How to Install Mac OS X Snow Leopard on a Windows PC

There are thousands of Computer Users who would always dream to own a Mac and this is not just for the beautiful looks or the powerful hardware but for the Operating System OS X which is one of the reason Apple is selling their products in large numbers. Now its quite possible for anyone to install a Mac OS X Snow Leopard the latest OS from Apple on their normal computers powered with Windows or Linux. Here are few of the reasons why you would be looking to perform this job.

• If you are planning to test the software applications available in the DMG format which don’t run in the Windows based computers. Normally you need to get a Mac for testing our all the software’s which are built for the OS X Based computers.
• If you plan to demonstrate the Mac applications to your students at school, college or office then without buying a iMac or McBook you can still use all the applications and perform all the educational homework.

You need to understand that Apple does not legally allow you to run a Windows based computer to run their Operating System and this is against their License Agreement, hence if you intend to perform this installation its recommended that you do it for Demo or Education Purpose only. If you like the Operating System or the Applications then its recommended that you go and buy a Mac instead of continuing running using this method.

In order to get started with this you need to first install a software that will create a virtual environment on your computer. There are many different options available here but we are going to install ‘VMware Workstation‘ which allows you to install multiple operating systems on a single computer reducing your hardware costs by more than 50% because you don’t have to buy different computers if you want to run different applications through multiple OS. If you are just testing out this process its recommended to download a trial version of this software and get started.

Once you install the VMware Workstation on your computer, you will find a new Tray Icon in your Taskbar which displays all the Virtual OS running on your computer. Next you need to import a pre-configured VMware file which would install Snow Leopard on the computer. Here is a link to download a copy of this file. Extract all the files using a File Extraction Software like Winzip or Winrar and open the same using the VMware Workstation software. A Iso file is extracted along with a lot of virtual disk files which can be installed on Intel Based Processors.

Browse and Open the MAC OS X Server file which had downloaded in the form of the ISO file and the following screen would appear.

Next you can configure the Devices option using the ‘Edit Virtual Machine Settings’ which will allow you to Increase or Decrease the Memory Size, Hard Disk Space, Processors, CD/DVD Drive, Display etc. Generally its recommended to increase the RAM size if its possible because that way you can run both the Operating Systems with better performance. Next under the CD/DVD Edit option you need to select the downloaded ISO file[Darwin_Snow.iso] instead of the ‘Auto detect’ option.

Next you need to ‘Power ON’ your Virtual Machine which will run the Snow Leopard OS on the Virtual Machine, but while this process starts you need to press the F8 button so that the Booting Options would be displayed on the screen.

Note : In my case i got a error message when i went for the Power ON option which said – ‘Mac OS X is not supported with software virtualization. To run Mac OS X you need a host on which VMware Player supports hardware virtualization.’ This means that your computer does not support virtualization and you need to perform this process on another computer with a Intel Process, but in my case i had a Core i7 Processor with 6Gb Ram, Hence in order to fix this i had to restart the Laptop and then under the BIOS settings Enable Virtualization as shown below.

The Snow Leopard Installation file would be downloaded in the form of a .DMG file which has to be converted into ISO File first. Next while the Mac is Booting up you need to click on the CD Settings and select the CD/DVD Disk Drive or Auto Select option as shown below to make the software to find the Snow Leopard Installation files from your computer.

Next you will be shown a option to select to Boot from DVD or else from HDD or Eject DVD, select the Boot from DVD option. You will get the Leopard Installation Screen before you which you need to proceed and completed. Make sure that you restart your computer a few times and also adjust the screen resolution for better quality display. Don’t forget that this tutorial has to be implemented only for testing or educational purpose only and not for commercial usage.

Make Windows XP Look like Apple Mac OS X Leopard with Transformation Pack

Last time i had written a article in which we had made Windows XP Look like Windows 7 which really worked perfect and gave the ultimate looks of a Windows 7 based computer and this time iam going to give you a link to such a application which would transform your total computer which would be Windows XP based and would look like as if you are running a Apple Mac OS X based computer.

