ELECTRONIC BASICS
Persons new to electronics can have difficulties with the component values and
descriptions. Here are some guidelines for resolving these problems.
a) Basics
b) Resistors
c) Capacitors
d) Diodes
e)Transistors
f) IC's
Basics
The most often used terms in electronics are voltage and current
To give you a metaphor for this you can think of a river.
The voltage is the length of the river and the current can be seen the current of the river.
This current is due the difference in height between the start and end of the river.
One law you have to remember is law of Ohm. (See OHM’S LAW). It is a simple law.
Voltage = Current * Resistance
or U = I * R
Where voltage is in voltage [V], current in Ampere [A] and the resistance in
Ohm.
To make it easier for you to make conversions I will provide you [literally] a
rule of thumb.
Voltage [V]
-------------------------------
Current [i] * Resistance [Ohm]
Now just place your thumb over the unknown value and you will see what you have to do to find the value. For example. If you want the know the resistance then
you have to divide the voltage by the current.
Numbers can become quiet large in electronics. To prevent writing many zero's
they use often different names. The following names are used.
Value, milli-, micro-, nano- and pico-
Example: Farad [capacitor] Farad, milli Farad [mF], micro Farad [uF], nano Farad
[nF], pico Farad [pF]
Every step is 1000 smaller like 1 Kg is 1000 Grams.
Resistors
Symbol
---/\/\/\/\----
or
------
---| |-----
------
A resistor can be seen as a dam in a river. Water will have more difficulties to
pass this dam. In a resistor this will result in the generation of heat.
Resistors come in standard values to choose from. The value of a resistor can be
found with the help of a colour table. The resistor has a set of coloured rings
that will tell you its value.
First ring : First number
Second ring : Second number
Third ring : Number of zeros to add
Fourth ring : Tolerance [quality of the resistor. Mostly 5%]
1 Brown Examples:
2 Red 4700 Ohm 1 000 000 Ohm
3 Orange Yellow Purple Red Brown Black Green
4 Yellow
5 Green
6 Blue
7 Purple Brown Black Brown Red Red Red
8 Grey 100 Ohm 2200 Ohm
9 'White'
0 Black
Values are often written as 10K, 1M or 4K7. This means in this case 10.000,
1.000.000 and 4700 Ohm. The 'K' just stands for Kilo and tells you that there is
a factor 1000 there. The 'M' stands for mega and adds another factor 1000
Capacitors
\
Symbol
||
---||---
||
A capacitor can have more functions but one of them is to store some energy in
them. They act like a bucket. You can fill them with energy and drop the
contents back when you need it.
Values are often written as 10N or 2N2. This means in this case 10.000 and 2200
nano Farad. The 'N' just stands for nano. Small capacitors can have only numbers
on them like 104. The first two digits is a number and the third digit tells you
how many zeros you must add. In this case its four. The correct value of this
component is 100 000 pF. [note: 100 nF or 0.1uF is also correct]
Diode
Symbol
|\ |
___| \|___
| /|
|/ |
Diodes are the passive one-way locks in the river. Water can flow through them
only in one direction. And only when there is enough difference in height
[voltage].
Knowing this you may notice that a diode needs to have a direction to function.
To show this there is a small mark at the casing. Normally this is a ring. For
LED this isn't the case. You have to look inside and see the small plates. The
one with the largest plate is the side where the 'ring' would be.
Transistor
Symbol
| /c c = collector
___|/ b = basis
b |\ e = emitter
| \e
These are the active locks in the river. They have a lock gate that can control
the flow through them. They can also act like a switch. With a little current
they can be opened and let a strong current pass. In the symbol there is also a
arrow that will tell you the direction of flow. There are two basic transistor
types namely; PNP and NPN. They are named todifferentiate between different internal designs. A PNP has a symbol with the arrow pointing inwards and a NPN
transistor has a arrow pointing outwards.
IC (Intergrated Circuit)
Symbol
An IC doesn't have a universal symbol.
It all depends on its use. A few
examples are shown here.
|\ +---+
___| \___ -| & |
| / -| |-
|/ +---+
A little box that contains many small components as above. A complete circuit
can be inside the black plastic casing.
They have often 8, 14 or 16 pins.
They are used for many purposes. The casing has a small notch on top of it or carved out of it.
If you look at this mark and holding the mark on top then the first
lead on the right side will be pin number one.

topic 2. Soldering Techniques
How important is soldering?
Among the foremost of reasons an electronic project frequently fails to work
properly is due to "poor" soldering practices. This is usually caused by "dry
joints" when soldering. Here we discuss the correct procedures for soldering
electronic projects.
Dry joints when soldering
At first glance many solder joints appear to be quite "O.K." but on closer
examination many are in fact defective. The insidious problem with dry joints in
soldering is that the circuit frequently performs alright for a period of time,
even years before failure.
This problem even occurs with manufactured equipment. Ask any TV / Video repair/Cell Phone technician who has torn a lot of hair out over an elusive fault ultimately traced back to a dry joint.
Good soldering practices for your electronic project
The cause of dry joints in soldering is mostly the improper application of heat.
Both the component leg and the PCB need to be both heated simultaneously to the
correct temperature to allow the solder to flow freely between BOTH surfaces.
Obviously this requires practice and most newcomers inevitably get it wrong.
Improper heating while soldering and its consequences can be seen below.
Figure 1 - correct soldering procedures to avoid dry joints
Here in figure 1 entitled "correct soldering procedures to avoid dry joints" we
have three examples of soldering depicted.
The first example indicates the component lead was heated while the PCB wasn't heated.As a consequence the solder only flowed onto the component lead.
In the second example of soldering in figure 1 we find the PCB was correctly
heated while little or inadequate heat was applied to the component lead. This
is the most treachorous example because although I have made it very obvious in
the diagram, in practice it is not always particularly obvious.
Often this type of dry joint "just" allows the solder to "touch" the component lead while not actually being "soldered" to the lead. Of course it might work for a period of time depending upon environmental conditions of heat and cold.
In the final example of "correct soldering procedures to avoid dry joints" We
have depicted the solder bridging both the PCB and the component lead.
In this case the PCB and the component lead were both heated "simultaneously" AND the solder was applied to either the component lead or the PCB to "flow" freely from one to the other to provide a good "electrical" joint. Such a joint is always "bright and shiny", dull looking joints are often suspect.
You never apply the solder to the soldering iron "tip". Solder is always applied
to the "job", never the soldering iron. Allow the solder to "set" and cool
before proceeding to the next joint.
Other cases of soldering
We have discussed soldering components to a PCB yet this is not the only case of
soldering. Often we need to connect wires to switches and other components. A
common misconception is that soldering is designed to provide a good mechanical
joint. - It isn't!
Any connection should have it's own mechanical strength perhaps by twisting
wires together or twisting the wire around a binding post or through a hole
provided for the purpose.
The solder is only intended for a good "electrical" connection. Never provide a connection which can't stand mechanically on it's own merits.
What's soldering flux?
Modern quality electronics solders contain a "flux" resin within the solder.
This flux is designed to flow over the job and prevent contact with the
atmosphere.
Metals, particularly copper when heated tend to "oxidise" and prevent the alloying or good electrical bond between the copper and the solder.
Good solder containing the resin will have resin flowing over the leads and
prevent this oxidisation process and as the solder flows the resin is displaced
allowing the solder to form an "atomic" bonding with the items being soldered
together. A good resin helps to keep the surfaces clean.
