7809 is a voltage regulator integrated circuit(IC) which is widely used in electronic circuits. Voltage regulator circuit can be manually built using parts available in the market but it will take a lot of time to assemble those parts on a PCB. Secondly, the cost of those parts is almost equal to the price of 7809 itself so professionals usually prefer to use 7809 IC instead of making a voltage regulator circuit from scratch. Before you start using 7809, you will need to know about the pin structure of IC 7809. Apparently, it looks like a transistor. It has three pins. For a better understanding, I have given an image of 7809 bellow. Please take a look. Read the rest of this entry »

There are a lot of people who are addicted to nail biting. Research indicates that mind stress, depression, muscular stress, lack of confidence and need of rest are some of the possible reasons behind nail biting habit. There are many people who bit their nails because they have become long and they don’t have time to grab nail cutter. If you are addicted to nail biting habit then be aware that this can cause your nail to become ugly looking. You can also trigger dangerous infections caused by your nail biting habit.

Addiction is a mental condition of a living being in which the body of that living being craves to do some act or to have some thing. When you cannot stop yourself from doing any act in particular then it means you are addictive to that act. There are many kinds of addictions. Most common of them are drug addiction, smoking addiction and sexual addictions. Almost all kind of addictions have a cycle like scenario before you act them out.
First your start fantasizing about doing the act you are addictive to, then in second step, you become excited about it, in third step, you become some much excited that you ignore any thoughts being generated by your mind against that act and start to do that act, in the last step which is actually after doing that act, you become guilty on your act and promise yourself that Read the rest of this entry »
Power inverter is a very useful device which can convert Low voltage from a DC source to high voltage AC. The most common power inverter is 12V to 240V inverter. Perhaps that is because 12V batteries are common. This type of power inverter usually draws current from a DC battery. This battery should be able to provide a high flow of electric current. Normally lead acid batteries can server this purpose well. This current is then converted to 240V square wave alternative current so that we may empower those electric appliances which work on 240V instead of 12V. Inverter falls in the category of expensive devices so many people don’t buy them even they need them. What if I tell you how to build an inverter yourself?
Toyota always builds great vehicles.Toyota Hiace Commuter Bus is another great passenger bus developed by Toyota. It is very comfortable and provides a pleasant travel experience. Toyota Hiace Commuter bus can accommodate 15 passengers (It is because of Japanese law) but you can add some more comfortably if allowed by the law in your country. Till now, the hiace commuter bus models I have seen were right hand drive only. This Toyota bus is available in both Diesel as well as Petrol versions. The diesel engine bus is 3000cc and the engine type is 1KD-FTV. The Petrol (Gasoline) engine bus is 2700 cc and the engine type is 2TR-FE. The diesel version is available as 2WD only however the Petrol version is available in both 2WD and 4WD. Toyota hiace commuter bus enjoys a fully automatic transmission Read the rest of this entry »