Convert Windows Xp to Apple Mac OSX

The installation package would install all the required files automatically and after this a new Leopard-X visual style along with 4 different variations would appear ie
1. – Leopard-X visual style (4 variations)
2. – Leopard-X styler
3. – Leopard-X Mac search skin
4. – Leopard-X Dock skin
5. – Wallpapers

How to install:
To use this visual style you’ll need to patch your windows first. You need to download and install
Uxtheme Multi-patcher!
To do that follow next links:
For Windows XP – SP2:

http://www.softpedia.com/get/System/OS-Enhancements/UXTheme-MultiPatcher.shtml

For Windows XP – SP3:

http://www.softpedia.com/get/System/OS-Enhancements/SP3-UxTheme-Patcher.shtml

Upon successful installation, just unpack and install Leopard-X visual style!
Open Display properties/Appearance, and switch on Leopard-X visual style.
Then click Apply and this is it!

Full Screenshot Below :

Apple Leopard OSX

Tips and tricks:
To make that window looks same as it is here presented in this promo pictures you’ll need to do the next: Activate status bar in explorer (explorer menu: view/status bar) and check it “on”!

Status Bar

The bottom status bar will appears. Then open display properties, switch on Appearance and from Color
scheme choose: Aqua or Graphite variation!

Windows Display Properties

Aqua & Graphite light variations are built with the thinner frame which means that they don’t support rounded edges in the status bar. This is recommended variation if you do not use status bar! If you do, like here in this example, well then just use Aqua or Graphite color variation. Download and install Styler.

Styler Toolbar

After installation you’ll need to activate Styler, and you can do that by calling the menu from the window.
Just click near the help menu with the right button and choose from menu StylerToolBar… The rest
should be unchecked (or hidden).

Leopard Styler

Then open Styler menu and from there hide menu in explorer! You can also enable windows shadow effect from there. Just check Desktop tab. This is what you should get at the end! Install XWindows Dock for full Leopard experience and even more.

It can do next things:
1. Real-time dock icons reflection
2. Real-time windows reflection
3. Applied dock icons shadow effect
4. Applied blur reflection effect
5. Icons positioning inside the dock
6. Stack video preview
7. Picture folder gallery preview
8. Advanced stack animations, and more…
And what is most important, user can manipulate and set all these elements separately

Get Mac OS X Snow Leopard Taskbar Dock in Windows PC

The Taskbar Dock which comes up in the Apple Mac OS X Operating Systems is seriously very much beautiful and also intelligent because it does not just offer you with a nice taskbar but also offers you with features which can be useful in the daily life. The Dock is not available in the Windows based computers because the windows pc users get a flat taskbar with a start button and application shortcuts in the left and a clock and few icons on the right side. Its now possible to have a Dock in Windows Computers using the RK Launcher Application which can be downloaded from here.

Once you download the file, it comes in the form of a zip format which is a compressed state and you need to extra all the files within the downloaded zip using a freeware like Winzip or Winrar. Next a bunch of files and folders would appear in the Extracted section which would help the software to run. Click on the RKLauncher.exe file which will start the application.

The Dock looks awesome but again is displayed over your normal Taskbar Icons which can create a problem because you cannot click on the icons already listed in the Windows Taskbar and they can be accessed only when you press ‘Alt+Tab’ keys. Next we need to configure the Dock and move it to the left or right side of the screen where it can get its own screen area. The third last option from the right is the ‘Control Panel’ shortcut of your computer.

Features :

• When you mouse over the Taskbar Dock the Icons automatically zoom in and you will find that the size increases, giving you a better viewing of the shortcuts and easy way to access and run them. While if you move the mouse away from this, they will be resized to the normal size as shown above.
• Once you minimize any application it will be automatically displayed in the Taskbar Dock, under the shortcuts bar with a small thumbnail image of the contents of the running program.
• If you install a new software, whenever you run it for the first time, a shortcut for the same is generated and displayed in the Taskbar Dock, making it very simple and easy for you to access the same.

