This PIR Motion Sensing Security Light Circuit is a very nice project for person who love electronics. Furthermore, this circuit uses a special sensor for security; unlike normal switches that turn lights ON and OFF manually, this light includes a built-in motion sensor. Here, the sensor can see the movement like someone is walking and […]

Cellphone Triggered Car Amplifier Auto Mute Circuit
This article for Cellphone Triggered Car Amplifier Auto Mute Circuit show how to make one simple circuit, like when phone ring it turns OFF the car music by itself. So no need to rush or search button to stop music when call is coming. What is a Cellphone Triggered Car Amplifier Auto Mute Circuit: The […]
Simple Contact MIC Circuit
Simple Contact MIC Circuit is special mic, it can record weird sound when we put it in different things; also if we give it small electric power it can even make sound by itself. We can use a contact mic and a simple wire setup to make a normal guitar sound like an electric guitar […]
Simple Lie Detector Circuit using Transistors
Have fun making this Simple Lie Detector Circuit using Transistors. Real lie detectors are very hard and complicated so this one is not perfect; but it is fun way to see how body react when its in stress. Also, this circuit works by detecting changes in sweat to check whether someone may be telling the […]
Simple RF Sensor without Battery Circuit
This article for Simple RF Sensor without Battery Circuit show how to make small tester with no battery, also it help to check if radio transmitter is working or not. Moreover, the tester receives power from radio waves sent by the transmitter and if the transmitter works properly, the LED light blinks to indicate it. […]
Simple Metal Detector Circuit
This article show a special trick to make a Simple Metal Detector Circuit, which uses simple circuit not like other circuits and needs only one transistor. The circuit find metal by catching signal from a normal radio. What is a Metal Detector: A metal detector is an electric circuit that checks whether metal is nearby, […]