Rules for good soldering
Of course some of these rules might seem very obvious but are worth repeating.
=> Use a reasonable quality iron of the correct wattage for the job.
=> Only use "electronic" resin cored solder of fine gauge.
=> Make sure all surfaces to be soldered are "bright, shiny" and thoroughly
clean.
=> If a mechanical joint, make sure it can "stand alone" before soldering.
=> Make sure the solder tip is clean, shiny and properly "wetted".
=>Remember the soldering iron tip is only to heat up the surfaces to be
soldered.
=> Apply the resin cored solder to the heated "job", not to the soldering iron
tip.
=>Remember to visually inspect ALL of your soldered joints, preferably with
magnifying glasses.
=> Consider using your multimeter to provide an "electrical continuity" check
between various parts of the circuit.
Why is ohms law so very important?
Ohms law, sometimes more correctly called Ohm's Law, named after Mr. Georg Ohm, mathematician and physicist b. 1789 d. 1854 - Bavaria, defines the relationship between power, voltage, current and resistance. These are the very basic electrical units we work with. The principles apply to a.c., d.c. or r.f. (radio
frequency).
Ohms Law is the a foundation stone of electronics and electricity.
These formulae are very easy to learn and are used extensively throughout our
tutorials.
Without a thorough understanding of "ohms law" you will not get very
far either in design or in troubleshooting even the simplest of electronic or
electrical circuits.
Mr. Ohm (that is his 'real'name) [Georg Ohm b 1789 d 1854 - Bavaria] established
in the late 1820's that if a voltage [later found to be either A.C., D.C. or
R.F.] was applied to a resistance then "current would flow and then power would
be consumed".
Some practical every day examples of this very basic rule are:
Radiators (electric fires), Electric Frypans, Toasters, Irons and electric light
bulbs.
Figure 1 - ohms law power consumption through a resistance.
The radiator consumes power producing heat for warmth, the frypan consumes power producing heat for general cooking, the toaster consumes power producing heat for toasting bread, the iron consumes power producing heat for ironing our
clothes, and the electric light bulb consumes power producing heat and more
important light for lighting up an area.
A further example is an electric hot water system. All are examples of ohms law at its most basic.
Hot and Cold Resistance encountered in Ohms Law.
One VERY important point to observe with ohms law in dealing with some of these
examples is that quite often there are two types of resistance values.
"Cold Resistance" as would be measured by an ohm-meter or digital multimeter and a "Hot Resistance". The latter phenomenon is an inherent characteristic of the type of material used as a resistor. It has a temperature co-efficient which often once heated alters the initial resistance value, usually dramatically upward.
A very good working example of this is an electric light bulb.
Measure the light bulb with a digital multimeter. It will show zero
resistance, in fact open circuit.
Again, using a light bulb marked "240V - 60W".
It measured an initial "cold resistance" of 73.2 ohms. Then I measured our actual voltage at a power point as being 243.9V A.C. at that moment [note: voltages vary widely during a day due to locations and loads - remember that fact - also for pure resistances, the principles apply equally to A.C. or D.C.].
Using the formula which you will learn below, the resistance for power consumed
should be R = E2 / P OR R = 243.92 / 60W = 991 ohms .
That is 991 ohms calculated compared to an initial reading of 73.2 ohms with a
digital multimeter.
The reason?
The "hot" resistance is always at least ten times the "cold" resistance.
Another example is what is most often the biggest consumer of power in the
average home. The "electric kettle".
Take an “Electric Kettle " which is labelled "230 - 240V 2200W".
Yes! - 2,200 watts! That is why it boils water so quickly.
What are the ohms law formulas?
To make it much easier for you, I have put all the relevent formulas together for
you here complete with worked examples of ohms law.
You will notice the formulas share a common algebraic relationship with one another.
For the worked examples voltage is E and we have assigned a value of 12V,
Current is I and is 2 amperes while Resistance is R of 6 ohms.
(Note that the asterisk *means multiply by, while "/" means divide by. )
For voltage [E = I * R] E (volts) = I (current) * R (resistance) OR 12
volts = 2 amperes * 6 ohms
For current [I = E / R] I (current) = E (volts) / R (resistance) OR 2
amperes = 12 volts / 6 ohms
For resistance [R = E / I] R (resistance) = E (volts) / I (current) OR 6
ohms = 12 volts / 2 amperes.
Notice how simple it is?
Now let's calculate power using the same examples.
For power P = E2 / R OR Power = 24 watts = 122 volts / 6 ohms
Also P = I2 * R OR Power = 24 watts = 22 amperes * 6 ohms
Also P = E * I OR Power = 24 watts = 12 volts * 2 amperes .
That's all you need for ohms law - remember just two formulas:
For voltage E = I * R and; for power P = E2 / R
You can always determine the other formulas with elementary algebra.
Ohms law is the very foundation stone of electronics!
Knowing two quantities in ohms law will always reveal the third value.
I suggest you print these formulas out and paste them onto scrap cardboard to keep your ohms law as a handy reference until you are quite familiar with it.
what is Electrostatic Electricity?
Electrostatic Electricity is generally ignored or forgotten, yet the effects of static electricity can be DEVASTATING to CMOS semiconductors and other electronic components.
It is MOST IMPORTANT, that when working on a Cellular phone, the proper precautions be adopted at ALL TIMES. Ignoring these precautions will result in both costing you a lot of money and possibly destroying vital components on a Cellular Phone.
It is strongly recommended that an antistatic wrist strap and an antistatic mat be used when carrying out repairs. These are available from Celtrain on request.
Handling of CMOS and Electronic Components.
Field Effect Transistors (FET) and IC’s make use of Complementary Metal Oxide Semiconductor (CMOS) technology.
CMOS transistors and IC’s WILL BE DAMAGED by ELECTROSTATIC ELECTRICITY.
Electrostatic Electricity is bad in dry areas, and areas covered by NYLON floor covering.
When purchasing CMOS transistors, IC’s etc, they are normally supplied in a special conductive package which shorts out all pins, this may cause predamage. IC holders or sockets should be used to minimise handling.
ALWAYS LEAVE IC’s in it’s protective packing until you need to use them.
Sit down (Preferably in an area that does NOT have a nylon floor cover) and connect yourself to EARTH so as to discharge any Electrostatic charge on your body. Put on a wrist strap and connect this to ground.
Working on an ELECTROSTATIC MAT, remove the IC from it’s packing.
DO NOT TOUCH THE PINS!!!!!!!!!!!
Place the IC the correct way around into the IC holder being careful NOT to bend the pins.
Footnote: TAKE NOTE OF THE DANGERS AND DAMAGE THAT CAN BE CAUSED BY WORKING ON CELLULAR PHONES WHEN YOU ARE CHARGED UP WITH STATIC ELECTRICITY!
What kind of applications are good for circuit switched services, what are good for packet switched services?
Data services similar to those for GSM are also being developed for IS-136 TDMA and CDMA networks. But as a more mature digital technology, GSM has a strong head start. When GPRS is deployed, no other wireless data technology will be able to match its capabilities. But it is also important to remember that GSM already offers excellent data and fax capabilities that provide more than sufficient capability for many types of applications. As technologies like GPRS become available, the scope of data applications that are practical for wireless connectivity will only increase.