Overall a recommended nice software for PC lovers who love the MAC OS Looks. If you are looking for a complete overhaul of your PC and Make Windows XP Look like Apple Mac OS X, check out the transformation pack or else read our tutorial on Installing Mac OS X Snow Leopard on a Windows PC.

Make Windows XP Look like Windows 7 with Transformation Pack

I have been using Windows XP and liked it so much that i didnt even bother to move to Windows Vista when it was launched and since the Laptop came Preinstalled with a Licensed Copy of Windows XP, there was no point of moving to other OS. Now when Windows 7 is around i thought to either buy a new Copy or else get a Look which looks similar to Windows 7, which is when i tried of Windows 7 Transformation Pack specifically for Windows XP computers.

Convert Windows XP Windows7

The Seven Remix XP is a full installer which has a complete collection of files, icons, images and animations which are a part of Windows 7 Operating System. This is a transformation pack which means that you are going to change the way how stuff looks in Windows XP but not the way it works because you can feel you are in Windows 7. The installer automates the process of substitution of system files. It applies adjustments in the registry, it installs programs of third, skins and visual extras like sounds, styles, etc. In addition, it makes a backup of its archives in case that it needs to recover them. It is enough with executing the desinstallation from the menu Beginning or Adding or clearing programs.

Make Windows Look like Windows 8 with Transformation Pack

We had previously written a tutorial on how to make your Windows XP look like Windows7, and this time you will be able to install the Windows 8 Transformation Pack to make your computer look more advanced with the advanced graphics and styles for getting the looks of Windows 8 Professional Edition. The current build is not available for Windows 7 or Windows xp users but Vista X86 or X64, SP0, SP1, SP2 users can easily install this.

Before you install any of these transformation tools make sure that you create a Restore Point using the System Restore option because if there is something which goes wrong you may loose your OS because of many errors, hence the restore function can save up everything. The transformation pack is going to change the following :

* Windows Theme or Visual Style
* Login Screen or Welcome Screen
* Taskbar
* Taskbar clock, System try icon & Quick Launch
* Wallpapers
* About Windows Box
* System Properties
* Extra

Desktop Screenshot :

The new looks of Windows 8 would actually change the taskbar, start menu, Windows Explorer, a different concept login screen ie changes made in background image and text displayed at bottom.

The Taskbar now called as Superbar looks quite similar to Windows 8, by showing the Icons in a row instead of the normal way of showing the Active Running Programs name in the taskbar buttons. While you mouse over this you will get a quick preview of the running programs, bit similar to the Mac OS X Taskbar Dock.

How to Jailbreak Apple iPhone 3.1.3 – Tutorial & Tips

The first and foremost thing you need to do is check out if the device you are planning to jailbreak can be succeeded or not. This is because many times users start with the jailbreaking and unlocking of their devices without checking out if its really possible or not. Hence prior checking is very important where in you can use these quick tools and then proceed towards the jailbreaking process. This tutorial would be useful for users who have earlier Jailbroken their iPhone 2G/3G/3GS 3.0/3.1.2 with redsn0w, Quickpwn, Ultrasn0w, PwnageTool & Blackra1n.

To get started you need to first download the correct ipsw file from Apple Firmware Downloads and save it on your Desktop. The next step would be downloading the Sn0wBreeze tool from this website and saving a copy of the file on your desktop. This procedure is for Windows users who have Windows XP, Vista, 7 (32 or 64bit) Operating System.

Now to get started read the following steps and perform them one by one carefully.

• Create a Folder on your Desktop with any Name and move both the Sn0wBreeze file & the Firmware .ipsw file in that.
• Next you will have to run the sn0wbreeze-V.exe file and then proceed towards the installation process.
• The application would ask you to select any of the two modes ie Simple & Expert out of which its recommended to proceed with the Simple mode because in that case everything is done automatically with easy wizard based setup and you wont have to worry about configurations. Best for first times because this way the tool will automatically download all the applications.
  
