Automatic Lamp Dimmer Circuit using Triac
Lamp dimmers circuit can be found through out the internet since these kind of circuits are have a great significance in real time.  Here is a similar circuit which was used to control a AC lamp connected to it based on the light present in the environment. To summarize, this will make the lamp glow brighter in the absence of light and in the presence of light the lamp will glow dim or will be turned off. Lets move into the working of this above lamp dimmer circuit.

40 Watt Inverter Circuit using CD4047

Simple 40W Inverter Circuit
Inverter Circuits vary with the power requirements and been widely available all over the internet. Here is a inverter circuit which uses IC CD4047B and some transistors to perform the desired action. First of well for those who are not aware of inverters here is something to give you the idea about it. Inverters is nothing but an apparatus which converts direct current into alternating current. So with the help of this circuit you can power a simple household AC appliances such as lamps using a 12v Battery. This will help in meeting up the energy demands, power failures and to places where the wiring is not possible. Lets move into the working of this simple inverter circuit.

Meetings are Going Mobile

modern-mobile-video-conferencing
The modern lifestyle is all about dynamism and time is the most precious asset. People earn by the hour and it has resulted in a fast paced life. As people get busier, there is less time to interact, and we find ourselves away from the person(s) we want to interact with. Even when we are away from the people we need to talk to, there is always a need for us to interact with them face to face. A face to face interaction keeps the human touch alive. When there is a business meeting that requires a closer interaction between members, video conferencing comes into play. There are also instances where you need to schedule meetings between two or more parties located far away from one another, at a moment’s notice.

Dual power Supply Circuit
Power supply form the basic building block of any electronic circuits and therefore its important to familiarize the DC power supply circuit construction. The above given circuit illustrates a simple approach to construct a dual DC power supply of 5V and 12V from the 230V AC mains supply. The Voltage ranges 5V and 12V are widely used in all kinds of simple electronic circuits, so its meaningful to learn this simple construction.
