In this project 3.7 volts battery low full indicator, we are going to make a very simple battery level indicator. This indicator circuit is for 3.7 volts indicator. We have designed this circuit with few components at home with easy available components. These components can either be collected from an old circuit or can be […]

Low power audio amplifiers. There are a multitude of low power amplifiers using integrated circuits, I will show some quite common, easy to make and generally low cost. Most of these amplifiers are used by televisions, test and measurement equipment, old modems, etc. At present there is talk of sound equipment of “10,000 Watts PMPO” […]
In this project we are going to built a simple IC 4440 amplifier circuit but the output is very nice and very high. It is 12 volts audio amplifier using is LM4440 IC 19 Watts amplifier. We have designed it without PCB and used few capacitors with it. we can use it in car audio […]
Traffic Lights controller are used to control the vehicular traffic on the road. In the modern age, almost everyone has different types of vehicles that become the cause of traffic problems. That is why traffic lights signals are compulsory to avoid the traffic jams on the roads. There are three signals lights in the traffic […]