• Click on the Blue Arrow to continue, and you will be asked to select the firmware file which you had earlier downloaded to your desktop folder. Browse and select this file which the sn0wbreeze application would detect and then proceed ahead towards Jailbreak.
  
• Next the software will install Cydia, ipsw files etc and will create a new IPSW file which is a new modified version you need to install, following which at the end you will be shown with a message which says ‘Done! sn0wbreeze seems to have sucessfully created your ispw, this file will be located on your Desktop. You will be asked if the device is already Jailbroken or not. If you are sure about this then proceed with Yes or else select No/Not Sure option which will manage everything.
  
• Next you will be asked to Connect your iPhone, and Enter Recovery Mode. After that, Launch iTunes and Hold down SHIFT while clicking the RESTORE button in iTunes. To get into the DFU Mode, Connect your device, Turn it off and click start when you are ready. Once the device is shut down, you will be asked to Press the Power & Home button both at once for 10 seconds, next you need to leave the Power Button and continue pressing the home button for next button following which the device will enter the DFU Mode. Once this is done you will find a Success Message for the same.
  
• Now you will be asked to Restore the iPhone using the iTunes Application. When you run the iTunes you will get a message which says ‘iPhone is in Recovery Mode you need to restore it’ as shown below.
  
• Now we will have to Restore the Modified ipsw file which was created and saved on the desktop. You will have to press Shift button and click on the ‘Restore’ button in iTunes. Next you will be asked to select the file, which you can browse and select from the desktop. Once you have selected the iTunes will Prepare the iPhone to be restored. This task would include extracting, testing and repair of your iPhone following which its completed and your device is back.
  
• Note : When we were trying this Restoring option at the end, were we getting the 1601 / 1602 Apple error which needs you to reinstall all the softwares like iTunes on your computer and then try to restart the procedure. We went ahead starting the iPhone and then restoring the device from the iTunes when the device was running normally. This made the device to automatically restart and then all the data was slowly transferred, finally restoring all the files and previous information.
  
  
  
  

Enjoy the Jailbroken updated iPhone Device!

How to use a Multi-tester (Analog)

Step by step Cellphone repair tutorial - Basic to Advance - Topic 03

A multimeter is an instrument used to check for AC or DC voltages, resistance or continuity of electrical components and small amounts of current in circuits. This instrument will let you check to see if there is voltage present on a circuit, etc. This article will discuss analog meters.

What is a multitester: A multitester is a tool that can be use to check resistance, continuity, and voltage in electrical components.

These meters come in digital or analog. Analogs been the cheaper in price and the digitals been the more accurate.

Why do I need a multitester: Most of the washer or dryer switches are seal and you won't be able to see inside, so the only way to know if the contacts are close or open is with a multitester.

How I check resistance or continuity: To check for resistance or continuity you will need to set the multitester to red ohms. You will check for resistance in a heating elements, motor windings, and solenoids. You will check for continuity on switches, thermostats, thermal fuses, house fuses, etc.

How I check for voltage: To check for for voltage you need to set the multitester in to AC volts. My multitester has 3 settings 15 volts, 150 volts, and 1000 volts.

Why I do need different scales: If you are checking an appliance that runs on 120 volts, then you can use the 150 scale. If you are checking an electric dryer that use 240 volts for the heating element, then you need to move the scale to higher that the voltage you are reading, in this case you need to set it to 1000 volts.

