Not showing My Computer Icon on Desktop in Windows 8 & 8.1

My computer icon is most important icon in windows operating system. In previous Operating Systems, like Windows 7 and Windows XP you can go to start menu and Right click on My computer icon and Show on Desktop for My Computer icon to show it in desktop. But the traditional start menu also missing in Windows operating systems, therefore ‘Show on Desktop’ is not available here.

How to Show My Computer Icon on Windows 8.1 & 8 Desktop
It is easy and few steps, I’ll be explaining the steps by steps with screen print.

   1. Right click in any empty space on the Desktop and click Personalize from the popup menu.

   2. Change desktop icons link on the left pane.

3. On the Desktop Icon Settings dialog box, select the Computer check box so there is a check mark in the box and ok. you can use this method such as the Control Panel and Recycle Bin. 

Now you can see your My Computer icon on your windows 8 Desktop.

Practical Resistor value calculation

Resistor is a passive electrical component that reduce flow of electrical current in an electronic or Electronics circuit. resister has a linear IV ( V=IR ) characteristic. meaning that the voltage across the resistor is directly proportional to the current through the resistor.
Resisters's 10³ Symbol

Resistor In Ohms	Unit	Symbol
1	Ohm	Ω
1,000	Kilo Ohm	KΩ
1,000,000	Mega Ohm	MΩ

Resistors practical value

Resistors only come in specified values. These values are spread across multiples of ten.

1.2

1.5

1.8

2.2

2.7

3.3

3.91

4.7

5.6

6.8

8.2

After that, the cycle repeats, but a power of ten higher.

Resistor Color code

Color	Significant figures	Multiplier	Tolerance
Black	–	×100	-
Brown	1	×101	±1%
Red	2	×102	±2%
Orange	3	×103	-
Yellow	4	×104	-
Green	5	×105	±0.5%
Blue	6	×106	±0.25%
Violet	7	×107	±0.1%
Gray	8	×108	±0.05%
White	9	×109	-
Gold	–	×10-1	±5%
Silver	–	×10-2	±10%
None	-	-	±20%

Example Calculation

Eg 1

Red      Red    Orange   Gold    

  2               2            000        ±5% 

  22000 Ω  ±5%    Or    22 KΩ

Eg 2
Blue      Gray   Brown    Silver
  6                8            0            ±10% 
  680 Ω  ±10% 

Power rating Of Resistor 
  power rating of a resistor is the specification given with a resistor that serves to tell the maximum amount of power that the resistor can withstand. When current passes through Resistor, it normally generates heat. there for we have to find suitable wattage resistor for the Electronics circuit.
 Let's look at examples of resistors and the power ratings we would need for them for you to get a practical idea:

Resister Value                    820 Ω
Resister between Voltage     12V

P = V² / R

P =12 x 12 / 820
p = 0.1756

1/4 watt resistor would suffice and be suitable for the circuit

The common standard power ratings of resistors are 0.25W, 0.5W, 1W, 2W, 5W, 10W and 25W. So the circuit designer must choose accordingly for the circuit.

How to configure Thomson TG 585 V8 Router for bridge mode ( Ooredoo Thomson Router configure for Wifi access point )

How to configure your Adsl Thomson  TG585 v8 Router ( Qatar Ooredoo white color Router ) for wifi access point. It is very simple step. I think now you have a Thoson   TG 585 V8 Router also if you don't know your Thomson Adsl router password you have to find Ethernet pach code. last think is download Thoson TG 585 V8 router brige mode configuration file. Click below  Mediafire link and download configaration file 

Download Thomson TG 585 V8 configuration File 

Thomson Router IP adress       192.168.1.254
Thomson Router User name    Administrator
Thomson Router Password      connect2th

Connect to your router through Wifi or using Ethernet cable. Now open your internet browser and type 192.168.1.254 IP address go to router logging web interface. then enter user name and password after you are direct to Thomson TG 585 V8 router configuration page. then upload configuration file .flow the below step to upload configuration file or see the video.

Thomson Gateway -------> Configuration ---------> Save or Restore Configuration ------> chose file
------> Restore configuration now

Now your router ready to user as a wifi access point. but there is a common wifi name and logging password. flow the below step for password change or see the below video. It is current password is srilanka

Home Network -----> Wireless ------> configure -------> then change WEP Encryption Key and Network Name (SSID) and click apply button