Mobile originating call: How mobile originating call is established from a mobile to fixed telephone network?
The BSS is located between two interfaces, Air and A. From the call establishment point of view, the MS must have a connection through these two interfaces before a call can be established. The MS starts the sequence by sending a message 'Channel Request'. This message contains a reason why the signalling connection through the BSS is needed. After this, the BSC allocates a signalling channel through so-called A-bis interface located between the BTS and the BSC. When the signalling channel is ready through the A-bis interface, the MS is told to move to the signalling channel in the Air interface. The MS informs it is on the signalling channel which then triggers the BSC to set up the A interface, i.e. the BSC requests the SCCP connection. When a signalling connection between the MS and the NSS has been opened as described, the MS starts the other signalling sequences in order to completed the original requested task

Incoming calls: If a user has subscribed voice, data, and fax services and the mobile is attached to GSM network, how the user can control which kind of calls (voice/data/fax) she wants to now receive?
The problem remains when the only information received by the GMSC is the called number (the MSISDN). Two solutions of general application have been put on the table. The first solution consists of letting the service be chosen by the called party. The message setting the call from the network to the mobile station does not specify the service, and the mobile station indicates it in return. This solution imposes the requirement that the service is set by the user in the mobile station before the actual start of the communication. A typical scenario to send a fax to a GSM subscriber is then first to phone him (speech communication), asking him to set the mobile station so that the next call will be treated as a fax call; then hang up and re-dial to establish the fax call.
This solution has minimal impact on network, but is not very convenient for the users. This is why an alternative solution was proposed, consisting in providing a GSM subscriber with as many MSISDNs as services for which he wishes to receive incoming calls ( for instance a speech number and a fax number). The service can then be chosen by the calling party, by using the right number. The relationship between numbers and services is held in the HLR.
Data call:
a) the mobile station
b) from the mobile station to the base station; the radio path
c) from the base station to the MSC
d) from the MSC to IWU (Inter Working Unit, special modem-like device)
e) from the IWU to AM (Analogue Modem)
The GSM-only components of these data/fax interfaces are not actually modems as we traditionally understand them: the "modem" component you need to send and receive data actually resides at the network headquarters (also known as the Mobile Switching Centre, or MSC), using a special modem-like device called an IWU, or Inter Working Unit.
Data is sent digitally from the PC via the special hardware adapter, through the phone and then through the air to the IWU. The GSM phone and the data/fax interfaces thus act as one extended digital "serial" or "air-interface" link between the PC and the IWU, which now acts as the Analogue Modem.
It is only when the digital data is received by the IWU that it is converted by the IWU to the analogue Frequency Shift Keys (FSK) tones characteristic of Analogue Modems, making it possible to connect via Telkom fixed-lines to an ordinary Analogue Modem. And if an ordinary fax machine or fax/modem sends data to your mobile phone, then the IWU converts the analogue tones received into the "digital data stream" suitable for transmission across the network to your GSM mobile.
If one mobile unit sends fax or data to another mobile, then there's no need for an analogue-to-digital conversion since the entire "air interface" is already digital, as is required by the GSM specification
Transparent vs. Non-transparent: What is the difference between transparent and non-transparent data?
Transparent Data Transmission: A method of transmission in which the transmission medium will not recognize control characters or initiate any control function. Transparent-based phones do not utilise any error correction. Thus the data sent and received MIGHT be corrupted unless a greater than two-bar cellphone signal is used (South African conditions). Non-transparent data uses a special ensure robust GSM-specific error correction technique called RLP for transmission. [6]
Non Transparent communication utilises a special GSM network-based error correction facility called "Radio Link Protocol" (RLP)that ensures more robust transmission. What this essentially means is that the GSM network's IWU will add special error correction codes to control the flow of data.
This ensures that the data transmitted first obtains a special acknowledgement signal from the receiver that informs the transmitter that the data has been received as transmitted and that the receiver is ready to receive the next set of data from the transmitter. If there is no such acknowledgement signal from the receiver, the networks will utilise their "data buffering" feature by using a special "forward correction" technique to ensure uninterrupted data transmission throughout. Not all cellphones support GSM's Non Transparent (RLP-based) data capabilities.
Transparent data transmission means that there is no GSM error correction supplied over the air interface.
Non-Transparent data only applies to data transfers and not faxing since the Group 3 standard for fax transmission is a transparent protocol.

Power Section:
A power section deals with power related tasks such as power distribution or charging the battery so this section can be divided into two sub sections like.
1. Power Distribution
A power distribution section is built around an "power IC" it takes 3.6V power from battery and regulates its power and then distributes to the other components used in mobile phone circuit. in some mobile phones tech "RF Power amplifier" uses more Power than provided bye mobile phone's battery .i.e. 4.7 V or 5.6 V in some phones. the power Ic with a power boaster coil is used to increase voltages. so we can say that power IC is used to provide power to other components how much they needed. either less than battery voltage or more than it.
* Charging Section
A charging section works for battery charging purposes.it is often consists a fuse, a coil, a protecting diode, a filter capacitor and charging IC and some other discreet. the charging section helps battery to be charged when it needs and when battery is charged, charging IC reads its state of charge and feels it full charged and then disconnects charging from it.
Radio Section:
A radio section has basically a set of four main functions.wich are.
*
* Receiver
Band Switching:
In the modern mobile phone communication techniques. the frequency of mobile phone communication is divided into three bands
*
* PCS (operates on 1900 MHz)
the third band is used only in USA whereas the first two bands are used in the rest of the world. band switching is done bye a "ceramic antenna switch" it reads from the radiation dispersed in the air and then switches to the appropriate band.
in the very first phase of mobile phones there were single band handsets which operated on single frequency band but now a days all the handsets are dual band or tri band in operation.
RF Power Amplifier
RF power amplifier is often called as ".PA" or"Transmitter" its functions is to amplify or boast the power which is being transmitted to air, so may it would be able to communicate with long distances. a typical .PA can amplify rf power up to 0.6W or 600mW. This amount of rf power is sufficient to communicate nearly 20 to 25 kilometers in open area, but all the PA's are controlled by there rf signal processor, so if we are near our cell base tower the PA of our phone will transmit low power but if we are far away it will produce its maximum power.
Transmitting
A mobile phone's rf section is basically built around an rf IC which is often called rf signal processor whereas in nokia it is called hagar IC in some hand sets and in some hand sets it is called Mjoelner. irrespectively of the brands and verity of names we call it rf signal processor. this IC works as transmitter and receiver as well. working as transmitter it takes instructions from phone's computer and also takes audio data from audio section and creates radio waves then mixes audio data to its radio waves according to the instructions given by computer section. this mixer of audio and radio is sent to PA to amplify its strength
Reciever
A reciver section for rf waves is built in rf IC, as it is said that this IC works for dual purposes first transmitting and section recieving. in the recieving section of mobile phones a radio signal is gather from ceramic antenna switch and then it is filtered and sent to rf IC to further process. in rf IC signal is detected and then rectified for audio and data which is sent to audio IC or computer section.