Become Familiar With the Parts of a Multimeter. Inspect the meter. Starting from the top and working to the bottom:

• The dial. This has the arc shaped scales visible through the window. The pointer indicates values read from the scale.
• The pointer or needle, this is the thin black line at the left-most position in the dial face window in the image. The needle moves to the value measured.
• Arc shaped lines or scales on the meter dial face. May be different colors for each scale but will have different values. These determine the ranges of magnitude.
• A wider mirror like surface shaped like the scales mentioned previously might also be present. The mirror is used to help reduce parallax viewing error by lining up the pointer with its reflection before reading the value the pointer is indicating. In the image, it appears as a wide gray strip between the red and black scales.
• A selector switch or knob. This allows changing the function (volts, ohms, amps) and scale (x1, x10, etc.) of the meter. Many functions have multiple ranges. It is important to have both set correctly, otherwise serious damage to the meter or harm to the operator may result. Most meters employ the knob type like the one shown in the image, but there are others. Regardless of the type, they work similarly. Some meters (like the one in the image above) have an "Off" position on this selector switch while others have a separate switch to turn the meter off. The meter should be set to off when stored.
• Jacks or openings in the case to insert test leads. Most multimeters have several jacks. The one pictured has just two. One is usually labeled "COM" or (-) for common and negative. This is where the black test lead is connected. It will be used for nearly every measurement taken. The other jack(s) is labeled "V (+) and the Omega symbol" (an upside down horseshoe) for Volts and Ohms respectively and positive. The + and - symbols represent the polarity of probes when set for and testing DC volts. If the test leads were installed as suggested, the red lead would be positive as compared to the black test lead. This is nice to know when the circuit under test isn't labeled + or -, as is usually the case. Many meters have additional jacks that are required for current or high voltage tests. It is equally important to have the test leads connected to the proper jacks as it is to have the selector switch range and test type (volts, amps, ohms) set. All must be correct. Consult the meter manual if unsure which jacks should be used.
• Test leads. There should be (2) test leads or probes. Generally, one is black and the other red.
• Battery and fuse compartment. Usually found on the reverse, but sometimes on the side. This holds the fuse (and possibly a spare) and the battery that supplies power to the meter for resistance tests. The meter may have more than one battery and they may be of different sizes. A fuse is provided to help protect the meter movement. Sometimes there is more than one fuse. A good fuse is required for the meter to function. Fully charged batteries will be required for resistance / continuity tests.
• Zero Adjustment. This is a small knob usually located near the dial that is labeled "Ohms Adjust", "0 Adj", or similar. This is used only in the ohms or resistance range while the probes are shorted together (touching each other). Rotate the knob slowly to move the needle as close to the 0 position on the Ohms scale as possible. If new batteries are installed, this should be easy to do - a needle that will not go to zero indicates weak batteries that should be replaced.

