and many that full sized helicopters cannot.

The various helicopter controls are effected by means of small servo motors, commonly known as servos. A piezoelectric gyroscope is typically used on the tail rotor (yaw) control to counter wind- and torque reaction induced tail movement. This gyro does not itself apply a mechanical force, but electronically adjusts the control signal to the tail rotor servo. The engines typically used to be methanol-powered two-stroke motors, but electric brushless motors combined with a high performance lithium polymer battery (or lipo) are now more common and provide improved efficiency, performance and lifespan compared to brushed motors, while decreasing prices bring them within reach of hobbyists. Gasoline and jet turbine engines are also used.

Common power sources are nitro (nitromethane methanol internal combustion), electric batteries, gas turbines, petrol and gasoline. Mechanical layouts include cyclic/collective pitch mixing (CCPM) in all power sources, fixed pitch electric rotors and coaxial electric rotors. Practical electric helicopters are a recent development but have rapidly developed and become more common, overtaking nitro helicopters in common use. Gas turbine helicopters are also increasing in popularity, although the high cost puts them out of reach of most people.

Nitro or glow fuel helicopters come in different sizes: 15, 30, 50, 60 and 90 size. These numbers originated from the size of engine used in the different models (0.30 cu in, 0.50 cu in and so on). The bigger and more powerful the engine, the larger the main rotor blade that it can turn and hence the bigger the aircraft overall. Typical flight times for nitro helicopters is 7-14 minutes depending on the engine size and tuning. The maximum height of operation for RC helicopters, be it nitro or electric, is only limited to the height at which the controller can see the model. Most radio systems have a range of over a mile, and the person controlling the model will have long lost sight of the model.

Two small electric helicopters emerged in the mid 1990s. These were the Kalt Whisper and the Kyosho EP Concept, flying on 7/8 1200 mah NiCad batteries with brushed motors. However, the 540 brushed sized motors were on the limit of current draw, often 20-25 amps on the `hotter’ motors, hence brush and commutator problems were common. S107 metal series Recent advancements in battery technology are making electric flying more feasible in terms of flying time. Lithium polymer (LiPo) batteries are able to provide the high current required for high performance aerobatics while still remaining very light. Typical flight times are 4-12 minutes depending on the flying style and battery capacity.

Small fixed pitch helicopters need a 4-channel radio (throttle, elevator, aileron, rudder), although micro helicopters that utilize a 2-channel infrared control system also exist; while collective pitch models need a minimum of 5 channels with 6 being most common (throttle, collective pitch, elevator, aileron, rudder and gyro gain). Because of the normal interaction of the various control mechanisms, advanced radios include adjustable mixing functions, such as throttle/collective and throttle/rudder. RC Helicopters usually have at least four controls: Roll Cyclic Pitch, Elevator (Fore Aft Cyclic Pitch), Rudder (Yaw) and Pitch/Throttle (Collective Pitch/Power).

Use Caution When Shopping Online For Electronics

By blogger on

In this day and time it’s getting a lot easier and more convenient to shop online for electronics, but you must take certain precautions when you are visiting consumer electronic websites. One thing to remember is that all websites are not created equal and their are some things I want to point out to you that will help you a great deal when you are shopping online.

How does the website look?

Does the website look like it’s something that your little brother or sister tried to put up in one day? It takes a lot of time to build a quality website that’s neat and easy for you to navigate and understand. Also on the other hand you don’t want to get to a electronics website and to be bombarded with too much information. This is something that I see a lot of today.

The website should be simple, safe and easy to navigate. Their’s nothing more frustrating than to go to a site that’s not working properly.

Are the links working on the website?

How many websites have you been to and the links are not working properly? This is a huge red flag if their are links that give you that dreaded 404 error code. A well run electronics website should never have any bad links. If you come run into this problem simply e-mail or contact the owner stating the problem that occurred. The owner way even give you a special discount for doing so.

It’s a very uneasy feeling if you go to a website, whipped out you credit card, clicked on the item you wanted to buy only to find out the link doesn’t work? I don’t know about you, but my credit card would quickly go back into my pocket! Then I will be looking for another online electronics website to shop at.

Does the website have security banners?

Make sure the website that you would like to make a purchase has taken some security measures to safe guard your information. Most of the security seals or banners are located in prominent area of the website, usually on the top right hand side and at the bottom. If you don’t see this most likely this particular website doesn’t place high regard to your personal information.

Read all of the information that is in the privacy policy. The privacy policy will state what the website does with all of the information that it receives from you. You should avoid making purchases on sites that doesn’t have this basic information.

These are some simple and practical steps that you can take that will save you a ton of grief. It’s best to do an internet search on the site if you feel uneasy about it in any way. If the bad outweighs the good just simply move on to another electronics website.

Hope the tips that I shared with you will help the next time that you go online to shop.