Computer Section:
A computer section in mobile phone consists of two main functions
CPU(central processing unit)
Memory (RAM, FLASH, COMBO CHIP)
CPU:
A CPU is used in mobile phones as a central processing arithematic or controler. the cpu controls various functions in mobile phones like signal, display, sound converting(DSP), charging, power on, rf channel controler, rf tx power conroller, LEDs, vibrator, data processing, data storing etc. so we can say that if a cpu is damaged in any mobile phone it cannot be repaired unless the CPU is not replaced but this type of fault is not even seen to me ever either memory chips can be damaged. in brand Nokia CPU is named with two different words (MAD or UPP)
Memory:
there are two main types of memories used in mobile phones
* RAM (Random Access Memory)
The RAM is used in mobile phones to store user data in mobile phones. So these a days we can store pictures, messages, ringtones, applications, themes and other these type of things in mobile phones so CPU stores these types of data in the RAM of our mobile phones.
* Flash (eeprom, ROM etc)
The flash chip is used in mobile phones to hold mobile phone's operating system in it. so if the flash chip is damaged in mobile phones the phone cannot power on properly because all the instructions to start a mobile phones and its various tasks like call making , display etc are stored in the flash chip of mobile phones.
* Combo Chip
In smoe mobile phones there is a combined type of memory used which is called combo memory chips these types of memories work for both like RAM and Flash.
WHAT ARE DIODES AND HOW LEDs WORK ?
Diodes are components that allow current to flow in only one direction. They have a positive side (leg) and a negative side. When the voltage on the positive leg is higher than on the negative leg then current flows through the diode (the resistance is very low). When the voltage is lower on the positive leg than on the negative leg then the current does not flow (the resistance is very high). The negative leg of a diode is the one with the line closest to it. It is called the cathode. The postive end is called the anode.
Usually when current is flowing through a diode, the voltage on the positive leg is 0.65 volts higher than on the negative leg.
A diode allows electricity to flow in one direction only and blocks the flow in the opposite direction. They may be regarded as one-way valves and they are used in various circuits, usually as a form of protection. There are different types of diode but their basic functions are the same. These are noted below along with examples of diodes in use.
How Light Emitting Diodes Work
Light emittingdiodes,commonlycalled LEDs, are real unsung heroes in the electronics world. They do dozens of different jobs and are found in all kinds of devices. Among other things, they form the numbers on digital clocks, transmit information from remote controls, light up watches and tell you when your appliances are turned on. Collected together, they can form images on a jumbo television screen or illuminate a traffic light.
Basically, LEDs are just tiny light bulbs that fit easily into an electrical circuit. But unlike ordinary incandescent bulbs, they don't have a filament that will burn out, and they don't get especially hot. They are illuminated solely by the movement of electrons in a semiconductor material, and they last just as long as a standard transistor.
In this article, we'll examine the simple principles behind these ubiquitous blinkers, illuminating some cool principles of electricity and light in the process.

What is capacitance?
Now a capacitor (formerly condenser) is an Electronic Component which has the ability to hold a charge of electrons. Sounds like similar to a Battery ? , you are not very wrong !
The Capacitor is somewhat like a Battery , but has some very different properties also .
The number of electrons it can hold under a given electrical pressure (voltage) is called its capacitance or capacity. Two metallic plates separated by a non-conducting substance between them make a simple capacitor. Here is the symbol of a capacitor in a pretty basic circuit charged by a battery.
The time required for a capacitor to reach its charge is proportional to the capacitance value and the resistance value.
The time constant of a resistance - capacitance circuit is:
T = R X C
where T = time in seconds
where R = resistance in ohms
where C = capacitance in farads
The time in this formula is the time to acquire 63% of the voltage value of the source. It is also the discharge time if we were discharging the capacitance. Should the capacitance in the figure above be 4U7 (4.7 uF) and the resistance was 1M ohms (one meg-ohm or 1,000,000 ohms) then the time constant would be T = R X C = [1,000,000 X 0.000,0047] = 4.7 seconds. These properties are taken advantage of in crude non critical timing circuits.
Capacitors in series and parallel
Capacitors in parallel ADD together as C1 + C2 + C3 + ..... While capacitors in series REDUCE by:
1 / (1 / C1 + 1 / C2 + 1 / C3 + .....)
Consider three capacitors of 10, 22, and 47 uF respectively.
Added in parallel we get 10 + 22 + 47 = 79 uF. While in series we would get:
1 / (1 / 10 + 1 / 22 + 1 / 47) = 5.997 uF.
Note that the result is always LESS than the original lowest value.
Simplified calculations for Capacitors
We said above that parallel combinations simply add the values together. Series combinations are somewhat more difficult requiring 1 / (1 / C1 + 1 / C2 + 1 / C3 + ...).
This can be simplified somewhat to:
[(C1 X C2) / (C1 + C2)]
Try three or more in series. Do the first two then arrive at an intermediate value, then do the third with the intermediate value and so on.
A very important property of Capacitors
Capacitors will pass AC currents but not DC. Throughout electronic circuits this very important property is taken advantage of to pass ac or rf signals from one stage to another while blocking any DC component from the previous stage.

Know the Mobile Phone with Blocks
Have you experienced the fact that in a music listened from a very long distance, the sounds of drums are less audible than the sounds of other sharp instruments like guitar ?
YES
This is because the sound of a drum is a low frequency signal and low frequencies cannot travel long distances easily while the high frequencies like the sound of guitar or other string instruments can !
See how this is applied in the Radio, TV and Mobile Technology for yourself. After all the Mobile Phone is also a radio telephone ! The broad meaning of the word "Radio" is WIRELESS. The principle of a mobile phone can be compared with that of a Radio or a television system.
The Voice signal which is required to be sent to the other mobile phone is first converted from Analog to Digital type of Signal and is then mixed with a very high frequency signal in the mobile phone , this is called Modulation which means changing the signal by adding another frequency called carrier frequency to carry it. This is done to make it possible to be sent thro' Air to the nearest tower of the service operator. The basic principle being that the High Frequencies can travel longer distances easily. This was the transmitting part. (In Radio or Television systems, this is done at the Transmitting End which is the Radio or the TV Station.)
In the receiving part, the reverse (De-Modulation) is required to be done. The received signal from the service operator's tower is required to be Demodulated to remove the High Frequency Signal OR the carrier frequency signal from the received signal, so that only Digital Audio signal is left out. In Mobile Phones, this Digital Audio Signal is then converted to Analog Signal and after some amplification etc. is sent to the speaker to be heard by the user. (In Radio or Television systems, this is done at the Receiving End which is the Radio or the TV itself !)
Both this Transmitting (Tx) and Receiving (Rx) functions are required to be carried out in the Mobile Phone itself and is done by what can be called the RF section of the mobile phone.

Biography of Paris Hilton
Paris Whitney Hilton
born: 17-02-1981
birth place: New York, USA
The daughter of Richard Hilton and the actress Kathy Richards, Paris Whitney is the oldest of four children. Together with her three siblings, Nicky, Barron Hilton II and Conrad Hilton III, she is heir to the considerable Hilton fortune which has been built on a successful real estate and hotel business.
Acting is in Paris’s blood. Not only is her mother an actress, she is also the niece of two popular child stars of the 1970s, Kim Richards and Kyle Richards, who featured in the movie, Escape to Witch Mountain and TV shows as Little House On The Prairie and ER. Paris is also related to the famous Hungarian actress Zsa Zsa Gabor, who was married to Paris’s great grandfather, Conrad Hilton. She is also distantly related to the famous movie star Elizabeth Taylor, who was briefly married to Paris Hilton’s great uncle, Conrad Nicholson Hilton Jr.