Use the Ohm Function to Measure Resistance

1. Set the multimeter to Ohms or Resistance (turn meter on if it has a separate power switch). Understand that resistance and continuity are opposites. The multimeter measures resistance in ohms, it can not measure continuity. When there is little resistance there is a great deal of continuity. Conversely, when there is a great deal of resistance, there is little continuity. With this in mind, when we measure resistance we can make assumptions about continuity based on the resistance values measured. Observe the meter indication. If the test leads are not in contact with anything, the needle or pointer of an analog meter will be resting at the left most position. This is represents an infinite amount of resistance, or an "open circuit"; it is also safe to say there is the no continuity, or path between the black and red probes. Careful inspection of the dial should reveal the OHM scale. It is usually the top-most scale and has values that are highest on the left of the dial (a sideways "8" for infinity) and gradually reduce to 0 on the right. This is opposite of the other scales; they have the lowest values on the left and increase going right.
2. Connect the black test lead to the jack marked "Common" or "-"
3. Connect the red test lead to the jack marked with the Omega (Ohm symbol) or letter "R" near it.
4. Set the range (if provided) to R x 100.
5. Hold the probes at the end of the test leads together. The meter pointer should move fully to the right. Locate the "Zero Adjust" knob and rotate so that the the meter indicates "0" (or as close to "0" as possible). Note that this position is the "short circuit" or "zero ohms" indication for this R x 1 range of this meter. Always remember to "zero" the meter immediately after changing resistance ranges.
6. Replace batteries if needed. If unable to obtain a zero ohm indication, this may mean the batteries are weak and should be replaced. Retry the zeroing step above again with fresh batteries.
7. Measure resistance of something like a known-good lightbulb. Locate the two electrical contact points of the bulb. They will be the threaded base and the center of the bottom of the base. Have a helper hold the bulb by the glass only. Press the black probe against the threaded base and the red probe against the center tab on the bottom of the base. Watch the needle move from resting at the left and move quickly to 0 on the right.
8. Change the range of the meter to R x 1. Zero the meter again for this range. Repeat the step above. Observe how the meter did not go as far to the right as before. The scale of resistance has been changed so that each number on the R scale can be read directly. In the previous step, each number represented a value that was 100 times greater. Thus, 150 really was 15,000 before. Now, 150 is just 150. Had the R x 10 scale been selected, 150 would have been 1,500. The scale selected is very important for accurate measurements. With this understanding, study the R scale. It is not linear like the other scales. Values at the left side are harder to accurately read than those on the right. Trying to read 5 ohms on the meter while in the R x 100 range would look like 0. It would be much easier at the R x 1 scale instead. This is why when testing resistance, adjust the range so that the readings may be taken from the middle rather than the extreme left or right sides.
9. Test resistance between hands. Set the meter to the highest R x value possible. Zero the meter. Loosely hold a probe in each hand and read the meter. Squeeze both probes tightly. Notice the resistance is reduced. Let go of the probes and wet your hands. Hold the probes again. Notice that the resistance is lower still. For these reasons, it is very important that the probes not touch anything other than the device under test. A device that has burned out will not show "open" on the meter when testing if your fingers provide an alternate path around the device, like when they are touching the probes. Testing round cartridge type and older style glass automotive fuses will indicate low values of resistance if the fuse is lying on a metal surface when under test. The meter indicates the resistance of the metal surface that the fuse is resting upon (providing an alternate path between the red and black probe around the fuse) instead of trying to determine resistance through the fuse. Every fuse, good or bad, will indicate "good".
   

Use the Volts Function to Measure Voltage

1. Set the meter for the highest range provided for AC Volts. Many times, the voltage to be measured has a value that is unknown. For this reason, the highest range possible is selected so that the meter circuitry and movement will not be damaged by voltage greater than expected. If the meter were set to the 50 volt range and a common U.S. electrical outlet were to be tested, the 120 volts present could irreparably damage the meter. Start high, and work downward to the lowest range that can be safely displayed.
2. Insert the black probe in the "COM" or "-" jack.
3. Insert the red probe in the "V" or "+" jack.
4. Locate the Voltage scales. There may be several Volt scales with different maximum values. The range chosen the selector knob determines which voltage scale to read. The maximum value scale should coincide with selector knob ranges. The voltage scales, unlike the Ohm scales, are linear. The scale is accurate anywhere along its length. It will of course be much easier accurately reading 24 volts on a 50 volt scale than on a 250 volt scale, where it might look like it is anywhere between 20 and 30 volts.
5. Test a common electrical outlet. In the U.S. you might expect 120 volts or even 240 volts. In other places, 240 or 380 volts might be expected. Press the black probe into one of the straight slots. It should be possible to let go of the black probe, as the contacts behind the face of the outlet should grip the probe, much like it does when a plug is inserted. Insert the red probe into the other straight slot. The meter should indicate a voltage very close to 120 or 240 volts (depending on type outlet tested). Remove the probes, and rotate the selector knob to the lowest range offered, that is greater than the voltage indicated (120 or 240). Reinsert the probes again as described earlier. The meter may indicate between 110 and as much as 125 volts this time. The range of the meter is important to obtain accurate measurements. If the pointer did not move, it is likely that DC was chosen instead of AC. The AC and DC modes are not compatible. The correct mode MUST be set. If not set correctly, the user would mistakenly believe there was no voltage present. This could be deadly. Be sure to try BOTH modes if the pointer does not move. Set meter to AC volts mode, and try again. Whenever possible, try to connect at least one probe in such a way that it will not be required to hold both while making tests. Some meters have accessories that include alligator clips or other types of clamps that will assist doing this. Minimizing your contact with electrical circuits drastically reduces that chances of sustaining burns or injury.

