Water Damage Restoration For Electronics

blogger June 25, 2023

Water damage is tough on your electronics. It is factual that water damage is among the biggest problems that make electronic materials to be replaced. On a surprising note, it has been deduced that most of the damage occurring to electronic materials are not caused directly by water itself.

In case there is water damage in electronic materials, if quicker steps are taken, there will be total recovery of such items. Reading through the rest part of this content will help you understand the basis of water damage restoration for electronics.

1. Causes: There are several reasons that can allow water damage in electronic materials. From research and visibility study, spillage and flooding are the most common causes of water damage in electronic item.

With carelessness, water can spill onto electronic materials. For instance, a child can trip and spill water over electronic item. You can also be tripped and spill drinks onto PCs and electronic materials. For smaller electronic gadgets such as MP3 and phones, washing machines can handle the scenario of water spillage. In case there is flooding, the first target of destruction often goes to electronic items.

2. Effects: The presence of water in electronic materials can create several scenarios. To be factual, pure water has no negative action in electronic items.

Basically, water contain other ingredients that are powerful in the destruction of electronic materials. Electrical items can receive short-circuit when there is the presence of minerals in water. Since moisture from the water prevents heat to evacuate the circuit, there is more tension created as required.

This will help the circuit to build excessive heat causing a short-circuit. It is important to know that all of the crevices and grooves found in electronics build a formidable housing for mold. In case the electronic device is not dried immediate, mold will grow overtime in a confinement. The presence of acid and other ingredients found in water can cause reaction for the electronic elements. This reaction can lead to the corrosion of the electronic parts.

3. Prevention: Though, there is little to be done in other to prevent flooding from occurring. Keeping electronic materials 5 feet above the floor is a good idea. Water vaporization can as well cause damage for electronics.

It is a good idea not to drink or eat around any electronic material. You can store electronics in rooms far away from water sources. It is also good to check clothing materials perfectly prior to throwing them into the washer.

Using the explained tips will help you understand the basis of water damage restoration for electronics.

Flybarless Rotor Heads – The Ins And Outs

blogger June 12, 2023

What was the flybar for anyway? The flybar performs three basic functions stabilization, amplificationof cyclic input, and resistance to pitch up in forward flight.

Stabilization: While hovering a wind gust may try and move (tilt) the main rotor. The flybar will be differently (less) affected, and the linkage system will adjust the pitch on the blades to resist the change.
Amplification of cyclic input: When the swashplate tilts and moves the flybar, aerodynamic forcesimposed by the flybar paddles change the spinning plane of the flybar, and again through a series oflinkages this then changes the pitch on the main rotor blades. This means the servos work less hard toachieve a cyclic input.
Resistance to pitch up in forward flight: In fast forward flight the blade advancing into the airflowcreates more lift than the blade retreating in the airflow. This causes a pitch up motion of the helicopter.The flybar again tries keeping in its own plane of rotation, and through the linkage system adjusts thepitch on the main blades to resist this change.

So the electronic components of the system take over these tasks from the flybarSo why ditch the flybar and change to a flybarless head setup?Flybarless helicopters have arguably better all round aerobatic performance. But they are also great forscale models, aerial photography platforms, etc
Advantages include:

Less rotating mass
Lower drag
Combination of longer flight time and better 3D performance
Less mechanical complexity
Infinitely tunable flight characteristics, including improved stability if desired
Looks cool!

What is required:

The Flybarless Head Itself It is ideal to purchase a custom designed flybarless head for your size of helicopter rather than try and modify an existing setup. There are several reasons for this:

The geometry of the head is important
You are purchasing a product that is known to work

Flybarless Electronics You require a system to take over the role of the flybar. There are two and three axis units on the market. For general flying a two axis unit (meaning you still require your own tail gyro) works very well. For 3D flying there are advantages of three axis units, however the two axis ones still hold their own.A two axis unit essentially contains two heading hold gyros (left/right and fore/aft cyclic). A three axis unit adds a tail rotor gyro also. Much like the way a traditional tail rotor heading hold gyro works, the cyclic gyros have the ability to stabilize the rotor head from wind gusts, etc.It is possible to fly a flybarless helicopter without electronic stabilization. However, the task is much easier with the help of an electronics package. You would not fly your helicopter without a tail gyro, would you?
Servo Selection Fast digital servos are preferable. But again, depending on your flying style,any reasonable servo will allow you to experience the flybarless feel.

In Flight: Flybarless helis can be set up to behave in an almost unlimited number of ways. With a flybar,it was time consuming (and expensive) to try a variety of flybar lengths, different paddles, and flybarweights. With the electronic flybar it is simply a matter of changing some of the programmableparameters in the unit itself and you have a whole new feel to the helicopter.There are some further flight differences with a flybarless heli. The cyclic controls now command acyclic rate from the rotor head. So if the helicopter is on the ground and even a small cyclic command isheld, the cyclic servos may move hard over to try and achieve the commanded cyclic rate. So it isimportant not to add cyclic control until the helicopter has lifted off.Autorotation performance is overall improved, but somewhat of a different technique is required torealize this increase in performance.

Do you like cool gadgets? Do you wish to buy some really funky gadgets of different types, which use the most modern technology? Some online wholesalers in China sell gadgets like watches, car DVD players, scanners, and key finders etc. which use modern technology. You can even buy a spy gear that you would not find anywhere else except with some online wholesalers. The gadgets are available in different price range, and cater to all age groups and genders.