Paris was born with the proverbial “silver spoon in her mouth”, and spent her childhood moving between five-star luxury homes. These included a suite at the Waldorf Astoria Hotel in Manhattan, New York, as well as mansions in exclusive Beverly Hills and the Hamptons. At present, she lives in a $10 million house in the Hollywood Hills which she shares with her sister. Paris attended her freshman year of high school at the Marywood-Palm Valley School in California, before continuing her studies at the Dwight School in New York.
Paris Hilton is no stranger to the limelight, and has been in the public eye since childhood. She began modeling as a child, initially at charitable functions. In 2000, she signed up with Donald Trump’s modeling agency, T Management. She also worked with other top agencies, including Ford Models Management in New York, and Model 1 Agency in London. She has fronted leading advertising campaigns such as Christian Dior and Tommy Hilfiger, and was soon christened “New York’s leading IT girl”.
Not content with her modeling career, Paris was anxious to make her debut in show business, with television likely to offer the best platform for her talents. In 2003, she teamed up with her long-time friend Nicole Richie to star in the 2003 Fox TV hit reality series, The Simple Life. For the purposes of the programme, the two girls tried their hand at a variety of blue-collar jobs, and started out by living with a family on their farm in rural Arkansas. The series showed the girls hanging out with the local boys, working at their manual jobs, and performing all sorts of menial everyday tasks, which were clearly at odds with their luxurious upbringing and lifestyle! The Simple Life was such a big hit that it was promptly followed by three more series, respectively subtitled: Road Trip, Interns and ‘Til Death Us Do Part.

Biography of Shakira
Shakira
born: 02-02-1977
birth place: Barranquilla, Colombia
Born to parents of Colombian and Lebanese decent, Shakira Mebarak discovered her love of music at an early age. Penning her first song aged 8, she thrived on a healthy mix of both world music and bands as diverse as Led Zeppelin, the Beatles and Nirvana. One of her first songs was called ‘Tus Gafas Oscuras’ (Your Dark Glasses), about her father’s grief at the loss of his son in a car accident.
A regular on the local Colombian talent show circuit, Shakira got her lucky break after moving to Bogotá, initially with hopes of pursuing a career in modelling. Thanks to local theatre producer Monica Ariza, the talented young star-to-be was thrust under the nose of Sony Colombia executive, Ciro Vargas. Following a successful live showcase, Shakira was signed to the label and went on to release her fist album, ‘Magia’ in 1991. The album failed to grab attention on the international market, but did wonders for Shakira’s profile in her home country. A second album, ‘Peligro’, in 1993 left Shakira dissatisfied with the music industry and she returned home to take a role in the Colombian soap opera, ‘El Oasis’.
Shakira’s first English album, ‘Laundry Service’, released in 2001 was to be the catalyst that would launch the young star onto the international stage. Thanks to the collaborating talents of Gloria Estefan, the album went on to sell in excess of 13 million copies and spawned the monster hits ‘Whenever, Wherever’ and ‘Underneath Your Clothes’. The combination of strong Latin rhythms and Shakira’s unique voice made her instantly recognisable.
In 2002, Shakira set off on a world tour entitled ‘Tour of the Mongoose’. This unusually named show was based on the little known fact that a mongoose can defeat a cobra. Huge visuals to demonstrate this were even beamed onto screens to dazzle, and probably terrify, audiences.
Following this exhausting tour, Shakira took a break from recording leaving her record company to satisfy hungry fans with a remix collection ‘Laundry Service: Washed and Dried’ in 2002 and a live album, ‘Live & Off the Record’ in 2004.
Having amassed a healthy collection of both English and Spanish songs, Shakira released both ‘Fijacion Oral, Vol. 1’ and ‘Oral Fixation, Vol. 2’ in 2005. Both albums performed well thanks to a string of awards, including the 2005 MTV ‘Best Female, and the phenomenally successful second single ‘Hips Don't Lie’ featuring Wyclef Jean. In 2006, the duo was invited to perform the song to millions of football fans at the 2006 World Cup.
2006 proved to be a hugely successful year for the young talent after she received 6 Latin Billboard Awards, making her the biggest winner of the night. She was also honoured at a United Nations ceremony thanks to her Pies Descalzos Foundation, a charity that helps to protect children from violence in Colombia.
On the personal front, Shakira began dating the son of the then president of Argentina, Antonio de la Rúa in 2000. The couple have since become engaged and Shakira has said that she plans on having two children.
As her career continues to soar, it appears that Shakira has taken up where Britney and Co. have left off in terms of worldwide teen appeal.

Biography of Britney Jean Spears
Britney Jean Spears
born: 02-12-1981
birth place: Kentwood, Louisiana
For her relatively short nine years in the public spotlight, Britney Spears has managed to generate more controversy than your average celebrity manages in a lifetime.
From the outset, her sexually provocative image, aided by the slickest hit-making machine, has guaranteed non-stop headlines and constant media scrutiny.
It is all a long way from young Britney’s first televised performance on StarSearch in 1990. This led to the eight year-old Spears auditioning for Disney’s The Mickey Mouse Club. Initially she was deemed by producers as being “too young” but, undeterred, she finally made the cut, aged eleven and appeared singing, dancing, even rapping her way through 110 appearances, alongside fellow Mouseketeers Justin Timberlake and Christina Aguilera.
The show’s cancellation in 1994 left Britney’s future uncertain. Demo tapes led to an audition for Jive Records in which she performed 'Jesus Loves Me' and 'I Have Nothing' by Whitney Houston, to amazed record executives, who signed her instantly.
Appearing as the opening support for *NSYNC’s 1998 tour paled into insignificance with the release, in December 1998, of her first solo single, '…Baby One More Time', which achieved 9 million sales worldwide. Dressed in a provocative Catholic-schoolgirl outfit in the memorable video, the debate over sexual exploitation raged, spurring record sales.
A hugely successful first album was succeeded by the hit-laden 'Oops I did It Again', a skilful retread of the formula. However, Britney’s private life was beginning to capture as many headlines as her music career. Dating teen heartthrob Justin Timberlake, they made the perfect pop couple, until the relationship died three years later.

Biography of Michael Jackson
born: 29-08-1958
birth place: Gary, Indiana
In the mid 1960s, Michael, along with his brothers Jackie, Tito, Jermaine and Marlon, were formed into ‘The Jackson 5’ by their father. The group began singing in local clubs and bars and were signed to Motown Records in 1969. The family moved to California and the first four singles released by the group, 'ABC', 'I Want You Back', 'The Love You Save' and 'I’ll Be There' all reached number 1 in the charts. Jackson and some of his siblings would later claim that their father was a strict disciplinarian in this period, and have alleged varying degrees of physical and mental abuse.
In 1976, the group left Motown and renamed themselves ‘The Jacksons’. Despite a flexible line-up, including brother Randy and younger sister Janet, and the growing solo career of Michael, the Jacksons released another six albums and toured all over the world until 1984.
In 1978, Michael appeared as the Scarecrow in the film version of the musical ‘The Wiz’, a soul adaptation of the Wizard of Oz story. Whilst the film was not a huge success, and the teenage Jackson complained bitterly about the effect of the heavy make-up on his adolescent acne, it was here that he met the film’s music producer – Quincy Jones.