Use the Amps Function to Measure Amperes

1. Determine if AC or DC by measuring the voltage of the circuit as outlined above.
2. Set the meter to the highest AC or DC Amp range supported. If the circuit to be tested is AC but the meter will only measure DC amps (or vice-versa), stop. The meter must be able to measure the same mode (AC or DC) Amps as the voltage in the circuit, otherwise it will indicate 0.
   Be aware that most multimeters will only measure extremely small amounts of current, in the uA and mA ranges. 1 uA is .000001 amp and 1 mA is .001 amp. These are values of current that flow only in the most delicate electronic circuits, and are literally thousand (and even smillions) of times smaller than values seen in the home and automotive circuits that most homeowners would be interested testing. Just for reference, a typical 100W / 120V light bulb will draw .833 Amps. This amount of current would likely damage the meter beyond repair. A "clamp-on" type ammeter would be ideal for the typical homeowner requirements, and does not require opening the circuit to take measurements (see below). If this meter were to be used to measure current through a 4700 ohm resistor across 9 Volts DC, it would be done as outlined below:
3. Insert the black probe into the "COM" or "-" jack.
4. Insert the red probe into the "A" jack.
5. Shut off power to the circuit.
6. Open the portion of the circuit that is to be tested (one lead or the other of the resistor). Insert the meter in series with the circuit such that it completes the circuit. An ammeter is placed IN SERIES with the circuit to measure current. It cannot be placed "across" the circuit the way a voltmeter is used (otherwise the meter will probably be damaged). Polarity must be observed. Current flows from the positive side to the negative side. Set the range of current to the highest value.
7. Apply power and adjust range of meter downward to allow accurate reading of pointer on the dial. Do not exceed the range of the meter, otherwise it may be damaged. A reading of about 2 milliamps should be indicated since from Ohm's law I = V / R = (9 volts)/(4700 Ω) = .00191 amps = 1.91 mA.
8. If you're measuring the current consumed by the device itself, be aware of any filter capacitors or any element that requires an inrush (surge) current when switched on. Even if the operating current is low and within the range of the meter fuse, the surge can be MANY times higher than the operating current (as the empty filter capacitors are almost like a short circuit). Blowing the meter fuse is almost certain if the DUT's (device under test) inrush current is many times higher than the fuses rating. In any case, always use the higher range measurement protected by the higher fuse rating (if your meter has two fuses), or just be careful.

Tips

• When you are going to check any part for continuity, you must remove the power. Ohm meters supply their own power from an internal battery. Leaving power on while testing resistance will damage the meter.

Warnings

* Always check meters on known good voltage sources to verify operational status before using. A broken meter testing for volts will indicate 0 volts, regardless of the amount present.
* Never connect the meter across a battery or voltage source if it is set to measure current (amps). This is a common way to blow up a meter.
* Respect electricity. If you don't know something, ask questions and research the subject.

Step by step Cellphone repair tutorial - Basic to Advance - Topic 03

Opening Tools
Cell phone tools essential for phone maintenance and repairs, screwdrivers, phone opening tool kits, screw drivers packs and Tweezers.




Tweezers are tools used for picking up and manipulating objects too small to be easily handled with the human hands.Its very useful in surface mounted electronics components.



Precision Screwdrivers

Do not try to attempt opening any screws that did not match with the screwdriver you have or you might end up a loosen tread screw, and find it hard enough to open it up...
Selecting and collecting of precision screwdrivers is highly recommended.
Torx and Precision comes with different code and number..
T6 is the most commonly used in mobile phones especially Nokia Mobiles Phones.