One of the most fascinating electronics gadgets sold is the LED touch screen watch. This is a watch that uses the latest advancements in LED technology. You can change the time using the touch screen. The watch is usually all black with a green, shining circular outline. You have options to change not only the time, but also the color of the dial, the mode of timing (12 hour or 24 hour), choosing between analog and digital display etc. This is a Japanese inspired watch, which is much more lightweight than its original product. The watch has a unique look and it glows in the dark. It can be used in any terrain as long as you use the casing provided with it by the manufacturer.

One of the many unique electronics gadgets that wholesalers sell is a portable scanner. A scanner is a device used to store hard copy documents in digital form. The portable scanner offered by these wholesalers has the ability to scan any document at any time, while on the move. You can choose a high or standard resolution for scanning. Following this, all you have to do is move the scanner over an area and it quickly scans and saves images onto a micro SD card. This also enables easy retrieval.

Saturday nights are meant for partying and fun. However, if you drive under the influence of alcohol, you might be caught by the police. The police often use breathalyzers to assess if you have consumed alcohol. However, you can buy your own breathalyzer from the retail stores online. This way, you can check your own blood alcohol concentration before you decide to drive. These electronics gadgets come with an adapter and are stylishly built. It emits audio and visual signals to indicate an alcohol level above the permissible limit. The device can be adjusted to increase or reduce the level that sends out over-the-limit signals (since DUI laws differ in different states).

Would you like your kid to play with a unique toy car, which performs amazing stunts? Gadgets like stunt cars controlled by I-Pod, I-Phone or I-Pads are now available in the market. You merely have to download a controller application from an I-Tunes store online, and plug in the transmitter. Buying funky electronics gadgets from online wholesalers is much cheaper than buying it from retailers who charge exorbitant amounts. The wholesalers deliver to almost any country in the world, and provide a wide range of shipping options by air or sea.

Basic Laws Of Electronics

blogger April 28, 2023

Thanks to the physical laws of electronics, circuit analysis is very procedural. This is the second entry in a tutorial in basic electronics. The first entry covered basic electronic concepts such as voltage, current, and power. This session will cover Ohm’s Law, and Kirchhoff’s Laws of voltage and current. These are the fundamental laws needed for circuit analysis and design.

Resistors and Ohm’s Law
Georg Simon Ohm was a German physicist that in 1826 experimentally determined most basic laws that relate to voltage and current for a resistor.

Ohm’s law basically states that the resistance of a component (commonly a resistor) is equal to the voltage dropped over the resistor divided by the current going through it.

This law makes it relatively easy to find one of three values: voltage across a resistance, the resistance value itself, or the current flowing through the resistance (as long as the other two values are known).

Nodes, Branches, and Loops
These three concepts must be understood for basic circuit analysis. They help determine if components are in series or parallel and if the components share the same current or have the same voltage drops.

A branch represents a single circuit component such as a resistor or voltage source.

A node is a point where two or more branches connect.

A loop is any closed path in a circuit.

Elements are in series if they exclusively share a single node. Elements that are in series share the same current.

Elements are in parallel if they are connected to the same two nodes. Elements in parallel have the same voltage across them.

Kirchhoff’s Laws
The first of Kirchhoff’s Laws is Kirchhoff’s current law (KCL). This law states that the sum of all current entering a node or enclosed area of a circuit is equal to zero. Simply put, current entering a node or area equals the current leaving the node or area.

The second of Kirchhoff’s Laws is Kirchhoff’s voltage law (KVL). This law states that the sum of all voltages around a closed path or loop is equal to zero. Simply put, the sum of voltage drops equals the sum of voltage rises.

This is found by following the loop in one direction (the direction does not matter). If the positive terminal is hit first, the voltage is added. If the negative terminal is hit first, the voltage is subtracted. Together these values will equal zero.

Once all of the voltages are found, we can start the loop anywhere we want. I find it convenient to start at the negative terminal of a main voltage source. Since we hit a negative terminal first, we subtract it. Now we simply finish the loop and add the voltages together.

This law comes in very handy for analysis.

Basic DC Analysis
By combining Kirchhoff’s voltage and current laws, basic DC circuits are relatively easy to analyze. Knowing that all voltages in a loop add up to zero and all currents entering a node, minus currents leaving a node also equals zero, most current and voltage values can be easily obtained.

If a loop contains one voltage source and multiple resistances, voltage division (eq. 1) should be used to find the value of voltage drops across the known resistances. Once the voltage across the known resistance is found, Ohm’s law (eq. 2) can be used to determine the current flowing through the resistance.

Eq.1 Voltage Division:
((voltage source in volts) (resistor of interest in ohms))/(sum of resistance in loop)

Eq.2 Ohm’s Law:
(voltage across a resistance) = (known resistance)(current flowing through resistance)

Keep in mind that resistors in series can be added to give total resistance between two nodes. The total resistance between two nodes that have resistors in parallel is found using eq. 3 below.

Eq. 3 Equivalent Resistance (Req) of Resistors in parallel:
Req = ((resistance in branch 1)(resistance in branch 2)) / (sum of resistances in both branches)

There is much more to be said about DC circuit analysis but most would go beyond the scope of this article. The purpose of this article is to give a basic understanding of the laws and concepts of basic electronics.

Other concepts that make DC circuit analysis easier are current division, mesh analysis, and nodal analysis. These techniques use the rules behind KVL, KCL, and Ohm’s Law but would require a visual example for thorough explanation.

I hope that this short tutorial has been helpful to anyone who is new to the world of electronics either as a hobbyist or as a technician trying to learn electronics repair.