Jones produced the first three solo albums for Michael. The first, 'Off the Wall' was a departure from the more traditional Motown sound of the Jacksons and, whilst it was a hit, both critically and commercially, it was not enough to separate the young singer from the family group entirely. The next album, 'Thriller', would change all that and more.
'Thriller' has become the best-selling album of all time, shifting well over 50 million copies to date. The videos that accompanied the singles released from the album set new standards for complexity, length, expense, spectacle and cinematic intent, that continued to be a feature of Michael's career. The first video, 'Billie Jean', became the first video by a black artist to be played on the young MTV network.
The 'Thriller' video was ambitious from the start. Hiring an established cinema director and using state-of-the-art make-up and special effects, the homage to horror films is widely acknowleged as one of the most influential of all time. The album went on the win Jackson seven Grammys in 1984, with the artist winning another for narrating 'The E.T. storybook'. The eight awards was a record only later matched by Carlos Santana
Tips and Tricks 4 ur Symbian Mobiles - Interesting
Tip 1 : Do u know how to use the edit button (abc or pencil button)?
Heres how... in the inbox for example; u wanna delete multiple sms, simply hold the edit button, scroll down, and then, press c to delete the marked sms. The edit button can also b used to copy and past text in sms, simply hold it and scroll across, choose copy. pretty good for placing song names in ngages
Tip 2 : Shit happens, on a smartphone, its inevitable u do something wrong, and tis calls for a format of fone. to format the fone, press *#7370#, then enter the lock code, which is the sec code of the fone. NOTE: batt must b full, else if format is disrupted by low batt, consequences will b disatrous
I heard the code *#7780# works too, pretty much the same i tink.
for 6600 users, to format the fone, theres an alternative way. Press and hold <3>, <*>, and the buttons, then power on fone, keep holding on the 3 buttons, till u come to a format screen. tis method ONLY works on 6600, and need not enter the sec code. BUT sec code wun be reset to default 12345.
Tip 3 : TO NGAGE USERS; Did u know u can install .sis files simply using the cable given? Juz plug it in, place the .sis file anywhere on e: (the mmc), not in any folders, root of e:, disconnect, then look for it in manager.
Tip 4: Save on battery and system memory being used by regulary checking the task
Tip 4a: Set the screen saver to a short time out period to prolong battery life.
Tip 4b: Avoid restarting the phone, or repeatedly turning it on and off. This helps increase battery life.
manager which can be accessed by holding down the menu button!!
Tip 5: Type *#06# to display your IMEI serial number, very valuable for the unlocking your phone to other sim cards
Tip 6: Type *#0000# to view which firmware version you are running
Tip 7: If you would like to avoid being "blue jacked", keep bluetooth turned off, or set your phone's visibility to hidden.
Tip 8: Don't want to carry a watch and a phone? Set the screen saver to show date and time, then you can ditch the watch.
Tip 9: Save memory when installing apps, by installing over bluetooth. This can be done using the nokia phone suite and a bluetooth serial connection. Only works with .SIS files, so java still has to be sent to the phone, but will save space when using .SIS files.
Tip 10: Operator logos
Use a filemanager like FExplorer or SeleQ to add the folders: "c:/system/Apps/phone/oplogo". Add a .bmp picture to folder "oplogo" and restart your phone! The .bmp picture size needs to be: 97 x 25 pixels
Tip 11: Check if the recepients phone is on
Delivery reports
or
Type *0# your message in the message composer window space then write your message, the recipient will not see the star zero hash bit - just the message When they read it it will relay a message back to your fone showing the time they recieved it. (haven't yet tried it myself though)
Tip 12: BlueJacking
First up, you need to know what Bluetooth is. There are lots of types of modern devices that incorporate Bluetooth as one of their many features. PDAs, mobile phones and laptops are a few of these modern devices. Bluetooth means that Bluetooth enabled devices can send things like phonebook/address book contacts, pictures & notes to other Bluetooth enabled devices wirelessly over a range of about 10 metres. So, we've got past the boring part. Now, using a phone with Bluetooth, you can create a phonebook contact and write a message, eg. 'Hello, you've been bluejacked', in the 'Name' field. Then you can search for other phones with Bluetooth and send that phonebook contact to them. On their phone, a message will popup saying "'Hello, you've been bluejacked' has just been received by Bluetooth" or something along those lines. For most 'victims' they will have no idea as to how the message appeared on their phone.
Tip 13: While you are viewing a picture in your phone's gallery, press one of these shortcut keys (definitely works on 6600, not sure about other symbians)
1 - turn image anticlockwise
3 - turn image clockwise
* - toggle on/off of full screen
5 - zoom in
0 - zoom out
#15 u can select all files in a folder by selecting THE folder and copy it then paste it somewhere. however u need to make a new directory. fexplorer wun let u copy that folder together. well seleQ can mark files to copy but it really takes time!
#16: A soft and Hard reset
A Soft-reset - the process of resetting all the settings of the phone to the factory default! No applications are deleted! A Hard-reset is like formatting a drive! It does format the memory. Everything that has been installed after the first use of the phone is deleted! It will recover the memory of the phone to the state you purchased it! It is done by inputing the following code: *#7370# NOTE: The battery must be full or the charger has to be connected to the phone so that it does not run out of power and make the phone unusable.

Why assigning Video Recorder in the right or left soft key does not work?
(Sound Recorder is launched instead of Video Recorder)
It's a bug with firmware version 2.50.
How to check your firmware version:
A "Firmware" is the phone's operating system stored in internal Flash memory of the device (disk Z.
Manufacturers release new firmware versions containing bug fixes, improvements and - sometimes - offering new functions.
Firmware upgrade can only be made in authorized Nokia service centre (point).
To check your current firmware version simply type *#0000# on main Phone screen.
·
How to check your IMEI (International Mobile Equipment Identity)?
Type *#06# on main Phone screen.
Start up in Safe Mode so no 'auto start' apps will be running:
To make sure that no memory-resident programs start when you reboot your phone,
hold down the pencil key when you turn on the phone and hold it on untill you have to enter your PIN code.
(When you have trouble booting up the phone with the MMC in it because it got corrupted for some reason, this trick will
almost always let you boot up the phone so you can remove the latest installed app which might have caused the
problem or if your phone is "unrepairable" you can still back up your important data before you do a format.)
Q: How to totally format your Nokia 3650 and remove all installed applications, user files and restore all
settings to default like it's new out of the box? (OEM apps won't be deleted like Camera and RealOne Player).
A: First Format your MMC: Menu > Extras > Memory > Options > Format mem. card > Yes.
Note: It is very important to format your MMC before you format your phone!
Then format your phone by typing *#7370# on main Phone screen.
Phone will ask: "Restore all original phone settings? Phone will restart." Press 'Yes' and enter your Lock code (default is 12345).
Tip: Formatting takes several minutes so you'd better connect your Nokia 3650
to a charger to ensure that your battery doesn't get empty in the middle of formatting.
Note: All your created acces points and mailboxes will be lost so take a note of them. And all application settings will be reset.
E.g. In Camera, image quality is set back to normal and memory in use is set back to phone memory. And also in Messages,
memory in use is set back to phone memory, etc. Also backup your contacts with PC Suite or a program like Contacts Manager.
To reset your wallet, should you forget your code,
Type in:
*#7370925538#
this will reset the wallet code, the wallet contents will be deleted.