View and Retrieve or Change Windows (XP, Vista, 2003, 2000 and more) and Office (XP, 2003, 92) Product Key or CD Key

he Windows computer may come preinstalled with Microsoft Windows operating system and Microsoft Office productivity suite, and the user may not even see or access to the product key or CD key that needed to install Windows OS and Office System, and to make sure that the products are genuine. You may simply want to write down and safekeep the Windows and/or Office product CD key or serial number for future usage or for documentation purpose, as the key is as good as license to use Windows and Office. Or you want to get back the CD key that has been forgotten before reinstalling Windows or Office. There are a few tools and utilities that allows you to easily and quickly retrieve the Windows product key and Office CD key or serial number. Some of them has the ability to change the serial key too, in case you need to modify the product key in Windows due to case like 326904 error “The Product Key Used to Install Windows Is Invalid” or incorrect product license key.

How to Speed Up your Firefox web Browser

Mozilla Firefox is a graphical web browser developed by the Mozilla Corporation. Started as a fork of the browser component (Navigator) of the Mozilla Application Suite, Firefox has replaced the Mozilla Suite as the flagship product of the Mozilla project, stewarded by the Mozilla Foundation and a large community of external contributors.

Mozilla Firefox is a cross-platform browser, providing support for various versions of Microsoft Windows, Mac OS X, and Linux. Although not officially released for certain operating systems, the freely available source code works for many other operating systems, including FreeBSD,OS/2, Solaris, SkyOS, BeOS and more recently, Windows XP Professional x64 Edition.

I am providing some Very Useful Tips to speedup your Firefox.

In your location bar, type about:config
Once it Opens You should see similar to the following screen

Tweak 1
In the filter bar type network.http.pipelining
You should see the following screen


Normally it says ” false ” under value field , Double click it so it becomes ” true “.
Once you finished this you should see the following screen.

Tweak 2
In the filter bar again and type network.http.pipelining.maxrequests
Once it Opens You should see the following screen


Default it says 4 under value field and you need to change it to 8
Once you finished this you should see the following screen.

Tip3
Go to the filter bar again and type network.http.proxy.pipelining
Once it Opens You should see similar to the following screen


Normally it says ” false ” under value field , Double click it so it becomes ” true “.
Once you finished this you should see the following screen.

Tweak 4
Go to the filter bar again and type network.dns.disableIPv6
Once it Opens You should see the following screen

Normally it says ” false ” under value field , Double click it so it becomes ” true “.
Once you finished this you should see the following screen.

Tweak 5
Go to the filter bar again and type plugin.expose_full_path
Once it Opens You should see the following screen

Normally it says ” false ” under value field , Double click it so it becomes ” true “.
Once you finished this you should see the following screen.

Tweak 6
Now you need to Create new Preference name with interger value for this got to Right click -> New -> Integer

Once it opens you should see the following screen

Here you need to type ui.submenuDelay and click ok

Now you need to enter 0 in value filed and click ok.

Once you finished this you should see the following screen.

Some more Tweaks

Enable the spellchecker for inputfields and textareas (default is textareas only)

layout.spellcheckDefault=2
Open lastfm://-links directly in amarok
network.protocol-handler.app.lastfm=amarok
network.protocol-handler.external.lastfm=true

Firefox Memory Leak Fix

Open a new tab. Type “about:config” without quotes into the address bar and hit enter/click Go.
Right-click anywhere, select New, then Integer. In the dialog prompt that appears, type:

browser.cache.memory.capacity

Click OK. Another dialog prompt will appear. This is where you decide how much memory to allocate to Firefox. This depends on how much RAM your computer has, but generally you don’t want to allocate too little (under 8MB), but if you allocate too much, you might as well not do this. A good recommended setting is 16MB. If you want 16MB, enter this value into the dialog prompt:

16384

(Why 16384 instead of 16000? Because computers use base-12 counting. Thus 16 megabytes = 16384 bytes. Likewise, if you want to double that and allocate 32MB, you’d enter 32768.)

Click OK to close the dialog box, then close all instances of Firefox and restart. If your Firefox still uses the same amount of memory, give it a few minutes and it should slowly clear up. If that fails, try a system reboot.

Now your Firefox will now be 3 – 30 times faster in loading pages.
