Bol News TV Live - BOL, a new TV Channel is being launched soon. It will bring a revolution in media industry of Pakistan. The company is consisting of highly skilled professionals from all the regions of Pakistan. Currently, they are hiring new staff for their departments; Technical areas, Administration and Production. Bol Media Group has created thousands of employment opportunities by providing upgraded over 20,000 public transport across Pakistan. BOL is providing free repairs and an opportunity to vehicle owners to earn their living and elevate their quality of life. These vehicles are being upgraded free of cost with an ambition of revamping Pakistan’s public transport industry. It also provides the people of Pakistan a better travelling experience and an addition to the beauty of Pakistan. At BOL TV, we are working to become one of the leading channels of Pakistan, generating more than 50% of the revenues and profits of every global media market that we enter. At the same time we deploy our core competencies towards the socio-economic development of Pakistan. This is our mission and everything we do reflects this. Axact is well known name in the field of IT related products & services in Pakistan and it is serving IT industry since 1997 with full enthusiasm. It has global presence in 100 courtiers with 3.5 million customers worldwide. Axact offers significant contribution in the socio economic realm of Pakistan and now a new channel is coming up as a media revolution. Recently, Bol TV has hired its management and executive team which comprises of Nabeel as the President and CEO of Bol TV, media professional Faisal Aziz Khan joined Bol TV as the Senior Executive Vice President, reputed journalist Nasir Baig Chughtai as Senior Executive Vice President. Bol TV Network started off its journey with the extension in the professional workforce with some renowned names including Mr. Kamran Khan, Waseem Badami, Iftikhar Ahmad, Asma Shirazi, Muhammad Usama Ghazi, Nabeel Farooq Jakhura and Nadeem Raza along with many others. We are here to create better Pakistan through this Television Channel "BOL News TV". Bol News has started it's test transmission on 21st May 2015.

Monostable 555 Multivibrator Circuit

Monostable 555 Multivibrator Circuit

Electronics SHAH JEE PRODUCTION   August 02, 2015

Monostable 555 timer multivibrator circuit (one shot monostable multivibrator) is a retriggerable mono shot pulse generator. The name ‘Mono stable’ indicates that it has only one stable state. The unstable state is called ‘Quasi stable state’. The duration of stable state or the pulse width is determined by the charging time constant of the RC network. We can transfer the multivibrator from stable state to quasi stable state by using  push button trigger switch. The animated (simulated) working of the mono stable 555 multivibrator is shown in this article. You can use our monostable 555 timer calculator tool to find the duration of pulse(width) easily.

Components required

• IC 555
• Resistors (1MΩ, 100Ω)
• Capacitors (1µF, 0.001µF)
• LED Push button switch

Working of monostable multivibrator

• Output of monostable 555 multivibrator remains in its stable state until it gets a trigger.

• Primarily the transistor and capacitor are shorted to ground, this state is considered as the stable state of monostable 555 multivibrator.

• As we know, when the voltage at the second pin of 555 IC goes below 1/3 Vcc, the output becomes high. This high state is known as ‘Quasi stable state’. (Refer Astable multivibrator using NE 555)

• The trigger causes the transition from stable state to quasi stable state.

• So when we press the button (Trigger), the voltage at 2nd pin become less than 1/3 Vcc (disconnected from Vcc) and hence the output becomes high.

• Then the discharge transistor is cut off and capacitor starts charging towards Vcc (Refer the internal circuit below). Charging of capacitor is through the resistor R1 with a time constant R1C1. 

• As the capacitor voltage increases and finally exceeds 2/3 Vcc, it will reset the internal control flip flop, there by turning off the 555 timer IC (more than 2/3 voltage at the threshold pin (6th pin) causes IC to reset).

• Thus the output goes back to its stable state from Quasi stable state.

Proteus Professional 7.5 SP3 ISIS with crack

This is one software that very famous for electronic and microcontroller design and simulation this day. There are many electronic and microcontroller project designed using Proteus software because this software easy and also powerful. One of the Proteus is Proteus 7.5 SP3 Full Version.

Description

Still review about Proteus that related with Proteus 7.5, when we want to use Proteus to create the electronic schemetic circuit, firstly we can draw electronic circuit schematic according our schematic project the needed. We can use many tools that provided by Proteus software. We can use tools like component that needed, connector, and also wiring that needed.

After we drawing our circuit schematic, we can continue take simulation our schematic to know how are our project will work properly. We also can use many tools to simulate our project. And after simulate we can continue make PCB layout according the electronic circuit schematic that used. 

For you how hobbies with microcontroller, with using Proteus software you will easy to know with simulation that provided by Proteus. With Proteus software, you can make circuit schematic frommicrocontroller project, insert your microcontroller instruction to IC microcontroller, and then we can do simulation to know how are our program microcontroller will work according the circuit schematic that built. So with Proteus software we can get many advantages.

One of the old Proteus software version that developed is Proteus 7.5 SP3 Full Version for Electronic Design Simulation. And in here we will give you link to take Free Download Proteus 7.5 SP3 Full Version for Electronic Design Simulation from external server.