How to free more RAM on your phone >>>
>>> Method 1: Flight mode:
Put your phone in "Flight mode" with Psiloc System Tools. Install System Tools, open it and select "Flight mode". This way you can restart the phone without your SIM card so there will be no running phone tasks in the background. Now you can have up to 3,5 MB of free RAM!
Note: ironically enough, Flight mode doesn't work when Smart Launcher is installed, at least in my case.
But i've also heard several reports of people who have both apps running without any problems.
>>> Method 2: Smart Launcher trick:
Install Smart Launcher and open it. Go to Options, Settings and put Launcher ON.
Now plug in your charger and switch off your phone. Wait untill the battery meter appears and short press the Menu button (don't hold).
The menu should appear and now you can have 3,5 to 4,5 MB free RAM! (Hold Menu button to check RAM).
The trick is that with the charger plugged in, the phone must get a minimum software support for charging, even when
the phone is switched off. And somehow Smart Launcher has still got it's shortcut running and that's the Menu button. So when
you press the Menu button, you go directly to the Menu without any other phone tasks running in the background so
you trick the phone and you have more free RAM!
Note: when you unplug the charger, the phone will switch off.
>>> Method 3: Menu :
This method I found it by myself, it frees a little about 100~200 KB but I guess it's useful sometime
Close your menu not by selecting the right selection key "exit", or pressing the menu key another time, they only hide the menu app but do not close it, to close it select the left selection key "option" and scroll down and select "exit"
So when you open an app needs more ram reopen menu and close it, it's useful when play low bit rate video in realplayer paradis.

How to repair DEAD hard drive! VERY USEFUL
Hard Drive Repair
If the problem is a head crash, or the infamous Seagate "stiction" problem it is really not too difficult to fix your own hard drive if you know what to do.
You will require #00 steel wool, paint thinner or gasoline, WD-40, a few hand tools, and about 45 minutes.
First, you need a clean room, so make sure the garage door is closed before you begin. Move those old lawnmower parts off the bench.
Disassemble the sealed unit and carefully wash all parts with the paint thinner or gasoline. Bend the read/write heads out of the way and then disassemble the platter stack.
VERY CAREFULLY buff the platter surfaces with the #00 steel wool. This will remove any existing data, level out any surface defects, and help to redistribute the magnetic media and fill in those irritating "bad sectors" that most drives have.
Reassemble the platter stack, and using a .015" feeler gauge, bend the read/write head back to the platter surface, using the feeler gauge to set the gap. This is a slightly higher gap than the factory uses, but it reduces the chance of head collisions with any dirt you neglected to remove.
Give the head and platters a good shot of WD-40 and reassemble the unit. If your drive has a filter, replace it with a clean section of gauze pad.
All that's left is to low level and DOS format the drive, and you're back in business.
If the above does not fix the drive then download this eBook

Learn How 2 Stoppie UR Bike
While on the ride apply the brake smoothly
50 kmph stoppie - sliding/skidding may occur in initial try.
10 kmph stoppie - Better trick for initial bikers
I prefer that u better start with the second one(10 kmph). Because at 10 kmph, we have a lot more confidence. And it's much
safer. Doing it slowly and smoothly are the most important thing.
You grab the front brake slowly at first and apply progressively more brake until the front end is fully loaded (put ur bdy
weight 4wrd, push those discs).
Loading the front forks is important, because it transfers the forces from the bike's weight onto the front before you bring
the rear up. You can't just get a stoppie by instantly applying full front brake! That'll just slide the front (even at 10
mph if you pull too fast).ages.
Don't use any rear brake and don't expect the rear brake to keep you from going over like it does with wheelies. In fact, if
you apply the rear brake while the rear wheel is up in the air, it'll make it harder to balance when you come back down
Balancing is pretty important to pull off the trick without embarassment. Usually, a fouled stoppie will simply make you put
your foot down. Keep the bike in 1st gear, because you'll want to accelerate once you come down to stabilize the bike (and
leave the spectators behind !).
ready to go again! Landing a little crooked, but still perfectly balanced looks even cooler for some reason.
There are more subtle tricks like standing up on the pegs a little before braking to make it last longer, but I wouldn't try
that for starters.
Have fun and ride safe always!
Learn How 2 Do A Wheelie With UR Motorbike
Try 2 have a motor bike which is above 600cc. Other bikes will do but with less power and u need to struggle. U must have more confidence in u. Including patience Better start with 20-25 kmph.Bikes which I advice to be safe:
Yamaha R1 - CBR 900 – 1200 Bandit – suzuki Hayabusa- etc,(These types of bikes are the easiest of all for wheelies because they will wheelie off the throttle in first gear without trying hard at all.)
Time to start:
Start slow, probably 20-25 MPH is the best to do stunt like wheelie, or stoopie. Play with your clutch when trying to boost the speed of your bike, keep your body lean backward a little bit. Keep your fingers on the hand brake lever, and while you reving up the throttle, do a quick blip on the clutch and it should bring your bike up. Try to stabilize your bike, don't put too much or too little Acceleration. When you wanna bring down the bike, just press the brake pedal with your right foot, do it slowly so it won't hurt your shock.WARNINGS:
Make sure you buy a used bike when doing your stunt, so you don't lose so much when you total your bike. It needs a lot of practice to find the balance point for your bike and your body. Wear protective gear and make sure to have friends with you in case something bad happened. Tires need to be properly inflated and all gears are in good conditionFriday, August 24, 2007
All Unknown - Windows XP Tricks
shtcut to restarting xp..
You can restart a Windows XP Pro and home machine easily by creating a shortcut with following path. (Assume you installed Windows XP on your C: Partition) "c:\windows\system32\shutdown.exe -r -f -t 00" -r is for restarting the computer. -f is to force close all programs without saving. -t 00 is used to restart in zero seconds. i.e. as soon as you D.Click on the shortcut. You can log off from a Windows XP Professional or home edition by running "C:\windows\system32\shutdown.exe -l -f -t 00". Also you can shutdown a Windows XP home or Professional edition by running "c:\windows\system32\shutdown.exe -s -f -t 00". You always have to turn from the CPU after running this command. (Same with AT and ATX powered machines.) If you want to turn down power of ATX machine automatically, run "c:\windows\system32\tsshutdn.exe 00 /POWERDOWN /DELAY:00" This is used to turn off a server. Even though your computer will be
shutdown completely, this whole operation will take 30 seconds to finish. Even though you don't have networked computers attached to your computer, this works.
1) Disabling Display of Drives in My Computer :
This is yet another trick you can play on your geek friend. To disable the display of local or networked drives when you click My Computer go to : HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\Explorer Now in the right pane create a new DWORD item and name it NoDrives. Now modify it's value and set it to 3FFFFFF (Hexadecimal) Now press F5 to refresh. When you click on My Computer, no drives will be shown. To enable display of drives in My Computer, simply delete this DWORD item. It's .reg file is as follows: REGEDIT4 [HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\Explore r] "NoDrives"=dword:03ffffff
2) Pop a banner each time Windows Boots :
To pop a banner which can contain any message you want to display just before a user is going to log on, go to the key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\WinLogon Now create a new string Value in the right pane named LegalNoticeCaption and enter the value that you want to see in the Menu Bar. Now create yet another new string value and name it: LegalNoticeText. Modify it and insert the message you want to display each time Windows boots. This can be effectively used to display the company's private policy each time the user logs on to his NT box. It's .reg file would be: REGEDIT4 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Winlogon] "LegalNoticeCaption"="Caption here."
3) Great trick Lock ur PC yourself
lock ur pc.. open notepad copy and paste the script below and save it .VBS extention
This wil create a shortcut.. run(click) it
set WshShell = WScript.CreateObject("WScript.Shell")
set oShellLink = WshShell.CreateShortcut(wshShell.SpecialFolders("D esktop") & "\LockWorkstation.lnk")
oShellLink.TargetPath = "%windir%\system32\rundll32.exe"
oShellLink.Arguments = "user32.dll,LockWorkStation"
oShellLink.Save
4) Deleting System Options from the Start menu :
You can actually remove the Find and Run options from the start menu by performing a simple registry hack. Again like always Launch the registry editor and scroll down to the below key: HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\Explorer Right-click on the right pane and select New, DWORD Value. Name it NoFind.(To remove the RUN option name it NoRun). Double-click the newly create DWORD to edit it's value and enter 1 as its value. This will disable the FIND option of the Start Menu and will also disable the default Shortcut key(F3 for Find.) To restore the Run or find command modify the value of the DWORD to 0 or simply Delete the DWORD value.
5) Cleaning Recent Docs Menu and the RUN MRU :
The Recent Docs menu can be easily disabled by editing the Registry. To do this go to the following Key: HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\Explorer Now in the right pane, create a new DWORD value by the name: NoRecentDocsMenu and set it's value to 1. Restart Explorer to save the changes. You can also clear the RUN MRU history. All the listings are stored in the key: HKEY_USERS\.Default\Software\Microsoft\Windows\Cur rentVersion\Explorer\RunMR U You can delete individual listings or the entire listing. To delete History of Find listings go to: HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Explorer\Doc Find Spec MRU and delete
6) Can u Delete Recycle Bin?
1 thing is 4 sure, delete option can be added 2 recycle bin...
the old registry thing will work out.....
* launch d registry...
* open HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\ShellFolder
* to add a rename and delete option, change the Dword attribute to 70 01 00 20
* refresh and reboot the system..... u r done.
PS: always backup ur data as well as registry b4 attempting 2 work on it if u r a newbie....
7) To change the icons used for specific drives in explorer
Open regedit by typing regedit into start->run
then navigate to
HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Explorer
now create a key(KEY not VALUE!!) called DriveIcons under Explorer...
now within DriveIcons, create another key with the drive letter you want to change (e.g.,HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Window s\CurrentVersion\Explorer\DriveIcons\K)...
create another key within the drive letter key called DefaultIcon...
now set the default String value equal to the icon you want to use. if you have a file that has more than one icon in it, such as a DLL file, use the standard
C:\full_path\icon_file.dll,n
~ c h e e r s! ~
More
change drive icons.....
first of all copy a icon file to the root of the drive.
example: c:\icon.ico
then create a file called: autorun.inf in c:\autorun.inf
then open that file and type the following:
[autorun]
icon=icon.ico
save and close the file.
now open my computer and resfresh.. and woh! icon changed....
you can apply to other drives too.
be carefull:
"autorun.inf" and "ico.ico" must be in the root of the drive.
example: c:\autorun.inf and c:\icon.ico.
same on the root.
ENJOY, this works on 98 too!!!!!!!!!!!!!!!!!!
8) Hacking windows SEND TO MENU
I know this is a very simple thing but the problem, as like many other issues, is the ignorance about it.
How often do you copy songs from a CD? Or some photos from a CD?
What do you do? You select the required files and do a CTRL –C. Open the destination folder and do a CTRL-V. Here is something you can benefit time from. customize your SEND TO MENU.
This sounds simple and you can do it in less than sixty seconds.
You can create your own BASKET.
First you’ll need access to hidden files. So change your view settings to make all hidden files visible.
Tools -> folder options -> view (tab) and select the show hidden files and folders.
go to parent drive:/documents and settings/(user name)/send to
Open up my computer and locate your most used folders.
Create a shortcut of the most used folders in SEND TO FOLDER.You can do this in a number of ways.
Right click -> send to desktop(create shortcut) and move the shortcut from the desktop to the SEND TO FOLDER
Copy the most used folder and go to SEND TO FOLDER and right click -> paste shortcut.
Also remember to rename the shortcuts to send to videos or send to potos. We don’t need confusion when we use the same later.
5. DONE
~ c h e e r s! ~
9) How to remove the shortcut arrow from the desktop ?
Open Regedit and navigate to the following key:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Shell Icons
Backup the key. More information.
In the right-pane, create a new String value named "29"
Double-click 29 and set its data to:
C:\Windows\System32\shell32.dll,50 (an empty icon)
Close Registry Editor.
Now,
Right-click Desktop, choose Properties
Click the Appearance Tab.
Click Advanced button.
Choose Icon from the drop-down list
Set it's size to 31 and press OK, OK.
The changes will be applied now. Repeat the above steps and then set the Icon size back to 32 (defaults). The above steps are required to force Windows to redraw the icons
10) The Complete list ! Can u Do it!
Try to create a folder in Windows with either of these names--
"con" or "nul" or "Aux" or "Lpt1".
Windows will not let u create ....
This s coz these refer 2 some well known ports....
-con corresponds to the console
-Lpt1 corresponds to printer and so on....
well dat was common but hw bt this ? Try these more
CON, PRN, AUX, CLOCK$, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9.
TURN NUMLOCK ON AT LOGON.!!
NumLock does not toggle on by default (system-wide), even if you have it set in your PC's BIOS, because of XP's multi-user functionality. Guess Microsoft doesn't know everyone actually turns it on, which should be reason enough for what acts as "default"...
Anyway, you can hack the Windows Registry to change this behavior, or run a script at logon to turn NumLock on.
1. To enable NumLock through the Registry:
* Open Windows' Registry Editor (START > RUN, type "REGEDIT").
*. Navigate to HKEY_USERS\.Default\Control Panel\Keyboard.
*. Change the value for InitialKeyboardIndicators from 0 to 2.
2. To enable NumLock using a script, see this MS Knowledgebase article for complete instructions:
CODEhttp://support.microsoft.com/directory/article.asp?ID=KB;EN-US;Q262625
Option 1 is the quicker method, but if you have more than one user on your system and one or more don't want NumLock on (stranger things have been known of), then option 2 is the way to go since it allows you to only attach the script to specific users.
REMOVING SERVICES DEPENDENCIES.!!
This will allow you to disable a service or uninstall it from your system without effecting another service that depends on it. Here's how you do it
1. After you have set your services the way you want them and you have disabled/uninstalled something that another services depends on, run "regedit"
2. Under HKEY_LOCAL_MACHINE\System\find the service that will not function, do to another service being disabled/uninstall (found in ControlSet001\Services, ControlSet002\Services, and CurrentControlSet\Services)
3. Once you have found the service right-click on the string value, "DependOnService,"and modify
4. You should now see a list of services that it is dependent on. Simply delete the service that you have disabled/uninstalled
5. Restart your computer and your ready to go Disclaimer REMEMBER TO BACKUP YOU REGISTRY FIRST I'm not totaly sure if this will have any negative effects on your system. I used this method after uninstalling "Netbios over Tcpip" from my system completely, so that my Dhcp service would function and I have had NO negative effects on my system.
